Passage 1
(2026·广东梅州·一模)
For generations, sharing a bed has been widely seen as a key sign of closeness for couples. But a quiet shift is taking place in some Western countries. The trend, called “sleep divorce,” is not about ending a relationship. Instead, it means partners choose to sleep in separate beds or even separate rooms to improve their sleep quality.
Sleep divorce is a practical response to common sleep problems, such as snoring, different bedtimes, disagreements over room temperature, shift work, and so on. And stress-related sleeplessness are among the main reasons couples consider sleeping apart. Importantly, this choice is not a legal separation nor a sign of marriage trouble.
Several forces are driving this trend. First, sleep troubles are rising worldwide, linked to noise, stress, and late-night screen time in modern life. Second, snoring affects up to half of adults, far more than many realize. Third, health is becoming a higher priority than tradition; couples now see good sleep as essential to well-being, just like diet and exercise. Finally, younger generations are redefining relationship success, valuing flexibility over fixed rules about how couples “should” sleep.
Interestingly, sleeping separately often brings couples closer. With better rest, they report fewer arguments, better moods, and clearer communication. Poor sleep can make people easily annoyed and less empathetic, while solid rest supports emotional strength.
Experts note that sleep divorce is helpful when partners feel bitter due to constant sleep interruption, wake up tired despite enough time in bed, or deal with heavy snoring. But it can backfire if it’s used to avoid dealing with relationship conflicts, if one partner feels lonely or rejected, or if the decision is not mutual. Therapists advise couples to talk about it as a health choice for both people, not as a way to escape each other. As health and relationship satisfaction take priority over old expectations, sleeping apart may become a normal option for more couples in the future.
1. What is “sleep divorce” according to the text?
A. A legal step to end a marriage. B. A sleep arrangement to improve rest.
C. A solution mainly for shift workers. D. A trend of avoiding emotional connection.
2. What does the word “backfire” in paragraph 5 probably mean?
A. Improve quickly. B. Gain popularity.
C. Succeed unexpectedly. D. Cause harm instead.
3. What can be inferred about younger generations in paragraph 3?
A. They stick to traditional sleep habits. B. They experience fewer sleep problems.
C. They value health less than older couples. D. They are more flexible in defining relationships.
4. Which of the following is the best title for the text?
A. Why couples Choose to Sleep Apart. B. Get a Divorce: For a Better Sleep
C. The Science Behind Better Sleep. D. How to Design a Dual-Bedroom Home.
Passage 2
(2026·湖南衡阳·一模)
Despite decades of messaging from litter prevention campaigns, trash still finds its way onto streets. A Portland-based organization has been inspiring residents to clean up their neighborhoods, one block at a time. Since 2020, Adopt One Block has helped over 7,000 people become Block Ambassadors. These volunteers beautify and maintain over 8,500 blocks in Washington and Oregon.
Sarah Yapp adopted her block in south Eugene. With cars rushing by, she explained why. “When I was growing up, my dad actually made me pick up trash on the street. That was the era of McDonald’s Styrofoam (泡沫塑料) containers, when people just threw them out of their windows. So, I used to hate that,” she said. “And then I grew up, and I realized I don’t like trash on the street as an adult either.” “Oh, I got something!” Yapp used her grabber to pick up a paper cup from a bush and dropped it in a bag.
Olivia Langley is Director of Operations for Adopt One Block. “We send you free clean - up supplies,” she said. “That’s everything from a bucket, a trash grabber, trash bags, to gloves.” Block Ambassadors set their own schedules for trash grabbing and can access additional resources from the organization to deal with different “trash encounters”. Langley said that when necessary, medical sharps containers are also provided.
However, Langley insisted that volunteers should only do the amount of clean-up they are comfortable with. Things like broken glass, thrown - away needles and perilous materials can be handled by municipal agencies, she said.
Sarah Yapp shared the idea with her friend Rachel Sanders and now they both pick up trash on their own blocks and beyond. The friends said the garbage can sometimes be messy, but they both find fulfillment in cleaning it up. “Here we are picking up trash and there are people cheering us on and joining in. Some even adopt their own neighborhoods!” Yapp said. “The other day, a middle school student saw me on my block and asked, ‘Are you picking up trash? Thank you!’”
1. What made Sarah Yapp become a Block Ambassador?
A. Her father’s personal request.
B. The increase in McDonald’s products.
C. The technical support from the non - profit.
D. Her own appreciation of a clean environment.
2. What do we know about Block Ambassadors’ work according to Olivia Langley?
A. They follow a very tight schedule.
B. They handle various kinds of trash.
C. They have good medical insurance.
D. They protect their blocks from danger.
3. What does the underlined word “perilous” in paragraph 4 mean?
A. Dangerous. B. Simple.
C. Unwanted. D. Unclean.
4. What does the last paragraph mainly talk about?
A. The positive impact of Sarah’s work.
B. The financial value of Sarah’s efforts.
C. The friendship between Sarah and Rachel.
D. The personal satisfaction from volunteering.
Passage 3
(2026·河北承德·一模)
A few weeks ago, an article by Nathan Heller in The New Yorker indicated “the end of the English major”, examining the trend of declining English department nationwide and the cultural factors that lead students away from spending four years with the passion for Dickens and Shakespeare. Like every other humanities-lover on a college campus that day, I was swept away in the mass panic. My major was, according to a reputable English-major-loved publication, dead.
Heller focused on Arizona State University (ASU) and Harvard University, large “indicators”(higher education. I initially thought he ignored small liberal arts (文科) colleges, assuming English major were safe at Allegheny College, where students supposedly came for the love of learning, not for middle management when they graduate. But data ruined this hope: Allegheny had 84 English majors (9% of all majors) in the spring semester of 2003, but just 20 (2.5%) now — a 72% drop in about 20 years matching the national trend.
Allegheny’s website fuels optimism, asking, “Why put your mind to just one thing?” and define itself as a “safe place of learning”, unlike ASU, which sees degrees as career stepping stones, or Harvard where, according to Heller, even an “unusual major” finds work. Yet campus reality in Allegheny differs Students get locked into majors early, “mind over major” loses to closed-off departments, and English majors fear unemployment, thinking they wasted time and money.
We need to reject the campus “disease”, Heller noted — pressuring students to choose “safeguard paths and dismissing humanities as “hobby-based”. The well-known author Kurt Vonnegut reminded you that the arts may not be the best way to “make a living” but “make life more bearable” and “make soul grow”. Not everybody can or should pursue a degree in chemistry, but it is increasingly clear to me that everybody would benefit from spending 20 credit hours reading, thinking about and discussing literature. While English majors may decline, their lessons live on. As the novelist Jonathan Lethem wrote, “Time change and men adapt.” Between “too bad” and “worst”, we can do better.
1. What phenomenon did Heller point out about English literature?
A. Students’ fading love for it. B. Its limited research visions.
C. Students’ confusion about it. D. Its declining literary works.
2. Why did the author’s hope for Allegheny College fade?
A. It closed most liberal arts majors. B. It valued career training more.
C. It admitted fewer English majors. D. It cared less about students’ likes.
3. What can be inferred from Allegheny’s website?
A. It tried to learn from Harvard. B. It didn’t match its real situation.
C. It failed to ensure students’ safety. D. It didn’t promote critical thinking.
4. What does the author advocate in the last paragraph?
A. Students should plan a unique life journey. B. Schools must make English more inviting.
C. Students need to stick to their own purposes. D. Schools ought to look beyond practical values.

Ethics (伦理) in Cybersecurity by Marquez, a former cybersecurity analyst for a global tech firm, is a timely exploration of the moral dilemmas that define modern digital life.
The book is organized around six “ethical crossroads”, each illustrated with a detailed case study. One of the most striking chapters focuses on the 2025 “SecureData” case, where a major tech company discovered weakness in its popular messaging app — one that could expose users’ private conversations. The company faced a choice: tell users the problem immediately or fix it quietly over six months. Marquez walks readers through the arguments on both sides: the “duty to protect users” versus the “duty to avoid bad reputation”. She doesn’t offer a simple answer — instead, she teaches readers to weigh conflicting values, a skill she calls “ethical reasoning for the digital age”.
Marquez also challenges common myths about cybersecurity ethics. She argues against the idea that “the end justifies the means” when it comes to fighting cybercrime, citing a 2024 case where a government accessed a criminal group’s servers to recover stolen data, but in doing so, accidentally obtained the private emails of 10,000 innocent people. “Security without ethics isn’t security — it’s just control,” she writes. This focus on balancing security and ethics makes the book stand out in a field often dominated by technical solutions.
Marquez’s engaging style makes the book accessible. She, for instance, compares a company’s decision to hide a software problem to “a teacher knowing a classroom door is broken but not fixing it because he doesn’t want to stop class.” She also includes “Ethical Checklists” at the end of each chapter, which guide readers to apply the book’s lessons to their own lives, for example, should you report a friend who shares your password with others?
Overall, Ethics in Cybersecurity is more than a book — it’s a tool for thinking critically about daily digital choices. As Marquez puts it: “In cyberspace, every click is a choice — and every choice has an ethical cost.”
1. What can be inferred from the 2025 “SecureData” case?
A. Companies prioritize user privacy. B. User data is hard to protect.
C. Cyber ethics involves tough choices. D. Messaging apps are easy to access.
2. Which of the following is Marques probably against according to paragraph 3?
A. Download papers on the CNKI. B. Polish an article by DeepSeek App.
C. Give a thump-up on a friend’s Moments. D. Disclose a friend’s address on the internet.
3. What is a feature of Ethics in Cybersecurity according to the text?
A. It is packed with complex theories. B. It provides step-by-step instructions.
C. It is intended for cyber professionals. D. It adopts a down-to-earth writing style.
4. What is the author’s purpose in writing the text?
A. To publicize cybercrime prevention. B. To honor a talented technical expert.
C. To introduce a book on Cybersecurity. D. To recommend an essay on digital life.

Passage 1
(2026·河北石家庄·一模)
Many environmental and behavioral factors can affect the body’s internal clocks, which control various body functions. However, modern life can throw off these biological times, increasing our sensitivity to different conditions. Light, a major factor affecting the body’s internal clocks, has long been linked to various health impacts. This is evidenced in populations like shift workers, who face a higher risk of heart disease due to night-time light exposure.
Previous studies that used satellite data found associations between people living in bright, urban areas and heart disease, but they only measured outdoor light at night. Daniel Windred at Flinders University and his colleagues wanted to know whether an individual’s overall light exposure was associated with heart problems.
They tracked about 89, 000 people without heart disease who wore light sensors for one week between 2013 and 2016, which is the biggest study of personal light exposure patterns and heart health to date. The sensors recorded any natural or artificial light from their environment, including that from phones. Over years, those with the brightest nights had a higher risk of developing heart disease than those with dark nights. One representative case in the highest light exposure group would be someone who turned on overhead lights for an hour between midnight and 6 am. “This means they have among the highest night light exposure — within the top 10% of all participants,” says Windred. He adds that the body continues to react to an artificial light after it has been turned off, and even short exposures can have an effect.
The researchers controlled for factors like gender, age, smoking, and shift work. They also showed that the association between light exposure and heart disease risk was independent of sleep duration or quality, pointing to night light exposure as the key driver of the results.
“The importance of these observations cannot be underestimated,” says Martin Young at the University of Alabama at Birmingham. “With the coming of a society that operates around the clock, disturbing our biological clock systems has become more and more common. This study highlights the significant health dangers associated with exposure to light at the wrong time.”
1. How are the health impacts of light exposure presented in the first paragraph?
A. By providing data. B. By citing a document.
C. By giving an example. D. By making an assumption.
2. What does paragraph 2 stress about previous studies?
A. Their limitation. B. Their goal.
C. Their uniqueness. D. Their process.
3. Why is the case in paragraph 3 mentioned?
A. To applaud a research method. B. To clarify a study classification.
C. To define a cause of heart disease. D. To describe a common sleep habit.
4. What is Martin Young’s attitude to the research findings?
A. Supportive. B. Cautious. C. Picky. D. Anxious.

