Now scientists are looking into a bee’s brain. Clint Perry, a scientist, has spent much time studying how bees think. He says studying bees is not very different from studying other animals. “The main difficulty is to design (设计) an experiment (实验) bee and get what we want,” he says. “With humans, we can ask them a question and get an answer. But we can’t use the same way to get an answer from bees. They are just trying to get sugar. Bees like sugar.” The fact that bees like sugar is helpful for scientists to design experiments. For example, in one experiment, Perry gave bees a task: to find delicious sugar on a landing place above a black bar (棒). Perry made the task easier or harder by moving the landing place farther from or closer to the black bar. He found that bees would avoid the task when it was difficult. And when the task was easy, bees would try it. As for humans, we might choose not to take a test when we weren’t ready for it. And we might choose to take the test when we were well prepared. In the same way, bees seemed to make decisions like humans. Perry points out that we are not sure whether bees actually make a thoughtful choice from experiments. Now scientists still do not know how bees manage to do so much with their tiny brains. But learning more about how bees’ brains work could help us learn more about how our own brains deal with information. 根据语篇内容，选择最佳选项。 1．What did Perry study in his experiments? A．How bees sleep. B．How bees think. C．How bees dream. 2．What can we know from Paragraph 2? A．Bees can talk. B．Bees are lazy. C．Bees like sugar. 3．What would bees do when the task was easy according to Paragraph 3? A．They would try it. B．They would avoid it. C．They would praise it. 4．What’s the importance of looking into bees’ brains? A．It helps us learn how human brains work. B．It tells us how to make thoughtful choices. C．It lets us know how to deal with information. 5．Where is the article probably taken from? A．A travel magazine. B．A sports magazine. C．A science magazine. 【答案】1．B 2．C 3．A 4．A 5．C 【导语】本文是一篇说明文，介绍关于蜜蜂的一些信息。 1．细节理解题。根据“Clint Perry, a scientist, has spent much time studying how bees think.”可知，科学家克林特·佩里花了很多时间研究蜜蜂是如何思考的。故选B。 2．细节理解题。根据“Bees like sugar.”可知，蜜蜂喜欢糖。故选C。 3．细节理解题。根据“And when the task was easy, bees would try it.”可知，当任务很容易时，蜜蜂就会尝试。故选A。 4．细节理解题。根据“But learning more about how bees’ brains work could help us learn more about how our own brains deal with information.”可知，但更多地了解蜜蜂的大脑是如何工作的，可以帮助我们更多地了解人类大脑是如何处理信息的。故选A。 5．推理判断题。本文主要介绍关于蜜蜂的一些信息，所以可能在科学杂志上看到这篇文章，故选C。 Southern white rhinos (犀牛) mainly live in Africa. They are very large in size, about 4 metres long, 1.75 metres high, and over two tons in weight. There are two horns (角) on the nose. The front horn is over half a metre long, while the other one is smaller. Southern white rhinos are not really white. They are grey in colour. “White” may come from the Afrikaans word for “wide”. It has some connection with their wide mouths. Southern white rhinos live on grass, leaves, fruit and so on. They have very poor eyesight. However, they have good hearing and an excellent sense of smell. Their skin (皮肤) is nearly 5 cm thick but is very sensitive. During the day, they try to find a cool place to avoid sunburn. Southern white rhinos lie in mud (泥浆) when they can, as it sticks to their skin and protects them from the bright African sun. Some humans kill rhinos for their horns. They sell horns to those who believe horns have magic powers or can treat sickness. It puts southern white rhinos in danger. Now many actions are taken to protect southern white rhinos. The international trade in rhino horn has been stopped in the world. Besides, many protected areas have been built, especially in South Africa.

