A study found that it works better than running or riding a bike. Tai Chi is 52% better at reducing high blood pressure than regular exercises like running or swimming. Scientists from the China Academy of Chinese Medical Sciences looked at 324 people who had slightly (轻微的) high blood pressure. They divided them into two groups. One group did Tai Chi for one hour, four times a week. The other group ran, rode bikes, or swam for the same amount of time. After a year, the scientists saw that the people doing Tai Chi lowered their blood pressure by 10%. The people who exercised in other ways only lowered theirs by 6%. People all over the world practice Tai Chi. They do it for many reasons. It can not only keep their bodies healthy but also relax their minds. Tai Chi is easy and only includes slow and gentle movements. Doing Tai Chi regularly can make you more flexible and stronger. Many people have high blood pressure, but some do not know they have it. A doctor who helped with the study, thinks that everyone should learn about Tai Chi. It is a safe exercise for people of all ages, and it can help reduce heart problems. 1．What is Tai Chi mainly known for? A．Increasing heart rate. B．Making people run faster. C．Improving swimming skills. D．Helping lower blood pressure. 2．For how long and how often did the Tai Chi group practice? A．Two hours a week. B．Thirty minutes every day. C．One hour, four times a week. D．One hour, three times a week. 3．What was the result for the Tai Chi group after one year? A．They had no change in blood pressure.

The truth is, math is not just about remembering—it’s about understanding. Here are some tips to help you learn math better. Understand, don’t just memorize. When you learn a new formula, ask yourself why it works. For example, the area of a triangle is 1/2× base× height. Why? Because a triangle is half of a rectangle. Understanding the “why” helps you remember longer and use it in different situations. Practice every day. Math is like a sport—you need to practice to get better. Do a few problems each day instead of many problems at once before a test. This keeps your brain sharp (敏捷的) and helps you remember. Learn from mistakes. When you get a wrong answer, don’t just move on. Find out where you went wrong. Did you misunderstand the question? Did you make a careless mistake? Did you use the wrong formula? Learning from mistakes is the fastest way to improve. Connect math to real life. Math is everywhere! When you shop, work out how much you need to pay. When you cook, find out the right amount of food to use. When you play sports, think about angles (倾斜角度) and speed. Seeing math in real life makes it more interesting and meaningful. Ask questions. If you don’t understand something, ask your teacher or classmates. No question is too silly. Remember, every question you ask brings you one step closer to understanding. Math may seem hard at first, but with the right methods and enough practice, anyone can become good at it. The key is to keep trying and never give up. 1．How many tips does the writer give the readers? A．Three. B．Four. C．Five. D．Six. 2．The writer thinks that a good way to understand a new math formula is to ________. A．ask why it works B．memorize it as soon as possible C．write it down without thinking D．use it to finish difficult problems 3．How does the writer support the idea “Learn from mistakes”? A．By giving examples. B．By asking questions. C．By giving facts and numbers. D．By comparing with other methods. 4．What is the main idea of this passage? A．Math is the most difficult subject in school. B．Students should memorize formulas to do well in math. C．Some useful ways to help learn math better. D．We can find math everywhere in our daily life. Desertification (沙漠化) is a big problem in some parts of China, but people have found many ways to fight it. Here are some methods to control deserts and turn them into green land. First, planting trees and grass is the most common way. Their roots (根) help hold the soil together and stop the sand from moving. For example, the “Green Great Wall” project in northern China has planted millions of trees to stop the spread of deserts. Grass is also planted to cover the sand and stop the wind. Second, using straw checkerboards (草方格) is a smart idea. People lay straw in square shapes on the sand. These squares break the wind and keep the sand from spreading. Over time, plants can grow inside these squares, making the land greener. Third, in dry areas, people use drip irrigation (滴灌) to water plants. Drip irrigation sends water directly to plant roots. It can save water. This helps plants grow even in very dry conditions. Finally, education plays a very vital role. The government has made rules to protect the environment, and schools teach students why it’s important to stop desertification. 1．According to the second paragraph, what’s the main use of tree roots? A．To keep the soil from blowing away. B．To cover the sand and stop the wind. C．To make the soil rich for grass to grow. D．To bring more water to dry areas. 2．What can we learn about straw checkerboards? A．They make the land wetter and warmer. B．They make the desert look more beautiful. C．They provide food for animals in the desert. D．They break the wind and help plants grow. 3．What does the underlined word “vital” in the last paragraph mean? A．Simple. B．Important. C．Serious. D．Popular. 4．What’s the best title for the text? A．Sandstorms in Northern China B．How China Fights Desertification C．The Importance of Planting Trees D．The Problems of Desertification in China 提升培优限时练5篇，建议用时25分钟，实际用时 分钟 ①China’s polar research icebreaker Xuelong (Snow Dragon) finished the main missions (任务) in the Amundsen Sea and Ross Sea on Feb 20, 2026, marking a key milestone in the 42nd Antarctic Expedition (南极考察). On November 1, 2025, China’s 42nd Antarctic Expedition team set sail from Shanghai. They have to carry out a seven-month mission, supported by the country’s two icebreakers, Xuelong and Xuelong 2. ②Among its many tasks, the team drilled (钻孔) and collected samples (样本) from under an ice sheet (冰盖) more than 3,000 meters thick for scientific research on Antarctica. They also tested new machines, such as the Snow Leopard 6×6 wheeled vehicle, which was designed and built in China. ③For over 40 years, China has been exploring Antarctica and achieving plenty of firsts. Its very first expedition team set off in November 1984, also from Shanghai. Three months later, China’s first Antarctic research base, the Great Wall Station, was built. In 1994, China’s first icebreaker, Xuelong, entered service. Since then, it has travelled to Antarctica 31 times! ④In 2005, the 21st expedition team climbed all the way to Dome A (冰穹A), the highest point of the Antarctic ice sheet. It was the first time in history anyone had reached it from the ground. The list of big moments like these goes on and on. ⑤You might ask why we keep going back to Antarctica. Well, it’s the key to understanding how our planet works—especially the climate and environment. There is also a record showing what our planet was like over the past million years. ⑥“Continuously improving our ability to understand, protect, and use Antarctica is a requirement for China to build itself into a strong oceanic nation,” said Long Wei, deputy director of the Chinese Arctic and Antarctic Administration (南北极管理局). ⑦Antarctica is like the Earth’s history book. It’s also where our planet’s past and future meet. As the 42nd expedition has set sail, it carries with it a deeper sense of responsibility for the Earth’s future. 1．What is one of the main scientific tasks of China’s 42nd Antarctic expedition? A．Building a new research base on the ice sheet. B．Testing a new icebreaker for future sails. C．Climbing to the highest point of Dome A again. D．Drilling and collecting samples under the thick ice. 2．What can we infer from this passage? A．China’s expedition team has the best icebreaker (Xuelong) in the world. B．China’s first expedition team set off and built its research base before 1984. C．Antarctic Expedition only helps us study the climate of the Earth. D．China will play a more important role in exploring and saving the Earth. 3．Which of the following shows the structure of this passage? A． B． C． D． 4．What is the writer’s main purpose of writing this passage? A．To explain how to drill through thick ice sheets and do research. B．To describe how cold and dangerous Antarctica is for the team. C．To tell readers the history and research experiences of icebreakers in the world. D．To show China’s efforts in Antarctic research and the importance of Antarctica. Now the world has a population of over 8 billion. Some people may worry that the world’s population will just keep growing. Will that be the case? The findings from a study published (出版；刊登) in a famous journal The Lancet in December, 2021 might surprise many people. It predicted that the world’s population would decrease (减少) in the next century. Experts believe the world’s population will reach around 9.7 billion by 2064 before slowing down to about 8.8 billion by the end of the 21st century. Stein Emil Vollset, the leader of the study, is a professor at the Department of Health Metrics Sciences at the University of Washington School of Medicine. “If the prediction is correct, for the first time, we will see the world’s population decrease because of a low birth rate (生育率),” he said. Because of the low birth rate and the aging population, up to 23 countries and areas, including Japan and Italy, may see their populations decrease by more than 50 percent by the end of the 21st century. China has the largest population in the world now. But its population will also decrease from 1.4 billion to about 732 million by 2100. 1．The underlined world “It” in the second paragraph refers to ________. A．the study B．the population C．a popular book D．a famous magazine 2．What will the world’s population be by the end of the 21st century according to the passage? A．About 732 million. B．About 1.4 billion. C．About 8.8 billion. D．About 9.7 billion. 3．What does the passage mainly talk about? A．What the world’s population will be by 2030. B．How many children people want to have now. C．Experts study how to control the world’s population. D．The world’s population will slow down in the future. If you have problems describing people, don’t worry! We’ll use popular film characters (角色) to help you learn some useful words. Naive Meaning: If someone is naive, they have little experience and believe good things will always happen.

