Is deadwood good or bad for the nature? People often think deadwood is bad because it attracts pests (害虫) that hurt living trees. However, recent studies suggest this risk is low and that deadwood plays a key role in the ecosystem (生态系统). ②According to scientists from Europe and the US, dead trees help nature a lot. On the one hand, dead trees provide homes for fungi (真菌), bacteria (细菌) and insects. As they break down the trees, nutrients (营养物质) are returned to the soil, which helps new plants grow. When this happens, the insects also become food for other animals like birds and bats, making deadwood important for biodiversity (生物多样性). On the other hand, deadwood can help fight climate change by locking some carbon (碳) in the ground for over a century. ③However, deadwood has become less and less all over the world. Many forests have been turned into tree farms where trees are cut down for business use before they die in a natural way. Some people also clear away deadwood to lower the risk of fires or burn it as fuel in factories. ④Scientists believe it is better to leave deadwood where it is. European countries and the US have begun to encourage deadwood preservation (枯木保留区). 根据语篇内容,选择最佳选项。 11．How does the writer lead to the topic? A．By listing numbers. B．By asking questions. C．By telling stories. 12．Which of the following is NOT the advantage of deadwood? A．It can lower the risk of fires. B．It’s important for biodiversity. C．It can help fight climate change. 13．What does “they” in Paragraph 2 refer to (指的是)? A．Fungi, bacteria and insects. B．Animals like birds and bats. C．Scientists from Europe and the US. 14．Why are deadwood becoming less and less these years? A．Because trees live longer and longer. B．Because people don’t plant as many trees as before. C．Because there are more tree farms and people clear away deadwood. 15．What’s the purpose of the passage? A．To explain what deadwood is. B．To tell how important deadwood is. C．To introduce when deadwood appears. 【答案】11．B 12．A 13．A 14．C 15．B 【导语】本文是一篇说明文，通过科学研究纠正“枯木有害”的偏见，阐述枯木在维持生物多样性、促进养分循环及减缓气候变化中的核心作用，呼吁保护森林中自然死亡的树木以维护生态平衡。 11．推理判断题。根据第一段开头两个问题“What happens when a tree dies...? Is deadwood good or bad...?”可知，作者通过提问引入主题。故选B。 12．细节理解题。根据“When this happens, the insects also become food for other animals like birds and bats, making deadwood important for biodiversity (生物多样性). On the other hand, deadwood can help fight climate change by locking some carbon (碳) in the ground for over a century.”可知，枯木的益处包括支持生物多样性、对抗气候变化，而选项A“降低火灾风险”是人们清理枯木的原因，并非枯木本身的优势。故选A。 13．词句猜测题。根据第二段“As they break down the trees...”可知，“they”指代前文“fungi, bacteria and insects”。故选A。 14．细节理解题。根据第三段“Many forests have been turned into tree farms...clear away deadwood”可知，因为有更多的林场，人们清除朽木。故选C。 15．主旨大意题。通读全文可知，全文通过科学证据反驳枯木有害的误解，强调其对生态系统的关键作用，如提供栖息地、促进养分循环、固碳等。故选B。 （25·广西柳州市柳北区鱼峰区联考·二模） Imagine that you get into your car, tell your car where you want to go, and then let it take you there. This is called self-driving. In fact, the idea behind self-driving cars is very simple. A self-driving car is connected with a computer and the computer is connected with many cameras which can track all the objects close to the car and give the computer all the driving rules and routes (路线). Then the car can take people to the place where they want to go. Recently, China has made a big step toward self-driving technology. Since August, driverless taxis can run on roads in Wuhan, Chongqing and Shenzhen. Why do we develop self-driving cars? Self-driving cars give us many benefits. They use computers to sense the things around them. They can help our city make better use of space. That means fewer traffic jams and better parking of cars. For disabled people, self-driving cars can also help them get around more easily. More importantly, with the new technology for safety, self-driving cars could reduce road accidents by 90%. However, self-driving cars aren’t perfect. If something unexpected happens, self-driving cars can’t take action as fast as a human driver. Also, during extreme weather conditions like heavy snow, self-driving cars would fail to see the lines on the road. It might lead to an accident. The car’s computer system could also get hacked (非法入侵) by someone, causing it to break down. It is clear that there is a lot of work to do to make self-driving cars a common and safe sight on our roads. And China is taking the lead in making this happen. 根据语篇内容，选择最佳选项。 16．Which cities have started using driverless taxis since August in China? A．Beijing, Shanghai, Guangzhou. B．Wuhan, Chongqing, Shenzhen. C．Chengdu, Hangzhou, Xi’an. 17．What is the main idea of Paragraph 3? A．The advantages of self-driving cars. B．The dangers of self-driving cars. C．How self-driving cars are built. 18．What does the underlined word “extreme” probably mean? A．奇怪的 B．极端的 C．出乎意料的 19．What can we infer (推断) about self-driving cars from the passage? A．They are now quite safe in all weather conditions. B．They will certainly replace traditional cars. C．They still require solving some technical and safety problems. 20．Where can we most likely read this passage? A．In a storybook. B．In a diary. C．In a magazine. 【答案】16．B 17．A 18．B 19．C 20．C 【导语】本文主要讲述了无人驾驶汽车的发展历程、优点、问题以及未来的发展前景等内容。 16．细节理解题。根据“Since August, driverless taxis can run on roads in Wuhan, Chongqing and Shenzhen.”可知，自8月起，武汉、重庆和深圳的道路上可以行驶无人驾驶出租车。故选B。 17．细节理解题。根据第三段内容可知，本段主要讲述了无人驾驶汽车给我们带来的许多好处，如帮助城市更好地利用空间、减少交通拥堵和更好的停车等。故选A。 18．词句猜测题。根据“Also, during extreme weather conditions like heavy snow, self-driving cars would fail to see the lines on the road.”可知，无人驾驶汽车在像大雪这样的天气条件下可能无法正常工作，由此推知，划线词意为“极端的”，是指像大雪这样极端的天气。故选B。 19．推理判断题。根据“It is clear that there is a lot of work to do to make self-driving cars a common and safe sight on our roads. And China is taking the lead in making this happen.”并结合文章可知，无人驾驶汽车并不是完美的，还存在一些问题和挑战，如遇到意外情况时的反应速度不如人类驾驶员、极端天气条件下无法正常工作以及可能被黑客攻击等。因此，可以推断出无人驾驶汽车仍然需要解决一些技术和安全问题。故选C。 20．推理判断题。通读全文可知， 本文主要讲述了无人驾驶汽车的发展历程、优点、问题以及未来的发展前景等内容，属于科技类文章。因此，最有可能在杂志上读到这篇文章。故选C。 （25·广西南宁市青秀西乡塘良庆区钦州钦北区·二模） Here is a list of some activities that will help kids all year round to explore and learn from the wildness outside your back door or down the road.