Jim Thorpe is one of the greatest athletes of all time. He had amazing athletic abilities and was well-known during his lifetime, yet that did not make Thorpe a stranger to adversity.
Thorpe was an American Indian from Oklahoma who developed his extraordinary athletic skills in his youth through hard labor. It was also in his youth that he learned to endure hardship brought upon by racial prejudice. Many would say his childhood was not easy. He grew up poor and at age 9 his twin brother passed away and a few years later he lost both of his parents.
But that did not stop him from doing what he loved and pursuing his dreams. Nothing seemed to stop him, not even stolen shoes. Just hours before Thorpe was going to compete in the 1912 Olympics, somebody stole his shoes. Thorpe improvised (临时拼凑) by getting shoes out of the garbage. The shoes were two different sizes. He wore an extra pair of socks on one foot to even them out.
He still went on to win two gold medals—winning each event he competed in except for one, the javelin (标枪). The javelin was the only event he didn’t win, probably because he had never competed in that event before. It is interesting to note that Thorpe had tried to throw the javelin once before in the Olympic trials. At the time, he didn’t know that he could throw it with a running start. He threw it standing still and was placed second.
At the Olympics,he also took part in the decathlon (十项全能运动). He finished first in two events, third in four events, and fourth in two more. Thorpe ended up finishing third in the world. He was undoubtedly a dominating force that couldn’t be stopped and just kept on going.
I think Paul Dughi said it best, “It’s hard to imagine now that pro athletes get paid millions of dollars just to wear a particular brand of shoes. For Jim Thorpe, it didn’t matter what kind he wore.”
1. What does the underlined sentence in Paragraph 1 mean?
A. The adversity Thorpe met with led to his success.
B. Thorpe’s success was no guarantee of a better life.
C. Thorpe’s career brought him both gains and losses.
D. Thorpe suffered many hardships despite his success.
2. Why did Thorpe wear more socks on one foot?
A. To prevent the foot from injury. B. To make the shoe fit the foot.
C. To stop the shoe from being stolen. D. To show his problem-solving skills.
3. What most likely led to Thorpe’s failure to win the javelin?
A. Loss of his own sports shoes. B. A casual attitude towards the event.
C. Lack of experience in the event. D. A shortage of talent for the event.
4. Which of the following words can best describe Jim Thorpe?
A. Loyal and enthusiastic. B. Genuine and creative.
C. Tough and strong-minded. D. Selfless and good-tempered.
Passage 3
(2026·山东德州·一模)
You’ve followed all sleep experts’ advice — going to bed on time, avoiding afternoon coffee, and keeping your bedroom cool as you like, dark with no light on, and quiet as possible — yet you still toss and turn. Glancing at the silver light through the curtains, you wonder: Could the full moon be ruining your sleep?
Figuring out the moon’s impact on human sleep is challenging, as emotions and expectations often cloud judgments. Many people romanticize full moons, especially special events like harvest or blue moons, while others anticipate restlessness under a full moon, which alone can disrupt sleep. Scientific studies suggest real physiological effects caused by the moon.
In a 2013 study, Swiss researchers analyzed data from an experiment in which participants had no idea their sleep was being studied for lunar effects. Around the full moon, participants experienced a 30 percent drop in deep-sleep brain activity, took 5 minutes longer to fall asleep, and slept 20 minutes less overall. They also reported worse sleep quality and had lower levels of melatonin, the hormone (荷尔蒙) that your body releases naturally at night to calm your body down and prepare you for sleep. However, all these studies share one major limitation: they were conducted in sleep laboratories, where the subjects may be disturbed easily by the unfamiliar setting.
To address this, University of Washington researchers tracked sleep in real-world environments: three Argentinian communities (urban suburbs, rural village with limited electricity, remote area with no electricity) and 464 Seattle university students. Across all groups, regardless of artificial light access, participants slept less and took longer to fall asleep in the nights leading up to a full moon. The researchers think this may reflect an ancient adaptation: When the moon was brightest, our ancestors likely stayed up later to hunt, socialize, or work by natural light.
The sleep changes were most obvious in low-electricity communities, where moonlight remained the main light source at night. Sleep experts note that while the full moon’s effect, up to one hour less sleep, is profound, artificial light from screens likely has an even greater impact on modern sleep.
1. What is the difficulty in studying the moon’s effect on sleep?
A. People’s habits and hobbies. B. Health conditions and sleep space.
C. Artificial light or noise in the room. D. People’s emotions and anticipations.
2. What did the 2013 Swiss study find about full moons?
A. They caused 25 minutes less sleep on average.
B. They affected people more in the real world.
C. They had less impact on sleep than expected.
D. They led to a reduced deep-sleep brain activity.
3. Why did University of Washington researchers adjust study surroundings?
A. To compare sleep patterns by age group.
B. To analyze the influence of artificial light on sleep.
C. To avoid the impact of strange settings on subjects.
D. To test whether urban lifestyle cancels lunar effects.
4. Which would be the best title for this passage?
A. The End of Moonlight Folktales B. City Lights’ effects on Human Sleep
C. Moonlight’s battle with artificial light D. The Moon’s Silent Theft of Our Sleep
Passage 4
(2026·山东青岛·一模)
I first encountered the classics at 19, when I studied English literature at university. But a lack of life experience, combined with exams, essay deadlines and an obsession (痴迷) with good grades, left me little time to truly concentrate on them – Middlemarch, The Picture of Dorian Gray, Pride and Prejudice, Madame Bovary etc. I loved these books, yet I never got the chance to deeply engage with them.
Some 40 years later, as an editor, it’s now my job to figure out what makes a book tick or more often, what it needs to make it tick. So, when a coworker suggested we deconstruct classics to find their “secret to lasting appeal”, I was intrigued. I decided to reread Middlemarch, which I had loved before but never fully grasped. I did hesitate a bit, though; could I, with my attention constantly distracted by technology, handle its 900 pages of tiny print?
Not wanting to hold back entirely, I tried the audiobook instead. The audio’s vivid delivery certainly drew me in, but what truly took me aback was the new understanding that came with age. Themes that felt distant at 19 came into sharp focus at 60: ideas of marriage, ambition, and unmet expectations that had flown over my younger head now echoed (回响) deeply within me. I also noticed striking similarities in other classic characters: Emma’s desire for an “ideal life” in Madame Bovary mirrors the social comparison we see on social media today, and Dorian Gray’s obsession with youth in The Picture of Dorian Gray reflects our selfie-obsessed culture.
Then came the real work: taking them apart to see why they’re classics. Some were easy to analyze, others tricky, but we gave them the attention they deserved – more than I ever could at 19. What struck me most was that classics last not for their age, but for capturing universal human truths: desires, fears, and hopes that never fade. Rereading them isn’t just about revisiting old tales; it reconnects us to our unchanging human nature, enriches our understanding of time, and grows with us as we do.
1. What does the author imply about the classics in paragraph 1?
A. They enriched his experience.
B. They proved too difficult for him.
C. They made for his academic success.
D. They failed to obtain his full appreciation.
2. What does the underlined word “intrigued” in paragraph 2 mean?
A. Hesitant. B. Interested. C. Fulfilled. D. Puzzled.
3. Why does the author mention Emma and Dorian Gray?
A. To show classics’ modern relevance.
B. To criticize current social problems.
C. To present impressive analytical skills.
D. To highlight their lasting popularity.
4. What can be a suitable title for the text?
A. Busy Youth, Fading Truth
B. Modern Whisper of Audiobooks
C. Changing Trend, Unchanging Insight
D. Time’s Echo of Literary Classics

Passage 1
(2026·广东汕头·一模)
A wildfire burns in the hills of a Los Angeles suburb, leaping from one dry bush to another. As it approaches the first house, the plants around it catch fire, but the house itself stubbornly refuses to do so: any small flames along its walls quickly die out. There’s no water in sight — the flames are put out by sound waves.
This scene is not science fiction. Engineers at an American tech company built a device using low-frequency sound waves to fight fires. “It’s basically vibrating (震动) the oxygen faster than the fuel can use it, blocking the chemical reaction,” explains Geoff Bruder, an aerospace engineer who once studied heat engines for NASA.
Fire needs heat, fuel and oxygen; taking one of these away will stop the fire. Sound waves push oxygen away from the fuel, preventing the fire getting the air it needs to continue its burning. The company has demonstrated a fire control from as far as 25 feet away.
Using sound against fire isn’t new. A U. S. defense research agency studied it over a decade ago. However, a major challenge is to scale up the technology without creating loud or even damaging sound effects.
The company overcame this by using infrasound — sound waves at 20 hertz (赫兹) or lower, which humans cannot hear. These waves also travel farther than higher-frequency sounds. The device looks like a metal box attached to the roof. When heat sensors detect a flame, an electric motor drives a piston (活塞) to create infrasound, which travels through metal tubes on the roof, creating a “force field” to put out the fire and prevent the building catching another fire.
Experts note that while sound waves can effectively influence fire, they currently work best on smaller flames. Nevertheless, homeowners and large energy companies are game to give it a try: The company is working with two California power suppliers and plans to install fifty pilot units early in 2026.
1. What does the passage begin with?
A. A historical review. B. A personal anecdote.
C. A scientific explanation. D. A descriptive situation.
2. What is the basic principle behind sound-based firefighting?
A. It removes the burning material. B. It cools the fire with vibrations.
C. It separates oxygen from the fuel. D. It blocks the heat with natural force.
3. What is a key feature of infrasound?
A. It is silent to human ear. B. It is of high-frequency.
C. It travels at a fast speed. D. It requires loud volumes.
4. What does “game” in paragraph 6 most likely mean?
A. Pleased. B. Ready. C. Afraid. D. Unwilling.

Penguins are some of the world’s most familiar and beloved birds, but southern rockhoppers are the tough guys of the penguin world. Their fondness for colonies (聚居地) high over thousands of feet separates them from the other penguin species that prefer soft, level ground in the Falklands.
One evening, I struggle to keep up with some scientists as they march through thick grass in the Falklands. They are looking for rockhoppers that have pencil-case-size black boxes taped to their backs and collecting those boxes, which contain GPS data loggers (记录仪). Some also track diving and heart-rate information. Later, in the scientists’ field station, we gather around a computer screen, analyzing the collected data, which will give us a critical read on ocean conditions, revealed by the birds’ responses.
With a lifespan of 10 to 15 years, the species can withstand the occasional disaster and rebuild their population over time. But as colonies damaged by human activities struggle to recover, a string of disasters has knocked them down. Despite their bravery, rockhoppers are highly sensitive. Research by these scientists shows that even a small increase in sea temperature can affect the birds’ food supply and lower chick and adult survival. Besides, changing weather is causing unseasonably intense storms, killing chicks who haven’t yet grown their thick, waterproof feathers.
However, moving to cooler water isn’t an option. The constant winds there would push the little penguins into the icy coasts of Antarctica, and there’s no land where they could build new colonies. These scientists are trying to re-establish the native grass. “It may be impossible to stop the changes sweeping their ocean habitats,” Quillfeldt, a seabird ecologist says. “But to help them on land, at the breeding (繁殖) sites, is something we can actually do.”
Thinking of the young rockhopper leaping over a fearful gap, I ask the scientists: Can rockhoppers’ courage be an advantage for their survival? Quillfeldt feels it may. Curiosity and bravery can encourage seabirds to find ways to adapt. Don’t forget they’ve got attitude.
1. What is the function of the black boxes on the rockhoppers’ backs?
A. To locate GPS data loggers. B. To distinguish birds’ responses.
C. To analyze the survival rate. D. To record data about ocean conditions.
2. What may bring a challenge to rockhoppers’ population?
A. Their lengthy lifespan. B. Their fondness for high rocks.
C. Their thick waterproof feathers. D. Their sensitivity to the climate change.
3. What could be a practical way to help rockhoppers according to paragraph 4?
A. Establish new colonies. B. Improve the breeding sites.
C. Stop the environmental changes. D. Move to the coasts of Antarctica.
4. What is the author’s attitude toward rockhoppers’ future?
A. Hopeful. B. Reserved. C. Dismissive. D. Doubtful.