The trial, which began in 2018, involved five people between the ages of 22 and 60. They all had problems that were related to mental activities like thinking or reasoning after having serious brain injuries for 3 years or more. The injuries meant they had difficulty performing some tasks. For the trial, doctors implanted (植入) a tiny device into each patient’s brain during an operation. The device used “deep brain stimulation” (DBS), which rebuilds connections between neurons. Neurons are tiny cells, and there are billions of them in the brain. Whenever you do something, chemical and electrical signals move between your neurons. The tiny device applied electricity to parts of the brain. The trial was the first to focus DBS on a part of the brain that deals with consciousness (意识). It helped people be aware of what is around them and be able to respond (作出反应) to it. After the devices were put into the brains, the patients in the study had them turned on for 90 days, for 12 hours a day. This had a great influence on their lives. They could suddenly do things, like reading a book or playing video games, that used to be impossible because of their brain injuries. They also reported feeling less tired and could get through the day without napping. After 90 days, researchers wanted to turn off some of the patients’ devices. Two people were so happy with the difference the device made in their lives that they refused. Finally, one person agreed to have their devices turned off—and their brain performance got worse. Gina Arata, a patient who took part in the trial, said, “I can remember how much money is in my bank account. I wasn’t able to read, but after the implant I bought a book... and loved it and remembered it.” Nicholas Schiff, one of the authors of the study, called it a “pioneering moment.” Scientists hope the implant will change the lives of more people with serious long-term brain injuries. 1．Which of the following is TRUE about the patients in the trial? A．They have problems with mental activities. B．The patients include both children and adults. C．Only four patients are invited to be in the trial. D．All of them get injured almost at the same time. 2．Which is NOT mentioned as a result of using the device? A．Patients will feel less tired than before. B．Patients will have more need for napping. C．Patients may have the ability to read books. D．Patients’ memory for daily tasks will be better. 3．What is the right order of the following steps of the trial? a. Researchers tried to turn off some patients’ devices. b. Doctors implanted tiny devices into patients’ brains. c. Patients had their devices turned on for 12 hours daily. d. Two patients refused to let researchers turn off the device. e. Patients showed improved cognitive abilities like reading. A．a-b-c-e-d B．a-b-d-e-c C．b-c-e-a-d D．b-e-c-a-d 4．Which is the best title for this article? A．Brain Surgery Risks: A Patient’s Story B．The Way Neurons Send Signals in the Brain C．A New Device for Patients with Brain Injuries D．A New Discovery of A Cure For All Brain Injuries Tofu, the soft white food made from soybeans (大豆), has a fascinating history that began in ancient China. According to legend, it was invented over 2,000 years ago by a Prince of Huainan named Liu An. Some say he discovered it by accident while making medicine, while others believe he created it as a kind of healthy food for his sick mother. In ancient China, tofu quickly became very popular. People considered it one of their most important foods. Chinese people developed many cooking methods for tofu, making it a key part of their food culture. When tofu spread to Japan around 700 AD, it became so popular during the Edo period that people even created a funny folk story. As it traveled to other Asian countries, each region developed its own special tofu dishes—Koreans made spicy tofu stew, Indonesians created fried tofu with peanut sauce, and Vietnamese invented fresh tofu salads. ▲ First, it’s packed with protein and nutrients (营养素), making it very healthy. Second, it’s affordable for most people. It’s much cheaper than meat but just as nutritious. Third, its mild taste allows it to be cooked in countless ways—fried, boiled, baked or eaten raw. These wonderful qualities explain why tofu has become a beloved food worldwide. The story of tofu shows how this simple food can travel across countries and cultures. From its accidental discovery in China to becoming a favorite in different countries, tofu’s journey teaches us how good ideas can spread and adapt to different places. 1．Who invented tofu according to the ancient Chinese legend? A．A doctor. B．A prince. C．A farmer. D．A mother. 2．Which of the following can be best put in “ ▲ ” in Paragraph 4? A．What makes tofu so popular? B．What role does tofu play? C．How can people cook tofu?

D．Inexpensive. 4．The main purpose of the text is to ________ A．teach how to make tofu B．advertise tofu products C．explain tofu’s journey D．compare different Asian foods 满分冲刺限时练5篇，建议用时30分钟，实际用时 分钟 Nowadays, kids may ask, “Before smart phones came out, what did people do when they got lost?” They are not just curious—they are exploring how phone culture is changing the way we think, feel, and act in the digital (数字的) age. In this digital age, kids have no experience of a “pre-Internet mindset (前互联网思维模式)”. In the past, when we faced uncertainties, like not knowing the shortest path, or the answer to a question, we couldn’t get information easily like we do today. At that time, our brains had to adapt (适应) to that discomfort. We depended on our memory and came up with creative solutions. These cognitive (认知的) “workouts” strengthened attention and problem-solving skills. Now, with the wide use of phones and the Internet, answers come quickly. There’s less need to memorize routes or struggle through problems alone. This change makes many people worry about technology’s negative influence, and some even fall into a “deficit mindset”, believing everything was better in the past. For example, they might think writing letters is far better than messaging, while overlooking the amazing efficiency and connectivity that technology brings. It’s true that some studies suggest heavy social media use can challenge our focus. Even a short screen time affects brain areas for self-control and decision-making. But this isn’t the whole story. New research, like a 2023 study on young adults, shows that technology also trains our brains in different ways. When dealing with new things, it easily connects us with different topics and cultures, making our minds more open and adaptable. Therefore, instead of gainsaying the advantages that are brought about by the digital age, we should recognize the natural adaptation of the human brain. In fact, people have developed the following three basic modes of thinking to deal with problems today: The Deep-Thinking Mode The Quick-Learning Mode The Free-Switching Mode Disconnecting from digital tools to develop your own ideas and building creativity that AI cannot easily provide. Using technology as a tool to get information, solve problems effectively, and keep up with the latest knowledge. Switching between the two modes according to your tasks and using digital tools wisely only when they help you achieve your goals. Next time you face a problem, notice your natural response. Do you stand the uncertainty, reach for your phone, or find a middle path? There is no single “right” way to think, for each mode offers unique advantages that our complex world needs. Understanding how your mind has adapted to our digital environment might just be your greatest strength. 1．Why does the writer mention the kids’ question in Paragraph 1? A．To present kids’ curiosity about the past life. B．To highlight the importance of phone culture. C．To stress the benefits that are brought by smart phones. D．To start the discussion of the influence of the digital age. 2．What does the word “gainsaying” in Paragraph 5 probably mean? A．sticking to B．speaking against C．giving in to D．putting up with 3．Which of the following would the writer most probably agree with? A．Curiosity encourages people’s lifelong learning. B．Using social media develops decision-making skills. C．Recognizing cognitive strengths helps solve problems. D．A “deficit mindset” improves efficiency and connectivity. 4．Which of the following would be the best title for the passage? A．The Influence of Digital World Over Attention B．The Workout of Our Brain to Remain Creative C．The Adaptation of Our Brain to the Digital Age D．The Changes of Pre-and After-Internet Environment The Trap (陷阱) of the Deadline High You’ve probably said it or heard it: “I work better under pressure.” It feels true because when the deadline draws near-for example, you must hand in a task tomorrow-your brain runs fast. That last-minute rush can feel productive but it’s not increased performance. It’s rushed performance to make up for weeks of avoidance and inaction. Procrastinating (拖延) then rushing to finish a task isn’t about time management. It’s about emotion regulation (调节). When a task feels uncertain or unpleasant, your brain looks for a way out. Behind this situation is a fight between two brain areas. The limbic system wants comfort right now. The prefrontal cortex wants long-term success. But the limbic system can be faster and stronger. So unless you intervene on purpose, the part of your brain that prefers comfort to challenge will usually win. What’s worse, there are long-term costs to procrastination. At first, you feel a weight off your shoulders. But studies show that over time, procrastinators experience more stress, worse health, and lower performance. That deadline high? It’s the trap. It rewards the brain for procrastinating, making you more likely to depend on panic again next time. So, how can you break this cycle without depending on pressure? Explore the task that scares you with the Triple Check tool. Procrastination is a disguise (伪装), whether that’s fear of failure, judgment, or discomfort. Use the Triple Check tool to ask yourself some questions with curiosity. Then you can figure out why you procrastinate, so you can regain a sense of control. Start small to regain drive. Promise yourself to just 10 minutes of focused work. Still having trouble getting started? Start your task with a small one- “sit in front of the desk” or “write one sentence.” Add “micro-costs” for avoidance. Want to scroll? Make it inconvenient. Sign out, or put your phone in another room. These micro-costs can bring you enough time to think rationally (理智地). Each time you choose action over avoidance, you’re not just checking off a to-do, you’re teaching your brain to not depend on the deadline high. And there’s no need for self-blame (自我谴责) in that process- just curiosity. 