The reason is that AI is getting more and more important in our daily lives. It changes how we live and work, like the smart apps in our phones. First, schools need to start AI classes. For young primary school kids, they can learn basic AI ideas and try simple AI tools. For example, they can use a drawing app that colors pictures by itself in their AI project clubs. When students go to junior high school, they will learn more about how AI works. They can use AI to solve study and life problems. In senior high school (高中), students can try to make small AI projects and do simple research. These let them see the fun and new parts of AI. 184 schools worked as test schools in 2024. So far, they have tried different ways to teach AI. Students can visit the AI labs and showrooms in universities and technology companies. Teachers are trying to use AI in daily lessons and tests. Besides, the national online study platform includes a new AI part now. In these ways, students all over the country can see good AI learning materials. In Minister Huai Jinpeng’s opinion, AI is like a “golden key” for education. It brings both great chances and some new challenges. All these efforts are to help Chinese students get ready for the future world where AI is everywhere. In the future, more schools will join in AI education. With these plans, students can learn AI well and face the AI world easily. 34．Lin Jin is 9 years old and Liu Ming is 14. What can they mostly do with AI according to the passage?

For example, they can use a drawing app that colors pictures by itself”以及“When students go to junior high school, they will learn more about how AI works. They can use AI to solve study and life problems.”林金9岁属于小学生，刘明14岁属于初中生，因此林金可用简单绘画应用，刘明可用AI解决学习与生活问题。 35．第三段的内容： “Students can visit the AI labs and showrooms in universities and technology companies.”这对应了选项①和②。 “Teachers are trying to use AI in daily lessons and tests.” 这对应了选项③。 “Besides, the national online study platform includes a new AI part now.

It brings both great chances and some new challenges.”因此“golden key”比喻的是AI为教育带来的机遇与挑战并存的特性。 37．末段首句点明最终目标：“All these efforts are to help Chinese students get ready for the future world where AI is everywhere.”因此所有努力的最终目的是帮助学生为未来AI世界做好准备。 38．全文结构为：第一段引出话题（AI教育的重要性），第二段介绍不同学段的教学安排，第三段介绍试点学校的实践方式，第四段总结目标与展望；符合①—②—③—④的结构。 六、完形填空(共12分) Do you often feel tired after staring at a screen for too long? You are not alone. Many students today spend hours each day on their phones, computers, or tablets. While technology brings us many 39 , it also has some negative effects on our health. One common problem is eye strain. When you look at a screen for a long time, your eyes have to work harder. This can cause headaches and dry eyes. To 40 this, doctors suggest the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Another issue is that too much screen time can affect your sleep. The blue light from screens can fool your brain into thinking it’s still daytime. This makes it harder to fall 41 at night. Experts recommend turning off electronic devices at least one hour before bedtime. 42 , spending too much time online can also influence your mental health. Comparing yourself to others on social media might make you feel unhappy or lonely. It is important to remember that what people post online is not always the 43 picture of their lives. So what can we do? The key is to find a balance. Enjoy the benefits of technology, but don’t forget to take breaks, go outside, and spend time with family and friends in the 44 world. Your eyes, your mind, and your body will thank you. 39．A．problems B．advantages C．excuses D．worries 40．A．cause B．increase C．prevent D．ignore 41．A．asleep B．sleepy C．sleeping D．slept 42．A．However B．Therefore C．Besides D．Otherwise 43．A．full B．perfect C．simple D．dark 44．A．digital B．real C．virtual D．