Passage 1
(25-26九年级上·北京西城·期中)Soft robots are a new and exciting type of robot. They are very different from the traditional robots you might see in factories. Those robots are often made from hard metal and plastic, but soft robots are built from special and bendable (可弯曲的) materials. These new materials can bend, stretch, and change shapes, making new robots real “Transformers”. Because they are so soft and flexible, they can move through very narrow spaces and complex (复杂的) paths. This makes them perfect for tasks inside the human body, where they can travel without causing any damage (危害).
However, for a long time, scientists faced a big challenge. It was very difficult to add sensors to these soft robots. Sensors are like the robot’s “eyes” and “ears”; they help the robot understand its environment. Without them, the robot couldn’t be truly useful. Researcher Larry Cheng from Penn State University explained, “The key was making them smart. We needed robots that could sense the world around them and then act independently.”
The solution to this problem was to create special electronic parts that can also bend. Traditional electronics are hard and stiff, and they would stop the soft robot from moving properly. Cheng’s team worked on a new design. They used soft and bendable electronics and spread them across the robot’s body like a net. They also added tiny magnetic (磁性的) materials inside the robot’s soft body. Now, by using magnets from the outside, doctors or rescuers can control the robot wirelessly. The robot can crawl, roll, and twist, all without needing any batteries or wires.
Of course, developing this technology was not easy. The team had to solve two main problems. First, even bendable electronics were still much harder than the robot’s very soft material. Cheng described their creative solution: “We put the electronics together like puzzle pieces. This way, they could fit and connect with each other but still bent when the robot moved.” The second problem was that the magnetic fields used for control could interfere with the electronic signals. As a result, sensors can’t be connected with the signals. To fix this, the team had to carefully redesign the circuit (电路) to protect them from the magnets, making sure that the sensors stay accurate (准确的).
Thanks to these improvements, these smart soft robots can now work with much less human guidance. Imagine an earthquake rescue scene: a small, soft robot could go through the cracks in the damaged buildings to find the injured people who are unable to escape out by sensing their body heat. In medicine, the applications are even more amazing. A medical version could sense chemical changes in the body and carry drugs exactly to the place that needs treatment. Researchers are already developing a robot as small as a pill: “It could go into a patient’s body,” said Korean scientist Suk-Won Hwang, Cheng’s partner. “It could then examine the working system inside the body, collect samples, or even treat diseases without any operation or cut.” Looking even further into the future, the team plans to create tiny new soft robots for blood tubes treatments. “If we can make them small enough to get into blood tubes, they could help repair heart problems or carry medicine directly to cancer cells,” Cheng described.
These future robots don’t have names yet. There is a fun idea that the public might help suggest names for them. When asked about this naming possibility, Cheng laughed and said, “That’s a fun idea!” It seems that the future of soft robots is not only smart but also full of creativity.
1.What is the biggest advantage of soft robots?
A.Simple control. B.Cheap and soft materials.
C.Attractive designs. D.Free movements in narrow spaces.
2.What do the underlined words “interfere with” in Paragraph 4 probably mean?

A.Robots That Can Sense Their World B.Robots for Rescue and Medical Care
C.A New Robot: Bending into the Future D.A Little Doctor: Robots in Future Medicine
Passage 2
(25-26九年级上·北京·期中)Today we can do everything with apps: pay bills, order food and shop for anything. Mobile technology means we can hold the world in our hands. However, when it comes to technology and health care, opportunities (机遇) and risks come together.
Let’s start with the ways to get health care. techno-health (远程医疗) can allow a patient to use technology to see the doctor online and get a diagnosis (诊断) and medical advice without leaving home.
Also, there are many patient websites. These allow for different kinds of communication about our health needs without talking to the medical team. Setting a date with doctors and reading lab results are readily achieved by technology.
A whole new age of medical care seems likely to come in the future. But every coin has two sides. What might be on the other side of techno-health care?
Firstly, we should think about the health care experience as a whole. A usual visit to a doctor begins with a receptionist (接待员) , who can see and tell how a patient is doing, This may influence the quality of care. It’s unlikely that a patient website will have such intuition. For example, a receptionist might notice if a patient looks not well or sounds worried, and can quickly tell a doctor.
Next, sharing the details of one’s life needs trust, which takes time to build. This is certainly true in health care, where we share some of life’s best and worst moments with doctors. The human touch should not be undervalued and is unlikely to be there over the smartphone.
Lastly, test results can be difficult to understand. When someone without a medical degree sees a flagged result with no explanation on the website, there’s room for all kinds of stories to form in their minds— and also great worry.
So how does medicine adapt (适应) to the new technology age? Very smart companies are working on it. There is medical equipment (设备) that can be used at home to send necessary health information and heart sounds through techno-health. It seems likely that some companies will find a way to explain test results.
But what it will not achieve is the warmth of human connection and touch. Patients often need someone to listen to and care about their journey story, which will never be realized through a human-less technology. Technology should be a tool, but depending on it totally will most certainly have unexpected effects. Let’s not allow the loss of humanity (人性) to be one of them.
1.According to the passage, how does technology help health care?
A.It encourages doctors to voice their needs on the websites.
B.It offers the patient a convenient way to get a diagnosis.
C.It improves relations between doctors and patients.
D.It provides an opportunity to build a medical team.
2.The word “intuition” in Paragraph 5 probably means ________.
A.an ability to understand B.an interesting experience
C.a chance to win D.a fair decision
3.What do you know about techno-health care from the passage?
A.Patient websites require trust from doctors. B.Talented companies can give medical advice.
C.Flagged results may cause worry for patients. D.Medical equipment collects patients’ stories.
4.The writer probably agrees that ________.
A.technology can deal with unexpected effects
B.techno-health can take the place of usual health care
C.it is difficult for patients to adapt to the new technology age
D.techno-health care should consider humanity
Passage 3
(25-26九年级上·北京·期中)As restaurants more and more use technology for placing food orders, a new University of South Florida (USF) study has shown that digital ordering platforms greatly affect consumer behavior.
“While digital ordering can make things more convenient and efficient, many consumers will choose unhealthier food and spend more,” said Dipayan Biswas, a professor of marketing at the Muma College of Business. “Our research points out the importance of understanding how digital devices influence our decision-making.”
Through six studies at restaurants and two in a USF School of Marketing and Innovation lab, Biswas and his graduate students studied the effect of ordering from a digital menu vs. a physical menu. The team looked at more than 23,000 orders from different restaurants, including an independently owned Mexican food restaurant and a major global dining chain with 1,000 locations across 23 countries.
The study found 61% of digital orders, including those made for delivery, were unhealthy—more than 3% higher than non-digital orders. The team also found that digital menus have a bigger impact on what consumers order for dinner, since they tend to be more tired and depend more on technology later in the day. Therefore, digital ordering technologies may have less influence on consumers during breakfast and lunch.
“Digital ordering modes lead to a more automatic decision-making process with less mental effort,” Biswas said. “This is because digital tools encourage people to rely less on their thinking ability and more on automatic processes.” This phenomenon is known as the “Google Effect”. The reduced mental effort in digital contexts can result in more automatic decision-making, leading to more indulgent (放纵的) food choices.
According to Biswas, restaurant managers could use this research to adjust their offerings. “Restaurant managers who want to promote healthier options may benefit from offering non-digital ordering modes or some may be interested in promoting indulgent items during dinner hours through digital ordering to increase sales,” Biswas said.
1.What is the purpose of Biswas’s research on digital ordering?
A.To stress the technological advance. B.To encourage healthy eating habits.
C.To reveal its position in the market. D.To examine its impact on food selection.
2.What is paragraph 3 mainly about concerning the study?
A.Its background. B.Its methods. C.Its significance. D.Its findings.
3.What effect might digital ordering have on consumers?
A.More food consumption. B.Reduced mental effort.
C.Healthier food choices. D.Enhanced dining experiences.
4.What does Biswas suggest restaurant managers do to promote healthier eating habits?
A.Complete menus with nutritional information. B.Expand the range of healthy foods.
C.Employ traditional ordering modes. D.Raise the prices of unhealthy items.
Passage 4
(25-26九年级上·北京顺义·期中)
The Rise of EdTech: A New Way to Learn
The way we learn is changing rapidly. In recent years, Educational Technology, or “EdTech” for short, has become a powerful force in classrooms and homes around the world. From interactive apps to online courses, technology promises to make learning more engaging and personalized. But is this shift entirely positive? Many educators and students are beginning to ask important questions about the role of technology in education.
EdTech offers many exciting benefits. For example, language learning apps can offer instant feedback on pronunciation, and online platforms can provide thousands of courses on everything from coding to art history. This allows students to learn at their own pace and explore their unique interests. It can also make quality education more accessible to people in remote areas.
However, some challenges come with these new tools. Critics (批评者) worry that too much screen time can reduce students’ attention spans and make it harder for them to focus on traditional learning. There is also a concern that the constant use of algorithms(算法) to personalize books might create “filter bubbles,” where students only see information that matches their current level and interests, limiting their exposure to new and challenging ideas. Moreover, not every student has equal access to the latest devices and a fast Internet connection, which could widen the gap between the rich and the poor.