1．What would the writer most probably agree with about the last-minute rush? A．It is quite productive. B．It is one kind of avoidance. C．It is about time management. D．It is about emotion regulation. 2．What does the word “intervene” in Paragraph 3 most probably mean? A．Pay no attention to the problem. B．Wait for the right moment. C．Follow your first feeling. D．Step in and take actions. 3．What is the best example of breaking the cycle of the deadline high? A．Push yourself to finish the task at once without stopping. B．To begin with, focus on your homework for just 10 minutes. C．Listen to music while doing your homework to make you relaxed. D．Refuse to begin difficult homework because you fear making mistakes. 4．What is the writer’s main purpose in writing this passage? A．To warn readers of the effect of the deadline high. B．To encourage readers to work when they feel pressure. C．To advise readers to break from the deadline high. D．To remind readers not to be afraid of difficult tasks. Most people connect running with speed, seeing it as an exercise that leaves runners breathless and tired when they finish. So, when someone runs slowly, they might feel like they’re not putting in enough effort. However, different running styles have different advantages. ▲ One style of slow running that has recently been popular is running at a niko niko pace. Niko niko running was developed by Hiroaki Tanaka, a Japanese professor. The name niko niko, which means “smile” in Japanese, perfectly explains this running style. Instead of pushing yourself through hard exercise, niko niko running wants you to exercise while enjoying yourself. Dr. Tanaka spent years improving niko niko running. The general rule is that people run at an intensity (强度) below 50% of their VO2 max, which means the amount of oxygen (氧气) our bodies use during exercise. For most people, this pace is just a little faster than walking. Jogging at the niko niko pace should make it possible for people to carry on a conversation easily. Besides its slow speed, keeping proper posture (姿势) is important in niko niko running. This requires taking shorter, quicker steps—about 180 per minute—and landing on the mid-foot rather than the heel (脚后跟). Dr. Tanaka recommends that people stand tall while jogging with their backs straight and shoulders relaxed. Of course, people should jog with smiles on their faces. Running at a niko niko pace allows people to run for long periods without getting tired. Exercising over long periods can make us feel energetic and keep us in a good mood. Next time you go for a run, try slowing down and jogging at the niko niko pace. You might just end the run with a smile on your face. 1．Which of the following sentences is the most suitable for ▲ in paragraph 1? A．You need to pick a proper running style based on your physical condition. B．Fast running is still the most useful way to build up physical strength. C．Slow running can hardly bring any real advantages to runners. D．Slow running can be a good choice for your running plan. 2．What can we learn about niko niko running? A．It requires runners to run as slowly as they can. B．It allows runners to talk easily while jogging at this pace. C．It was created to help runners improve their speed quickly. D．Its intensity is over 50% of runners’ VO2 max in most cases. 3．Which of the following pictures shows the proper posture in niko niko running? A． B． C． D． 4．What's the main purpose of the article? A．To introduce a popular slow running style. B．To compare fast running and slow running. C．To tell us how to improve running speed and posture. D．To explain why Dr. Tanaka developed new running styles. Listening to music, watching movies, reading novels... Which kind of art is your go-to choice for fun? According to a new study, art not only calms your mind but also improves your physical health. For the first time, scientists in the UK found that art helps the immune (免疫的), endocrine (内分泌的) and nervous systems all at once, said The Guardian. The study included 50 healthy volunteers aged 18 to 40. Half of them went to see real artworks at the Courtauld Gallery in London, while the other half looked at copies of the same paintings in a non-gallery setting. All of them wore health sensors throughout the experiment. The result showed a 22 percent drop in stress hormones (激素) for the gallery-goers and an 8 percent drop for the other group, according to Art Fund. Signs of inflammation (炎症) also went down by about 30 percent for the gallery group. It’s not just visual art that has such effects. For example, a 2021 Swiss study said that dance reduces stress by improving movement control. What makes art so powerful? Scientists have different ideas. One, developed by Edward Vessel at the City College of New York, looks to our brain’s default mode network (默认模式网络). This network is thought to play a key role in creativity—it usually stays quiet when we pay attention to things around us. But when we enjoy art, this network becomes active. Although we are still learning how this works, ________. According to American Scientist, art therapy was first developed to help traumatized (心理受创的) World War II soldiers express their feelings. Those painful experiences often hurt the parts of their brains that control speech, so traditional talking therapy didn’t work well. Since then, art therapy has helped over 650 million people around the world. Marygrace Berberian, a professor at New York University, said in the university’s news in September that number-based studies, like the new UK study, can help more people get art therapy. 1．What does the result of the UK study show? A．Young people benefit more from viewing art. B．Looking at art copies is of little benefit to health. C．Painting is the most helpful art for lowering stress. D．Stress went down more for the gallery-goers group. 2．What does Edward Vessel’s theory suggest about art? A．It makes people’s memory become better. B．It makes the brain’s special network active. C．It makes the brain’s usual activity weaker. D．It makes people careless about the outside. 3．Which of the following is the most suitable for ________? A．art’s power has long been used in treatment B．art’s power is still doubted by scientists C．art’s power has been fully understood by scientists D．art’s power hasn’t been used in treatment till now 4．How does the writer develop the passage? A．By describing research steps. B．By offering interesting ideas. C．By using many examples. D．By listing different art forms The average person eats about 40 kg of meat per year. In developed countries, it’s double that—about the same weight as an adult dolphin. But experts now advise cutting down the amount of meat we eat to help slow down the warming of the Earth. So, here’s a thought experiment: what if the whole world turned vegan (eating no animal products at all)? Around 15% of all greenhouse gases produced by humans come from raising farm animals. If we all become vegan, these gases will be slashed. Eating meat takes up space—a lot of it. Around 80% of all farmland is used for producing meat and milk products. This area is almost as large as Europe, the United States, China, and Australia put together. Meat and milk usually give us only 18% of the energy we need, but they cause 60% of the harmful gases from farming. A report by the UN’s climate body, the IPCC, recommends we all reduce the amount of meat we eat, and also how much we waste. The report has found that 8%—10% of the world’s harmful gases come from lost or wasted food. ▲ Large-scale (大规模) farming of cows causes especially serious harm and has been a big factor in the loss of the Amazon Rainforest. When cows digest (消化) their food, they produce methane (CH4)—a powerful greenhouse gas that is about 28 times more powerful than carbon dioxide (CO2) over 100 years. One cow lets out between 70 and 100 kg of methane every year, and there are around 1.5 billion cows in the world today. But small-scale farming of animals can have a lower environmental footprint, and sometimes—as with traditional grazing (放牧)—can even help wildlife and plants live together. Vegan alternatives (替代) also come with their own problems. For example, large-scale bean production can cause forests to be cut down, and almond (杏仁) production requires huge amounts of water. If everyone changed to a plant-based diet, it could bring important health benefits. One study guessed that if everyone ate a vegan diet—rich in fresh fruit and vegetables—around eight million deaths could be avoided worldwide by 2050. There are no simple answers. If everyone changes how they view food, produce it, and eat it in a green way, we might change the world. 1．What does “be slashed” in Paragraph 1 most probably mean? A．Double. B．Remain. C．Reduce greatly. D．Increase slightly. 2．Which of the following is TRUE according to the passage? A．Raising cows especially harms the Earth. B．A vegan world would end food waste. C．Small farms are more harmful to the Earth. D．Bean production needs plenty of water. 3．Which of the following is the most suitable for ▲ ? A．Raising sheep also harms the Earth. B．Many countries begin raising fewer cows. C．People must stop eating beef at once. D．Not all farming influences the Earth equally. 4．This passage is mainly about ________. A．why cows mainly cause the warming of the Earth B．why we should stop eating meat to protect the Earth C．how eating meat harms the Earth and what we can do D．what the advantages of eating fruits and vegetables are 2 迎战新中考，备考有方向，冲刺有重点！ 1 迎战新中考，备考有方向，冲刺有重点！ 学科网（北京）股份有限公司 $ 备战2026年重庆中考英语押题预测系列，本地名师甄选！ 备战2026年重庆中考英语押题预测系列，本地名师甄选！ 专题04 阅读理解之说明文热点练15篇 （好题速递） 【选题说明：90%选自最新模考/外刊/改编/热点；内容预览：3类限时训练共15篇；难度：易中难】   押   题   预   测 基础入门限时练5篇，建议用时20分钟，实际用时 分钟 When someone’s heart suddenly stops, we can use an AED to save him or her.