(2026·山东日照·一模)
Half the world’s 100 largest cities are experiencing high levels of water stress, with 38 of these sitting in regions of “extremely high water stress”, new analysis and mapping has shown.
Water stress means that withdrawals for public water supply and industry are close to exceeding available supplies, often caused by ineffective regulation of water resources and intensified by climate breakdown. Watershed Investigations and the Guardian mapped cities on stressed catchments revealing that Beijing, New York, Los Angeles, and Delhi are among those facing extreme stress, while London, Bangkok and Jakarta are classed as being highly stressed.
Separate analysis of NASA satellite data shows which of the largest 100 cities have been drying or getting wetter over two decades with places such as Chennai, Tehran and Zhengzhou showing strong drying trends and Tokyo, Lagos and Kampala showing strong wetting trends. Most of the city regions in notably wetting zones are in sub-Saharan Africa, with just Tokyo and Santo Domingo in the Dominican Republic sitting elsewhere. Most of the urban centers in areas with the strongest drying signals are across Asia, particularly northern India and Pakistan.
Now in its sixth year of drought, Tehran is critically close to “day zero” when no water will be available for its citizens, and last year the president, Masoud Pezeshkian, said the city may have to be relocated if the drought continues. Mohammad Shamsuddoha, professor of water crisis and risk reduction at UCL, said, “By tracking changes in total water storage from space, Grace, the NASA project, shows which cities are drying and which are getting wetter, offering an early warning of emerging water insecurity.”
Last week the UN announced the world had entered a state of serious water shortage where degradation of some resources had become irreversible (不可逆的). The World Bank Group has also been sounding the alarm. Global freshwater reserves have decreased sharply over the past 20 years, according to the group.
1. What does the author think leads to water stress?
A. Heavy water pollution. B. Poor water management.
C. Freezing climate. D. Large population.
2. What does NASA satellite data indicate?
A. Huge water loss. B. Severe water shortage.
C. Changeable rainfall. D. Uneven water distribution.
3. What is the purpose of Grace?
A. To control water use. B. To increase freshwater reserves.
C. To issue an alert in time. D. To slow down the drying trends.
4. What is the text mainly about?
A. The falling water storage across the world. B. The problems with global water regulation.
C. NASA’s efforts to track global water changes. D. Growing water risks faced by big cities worldwide.
Passage 4
(2026·河南濮阳·一模)
A study, published on November 6 in Science, identifies a specific biological “timer” that controls when a seed decides to “wake up” and grow, which could help protect the global food supply from the unpredictable effects of climate change.
The research involved scientists from top institutes in China, Denmark, France, and the United Kingdom, focusing on seed dormancy (休眠) — a natural state of sleep that prevents seeds from sprouting (发芽) even when environmental conditions appear favorable. While this helps plants survive in the wild, it creates what researcher Wang Yucheng calls a “double-edged sword” for modern agriculture.
Wang Yucheng, a professor at the Institute of Tibetan Plateau (高原) Research of the Chinese Academy of Sciences, explained that if seeds woke up too early, they might sprout while still attached to the plant before harvest. This ruins the quality of the grain and leads to more than $1 billion in losses annually. Contrarily, if the seeds stay asleep too long, they will not grow in time for the next planting season, throwing the entire farming schedule off.
Using advanced DNA mapping technology, the team identified the MKK3 gene as the master regulator of seed dormancy. Christoph Dockter explained that the gene’s copy number and activity determined dormancy length — more copies shortened dormancy.
The study highlighted a unique variety of qingke, found on the Qinghai-Tibet Plateau. Qingke’s unique MKK3 activity offers a natural solution to seed dormancy in cold regions. This variety has evolved what can be described as the world’s “highest-activity mode”. Through long-term selection and breeding, qingke has developed one of the strongest MKK3 activities globally, resulting in the weakest seed dormancy and the stronger sprouting capacity.
To adapt to the plateau’s extreme harvest-time cold, locals harvest immature grains and use post harvest treatments like air-drying and roasting for storage.
Wang stated the discovery offered a blueprint for “designing” stress-resistant crops. With climate changing, lost or weakened ancient genetic characteristics may regain value, and future research will try to recover these characteristics to improve modern crops.
1. What is the advantage of seed dormancy?
A. Help wild plants survive naturally. B. Improve grain quality effectively.
C. Shorten the growth cycle of plants. D. Adjust farming schedules perfectly.
2. What does the author try to illustrate by mentioning qingke?
A. Its sprouting ability. B. Its massive output.
C. Its unique gene activity. D. Its period of dormancy.
3. What can be inferred from the passage about future agricultural research?

Passage 1
(2026·山东青州·一模)
Pick up any packaged processed food, and there’s a decent chance that one of its listed ingredients will be “natural flavour”. The ingredient sounds good, particularly in contrast to “artificial flavours” since there is a common belief that ingredients from nature are necessarily safer than something artificially made. But it’s not true. Then what exactly does the natural flavour mean? It refers to extracts (提取物) got from natural sources like plants, meat or seafood. When consumers see the “natural flavour” on a label, they are unlikely to assume that someone is squeezing the juice from oranges into their bottles. They know even though natural flavour must come from natural sources, it needn’t all come from the plant or meat. For example, orange flavours might contain not only orange extracts, but also extracts from bark and grass.
So if flavours like orange are needed, why not just use oranges? The answer comes down to “availability, cost, and sustainability”, according to flavour chemist Gary Reineccius of the University of Minnesota. “If you’re going to use all your grapes on grape soda,” Reineccius says, “you don’t have any grapes for wine making; the products are going to be exorbitant; besides, what do you do with the by-products you create after you’ve squeezed all the juice out of the grapes?”
Actually, while chemists make natural flavours by extracting chemicals from natural ingredients, artificial flavours are made by creating the same chemicals artificially. The reason why companies bother to use natural flavours rather than artificial flavours is simple: marketing. “Many of these products have health titles,” says Platkin, professor from Hunter College. “Consumers may be talked to believe products with natural flavours are healthier, though they are nutritionally no different from those with artificial flavours. Natural flavours may involve more forest clear-cutting and carbon emissions from transport than flavours created in the lab.”
Platkin suggests getting more transparent (易懂的) labeling on packaging that describes exactly what the natural or artificial flavours are, so consumers are not misled into buying one product over another because of “natural flavours”. Reineccius also offers simple guidance: “Don’t buy anything because it says ‘natural flavours’. Buy it because you like it.”
1. Which is misunderstanding about the “natural flavour” juice according to Paragraph 1?
A. It comes from 100% original fruit.
B. It is nothing but advertising tricks.
C. It certainly contains extracts made in the lab.
D. It is absolutely safer than juice with artificial flavours.
2. What does the underlined word “exorbitant” in Paragraph 2 probably mean?
A. Popular. B. Expensive. C. Favorable. D. Innovative.
3. Why do companies use natural flavours in the products?
A. To cut the costs. B. To promote the sales.
C. To advocate a healthy diet. D. To avoid food safety issues.
4. What can we conclude from the text?
A. Gary and Platkin hold opposite perspectives.
B. Natural flavours are more environmentally friendly.
C. Customers are misled for ignoring labels on packaging.
D. Natural and artificial flavours are more alike than you think.
Passage 2
(2026·山东聊城·一模)
In the age of large language models (LLMs) and generative AI, we are witnessing an unprecedented transformation in how knowledge is produced, spread and consumed.
LLMs, we are told, make us more efficient, simplify complex work, automate boring tasks and allow us to focus on what matters. But as we feel surprised at their capabilities, a pressing concern emerges: Are these models genuinely boosting efficiency, or are they eroding our capacity for independent thought, judgment and critical reflection?
Efficiency is not a neutral term. The current narrative around generative AI treats efficiency as progress. It suggests that the faster something is done, the better. But faster is not always better. And not everything that can be automated should be.
The popular belief is that LLMs allow humans to assign repetitive work to machines and reserve their energy for more reflective tasks, but the opposite is often true. As the more intellectual labor — writing, summarizing and decision-making, for example — is handed over to AI, the less we will engage with it ourselves. Instead of reserving our thoughtfulness for higher tasks, we will increasingly lose the opportunities, and perhaps even the ability, to think critically.
So what do we really mean by “efficiency”? If it means shortening the time it takes to write a report, perhaps we have succeeded. But if it means replacing the intellectual effort that creates depth, coherence and reflection, then it’s not a gain; it’s a loss. The moment we accept LLMs as thought substitutes, rather than thought aids, we begin to worsen the very conditions under which human reasoning thrives: questioning, dialogue, uncertainty and contradiction.
There is no turning back the presence of LLMs in our lives. But we can choose how to live with them. The question is not whether they will think for us, but whether we will let them define what it means to think at all. Efficiency, in the true sense, should not be about doing more with less thought. It should be about doing better, with deeper attention, stronger ethics and sustained human insight.
1. What does the underlined word “eroding” in paragraph 2 mean?
A. Changing. B. Improving. C. Destroying. D. Expanding.
2. What do LLMs lead to, according to paragraph 4?
A. We get more reflective labor. B. We do independent thinking less.
C. We engage in more repetitive tasks. D. We reduce our work efficiency indeed.
3. What does the author advocate about our using LLMs?
A. Putting efficiency first. B. Reducing intellectual effort.
C. Achieving more with less time. D. Increasing human engagement.
4. What is the author’s purpose in writing the text?
A. To describe the fast development of LLMs.
B. To reflect on the negative effects of LLMs.
C. To question the necessity of pursuing efficiency.
D. To challenge the traditional definition of efficiency.
Passage 3
(2026·山东潍坊·一模)
In our fast-paced, stressful lives, we’re often turning to social media, online shopping, or gaming to escape daily pressures. However, the experience can often be the opposite, leaving us more exhausted. This begs the question: do we scroll because we’re stressed, or are we stressed because we scroll?
To better understand the subtle (微妙的) relationship of stress a and internet use, particularly how specific online behaviors influence stress levels. Belal’s team, from Finland’s Aalto University, conducted one of the first studies. They recorded real-world internet usage through tracking software installed on participants’ devices. Combined with a large sample size and a lengthy observation period, the findings offer especially valuable insight into bow online habits tie in with stress.
The study, published in the Journal of Medical Internet Research, collected internet usage data from around 1,500 adults over a seven-month period, comprising nearly 47 million web visits and 14 million app sessions. When compared with participants’ self-reported stress levels from questionnaires, researchers found a strong link between internet use and increased stress, particularly among those who already experienced daily stress. Women consistently reported higher stress levels than men, while stress tended to decrease with age and wealth. Not all online activities were equal, though. The study found that extended time spent on social media, online shopping, and gaming platforms was associated with higher stress levels compared to activities like checking emails or reading the news.
There are always concerns over internet life, especially increasing social media engagement, and some countries, such as Australia, banned social media for anyone under 16. The researchers hope that by gathering more detailed information about people’s internet habits, they can eventually develop concrete recommendations and tools that support healthier, more regulated online engagement. Juhi Kulshrestha, assistant professor at the Department of Computer Science, cautions against oversimplified solutions. She believes that blanket bans on internet use may overlook the emotional support certain online spaces provide. And it’s really crucial to study these issues further so the chicken and egg problem can be solved.
The research team plans to explore how different types of news — political, entertainment, or sports coverage — affect stress, helping further clarify the internet’s complex role in mental health.
1. Why did Belal’s team conduct their research?
A. To compare job-related stress levels.
B. To prove why internet use results in stress.
C. To create apps to help lower stress in adults.
D. To study how stress interacts with internet use.
2. What is a feature of the research method?
A. Focusing on a specific age group.
B. Conducting nationwide online interviews.
C. Collecting large-scale real data over time.
D. Using lab experiments to measure stress levels.
3. Which online activity likely causes the least stress according to the research?
A. Checking emails. B. Shopping.
C. Playing games. D. Chatting.
4. What does Juhi warn against?
A. Judging a book by its cover. B. Sacrificing tomorrow for today.
C. Painting everything with the same brush. D. Counting your chickens before they hatch.