It’s an old way to keep people healthy in China, with a history of thousands of years. TCM doctors often check your tongue (舌头), give you herbs (草药), or use acupoints (穴位) to treat illnesses. Now, Artificial Intelligence (AI) is helping TCM work better. AI is smart—it can learn and think like humans, and we can see it in computers and robots. Let’s see how AI helps with TCM herbs first. TCM doctors give people bags of different herbs. People need to boil the herbs in water to make a drink, but it’s hard to get the right temperature and time. A small mistake makes the medicine less useful. But AI machines can solve this problem. They read doctors’ prescriptions and boil herbs in their own ways. They control the temperature perfectly, so the medicine is always good. This saves people a lot of time. AI robots also help with moxibustion (艾灸), a special TCM treatment. Doctors use warmth from burning herbs near your skin to reach acupoints. Finding the right acupoints is very important. AI robots have smart eyes—they can find acupoints quickly. The robot’s arm is steady (稳定的) and never shakes, making the treatment safe. AI is not here to replace TCM doctors. Doctors are still the most important. AI is just a “super assistant” that helps doctors work faster and better, making TCM treatments more efficient for everyone. 根据语篇内容，选择最佳选项。 1．What is TCM according to the passage? A．A new way to make robots smart. B．An old Chinese way to stay healthy. C．A kind of AI machine for treatment. 2．Why is making a TCM herb drink difficult for people? A．Because it takes all day to boil the herbs. B．Because people can’t find enough different herbs. C．Because it’s difficult to get the right temperature and time. 3．What does the underlined word “prescriptions” mean? A．Instructions. B．Tools. C．Records. 4．What helps robots find acupoints quickly from Paragraph 4? A．Their feet. B．Their arms. C．Their smart eyes. 5．What is the main idea of the passage? A．AI machines can boil herbs very quickly. B．AI helps TCM work more efficiently and safely. C．TCM is an old and useful way to keep healthy. 【答案】1．B 2．C 3．A 4．C 5．B 【导语】本文主要介绍了人工智能如何帮助传统中医提高工作效率和治疗安全性。 1．细节理解题。根据“It’s an old way to keep people healthy in China, with a history of thousands of years.”可知，TCM是一种古老的中国保持健康的方法。故选B。 2．细节理解题。根据“People need to boil the herbs in water to make a drink, but it’s hard to get the right temperature and time.”可知，制作中药饮品的困难在于难以控制正确的温度和时间。故选C。 3．词句猜测题。根据“They read doctors’ prescriptions and boil herbs in their own ways.”可知，AI机器人会读取医生的处方，然后按照自己的方式煎药。因此划线词表示“处方”，与Instructions近义。故选A。 4．细节理解题。根据“AI robots have smart eyes—they can find acupoints quickly.”可知，机器人通过智能眼睛快速找到穴位。故选C。 5．主旨大意题。本文主要介绍了人工智能如何帮助传统中医提高工作效率和治疗安全性。故选B。 Ink wash painting (水墨画) is an old and beautiful Chinese art. This special drawing technique (技巧) is created with a brush, dipped into ink, then into water. As you can see, the paintings are created just in black and white. It is said that the technique was invented by an artist named Wang Wei. Ink wash paintings often feature trees, flowers, landscapes, animals, birds and people. Also, they often go with Chinese poems. The painting style does not put high importance on a precise (精确的) description of a real scene or object. They are often improvised (即兴的) works from beautiful scenery. Therefore, this type of painting is hard to copy. Today, there are many new Chinese artists who use the traditional Chinese ink wash technique to draw new scenery and pictures. The first ink wash animation (动画) in China came out in 1960. It’s called Little Tadpole Looking for Mummy. All the animals, plants and rocks in the film are drawn with ink and brush. The film is about 15 minutes long. But it took lots of work. Without computers, the artists had to draw everything by hand. One second of animation needs 24 pictures! Little Tadpole Looking for Mummy won prizes at home and abroad. From then on, ink wash painting and animation became more popular in China. People in the world get to know more about ink wash since then! 根据语篇内容，选择最佳选项。 1．What color are the ink-wash paintings? A．Black and blue. B．Blue and white. C．Black and white. 2．What do ink wash paintings often go with? A．Poems. B．Animals. C．Flowers. 3．Why are ink wash paintings hard to copy? A．Because they take a lot of time to paint. B．Because they are too beautiful to copy. C．Because they are often improvised works. 4．When did the first ink wash animation in China come out? A．About 56 years ago. B．About 66 years ago. C．About 76 years ago. 5．What is the passage mainly about? A．China’s first ink wash animation. B．How to draw ink wash paintings. C．A beautiful Chinese art, ink wash paintings. 【答案】1．C 2．A 3．C 4．B 5．C 【导语】本文介绍了中国传统艺术水墨画的特点、发展，以及中国第一部水墨动画《小蝌蚪找妈妈》的相关内容。 1．细节理解题。根据“As you can see, the paintings are created just in black and white.”可知，水墨画是黑白两色的，故选C。 2．细节理解题。根据“Also, they often go with Chinese poems.”可知，水墨画常与诗歌搭配，故选A。 3．细节理解题。根据“They are often improvised works from beautiful scenery. Therefore, this type of painting is hard to copy.”可知，水墨画难以复制是因为它们通常是即兴创作的作品，故选C。 4．细节理解题。根据“The first ink wash animation in China came out in 1960.”结合当前年份2026年计算，1960年距今约66年，故选B。 5．主旨大意题。全文围绕水墨画这一中国传统艺术展开，介绍了其特点、相关动画等内容，故选C。 Thanks to technology, people are spending less time writing by hand. In everyday life, we often send messages and emails, or type (打字) our diaries instead of writing on paper. If you have a phone, there’s usually no need to look for a pen. Still, handwriting hasn’t disappeared. Little kids like to draw, and students use pens and pencils at school. Even when teachers teach the same way, everyone’s handwriting turns out distinct—it’s different for each person. But now, many people simply like typing more than writing. Some even feel they’ve forgotten how to write nicely when they pick up a pen. So, is typing better than writing? Some say yes, but others believe handwriting is still very important. Here are some points for each side. Typing is faster and easier. Whether you are messaging a friend or doing schoolwork, typing is quicker. If you make a mistake, you can fix it easily. Typing also has helpful tools, like spellcheck. Working together on a project is often simpler when everyone is typing. Typed words look tidy and are easy for everyone to read. You can send your writing quickly or print many copies. It’s much faster than writing by hand, and your hands don’t get as tired. However, handwriting is a special skill. Each person’s writing is their own—it shows who they are. It is a small, personal art that everyone can create. Studies show that handwriting helps you remember things better because it makes you slow down and think more clearly. A handwritten message feels more personal. Getting a card or letter written by hand makes you feel special. It connects your feelings and thoughts to your words in a way typing sometimes cannot. Writing can also be a nice hobby, like writing to a pen pal or trying calligraphy (书法) . 根据语篇内容，选择最佳选项。 1．Why do people write by hand less now? A．Because they use technology instead. B．Because writing makes their hands tired. C．Because their handwriting is not nice enough. 2．What does the underlined word “distinct” in Paragraph 2 probably mean? A．clear. B．special. C．beautiful. 3．What is simpler when everyone is typing? A．Reading a long book. B．Learning a new language. C．Working together on a project. 4．How does handwriting help people remember things better? A．It makes people slow down and think clearly. B．It lets people spell words correctly. C．It is more fun than typing. 5．What is the writer’s view on typing and handwriting? A．The writer believes handwriting is better. B．The writer believes typing is better. C．The writer gives both opinions. 【答案】1．A 2．B 3．C 4．A 5．C 【导语】本文主要介绍了在科技发达的今天，人们书写变少的原因，以及打字和手写各自的优点。 1．细节理解题。根据文章第1段“Thanks to technology, people are spending less time writing by hand. In everyday life, we often send messages and emails, or type our diaries instead of writing on paper.”可知，人们现在手写变少是因为用科技手段代替了手写。故选A。 2．词句猜测题。根据文章第2段“everyone’s handwriting turns out distinct—it’s different for each person.”可知，破折号后是对该词的解释，意为“每个人的笔迹都不同”；因此，划线单词“distinct”的意思是“特别的、独特的”。故选B。 3．细节理解题。根据文章第4段“Working together on a project is often simpler when everyone is typing.”可知，当所有人都打字时，合作完成一个项目会更简单。故选C。 4．细节理解题。根据文章第5段“Studies show that handwriting helps you remember things better because it makes you slow down and think more clearly.”可知，手写能帮助人们更好地记忆是因为它能让人慢下来、思考更清晰。故选A。 5．观点态度题。通读全文，特别是从第3段“So, is typing better than writing? Some say yes, but others believe handwriting is still very important.”以及第4、5段分别列出打字和手写的优点可以看出，作者是在客观地呈现双方的观点，并没有明显偏向某一方。故选C。 A humanoid (人形机器人) robot named “Xiao An” recently appeared in a classroom at a primary school in Hefei, Anhui Province. This special class showed how artificial intelligence (AI) can be used in real education. Xiao An is 1.4 meters tall and was developed by a local technology company. During the science lesson, the robot worked together with the teacher to help students explore the topic of sound. The robot acted like a professional (专业的) teacher. It guided students step by step and encouraged them to think more deeply. What made Xiao An special was its ability to understand students’ emotions and move naturally when speaking. When the robot entered the classroom, the children were immediately interested. For example, before class began, Xiao An imitated the sounds of different musical instruments. This made the students curious. They started guessing the names and characters of the instruments, which made them creative. The robot was smart enough to answer students’ questions thoughtfully. Instead of just giving simple answers, it helped them learn by encouraging them to find answers themselves. A manager from the company that created Xiao An said that this is the first humanoid robot in the world used in this way in a classroom. The lesson was its first public test with real teachers and students. In the future, the company plans to add more functions (功能).