They spend hours memorizing formulas (公式) but still make mistakes in exams. The truth is, math is not just about remembering—it’s about understanding. Here are some tips to help you learn math better. Understand, don’t just memorize. When you learn a new formula, ask yourself why it works. For example, the area of a triangle is 1/2× base× height. Why? Because a triangle is half of a rectangle. Understanding the “why” helps you remember longer and use it in different situations. Practice every day. Math is like a sport—you need to practice to get better. Do a few problems each day instead of many problems at once before a test. This keeps your brain sharp (敏捷的) and helps you remember. Learn from mistakes. When you get a wrong answer, don’t just move on. Find out where you went wrong. Did you misunderstand the question? Did you make a careless mistake? Did you use the wrong formula? Learning from mistakes is the fastest way to improve. Connect math to real life. Math is everywhere! When you shop, work out how much you need to pay. When you cook, find out the right amount of food to use. When you play sports, think about angles (倾斜角度) and speed. Seeing math in real life makes it more interesting and meaningful. Ask questions. If you don’t understand something, ask your teacher or classmates. No question is too silly. Remember, every question you ask brings you one step closer to understanding. Math may seem hard at first, but with the right methods and enough practice, anyone can become good at it. The key is to keep trying and never give up. 1．How many tips does the writer give the readers? A．Three. B．Four. C．Five. D．Six. 2．The writer thinks that a good way to understand a new math formula is to ________. A．ask why it works B．memorize it as soon as possible C．write it down without thinking D．use it to finish difficult problems 3．How does the writer support the idea “Learn from mistakes”? A．By giving examples. B．By asking questions. C．By giving facts and numbers. D．By comparing with other methods. 4．What is the main idea of this passage? A．Math is the most difficult subject in school. B．Students should memorize formulas to do well in math. C．Some useful ways to help learn math better. D．We can find math everywhere in our daily life. 【答案】1．C 2．A 3．B 4．C 【导语】本文主要介绍了一些帮助学生更好地学习数学的有用方法。 1．细节理解题。根据“Understand, don’t just memorize.”、“Practice every day.”、“Learn from mistakes.”、“Connect math to real life.”、“Ask questions”可知，作者给了读者五条建议。故选C。 2．细节理解题。根据“When you learn a new formula, ask yourself why it works.”可知，作者认为理解新数学公式的好方法是问其为什么有效。故选A。 3．推理判断题。根据“Find out where you went wrong. Did you misunderstand the question? Did you make a careless mistake? Did you use the wrong formula? ”可知，作者说明该观点时，连续提出三个问题引导读者分析错误的可能原因，以此阐述如何从错误中学习，是通过提问的方式支撑观点。故选B。 4．主旨大意题。文章先指出学生学数学的现状，接着给出学习数学的建议，所以主旨是介绍帮助更好学习数学的有用方法。故选C。 Desertification (沙漠化) is a big problem in some parts of China, but people have found many ways to fight it. Here are some methods to control deserts and turn them into green land. First, planting trees and grass is the most common way. Their roots (根) help hold the soil together and stop the sand from moving. For example, the “Green Great Wall” project in northern China has planted millions of trees to stop the spread of deserts. Grass is also planted to cover the sand and stop the wind. Second, using straw checkerboards (草方格) is a smart idea. People lay straw in square shapes on the sand. These squares break the wind and keep the sand from spreading. Over time, plants can grow inside these squares, making the land greener. Third, in dry areas, people use drip irrigation (滴灌) to water plants. Drip irrigation sends water directly to plant roots. It can save water. This helps plants grow even in very dry conditions. Finally, education plays a very vital role. The government has made rules to protect the environment, and schools teach students why it’s important to stop desertification. 1．According to the second paragraph, what’s the main use of tree roots? A．To keep the soil from blowing away. B．To cover the sand and stop the wind. C．To make the soil rich for grass to grow. D．To bring more water to dry areas. 2．What can we learn about straw checkerboards? A．They make the land wetter and warmer. B．They make the desert look more beautiful. C．They provide food for animals in the desert. D．They break the wind and help plants grow. 3．What does the underlined word “vital” in the last paragraph mean? A．Simple. B．Important. C．Serious. D．Popular. 4．What’s the best title for the text? A．Sandstorms in Northern China B．How China Fights Desertification C．The Importance of Planting Trees D．The Problems of Desertification in China 【答案】1．A 2．D 3．B 4．B 【导语】本文介绍了中国治理沙漠化的几种方法，包括植树种草、使用草方格、滴灌技术以及教育宣传。 1．第二段介绍植树种草是最常见的方法，并说明树根的作用：“Their roots help hold the soil together and stop the sand from moving.”说明树根的主要作用是防止土壤被吹走。因此选A。 2．第三段介绍草方格的作用：“These squares break the wind and keep the sand from spreading. Over time, plants can grow inside these squares.”说明草方格能防风固沙，帮助植物生长。因此选D。 3．最后一段介绍教育在治理沙漠化中的作用，前文提到政府制定法规、学校开展教育，这些都是重要措施。vital意为“重要的”。因此选B。 4．全文介绍了中国治理沙漠化的多种方法，包括植树种草、草方格、滴灌技术和教育宣传。因此最佳标题应为“中国如何治理沙漠化”。因此选B。 