Passage 1
(2026·山东淄博·一模)
Time is something we feel every day — rushing to school, glancing at watches, counting down minutes. Yet, surprisingly, modern physics struggles to explain why time moves forward at all. Einstein’s theory of relativity describes time as part of a fixed 4D spacetime, where past, present, and future coexist like pages in a book. Quantum mechanics (量子力学) does not naturally treats time as special — many processes could run backward just as well. So where does time’s flow come from?
A groundbreaking perspective was proposed in 1983 by scientists Page and Wootters. They proposed that time is an illusion (幻觉) created by quantum entanglement (纠缠). They envisioned the universe as a timeless quantum state. When one part acts as a “clock” and becomes entangled with the rest, time seems to emerge — just like page numbers help us read a story in order.
Experimental support is accumulating. In a 2024 study, scientists created a model using entangled quantum magnets and a spring. The entire system was static (静态的), yet the spring’s state changed over time relative to the clock, demonstrating how time might arise from entanglement.
But what could serve as the universe’s real clock? Italian physicist Paola Verrucci points to black holes. They are isolated, highly energetic, and — thanks to Hawking radiation — can entangle with the outside world. “It’s a perfect clock,” she says. “You can’t touch it, but you can be linked to it.”
More strikingly, Verrucci argues time’s direction may come from quantum measurement. Each time we observe reality, possibilities collapse into facts — a one-way process. “You create time,” she says, “when you ask what time it is.” This view transforms our role from passive witnesses of time to active participants. Time may not be a pre-existing river carrying us, but a story we co-write through our interactions with a quantum universe.
1. What can we know from paragraph 1?
A. The theory of relativity views time as independent of space.
B. Modern physics can explain why time moves forward easily.
C. Quantum mechanics specially focuses on the study of time.
D. Our understanding of time varies from physics perspectives.
2. Why did the scientists create the model?
A. To explain the quantum entanglement.
B. To support a timeless quantum state.
C. To show how time comes from entanglement.
D. To confirm time exists in a static universe.
3. Which viewpoint might Verrucci agree with?
A. Hawking radiation generated time. B. There is no ideal clock in universe.
C. Observing time helps to create time. D. Time existed as a river before humans.
4. What is the main purpose of the text?
A. To present the history of quantum mechanics.
B. To explore the origin of time from quantum links.
C. To compare a couple of known spacetime theories.
D. To illustrate technology of quantum entanglement.
Passage 2
(2026·山东临沂·一模)
Fifteen decades ago, Francis Galton first came up with the term “nature versus nurture”, and this debate over the factors shaping human identity has long been a central topic in human sciences. Do our genes determine our life paths, as hereditarians (遗传论者) argue? Or are we born as empty paper, shaped merely by the experiences we have in our families and the wider world? Today, however, a new branch of science is ready to overturn the debate. Through this new perspective, nature and nurture are hardly separable at all — genes and the environment do not act independently, but instead interact closely and even shape one another in tangible ways.
Genes do not shape our identities merely on their own within our bodies; instead, they function partly by molding the environments we choose or create. A striking finding of this research is that our environment is, in part, shaped by the genes of the people around us. Initial research suggests that your partner’s genes influence your likelihood of depression almost a third as much as your own genes do. A few students with a genetic trend for smoking in a high school seemed to cause smoking rates to skyrocket across the entire grade — even among students who have no direct contact with these students — like a gene-driven wildfire spreading through social networks.
Genes alone aren’t enough to determine these outcomes and neither is environment. Nature and nurture both shape each other, with nature influencing the way we experience nurture and nurture influencing the way our nature expresses itself. The more opportunities and information the environment provides — the more varied environments become — the bigger the role that genetic variation plays in distinguishing us into different groups.
Nature and nurture aren’t separate forces — they’re a Möbius strip (莫比乌斯环), endlessly circling back on each other. This interdependence means their interaction is fluid and reciprocal, a core insight of sociogenomics that bridges genetic and social science.
1. Why did the author mention the “nature versus nurture” debate in paragraph 1?
A. To emphasize the dominant role of family experiences.
B. To introduce a long-standing core topic in human sciences.
C. To highlight the weakness of early hereditarians’ arguments.
D. To lay a contrastive foundation for a new scientific perspective.
2. What can be inferred from the example of students?
A. Smoking behavior spreads mainly through direct persuasion.
B. Genetic tendencies can indirectly change group behavior.
C. School rules fail to control students’ genetic instincts.
D. Only smokers’ friends adopt the same genetic risks.
3. What happens when environments become more diverse according to paragraph 3?
A. People rely less on their genetic traits. B. Genetic differences play a smaller role.
C. Genetic differences become more influential. D. Nurture becomes more important than nature.
4. What does the author mean by comparing nature and nurture to a “Möbius strip”?
A. They depend entirely on physical conditions.
B. They have a one-way influence on each other.
C. They form a complex, continuous cycle of impact.
D. They are two separate parts of human development.
Passage 3
(2026·湖南师大附中·一模)
Plenty of previous research has shown that interacting with nature reduces stress, but it is not clear how long and how often the engagement needs to be. A new study published in the journal Frontiers in Psychology suggests that you don’t have to devote a full day, or even several hours to benefit from the contact with nature.
MaryCarol Hunter, the study’s lead author, and her colleagues recruited 36 residents of Michigan, almost all of whom were women and white. They instructed the participants to spend 10 minutes or more, at least three times a week, in an outdoor space where they could interact with nature.
In the hope of reflecting how people might realistically engage with nature as they go about their everyday lives, the researchers gave the participants permission to choose where and when they visited those outdoor spaces. The participants were also instructed to avoid accessing the Internet, taking phone calls, reading or engaging in conversations while they were there to minimize factors known to influence stress.
Every two weeks the participants collected saliva (唾液) samples before and after their nature experience. The researchers used those samples to measure levels of the stress hormone cortisol (皮质醇), a body chemical known to be related to stress.
The study found that the participants’ levels of cortisol dropped by an average of 21 percent after spending time in an urban green space. The effects were most pronounced when the nature experience was between 20 and 30 minutes long. Levels of the hormone dropped further when participants spent longer periods, but at a slower rate.
This study was quite small, and its participants were not diverse. Furthermore, it measured only drops in biomarkers for stress instead of direct impact on specific health outcomes. Still, the study’s findings are in line with a growing body of research that supports the idea that spending time in or living near a green space can have a positive effect on health and provides the first estimates of how nature experiences impact stress levels in the context of normal daily life.
1. What does Hunter’s study focus on?
A. The role of cortisol in stress reduction. B. The benefits of spending time outdoors.
C. The impact of nature on physical health. D. The ideal duration in nature for stress relief.
2. Why were the participants prohibited from certain activities in outdoor spaces?
A. To keep disturbing factors from affecting stress.
B. To test their ability to stay offline for a long time.
C. To reflect how people realistically engage with nature.
D. To encourage participants to focus on physical exercise.
3. What does the underlined word “pronounced” in paragraph 5 mean?
A. Direct. B. Lasting. C. Slight. D. Significant.
4. What does the author think of Hunter’s study?
A. Unreliable but novel. B. Specific and influential.
C. Limited but informative. D. Comprehensive and valid.

A reforestation revolution is being led by the innovative use of autonomous drones, a practice that balances deep respect for nature with cutting-edge technology. These drones, which work with high precision, are particularly effective in restoring large areas of forests damaged by wildfires and heavy logging. Reports show they can plant trees up to ten times faster than traditional methods, greatly boosting sustainability.
The core of this technology lies in the combination of AI and LiDAR (Light Detection and Ranging) remote sensing. The drones use LiDAR to scan damaged areas and measure the distance between the sensor and the ground. This system assesses key environmental factors such as soil composition, moisture levels and terrain contour, as well as potential risks like erosion and flooding. Then, onboard AI analyzes all these details carefully to precisely determine the best spots for planting native seeds.
Each drone carries hundreds of biodegradable capsules. These capsules contain not only seeds but also nutrients and fungi, which help the roots thrive in harsh conditions. After identifying ideal areas, the drones fire the capsules into the soil, covering an area as large as a soccer field in less than an hour. The fungi in the capsules enrich the soil, attracting insects and animals that enable forests to thrive. This effect is also crucial for carbon sequestration, which is the process of capturing and storing carbon dioxide to prevent it from warming the planet, and is an important part of the strategy against climate change.
Initial trials in wildfire-hit Kumamoto have achieved remarkable success, with an 80% germination (萌芽) rate, much higher than the 30 — 50% of manual methods. This success has drawn international attention: the US and the UK have adopted similar AI-led drones for reforestation in hard-to-access areas, showing great global promotion potential.
Despite the achievements, challenges remain. Scaling up the project requires huge investment and may face hurdles like airspace restrictions. Additionally, the technology needs to adapt to diverse ecosystems with varying soil and climate. However, these drones bring bright prospects for global sustainability, with potential applications in restoring biodiversity, rehabilitating coral reefs and reversing desertification, playing a positive role in global ecological protection.
1. What are the major advantages of the drone reforestation?
A. High accuracy and great efficiency.
B. Low expense and easy maintenance.
C. Long service lifespan and consistent updates.
D. All-weather adaptability and complete safety.
2. What is the main function of the fungus in the capsules?
A. To protect the seeds from being damaged.
B. To provide food for insects and animals.
C. To enhance root growth and soil health.
D. To help break the capsules into pieces.
3. How does the author present his ideas in paragraph 4?
A. By analyzing reasons and stating results.
B. By listing statistics and giving examples.
C. By giving a definition and making a contrast.
D. By making comparisons and quoting an expert.
4. What can be inferred about the technology according to the last paragraph?
A. It holds great promise despite present barriers.
B. It makes advances in large-scale application.
C. It can easily adapt to diverse ecosystems.
D. It removes restrictions to sustainability.

If the Amazon forest is to disappear, Altamira in Brazil is the town where that end could be foreseen. During the region’s development, a road was cut through the heart of the forest, marking an era of widespread destruction that remade the Amazon. Altamira thus became known in local media as the “champion of deforestation.”
Now Brazilian officials think this expansive town can also be the site of the forest’s rebirth. This year, the government set out to test a question that until now has largely been left to researchers: If left alone, can the Amazon forest restore itself? To test this assumption, officials closed off a degraded parcel of land and leased (租赁) it to a private carbon credit company to safeguard and restore. “Some of the tasks will be done by planting trees. But most of the restoration job will be left to Mother Nature. It’s called passive restoration. This is opening a new model that may be applied across the state,” said Governor Barbalho.
The search for solutions in the Amazon couldn’t be more urgent. Rates of deforestation have been dropping since the government made fighting environmental crime a priority, but the destruction hasn’t stopped. Nearly 6,300 square kilometers were lost last year, bringing the ecosystem closer to what scientists warn is a tipping point, when the Amazon is no longer able to maintain its own rainy ecosystem. Evidence of its arrival is springing up: dried riverbeds, forest fires, punishing droughts, and increased tree death. Scientists have predicted the forest could experience a broad ecological collapse by 2050, when 10 — 47% of it will be exposed to various disturbances that could activate unexpected ecosystem changes.
But other research has also provided cause for hope. Despite the delicate nature of the Amazon’s ecosystem, the forest has also demonstrated a remarkable capacity for recovery. A recent study showed that roughly 72,000 square kilometers of destroyed forest are already in an advanced stage of natural recovery.
1. What do we know about Altamira from paragraph 1?
A. It reshaped the Amazon area. B. It saw the rebirth of the forest.
C. It benefited from the new road. D. It headed the forest destruction.
2. What is the core belief behind passive restoration?
A. Nature knows the right way. B. Companies make better guardians.
C. Tree-planting is a quicker fix. D. A hands-off government is the key.
3. What makes it critical to restore the Amazon rainforest?
A. Deforestation rates are ever-rising. B. The rainy ecosystem has collapsed.
C. A point of no return is approaching. D. Spring has brought lots of disasters.
4. What is the best title for the text?
A. Can Private Companies Help? B. Can Passive Restoration Last?
C. Can Altamira Stop Deforestation? D. Can Amazon Avoid Disappearing?

(2026·山东济宁·一模)
Chaotan One, the world’s first commercial power generator that uses supercritical carbon dioxide (sCO₂), has begun operations in China. This achievement breaks a century-old tradition of using steam for power generation, marking a major improvement in efficiency.
The invention of the steam engine was a first step towards the Industrial Revolution that changed the world. Over the years, the engine’s efficiency was further improved through different designs and fuels; however, the medium for doing work remained the same — steam.
Scientists seeking further improvements in power efficiency noticed that a significant portion of energy is wasted generating steam to drive turbines (涡轮机). Water needs to be boiled first and needs to undergo a phase change to generate steam. Scientists have been looking for a better medium to replace steam.
They found this in sCO₂. CO₂ exists as a gas at room temperature and can be cooled to form dry ice by reducing pressure and lowering temperature. When temperature is raised to 31°C, and pressure is increased to 7.37 MPa, CO₂ enters its supercritical state, where it exhibits properties of both a liquid and a gas. In applications such as moving a turbine, this is extremely useful since the gas-like state offers less resistance while the liquid-like state provides greater push power.
The power generation process works like this: The CO₂ is first pressurized into a supercritical state. Then the sCO₂ passes through a heat exchanger, absorbing heat from an external heat source, and its temperature rises to 400 — 600℃ with a substantial increase in internal energy. After that, it enters a turbine and expands rapidly, driving it to move at a high speed and transforming thermal (热的) energy into mechanical energy, which is then further turned into electrical energy for output. The CO₂ remains in a supercritical state throughout the entire process, with no phase change loss.
The success of the Chaotan One will likely start a new era in power generation, using CO₂ as a medium and bypassing the need to transform water into steam.
1. What does the author intend to do in paragraph 2?
A. Highlight the value of steam. B. Applaud the past contributions.
C. Outline the Industrial Revolution. D. State the background of a new discovery.
2. What is the biggest problem with steam power generation?
A. Energy-intensive. B. Labor-demanding.
C. Noise-producing. D. Money-consuming.
3. What plays a key role in the high efficiency of Chaotan One?
A. The durability of turbines.
B. The quick commercialization of generators.
C. The easy availability of CO₂.
D. The continuity of CO₂’s supercritical state.
4. What can be a suitable title for the text?
A. Unpredictable Changes of CO₂ B. Polarized Views on Chaotan One
C. A Pioneering sCO₂ Power Generator D. A Breakthrough in Steam Engine