That happens when the sunlight goes through the water in the air. The sun shines again after rain, and you see red, orange, yellow, green, blue, indigo and purple light in the sky—a rainbow. The sun’s light is actually made of many colors that don’t all move the same way. When this light goes into a raindrop (雨滴) , it bends (弯曲) and separates into all these colors like red, orange, yellow, green, blue, indigo and purple. After that, these colors hit the back inside of the raindrop and bounce (反弹) back. This makes them bend again and spread out, making a shape like part of a circle, which is the rainbow we see. Purple bends a lot, but red not so much. So, why do rainbows look like a curve? It’s because the raindrops are not all the same distance from us. They make a circle shape around a line from the sun to our eyes, creating that curve. Stand with your back to the sun, because a rainbow appears opposite the sun. If the sun is too high, no rainbow can appear. But sometimes, you might even see two rainbows at once! That’s when the sunlight bounces twice inside the raindrops. Next time you see a rainbow, remember it’s just the sun and rain working together to make something really special and pretty in the sky.根据语篇内容，选择最佳选项。 26．How does the writer start this passage? A．By asking a question. B．By listing numbers. C．By comparing two things. 27．What makes the sunlight show many colors? A．The sun moves very quickly. B．The air near the raindrops gets warm.

We seem to do this more when thinking about a few things at once or doing two things at the same time. For example, you’re crossing the street while chatting with a friend. Some people call this dual-tasking. Everyone does it and we tend to get better at it as we get older and learn new skills. Our brain is like a computer—it can only use so much energy at one time. Think of your brain as a power station providing electricity for cities. If some cities need a lot of energy by having all their lights on, other cities would have less power to work with. There’s only so much electricity to go around. For young kids, dual-tasking is possible. However, it can be a little more difficult for younger kids compared with older kids. Why? The power station in their brain is smaller and can’t produce as much energy as older kids. So why do you sometimes forget to say something before speaking? The answer is that you were likely dual-tasking just before speaking. Maybe you were thinking about the words you wanted to say and something else at the same time. Sometimes your brain can’t do two complicated things at once. You may not have enough energy at that moment. Forgetting things is normal for everyone and can happen when you’re doing too many things. When it happens to you, don’t be nervous! 根据语篇内容，选择最佳选项。 46．How does the writer begin the text? A．By listing numbers. B．By asking questions. C．By showing a saying. 47．What does the underlined word “it” refer to? A．The brain. B．A computer. C．A skill. 48．Why is dual-tasking more difficult for younger kids? A．Because they don’t like to think and talk. B．Because they’re not interested in anything. C．Because their brain’s “power station” is smaller. 49．Which of the following is the “dual-tasking”?

Is deadwood good or bad for the nature? People often think deadwood is bad because it attracts pests (害虫) that hurt living trees. However, recent studies suggest this risk is low and that deadwood plays a key role in the ecosystem (生态系统). ②According to scientists from Europe and the US, dead trees help nature a lot. On the one hand, dead trees provide homes for fungi (真菌), bacteria (细菌) and insects. As they break down the trees, nutrients (营养物质) are returned to the soil, which helps new plants grow. When this happens, the insects also become food for other animals like birds and bats, making deadwood important for biodiversity (生物多样性). On the other hand, deadwood can help fight climate change by locking some carbon (碳) in the ground for over a century. ③However, deadwood has become less and less all over the world. Many forests have been turned into tree farms where trees are cut down for business use before they die in a natural way. Some people also clear away deadwood to lower the risk of fires or burn it as fuel in factories. ④Scientists believe it is better to leave deadwood where it is. European countries and the US have begun to encourage deadwood preservation (枯木保留区). 根据语篇内容,选择最佳选项。 11．How does the writer lead to the topic? A．By listing numbers. B．By asking questions. C．By telling stories. 12．Which of the following is NOT the advantage of deadwood? A．It can lower the risk of fires. B．It’s important for biodiversity. C．It can help fight climate change. 13．What does “they” in Paragraph 2 refer to (指的是)? A．Fungi, bacteria and insects. B．Animals like birds and bats. C．Scientists from Europe and the US. 14．Why are deadwood becoming less and less these years? A．Because trees live longer and longer. B．Because people don’t plant as many trees as before. C．Because there are more tree farms and people clear away deadwood. 15．What’s the purpose of the passage? A．To explain what deadwood is. B．To tell how important deadwood is. C．To introduce when deadwood appears. （25·广西柳州市柳北区鱼峰区联考·二模） Imagine that you get into your car, tell your car where you want to go, and then let it take you there. This is called self-driving. In fact, the idea behind self-driving cars is very simple. A self-driving car is connected with a computer and the computer is connected with many cameras which can track all the objects close to the car and give the computer all the driving rules and routes (路线). Then the car can take people to the place where they want to go. Recently, China has made a big step toward self-driving technology. Since August, driverless taxis can run on roads in Wuhan, Chongqing and Shenzhen. Why do we develop self-driving cars? Self-driving cars give us many benefits. They use computers to sense the things around them. They can help our city make better use of space. That means fewer traffic jams and better parking of cars. For disabled people, self-driving cars can also help them get around more easily. More importantly, with the new technology for safety, self-driving cars could reduce road accidents by 90%. However, self-driving cars aren’t perfect. If something unexpected happens, self-driving cars can’t take action as fast as a human driver. Also, during extreme weather conditions like heavy snow, self-driving cars would fail to see the lines on the road. It might lead to an accident. The car’s computer system could also get hacked (非法入侵) by someone, causing it to break down. It is clear that there is a lot of work to do to make self-driving cars a common and safe sight on our roads. And China is taking the lead in making this happen. 根据语篇内容，选择最佳选项。 16．Which cities have started using driverless taxis since August in China? A．Beijing, Shanghai, Guangzhou.