提升培优限时练5篇，建议用时25分钟，实际用时 分钟 ①China’s polar research icebreaker Xuelong (Snow Dragon) finished the main missions (任务) in the Amundsen Sea and Ross Sea on Feb 20, 2026, marking a key milestone in the 42nd Antarctic Expedition (南极考察). On November 1, 2025, China’s 42nd Antarctic Expedition team set sail from Shanghai. They have to carry out a seven-month mission, supported by the country’s two icebreakers, Xuelong and Xuelong 2. ②Among its many tasks, the team drilled (钻孔) and collected samples (样本) from under an ice sheet (冰盖) more than 3,000 meters thick for scientific research on Antarctica. They also tested new machines, such as the Snow Leopard 6×6 wheeled vehicle, which was designed and built in China. ③For over 40 years, China has been exploring Antarctica and achieving plenty of firsts. Its very first expedition team set off in November 1984, also from Shanghai. Three months later, China’s first Antarctic research base, the Great Wall Station, was built. In 1994, China’s first icebreaker, Xuelong, entered service. Since then, it has travelled to Antarctica 31 times! ④In 2005, the 21st expedition team climbed all the way to Dome A (冰穹A), the highest point of the Antarctic ice sheet. It was the first time in history anyone had reached it from the ground. The list of big moments like these goes on and on. ⑤You might ask why we keep going back to Antarctica. Well, it’s the key to understanding how our planet works—especially the climate and environment. There is also a record showing what our planet was like over the past million years. ⑥“Continuously improving our ability to understand, protect, and use Antarctica is a requirement for China to build itself into a strong oceanic nation,” said Long Wei, deputy director of the Chinese Arctic and Antarctic Administration (南北极管理局). ⑦Antarctica is like the Earth’s history book. It’s also where our planet’s past and future meet. As the 42nd expedition has set sail, it carries with it a deeper sense of responsibility for the Earth’s future. 1．What is one of the main scientific tasks of China’s 42nd Antarctic expedition? A．Building a new research base on the ice sheet. B．Testing a new icebreaker for future sails. C．Climbing to the highest point of Dome A again. D．Drilling and collecting samples under the thick ice. 2．What can we infer from this passage? A．China’s expedition team has the best icebreaker (Xuelong) in the world. B．China’s first expedition team set off and built its research base before 1984. C．Antarctic Expedition only helps us study the climate of the Earth. D．China will play a more important role in exploring and saving the Earth. 3．Which of the following shows the structure of this passage? A． B． C． D． 4．What is the writer’s main purpose of writing this passage? A．To explain how to drill through thick ice sheets and do research. B．To describe how cold and dangerous Antarctica is for the team. C．To tell readers the history and research experiences of icebreakers in the world. D．To show China’s efforts in Antarctic research and the importance of Antarctica. 【答案】1．D 2．D 3．A 4．D 【导语】本文以中国第42次南极考察为切入点，介绍了本次科考的任务、中国南极科考的历史成就，分析了持续科考的原因，点明了南极的科学价值与科考承载的地球责任，展现了中国在南极研究中的持续努力与担当。 1．第②段“Among its many tasks, the team drilled and collected samples from under an ice sheet more than 3,000 meters thick for scientific research on Antarctica.”直接说明第42次南极考察的核心任务之一，就是在厚冰盖下钻孔并采集样本。 2．第⑥段“Continuously improving our ability to understand, protect, and use Antarctica is a requirement for China to build itself into a strong oceanic nation”及第⑦段“it carries with it a deeper sense of responsibility for the Earth’s future.”多次提到中国持续提升南极科考能力、肩负对地球未来的责任，可推断中国将在南极探索和保护地球中发挥更重要的作用。 3．段落①②介绍本次南极科考的事实与任务（Fact），段落③④回顾中国南极科考的历史成就（Achievement），段落⑤⑥明持续南极科考的原因与意义（Cause），段落⑦总结科考的责任与使命（Responsibility），对应A。 4．全文先介绍第42次南极考察的事实与任务，再回顾中国科考的历史成就，接着说明科考的意义与原因，最后点明南极的重要性与科考的责任。核心目的是展现中国在南极科考中的持续努力，同时强调南极对理解地球的重要价值。 Now the world has a population of over 8 billion. Some people may worry that the world’s population will just keep growing. Will that be the case? The findings from a study published (出版；刊登) in a famous journal The Lancet in December, 2021 might surprise many people. It predicted that the world’s population would decrease (减少) in the next century. Experts believe the world’s population will reach around 9.7 billion by 2064 before slowing down to about 8.8 billion by the end of the 21st century. Stein Emil Vollset, the leader of the study, is a professor at the Department of Health Metrics Sciences at the University of Washington School of Medicine. “If the prediction is correct, for the first time, we will see the world’s population decrease because of a low birth rate (生育率),” he said. Because of the low birth rate and the aging population, up to 23 countries and areas, including Japan and Italy, may see their populations decrease by more than 50 percent by the end of the 21st century. China has the largest population in the world now. But its population will also decrease from 1.4 billion to about 732 million by 2100. 1．The underlined world “It” in the second paragraph refers to ________. A．the study B．the population C．a popular book D．a famous magazine 2．What will the world’s population be by the end of the 21st century according to the passage? A．About 732 million. B．About 1.4 billion. C．About 8.8 billion. D．About 9.7 billion. 3．What does the passage mainly talk about? A．What the world’s population will be by 2030. B．How many children people want to have now. C．Experts study how to control the world’s population. D．The world’s population will slow down in the future. 【答案】1．A 2．C 3．D 【导语】本文介绍了一项发表在知名期刊《柳叶刀》的研究，该研究颠覆了人们对世界人口持续增长的认知，预测下个世纪世界人口会因低生育率减少，21世纪末全球人口将降至约88亿，包括中国在内的多个国家人口都会出现大幅下降。 1．定位到第二段划线词It所在句“The findings from a study published (出版；刊登) in a famous journal The Lancet in December, 2021might surprise many people.”，根据上下文逻辑，前文引出一项发表在知名期刊的研究，此处It后接动作“预测人口减少”，能够发出该动作的就是前文提到的这项研究，只有A选项符合。 2．定位到第二段最后一句“Experts believe the world’s population will reach around 9.7 billion by 2064 before slowing down to about 8.8 billion by the end of the 21st century.”，原文明确提到21世纪末世界人口约为88亿，对应C选项。 3．通读全文，文章开篇提出人们担心世界人口持续增长，随后引出研究结论：未来世界人口会因低生育率增长放缓甚至减少，核心内容是未来世界人口增长会放缓，D选项符合主旨。 If you have problems describing people, don’t worry!

