Students went there to read, borrow books or do homework. Last year, however, Hilltop Middle School decided to build a digital library. At first, some teachers were not sure whether students would like the new idea. They thought students might spend too much time looking at screens. But after several months, the digital library became one of the most 1. ________ places in the school. Students can now use tablets to read e-books, watch educational videos and look for information.

In one city, smart bus stops are helping solve this problem. Each smart bus stop has a digital screen. The screen shows when the next buses will arrive and whether there are many passengers on them. The information comes from small devices on the buses. These devices send their location to the city traffic network every few seconds. The bus stops also have lights that turn on automatically when it gets dark. Some even have solar panels, so they can produce some of their own electricity. The new system has made travelling more convenient. Passengers no longer need to guess when a bus will come. They can decide whether to wait, walk or take another bus. However, the system is not perfect. If the network stops working, the screen may show no information. Some older people also say the screens are difficult to read. The city government says it will continue improving the system because most passengers think the smart bus stops make travelling easier. 1. Where does the information on the digital screens come from? A. The passengers’ phones. B. Solar panels. C. The bus drivers. D. Devices on the buses. 32. Why do some smart bus stops use solar panels? A. To make buses move faster. B. To provide electricity. C. To collect passengers’ information. D. To make the screens bigger. 33. What problem is mentioned in the passage? A. The buses are too expensive. B. The stops are too far apart. C. The system may not work without the network. D. Passengers cannot see where buses go. 34. What is the main purpose of the passage? A. To introduce how smart bus stops work. B. To explain why buses are better than cars. C. To warn people not to use public transport. D. To compare buses in different countries. B Fourteen-year-old Daniel used to spend almost every free minute online. He watched short videos before school, checked messages during lunch and played online games after dinner. One day, Daniel noticed that he often felt tired in class. He also found it difficult to finish his homework because he checked his phone every few minutes. His parents suggested that he try a “screen-free hour” every evening. At first, Daniel thought the idea was terrible. He worried that he might miss important messages. However, he agreed to try it for one week. During that hour, Daniel put his phone in another room. He used the time to read, draw and talk with his family. After several days, he found that he finished his homework faster and slept better. Daniel did not stop using digital devices. In fact, he still believes the Internet is extremely useful. He uses it to search for information, learn guitar and stay in touch with friends. But now he tries to control how much time he spends online. “Technology wasn’t the real problem,” Daniel says. “The problem was that I wasn’t using it wisely.” 35. What caused Daniel’s problem with homework? A. He did not understand his lessons. B. His parents gave him too much work. C. His homework was too difficult. D. He checked his phone too often. 36. The word “screen-free” probably means ________. A. without using digital screens B. watching screens for free C. repairing broken screens D. using a larger screen 37. What can we infer from the passage? A. Daniel now dislikes the Internet. B. Daniel’s parents took away his phone forever. C. Changing digital habits improved Daniel’s daily life. D. Daniel spends no time online now. 38. Which statement best describes Daniel’s opinion at the end? A. All technology is harmful. B. Technology is useful if people use it properly. C. Teenagers should never use phones. D. Online games are the best way to relax. C The Internet allows us to find information more quickly than ever before. With only a few clicks, students can read news, find answers and learn about almost any subject. However, being able to find information does not always mean understanding whether it is true. Imagine that you see two online articles about the same health problem. One article is written by a hospital. It explains where the information comes from and gives the names of doctors. The other article gives no writer’s name and says, “This treatment works for everyone!” Which one should you trust? Digital literacy means more than knowing how to use a phone or computer. It also means knowing how to evaluate online information. Before believing something, readers should ask several questions: Who wrote it? Why was it written? Is there evidence? Do other reliable sources say the same thing? Another problem is that social media often shows people information that matches what they already like or believe. Over time, they may see fewer different opinions. This can make people think that their own view is the only correct one. For this reason, good digital readers do not simply accept the first answer they find. They compare different sources and think carefully before forming an opinion. 39. Why does the writer mention the two health articles? A. To teach readers how to become doctors. B. To give an example of evaluating online information. C. To show that hospitals always make mistakes. D. To prove that online health information is useless. 40. What does “reliable” most probably mean in Paragraph 3? A. Interesting and popular. B. Easy to understand. C. Able to be trusted. D. New and unusual. 41. According to Paragraph 4, what may happen on social media? A. People may mainly see ideas similar to their own. B. People always change their opinions. C. People can no longer find any information. D. Everyone receives exactly the same content. 42. Which title is the best for the passage? A. How to Become Popular Online B. Why Computers Are Becoming Faster C. The History of Social Media D. Think Before You Believe D Many digital services learn from what people do online. A music app remembers the songs you listen to. A video app notices what you watch. An online shop records the things you look at. It then uses this information to recommend what you may like next. This can be helpful. Without recommendations, people might spend a long time searching through thousands of songs, videos or products. A good system can quickly show users something that matches their interests. But recommendations can also quietly influence people’s choices. Imagine that an app always shows you the same type of music. After some time, you may stop discovering other kinds. Or suppose an online shop keeps recommending expensive products because you once clicked on one. You may start to believe those are the only suitable choices. This does not mean recommendation systems are bad. The important point is to understand that they are making choices about what information we see. They do not show us everything. Some technology experts suggest that users should sometimes search for things outside their usual interests. They also recommend checking why an app is showing certain content when that information is available. Digital technology can make life easier, but convenience should not replace independent thinking. A smart user does not only ask, “What does the app recommend?” The smart user also asks, “What might I not be seeing?” 43. Why are recommendation systems useful according to Paragraph 1? A. They help people find suitable content more quickly. B. They make all online products cheaper. C. They prevent users from making choices. D. They show everyone the same information. 44. What does the word “influence” in Paragraph 2 most probably mean? A. Stop completely. B. Have an effect on. C. Copy exactly. D. Learn about. 45. What can we infer from the passage? A. Recommendation systems always know what is best for us. B. People should never use recommendation systems. C. Recommendations may limit what users see without them noticing. D. Online shops should stop collecting all information. 46. What is the writer’s main opinion? A. Technology should make all our decisions for us. B. Convenience is more important than independent thinking. C. Users should understand technology and keep thinking for themselves. D. Recommendation systems are the greatest digital breakthrough. 五、阅读还原（共4小题，每小题2分，共8分） Digital devices are now an important part of our daily lives.