online 【答案】39．B 40．C 41．A 42．C 43．A 44．B 【导语】本文是一篇说明文，主要探讨过度使用屏幕对健康的负面影响及如何平衡科技与生活，提出具体建议。 【详解】39．句意：虽然科技给我们带来很多好处，但它也对我们的健康产生一些负面影响。 根据后半句的转折与negative effects，advantages（优点、好处）形成前后对比。problems问题，excuses借口，worries担忧，均不符合上下文。 40．句意：为了防止这种情况，医生提出了20-20-20法则。 this指代前文的头痛与干眼，prevent（预防、防止）符合语境。cause造成，increase增加，ignore忽视，均不符合上下文。 41．句意：这会让人在夜里更难入睡。 固定搭配fall asleep表示“入睡”。sleepy困倦的，sleeping睡觉，slept是sleep的过去式，均不符合搭配。 42．句意：除此之外，上网时间过长也会影响你的心理健康。 本段是补充第二条危害，Besides（此外）用于递进。However然而，Therefore因此，Otherwise否则，均不符合逻辑。 43．句意：重要的是要记住，人们在网上发布的内容并不总是他们生活的完整画面。 根据常识及语境，社交媒体只展示部分生活，并非全貌。“the full picture”为固定搭配，意为“全貌”。 44．句意：享受科技带来的好处，但不要忘记休息，走出去，在现实世界中与家人朋友共度时光。 根据“go outside”及与前文“online”对比，此处指脱离网络的现实世界。real world表示“现实世界”，和线上虚拟生活形成对比。digital数字的，virtual虚拟的，online线上的，均不符合上下文。 七、任务型阅读(共12分) Have you ever heard of a “time bank”? It’s not a place that stores money. Instead, it’s a community system where people exchange services using time as the currency (货币). Here’s how it works: When you do one hour of service for someone in the community, you earn one “time dollar”. You can then spend that time dollar to receive one hour of service from someone else. The type of service doesn’t matter. One hour of tutoring English equals one hour of dog walking equals one hour of fixing a computer. The first modern time bank was started by lawyer Edgar Cahn in the United States in 1980. He believed that money doesn’t measure the true value of all work. Caring for an elderly neighbor, teaching a child to read, or helping someone learn to use a computer—these are valuable contributions that the regular economy often ignores. Today, time banks have spread to over 30 countries. In Shanghai, a community started a time bank in 2018. Retired teachers offer free tutoring to students. In return, students’ parents help the elderly with grocery shopping or technology problems. Young professionals teach English or computer skills to seniors, and seniors share their life experience and cooking skills. Studies show that time banks do more than just exchange services. They build stronger communities. When people help each other, they feel more connected. Loneliness decreases, trust increases, and neighbors who never spoke before become friends. However, time banks also face challenges. Some people worry about quality control—what if someone does a poor job? Others are concerned that time banks might replace the real economy. Supporters argue that time banks don’t replace paid work; they add value by recognizing and encouraging community contributions. For teenagers, time banks can be especially meaningful. Students can earn time dollars by tutoring younger children, helping with community clean-ups, or teaching seniors how to use smartphones. In return, they can receive help with subjects they find difficult, or even earn music lessons from a neighbor. It teaches responsibility, builds confidence, and shows that everyone has something valuable to offer. 45．What is a time bank? 46．How do people earn “time dollars” in a time bank? 47．According to Edgar Cahn, what problem does the regular economy have? 48．List one benefit of time banks mentioned in the passage. 49．Do you think time banks would work well in your community? Why or why not? (Give at least one reason) 50．Task 2: After reading the passage, what do you think is the most important quality for a successful time bank? Please explain your understanding. (About 30 words) 【答案】45．A time bank is a community system where people exchange services using time as the currency. 46．They earn one time dollar for each hour of service they do for someone in the community. 47．The regular economy ignores valuable contributions like caring for neighbors or teaching children. 48．It builds stronger communities/It decreases loneliness/It increases trust/It helps neighbors become friends. (Any one) 49．