This made the students curious. They started guessing the names and characters of the instruments”可知，例如，在上课前，小安“imitated”不同乐器的声音，这让学生们感到好奇，他们开始猜测乐器的名称和特征，结合语境，“imitated”意为“模仿”，与“Copied”意思相近，故选A。 4．细节理解题。根据文中“They are also considering using such robots in other subjects.”可知，他们也在考虑将这类机器人用于其他学科，故选C。 5．观点态度题。根据文中“Instead of just giving simple answers, it helped them learn by encouraging them to find answers themselves.”可知，它没有只给出简单答案，而是通过鼓励学生自己寻找答案来帮助他们学习，体现出作者认为人工智能技术在小学的应用是有帮助的，故选A。 With the development of science and technology, robots are becoming increasingly common in our daily lives. One example is the robot barista (咖啡师). It can prepare up to 300 cups of latte (拿铁) art coffee a day, which is equal to what a human can make in 15 hours. What’s more, it doesn’t need to rest and can keep the same high quality for every cup. Does this mean that robots will take the place of humans? “Robots support human workers by doing boring and tiring tasks, freeing them up for more valuable and creative work. Some tasks are too hazardous for humans. Robots can help improve work safety,” said Tian Hua, a senior manager of Aubo. Aubo is a robot company that develops collaborative robots (协作机器人) (cobots). Now, many factories don’t have enough workers. Aubo’s cobots, designed for easy use and priced within reach, are helping to solve this problem. They are efficient (高效的) and can do the work of three to four human workers in the same period of time. Aubo also devotes itself to helping workers learn new skills. It has offered over 1,000 training programs, through which thousands of workers have become skilled cobot operators (操作人员). “At first, I thought the use of robots would take my job away,” said Liu Wei, who used to be an assembly worker and is now an operator. “Instead, it gave me a better one with more pay and more control.” Cobots are not job-takers, but partners. They open up new possibilities for our daily lives, factories and workers. In the future, we may see even smarter cobots, which will be able to complete more difficult tasks and work more closely with humans. 根据语篇内容，选择最佳选项。 1．What can we learn about the robot barista? A．It is the only robot used in our daily lives. B．It needs 15 hours to make 300 cups of coffee. C．It can work without taking a break while making coffee. 2．What does the underlined word “hazardous” most probably mean? A．Impossible. B．Boring. C．Dangerous. 3．Why are cobots helpful to many factories? ① They are easy to use and not expensive. ② They are more efficient than human workers. ③ They can completely take the place of human workers. A．①② B．②③ C．①③ 4．How did Liu Wei probably feel about the use of robots at first? A．Thankful. B．Worried. C．Hopeful. 5．What can we learn from the last paragraph? A．Future cobots will become smarter. B．China’s cobot technology will lead the world. C．With the help of cobots, humans no longer need to work. 【答案】1．C 2．C 3．A 4．B 5．A 【导语】本文是一篇说明文，主要介绍了科技发展下机器人在生活和工厂中的应用，以咖啡师机器人、Aubo协作机器人为例，说明机器人并非取代人类，而是作为合作伙伴助力工作，还能帮助工人习得新技能，未来协作机器人会更智能。 1．细节理解题。根据文章第1段“What’s more, it doesn’t need to rest and can keep the same high quality for every cup.”可知，机器人咖啡师制作咖啡时无需休息，且能保证每杯咖啡品质一致。故选C。 2．词句猜测题。根据文章第2段“Robots can help improve work safety”可知，机器人能提升工作安全性，说明这类任务对人类而言是不安全的，可推测hazardous意为“危险的”。故选C。 3．细节理解题。根据文章第3段“Aubo’s cobots, designed for easy use and priced within reach, are helping to solve this problem. They are efficient and can do the work of three to four human workers in the same period of time.”可知，协作机器人易用且价格亲民，同时工作效率比人类高；文章全程说明机器人不会取代人类，故③错误。故选A。 4．观点态度题。根据文章第4段“At first, I thought the use of robots would take my job away”可知，刘伟起初认为机器人会夺走自己的工作，由此可判断他最初是担忧的。故选B。 5．细节理解题。根据文章最后1段“In the future, we may see even smarter cobots, which will be able to complete more difficult tasks and work more closely with humans.”可知，未来的协作机器人会变得更加智能，能完成更难的任务。故选A。 Many people complain about their bad memory, especially when they are older. How can we improve our memory? Many people think that repeating things is the best way to remember them. While this surely helps short-term memory (remembering a telephone number for a few seconds, for example), psychologists (心理学家) doubt whether it can help you remember things for very long. The British psychologist E. C． Stanford seemed to prove this point when he tested himself on five prayers (祈祷文) that he had read aloud every morning for over 25 years. He found that he could remember no more than three words of some of them! More helpful, especially for remembering numbers, is grouping the information. The following numbers would be impossible for most of us to remember: 1492178919931848. But look at them in chunks, and it becomes much easier: 1492 1789 1993 1848. According to experts, there are many ways of training your memory. Many of them involve forming a mental picture of the things to be memorized. One method, which may be useful in learning foreign languages, is to create a picture in your mind connected to a word you want to remember. Another method is to invent a story that includes all the things you want to remember. In experiments, people were asked to remember up to 120 words using this skill; when tested afterwards, they were able to remember 90% of them! However, not all of us are interested in learning long lists of names and numbers just for fun. For those studying a large amount of information, psychologists suggest that the best way to form meaningful connections is to ask yourself lots of questions as you go along. So, for example, if you were reading about a kind of disease, you would ask yourself questions like: “Do people get it from water?”, “What parts of the body does it influence?” and so on. This is said to be far more useful than time spent reading and re-reading notes. 根据语篇内容，选择最佳答案。 1．Which of the following did E. C． Stanford seem to agree with? A．Repeating things doesn’t help short-term memory. B．Repeating things doesn’t help remember telephone numbers. C．Repeating things doesn’t help remember things for a long time. 2．What does the underlined phrase “in chunks” probably mean in Chinese? A．细心地 B．反复地 C．成块地 3．What are Paragraph 3 and Paragraph 4 mainly about? A．The methods of training memory. B．The advantages of having good memory. C．The reasons for learning foreign languages. 4．According to psychologists, what’s the best way to study a large amount of information? A．Create a picture in your mind. B．Ask yourself lots of questions about it. C．Spend lots of time reading and rereading notes. 5．What’s the main purpose of the text? A．To complain about his bad memory. B．To share some ways of improving memory. C．To explain some interesting memory experiments. 【答案】1．C 2．C 3．A 4．B 5．B 【导语】本文主要介绍了改善记忆力的方法。 1．细节理解题。根据“psychologists doubt whether it can help you remember things for very long”以及E. C. Stanford的测试结果“He found that he could remember no more than three words of some of them”可知，重复并不能帮助长期记忆。故选C。 2．词句猜测题。根据“The following numbers would be impossible for most of us to remember: 1492178919931848. But look at them in chunks, and it becomes much easier: 1492 1789 1993 1848.”可知，原文用数字举例，将长串数字 1492178919931848拆分为1492 1789 1993 1848，说明“in chunks”是“成块地”的意思。故选C。 3．主旨大意题。根据第三段中的“there are many ways of training your memory”和第四段中的“Another method...”可知，这两段主要讲训练记忆的方法。故选A。 4．细节理解题。根据“For those studying a large amount of information, psychologists suggest that the best way to form meaningful connections is to ask yourself lots of questions as you go along.”可知，学习大量信息的最佳方式是“问自己很多相关问题”。故选B。 5．推理判断题。根据文章内容可知，文章开头提出“如何改善记忆力”的问题，随后介绍了多种记忆训练方法，因此全文的主要目的是分享一些改善记忆力的方法。故选B。 If you feel stressed at school, what can you do to make yourself happier? Some may eat their favorite food or listen to some music. Others may go for a walk or get some exercise. A new study found another great way to lower students’ stress—playing with dogs. Scientists studied 105 students between the ages of eight and nine. The children were divided into 3 groups. The students in the first group spent 20 minutes with a dog and its trainer. They watched the trained dogs perform and even played with them. They did this twice a week for 4 weeks. The second group spent the same amount of time doing exercise to relax. The last group did neither of these things. During this time, the scientists recorded the students’ cortisol levels (皮质醇水平). Cortisol is a stress hormone (激素). The more stressed you feel, the more cortisol you will have in your body. What did the scientists find? Both the second and third groups showed rises in cortisol levels. The first group, however, showed no big increase. And the children in this group had the lowest cortisol levels right after playing with the dogs. According to the study, students enjoy playing with dogs, and it helps them become happier. The stress hormone falls over time this way, which is good for students’ health. But here comes the next question: Is 20 minutes of playtime with a dog the best amount of time? Scientists are going to keep working to find out the answer. 1．How does the writer start the passage? A．By asking a question. B．By telling a story. C．By listing numbers. 2．What made the testing results of the three groups different? A．The time. B．The ages. C．The activities. 3．Which one shows the relationship between students’ stress (x) and cortisol levels (y)? A． B． C． 4．What does the underlined word “them” refer to? A．Trainers. B．Dogs. C．Students. 5．What may the scientists study next? A．More useful ways to lower stress. B．New skills of keeping pets at home. C．The best amount of time to play with a dog. 【答案】1．A 2．C 3．A 4．C 5．C 【导语】本文通过一项科学研究，探讨了与狗互动是否能有效降低8至9岁学生的压力水平，并对比了其他活动方式的效果，同时展望了未来的研究方向。 1．细节理解题。根据文章第一段“If you feel stressed at school, what can you do to make yourself happier?”可知，作者是通过提出一个问题来引出文章主题的。故选A。 2．细节理解题。根据文章第二段“The students in the first group spent 20 minutes with a dog and its trainer... The second group spent the same amount of time doing exercise to relax. The last group did neither of these things.”可知，第一组与狗互动，第二组运动，第三组无特殊活动。验证结果的关键在所进行的活动不同。故选C。 3．推理判断题。根据文章第三段“Cortisol is a stress hormone.