Their teacher did not simply ask them to read a textbook. Instead, each group had to choose one important development in computer history and explain why it mattered. Amy’s group chose the microchip. At first, they only knew that microchips were small. After doing research, they discovered that microchips allowed computers to become much smaller and faster. They also learned that microchips are now used in many everyday devices, including phones, cars and washing machines. Ben’s group studied early computers. They were surprised to learn that some early computers were as large as a room. Compared with modern laptops, they were much slower and could do far fewer things. Another group studied smartphones. They interviewed parents and grandparents about life before smartphones became common. Many adults said that smartphones made communication easier, but several also felt that people now spent less time talking face to face. At the end of the project, the students created a digital exhibition. Instead of simply listing dates, they included pictures, short videos and interviews. Their teacher was pleased because the project helped students understand not only how computers changed, but also how computer technology changed people’s lives. 1. What did each group need to choose for the project? __________________________________________________________ 2. Why were microchips important to the development of computers? ___________________________________________________________ 3. How were some early computers different from modern laptops? ___________________________________________________________ 4. What negative effect of smartphones did some adults mention? ___________________________________________________________ 5. What did the students include in their digital exhibition? _________________________________________________________ 七、书面表达(共20分) 随着互联网和智能设备的发展，我们的生活发生了很大变化。网络给学习和生活带来了便利，但也可能带来一些问题。请以 “The Internet in Our Lives” 为题，写一篇英语短文。 内容包括：互联网给我们带来的至少 两点好处；互联网可能带来的至少 两点问题；你认为中学生应该怎样合理使用互联网；表达自己的观点。 要求：词数 80—100词；内容完整，语句通顺；可适当发挥；不得出现真实姓名和学校名称。 ___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 参考答案 一、用所给词的适当形式填空 1. easier 6. most useful 7. changes 8. wisely 9. smoothly 10. really 11. treatment 12. sharing 13. warned 14. powerful 二、根据汉语意思写单词 1. network 15. laptop 16. payment 17. data 18. message 19. interview 20. social 21. microchip 22. breakthrough 23. download 三、完形填空 1-5 D B C B A 6-10 D B A C A 四、阅读理解 A 1-4 D B C A B 5-8 D A C B C 9-12 B C A D D 13-16 A B C C 五、阅读还原 1-4 D B A C 六、阅读回答问题 1.

It has both positive and negative effects on teenagers. On the one hand, we can use the Internet to find information and learn new things. It also helps us stay in touch with our friends and family. On the other hand, some students spend too much time on social media or online games. Also, not all information online is reliable. In my opinion, we should use the Internet wisely. We should control our screen time, protect our personal information and check information carefully before believing it. The Internet is a useful tool if we use it in the right way. 学科网（北京）股份有限公司 $