Following a trial (试验), some patients refused to have their devices turned off. The trial, which began in 2018, involved five people between the ages of 22 and 60. They all had problems that were related to mental activities like thinking or reasoning after having serious brain injuries for 3 years or more. The injuries meant they had difficulty performing some tasks. For the trial, doctors implanted (植入) a tiny device into each patient’s brain during an operation. The device used “deep brain stimulation” (DBS), which rebuilds connections between neurons. Neurons are tiny cells, and there are billions of them in the brain. Whenever you do something, chemical and electrical signals move between your neurons. The tiny device applied electricity to parts of the brain. The trial was the first to focus DBS on a part of the brain that deals with consciousness (意识). It helped people be aware of what is around them and be able to respond (作出反应) to it. After the devices were put into the brains, the patients in the study had them turned on for 90 days, for 12 hours a day. This had a great influence on their lives. They could suddenly do things, like reading a book or playing video games, that used to be impossible because of their brain injuries. They also reported feeling less tired and could get through the day without napping. After 90 days, researchers wanted to turn off some of the patients’ devices. Two people were so happy with the difference the device made in their lives that they refused. Finally, one person agreed to have their devices turned off—and their brain performance got worse. Gina Arata, a patient who took part in the trial, said, “I can remember how much money is in my bank account. I wasn’t able to read, but after the implant I bought a book... and loved it and remembered it.” Nicholas Schiff, one of the authors of the study, called it a “pioneering moment.” Scientists hope the implant will change the lives of more people with serious long-term brain injuries. 1．Which of the following is TRUE about the patients in the trial? A．They have problems with mental activities. B．The patients include both children and adults. C．Only four patients are invited to be in the trial. D．All of them get injured almost at the same time. 2．Which is NOT mentioned as a result of using the device? A．Patients will feel less tired than before. B．Patients will have more need for napping. C．Patients may have the ability to read books. D．Patients’ memory for daily tasks will be better. 3．What is the right order of the following steps of the trial? a. Researchers tried to turn off some patients’ devices. b. Doctors implanted tiny devices into patients’ brains. c. Patients had their devices turned on for 12 hours daily. d. Two patients refused to let researchers turn off the device. e. Patients showed improved cognitive abilities like reading. A．a-b-c-e-d B．a-b-d-e-c C．b-c-e-a-d D．b-e-c-a-d 4．Which is the best title for this article? A．Brain Surgery Risks: A Patient’s Story B．The Way Neurons Send Signals in the Brain C．A New Device for Patients with Brain Injuries D．A New Discovery of A Cure For All Brain Injuries 【答案】1．A 2．B 3．C 4．C 【导语】本文主要介绍了一项通过植入微型设备治疗脑损伤患者的临床试验，该设备显著改善了患者的认知能力。 1．第一段明确指出：“They all had problems that were related to mental activities like thinking or reasoning after having serious brain injuries”，说明试验中的患者都存在认知活动方面的问题。 2．第三段提到患者感觉“less tired”和“could get through the day without napping”，说明使用设备后患者不再需要小睡，因此“more need for napping”与事实相反。 3．第二段提到“For the trial, doctors implanted (植入) a tiny device into each patient’s brain during an operation”，对应b；第三段提到“After the devices were put into the brains, the patients in the study had them turned on for 90 days, for 12 hours a day”，对应c；第三段提到“They could suddenly do things, like reading a book or playing video games”，对应e；第四段提到“After 90 days, researchers wanted to turn off some of the patients’ devices”，对应a；第四段提到“Two people were so happy with the difference the device made in their lives that they refused”，对应d。所以顺序是b-c-e-a-d。 4．全文围绕通过植入微型设备治疗脑损伤患者的临床试验展开，介绍了设备的作用、试验过程及结果，因此最合适的标题是“脑损伤患者的新设备”。 Tofu, the soft white food made from soybeans (大豆), has a fascinating history that began in ancient China. According to legend, it was invented over 2,000 years ago by a Prince of Huainan named Liu An. Some say he discovered it by accident while making medicine, while others believe he created it as a kind of healthy food for his sick mother. In ancient China, tofu quickly became very popular. People considered it one of their most important foods. Chinese people developed many cooking methods for tofu, making it a key part of their food culture. When tofu spread to Japan around 700 AD, it became so popular during the Edo period that people even created a funny folk story. As it traveled to other Asian countries, each region developed its own special tofu dishes—Koreans made spicy tofu stew, Indonesians created fried tofu with peanut sauce, and Vietnamese invented fresh tofu salads. ▲ First, it’s packed with protein and nutrients (营养素), making it very healthy. Second, it’s affordable for most people. It’s much cheaper than meat but just as nutritious. Third, its mild taste allows it to be cooked in countless ways—fried, boiled, baked or eaten raw. These wonderful qualities explain why tofu has become a beloved food worldwide. The story of tofu shows how this simple food can travel across countries and cultures. From its accidental discovery in China to becoming a favorite in different countries, tofu’s journey teaches us how good ideas can spread and adapt to different places. 1．Who invented tofu according to the ancient Chinese legend? A．A doctor. B．A prince. C．A farmer. D．A mother. 2．Which of the following can be best put in “ ▲ ” in Paragraph 4? A．What makes tofu so popular? B．What role does tofu play? C．How can people cook tofu? D．How do people like tofu? 3．What does the underlined word “affordable” most probably mean in Paragraph 4? A．Strong. B．Strange. C．Healthy. D．Inexpensive. 4．The main purpose of the text is to ________ A．teach how to make tofu B．advertise tofu products C．explain tofu’s journey D．compare different Asian foods 【答案】1．B 2．A 3．D 4．C 【导语】本文主要介绍了豆腐的起源以及它的传播和受欢迎程度。 1．第一段第二句“According to…by a Prince of Huainan named Liu An.”指出豆腐是一个叫刘安的淮南王子发明的。 2．第四段空格后从营养、价格、烹饪方式三个方面介绍了豆腐受全世界喜爱的原因，空格是总起句，最合适的内容是“是什么让豆腐这么受欢迎？” 3．划线词后一句提到豆腐比肉便宜很多，可推知affordable意思是“不贵的、买得起的”，和D选项Inexpensive（便宜的）含义一致。 4．全文介绍了豆腐从中国起源，再传播到世界各地，成为全球流行食物的发展过程，最后一段也点明了tofu’s journey，因此本文主要目的是介绍豆腐的发展旅程。 满分冲刺限时练5篇，建议用时30分钟，实际用时 分钟 Nowadays, kids may ask, “Before smart phones came out, what did people do when they got lost?” They are not just curious—they are exploring how phone culture is changing the way we think, feel, and act in the digital (数字的) age. In this digital age, kids have no experience of a “pre-Internet mindset (前互联网思维模式)”. In the past, when we faced uncertainties, like not knowing the shortest path, or the answer to a question, we couldn’t get information easily like we do today. At that time, our brains had to adapt (适应) to that discomfort. We depended on our memory and came up with creative solutions. These cognitive (认知的) “workouts” strengthened attention and problem-solving skills. Now, with the wide use of phones and the Internet, answers come quickly. There’s less need to memorize routes or struggle through problems alone. This change makes many people worry about technology’s negative influence, and some even fall into a “deficit mindset”, believing everything was better in the past. For example, they might think writing letters is far better than messaging, while overlooking the amazing efficiency and connectivity that technology brings. It’s true that some studies suggest heavy social media use can challenge our focus. Even a short screen time affects brain areas for self-control and decision-making. But this isn’t the whole story. New research, like a 2023 study on young adults, shows that technology also trains our brains in different ways. When dealing with new things, it easily connects us with different topics and cultures, making our minds more open and adaptable. Therefore, instead of gainsaying the advantages that are brought about by the digital age, we should recognize the natural adaptation of the human brain. In fact, people have developed the following three basic modes of thinking to deal with problems today: The Deep-Thinking Mode The Quick-Learning Mode The Free-Switching Mode Disconnecting from digital tools to develop your own ideas and building creativity that AI cannot easily provide. Using technology as a tool to get information, solve problems effectively, and keep up with the latest knowledge. Switching between the two modes according to your tasks and using digital tools wisely only when they help you achieve your goals. Next time you face a problem, notice your natural response. Do you stand the uncertainty, reach for your phone, or find a middle path? There is no single “right” way to think, for each mode offers unique advantages that our complex world needs. Understanding how your mind has adapted to our digital environment might just be your greatest strength. 