Passage 1
(2026·广东梅州·一模)
For generations, sharing a bed has been widely seen as a key sign of closeness for couples. But a quiet shift is taking place in some Western countries. The trend, called “sleep divorce,” is not about ending a relationship. Instead, it means partners choose to sleep in separate beds or even separate rooms to improve their sleep quality.
Sleep divorce is a practical response to common sleep problems, such as snoring, different bedtimes, disagreements over room temperature, shift work, and so on. And stress-related sleeplessness are among the main reasons couples consider sleeping apart. Importantly, this choice is not a legal separation nor a sign of marriage trouble.
Several forces are driving this trend. First, sleep troubles are rising worldwide, linked to noise, stress, and late-night screen time in modern life. Second, snoring affects up to half of adults, far more than many realize. Third, health is becoming a higher priority than tradition; couples now see good sleep as essential to well-being, just like diet and exercise. Finally, younger generations are redefining relationship success, valuing flexibility over fixed rules about how couples “should” sleep.
Interestingly, sleeping separately often brings couples closer. With better rest, they report fewer arguments, better moods, and clearer communication. Poor sleep can make people easily annoyed and less empathetic, while solid rest supports emotional strength.
Experts note that sleep divorce is helpful when partners feel bitter due to constant sleep interruption, wake up tired despite enough time in bed, or deal with heavy snoring. But it can backfire if it’s used to avoid dealing with relationship conflicts, if one partner feels lonely or rejected, or if the decision is not mutual. Therapists advise couples to talk about it as a health choice for both people, not as a way to escape each other. As health and relationship satisfaction take priority over old expectations, sleeping apart may become a normal option for more couples in the future.
1. What is “sleep divorce” according to the text?
A. A legal step to end a marriage. B. A sleep arrangement to improve rest.
C. A solution mainly for shift workers. D. A trend of avoiding emotional connection.
2. What does the word “backfire” in paragraph 5 probably mean?
A. Improve quickly. B. Gain popularity.
C. Succeed unexpectedly. D. Cause harm instead.
3. What can be inferred about younger generations in paragraph 3?
A. They stick to traditional sleep habits. B. They experience fewer sleep problems.
C. They value health less than older couples. D. They are more flexible in defining relationships.
4. Which of the following is the best title for the text?
A. Why couples Choose to Sleep Apart. B. Get a Divorce: For a Better Sleep
C. The Science Behind Better Sleep. D. How to Design a Dual-Bedroom Home.
【答案】1. B 2. D 3. D 4. A
【解析】
【导语】本文是一篇说明文。主要介绍在一些西方国家出现“睡眠离婚”的趋势,即伴侣为提高睡眠质量选择分床或分房睡,阐述了这一趋势出现的原因、带来的影响以及专家的相关建议。
【1题详解】
细节理解题。根据第一段中的“The trend, called “sleep divorce,” is not about ending a relationship. Instead, it means partners choose to sleep in separate beds or even separate rooms to improve their sleep quality.(这种被称为 “睡眠离婚”的趋势,并非意味着要结束一段感情。相反,它指的是伴侣们为了改善睡眠质量,选择分床而睡,甚至分房而睡)”可知,“睡眠离婚”是一种为改善休息的睡眠安排,故选B项。
【2题详解】
词义猜测题。根据第五段中的“But it can backfire if it’s used to avoid dealing with relationship conflicts, if one partner feels lonely or rejected, or if the decision is not mutual.(但如果它被用来避免处理关系冲突,如果一方感到孤独或被拒绝,或者如果这个决定不是双方共同做出的,它可能会backfire)”可知,这些情况是负面的,会让“睡眠离婚”产生不好的结果,所以“backfire”意思可能是“产生反效果,造成伤害”,与“Cause harm instead.”意思相符,故选D项。
【3题详解】
推理判断题。根据第三段中的“Finally, younger generations are redefining relationship success, valuing flexibility over fixed rules about how couples “should” sleep.(最后,年轻一代正在重新定义关系的成功,比起关于夫妻“应该”如何睡觉的固定规则,他们更看重灵活性)”可知,年轻一代在定义关系方面更灵活,故选D项。
【4题详解】

(2026·湖南衡阳·一模)
Despite decades of messaging from litter prevention campaigns, trash still finds its way onto streets. A Portland-based organization has been inspiring residents to clean up their neighborhoods, one block at a time. Since 2020, Adopt One Block has helped over 7,000 people become Block Ambassadors. These volunteers beautify and maintain over 8,500 blocks in Washington and Oregon.
Sarah Yapp adopted her block in south Eugene. With cars rushing by, she explained why. “When I was growing up, my dad actually made me pick up trash on the street. That was the era of McDonald’s Styrofoam (泡沫塑料) containers, when people just threw them out of their windows. So, I used to hate that,” she said. “And then I grew up, and I realized I don’t like trash on the street as an adult either.” “Oh, I got something!” Yapp used her grabber to pick up a paper cup from a bush and dropped it in a bag.
Olivia Langley is Director of Operations for Adopt One Block. “We send you free clean - up supplies,” she said. “That’s everything from a bucket, a trash grabber, trash bags, to gloves.” Block Ambassadors set their own schedules for trash grabbing and can access additional resources from the organization to deal with different “trash encounters”. Langley said that when necessary, medical sharps containers are also provided.
However, Langley insisted that volunteers should only do the amount of clean-up they are comfortable with. Things like broken glass, thrown - away needles and perilous materials can be handled by municipal agencies, she said.
Sarah Yapp shared the idea with her friend Rachel Sanders and now they both pick up trash on their own blocks and beyond. The friends said the garbage can sometimes be messy, but they both find fulfillment in cleaning it up. “Here we are picking up trash and there are people cheering us on and joining in. Some even adopt their own neighborhoods!” Yapp said. “The other day, a middle school student saw me on my block and asked, ‘Are you picking up trash? Thank you!’”
1. What made Sarah Yapp become a Block Ambassador?
A. Her father’s personal request.
B. The increase in McDonald’s products.
C. The technical support from the non - profit.
D. Her own appreciation of a clean environment.
2. What do we know about Block Ambassadors’ work according to Olivia Langley?
A. They follow a very tight schedule.
B. They handle various kinds of trash.
C. They have good medical insurance.
D. They protect their blocks from danger.
3. What does the underlined word “perilous” in paragraph 4 mean?
A. Dangerous. B. Simple.
C. Unwanted. D. Unclean.
4. What does the last paragraph mainly talk about?
A. The positive impact of Sarah’s work.
B. The financial value of Sarah’s efforts.
C. The friendship between Sarah and Rachel.
D. The personal satisfaction from volunteering.

Passage 3
(2026·河北承德·一模)
A few weeks ago, an article by Nathan Heller in The New Yorker indicated “the end of the English major”, examining the trend of declining English department nationwide and the cultural factors that lead students away from spending four years with the passion for Dickens and Shakespeare. Like every other humanities-lover on a college campus that day, I was swept away in the mass panic. My major was, according to a reputable English-major-loved publication, dead.
Heller focused on Arizona State University (ASU) and Harvard University, large “indicators”(higher education. I initially thought he ignored small liberal arts (文科) colleges, assuming English major were safe at Allegheny College, where students supposedly came for the love of learning, not for middle management when they graduate. But data ruined this hope: Allegheny had 84 English majors (9% of all majors) in the spring semester of 2003, but just 20 (2.5%) now — a 72% drop in about 20 years matching the national trend.
Allegheny’s website fuels optimism, asking, “Why put your mind to just one thing?” and define itself as a “safe place of learning”, unlike ASU, which sees degrees as career stepping stones, or Harvard where, according to Heller, even an “unusual major” finds work. Yet campus reality in Allegheny differs Students get locked into majors early, “mind over major” loses to closed-off departments, and English majors fear unemployment, thinking they wasted time and money.
We need to reject the campus “disease”, Heller noted — pressuring students to choose “safeguard paths and dismissing humanities as “hobby-based”. The well-known author Kurt Vonnegut reminded you that the arts may not be the best way to “make a living” but “make life more bearable” and “make soul grow”. Not everybody can or should pursue a degree in chemistry, but it is increasingly clear to me that everybody would benefit from spending 20 credit hours reading, thinking about and discussing literature. While English majors may decline, their lessons live on. As the novelist Jonathan Lethem wrote, “Time change and men adapt.” Between “too bad” and “worst”, we can do better.
1. What phenomenon did Heller point out about English literature?
A. Students’ fading love for it. B. Its limited research visions.
C. Students’ confusion about it. D. Its declining literary works.
2. Why did the author’s hope for Allegheny College fade?
A. It closed most liberal arts majors. B. It valued career training more.
C. It admitted fewer English majors. D. It cared less about students’ likes.
3. What can be inferred from Allegheny’s website?
A. It tried to learn from Harvard. B. It didn’t match its real situation.
C. It failed to ensure students’ safety. D. It didn’t promote critical thinking.
4. What does the author advocate in the last paragraph?
A. Students should plan a unique life journey. B. Schools must make English more inviting.
C. Students need to stick to their own purposes. D. Schools ought to look beyond practical values.
【答案】1. A 2. C 3. B 4. D

Passage 4
(2026·山东菏泽·一模)
Ethics (伦理) in Cybersecurity by Marquez, a former cybersecurity analyst for a global tech firm, is a timely exploration of the moral dilemmas that define modern digital life.
The book is organized around six “ethical crossroads”, each illustrated with a detailed case study. One of the most striking chapters focuses on the 2025 “SecureData” case, where a major tech company discovered weakness in its popular messaging app — one that could expose users’ private conversations. The company faced a choice: tell users the problem immediately or fix it quietly over six months. Marquez walks readers through the arguments on both sides: the “duty to protect users” versus the “duty to avoid bad reputation”. She doesn’t offer a simple answer — instead, she teaches readers to weigh conflicting values, a skill she calls “ethical reasoning for the digital age”.
Marquez also challenges common myths about cybersecurity ethics. She argues against the idea that “the end justifies the means” when it comes to fighting cybercrime, citing a 2024 case where a government accessed a criminal group’s servers to recover stolen data, but in doing so, accidentally obtained the private emails of 10,000 innocent people. “Security without ethics isn’t security — it’s just control,” she writes. This focus on balancing security and ethics makes the book stand out in a field often dominated by technical solutions.
Marquez’s engaging style makes the book accessible. She, for instance, compares a company’s decision to hide a software problem to “a teacher knowing a classroom door is broken but not fixing it because he doesn’t want to stop class.” She also includes “Ethical Checklists” at the end of each chapter, which guide readers to apply the book’s lessons to their own lives, for example, should you report a friend who shares your password with others?
Overall, Ethics in Cybersecurity is more than a book — it’s a tool for thinking critically about daily digital choices. As Marquez puts it: “In cyberspace, every click is a choice — and every choice has an ethical cost.”
1. What can be inferred from the 2025 “SecureData” case?
A. Companies prioritize user privacy. B. User data is hard to protect.
C. Cyber ethics involves tough choices. D. Messaging apps are easy to access.
2. Which of the following is Marques probably against according to paragraph 3?
A. Download papers on the CNKI. B. Polish an article by DeepSeek App.
C. Give a thump-up on a friend’s Moments. D. Disclose a friend’s address on the internet.
3. What is a feature of Ethics in Cybersecurity according to the text?
A. It is packed with complex theories. B. It provides step-by-step instructions.
C. It is intended for cyber professionals. D. It adopts a down-to-earth writing style.
4. What is the author’s purpose in writing the text?
A. To publicize cybercrime prevention. B. To honor a talented technical expert.
C. To introduce a book on Cybersecurity. D. To recommend an essay on digital life.
【答案】1. C 2. D 3. D 4. C
【解析】

Passage 1
(2026·河北石家庄·一模)
Many environmental and behavioral factors can affect the body’s internal clocks, which control various body functions. However, modern life can throw off these biological times, increasing our sensitivity to different conditions. Light, a major factor affecting the body’s internal clocks, has long been linked to various health impacts. This is evidenced in populations like shift workers, who face a higher risk of heart disease due to night-time light exposure.
Previous studies that used satellite data found associations between people living in bright, urban areas and heart disease, but they only measured outdoor light at night. Daniel Windred at Flinders University and his colleagues wanted to know whether an individual’s overall light exposure was associated with heart problems.
They tracked about 89, 000 people without heart disease who wore light sensors for one week between 2013 and 2016, which is the biggest study of personal light exposure patterns and heart health to date. The sensors recorded any natural or artificial light from their environment, including that from phones. Over years, those with the brightest nights had a higher risk of developing heart disease than those with dark nights. One representative case in the highest light exposure group would be someone who turned on overhead lights for an hour between midnight and 6 am. “This means they have among the highest night light exposure — within the top 10% of all participants,” says Windred. He adds that the body continues to react to an artificial light after it has been turned off, and even short exposures can have an effect.
The researchers controlled for factors like gender, age, smoking, and shift work. They also showed that the association between light exposure and heart disease risk was independent of sleep duration or quality, pointing to night light exposure as the key driver of the results.
“The importance of these observations cannot be underestimated,” says Martin Young at the University of Alabama at Birmingham. “With the coming of a society that operates around the clock, disturbing our biological clock systems has become more and more common. This study highlights the significant health dangers associated with exposure to light at the wrong time.”
1. How are the health impacts of light exposure presented in the first paragraph?
A. By providing data. B. By citing a document.
C. By giving an example. D. By making an assumption.
2. What does paragraph 2 stress about previous studies?
A. Their limitation. B. Their goal.
C. Their uniqueness. D. Their process.
3. Why is the case in paragraph 3 mentioned?
A. To applaud a research method. B. To clarify a study classification.
C. To define a cause of heart disease. D. To describe a common sleep habit.
4. What is Martin Young’s attitude to the research findings?
A. Supportive. B. Cautious. C. Picky. D. Anxious.
【答案】1. C 2. A 3. B 4. A