The key, many experts argue, is balance. Technology should be a tool to support learning, not replace fundamental skills like critical thinking and deep reading. Just as a calculator(计算器) helps with math but doesn’t teach us how to think logically, EdTech should assist, not control, the learning process. The most successful classrooms of the future will likely be those that mix the best of traditional teaching with the most effective new technologies, ensuring that students develop both digital literacy and essential human skills.
1.What is one main advantage of EdTech mentioned in the passage?
A.It makes teachers less necessary.
B.It completely replaces traditional textbooks.
C.It allows students to learn at their own pace.
D.It ensures all students get the same information.
2.What is the “filter bubble” effect in personalized learning?
A.It protects students from harmful online content.
B.It makes learning apps run faster on old devices.
C.It helps teachers track students’ progress more easily.
D.It limits the information and challenges students come across.
3.What does the underlined word “balance” in the last paragraph most probably mean?
A.Finding a healthy mix of different elements.
B.Sticking strictly to traditional methods.
C.Focusing only on new technology.
D.Letting students choose their preferred way of learning.
4.What is the author’s main purpose in writing this article?
A.To encourage a wise way of using EdTech.
B.To encourage schools to buy the latest EdTech products.
C.To explain why traditional learning methods are outdated.
D.To warn against the dangers of using technology in education.
Passage 5
(25-26九年级上·北京延庆·期中)
Changing who we are inside
It’s long been a scientific dream: to give people a special vaccine (疫苗) before birth to stop them from getting terrible illnesses. Gene editing (基因编辑) is one way in which we could do this. But this method has also created some controversy (争议).
In an online video posted on Nov 26, He Jiankui, a researcher at the Southern University of Science and Technology, said that he had helped to make the world’s first genetically edited babies. The babies are twin girls who were born in November. Their father had HIV (艾滋病病毒). The twins’ genes were edited in order to keep them from being infected by HIV.
He said he chose to do this because HIV is widespread in the world. “I feel such a strong responsibility not only to be the first to do this, but also to set an example.” He told AP.
But his actions raised many questions. Although gene editing may help to prevent disease, many people are wondering if it is safe and ethical (道德的) to use it on humans.
Some believe that gene editing could benefit HIV patients. HIV is “a major and growing public health threat (威胁),” according to Harvard Medical School George Church. Using gene editing for HIV is “justifiable (无可非议的).” Church told AP.
However, others think that gene editing is still in its experimental stages and could result in unexpected mutations (突变). It could cause genetic problems later in life, including the development of cancer, Julian Savulescu from the University of Oxford told BBC News.
Besides, the Ministry of Science and Technology of China has worked with other departments to investigate He Jiankui’s project. In an open letter released on Nov 27,140 Chinese HIV researchers described the research as “unethical”. They questioned the need for He Jiankui’s project.
Others fear that some wealthy people might use gene editing technology to make “designer babies (定制宝宝)”. It would give parents the ability to choose everything from their baby’s eye color to their intelligence. “You could find wealthy parents buying the latest ‘upgrades (升级)’ for their children, leading to even greater inequality (不平等) than we already live with,” Marcy Darnovsky, director of the San Francisco Center for Genetics, told BBC News.
1.What do we know about He Jiankui?
A.He was the first person to edit genes.
B.He was the first person whose genes were edited.
C.He made the world’s first genetically edited babies.
D.He cured twins with HIV when he edited their genes.
2.What does the word “infected” in paragraph 2 probably mean?
A.Cured. B.Attacked. C.Discovered. D.protected.
3.Julian Savulescu said gene editing ________.
A.can cure disease B.will raise ethical questions
C.may lead to greater inequality D.may cause unexpected mutations
4.According to the story, we know that gene editing is ________.
A.justifiable to use B.still controversial
C.good for everyone D.good for wealthy people
Passage 6
(25-26九年级上·北京通州·期中)In addition to applying (申请) for a traditional guide dog, the visually impaired (视障者) will soon have another choice to help with their daily life—a robot guide dog.
The six-legged robot guide dog developed by the School of Mechanical Engineering of Shanghai Jiao Tong University, now being tested, can navigate (导航) users to destinations safely. It also has voice interaction (互动) abilities and can recognize (识别) traffic lights, which traditional guide dogs cannot do.
Now there are millions of visually impaired people in China. They face many problems and need help in their daily life. Guide dogs are important life partners but not everyone is lucky enough to have a traditional companion. “There are only about 400 guide dogs in China. People have to wait for a long time after applying for a guide dog. The cost of training the dogs is very high and the continuous daily cost for users is high, too. This can be another burden (负担) for them,” said Gao Feng, a professor and head of the research development team at the university.
The research in robot guide dogs dates back to June 2021. Gao points out that with six legs, the robot guide dog can walk smoothly with high stability (稳定性) and low noise, which is important and friendly to the users. With cameras, sensors and artificial intelligence technologies, the robot dog can see, listen and speak with users for daily journeys outside and be an assistant at home. Moreover, users can control the walking and running speed of the robot dog. “China’s walking robots are developing rapidly. Now we can produce robot guide dogs at good quality and a low price. We can mass-produce (批量生产) them based on market demand (需求),” said Gao. “The research teams are thoughtful and considerate, and keep making updates. As the robot dog is electronic, it will make it easier to get into public places than with traditional guide dogs.”
Zhang is a visually impaired person. “I will probably try the robot guide dog. Robot dogs can be very precise (精确) and reliable as they seldom make mistakes,” said Zhang. Robot dogs can also guide and accompany people with Alzheimer’s disease, in which the team sees great future demand and potential, according to Gao.
1.What can the robot guide dog do?
A.It can talk with the traditional guide dogs.
B.It can help traditional guide dogs recognize traffic lights.
C.It can listen and speak with its owner.
D.It can recognize its owner with the help of the police.
2.What is Paragraph 4 mainly about?
A.The advantages of the robot guide dogs. B.The history of the robot guide dogs.
C.The function of AI technologies. D.The rules of using the robot guide dogs.
3.What can we learn from the passage?
A.Technology cannot support the mass production of robot dogs.
B.People must spend a long time training the robot dogs.
C.The robot dogs can control the walking speed by themselves.
D.The robot dogs are helpful and will be greatly needed in the future.

Passage 1
(25-26九年级上·北京顺义·期中)Jane Austen (1775-1817), an English novelist, started writing young and completed six novels in her life. Today Austen’s books are more popular than ever. In the last 10 years, five of her six novels have been made into Hollywood films, while her books continue to be best-sellers.
Richard Jenkyns, a professor of English at Oxford University, says that her novels are about marriage, friendships and the family, which are still with us today. “The stories are timeless.” Jenkyns said.
Pride and Prejudice (傲慢与偏见) (1813) is Austen’s most famous work. It is a love story about Elizabeth Bennet and Mr. Darcy. At first, these two dislike each other. Elizabeth is pretty, smart and lively. She is proud because Darcy doesn’t know about her family. Mr. Darcy is handsome, rich and has a better family background. So, he is proud as well. At the same time, Darcy holds a prejudice against the Bennet family. He has no understanding of why the family, especially its mother and daughters should try so hard to find wealthy and powerful husbands. He thinks they are vulgar. Anyway, Elizabeth and Darcy finally fall in love and become a romantic couple but their families don’t want them to.
In Pride and Prejudice, some of the main things that Jane Austen wants to teach people are as follows. Opposites can attract each other. Lovers should not only make each other feel relaxed or comfortable, but also educate and improve each other.
Austen is often called the greatest romantic writer, so it is surprising she remained unmarried. Maybe she was too romantic, waiting for the perfect man, Jenkyns says.
1.From Paragraph 1 and Paragraph 2, we can know________
A.Jane Austen passed away in her fifties
B.Austen’s works remain popular today
C.all of Austen’s works have been made into Hollywood films
D.Austen’s works are mostly about war and the family
2.What does the underlined word “vulgar” in Paragraph 3 mean?
A.庸俗的 B.鲁莽的 C.吝啬的 D.伪善的
3.Which of the following sentences is True?
A.Elizabeth and Darcy fall in love at first sight.
B.Elizabeth has a better family background than Darcy.
C.Darcy has a first good impression of Elizabeth’s family.
D.Elizabeth and Darcy become a romantic couple in the end.

Passage 1
(25-26九年级上·北京·期中)If you’ve ever had to cut short a backyard dinner because of buzzing mosquitoes (蚊子) or worried about yourself getting bitten while playing at the community park, you know how annoying these little insects can be. Worse than that, mosquitoes carry diseases like dengue fever (登革热). This problem has become a bigger problem in parts of China lately, especially as cities grow and the weather changes. For years, we’ve used chemical sprays (喷雾) to kill them, but those often do more harm than good. They pollute the water in the park’s small pond, and what’s worse, they make bees sick, which is a problem because we need bees to help flowers and vegetables grow. That’s why scientists came up with the smart “mosquito vs mosquito” plan. It worked and kept our neighborhoods safe for everyone while building a greener living environment.