Common ways of cleaning sea rubbish have high costs, and they may hurt fish. These problems can be successfully solved by a sea rubbish cleaning robot called Sea Sweeper 1000. It looks like a lantern fish from the outside. ② The robot fish was invented by a little inventor named Lainey and an artist named Lottie Smith. Inside, it has two “stomachs”. They are used to store, recycle and burn rubbish. ③ The left stomach will be used to burn down rubbish and create energy for the robot to keep running. And the things left after burning will be divided into small parts, and then placed into the bags on the robot’s back. The right stomach can store rubbish that can be recycled. When it gets full, rubbish will be placed in the bag in the robot’s tail. Once the bag is full, the robot will come back. ④ The lantern above the robot’s head has a sensor (传感器) and a camera. The sensor helps avoid taking in fish. But if the robot does take in small fish, don’t worry. The space between its teeth is big enough for them to swim out. And the camera can send back photos to its user when there is rubbish. Then the user can know if the rubbish should be recycled or burned. ⑤ Although there are still some parts that need to be improved, with the robot’s help, we can protect the sea environment and create a better future for human beings. 根据语篇内容，选择最佳选项。 1．What does Sea Sweeper 1000 look like?

In a new study, scientists have found the answer. That is, the cold air breaks the immune response (免疫反应) in our noses. The nose is an important part of our body’s immune system. When a virus (病毒) goes into the nose, the cells (细胞) in the nose will create billions of simple copies of themselves called EVs—extracellular vesicles (细胞外囊泡). “EVs can’t divide like cells, but they are like little cells that can kill the viruses,” said Benjamin Bleier, the researcher of the study from Harvard Medical School. “They are like little arms that catch the viruses when you breathe them in.” Then, the viruses on EVs will be expelled from our body as snot (鼻涕). However, when cold weather hits, the nose’s “superpower” becomes less powerful. The study found that when the temperature in the nose drops by 5℃, nearly 50% of EVs will be useless. Cold air makes people catch viruses more easily because “you’ve lost some of your immunity (免疫力)”, said Bleier. This is why we should wear masks (口罩) in winter. “Wearing masks can not only protect us from viruses, but it’s also like wearing a sweater on our nose,” Bleier said. The warmer you keep your nose, the better it works to fight against viruses. In the future, Bleier expects to develop some nose medicine based on this new finding. “Scientists might find a way to make the nose think it meets a virus, so the nose can improve its ability to fight against viruses,” Bleier said. 根据语篇内容，选择最佳选项。 1．What will happen when a virus goes into the nose? A．EVs will divide into millions of little cells. B．The body’s immune system will be broken. C．The cells in the nose will create billions of EVs. 2．What does the underlined word “expelled” probably mean? A．排出 B．引进 C．修补 3．Why do people catch viruses more easily in cold weather? A．Because there is more snot in our noses. B．Because nearly 50% of EVs will be useless. C．Because our noses will be more powerful. 4．How can we better fight against viruses in winter? A．By taking medicine. B．By wearing masks. C．By wearing a sweater. 5．What is the main idea of the passage? A．How the cells in the nose create EVs when a virus goes into the nose. B．How scientists develop new nose medicine to help us stay healthy. C．Why people get more colds in cold weather and how to protect ourselves. 【答案】1．C 2．A 3．B 4．B 5．C 【导语】本文主要讲述了科学家研究发现冬天人们更容易患感冒和流感的原因，即冷空气会破坏我们鼻子里的免疫反应，还介绍了鼻子免疫系统的工作原理、冷空气对免疫系统的影响以及在冬天保护自己免受病毒感染的方法等内容。 1．细节理解题。根据“When a virus (病毒) goes into the nose, the cells (细胞) in the nose will create billions of simple copies of themselves called EVs—extracellular vesicles (细胞外囊泡).”可知，当病毒进入鼻子时，鼻子里的细胞会产生数十亿个细胞外囊泡。故选C。 2．词句猜测题。根据“‘They are like little arms that catch the viruses when you breathe them in.’ Then, the viruses on EVs will be expelled from our body as snot (鼻涕).”可知，细胞外囊泡像小手臂一样，在你吸入病毒时抓住病毒，然后病毒会随着鼻涕从身体里排出，所以“expelled”意思是“排出”。故选A。 3．细节理解题。根据“The study found that when the temperature in the nose drops by 5℃, nearly 50% of EVs will be useless. Cold air makes people catch viruses more easily because ‘you’ve lost some of your immunity (免疫力)’, said Bleier.”可知，冷空气使鼻子里的温度下降，近50%的细胞外囊泡会失效，人们失去了一些免疫力，所以更容易感染病毒。故选B。 4．细节理解题。根据“This is why we should wear masks (口罩) in winter. ‘Wearing masks can not only protect us from viruses, but it’s also like wearing a sweater on our nose,’ Bleier said. The warmer you keep your nose, the better it works to fight against viruses.”可知，冬天戴口罩能让我们的鼻子保持温暖，更好地对抗病毒。故选B。 5．主旨大意题。根据“Why do people get more colds and flu when it’s cold outside? In a new study, scientists have found the answer.”以及全文内容可知，文章主要讲述了为什么人们在寒冷的天气更容易患感冒和流感以及如何在冬天保护自己免受病毒感染。故选C。 China, with Four Great Inventions, in ancient times, has once again showed its ability to change the world with its “new four great inventions”: high-speed railways, electronic payments, shared bicycles and online shopping, which have made the daily life of the public more and more convenient. The four innovative ways of life are most popular among young people, according to a survey by the Belt and Road-Research Institute (一带一路研究院) of Beijing Foreign Studies University. “The ‘new four great inventions’ are all related (相关的) to China’s high-tech (高科技), which made the lives of people easier in China,” said Wu Hao, the director of Beijing Foreign Studies University. “My wallet is no longer in use. I can buy and eat whatever I want simply with my phone,” said Lin Jinlong, a foreign student from Cambodia (柬埔寨), adding that “Even pancake sellers are using Alipay (mobile payment). We can also order food at home, which is super convenient. If I were at home in Cambodia, I would have to go outdoors.” As a big fan of bicycles, he also showed his love for China’s shared bicycles. Saying that “shared bikes (共享单车) are bringing cycling back to people’s lives and they are making public transport more convenient and less crowded, and encouraging people to be more active.” Rebecca Fannin, the founder of Silicon Dragon (硅谷龙), noted that China is beginning to lead in innovation in some ways. “It is increasingly (越来越多地) clear that China is inventing and no longer copying western ideas.