Yes, I think it would work well because many neighbors already help each other informally. A time bank would just make the system more organized. (Or No, I don’t think so because people in my community are very busy and may not have time to volunteer.) 50．I think trust is the most important quality. Without trust, people won’t believe that others will repay their help. A time bank depends on everyone keeping their promises. 【导语】这是一篇说明文。文章主要介绍了“时间银行”的概念、运作方式、起源、好处、面临的挑战以及对青少年的意义。 【详解】45．根据第一段中“Instead, it’s a community system where people exchange services using time as the currency.”可知，时间银行是一个用时间作为货币交换服务的社区系统。 46．根据第二段中“When you do one hour of service for someone in the community, you earn one ‘time dollar’.”可知，人们通过为社区某人提供一小时服务来赚取时间美元。 47．根据第三段中“He believed that money doesn’t measure the true value of all work... these are valuable contributions that the regular economy often ignores.”可知，常规经济的问题在于忽视了有价值的贡献或金钱无法衡量所有工作的真正价值。 48．根据第五段中“They build stronger communities. When people help each other, they feel more connected. Loneliness decreases, trust increases...”可知，时间银行的好处包括建立更强大的社区、减少孤独感或增加信任。 49．本题为开放性问题，答案不唯一，言之有理即可。根据第五段提到的好处，可以认为时间银行能促进邻里关系。 50．本题要求写出成功的时间银行最重要的品质并解释，为开放性问题，答案不唯一，言之有理即可。字数约30词。根据第六段提到的质量控制和信任问题，信任是基础。 八、书面表达(共23分) 51．以“Digital Life in My Eyes”为题，描述你眼中的数字生活，包括数字生活带来的好处、存在的问题。(80词左右) _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】例文 Digital Life in My Eyes In my eyes, digital life has both advantages and disadvantages. On one hand, it brings us a lot of convenience. We can shop online without going out, study online to learn more knowledge and keep in touch with friends easily through social media. On the other hand, there are some problems. Some people are addicted to digital devices, which affects their study and work. Also, there is a risk of personal information leakage. 【详解】写作步骤 [第一步：审题立意] 确定文体：观点类议论文，以一般现在时为主 明确要点：数字生活的好处、存在的问题 确定人称：第一人称（I/we） 注意事项：80词左右 [第二步：构思布局] 采用“总—分”结构： 开头段：总起句，点明数字生活兼具优缺点 主体段：分两部分阐述，先写数字生活的便利，再写存在的问题，逻辑清晰，层次分明 [第三步：要点展开] 要点一：数字生活的好处 给我们带来很多便利：brings us a lot of convenience /makes our life much easier /brings great convenience to our daily life 足不出户线上购物：shop online without going out /buy things online at home /shop on the Internet without leaving home 在线学习，获取更多知识：study online to learn more knowledge /take online courses to get more information /learn more things through the Internet 通过社交媒体轻松和朋友保持联系：keep in touch with friends easily through social media /communicate with friends conveniently online /stay connected with friends easily via social apps 要点二：数字生活的问题 沉迷数字设备：be addicted to digital devices /spend too much time on electronic products /get hooked on digital tools 影响学习和工作：affects their study and work /has a bad influence on schoolwork and jobs /influences their study and work negatively 存在个人信息泄露的风险：there is a risk of personal information leakage /our private information may be leaked online /our personal data might be given away / 学科网（北京）股份有限公司 $ U2暑假单元自测卷 （考试时间：90分钟 试卷满分：100分） 注意：本卷试题均采用连续编号，所有答案务必按照规定在答题纸上完成，做在练习卷上不给分。 一、语法选择(共10分) Have you ever tried a “digital detox (数字排毒)”? It means staying away from your phone, computer or tablet for a certain period of time. Many people 1 this challenge surprisingly difficult at first.

Without the noise of notifications, he noticed how beautifully the birds 4 in the trees. After lunch, some of his friends came over. They played board games together, which they 5 do often anymore because everyone is usually on their phones. During the detox, many students discovered that they had much more free time than expected. Some read books that 6 on their shelves for months. Others learned to cook simple meals. A girl named Li Wei 7 her room when she suddenly realized how much she enjoyed the quietness. By the end of the weekend, most students felt a sense of achievement.