The start of this plan is a special “mosquito factory” in Guangzhou’s Huangpu district. When it’s running at its busiest, it can produce 5 million male mosquitoes every week, all of which have a small but important change to their genes. Each of these males has a type of bacteria called Wolbachia (沃尔巴克氏菌), and here’s the good part: they’re totally harmless to us. Unlike female mosquitoes (the ones that bite you for blood), males don’t need blood at all. So how do they help? When these lab-raised males mate with wild females that don’t have Wolbachia, a biological mismatch causes the eggs they lay to fail to develop into baby mosquitoes.
But the plan doesn’t stop there. Scientists also use another helper, which is a type of big, pretty mosquitoes called Toxorhynchites splendens (华丽巨蚊). Not long ago, researchers from Sun Yat-sen University let 75 of these mosquitoes be freed in Foshan’s community parks, the same places where families might walk the dog or kids might chase butterflies. These big mosquitoes are natural enemies of the Aedes albopictus mosquitoes (the ones that spread diseases). Their larvae can control harmful mosquitoes because their babies live in the same small pools of water that harmful mosquitoes love. So people should empty the water from flower pots or old plastic bottles left in the grass. As there’s less water for harmful mosquitoes to lay eggs in, the harmful mosquito larvae (幼虫) get crowded into the few pools that remain. This makes it easy for the giant mosquito larvae to eat 80-100 of them as they grow. Best of all, adult giant mosquitoes only feed on plant sap and flower nectar and they won’t trouble people or pets at all.
Early results are promising. In one small village in Guangzhou, using just the lab-raised males kept dengue fever away for seven years straight. However, getting this to work in big cities isn’t easy. For one thing, the factory costs a lot to run. For another, some people in neighborhoods don’t fully understand the plan. Once, a few residents poured out the water from their flower pots (where the big mosquito babies were living), which killed the big mosquito babies, because they didn’t know those babies were actually helping control the bad mosquitoes. Those baby mosquitoes are a small but important part of protecting the community environment.
Even with these small problems, scientists think this “mosquito vs mosquito” plan is the way to go. They say we should use both methods together to keep mosquito numbers down for a long time without messing up the environment. “We’re not fighting nature here,” a lead researcher said, “We’re working with it to make the places we live, work, and play safer.” The goal is to solve problems not just for now, but in a way that keeps our neighborhoods green and healthy for years to come. This is exactly what we need to do to build a better living space for everyone.
1.What can we learn about the lab-raised male mosquitoes from Paragraph 2?
A.They have passed safety tests and are safe to release in communities.
B.They are the same as wild mosquitoes except for carrying Wolbachia.
C.They are raised in large numbers to bite and kill wild female mosquitoes.
D.They will die after mating with wild female mosquitoes.
2.What can we infer about the “mosquito vs mosquito” plan from Paragraph 4?
A.It is not as effective as using chemical sprays.
B.It needs a lot of money and help from local people.
C.It is only suitable for large cities like Foshan.
D.It will be widely used in China in the near future.
3.What can we learn from the passage?
A.The “mosquito vs mosquito” plan is now being widely used in Foshan.
B.The big, pretty mosquitoes can eat 80 to 100 harmful larvae in their whole life.
C.The “mosquito vs mosquito” plan is a greener way to control mosquitoes than chemical sprays.
D.The lab-raised mosquitoes will finally reduce the number of wild mosquitoes in Foshan.

Passage 1
(25-26九年级上·北京东城·期中)
Why Do Top Athletes Choke Under Pressure?
According to classic economic theory, the higher the reward, the better the expected performance. As a result, we could expect the best performance at the most important moments. But why do we so often see the most talented and experienced athletes perform much worse than expected in important competitions like the Olympics?
Why the Drop in Performance?
It is not necessarily true that there’s a direct relationship between incentives (激励) and achievement. Research has shown that increased motivation (动机) beyond a certain level harms an athlete’s performance. We call this phenomenon “choking under pressure”. Greater incentives may lead to higher levels of arousal (兴奋). The relationship between performance and arousal looks like an inverted U shape (倒U形), meaning that performance is the best at certain levels of arousal and drops with over-arousal.
The desire to perform as well as possible is thought to create performance pressure. Many studies have shown increased pressure has a bad effect on athletes’ performance in skill-based games. When people overthink or consciously monitor each step, the drop in performance happens.
2
Beyond the pressure coming from the important competitions, another thing that may add pressure is the level of expectations. An experiment suggested high audience expectations harm performance in a skill-based task. For example, one of the most famous biathletes in history, Martin Fourcade, said it was very emotional for him to compete in his home country and also much harder than competing abroad because of greater expectations.
We tested this home disadvantage by using data from biathlon (冬季两项) competitions over 17 years. We have found the most titled athletes miss a lot more shots when competing in their home country compared to when they compete abroad. The most reasonable explanation likely relates to the level of expectations from the homeland.
How to Deal with It?
There are several ways to reduce stress, such as a countdown or taking a deep breath before the task. But the base for any solution is to realize that stress affects performance. Choking under pressure can happen to the best athletes and it’s not a shame to admit it. The more athletes know about the effect pressure can have on them, the more likely they are to succeed at the highest level.
1.What can we learn from “choking under pressure”?
A.The higher the reward, the better the expected performance.
B.Better achievement in games results from a drop in pressure.
C.Arousal beyond a certain level harms an athlete’s performance.
D.Athletes’ performance in games has something to do with their training.
2.Which of the following would be the best heading for Paragraph 4 and 5?
A.Pressure as a Key to Improving Performance.
B.Pressure as a Push for Becoming Top-level Athletes.
C.High Expectations as a Cause of Choking Under Pressure.
D.High Expectations as an Incentive to Compete in the Home Country.
3.To deal with pressure, the athletes should first ________.
A.avoid the possible feelings of pressure
B.share their worries with friends and coaches
C.try their best to succeed at the highest level
D.recognize the effect of stress on performance
Passage 2
(25-26九年级上·北京西城·期中)For a long time, people thought that when children became teenagers, parents should step back. But new studies show something different. The teenage years are not a time for parents to be less involved. Instead, they are a time to stay connected, just in new ways.
From Boss to Guide
Parents often act like “managers”. They tell their teens what to do and make all the decisions. However, research now suggests a better role: be a “guide”. A guide does not give orders. A guide offers advice when the teen asks for it. A guide respects that the teenager is becoming more independent but is still there to help. This way, parents use their influence through a strong relationship, not through strict control.
The Growing Teen Brain
Why do teenagers sometimes act unreasonably or have strong mood swings (起伏)? Brain science gives us an answer. The part of the brain that controls good judgment and decision-making is still developing in the teen years. This means that a teen’s sometimes risky or emotional behavior is not just them being difficult—it is a normal part of brain development. Knowing this can help parents be more patient. They can focus on helping their teens learn to make good choices while the brain is still learning how.
What Teenagers Need to Do
Experts say that all teenagers are working on four important tasks as they grow up:
• Be Their Own Person: They want to make their own choices.
• Discover Who They Are: They try out different ideas to find their identity (身份).
• Become More Independent: They naturally create some distance from their parents.
• Make Close Friends: They build strong friendships outside the family.
When parents understand these tasks, they can see their teen’s behavior differently. Arguing about a small rule might really be about the teen’s need for more independence. This new view can reduce fights and help parents support their child’s growth.
One of the most powerful findings is about empathy—the ability to understand and share the feelings of another. Studies show that when teenagers feel understood and listened to by their parents, they are more likely to be understanding and kind to others. Simply listening to a teen’s feelings without immediately judging or solving the problem can build great trust. This kind of connection makes the teenage years easier and helps build a strong, positive relationship for the future.
In summary, these new ideas give parents a more hopeful way to see the teenage years. By being a guide instead of a boss, understanding the teen brain, supporting their growth tasks, and listening with empathy, parents can turn these years into a time of positive growth and a closer bond (联结).
1.According to the passage, which of the following actions best shows the parent’s role as a “guide”?
A.Making a strict daily schedule for the teen to follow.
B.Giving clear instructions on how to solve a problem step by step.
C.Offering advice when the teen needs help with a friendship problem.
D.Telling the teen that his new interest won’t last long and will pass.
2.According to brain science, why do teenagers sometimes have strong mood swings?
A.Because they want to make their parents angry.
B.Because they lack communication with their parents.
C.Because they spend too much time with emotional friends.
D.Because their brain’s area for good judgement is still developing.
3.What is the best heading for Paragraph 6?
A.The Importance of Understanding B.The Power of Listening
C.The Benefit of Connecting D.The Ways of Sharing
4.Which of the following may the writer most likely agree with?
A.Parents should strictly manage their teenagers’ lives to keep them safe.
B.A teenager’s need to make their own choices is a natural part of growth.
C.The main goal of the teenage years is to get good grades for the future.
D.It is hard to build a close bond with teenagers because of their brain.

(25-26九年级上·北京东城·期中)Recently, some people have complained about the purposefully addictive (上瘾的) designs of smartphones and social media, which make it hard for anyone to put them down, especially teens. Now, a new report in Emotion gives facts that back up what these people said.
According to the report, young people’s life satisfaction and happiness have dropped since 2012, the year the percentage of teens owning smartphones started increasing rapidly. The report also finds that teens’ psychological (心理的) health gets worse the more hours a week they spend on screens.