1．Why does the writer mention the kids’ question in Paragraph 1? A．To present kids’ curiosity about the past life. B．To highlight the importance of phone culture. C．To stress the benefits that are brought by smart phones. D．To start the discussion of the influence of the digital age. 2．What does the word “gainsaying” in Paragraph 5 probably mean? A．sticking to B．speaking against C．giving in to D．putting up with 3．Which of the following would the writer most probably agree with? A．Curiosity encourages people’s lifelong learning. B．Using social media develops decision-making skills. C．Recognizing cognitive strengths helps solve problems. D．A “deficit mindset” improves efficiency and connectivity. 4．Which of the following would be the best title for the passage? A．The Influence of Digital World Over Attention B．The Workout of Our Brain to Remain Creative C．The Adaptation of Our Brain to the Digital Age D．The Changes of Pre-and After-Internet Environment 【答案】1．D 2．B 3．C 4．C 【导语】本文探讨了数字时代对人类思维方式的影响，指出大脑会自然适应数字环境，并介绍了深度思考、快速学习和自由切换三种应对问题的思维模式。 1．推理判断题。第一段通过孩子的问题引出话题，进而讨论数字时代对人们思维、感受和行为方式的影响，并非单纯激发孩子们对过去生活的好奇心（A），强调手机文化的重要性（B）或强调智能手机带来的好处（C）。故选D。 2．词义猜测题。根据“instead of gainsaying the advantages that are brought about by the digital age, we should recognize the natural adaptation of the human brain.”可知，我们不应否认数字时代带来的优势，而应认识到人类大脑的自然适应性，“gainsaying”意为“反驳、反对”，与“speaking against”同义。故选B。 3．推理判断题。根据“Understanding how your mind has adapted to our digital environment might just be your greatest strength.”可知，了解你的大脑是如何适应我们这个数字化环境的，或许正是你最大的优势所在，由此可知，选项C“认识到认知优势有助于解决问题”与作者的想法相符。故选C。 4．最佳标题题。全文主线为“大脑对数字时代的适应”：第二段对比过去认知方式，第三段转折指出技术变革，第四段辩证分析影响，第五段提出三种适应模式，末段总结适应性是优势。C项“大脑对数字时代的适应”精准覆盖核心。故选C。 The Trap (陷阱) of the Deadline High You’ve probably said it or heard it: “I work better under pressure.” It feels true because when the deadline draws near-for example, you must hand in a task tomorrow-your brain runs fast. That last-minute rush can feel productive but it’s not increased performance. It’s rushed performance to make up for weeks of avoidance and inaction. Procrastinating (拖延) then rushing to finish a task isn’t about time management. It’s about emotion regulation (调节). When a task feels uncertain or unpleasant, your brain looks for a way out. Behind this situation is a fight between two brain areas. The limbic system wants comfort right now. The prefrontal cortex wants long-term success. But the limbic system can be faster and stronger. So unless you intervene on purpose, the part of your brain that prefers comfort to challenge will usually win. What’s worse, there are long-term costs to procrastination. At first, you feel a weight off your shoulders. But studies show that over time, procrastinators experience more stress, worse health, and lower performance. That deadline high? It’s the trap. It rewards the brain for procrastinating, making you more likely to depend on panic again next time. So, how can you break this cycle without depending on pressure? Explore the task that scares you with the Triple Check tool. Procrastination is a disguise (伪装), whether that’s fear of failure, judgment, or discomfort. Use the Triple Check tool to ask yourself some questions with curiosity. Then you can figure out why you procrastinate, so you can regain a sense of control. Start small to regain drive. Promise yourself to just 10 minutes of focused work. Still having trouble getting started? Start your task with a small one- “sit in front of the desk” or “write one sentence.” Add “micro-costs” for avoidance. Want to scroll? Make it inconvenient. Sign out, or put your phone in another room. These micro-costs can bring you enough time to think rationally (理智地). Each time you choose action over avoidance, you’re not just checking off a to-do, you’re teaching your brain to not depend on the deadline high. And there’s no need for self-blame (自我谴责) in that process- just curiosity. 1．What would the writer most probably agree with about the last-minute rush? A．It is quite productive. B．It is one kind of avoidance. C．It is about time management. D．It is about emotion regulation. 2．What does the word “intervene” in Paragraph 3 most probably mean? A．Pay no attention to the problem. B．Wait for the right moment. C．Follow your first feeling. D．Step in and take actions. 3．What is the best example of breaking the cycle of the deadline high? A．Push yourself to finish the task at once without stopping. B．To begin with, focus on your homework for just 10 minutes. C．Listen to music while doing your homework to make you relaxed. D．Refuse to begin difficult homework because you fear making mistakes. 4．What is the writer’s main purpose in writing this passage? A．To warn readers of the effect of the deadline high. B．To encourage readers to work when they feel pressure. C．To advise readers to break from the deadline high. D．To remind readers not to be afraid of difficult tasks. 【答案】1．D 2．D 3．B 4．C 【导语】本文主要讨论了截止日期前紧张状态的本质、危害以及如何打破这种循环，建议读者通过探索任务、从小事做起、增加回避的“微成本”等方式来摆脱对截止日期前紧张状态的依赖。 1．推理判断题。根据“That last-minute rush can feel productive but it’s not increased performance. It’s rushed performance to make up for weeks of avoidance and inaction.”以及“Procrastinating then rushing to finish a task isn’t about time management. It’s about emotion regulation.”可知，作者认为最后关头的冲刺是一种弥补此前回避和不作为的行为，其本质是关于情绪调节，而非时间管理。故选D。 2．词句猜测题。根据“So unless you intervene on purpose, the part of your brain that prefers comfort to challenge will usually win.”可知，除非你故意介入，否则大脑中偏爱舒适而非挑战的部分通常会获胜。由此可推断出“intervene”意为“介入并采取行动”。故选D。 3．推理判断题。根据“Start small to regain drive. Promise yourself to just 10 minutes of focused work.”可知，作者建议从小处着手，例如承诺只专注于工作10分钟，以此来打破依赖截止日期兴奋的循环。选项B与此建议相符。故选B。 4．主旨大意题。通读全文，特别是结尾段“Each time you choose action over avoidance, you’re not just checking off a to-do, you’re teaching your brain to not depend on the deadline high.”可知，作者主要目的在于分析“截止日期兴奋”的陷阱，并提供具体策略建议读者打破对其的依赖。故选C。 Most people connect running with speed, seeing it as an exercise that leaves runners breathless and tired when they finish. So, when someone runs slowly, they might feel like they’re not putting in enough effort. However, different running styles have different advantages. ▲ One style of slow running that has recently been popular is running at a niko niko pace. Niko niko running was developed by Hiroaki Tanaka, a Japanese professor. The name niko niko, which means “smile” in Japanese, perfectly explains this running style. Instead of pushing yourself through hard exercise, niko niko running wants you to exercise while enjoying yourself. Dr. Tanaka spent years improving niko niko running. The general rule is that people run at an intensity (强度) below 50% of their VO2 max, which means the amount of oxygen (氧气) our bodies use during exercise. For most people, this pace is just a little faster than walking. Jogging at the niko niko pace should make it possible for people to carry on a conversation easily. Besides its slow speed, keeping proper posture (姿势) is important in niko niko running. This requires taking shorter, quicker steps—about 180 per minute—and landing on the mid-foot rather than the heel (脚后跟). Dr. Tanaka recommends that people stand tall while jogging with their backs straight and shoulders relaxed. Of course, people should jog with smiles on their faces. Running at a niko niko pace allows people to run for long periods without getting tired. Exercising over long periods can make us feel energetic and keep us in a good mood. Next time you go for a run, try slowing down and jogging at the niko niko pace. You might just end the run with a smile on your face. 1．Which of the following sentences is the most suitable for ▲ in paragraph 1? A．You need to pick a proper running style based on your physical condition. B．Fast running is still the most useful way to build up physical strength. C．Slow running can hardly bring any real advantages to runners. D．Slow running can be a good choice for your running plan. 2．What can we learn about niko niko running? A．It requires runners to run as slowly as they can. B．It allows runners to talk easily while jogging at this pace. C．