Passage 2
(2026·河北盐山·一模)
Jim Thorpe is one of the greatest athletes of all time. He had amazing athletic abilities and was well-known during his lifetime, yet that did not make Thorpe a stranger to adversity.
Thorpe was an American Indian from Oklahoma who developed his extraordinary athletic skills in his youth through hard labor. It was also in his youth that he learned to endure hardship brought upon by racial prejudice. Many would say his childhood was not easy. He grew up poor and at age 9 his twin brother passed away and a few years later he lost both of his parents.
But that did not stop him from doing what he loved and pursuing his dreams. Nothing seemed to stop him, not even stolen shoes. Just hours before Thorpe was going to compete in the 1912 Olympics, somebody stole his shoes. Thorpe improvised (临时拼凑) by getting shoes out of the garbage. The shoes were two different sizes. He wore an extra pair of socks on one foot to even them out.
He still went on to win two gold medals—winning each event he competed in except for one, the javelin (标枪). The javelin was the only event he didn’t win, probably because he had never competed in that event before. It is interesting to note that Thorpe had tried to throw the javelin once before in the Olympic trials. At the time, he didn’t know that he could throw it with a running start. He threw it standing still and was placed second.
At the Olympics,he also took part in the decathlon (十项全能运动). He finished first in two events, third in four events, and fourth in two more. Thorpe ended up finishing third in the world. He was undoubtedly a dominating force that couldn’t be stopped and just kept on going.
I think Paul Dughi said it best, “It’s hard to imagine now that pro athletes get paid millions of dollars just to wear a particular brand of shoes. For Jim Thorpe, it didn’t matter what kind he wore.”
1. What does the underlined sentence in Paragraph 1 mean?
A. The adversity Thorpe met with led to his success.
B. Thorpe’s success was no guarantee of a better life.
C. Thorpe’s career brought him both gains and losses.
D. Thorpe suffered many hardships despite his success.
2. Why did Thorpe wear more socks on one foot?
A. To prevent the foot from injury. B. To make the shoe fit the foot.
C. To stop the shoe from being stolen. D. To show his problem-solving skills.
3. What most likely led to Thorpe’s failure to win the javelin?
A. Loss of his own sports shoes. B. A casual attitude towards the event.
C. Lack of experience in the event. D. A shortage of talent for the event.
4. Which of the following words can best describe Jim Thorpe?
A. Loyal and enthusiastic. B. Genuine and creative.
C. Tough and strong-minded. D. Selfless and good-tempered.
【答案】1. D 2. B 3. C 4. C

Passage 3
(2026·山东德州·一模)
You’ve followed all sleep experts’ advice — going to bed on time, avoiding afternoon coffee, and keeping your bedroom cool as you like, dark with no light on, and quiet as possible — yet you still toss and turn. Glancing at the silver light through the curtains, you wonder: Could the full moon be ruining your sleep?
Figuring out the moon’s impact on human sleep is challenging, as emotions and expectations often cloud judgments. Many people romanticize full moons, especially special events like harvest or blue moons, while others anticipate restlessness under a full moon, which alone can disrupt sleep. Scientific studies suggest real physiological effects caused by the moon.
In a 2013 study, Swiss researchers analyzed data from an experiment in which participants had no idea their sleep was being studied for lunar effects. Around the full moon, participants experienced a 30 percent drop in deep-sleep brain activity, took 5 minutes longer to fall asleep, and slept 20 minutes less overall. They also reported worse sleep quality and had lower levels of melatonin, the hormone (荷尔蒙) that your body releases naturally at night to calm your body down and prepare you for sleep. However, all these studies share one major limitation: they were conducted in sleep laboratories, where the subjects may be disturbed easily by the unfamiliar setting.
To address this, University of Washington researchers tracked sleep in real-world environments: three Argentinian communities (urban suburbs, rural village with limited electricity, remote area with no electricity) and 464 Seattle university students. Across all groups, regardless of artificial light access, participants slept less and took longer to fall asleep in the nights leading up to a full moon. The researchers think this may reflect an ancient adaptation: When the moon was brightest, our ancestors likely stayed up later to hunt, socialize, or work by natural light.
The sleep changes were most obvious in low-electricity communities, where moonlight remained the main light source at night. Sleep experts note that while the full moon’s effect, up to one hour less sleep, is profound, artificial light from screens likely has an even greater impact on modern sleep.
1. What is the difficulty in studying the moon’s effect on sleep?
A. People’s habits and hobbies. B. Health conditions and sleep space.
C. Artificial light or noise in the room. D. People’s emotions and anticipations.
2. What did the 2013 Swiss study find about full moons?
A. They caused 25 minutes less sleep on average.
B. They affected people more in the real world.
C. They had less impact on sleep than expected.
D. They led to a reduced deep-sleep brain activity.
3. Why did University of Washington researchers adjust study surroundings?
A. To compare sleep patterns by age group.
B. To analyze the influence of artificial light on sleep.
C. To avoid the impact of strange settings on subjects.
D. To test whether urban lifestyle cancels lunar effects.
4. Which would be the best title for this passage?
A. The End of Moonlight Folktales B. City Lights’ effects on Human Sleep
C. Moonlight’s battle with artificial light D. The Moon’s Silent Theft of Our Sleep
【答案】1. D 2. D 3. C 4. D

Passage 4
(2026·山东青岛·一模)
I first encountered the classics at 19, when I studied English literature at university. But a lack of life experience, combined with exams, essay deadlines and an obsession (痴迷) with good grades, left me little time to truly concentrate on them – Middlemarch, The Picture of Dorian Gray, Pride and Prejudice, Madame Bovary etc. I loved these books, yet I never got the chance to deeply engage with them.
Some 40 years later, as an editor, it’s now my job to figure out what makes a book tick or more often, what it needs to make it tick. So, when a coworker suggested we deconstruct classics to find their “secret to lasting appeal”, I was intrigued. I decided to reread Middlemarch, which I had loved before but never fully grasped. I did hesitate a bit, though; could I, with my attention constantly distracted by technology, handle its 900 pages of tiny print?
Not wanting to hold back entirely, I tried the audiobook instead. The audio’s vivid delivery certainly drew me in, but what truly took me aback was the new understanding that came with age. Themes that felt distant at 19 came into sharp focus at 60: ideas of marriage, ambition, and unmet expectations that had flown over my younger head now echoed (回响) deeply within me. I also noticed striking similarities in other classic characters: Emma’s desire for an “ideal life” in Madame Bovary mirrors the social comparison we see on social media today, and Dorian Gray’s obsession with youth in The Picture of Dorian Gray reflects our selfie-obsessed culture.
Then came the real work: taking them apart to see why they’re classics. Some were easy to analyze, others tricky, but we gave them the attention they deserved – more than I ever could at 19. What struck me most was that classics last not for their age, but for capturing universal human truths: desires, fears, and hopes that never fade. Rereading them isn’t just about revisiting old tales; it reconnects us to our unchanging human nature, enriches our understanding of time, and grows with us as we do.
1. What does the author imply about the classics in paragraph 1?
A. They enriched his experience.
B. They proved too difficult for him.
C. They made for his academic success.
D. They failed to obtain his full appreciation.
2. What does the underlined word “intrigued” in paragraph 2 mean?
A. Hesitant. B. Interested. C. Fulfilled. D. Puzzled.
3. Why does the author mention Emma and Dorian Gray?
A. To show classics’ modern relevance.
B. To criticize current social problems.
C. To present impressive analytical skills.
D. To highlight their lasting popularity.
4. What can be a suitable title for the text?

Passage 1
(2026·广东汕头·一模)
A wildfire burns in the hills of a Los Angeles suburb, leaping from one dry bush to another. As it approaches the first house, the plants around it catch fire, but the house itself stubbornly refuses to do so: any small flames along its walls quickly die out. There’s no water in sight — the flames are put out by sound waves.
This scene is not science fiction. Engineers at an American tech company built a device using low-frequency sound waves to fight fires. “It’s basically vibrating (震动) the oxygen faster than the fuel can use it, blocking the chemical reaction,” explains Geoff Bruder, an aerospace engineer who once studied heat engines for NASA.
Fire needs heat, fuel and oxygen; taking one of these away will stop the fire. Sound waves push oxygen away from the fuel, preventing the fire getting the air it needs to continue its burning. The company has demonstrated a fire control from as far as 25 feet away.
Using sound against fire isn’t new. A U. S. defense research agency studied it over a decade ago. However, a major challenge is to scale up the technology without creating loud or even damaging sound effects.
The company overcame this by using infrasound — sound waves at 20 hertz (赫兹) or lower, which humans cannot hear. These waves also travel farther than higher-frequency sounds. The device looks like a metal box attached to the roof. When heat sensors detect a flame, an electric motor drives a piston (活塞) to create infrasound, which travels through metal tubes on the roof, creating a “force field” to put out the fire and prevent the building catching another fire.
Experts note that while sound waves can effectively influence fire, they currently work best on smaller flames. Nevertheless, homeowners and large energy companies are game to give it a try: The company is working with two California power suppliers and plans to install fifty pilot units early in 2026.
1. What does the passage begin with?
A. A historical review. B. A personal anecdote.
C. A scientific explanation. D. A descriptive situation.
2. What is the basic principle behind sound-based firefighting?
A. It removes the burning material. B. It cools the fire with vibrations.
C. It separates oxygen from the fuel. D. It blocks the heat with natural force.
3. What is a key feature of infrasound?
A. It is silent to human ear. B. It is of high-frequency.
C. It travels at a fast speed. D. It requires loud volumes.
4. What does “game” in paragraph 6 most likely mean?
A. Pleased. B. Ready. C. Afraid. D. Unwilling.
【答案】1. D 2. C 3. A 4. B

Passage 2
(2026·湖北襄阳·一模)
Penguins are some of the world’s most familiar and beloved birds, but southern rockhoppers are the tough guys of the penguin world. Their fondness for colonies (聚居地) high over thousands of feet separates them from the other penguin species that prefer soft, level ground in the Falklands.
One evening, I struggle to keep up with some scientists as they march through thick grass in the Falklands. They are looking for rockhoppers that have pencil-case-size black boxes taped to their backs and collecting those boxes, which contain GPS data loggers (记录仪). Some also track diving and heart-rate information. Later, in the scientists’ field station, we gather around a computer screen, analyzing the collected data, which will give us a critical read on ocean conditions, revealed by the birds’ responses.
With a lifespan of 10 to 15 years, the species can withstand the occasional disaster and rebuild their population over time. But as colonies damaged by human activities struggle to recover, a string of disasters has knocked them down. Despite their bravery, rockhoppers are highly sensitive. Research by these scientists shows that even a small increase in sea temperature can affect the birds’ food supply and lower chick and adult survival. Besides, changing weather is causing unseasonably intense storms, killing chicks who haven’t yet grown their thick, waterproof feathers.
However, moving to cooler water isn’t an option. The constant winds there would push the little penguins into the icy coasts of Antarctica, and there’s no land where they could build new colonies. These scientists are trying to re-establish the native grass. “It may be impossible to stop the changes sweeping their ocean habitats,” Quillfeldt, a seabird ecologist says. “But to help them on land, at the breeding (繁殖) sites, is something we can actually do.”
Thinking of the young rockhopper leaping over a fearful gap, I ask the scientists: Can rockhoppers’ courage be an advantage for their survival? Quillfeldt feels it may. Curiosity and bravery can encourage seabirds to find ways to adapt. Don’t forget they’ve got attitude.
1. What is the function of the black boxes on the rockhoppers’ backs?
A. To locate GPS data loggers. B. To distinguish birds’ responses.
C. To analyze the survival rate. D. To record data about ocean conditions.
2. What may bring a challenge to rockhoppers’ population?
A. Their lengthy lifespan. B. Their fondness for high rocks.
C. Their thick waterproof feathers. D. Their sensitivity to the climate change.
3. What could be a practical way to help rockhoppers according to paragraph 4?
A. Establish new colonies. B. Improve the breeding sites.
C. Stop the environmental changes. D. Move to the coasts of Antarctica.
4. What is the author’s attitude toward rockhoppers’ future?
A. Hopeful. B. Reserved. C. Dismissive. D. Doubtful.