Jean Twenge is the lead writer of the report. She graphed (制图) the connection between happiness and screen activities, such as social media, texting, gaming, and video chats. She also graphed the connection between happiness and non-screen activities, including sports, reading, and face-to-face communications. She called the relationship between screen and non-screen activities “zero sum”—if you are doing one, it takes time away from the others.
Diane Tanman complains that her sons are like that. They are 11 and 15. They used to play games in fields, and it made them happier. These days, her sons are more into online games. Many of the games have rewards (奖励) built in to keep players coming back. “It’s just junk food for the brain,” Tanman said.
Ed Lazzara says his 12-year-old son Leo is a fan of video games. After playing a lot, Leo gets more upset and uncomfortable. He wants his son to play fewer video games.
However, totally staying away from electronic devices (设备) doesn’t lead to happiness, either. Twenge and her co-writers found that the happiest teens used electronic devices a little less than an hour daily. After a daily hour of screen time, unhappiness rises in relation to increasing screen time.
Spending time in front of a screen is a normal part of being a teenager. Many schools require students to be online and to use iPads or other devices to do their work. But teachers and parents have also complained that technology can get in the way of learning when teens use their devices for things other than their studies.
If we recognize how screen time influences young minds, we can help teens use technology better and protect their psychological health in the process. Screen time is like ice cream. Sure, we can have some once in a while, but it shouldn’t be part of our everyday lives.
1.What can we learn from the passage?
A.Screen time at home is not as beneficial as screen time at school.
B.Nearly an hour of screen time every day makes teens happiest.
C.Technology should be encouraged in classroom learning.
D.What teens do on the screen influences their happiness.
2.Why does the passage give the examples of families with teens?
A.To prove the bad effect of the addictive designs of electronic devices.
B.To show parents have little control over their teens’ screen time.
C.To compare different-aged teens’ feelings about screen use.
D.To explain why electronic devices make teens feel happy.
3.Which of the following would be the best title for the passage?
A.Use of Electronic Devices: Should We Consider Teens’ Needs?
B.Teens’ Psychological Health: Why Is It Important?
C.Screen Time and Teens’ Study Performance
D.Screen Time and Teens’ Life Satisfaction
讲述了三项前沿科技成果:模仿蝠鲼研制的软体潜水器、预测蚊子飞行轨迹的3D模型、可把普通手表变为智能手表的传感器,并分别介绍了它们的功能与用途。
【新素材·三项前沿科技成果】
Manta rays inspire new designManta rays (蝠鲼) have big, flat bodies that help them move well in the water. Chinese scientists have made a soft-body submersible in the same shape as the manta ray. This is the world's first soft-body submersible that looks like a manta ray. With two “eyes”, the submersible can “see” in the dark underwater. One looks ahead to find things, while the other looks to the sides to make a map of the ocean floor. The submersible can work in groups.

US scientists have made a 3D model to predict how mosquitoes fly. If mosquitoes can only see a target, they fly quickly toward it. If they can't see a target but can smell something like carbon dioxide (二氧化碳), they slow down and move back and forth to stay close. When mosquitoes can both see and smell the target, they fly in a circle around it and get ready to land. These findings could help make better traps (陷阱) to catch mosquitoes.
“Clever” sensor for your watchWith only a sensor (传感器) as small as a coin, your watch can turn into a smartwatch! This sensor is called The Heir and comes from the US. You can use a micro suction disc (微型吸盘) to stick it to the back of most watches. It counts your steps and sends them to an app on your phone. It also vibrates (振动) to tell you when you get calls and messages. You can also play music on your phone by tapping it.
1.In which SECTION of the newspaper can we most likely read the news?
A.LIFE B.ART C.SCIENCE D.SPORTS
2.What do we know about the soft-body submersible?
①shape ②color ③ working way ④ price
A.①② B.①③ C.③④ D.①④
3.What would be a good heading for the second piece of news?
A.Flight Tracks for Mosquito Traps B.New Ways to Catch Mosquitoes
C.Better Traps from Scientists D.Keep Mosquitoes Away
4.What can we infer about the sensor called The Heir?
A.It is very tiny in size. B.It is mainly used to make calls.
C.It needs to be recharged every day. D.It can be used underwater.

话题1 科学技术(共6篇)
Passage 1
(25-26九年级上·北京西城·期中)Soft robots are a new and exciting type of robot. They are very different from the traditional robots you might see in factories. Those robots are often made from hard metal and plastic, but soft robots are built from special and bendable (可弯曲的) materials. These new materials can bend, stretch, and change shapes, making new robots real “Transformers”. Because they are so soft and flexible, they can move through very narrow spaces and complex (复杂的) paths. This makes them perfect for tasks inside the human body, where they can travel without causing any damage (危害).
However, for a long time, scientists faced a big challenge. It was very difficult to add sensors to these soft robots. Sensors are like the robot’s “eyes” and “ears”; they help the robot understand its environment. Without them, the robot couldn’t be truly useful. Researcher Larry Cheng from Penn State University explained, “The key was making them smart. We needed robots that could sense the world around them and then act independently.”
The solution to this problem was to create special electronic parts that can also bend. Traditional electronics are hard and stiff, and they would stop the soft robot from moving properly. Cheng’s team worked on a new design. They used soft and bendable electronics and spread them across the robot’s body like a net. They also added tiny magnetic (磁性的) materials inside the robot’s soft body. Now, by using magnets from the outside, doctors or rescuers can control the robot wirelessly. The robot can crawl, roll, and twist, all without needing any batteries or wires.
Of course, developing this technology was not easy. The team had to solve two main problems. First, even bendable electronics were still much harder than the robot’s very soft material. Cheng described their creative solution: “We put the electronics together like puzzle pieces. This way, they could fit and connect with each other but still bent when the robot moved.” The second problem was that the magnetic fields used for control could interfere with the electronic signals. As a result, sensors can’t be connected with the signals. To fix this, the team had to carefully redesign the circuit (电路) to protect them from the magnets, making sure that the sensors stay accurate (准确的).
Thanks to these improvements, these smart soft robots can now work with much less human guidance. Imagine an earthquake rescue scene: a small, soft robot could go through the cracks in the damaged buildings to find the injured people who are unable to escape out by sensing their body heat. In medicine, the applications are even more amazing. A medical version could sense chemical changes in the body and carry drugs exactly to the place that needs treatment. Researchers are already developing a robot as small as a pill: “It could go into a patient’s body,” said Korean scientist Suk-Won Hwang, Cheng’s partner. “It could then examine the working system inside the body, collect samples, or even treat diseases without any operation or cut.” Looking even further into the future, the team plans to create tiny new soft robots for blood tubes treatments. “If we can make them small enough to get into blood tubes, they could help repair heart problems or carry medicine directly to cancer cells,” Cheng described.
These future robots don’t have names yet. There is a fun idea that the public might help suggest names for them. When asked about this naming possibility, Cheng laughed and said, “That’s a fun idea!” It seems that the future of soft robots is not only smart but also full of creativity.
1.What is the biggest advantage of soft robots?
A.Simple control. B.Cheap and soft materials.
C.Attractive designs. D.Free movements in narrow spaces.
2.What do the underlined words “interfere with” in Paragraph 4 probably mean?

3.What can we learn about future medical treatments in paragraph 5?
A.Robots will replace doctors. B.Treatment costs will fall a lot.
C.Patients may not need drugs any more. D.Certain operations may become unnecessary.
4.Which of the following would be the best title for the passage?
A.Robots That Can Sense Their World B.Robots for Rescue and Medical Care
C.A New Robot: Bending into the Future D.A Little Doctor: Robots in Future Medicine

Passage 2
(25-26九年级上·北京·期中)Today we can do everything with apps: pay bills, order food and shop for anything. Mobile technology means we can hold the world in our hands. However, when it comes to technology and health care, opportunities (机遇) and risks come together.
Let’s start with the ways to get health care. techno-health (远程医疗) can allow a patient to use technology to see the doctor online and get a diagnosis (诊断) and medical advice without leaving home.
Also, there are many patient websites. These allow for different kinds of communication about our health needs without talking to the medical team. Setting a date with doctors and reading lab results are readily achieved by technology.
A whole new age of medical care seems likely to come in the future. But every coin has two sides. What might be on the other side of techno-health care?
Firstly, we should think about the health care experience as a whole. A usual visit to a doctor begins with a receptionist (接待员) , who can see and tell how a patient is doing, This may influence the quality of care. It’s unlikely that a patient website will have such intuition. For example, a receptionist might notice if a patient looks not well or sounds worried, and can quickly tell a doctor.
Next, sharing the details of one’s life needs trust, which takes time to build. This is certainly true in health care, where we share some of life’s best and worst moments with doctors. The human touch should not be undervalued and is unlikely to be there over the smartphone.
Lastly, test results can be difficult to understand. When someone without a medical degree sees a flagged result with no explanation on the website, there’s room for all kinds of stories to form in their minds— and also great worry.
So how does medicine adapt (适应) to the new technology age? Very smart companies are working on it. There is medical equipment (设备) that can be used at home to send necessary health information and heart sounds through techno-health. It seems likely that some companies will find a way to explain test results.