It changes how we live and work, like the smart apps in our phones. First, schools need to start AI classes. For young primary school kids, they can learn basic AI ideas and try simple AI tools. For example, they can use a drawing app that colors pictures by itself in their AI project clubs. When students go to junior high school, they will learn more about how AI works. They can use AI to solve study and life problems. In senior high school (高中), students can try to make small AI projects and do simple research. These let them see the fun and new parts of AI. 184 schools worked as test schools in 2024. So far, they have tried different ways to teach AI. Students can visit the AI labs and showrooms in universities and technology companies. Teachers are trying to use AI in daily lessons and tests. Besides, the national online study platform includes a new AI part now. In these ways, students all over the country can see good AI learning materials. In Minister Huai Jinpeng’s opinion, AI is like a “golden key” for education. It brings both great chances and some new challenges. All these efforts are to help Chinese students get ready for the future world where AI is everywhere. In the future, more schools will join in AI education.

While technology brings us many 39 , it also has some negative effects on our health. One common problem is eye strain. When you look at a screen for a long time, your eyes have to work harder. This can cause headaches and dry eyes. To 40 this, doctors suggest the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Another issue is that too much screen time can affect your sleep. The blue light from screens can fool your brain into thinking it’s still daytime. This makes it harder to fall 41 at night. Experts recommend turning off electronic devices at least one hour before bedtime. 42 , spending too much time online can also influence your mental health. Comparing yourself to others on social media might make you feel unhappy or lonely. It is important to remember that what people post online is not always the 43 picture of their lives. So what can we do? The key is to find a balance. Enjoy the benefits of technology, but don’t forget to take breaks, go outside, and spend time with family and friends in the 44 world. Your eyes, your mind, and your body will thank you. 39．A．problems B．advantages C．excuses D．worries 40．A．cause B．increase C．prevent D．ignore 41．A．asleep B．sleepy C．sleeping D．slept 42．A．However B．Therefore C．Besides D．Otherwise 43．A．full B．perfect C．simple D．dark 44．A．digital B．real C．virtual D．online 七、任务型阅读(共12分) Have you ever heard of a “time bank”? It’s not a place that stores money. Instead, it’s a community system where people exchange services using time as the currency (货币). Here’s how it works: When you do one hour of service for someone in the community, you earn one “time dollar”. You can then spend that time dollar to receive one hour of service from someone else. The type of service doesn’t matter. One hour of tutoring English equals one hour of dog walking equals one hour of fixing a computer. The first modern time bank was started by lawyer Edgar Cahn in the United States in 1980. He believed that money doesn’t measure the true value of all work. Caring for an elderly neighbor, teaching a child to read, or helping someone learn to use a computer—these are valuable contributions that the regular economy often ignores. Today, time banks have spread to over 30 countries. In Shanghai, a community started a time bank in 2018. Retired teachers offer free tutoring to students. In return, students’ parents help the elderly with grocery shopping or technology problems. Young professionals teach English or computer skills to seniors, and seniors share their life experience and cooking skills. Studies show that time banks do more than just exchange services. They build stronger communities. When people help each other, they feel more connected. Loneliness decreases, trust increases, and neighbors who never spoke before become friends. However, time banks also face challenges. Some people worry about quality control—what if someone does a poor job? Others are concerned that time banks might replace the real economy. Supporters argue that time banks don’t replace paid work; they add value by recognizing and encouraging community contributions. For teenagers, time banks can be especially meaningful. Students can earn time dollars by tutoring younger children, helping with community clean-ups, or teaching seniors how to use smartphones. In return, they can receive help with subjects they find difficult, or even earn music lessons from a neighbor. It teaches responsibility, builds confidence, and shows that everyone has something valuable to offer. 45．What is a time bank? 46．How do people earn “time dollars” in a time bank? 47．According to Edgar Cahn, what problem does the regular economy have? 48．List one benefit of time banks mentioned in the passage. 49．Do you think time banks would work well in your community? Why or why not? (Give at least one reason) 50．Task 2: After reading the passage, what do you think is the most important quality for a successful time bank? Please explain your understanding.