But sometimes it does not seem like the same language. In fact, there are some important differences between British English and American English.     First of all, they sound very different. Often, Americans don’t say each word separately. They say several words together. Americans may say “I dunno” instead of “I don’t know”. Or they may say “Whaddya say?” instead of “What did you say?” However, the British are more careful in their speech. They usually say all the words and keep them separate.     Sound is not the only difference between British English and American English. People in these two countries sometimes use different words to refer to the same thing. For example, the vocabulary for cars and driving is very different. Americans drive trucks, but in England people drive lorries.     Many expressions are also different in the two countries. In England, if you are going to telephone your friends, you “phone them up”. In America, you “give them a call”.     There are also some differences in grammar. For example, Americans usually use the helping verb “do” when they ask a question. They say “Do you have a storybook?” But the British often leave out the helping verb. They say “Have you a storybook?”     Most languages are like this. Languages change over time. When people live in separate places, the languages change in different ways. This is what has happened to English. It can also happen to other languages, such as French. Many people in Canada speak French but their French is very different from the French of France. 根据语篇内容，选择最佳选项。 1．What difference between British English and American English is mentioned in Paragraph 2?

They turned CO₂ into starch (淀粉). ③Starch is the main part of rice and corn that we eat every day. Usually it’s created by plants with CO₂, water and sunlight. According to the team’s director Ma Yanhe, it usually takes the plants nearly sixty steps to produce starch. But now, the team, after six years of hard work, has found a simpler way to do this, with only eleven steps. ④“Our study shows that creating something like starch is possible in a laboratory, and this technology may be helpful in many areas,” said Ma. ⑤This method makes it possible to produce food in factories instead of traditional farming. This will not only help make plenty of food, but also save water and land. It may also help recycle CO₂ to deal with climate change, according to China Daily. ⑥The study can be helpful in space, too. Astronauts may no longer need to worry about their food as they travel in space.

Scientific research shows that they are born with certain unusual abilities for direction. ②A certain kind of ant, for example, can count their steps to avoid getting lost. They can go as far as 110 metres and bring food home. These ants live in the open desert, so they have nothing to guide them along the way. It’s like someone walking six kilometres through a dark forest. ③Some fish have an unbelievable sense of smell. They can smell even a single drop of their home water in a large sea area. Some sea birds have a similar ability. They are able to make a smell map of their flying area. ④Some animals can sense the earth’s magnetic field (磁场), while humans can’t. This magnetic field guides a certain kind of fish when they swim a long way to a place and then back. How can this kind of fish do that? It is still a mystery. Scientists have no good answers yet. ⑤However, animals with such unusual abilities still have difficulty dealing with environmental changes caused by human activities. For example, many birds depend on stars for direction, but they get lost easily at night when city lights are kept on all night. To solve this problem, we can simply turn off some lights at night.

Now scientists are looking into a bee’s brain. Clint Perry, a scientist, has spent much time studying how bees think. He says studying bees is not very different from studying other animals. “The main difficulty is to design (设计) an experiment (实验) bee and get what we want,” he says. “With humans, we can ask them a question and get an answer. But we can’t use the same way to get an answer from bees. They are just trying to get sugar. Bees like sugar.” The fact that bees like sugar is helpful for scientists to design experiments. For example, in one experiment, Perry gave bees a task: to find delicious sugar on a landing place above a black bar (棒). Perry made the task easier or harder by moving the landing place farther from or closer to the black bar. He found that bees would avoid the task when it was difficult. And when the task was easy, bees would try it. As for humans, we might choose not to take a test when we weren’t ready for it. And we might choose to take the test when we were well prepared. In the same way, bees seemed to make decisions like humans. Perry points out that we are not sure whether bees actually make a thoughtful choice from experiments. Now scientists still do not know how bees manage to do so much with their tiny brains. But learning more about how bees’ brains work could help us learn more about how our own brains deal with information. 根据语篇内容，选择最佳选项。 1．What did Perry study in his experiments? A．How bees sleep. B．How bees think. C．How bees dream. 2．What can we know from Paragraph 2? A．Bees can talk. B．Bees are lazy. C．Bees like sugar. 3．What would bees do when the task was easy according to Paragraph 3? A．They would try it. B．They would avoid it. C．They would praise it. 4．What’s the importance of looking into bees’ brains? A．It helps us learn how human brains work. B．It tells us how to make thoughtful choices. C．It lets us know how to deal with information. 5．Where is the article probably taken from? A．A travel magazine. B．A sports magazine. C．A science magazine. Southern white rhinos (犀牛) mainly live in Africa. They are very large in size, about 4 metres long, 1.75 metres high, and over two tons in weight. There are two horns (角) on the nose. The front horn is over half a metre long, while the other one is smaller. Southern white rhinos are not really white. They are grey in colour. “White” may come from the Afrikaans word for “wide”. It has some connection with their wide mouths. Southern white rhinos live on grass, leaves, fruit and so on. They have very poor eyesight. However, they have good hearing and an excellent sense of smell. Their skin (皮肤) is nearly 5 cm thick but is very sensitive. During the day, they try to find a cool place to avoid sunburn. Southern white rhinos lie in mud (泥浆) when they can, as it sticks to their skin and protects them from the bright African sun. Some humans kill rhinos for their horns. They sell horns to those who believe horns have magic powers or can treat sickness. It puts southern white rhinos in danger. Now many actions are taken to protect southern white rhinos. The international trade in rhino horn has been stopped in the world. Besides, many protected areas have been built, especially in South Africa. Up to 2020, more than 20 countries have made rules to protect southern white rhinos. Today the number of southern white rhinos has increased to over 20,000 in the wild. 根据语篇内容，选择最佳选项。 1．Where do southern white rhinos mainly live? A．In Europe. B．In America.