But what it will not achieve is the warmth of human connection and touch. Patients often need someone to listen to and care about their journey story, which will never be realized through a human-less technology. Technology should be a tool, but depending on it totally will most certainly have unexpected effects. Let’s not allow the loss of humanity (人性) to be one of them.
1.According to the passage, how does technology help health care?
A.It encourages doctors to voice their needs on the websites.
B.It offers the patient a convenient way to get a diagnosis.
C.It improves relations between doctors and patients.
D.It provides an opportunity to build a medical team.
2.The word “intuition” in Paragraph 5 probably means ________.
A.an ability to understand B.an interesting experience
C.a chance to win D.a fair decision
3.What do you know about techno-health care from the passage?
A.Patient websites require trust from doctors. B.Talented companies can give medical advice.
C.Flagged results may cause worry for patients. D.Medical equipment collects patients’ stories.
4.The writer probably agrees that ________.
A.technology can deal with unexpected effects
B.techno-health can take the place of usual health care
C.it is difficult for patients to adapt to the new technology age
D.techno-health care should consider humanity
【答案】1.B 2.A 3.C 4.D
【导语】本文是一篇议论文,探讨了远程医疗(techno-health care)带来的便利与存在的问题,既介绍了科技为医疗健康提供的便捷服务,也指出了远程医疗缺少人性关怀等局限。
【详解】1.文中第二段提到“techno-health (远程医疗) can allow a patient to use technology to see the doctor online and get a diagnosis (诊断) and medical advice without leaving home”,说明科技为患者提供了便捷的诊断方式,对应选项B;A、C、D均与原文表述不符。
2.根据后文例子“a receptionist might notice if a patient looks not well or sounds worried, and can quickly tell a doctor”,能看出接待员有感知患者状态的能力,因此“intuition”在这里的意思是理解、感知的能力,对应选项A。
3.文中第七段提到“When someone without a medical degree sees a flagged result with no explanation on the website, there’s room for all kinds of stories to form in their minds—and also great worry”,说明标记的检查结果可能会让患者产生担忧,对应选项C;A、B、D均不符合原文内容。
4.文章最后一段提到“Technology should be a tool, but depending on it totally will most certainly have unexpected effects. Let’s not allow the loss of humanity (人性) to be one of them”,能看出作者认为远程医疗需要考虑人性关怀,对应选项D。
Passage 3
(25-26九年级上·北京·期中)As restaurants more and more use technology for placing food orders, a new University of South Florida (USF) study has shown that digital ordering platforms greatly affect consumer behavior.
“While digital ordering can make things more convenient and efficient, many consumers will choose unhealthier food and spend more,” said Dipayan Biswas, a professor of marketing at the Muma College of Business. “Our research points out the importance of understanding how digital devices influence our decision-making.”
Through six studies at restaurants and two in a USF School of Marketing and Innovation lab, Biswas and his graduate students studied the effect of ordering from a digital menu vs. a physical menu. The team looked at more than 23,000 orders from different restaurants, including an independently owned Mexican food restaurant and a major global dining chain with 1,000 locations across 23 countries.
The study found 61% of digital orders, including those made for delivery, were unhealthy—more than 3% higher than non-digital orders. The team also found that digital menus have a bigger impact on what consumers order for dinner, since they tend to be more tired and depend more on technology later in the day. Therefore, digital ordering technologies may have less influence on consumers during breakfast and lunch.
“Digital ordering modes lead to a more automatic decision-making process with less mental effort,” Biswas said. “This is because digital tools encourage people to rely less on their thinking ability and more on automatic processes.” This phenomenon is known as the “Google Effect”. The reduced mental effort in digital contexts can result in more automatic decision-making, leading to more indulgent (放纵的) food choices.
According to Biswas, restaurant managers could use this research to adjust their offerings. “Restaurant managers who want to promote healthier options may benefit from offering non-digital ordering modes or some may be interested in promoting indulgent items during dinner hours through digital ordering to increase sales,” Biswas said.
1.What is the purpose of Biswas’s research on digital ordering?
A.To stress the technological advance. B.To encourage healthy eating habits.
C.To reveal its position in the market. D.To examine its impact on food selection.
2.What is paragraph 3 mainly about concerning the study?
A.Its background. B.Its methods. C.Its significance. D.Its findings.
3.What effect might digital ordering have on consumers?
A.More food consumption. B.Reduced mental effort.
C.Healthier food choices. D.Enhanced dining experiences.
4.What does Biswas suggest restaurant managers do to promote healthier eating habits?
A.Complete menus with nutritional information. B.Expand the range of healthy foods.
C.Employ traditional ordering modes. D.Raise the prices of unhealthy items.
【答案】1.D 2.B 3.B 4.C
【导语】本文主要介绍了在数字点餐模式中数字设备如何影响消费者的决策,并对比了传统点餐模式和数字点餐模式。
【详解】1.第一段“a new University of South Florida (USF) study has shown that digital ordering platforms greatly affect consumer behavior.”以及第二段“Our research points out the importance of understanding how digital devices influence our decision-making.”说明该研究的目的是探究数字设备如何影响决策,即考察其对食物选择的影响。
2.第三段首句提到“Through six studies at restaurants and two in a USF School of Marketing and Innovation lab…”,接着介绍了团队分析了23000多份订单。这段主要描述了研究是如何开展的,即研究的方法。
3.根据第五段“Digital ordering modes lead to a more automatic decision-making process with less mental effort”可知,数字点餐模式会导致决策过程更自动化,减少脑力消耗。
4.根据最后一段“Restaurant managers who want to promote healthier options may benefit from offering non-digital ordering modes”可知,Biswas建议想要推广更健康选择的经理提供非数字点餐模式,即传统点餐模式。
Passage 4
(25-26九年级上·北京顺义·期中)
The Rise of EdTech: A New Way to Learn
The way we learn is changing rapidly. In recent years, Educational Technology, or “EdTech” for short, has become a powerful force in classrooms and homes around the world. From interactive apps to online courses, technology promises to make learning more engaging and personalized. But is this shift entirely positive? Many educators and students are beginning to ask important questions about the role of technology in education.
EdTech offers many exciting benefits. For example, language learning apps can offer instant feedback on pronunciation, and online platforms can provide thousands of courses on everything from coding to art history. This allows students to learn at their own pace and explore their unique interests. It can also make quality education more accessible to people in remote areas.
However, some challenges come with these new tools. Critics (批评者) worry that too much screen time can reduce students’ attention spans and make it harder for them to focus on traditional learning. There is also a concern that the constant use of algorithms(算法) to personalize books might create “filter bubbles,” where students only see information that matches their current level and interests, limiting their exposure to new and challenging ideas. Moreover, not every student has equal access to the latest devices and a fast Internet connection, which could widen the gap between the rich and the poor.
The key, many experts argue, is balance. Technology should be a tool to support learning, not replace fundamental skills like critical thinking and deep reading. Just as a calculator(计算器) helps with math but doesn’t teach us how to think logically, EdTech should assist, not control, the learning process. The most successful classrooms of the future will likely be those that mix the best of traditional teaching with the most effective new technologies, ensuring that students develop both digital literacy and essential human skills.
1.What is one main advantage of EdTech mentioned in the passage?
A.It makes teachers less necessary.
B.It completely replaces traditional textbooks.
C.It allows students to learn at their own pace.
D.It ensures all students get the same information.
2.What is the “filter bubble” effect in personalized learning?
A.It protects students from harmful online content.
B.It makes learning apps run faster on old devices.
C.It helps teachers track students’ progress more easily.
D.It limits the information and challenges students come across.
3.What does the underlined word “balance” in the last paragraph most probably mean?
A.Finding a healthy mix of different elements.
B.Sticking strictly to traditional methods.
C.Focusing only on new technology.
D.Letting students choose their preferred way of learning.
4.What is the author’s main purpose in writing this article?
A.To encourage a wise way of using EdTech.
B.To encourage schools to buy the latest EdTech products.
C.To explain why traditional learning methods are outdated.
D.To warn against the dangers of using technology in education.
【答案】1.C 2.D 3.A 4.A
【导语】本文是一篇议论文,主要探讨了教育科技(EdTech)在教学中的兴起,分析了它带来的好处和面临的挑战,并指出未来教育的关键在于平衡技术与传统教学,让技术作为辅助工具来支持学习。
【详解】1.细节理解题。根据文章“This allows students to learn at their own pace and explore their unique interests.”可知,教育科技的一个主要优势是允许学生按照自己的节奏学习。故选C。
2.细节理解题。根据文章“there is also a concern that the constant use of algorithms to personalize books might create “filter bubbles”, where students only see information that matches their current level and interests, limiting their exposure to new and challenging ideas.”可知,“filter bubbles”效应会限制学生接触新的、有挑战性的信息。故选D。
3.词句猜测题。根据文章“Technology should be a tool to support learning, not replace fundamental skills” 可以看出,作者认为技术是“辅助工具”,而非“替代者”,最后一句 “mix the best of traditional teaching with the most effective new technologies”直接点明了balance的内涵:将传统教学的优势与最有效的新技术相结合,找到两者之间的健康平衡点。因此,balance在这里指在不同元素(传统教学与新技术)之间找到健康的混合与平衡。故选A。
4.主旨大意题。文章既分析了教育科技的优势,也指出了挑战,最后提出关键在于“平衡”,即让技术作为辅助工具,与传统教学结合。这表明作者的主要目的是鼓励以明智的方式使用教育科技。故选A。
Passage 5
(25-26九年级上·北京延庆·期中)
Changing who we are inside
It’s long been a scientific dream: to give people a special vaccine (疫苗) before birth to stop them from getting terrible illnesses. Gene editing (基因编辑) is one way in which we could do this. But this method has also created some controversy (争议).