【3题详解】
细节理解题。根据第四段中““It may be impossible to stop the changes sweeping their ocean habitats,” Quillfeldt, a seabird ecologist says. “But to help them on land, at the breeding (繁殖) sites, is something we can actually do.”(“或许无法阻止席卷它们海洋栖息地的变化,”海洋鸟类生态学家Quillfeldt说道,“但在陆地上,在繁殖地帮助它们,这是我们实际上能够做到的事情。”)”可知,可做的实际行动是改善企鹅的繁殖地点,故选B。
【4题详解】
推理判断题。根据最后一段中“Curiosity and bravery can encourage seabirds to find ways to adapt. Don’t forget they’ve got attitude.(好奇心和勇气能够激励海鸟寻找适应的方法。别忘了它们还有态度)”可知,跳岩企鹅的勇气和好奇心可以鼓励它们找到适应环境的方法,故作者对它们的未来是充满希望的,故选A。
Passage 3
(2026·山东日照·一模)
Half the world’s 100 largest cities are experiencing high levels of water stress, with 38 of these sitting in regions of “extremely high water stress”, new analysis and mapping has shown.
Water stress means that withdrawals for public water supply and industry are close to exceeding available supplies, often caused by ineffective regulation of water resources and intensified by climate breakdown. Watershed Investigations and the Guardian mapped cities on stressed catchments revealing that Beijing, New York, Los Angeles, and Delhi are among those facing extreme stress, while London, Bangkok and Jakarta are classed as being highly stressed.
Separate analysis of NASA satellite data shows which of the largest 100 cities have been drying or getting wetter over two decades with places such as Chennai, Tehran and Zhengzhou showing strong drying trends and Tokyo, Lagos and Kampala showing strong wetting trends. Most of the city regions in notably wetting zones are in sub-Saharan Africa, with just Tokyo and Santo Domingo in the Dominican Republic sitting elsewhere. Most of the urban centers in areas with the strongest drying signals are across Asia, particularly northern India and Pakistan.
Now in its sixth year of drought, Tehran is critically close to “day zero” when no water will be available for its citizens, and last year the president, Masoud Pezeshkian, said the city may have to be relocated if the drought continues. Mohammad Shamsuddoha, professor of water crisis and risk reduction at UCL, said, “By tracking changes in total water storage from space, Grace, the NASA project, shows which cities are drying and which are getting wetter, offering an early warning of emerging water insecurity.”
Last week the UN announced the world had entered a state of serious water shortage where degradation of some resources had become irreversible (不可逆的). The World Bank Group has also been sounding the alarm. Global freshwater reserves have decreased sharply over the past 20 years, according to the group.
1. What does the author think leads to water stress?
A. Heavy water pollution. B. Poor water management.
C. Freezing climate. D. Large population.
2. What does NASA satellite data indicate?
A. Huge water loss. B. Severe water shortage.
C. Changeable rainfall. D. Uneven water distribution.
3. What is the purpose of Grace?
A. To control water use. B. To increase freshwater reserves.
C. To issue an alert in time. D. To slow down the drying trends.
4. What is the text mainly about?
A. The falling water storage across the world. B. The problems with global water regulation.
C. NASA’s efforts to track global water changes. D. Growing water risks faced by big cities worldwide.

Passage 4
(2026·河南濮阳·一模)
A study, published on November 6 in Science, identifies a specific biological “timer” that controls when a seed decides to “wake up” and grow, which could help protect the global food supply from the unpredictable effects of climate change.
The research involved scientists from top institutes in China, Denmark, France, and the United Kingdom, focusing on seed dormancy (休眠) — a natural state of sleep that prevents seeds from sprouting (发芽) even when environmental conditions appear favorable. While this helps plants survive in the wild, it creates what researcher Wang Yucheng calls a “double-edged sword” for modern agriculture.
Wang Yucheng, a professor at the Institute of Tibetan Plateau (高原) Research of the Chinese Academy of Sciences, explained that if seeds woke up too early, they might sprout while still attached to the plant before harvest. This ruins the quality of the grain and leads to more than $1 billion in losses annually. Contrarily, if the seeds stay asleep too long, they will not grow in time for the next planting season, throwing the entire farming schedule off.
Using advanced DNA mapping technology, the team identified the MKK3 gene as the master regulator of seed dormancy. Christoph Dockter explained that the gene’s copy number and activity determined dormancy length — more copies shortened dormancy.
The study highlighted a unique variety of qingke, found on the Qinghai-Tibet Plateau. Qingke’s unique MKK3 activity offers a natural solution to seed dormancy in cold regions. This variety has evolved what can be described as the world’s “highest-activity mode”. Through long-term selection and breeding, qingke has developed one of the strongest MKK3 activities globally, resulting in the weakest seed dormancy and the stronger sprouting capacity.
To adapt to the plateau’s extreme harvest-time cold, locals harvest immature grains and use post harvest treatments like air-drying and roasting for storage.
Wang stated the discovery offered a blueprint for “designing” stress-resistant crops. With climate changing, lost or weakened ancient genetic characteristics may regain value, and future research will try to recover these characteristics to improve modern crops.
1. What is the advantage of seed dormancy?
A. Help wild plants survive naturally. B. Improve grain quality effectively.
C. Shorten the growth cycle of plants. D. Adjust farming schedules perfectly.
2. What does the author try to illustrate by mentioning qingke?
A. Its sprouting ability. B. Its massive output.
C. Its unique gene activity. D. Its period of dormancy.
3. What can be inferred from the passage about future agricultural research?
A. It will focus on artificial editing of the MKK3 gene.
B. It may use old genetic features for climate-resistant crops.
C. It will explore ancient genetic characteristics of more crops.
D. It may attempt to completely remove dormancy in crops.
4. What can be a suitable title for the text?
A. The Sleep of Seeds: How Dormancy Costs Agriculture Billions
B. Caution: Climate Change and Its Impact upon Global Food Supply
C. The MKK3 Gene: A Genetic Key to Controlling Crop Growth Speed
D. Designing Future Crops: How a Seed “Timer” Could Secure Our Food

Passage 1
(2026·山东青州·一模)
Pick up any packaged processed food, and there’s a decent chance that one of its listed ingredients will be “natural flavour”. The ingredient sounds good, particularly in contrast to “artificial flavours” since there is a common belief that ingredients from nature are necessarily safer than something artificially made. But it’s not true. Then what exactly does the natural flavour mean? It refers to extracts (提取物) got from natural sources like plants, meat or seafood. When consumers see the “natural flavour” on a label, they are unlikely to assume that someone is squeezing the juice from oranges into their bottles. They know even though natural flavour must come from natural sources, it needn’t all come from the plant or meat. For example, orange flavours might contain not only orange extracts, but also extracts from bark and grass.
So if flavours like orange are needed, why not just use oranges? The answer comes down to “availability, cost, and sustainability”, according to flavour chemist Gary Reineccius of the University of Minnesota. “If you’re going to use all your grapes on grape soda,” Reineccius says, “you don’t have any grapes for wine making; the products are going to be exorbitant; besides, what do you do with the by-products you create after you’ve squeezed all the juice out of the grapes?”
Actually, while chemists make natural flavours by extracting chemicals from natural ingredients, artificial flavours are made by creating the same chemicals artificially. The reason why companies bother to use natural flavours rather than artificial flavours is simple: marketing. “Many of these products have health titles,” says Platkin, professor from Hunter College. “Consumers may be talked to believe products with natural flavours are healthier, though they are nutritionally no different from those with artificial flavours. Natural flavours may involve more forest clear-cutting and carbon emissions from transport than flavours created in the lab.”
Platkin suggests getting more transparent (易懂的) labeling on packaging that describes exactly what the natural or artificial flavours are, so consumers are not misled into buying one product over another because of “natural flavours”. Reineccius also offers simple guidance: “Don’t buy anything because it says ‘natural flavours’. Buy it because you like it.”
1. Which is misunderstanding about the “natural flavour” juice according to Paragraph 1?
A. It comes from 100% original fruit.
B. It is nothing but advertising tricks.
C. It certainly contains extracts made in the lab.
D. It is absolutely safer than juice with artificial flavours.
2. What does the underlined word “exorbitant” in Paragraph 2 probably mean?
A. Popular. B. Expensive. C. Favorable. D. Innovative.
3. Why do companies use natural flavours in the products?
A. To cut the costs. B. To promote the sales.
C. To advocate a healthy diet. D. To avoid food safety issues.
4. What can we conclude from the text?
A. Gary and Platkin hold opposite perspectives.
B. Natural flavours are more environmentally friendly.
C. Customers are misled for ignoring labels on packaging.
D. Natural and artificial flavours are more alike than you think.

Passage 2
(2026·山东聊城·一模)
In the age of large language models (LLMs) and generative AI, we are witnessing an unprecedented transformation in how knowledge is produced, spread and consumed.
LLMs, we are told, make us more efficient, simplify complex work, automate boring tasks and allow us to focus on what matters. But as we feel surprised at their capabilities, a pressing concern emerges: Are these models genuinely boosting efficiency, or are they eroding our capacity for independent thought, judgment and critical reflection?
Efficiency is not a neutral term. The current narrative around generative AI treats efficiency as progress. It suggests that the faster something is done, the better. But faster is not always better. And not everything that can be automated should be.
The popular belief is that LLMs allow humans to assign repetitive work to machines and reserve their energy for more reflective tasks, but the opposite is often true. As the more intellectual labor — writing, summarizing and decision-making, for example — is handed over to AI, the less we will engage with it ourselves. Instead of reserving our thoughtfulness for higher tasks, we will increasingly lose the opportunities, and perhaps even the ability, to think critically.
So what do we really mean by “efficiency”? If it means shortening the time it takes to write a report, perhaps we have succeeded. But if it means replacing the intellectual effort that creates depth, coherence and reflection, then it’s not a gain; it’s a loss. The moment we accept LLMs as thought substitutes, rather than thought aids, we begin to worsen the very conditions under which human reasoning thrives: questioning, dialogue, uncertainty and contradiction.
There is no turning back the presence of LLMs in our lives. But we can choose how to live with them. The question is not whether they will think for us, but whether we will let them define what it means to think at all. Efficiency, in the true sense, should not be about doing more with less thought. It should be about doing better, with deeper attention, stronger ethics and sustained human insight.
1. What does the underlined word “eroding” in paragraph 2 mean?
A. Changing. B. Improving. C. Destroying. D. Expanding.
2. What do LLMs lead to, according to paragraph 4?
A. We get more reflective labor. B. We do independent thinking less.
C. We engage in more repetitive tasks. D. We reduce our work efficiency indeed.
3. What does the author advocate about our using LLMs?
A. Putting efficiency first. B. Reducing intellectual effort.
C. Achieving more with less time. D. Increasing human engagement.
4. What is the author’s purpose in writing the text?
A. To describe the fast development of LLMs.
B. To reflect on the negative effects of LLMs.
C. To question the necessity of pursuing efficiency.
D. To challenge the traditional definition of efficiency.
【答案】1. C 2. B 3. D 4. B

Passage 3
(2026·山东潍坊·一模)
In our fast-paced, stressful lives, we’re often turning to social media, online shopping, or gaming to escape daily pressures. However, the experience can often be the opposite, leaving us more exhausted. This begs the question: do we scroll because we’re stressed, or are we stressed because we scroll?
To better understand the subtle (微妙的) relationship of stress a and internet use, particularly how specific online behaviors influence stress levels. Belal’s team, from Finland’s Aalto University, conducted one of the first studies. They recorded real-world internet usage through tracking software installed on participants’ devices. Combined with a large sample size and a lengthy observation period, the findings offer especially valuable insight into bow online habits tie in with stress.
The study, published in the Journal of Medical Internet Research, collected internet usage data from around 1,500 adults over a seven-month period, comprising nearly 47 million web visits and 14 million app sessions. When compared with participants’ self-reported stress levels from questionnaires, researchers found a strong link between internet use and increased stress, particularly among those who already experienced daily stress. Women consistently reported higher stress levels than men, while stress tended to decrease with age and wealth. Not all online activities were equal, though. The study found that extended time spent on social media, online shopping, and gaming platforms was associated with higher stress levels compared to activities like checking emails or reading the news.
There are always concerns over internet life, especially increasing social media engagement, and some countries, such as Australia, banned social media for anyone under 16. The researchers hope that by gathering more detailed information about people’s internet habits, they can eventually develop concrete recommendations and tools that support healthier, more regulated online engagement. Juhi Kulshrestha, assistant professor at the Department of Computer Science, cautions against oversimplified solutions. She believes that blanket bans on internet use may overlook the emotional support certain online spaces provide. And it’s really crucial to study these issues further so the chicken and egg problem can be solved.
The research team plans to explore how different types of news — political, entertainment, or sports coverage — affect stress, helping further clarify the internet’s complex role in mental health.
1. Why did Belal’s team conduct their research?
A. To compare job-related stress levels.
B. To prove why internet use results in stress.
C. To create apps to help lower stress in adults.
D. To study how stress interacts with internet use.
2. What is a feature of the research method?
A. Focusing on a specific age group.
B. Conducting nationwide online interviews.
C. Collecting large-scale real data over time.
D. Using lab experiments to measure stress levels.
3. Which online activity likely causes the least stress according to the research?
A. Checking emails. B. Shopping.
C. Playing games. D. Chatting.
4. What does Juhi warn against?
A. Judging a book by its cover. B. Sacrificing tomorrow for today.
C. Painting everything with the same brush. D. Counting your chickens before they hatch.
【答案】1. D 2. C 3. A 4. C