A．Ways to feed southern white rhinos. B．Actions of protecting southern white rhinos. C．Places for southern white rhinos to live in. 【热点话题练习】 Do you know about Traditional Chinese Medicine (TCM)? It’s an old way to keep people healthy in China, with a history of thousands of years. TCM doctors often check your tongue (舌头), give you herbs (草药), or use acupoints (穴位) to treat illnesses. Now, Artificial Intelligence (AI) is helping TCM work better. AI is smart—it can learn and think like humans, and we can see it in computers and robots. Let’s see how AI helps with TCM herbs first. TCM doctors give people bags of different herbs. People need to boil the herbs in water to make a drink, but it’s hard to get the right temperature and time. A small mistake makes the medicine less useful. But AI machines can solve this problem. They read doctors’ prescriptions and boil herbs in their own ways. They control the temperature perfectly, so the medicine is always good. This saves people a lot of time. AI robots also help with moxibustion (艾灸), a special TCM treatment. Doctors use warmth from burning herbs near your skin to reach acupoints. Finding the right acupoints is very important. AI robots have smart eyes—they can find acupoints quickly. The robot’s arm is steady (稳定的) and never shakes, making the treatment safe. AI is not here to replace TCM doctors. Doctors are still the most important. AI is just a “super assistant” that helps doctors work faster and better, making TCM treatments more efficient for everyone. 根据语篇内容，选择最佳选项。 1．What is TCM according to the passage? A．A new way to make robots smart. B．An old Chinese way to stay healthy. C．A kind of AI machine for treatment. 2．Why is making a TCM herb drink difficult for people? A．Because it takes all day to boil the herbs. B．Because people can’t find enough different herbs. C．Because it’s difficult to get the right temperature and time. 3．What does the underlined word “prescriptions” mean? A．Instructions. B．Tools. C．Records. 4．What helps robots find acupoints quickly from Paragraph 4? A．Their feet. B．Their arms. C．Their smart eyes. 5．What is the main idea of the passage? A．AI machines can boil herbs very quickly. B．AI helps TCM work more efficiently and safely. C．TCM is an old and useful way to keep healthy. Ink wash painting (水墨画) is an old and beautiful Chinese art. This special drawing technique (技巧) is created with a brush, dipped into ink, then into water. As you can see, the paintings are created just in black and white. It is said that the technique was invented by an artist named Wang Wei. Ink wash paintings often feature trees, flowers, landscapes, animals, birds and people. Also, they often go with Chinese poems. The painting style does not put high importance on a precise (精确的) description of a real scene or object. They are often improvised (即兴的) works from beautiful scenery. Therefore, this type of painting is hard to copy. Today, there are many new Chinese artists who use the traditional Chinese ink wash technique to draw new scenery and pictures. The first ink wash animation (动画) in China came out in 1960. It’s called Little Tadpole Looking for Mummy. All the animals, plants and rocks in the film are drawn with ink and brush. The film is about 15 minutes long. But it took lots of work. Without computers, the artists had to draw everything by hand. One second of animation needs 24 pictures!

Thanks to technology, people are spending less time writing by hand. In everyday life, we often send messages and emails, or type (打字) our diaries instead of writing on paper. If you have a phone, there’s usually no need to look for a pen. Still, handwriting hasn’t disappeared. Little kids like to draw, and students use pens and pencils at school. Even when teachers teach the same way, everyone’s handwriting turns out distinct—it’s different for each person. But now, many people simply like typing more than writing. Some even feel they’ve forgotten how to write nicely when they pick up a pen. So, is typing better than writing? Some say yes, but others believe handwriting is still very important. Here are some points for each side. Typing is faster and easier. Whether you are messaging a friend or doing schoolwork, typing is quicker. If you make a mistake, you can fix it easily. Typing also has helpful tools, like spellcheck. Working together on a project is often simpler when everyone is typing. Typed words look tidy and are easy for everyone to read. You can send your writing quickly or print many copies. It’s much faster than writing by hand, and your hands don’t get as tired. However, handwriting is a special skill. Each person’s writing is their own—it shows who they are. It is a small, personal art that everyone can create. Studies show that handwriting helps you remember things better because it makes you slow down and think more clearly. A handwritten message feels more personal. Getting a card or letter written by hand makes you feel special. It connects your feelings and thoughts to your words in a way typing sometimes cannot. Writing can also be a nice hobby, like writing to a pen pal or trying calligraphy (书法) . 根据语篇内容，选择最佳选项。 1．Why do people write by hand less now? A．Because they use technology instead. B．Because writing makes their hands tired. C．Because their handwriting is not nice enough. 2．What does the underlined word “distinct” in Paragraph 2 probably mean? A．clear. B．special. C．beautiful. 3．What is simpler when everyone is typing? A．Reading a long book. B．Learning a new language. C．Working together on a project. 4．How does handwriting help people remember things better? A．It makes people slow down and think clearly. B．It lets people spell words correctly. C．It is more fun than typing. 5．What is the writer’s view on typing and handwriting? A．The writer believes handwriting is better. B．The writer believes typing is better. C．The writer gives both opinions. A humanoid (人形机器人) robot named “Xiao An” recently appeared in a classroom at a primary school in Hefei, Anhui Province. This special class showed how artificial intelligence (AI) can be used in real education. Xiao An is 1.4 meters tall and was developed by a local technology company. During the science lesson, the robot worked together with the teacher to help students explore the topic of sound. The robot acted like a professional (专业的) teacher. It guided students step by step and encouraged them to think more deeply. What made Xiao An special was its ability to understand students’ emotions and move naturally when speaking. When the robot entered the classroom, the children were immediately interested. For example, before class began, Xiao An imitated the sounds of different musical instruments. This made the students curious. They started guessing the names and characters of the instruments, which made them creative. The robot was smart enough to answer students’ questions thoughtfully. Instead of just giving simple answers, it helped them learn by encouraging them to find answers themselves. A manager from the company that created Xiao An said that this is the first humanoid robot in the world used in this way in a classroom. The lesson was its first public test with real teachers and students. In the future, the company plans to add more functions (功能). They are also considering using such robots in other subjects. 根据语篇内容，选择最佳选项。 1．What class did the robot “Xiao An” appear in recently? A．IT. B．Science. C．Music. 2．What is special about Xiao An compared to other robots? A．It can play real musical instruments. B．It can teach students without any human teacher. C．It can understand students’ emotions and move naturally. 3．What does the underlined word “imitated” in Paragraph 3 probably mean? A．Copied. B．Recorded. C．Remembered. 4．What will the company probably do next? A．Make more robots. B．Stop using robots in school. C．Use such robots in other subjects. 5．What does the writer think of using AI technology at primary school? A．Helpful. B．Useless. C．Uncertain. With the development of science and technology, robots are becoming increasingly common in our daily lives. One example is the robot barista (咖啡师). It can prepare up to 300 cups of latte (拿铁) art coffee a day, which is equal to what a human can make in 15 hours. What’s more, it doesn’t need to rest and can keep the same high quality for every cup. Does this mean that robots will take the place of humans? “Robots support human workers by doing boring and tiring tasks, freeing them up for more valuable and creative work. Some tasks are too hazardous for humans. Robots can help improve work safety,” said Tian Hua, a senior manager of Aubo. Aubo is a robot company that develops collaborative robots (协作机器人) (cobots). Now, many factories don’t have enough workers. Aubo’s cobots, designed for easy use and priced within reach, are helping to solve this problem. They are efficient (高效的) and can do the work of three to four human workers in the same period of time. Aubo also devotes itself to helping workers learn new skills. It has offered over 1,000 training programs, through which thousands of workers have become skilled cobot operators (操作人员). “At first, I thought the use of robots would take my job away,” said Liu Wei, who used to be an assembly worker and is now an operator. “Instead, it gave me a better one with more pay and more control.” Cobots are not job-takers, but partners. They open up new possibilities for our daily lives, factories and workers. In the future, we may see even smarter cobots, which will be able to complete more difficult tasks and work more closely with humans. 根据语篇内容，选择最佳选项。 1．What can we learn about the robot barista? A．It is the only robot used in our daily lives. B．It needs 15 hours to make 300 cups of coffee.