In an online video posted on Nov 26, He Jiankui, a researcher at the Southern University of Science and Technology, said that he had helped to make the world’s first genetically edited babies. The babies are twin girls who were born in November. Their father had HIV (艾滋病病毒). The twins’ genes were edited in order to keep them from being infected by HIV.
He said he chose to do this because HIV is widespread in the world. “I feel such a strong responsibility not only to be the first to do this, but also to set an example.” He told AP.
But his actions raised many questions. Although gene editing may help to prevent disease, many people are wondering if it is safe and ethical (道德的) to use it on humans.
Some believe that gene editing could benefit HIV patients. HIV is “a major and growing public health threat (威胁),” according to Harvard Medical School George Church. Using gene editing for HIV is “justifiable (无可非议的).” Church told AP.
However, others think that gene editing is still in its experimental stages and could result in unexpected mutations (突变). It could cause genetic problems later in life, including the development of cancer, Julian Savulescu from the University of Oxford told BBC News.
Besides, the Ministry of Science and Technology of China has worked with other departments to investigate He Jiankui’s project. In an open letter released on Nov 27,140 Chinese HIV researchers described the research as “unethical”. They questioned the need for He Jiankui’s project.
Others fear that some wealthy people might use gene editing technology to make “designer babies (定制宝宝)”. It would give parents the ability to choose everything from their baby’s eye color to their intelligence. “You could find wealthy parents buying the latest ‘upgrades (升级)’ for their children, leading to even greater inequality (不平等) than we already live with,” Marcy Darnovsky, director of the San Francisco Center for Genetics, told BBC News.
1.What do we know about He Jiankui?
A.He was the first person to edit genes.
B.He was the first person whose genes were edited.
C.He made the world’s first genetically edited babies.
D.He cured twins with HIV when he edited their genes.
2.What does the word “infected” in paragraph 2 probably mean?
A.Cured. B.Attacked. C.Discovered. D.protected.
3.Julian Savulescu said gene editing ________.
A.can cure disease B.will raise ethical questions
C.may lead to greater inequality D.may cause unexpected mutations
4.According to the story, we know that gene editing is ________.
A.justifiable to use B.still controversial
C.good for everyone D.good for wealthy people
【答案】1.C 2.B 3.D 4.B
【导语】本文是一篇说明文。文章介绍了基因编辑技术这一可在人出生前通过特殊疫苗预防严重疾病的科学手段,围绕南方科技大学研究员贺建奎培育出世界首例基因编辑婴儿一事展开,阐述了该技术的应用背景,同时呈现了各方对基因编辑技术的不同看法。
【详解】1.细节理解题。根据“He Jiankui, a researcher at the Southern University of Science and Technology, said that he had helped to make the world’s first genetically edited babies.”可知,贺建奎培育出了世界首例基因编辑婴儿,故选C。
2.词句猜测题。根据“Their father had HIV. The twins’ genes were edited in order to keep them from being infected by HIV.”可知,双胞胎的父亲携带艾滋病病毒,编辑她们的基因是为了防止她们被感染,“infected”意为“感染”,与“Attacked”意思相近,故选B。
3.细节理解题。根据“However, others think that gene editing is still in its experimental stages and could result in unexpected mutations. It could cause genetic problems later in life, including the development of cancer, Julian Savulescu from the University of Oxford told BBC News.”可知,朱利安·萨夫勒斯库认为基因编辑可能会导致意想不到的突变,故选D。
4.细节理解题。根据“But this method has also created some controversy.”以及后文各方对基因编辑技术的支持与反对观点可知,基因编辑技术仍存在争议,故选B。
Passage 6
(25-26九年级上·北京通州·期中)In addition to applying (申请) for a traditional guide dog, the visually impaired (视障者) will soon have another choice to help with their daily life—a robot guide dog.
The six-legged robot guide dog developed by the School of Mechanical Engineering of Shanghai Jiao Tong University, now being tested, can navigate (导航) users to destinations safely. It also has voice interaction (互动) abilities and can recognize (识别) traffic lights, which traditional guide dogs cannot do.
Now there are millions of visually impaired people in China. They face many problems and need help in their daily life. Guide dogs are important life partners but not everyone is lucky enough to have a traditional companion. “There are only about 400 guide dogs in China. People have to wait for a long time after applying for a guide dog. The cost of training the dogs is very high and the continuous daily cost for users is high, too. This can be another burden (负担) for them,” said Gao Feng, a professor and head of the research development team at the university.
The research in robot guide dogs dates back to June 2021. Gao points out that with six legs, the robot guide dog can walk smoothly with high stability (稳定性) and low noise, which is important and friendly to the users. With cameras, sensors and artificial intelligence technologies, the robot dog can see, listen and speak with users for daily journeys outside and be an assistant at home. Moreover, users can control the walking and running speed of the robot dog. “China’s walking robots are developing rapidly. Now we can produce robot guide dogs at good quality and a low price. We can mass-produce (批量生产) them based on market demand (需求),” said Gao. “The research teams are thoughtful and considerate, and keep making updates. As the robot dog is electronic, it will make it easier to get into public places than with traditional guide dogs.”
Zhang is a visually impaired person. “I will probably try the robot guide dog. Robot dogs can be very precise (精确) and reliable as they seldom make mistakes,” said Zhang. Robot dogs can also guide and accompany people with Alzheimer’s disease, in which the team sees great future demand and potential, according to Gao.
1.What can the robot guide dog do?
A.It can talk with the traditional guide dogs.
B.It can help traditional guide dogs recognize traffic lights.
C.It can listen and speak with its owner.
D.It can recognize its owner with the help of the police.
2.What is Paragraph 4 mainly about?
A.The advantages of the robot guide dogs. B.The history of the robot guide dogs.
C.The function of AI technologies. D.The rules of using the robot guide dogs.
3.What can we learn from the passage?
A.Technology cannot support the mass production of robot dogs.
B.People must spend a long time training the robot dogs.
C.The robot dogs can control the walking speed by themselves.
D.The robot dogs are helpful and will be greatly needed in the future.

Passage 1
(25-26九年级上·北京顺义·期中)Jane Austen (1775-1817), an English novelist, started writing young and completed six novels in her life. Today Austen’s books are more popular than ever. In the last 10 years, five of her six novels have been made into Hollywood films, while her books continue to be best-sellers.
Richard Jenkyns, a professor of English at Oxford University, says that her novels are about marriage, friendships and the family, which are still with us today. “The stories are timeless.” Jenkyns said.
Pride and Prejudice (傲慢与偏见) (1813) is Austen’s most famous work. It is a love story about Elizabeth Bennet and Mr. Darcy. At first, these two dislike each other. Elizabeth is pretty, smart and lively. She is proud because Darcy doesn’t know about her family. Mr. Darcy is handsome, rich and has a better family background. So, he is proud as well. At the same time, Darcy holds a prejudice against the Bennet family. He has no understanding of why the family, especially its mother and daughters should try so hard to find wealthy and powerful husbands. He thinks they are vulgar. Anyway, Elizabeth and Darcy finally fall in love and become a romantic couple but their families don’t want them to.
In Pride and Prejudice, some of the main things that Jane Austen wants to teach people are as follows. Opposites can attract each other. Lovers should not only make each other feel relaxed or comfortable, but also educate and improve each other.
Austen is often called the greatest romantic writer, so it is surprising she remained unmarried. Maybe she was too romantic, waiting for the perfect man, Jenkyns says.
1.From Paragraph 1 and Paragraph 2, we can know________
A.Jane Austen passed away in her fifties
B.Austen’s works remain popular today
C.all of Austen’s works have been made into Hollywood films
D.Austen’s works are mostly about war and the family
2.What does the underlined word “vulgar” in Paragraph 3 mean?
A.庸俗的 B.鲁莽的 C.吝啬的 D.伪善的
3.Which of the following sentences is True?

Passage 1
(25-26九年级上·北京·期中)If you’ve ever had to cut short a backyard dinner because of buzzing mosquitoes (蚊子) or worried about yourself getting bitten while playing at the community park, you know how annoying these little insects can be. Worse than that, mosquitoes carry diseases like dengue fever (登革热). This problem has become a bigger problem in parts of China lately, especially as cities grow and the weather changes. For years, we’ve used chemical sprays (喷雾) to kill them, but those often do more harm than good. They pollute the water in the park’s small pond, and what’s worse, they make bees sick, which is a problem because we need bees to help flowers and vegetables grow. That’s why scientists came up with the smart “mosquito vs mosquito” plan. It worked and kept our neighborhoods safe for everyone while building a greener living environment.