Passage 1
(2026·山东淄博·一模)
Time is something we feel every day — rushing to school, glancing at watches, counting down minutes. Yet, surprisingly, modern physics struggles to explain why time moves forward at all. Einstein’s theory of relativity describes time as part of a fixed 4D spacetime, where past, present, and future coexist like pages in a book. Quantum mechanics (量子力学) does not naturally treats time as special — many processes could run backward just as well. So where does time’s flow come from?
A groundbreaking perspective was proposed in 1983 by scientists Page and Wootters. They proposed that time is an illusion (幻觉) created by quantum entanglement (纠缠). They envisioned the universe as a timeless quantum state. When one part acts as a “clock” and becomes entangled with the rest, time seems to emerge — just like page numbers help us read a story in order.
Experimental support is accumulating. In a 2024 study, scientists created a model using entangled quantum magnets and a spring. The entire system was static (静态的), yet the spring’s state changed over time relative to the clock, demonstrating how time might arise from entanglement.
But what could serve as the universe’s real clock? Italian physicist Paola Verrucci points to black holes. They are isolated, highly energetic, and — thanks to Hawking radiation — can entangle with the outside world. “It’s a perfect clock,” she says. “You can’t touch it, but you can be linked to it.”
More strikingly, Verrucci argues time’s direction may come from quantum measurement. Each time we observe reality, possibilities collapse into facts — a one-way process. “You create time,” she says, “when you ask what time it is.” This view transforms our role from passive witnesses of time to active participants. Time may not be a pre-existing river carrying us, but a story we co-write through our interactions with a quantum universe.
1. What can we know from paragraph 1?
A. The theory of relativity views time as independent of space.
B. Modern physics can explain why time moves forward easily.
C. Quantum mechanics specially focuses on the study of time.
D. Our understanding of time varies from physics perspectives.
2. Why did the scientists create the model?
A. To explain the quantum entanglement.
B. To support a timeless quantum state.
C. To show how time comes from entanglement.
D. To confirm time exists in a static universe.
3. Which viewpoint might Verrucci agree with?
A. Hawking radiation generated time. B. There is no ideal clock in universe.
C. Observing time helps to create time. D. Time existed as a river before humans.
4. What is the main purpose of the text?
A. To present the history of quantum mechanics.
B. To explore the origin of time from quantum links.
C. To compare a couple of known spacetime theories.
D. To illustrate technology of quantum entanglement.
【答案】1. D 2. C 3. C 4. B

Passage 2
(2026·山东临沂·一模)
Fifteen decades ago, Francis Galton first came up with the term “nature versus nurture”, and this debate over the factors shaping human identity has long been a central topic in human sciences. Do our genes determine our life paths, as hereditarians (遗传论者) argue? Or are we born as empty paper, shaped merely by the experiences we have in our families and the wider world? Today, however, a new branch of science is ready to overturn the debate. Through this new perspective, nature and nurture are hardly separable at all — genes and the environment do not act independently, but instead interact closely and even shape one another in tangible ways.
Genes do not shape our identities merely on their own within our bodies; instead, they function partly by molding the environments we choose or create. A striking finding of this research is that our environment is, in part, shaped by the genes of the people around us. Initial research suggests that your partner’s genes influence your likelihood of depression almost a third as much as your own genes do. A few students with a genetic trend for smoking in a high school seemed to cause smoking rates to skyrocket across the entire grade — even among students who have no direct contact with these students — like a gene-driven wildfire spreading through social networks.
Genes alone aren’t enough to determine these outcomes and neither is environment. Nature and nurture both shape each other, with nature influencing the way we experience nurture and nurture influencing the way our nature expresses itself. The more opportunities and information the environment provides — the more varied environments become — the bigger the role that genetic variation plays in distinguishing us into different groups.
Nature and nurture aren’t separate forces — they’re a Möbius strip (莫比乌斯环), endlessly circling back on each other. This interdependence means their interaction is fluid and reciprocal, a core insight of sociogenomics that bridges genetic and social science.
1. Why did the author mention the “nature versus nurture” debate in paragraph 1?
A. To emphasize the dominant role of family experiences.
B. To introduce a long-standing core topic in human sciences.
C. To highlight the weakness of early hereditarians’ arguments.
D. To lay a contrastive foundation for a new scientific perspective.
2. What can be inferred from the example of students?
A. Smoking behavior spreads mainly through direct persuasion.
B. Genetic tendencies can indirectly change group behavior.
C. School rules fail to control students’ genetic instincts.
D. Only smokers’ friends adopt the same genetic risks.
3. What happens when environments become more diverse according to paragraph 3?
A. People rely less on their genetic traits. B. Genetic differences play a smaller role.
C. Genetic differences become more influential. D. Nurture becomes more important than nature.
4. What does the author mean by comparing nature and nurture to a “Möbius strip”?
A. They depend entirely on physical conditions.
B. They have a one-way influence on each other.
C. They form a complex, continuous cycle of impact.
D. They are two separate parts of human development.
【答案】1. D 2. B 3. C 4. C

Passage 3
(2026·湖南师大附中·一模)
Plenty of previous research has shown that interacting with nature reduces stress, but it is not clear how long and how often the engagement needs to be. A new study published in the journal Frontiers in Psychology suggests that you don’t have to devote a full day, or even several hours to benefit from the contact with nature.
MaryCarol Hunter, the study’s lead author, and her colleagues recruited 36 residents of Michigan, almost all of whom were women and white. They instructed the participants to spend 10 minutes or more, at least three times a week, in an outdoor space where they could interact with nature.
In the hope of reflecting how people might realistically engage with nature as they go about their everyday lives, the researchers gave the participants permission to choose where and when they visited those outdoor spaces. The participants were also instructed to avoid accessing the Internet, taking phone calls, reading or engaging in conversations while they were there to minimize factors known to influence stress.
Every two weeks the participants collected saliva (唾液) samples before and after their nature experience. The researchers used those samples to measure levels of the stress hormone cortisol (皮质醇), a body chemical known to be related to stress.
The study found that the participants’ levels of cortisol dropped by an average of 21 percent after spending time in an urban green space. The effects were most pronounced when the nature experience was between 20 and 30 minutes long. Levels of the hormone dropped further when participants spent longer periods, but at a slower rate.
This study was quite small, and its participants were not diverse. Furthermore, it measured only drops in biomarkers for stress instead of direct impact on specific health outcomes. Still, the study’s findings are in line with a growing body of research that supports the idea that spending time in or living near a green space can have a positive effect on health and provides the first estimates of how nature experiences impact stress levels in the context of normal daily life.
1. What does Hunter’s study focus on?
A. The role of cortisol in stress reduction. B. The benefits of spending time outdoors.
C. The impact of nature on physical health. D. The ideal duration in nature for stress relief.
2. Why were the participants prohibited from certain activities in outdoor spaces?
A. To keep disturbing factors from affecting stress.
B. To test their ability to stay offline for a long time.
C. To reflect how people realistically engage with nature.
D. To encourage participants to focus on physical exercise.
3. What does the underlined word “pronounced” in paragraph 5 mean?
A. Direct. B. Lasting. C. Slight. D. Significant.
4. What does the author think of Hunter’s study?
A. Unreliable but novel. B. Specific and influential.
C. Limited but informative. D. Comprehensive and valid.
【答案】1. D 2. A 3. D 4. C

Passage 1
(2026·山东滨州·一模)
A reforestation revolution is being led by the innovative use of autonomous drones, a practice that balances deep respect for nature with cutting-edge technology. These drones, which work with high precision, are particularly effective in restoring large areas of forests damaged by wildfires and heavy logging. Reports show they can plant trees up to ten times faster than traditional methods, greatly boosting sustainability.
The core of this technology lies in the combination of AI and LiDAR (Light Detection and Ranging) remote sensing. The drones use LiDAR to scan damaged areas and measure the distance between the sensor and the ground. This system assesses key environmental factors such as soil composition, moisture levels and terrain contour, as well as potential risks like erosion and flooding. Then, onboard AI analyzes all these details carefully to precisely determine the best spots for planting native seeds.
Each drone carries hundreds of biodegradable capsules. These capsules contain not only seeds but also nutrients and fungi, which help the roots thrive in harsh conditions. After identifying ideal areas, the drones fire the capsules into the soil, covering an area as large as a soccer field in less than an hour. The fungi in the capsules enrich the soil, attracting insects and animals that enable forests to thrive. This effect is also crucial for carbon sequestration, which is the process of capturing and storing carbon dioxide to prevent it from warming the planet, and is an important part of the strategy against climate change.
Initial trials in wildfire-hit Kumamoto have achieved remarkable success, with an 80% germination (萌芽) rate, much higher than the 30 — 50% of manual methods. This success has drawn international attention: the US and the UK have adopted similar AI-led drones for reforestation in hard-to-access areas, showing great global promotion potential.
Despite the achievements, challenges remain. Scaling up the project requires huge investment and may face hurdles like airspace restrictions. Additionally, the technology needs to adapt to diverse ecosystems with varying soil and climate. However, these drones bring bright prospects for global sustainability, with potential applications in restoring biodiversity, rehabilitating coral reefs and reversing desertification, playing a positive role in global ecological protection.
1. What are the major advantages of the drone reforestation?
A. High accuracy and great efficiency.
B. Low expense and easy maintenance.
C. Long service lifespan and consistent updates.
D. All-weather adaptability and complete safety.
2. What is the main function of the fungus in the capsules?
A. To protect the seeds from being damaged.
B. To provide food for insects and animals.
C. To enhance root growth and soil health.
D. To help break the capsules into pieces.
3. How does the author present his ideas in paragraph 4?
A. By analyzing reasons and stating results.
B. By listing statistics and giving examples.
C. By giving a definition and making a contrast.
D. By making comparisons and quoting an expert.
4. What can be inferred about the technology according to the last paragraph?
A. It holds great promise despite present barriers.
B. It makes advances in large-scale application.
C. It can easily adapt to diverse ecosystems.
D. It removes restrictions to sustainability.

Passage 2
(2026·广东大湾区·一模)
If the Amazon forest is to disappear, Altamira in Brazil is the town where that end could be foreseen. During the region’s development, a road was cut through the heart of the forest, marking an era of widespread destruction that remade the Amazon. Altamira thus became known in local media as the “champion of deforestation.”
Now Brazilian officials think this expansive town can also be the site of the forest’s rebirth. This year, the government set out to test a question that until now has largely been left to researchers: If left alone, can the Amazon forest restore itself? To test this assumption, officials closed off a degraded parcel of land and leased (租赁) it to a private carbon credit company to safeguard and restore. “Some of the tasks will be done by planting trees. But most of the restoration job will be left to Mother Nature. It’s called passive restoration. This is opening a new model that may be applied across the state,” said Governor Barbalho.
The search for solutions in the Amazon couldn’t be more urgent. Rates of deforestation have been dropping since the government made fighting environmental crime a priority, but the destruction hasn’t stopped. Nearly 6,300 square kilometers were lost last year, bringing the ecosystem closer to what scientists warn is a tipping point, when the Amazon is no longer able to maintain its own rainy ecosystem. Evidence of its arrival is springing up: dried riverbeds, forest fires, punishing droughts, and increased tree death. Scientists have predicted the forest could experience a broad ecological collapse by 2050, when 10 — 47% of it will be exposed to various disturbances that could activate unexpected ecosystem changes.
But other research has also provided cause for hope. Despite the delicate nature of the Amazon’s ecosystem, the forest has also demonstrated a remarkable capacity for recovery. A recent study showed that roughly 72,000 square kilometers of destroyed forest are already in an advanced stage of natural recovery.
1. What do we know about Altamira from paragraph 1?
A. It reshaped the Amazon area. B. It saw the rebirth of the forest.

Passage 3
(2026·山东济宁·一模)
Chaotan One, the world’s first commercial power generator that uses supercritical carbon dioxide (sCO₂), has begun operations in China. This achievement breaks a century-old tradition of using steam for power generation, marking a major improvement in efficiency.
The invention of the steam engine was a first step towards the Industrial Revolution that changed the world. Over the years, the engine’s efficiency was further improved through different designs and fuels; however, the medium for doing work remained the same — steam.
Scientists seeking further improvements in power efficiency noticed that a significant portion of energy is wasted generating steam to drive turbines (涡轮机). Water needs to be boiled first and needs to undergo a phase change to generate steam. Scientists have been looking for a better medium to replace steam.
They found this in sCO₂. CO₂ exists as a gas at room temperature and can be cooled to form dry ice by reducing pressure and lowering temperature. When temperature is raised to 31°C, and pressure is increased to 7.37 MPa, CO₂ enters its supercritical state, where it exhibits properties of both a liquid and a gas. In applications such as moving a turbine, this is extremely useful since the gas-like state offers less resistance while the liquid-like state provides greater push power.
The power generation process works like this: The CO₂ is first pressurized into a supercritical state. Then the sCO₂ passes through a heat exchanger, absorbing heat from an external heat source, and its temperature rises to 400 — 600℃ with a substantial increase in internal energy. After that, it enters a turbine and expands rapidly, driving it to move at a high speed and transforming thermal (热的) energy into mechanical energy, which is then further turned into electrical energy for output. The CO₂ remains in a supercritical state throughout the entire process, with no phase change loss.
The success of the Chaotan One will likely start a new era in power generation, using CO₂ as a medium and bypassing the need to transform water into steam.