It was created to help runners improve their speed quickly. D．Its intensity is over 50% of runners’ VO2 max in most cases. 3．Which of the following pictures shows the proper posture in niko niko running? A． B． C． D． 4．What's the main purpose of the article? A．To introduce a popular slow running style. B．To compare fast running and slow running. C．To tell us how to improve running speed and posture. D．To explain why Dr. Tanaka developed new running styles. 【答案】1．D 2．B 3．C 4．A 【导语】本文主要介绍了慢跑中的一种流行风格——niko niko跑步，包括其起源、规则、姿势以及好处等。 1．推理判断题。根据“One style of slow running that has recently been popular is running at a niko niko pace.”以及后文对niko niko跑步的详细介绍可知，第一段空白处应引出下文要介绍的niko niko跑步这种慢跑方式。选项D“Slow running can be a good choice for your running plan.”(慢跑可以是你跑步计划的一个好选择。)符合语境，引出了慢跑中的一种选择——niko niko跑步。故选D。 2．细节理解题。根据“Jogging at the niko niko pace should make it possible for people to carry on a conversation easily.”可知，以niko niko的速度慢跑应该能让人们轻松地进行对话。故选B。 3．细节理解题。根据“This requires taking shorter, quicker steps—about 180 per minute—and landing on the mid-foot rather than the heel (脚后跟). Dr. Tanaka recommends that people stand tall while jogging with their backs straight and shoulders relaxed. Of course, people should jog with smiles on their faces.”可知，niko niko跑步要求采取更短、更快的步伐，每分钟大约180步，用脚中部而不是脚跟着地，跑步时站直，背部挺直，肩膀放松，脸上带着微笑。选项C的图片符合这一描述。故选C。 4．主旨大意题。通读全文可知，本文主要介绍了一种流行的慢跑方式——niko niko跑步，包括其起源、特点、姿势要求以及带来的好处。故选A。 Listening to music, watching movies, reading novels... Which kind of art is your go-to choice for fun? According to a new study, art not only calms your mind but also improves your physical health. For the first time, scientists in the UK found that art helps the immune (免疫的), endocrine (内分泌的) and nervous systems all at once, said The Guardian. The study included 50 healthy volunteers aged 18 to 40. Half of them went to see real artworks at the Courtauld Gallery in London, while the other half looked at copies of the same paintings in a non-gallery setting. All of them wore health sensors throughout the experiment. The result showed a 22 percent drop in stress hormones (激素) for the gallery-goers and an 8 percent drop for the other group, according to Art Fund. Signs of inflammation (炎症) also went down by about 30 percent for the gallery group. It’s not just visual art that has such effects. For example, a 2021 Swiss study said that dance reduces stress by improving movement control. What makes art so powerful? Scientists have different ideas. One, developed by Edward Vessel at the City College of New York, looks to our brain’s default mode network (默认模式网络). This network is thought to play a key role in creativity—it usually stays quiet when we pay attention to things around us. But when we enjoy art, this network becomes active. Although we are still learning how this works, ________. According to American Scientist, art therapy was first developed to help traumatized (心理受创的) World War II soldiers express their feelings. Those painful experiences often hurt the parts of their brains that control speech, so traditional talking therapy didn’t work well. Since then, art therapy has helped over 650 million people around the world. Marygrace Berberian, a professor at New York University, said in the university’s news in September that number-based studies, like the new UK study, can help more people get art therapy. 1．What does the result of the UK study show? A．Young people benefit more from viewing art. B．Looking at art copies is of little benefit to health. C．Painting is the most helpful art for lowering stress. D．Stress went down more for the gallery-goers group. 2．What does Edward Vessel’s theory suggest about art? A．It makes people’s memory become better. B．It makes the brain’s special network active. C．It makes the brain’s usual activity weaker. D．It makes people careless about the outside. 3．Which of the following is the most suitable for ________? A．art’s power has long been used in treatment B．art’s power is still doubted by scientists C．art’s power has been fully understood by scientists D．art’s power hasn’t been used in treatment till now 4．How does the writer develop the passage? A．By describing research steps. B．By offering interesting ideas. C．By using many examples. D．By listing different art forms 【答案】1．D 2．B 3．A 4．C 【导语】本文介绍研究发现艺术有益身心健康，能降低压力等，还讲述艺术在治疗方面的应用。 1．细节理解题。根据“The result showed a 22 percent drop in stress hormones for the gallery-goers and an 8 percent drop for the other group”可知，去美术馆的那组人压力下降得更多。故选D。 2．细节理解题。根据“But when we enjoy art, this network becomes active.”可知，欣赏艺术时大脑的特殊网络会变得活跃。故选B。 3．推理判断题。根据“According to American Scientist, art therapy was first developed to help traumatized World War II soldiers express their feelings.”可知，艺术的力量长期以来被用于治疗。故选A。 4．推理判断题。根据文中提到英国的研究、瑞士的研究、艺术疗法的例子等可知，作者通过举例来展开文章。故选C。 The average person eats about 40 kg of meat per year. In developed countries, it’s double that—about the same weight as an adult dolphin. But experts now advise cutting down the amount of meat we eat to help slow down the warming of the Earth. So, here’s a thought experiment: what if the whole world turned vegan (eating no animal products at all)? Around 15% of all greenhouse gases produced by humans come from raising farm animals. If we all become vegan, these gases will be slashed. Eating meat takes up space—a lot of it. Around 80% of all farmland is used for producing meat and milk products. This area is almost as large as Europe, the United States, China, and Australia put together. Meat and milk usually give us only 18% of the energy we need, but they cause 60% of the harmful gases from farming. A report by the UN’s climate body, the IPCC, recommends we all reduce the amount of meat we eat, and also how much we waste. The report has found that 8%—10% of the world’s harmful gases come from lost or wasted food. ▲ Large-scale (大规模) farming of cows causes especially serious harm and has been a big factor in the loss of the Amazon Rainforest. When cows digest (消化) their food, they produce methane (CH4)—a powerful greenhouse gas that is about 28 times more powerful than carbon dioxide (CO2) over 100 years. One cow lets out between 70 and 100 kg of methane every year, and there are around 1.5 billion cows in the world today. But small-scale farming of animals can have a lower environmental footprint, and sometimes—as with traditional grazing (放牧)—can even help wildlife and plants live together. Vegan alternatives (替代) also come with their own problems. For example, large-scale bean production can cause forests to be cut down, and almond (杏仁) production requires huge amounts of water. If everyone changed to a plant-based diet, it could bring important health benefits. One study guessed that if everyone ate a vegan diet—rich in fresh fruit and vegetables—around eight million deaths could be avoided worldwide by 2050. There are no simple answers. If everyone changes how they view food, produce it, and eat it in a green way, we might change the world. 1．What does “be slashed” in Paragraph 1 most probably mean? A．Double. B．Remain. C．Reduce greatly. D．Increase slightly. 2．Which of the following is TRUE according to the passage? A．Raising cows especially harms the Earth. B．A vegan world would end food waste. C．Small farms are more harmful to the Earth. D．Bean production needs plenty of water. 3．Which of the following is the most suitable for ▲ ? A．Raising sheep also harms the Earth. B．Many countries begin raising fewer cows. C．People must stop eating beef at once. D．Not all farming influences the Earth equally. 4．This passage is mainly about ________. A．why cows mainly cause the warming of the Earth B．why we should stop eating meat to protect the Earth C．how eating meat harms the Earth and what we can do D．what the advantages of eating fruits and vegetables are 【答案】1．C 2．A 3．D 4．C 【导语】本文是一篇说明文，主要介绍了食用肉类对地球环境的危害（温室气体、土地占用、森林破坏等），同时分析纯素饮食的利弊，并提出绿色饮食的建议。 1．词句猜测题。根据文章第一段“experts now advise cutting down the amount of meat we eat to help slow down the warming of the Earth”以及“Around 15% of all greenhouse gases produced by humans come from raising farm animals. If we all become vegan, these gases will be slashed.”可知，人类产生的温室气体有15%来自养殖牲畜，同时专家建议减少肉类消费以减缓全球变暖，以及“If we all become vegan”这个条件句，可以推断“这些气体”应该会“大幅减少”。故选C。 2．细节理解题。根据文章第三段“Large-scale farming of cows causes especially serious harm and has been a big factor in the loss of the Amazon Rainforest”可知，大规模养奶牛对地球危害尤其严重。故选A。 3．推理判断题。第三段先讲大规模养牛危害极大，后又讲小规模养殖环境影响更低，甚至有助于生态，说明不同养殖方式对地球影响不同。选项D “并非所有农业对地球的影响都相同”可总领全段。故选D。 4．主旨大意题。文章先讲吃肉如何危害地球（温室气体、土地、森林、甲烷），再讲纯素饮食的利弊，最后提出绿色饮食改变世界的做法，因此，文章主要围绕“食用肉类如何危害地球”以及“我们可以做些什么”展开。故选C。 2 迎战新中考，备考有方向，冲刺有重点！ 1 迎战新中考，备考有方向，冲刺有重点！ 学科网（北京）股份有限公司 $