The start of this plan is a special “mosquito factory” in Guangzhou’s Huangpu district. When it’s running at its busiest, it can produce 5 million male mosquitoes every week, all of which have a small but important change to their genes. Each of these males has a type of bacteria called Wolbachia (沃尔巴克氏菌), and here’s the good part: they’re totally harmless to us. Unlike female mosquitoes (the ones that bite you for blood), males don’t need blood at all. So how do they help? When these lab-raised males mate with wild females that don’t have Wolbachia, a biological mismatch causes the eggs they lay to fail to develop into baby mosquitoes.
But the plan doesn’t stop there. Scientists also use another helper, which is a type of big, pretty mosquitoes called Toxorhynchites splendens (华丽巨蚊). Not long ago, researchers from Sun Yat-sen University let 75 of these mosquitoes be freed in Foshan’s community parks, the same places where families might walk the dog or kids might chase butterflies. These big mosquitoes are natural enemies of the Aedes albopictus mosquitoes (the ones that spread diseases). Their larvae can control harmful mosquitoes because their babies live in the same small pools of water that harmful mosquitoes love. So people should empty the water from flower pots or old plastic bottles left in the grass. As there’s less water for harmful mosquitoes to lay eggs in, the harmful mosquito larvae (幼虫) get crowded into the few pools that remain. This makes it easy for the giant mosquito larvae to eat 80-100 of them as they grow. Best of all, adult giant mosquitoes only feed on plant sap and flower nectar and they won’t trouble people or pets at all.
Early results are promising. In one small village in Guangzhou, using just the lab-raised males kept dengue fever away for seven years straight. However, getting this to work in big cities isn’t easy. For one thing, the factory costs a lot to run. For another, some people in neighborhoods don’t fully understand the plan. Once, a few residents poured out the water from their flower pots (where the big mosquito babies were living), which killed the big mosquito babies, because they didn’t know those babies were actually helping control the bad mosquitoes. Those baby mosquitoes are a small but important part of protecting the community environment.
Even with these small problems, scientists think this “mosquito vs mosquito” plan is the way to go. They say we should use both methods together to keep mosquito numbers down for a long time without messing up the environment. “We’re not fighting nature here,” a lead researcher said, “We’re working with it to make the places we live, work, and play safer.” The goal is to solve problems not just for now, but in a way that keeps our neighborhoods green and healthy for years to come. This is exactly what we need to do to build a better living space for everyone.
1.What can we learn about the lab-raised male mosquitoes from Paragraph 2?
A.They have passed safety tests and are safe to release in communities.
B.They are the same as wild mosquitoes except for carrying Wolbachia.
C.They are raised in large numbers to bite and kill wild female mosquitoes.
D.They will die after mating with wild female mosquitoes.
2.What can we infer about the “mosquito vs mosquito” plan from Paragraph 4?
A.It is not as effective as using chemical sprays.
B.It needs a lot of money and help from local people.
C.It is only suitable for large cities like Foshan.
D.It will be widely used in China in the near future.
3.What can we learn from the passage?
A.The “mosquito vs mosquito” plan is now being widely used in Foshan.
B.The big, pretty mosquitoes can eat 80 to 100 harmful larvae in their whole life.
C.The “mosquito vs mosquito” plan is a greener way to control mosquitoes than chemical sprays.
D.The lab-raised mosquitoes will finally reduce the number of wild mosquitoes in Foshan.
【答案】1.A 2.B 3.C

Passage 1
(25-26九年级上·北京东城·期中)
Why Do Top Athletes Choke Under Pressure?
According to classic economic theory, the higher the reward, the better the expected performance. As a result, we could expect the best performance at the most important moments. But why do we so often see the most talented and experienced athletes perform much worse than expected in important competitions like the Olympics?
Why the Drop in Performance?
It is not necessarily true that there’s a direct relationship between incentives (激励) and achievement. Research has shown that increased motivation (动机) beyond a certain level harms an athlete’s performance. We call this phenomenon “choking under pressure”. Greater incentives may lead to higher levels of arousal (兴奋). The relationship between performance and arousal looks like an inverted U shape (倒U形), meaning that performance is the best at certain levels of arousal and drops with over-arousal.
The desire to perform as well as possible is thought to create performance pressure. Many studies have shown increased pressure has a bad effect on athletes’ performance in skill-based games. When people overthink or consciously monitor each step, the drop in performance happens.
2
Beyond the pressure coming from the important competitions, another thing that may add pressure is the level of expectations. An experiment suggested high audience expectations harm performance in a skill-based task. For example, one of the most famous biathletes in history, Martin Fourcade, said it was very emotional for him to compete in his home country and also much harder than competing abroad because of greater expectations.
We tested this home disadvantage by using data from biathlon (冬季两项) competitions over 17 years. We have found the most titled athletes miss a lot more shots when competing in their home country compared to when they compete abroad. The most reasonable explanation likely relates to the level of expectations from the homeland.
How to Deal with It?
There are several ways to reduce stress, such as a countdown or taking a deep breath before the task. But the base for any solution is to realize that stress affects performance. Choking under pressure can happen to the best athletes and it’s not a shame to admit it. The more athletes know about the effect pressure can have on them, the more likely they are to succeed at the highest level.
1.What can we learn from “choking under pressure”?
A.The higher the reward, the better the expected performance.
B.Better achievement in games results from a drop in pressure.
C.Arousal beyond a certain level harms an athlete’s performance.
D.Athletes’ performance in games has something to do with their training.
2.Which of the following would be the best heading for Paragraph 4 and 5?
A.Pressure as a Key to Improving Performance.
B.Pressure as a Push for Becoming Top-level Athletes.
C.High Expectations as a Cause of Choking Under Pressure.
D.High Expectations as an Incentive to Compete in the Home Country.
3.To deal with pressure, the athletes should first ________.
A.avoid the possible feelings of pressure
B.share their worries with friends and coaches
C.try their best to succeed at the highest level
D.recognize the effect of stress on performance
【答案】1.C 2.C 3.D
【导语】本文主要讲述了为什么顶尖运动员在压力下会表现不好。
【详解】1.细节理解题。根据“Research has shown that increased motivation (动机) beyond a certain level harms an athlete’s performance.”可知,研究表明,超过一定水平的动机增加会对运动员的表现产生不好的影响。故选C。
2.推理判断题。根据4、5 段所阐述的主要是运动员们在高预期的情况下在比赛中发挥失误的例子。其实就是在告诉我们高预期是造成运动员很大压力,发挥失常的主要原因,故选C。
3.细节理解题。根据“But the base for any solution is to realize that stress affects performance.”可知,解决问题的关键还是需要意识到压力会影响比赛的发挥,故选D。
Passage 2
(25-26九年级上·北京西城·期中)For a long time, people thought that when children became teenagers, parents should step back. But new studies show something different. The teenage years are not a time for parents to be less involved. Instead, they are a time to stay connected, just in new ways.
From Boss to Guide
Parents often act like “managers”. They tell their teens what to do and make all the decisions. However, research now suggests a better role: be a “guide”. A guide does not give orders. A guide offers advice when the teen asks for it. A guide respects that the teenager is becoming more independent but is still there to help. This way, parents use their influence through a strong relationship, not through strict control.
The Growing Teen Brain
Why do teenagers sometimes act unreasonably or have strong mood swings (起伏)? Brain science gives us an answer. The part of the brain that controls good judgment and decision-making is still developing in the teen years. This means that a teen’s sometimes risky or emotional behavior is not just them being difficult—it is a normal part of brain development. Knowing this can help parents be more patient. They can focus on helping their teens learn to make good choices while the brain is still learning how.
What Teenagers Need to Do
Experts say that all teenagers are working on four important tasks as they grow up:
• Be Their Own Person: They want to make their own choices.
• Discover Who They Are: They try out different ideas to find their identity (身份).
• Become More Independent: They naturally create some distance from their parents.
• Make Close Friends: They build strong friendships outside the family.
When parents understand these tasks, they can see their teen’s behavior differently. Arguing about a small rule might really be about the teen’s need for more independence. This new view can reduce fights and help parents support their child’s growth.
One of the most powerful findings is about empathy—the ability to understand and share the feelings of another. Studies show that when teenagers feel understood and listened to by their parents, they are more likely to be understanding and kind to others. Simply listening to a teen’s feelings without immediately judging or solving the problem can build great trust. This kind of connection makes the teenage years easier and helps build a strong, positive relationship for the future.
In summary, these new ideas give parents a more hopeful way to see the teenage years. By being a guide instead of a boss, understanding the teen brain, supporting their growth tasks, and listening with empathy, parents can turn these years into a time of positive growth and a closer bond (联结).
1.According to the passage, which of the following actions best shows the parent’s role as a “guide”?
A.Making a strict daily schedule for the teen to follow.
B.Giving clear instructions on how to solve a problem step by step.
C.Offering advice when the teen needs help with a friendship problem.
D.Telling the teen that his new interest won’t last long and will pass.
2.According to brain science, why do teenagers sometimes have strong mood swings?
A.Because they want to make their parents angry.
B.Because they lack communication with their parents.
C.Because they spend too much time with emotional friends.