B．China’s cobot technology will lead the world. C．With the help of cobots, humans no longer need to work. Many people complain about their bad memory, especially when they are older. How can we improve our memory? Many people think that repeating things is the best way to remember them. While this surely helps short-term memory (remembering a telephone number for a few seconds, for example), psychologists (心理学家) doubt whether it can help you remember things for very long. The British psychologist E. C． Stanford seemed to prove this point when he tested himself on five prayers (祈祷文) that he had read aloud every morning for over 25 years. He found that he could remember no more than three words of some of them! More helpful, especially for remembering numbers, is grouping the information. The following numbers would be impossible for most of us to remember: 1492178919931848. But look at them in chunks, and it becomes much easier: 1492 1789 1993 1848. According to experts, there are many ways of training your memory. Many of them involve forming a mental picture of the things to be memorized. One method, which may be useful in learning foreign languages, is to create a picture in your mind connected to a word you want to remember. Another method is to invent a story that includes all the things you want to remember. In experiments, people were asked to remember up to 120 words using this skill; when tested afterwards, they were able to remember 90% of them! However, not all of us are interested in learning long lists of names and numbers just for fun. For those studying a large amount of information, psychologists suggest that the best way to form meaningful connections is to ask yourself lots of questions as you go along. So, for example, if you were reading about a kind of disease, you would ask yourself questions like: “Do people get it from water?”, “What parts of the body does it influence?” and so on. This is said to be far more useful than time spent reading and re-reading notes. 根据语篇内容，选择最佳答案。 1．Which of the following did E. C． Stanford seem to agree with?

Some may eat their favorite food or listen to some music. Others may go for a walk or get some exercise. A new study found another great way to lower students’ stress—playing with dogs. Scientists studied 105 students between the ages of eight and nine. The children were divided into 3 groups. The students in the first group spent 20 minutes with a dog and its trainer. They watched the trained dogs perform and even played with them. They did this twice a week for 4 weeks. The second group spent the same amount of time doing exercise to relax. The last group did neither of these things. During this time, the scientists recorded the students’ cortisol levels (皮质醇水平). Cortisol is a stress hormone (激素). The more stressed you feel, the more cortisol you will have in your body. What did the scientists find? Both the second and third groups showed rises in cortisol levels. The first group, however, showed no big increase. And the children in this group had the lowest cortisol levels right after playing with the dogs. According to the study, students enjoy playing with dogs, and it helps them become happier. The stress hormone falls over time this way, which is good for students’ health. But here comes the next question: Is 20 minutes of playtime with a dog the best amount of time? Scientists are going to keep working to find out the answer. 1．How does the writer start the passage? A．By asking a question. B．By telling a story. C．By listing numbers. 2．What made the testing results of the three groups different? A．The time. B．The ages. C．The activities. 3．Which one shows the relationship between students’ stress (x) and cortisol levels (y)? A． B． C． 4．What does the underlined word “them” refer to? A．Trainers. B．Dogs. C．Students. 5．What may the scientists study next? A．More useful ways to lower stress. B．New skills of keeping pets at home. C．The best amount of time to play with a dog. ① Nowadays, there is more and more rubbish in the sea. And the sea environment is seriously polluted. Common ways of cleaning sea rubbish have high costs, and they may hurt fish. These problems can be successfully solved by a sea rubbish cleaning robot called Sea Sweeper 1000. It looks like a lantern fish from the outside. ② The robot fish was invented by a little inventor named Lainey and an artist named Lottie Smith. Inside, it has two “stomachs”. They are used to store, recycle and burn rubbish. ③ The left stomach will be used to burn down rubbish and create energy for the robot to keep running. And the things left after burning will be divided into small parts, and then placed into the bags on the robot’s back. The right stomach can store rubbish that can be recycled. When it gets full, rubbish will be placed in the bag in the robot’s tail. Once the bag is full, the robot will come back. ④ The lantern above the robot’s head has a sensor (传感器) and a camera. The sensor helps avoid taking in fish. But if the robot does take in small fish, don’t worry. The space between its teeth is big enough for them to swim out. And the camera can send back photos to its user when there is rubbish. Then the user can know if the rubbish should be recycled or burned. ⑤ Although there are still some parts that need to be improved, with the robot’s help, we can protect the sea environment and create a better future for human beings. 根据语篇内容，选择最佳选项。 1．What does Sea Sweeper 1000 look like?

C．The photos. 3．In which part will the rubbish be placed when the right stomach gets full? A．The bag on the robot’s back. B．The bag in the robot’s tail. C．The left stomach. 4．What’s Paragraph 4 mainly about? A．How the sensor and the camera work. B．Where the small fish and the robot swim. C．Why the user recycles or burns the rubbish. 5．What’s the purpose of the text? A．To teach us how to invent robots. B．To advise people to buy a new kind of robot. C．To show how a robot protects the environment. Why do people get more colds and flu when it’s cold outside? In a new study, scientists have found the answer. That is, the cold air breaks the immune response (免疫反应) in our noses. The nose is an important part of our body’s immune system. When a virus (病毒) goes into the nose, the cells (细胞) in the nose will create billions of simple copies of themselves called EVs—extracellular vesicles (细胞外囊泡). “EVs can’t divide like cells, but they are like little cells that can kill the viruses,” said Benjamin Bleier, the researcher of the study from Harvard Medical School. “They are like little arms that catch the viruses when you breathe them in.” Then, the viruses on EVs will be expelled from our body as snot (鼻涕). However, when cold weather hits, the nose’s “superpower” becomes less powerful. The study found that when the temperature in the nose drops by 5℃, nearly 50% of EVs will be useless. Cold air makes people catch viruses more easily because “you’ve lost some of your immunity (免疫力)”, said Bleier. This is why we should wear masks (口罩) in winter. “Wearing masks can not only protect us from viruses, but it’s also like wearing a sweater on our nose,” Bleier said. The warmer you keep your nose, the better it works to fight against viruses. In the future, Bleier expects to develop some nose medicine based on this new finding. “Scientists might find a way to make the nose think it meets a virus, so the nose can improve its ability to fight against viruses,” Bleier said. 根据语篇内容，选择最佳选项。 1．What will happen when a virus goes into the nose? A．EVs will divide into millions of little cells. B．The body’s immune system will be broken. C．The cells in the nose will create billions of EVs. 2．What does the underlined word “expelled” probably mean? A．排出 B．引进 C．修补 3．Why do people catch viruses more easily in cold weather?