The sun shines again after rain, and you see red, orange, yellow, green, blue, indigo and purple light in the sky—a rainbow. The sun’s light is actually made of many colors that don’t all move the same way. When this light goes into a raindrop (雨滴) , it bends (弯曲) and separates into all these colors like red, orange, yellow, green, blue, indigo and purple. After that, these colors hit the back inside of the raindrop and bounce (反弹) back. This makes them bend again and spread out, making a shape like part of a circle, which is the rainbow we see. Purple bends a lot, but red not so much. So, why do rainbows look like a curve? It’s because the raindrops are not all the same distance from us. They make a circle shape around a line from the sun to our eyes, creating that curve. Stand with your back to the sun, because a rainbow appears opposite the sun. If the sun is too high, no rainbow can appear. But sometimes, you might even see two rainbows at once! That’s when the sunlight bounces twice inside the raindrops. Next time you see a rainbow, remember it’s just the sun and rain working together to make something really special and pretty in the sky.根据语篇内容，选择最佳选项。 26．How does the writer start this passage?

We seem to do this more when thinking about a few things at once or doing two things at the same time. For example, you’re crossing the street while chatting with a friend. Some people call this dual-tasking. Everyone does it and we tend to get better at it as we get older and learn new skills. Our brain is like a computer—it can only use so much energy at one time. Think of your brain as a power station providing electricity for cities. If some cities need a lot of energy by having all their lights on, other cities would have less power to work with. There’s only so much electricity to go around. For young kids, dual-tasking is possible. However, it can be a little more difficult for younger kids compared with older kids. Why? The power station in their brain is smaller and can’t produce as much energy as older kids. So why do you sometimes forget to say something before speaking? The answer is that you were likely dual-tasking just before speaking. Maybe you were thinking about the words you wanted to say and something else at the same time. Sometimes your brain can’t do two complicated things at once. You may not have enough energy at that moment. Forgetting things is normal for everyone and can happen when you’re doing too many things. When it happens to you, don’t be nervous! 根据语篇内容，选择最佳选项。 46．How does the writer begin the text? A．By listing numbers. B．By asking questions.

And there are a lot of sandstorms coming from it. These sandstorms are very bad for nature and the people living nearby. So, people decided to start a big project to build a green belt around the desert. By the end of 2023,2,761 kilometers of the green belt had been built. In 2024, another 285 kilometers were added. Now, the whole Taklimakan Desert has a green belt around it. The building of this green belt used many different scientific ways. For example, there are tall things to stop the sand, squares made of straw, and long lines of trees. These things work together well to keep the desert from getting bigger. When the green belt around the desert was successfully built, it brought a lot of good things. First, it made the nature around the desert better. There are fewer and weaker sandstorms now. Second, it protected the farming near the desert, so farmers can grow food more easily. Also, the living areas in cities and the countryside are better. Because there are fewer sandstorms, there is less damage(伤害) to things like roads and buildings, and more tourists come. So, local people can make more money.

When ordering a meal from Shake Shack through the Uber Eats app, customers can choose to have their food delivered by a robot. The robot can drive itself from the restaurant to their homes. Customers can then track the robot through their phones. They can see its journey from the restaurant to their addresses. The robot is invented by Serve Robotics.