D.Because their brain’s area for good judgement is still developing.
3.What is the best heading for Paragraph 6?
A.The Importance of Understanding B.The Power of Listening
C.The Benefit of Connecting D.The Ways of Sharing
4.Which of the following may the writer most likely agree with?
A.Parents should strictly manage their teenagers’ lives to keep them safe.
B.A teenager’s need to make their own choices is a natural part of growth.
C.The main goal of the teenage years is to get good grades for the future.
D.It is hard to build a close bond with teenagers because of their brain.
【答案】1.C 2.D 3.B 4.B
【导语】本文是一篇说明文。文章主要介绍了父母在青少年时期应扮演的角色、青少年情绪波动的原因、青少年成长的任务以及共情倾听的重要性等内容。
【详解】1.细节理解题。根据“A guide offers advice when the teen asks for it.”可知,当青少年在友谊问题上需要帮助时提供建议最能体现父母作为“引导者”的角色,故选C。
2.细节理解题。根据“The part of the brain that controls good judgment and decision-making is still developing in the teen years. This means that a teen’s sometimes risky or emotional behavior is not just them being difficult—it is a normal part of brain development.”可知,青少年有时情绪波动大是因为他们大脑中控制良好判断力的区域仍在发育,故选D。
3.最佳标题题。根据“Studies show that when teenagers feel understood and listened to by their parents, they are more likely to be understanding and kind to others. Simply listening to a teen’s feelings without immediately judging or solving the problem can build great trust.”可知,第六段主要讲倾听的力量,故“The Power of Listening”作为标题最合适,故选B。
4.推理判断题。根据“Be Their Own Person: They want to make their own choices.”可知,青少年需要自己做选择是成长的自然部分,故选B。
Passage 3
(25-26九年级上·北京东城·期中)Recently, some people have complained about the purposefully addictive (上瘾的) designs of smartphones and social media, which make it hard for anyone to put them down, especially teens. Now, a new report in Emotion gives facts that back up what these people said.
According to the report, young people’s life satisfaction and happiness have dropped since 2012, the year the percentage of teens owning smartphones started increasing rapidly. The report also finds that teens’ psychological (心理的) health gets worse the more hours a week they spend on screens.
Jean Twenge is the lead writer of the report. She graphed (制图) the connection between happiness and screen activities, such as social media, texting, gaming, and video chats. She also graphed the connection between happiness and non-screen activities, including sports, reading, and face-to-face communications. She called the relationship between screen and non-screen activities “zero sum”—if you are doing one, it takes time away from the others.
Diane Tanman complains that her sons are like that. They are 11 and 15. They used to play games in fields, and it made them happier. These days, her sons are more into online games. Many of the games have rewards (奖励) built in to keep players coming back. “It’s just junk food for the brain,” Tanman said.
Ed Lazzara says his 12-year-old son Leo is a fan of video games. After playing a lot, Leo gets more upset and uncomfortable. He wants his son to play fewer video games.
However, totally staying away from electronic devices (设备) doesn’t lead to happiness, either. Twenge and her co-writers found that the happiest teens used electronic devices a little less than an hour daily. After a daily hour of screen time, unhappiness rises in relation to increasing screen time.
Spending time in front of a screen is a normal part of being a teenager. Many schools require students to be online and to use iPads or other devices to do their work. But teachers and parents have also complained that technology can get in the way of learning when teens use their devices for things other than their studies.
If we recognize how screen time influences young minds, we can help teens use technology better and protect their psychological health in the process. Screen time is like ice cream. Sure, we can have some once in a while, but it shouldn’t be part of our everyday lives.
1.What can we learn from the passage?
A.Screen time at home is not as beneficial as screen time at school.
B.Nearly an hour of screen time every day makes teens happiest.
C.Technology should be encouraged in classroom learning.
D.What teens do on the screen influences their happiness.
2.Why does the passage give the examples of families with teens?
A.To prove the bad effect of the addictive designs of electronic devices.
B.To show parents have little control over their teens’ screen time.
C.To compare different-aged teens’ feelings about screen use.
D.To explain why electronic devices make teens feel happy.
3.Which of the following would be the best title for the passage?
A.Use of Electronic Devices: Should We Consider Teens’ Needs?
B.Teens’ Psychological Health: Why Is It Important?
C.Screen Time and Teens’ Study Performance
D.Screen Time and Teens’ Life Satisfaction
【答案】1.B 2.A 3.D
【导语】本文是一篇说明文。文章主要介绍了《情感》杂志上的一篇新报告的一些观点,智能手机和社交媒体故意让人上瘾的设计让青少年沉迷于屏幕;青少年每周花在屏幕上的时间越长,他们的心理健康状况就越差,他们的生活满意度和幸福感会有所下降。屏幕时间就像冰淇淋,我们可以偶尔吃一些,但不应该成为我们日常生活的一部分。
【详解】1.细节理解题。根据第六段“Twenge and her co-writers found that the happiest teens used electronic devices a little less than an hour daily.”可知,最快乐的青少年每天使用电子设备的时间略少于一个小时。故选B。
2.细节理解题。根据第四段“Many of the games have rewards built in to keep players coming back. ‘It’s just junk food for the brain,’ Tanman said.”和第五段“After playing a lot, Leo gets more upset and uncomfortable. He wants his son to play fewer video games.”可知,作者列举有青少年的家庭的例子是为了证明电子设备令人上瘾的设计的不良影响。故选A。
3.最佳标题题。综合全文可知,青少年每周花在屏幕上的时间越长,他们的心理健康状况就越差,他们的生活满意度和幸福感会有所下降。选项D“屏幕时间与青少年生活满意度”适合作为文章的标题。故选D。
讲述了三项前沿科技成果:模仿蝠鲼研制的软体潜水器、预测蚊子飞行轨迹的3D模型、可把普通手表变为智能手表的传感器,并分别介绍了它们的功能与用途。
【新素材·三项前沿科技成果】
Manta rays inspire new designManta rays (蝠鲼) have big, flat bodies that help them move well in the water. Chinese scientists have made a soft-body submersible in the same shape as the manta ray. This is the world's first soft-body submersible that looks like a manta ray. With two “eyes”, the submersible can “see” in the dark underwater. One looks ahead to find things, while the other looks to the sides to make a map of the ocean floor. The submersible can work in groups.
________________________
US scientists have made a 3D model to predict how mosquitoes fly. If mosquitoes can only see a target, they fly quickly toward it. If they can't see a target but can smell something like carbon dioxide (二氧化碳), they slow down and move back and forth to stay close. When mosquitoes can both see and smell the target, they fly in a circle around it and get ready to land. These findings could help make better traps (陷阱) to catch mosquitoes.
“Clever” sensor for your watchWith only a sensor (传感器) as small as a coin, your watch can turn into a smartwatch! This sensor is called The Heir and comes from the US. You can use a micro suction disc (微型吸盘) to stick it to the back of most watches. It counts your steps and sends them to an app on your phone. It also vibrates (振动) to tell you when you get calls and messages. You can also play music on your phone by tapping it.
1.In which SECTION of the newspaper can we most likely read the news?
A.LIFE B.ART C.SCIENCE D.SPORTS
2.What do we know about the soft-body submersible?
①shape ②color ③ working way ④ price
A.①② B.①③ C.③④ D.①④
3.What would be a good heading for the second piece of news?
A.Flight Tracks for Mosquito Traps B.New Ways to Catch Mosquitoes
C.Better Traps from Scientists D.Keep Mosquitoes Away
4.What can we infer about the sensor called The Heir?
A.It is very tiny in size. B.It is mainly used to make calls.
C.It needs to be recharged every day. D.It can be used underwater.
5.What does the news above focus on?
A.New discoveries about different animals. B.Success of common people.
C.High-tech products with different purposes. D.Problems in our daily life.
【答案】1.C 2.B 3.B 4.A 5.C
【导语】本文是一篇说明文,主要讲述了三项前沿科技成果:模仿蝠鲼研制的软体潜水器、预测蚊子飞行轨迹的3D模型、可把普通手表变为智能手表的传感器,并分别介绍了它们的功能与用途。
【详解】1.全文三篇短文都介绍科学方面的新发明与研究,因此我们最有可能在报纸的SCIENCE版面读到这几则新闻。
2.第一段指出:“Chinese scientists have made a soft‑body submersible in the same shape as the manta ray…With two ‘eyes’, the submersible can “see” in the dark underwater.”,从中我们可以得知它的shape“外形”以及working way“工作方式”,文中没有提及颜色color和价格price。
3.第二则新闻写道:“These findings could help make better traps (陷阱) to catch mosquitoes.”,科学家通过研究蚊子不同状态下的飞行模式,利用该研究成果帮助制造更好的捕蚊陷阱,代表捕捉蚊子的新途径。
4.第三段写道:“With only a sensor (传感器) as small as a coin”,由硬币一般大小这一句,能够推断出该传感器的体积很小;没有提及打电话用途、每日充电、水下使用的相关描述。
5.三则新闻分别介绍用途各不相同的高科技产品:仿生软体潜水器、蚊子飞行研究模型、手表传感器,所以文章的焦点是用途不同的高科技产品。