A．By taking medicine. B．By wearing masks. C．By wearing a sweater. 5．What is the main idea of the passage? A．How the cells in the nose create EVs when a virus goes into the nose. B．How scientists develop new nose medicine to help us stay healthy. C．Why people get more colds in cold weather and how to protect ourselves. China, with Four Great Inventions, in ancient times, has once again showed its ability to change the world with its “new four great inventions”: high-speed railways, electronic payments, shared bicycles and online shopping, which have made the daily life of the public more and more convenient. The four innovative ways of life are most popular among young people, according to a survey by the Belt and Road-Research Institute (一带一路研究院) of Beijing Foreign Studies University. “The ‘new four great inventions’ are all related (相关的) to China’s high-tech (高科技), which made the lives of people easier in China,” said Wu Hao, the director of Beijing Foreign Studies University. “My wallet is no longer in use. I can buy and eat whatever I want simply with my phone,” said Lin Jinlong, a foreign student from Cambodia (柬埔寨), adding that “Even pancake sellers are using Alipay (mobile payment). We can also order food at home, which is super convenient. If I were at home in Cambodia, I would have to go outdoors.” As a big fan of bicycles, he also showed his love for China’s shared bicycles. Saying that “shared bikes (共享单车) are bringing cycling back to people’s lives and they are making public transport more convenient and less crowded, and encouraging people to be more active.” Rebecca Fannin, the founder of Silicon Dragon (硅谷龙), noted that China is beginning to lead in innovation in some ways. “It is increasingly (越来越多地) clear that China is inventing and no longer copying western ideas. It is also increasingly clear that China is leading in many ways such as social messaging app WeChat,” she said. 根据语篇内容，选择最佳选项。 1．Which of the following is NOT in “new four great inventions”?

A．China’s Four Great Inventions in ancient times. B．China’s new four great inventions and their influence. C．Foreign student from Cambodia living and studying in China.     American and British people both speak English of course. But sometimes it does not seem like the same language. In fact, there are some important differences between British English and American English.     First of all, they sound very different. Often, Americans don’t say each word separately. They say several words together. Americans may say “I dunno” instead of “I don’t know”. Or they may say “Whaddya say?” instead of “What did you say?” However, the British are more careful in their speech. They usually say all the words and keep them separate.     Sound is not the only difference between British English and American English. People in these two countries sometimes use different words to refer to the same thing. For example, the vocabulary for cars and driving is very different. Americans drive trucks, but in England people drive lorries.     Many expressions are also different in the two countries. In England, if you are going to telephone your friends, you “phone them up”. In America, you “give them a call”.     There are also some differences in grammar. For example, Americans usually use the helping verb “do” when they ask a question. They say “Do you have a storybook?” But the British often leave out the helping verb. They say “Have you a storybook?”     Most languages are like this. Languages change over time. When people live in separate places, the languages change in different ways. This is what has happened to English. It can also happen to other languages, such as French. Many people in Canada speak French but their French is very different from the French of France. 根据语篇内容，选择最佳选项。 1．What difference between British English and American English is mentioned in Paragraph 2? A．Sound. B．Spelling. C．Grammar. 2．How does the writer express his idea in Paragraph 3? A．By listing numbers. B．By giving an example. C．By telling a story. 3．Which of the following expressions is British English? A．Do you have a bike? B．I’ll give my cousin a call at once. C．Have you a computer? 4．How many kinds of differences are mentioned in the text? A．Three. B．Four. C．Five. 5．Which of the following is TRUE? A．American English and British English are quite different from each other in some ways. B．People in different places speak the same language in the same way. C．There are two kinds of English in the world. ①It’s often said, “You can’t live only on air.” But now the Chinese scientists can tell you: Maybe you can. ②Recently, some Chinese scientists have made a big breakthrough (突破). They turned CO₂ into starch (淀粉). ③Starch is the main part of rice and corn that we eat every day. Usually it’s created by plants with CO₂, water and sunlight. According to the team’s director Ma Yanhe, it usually takes the plants nearly sixty steps to produce starch. But now, the team, after six years of hard work, has found a simpler way to do this, with only eleven steps. ④“Our study shows that creating something like starch is possible in a laboratory, and this technology may be helpful in many areas,” said Ma. ⑤This method makes it possible to produce food in factories instead of traditional farming. This will not only help make plenty of food, but also save water and land. It may also help recycle CO₂ to deal with climate change, according to China Daily. ⑥The study can be helpful in space, too. Astronauts may no longer need to worry about their food as they travel in space. They may simply turn the CO₂ they breathe out into the food they eat! 根据语篇内容，选择最佳选项。 1．What important breakthrough have the scientists made recently? A．They found a new way to grow corn faster. B．They turned CO₂ into starch. C．They made a kind of plant. 2．How many steps do the plants usually take to produce starch? A．Eleven. B．Sixty. C．Six. 3．What are the advantages of this new technology in Paragraph 5? ①Helping make plenty of food. ②Saving water and land. ③Helping recycle CO₂ to deal with climate change. ④Making food taste better. A．①②③ B．①②④ C．①③④ 4．What’s the writer’s attitude (态度) about this technology in the end? A．Worried. B．Uninterested. C．Hopeful. 5．What can we infer (推断) from the text? A．It needs more water and land than traditional farming. B．It may help solve the food problem for astronauts in space. C．It has been widely used in food factories around the world. ①Some animals can easily find their way home after a long journey. How do they make it? Scientific research shows that they are born with certain unusual abilities for direction. ②A certain kind of ant, for example, can count their steps to avoid getting lost. They can go as far as 110 metres and bring food home. These ants live in the open desert, so they have nothing to guide them along the way. It’s like someone walking six kilometres through a dark forest. ③Some fish have an unbelievable sense of smell. They can smell even a single drop of their home water in a large sea area. Some sea birds have a similar ability. They are able to make a smell map of their flying area. ④Some animals can sense the earth’s magnetic field (磁场), while humans can’t. This magnetic field guides a certain kind of fish when they swim a long way to a place and then back. How can this kind of fish do that? It is still a mystery. Scientists have no good answers yet. ⑤However, animals with such unusual abilities still have difficulty dealing with environmental changes caused by human activities. For example, many birds depend on stars for direction, but they get lost easily at night when city lights are kept on all night. To solve this problem, we can simply turn off some lights at night. Clearly, one small act of humans may mean a lot to animals. 根据语篇内容，选择最佳选项。 1．How can a certain kind of ants find their way? A．By counting their steps. B．By imagining the way. C．By bringing food together. 2．Which kind of animals use the magnetic field to find their way? A．Sea birds. B．A certain kind of fish. C．Frogs near the lake. 3．What’s the structure (结构) of the passage? A． B． C． 4．Which can be the best title for the passage? A．Birds’ Sense of Light B．Animals’ Sense of Direction C．Animals’ Sense of Magnetic Field 5．Where is this passage most probably from? A．A storybook. B．An art magazine. C．A science magazine. 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 $
