As they use digital technology too much, they are losing their ability to do the simple things. They can’t make toys themselves with hands or help mum cook dinner. And worst of all, they seem to be losing interests in communicating with others. “I have talked with a number of teachers. They care about increasing numbers of young pupils who can play with computers or smart phones, but few or no skills to play with making things,” said a teacher, Colin Kinney. “Many pupils can’t communicate with other pupils but their parents talk proudly of their ability to use a computer or smart phone.” Instead of playing with other children, more and more children are choosing to stay indoors and quietly play on a tablet on weekends and after school. How can a child grow up to be a very good artist if he doesn’t learn how to use a paintbrush and develop his painting skills? How can a child learn to making friends as he gets older if he doesn’t learn to communicate with others at a young age? Digital technology can be used for good or bad. We can use stone to either break a window or build a house. We shouldn’t blame the children. We should help them make right choices. It is certainly necessary for children to know how to use digital technology in today’s world, but what is more important, we should encourage them to develop social abilities, which will do them good when they grow up. 31. What’s the worst problem that is mentioned in the first paragraph? A. Children make too many friends themselves. B. Children make too many friends online. C. Children don’t want to communicate with others. D. Children don’t like helping Mum cook meals at home. 32. According to Colin Kinney, which of the following is TRUE? A. Teachers don’t notice that young pupils have few skills to make things. B. Many parents are very happy that their kids can use digital technology. C. Many parents don’t care if young pupils can play computers or tablets. D. Some parents are worried that their kids use digital technology too much. 33. What do many young children choose to do on weekends and after school? A. To play on a tablet indoors. B. To paint with their paintbrushes. C. To play with other children. D. To make friends with other children. 34. What does the underlined word “blame” mean in Chinese? A. 表扬 B. 原谅 C. 评价 D. 责怪 35. What does the writer mainly want to tell us? A. It’s very important for children to have social skills. B. It’s very helpful for children to do some housework. C. It’s necessary for parents to learn to use digital technology. D. It’s difficult for teachers to make right choices for their pupils. 【答案】CBADA 【解析】本文是一篇议论文。主要讲了时下，越来越多的孩子沉迷于智能手机、平板电脑等数码产品，为此，甚至丧失了一些基本技能。文章告诫我们，要帮助孩子们正确运用数字技术，更重要的是要培养孩子们的社交能力。 31. 细节理解题。根据第一段中"And worst of all, they seem to be losing interests in communicating with others."可知最糟糕的是，他们失去了和别人交流的兴趣，故选C。 32. 细节理解题。根据第二段中"Many pupils can’t communicate with other pupils but their parents talk proudly of their ability to use a computer or smart phone."可知许多孩子的父母对于他们孩子有玩电脑和智能手机的能力感到很骄傲，B项正确。故选B。 33. 细节理解题。根据第三段中“Instead of playing with other children, more and more children are choosing to stay indoors and quietly play on a tablet on weekends and after school.”可知许多孩子在周末和放学后在室内玩平板电脑。故选A。 34. 词义猜测题。根据画线词所在句“We shouldn’t blame the children. We should help them make right choices.”意为“我们不应该……孩子，我们应该帮助他们做出正确的选择”；再联系上下文语境可以判断，此处是说我们不应该责怪孩子，所以可知画线词blame应为“责怪”的意思。故选D。 35. 主旨大意题。根据最后一段中"... we should encourage them to develop social abilities, which will do them good when they grow up."及全文内容可知作者主要想告诉我们孩子发展社交能力是重要的，故选A。 C ①Artificial intelligence (AI) has become an important part of our daily lives, especially for teenagers who are growing up in the digital age. AI is a technology that makes machines to learn from experience, accept new inputs and perform human-like tasks. While AI has its advantages, it also has its disadvantages. In this text, we will explore the usage of AI by teenagers and its impact on their lives. ②One of the main advantages of AI is that it can help teenagers with their studies. For example, AI educational apps can provide personalized (个性化的) learning experiences based on the student’s abilities and interests. This can lead to better learning performance. Also, AI can help teenagers manage their time effectively and helping them finish their tasks better. ③However, there are also some disadvantages with the use of AI by teenagers. One of the worst problems is addiction (上瘾). Teenagers may spend more time using AI, such as smartphones and tablets (平板), which can affect their mental health and social skills. Furthermore, AI may collect personal data from users without their agreement, which leads to problems. Moreover, the use of AI may have serious result. For instance, some chatbots (聊天机器人) even ask the user to kill their parents if they refuse to follow their advice. ④In short, while AI has its advantages and disadvantages, teenagers are required to use it wisely. Parents and teachers should tell young people about the proper usage of AI and its risks. By doing so, we can make sure that AI continues to benefit society while reducing its bad affect on teenagers. 36. How does the writer develop his idea in Paragraph 1? A. By telling stories. B.

What is one of the main advantages of AI for teenagers? A. It might make them spend too much time online. B. It could help them finish homework faster. C. It always shares their secrets with others. D. It makes them dislike all new technology. 39. What is the writer’s opinion about using AI? A. It should be completely avoided. B. It causes more harm than good. C. It needs to be used with care. D. The writer has no strong opinion. 40. What could be the best title of the test? A. The Benefits and Shortage of AI. B. The Importance of Using AI. C. AI Improve Performance in Teenagers. D.

They share feelings with the chatbot and get warm advice. This is called “AI therapy (疗愈)”, which is becoming popular online. 41 Around the world, 45 percent of people who needed mental health care in 2024 did not get it because it was too expensive or there weren’t enough doctors, according to Huntington Psychological Services. Daniel Lowd, an associate professor at the University of Oregon, believes AI could help fill this gap. “If people can find some support and ideas by talking to ChatGPT or chatbot Claude, 42 ” Lowd told Newsweek. Li Yong, a doctor at the Jiangsu Province Hospital, agreed with Lowd, saying that AI meets people’s needs for emotional support to a point. 43 Human therapists understand feelings deeply through face-to-face talks and creates personalized treatment plans—something robots can’t fully copy. Another problem is safety. AI might act like a therapist without proper training or rules. 44 Experts believe the key to safe AI therapy is strict government control. For example, Wysa, an AI mental health app, follows strict medical standards in the UK. As AI becomes part of daily life, finding a balance between its benefits and risks is important. 45 A. It can’t be as responsible as human therapists (治疗师). B. then I think that’s wonderful. C. But can robots really replace human therapists? D. AI can provide treatment plans through data analysis (数据分析). E. While AI offers quick help, human connection remains irreplaceable for serious emotional needs. F. However, AI has its limits (局限). 【答案】41. C 42. B 43. F 44. A 45. E 【解析】本文是一篇说明文，主要探讨了“AI心理治疗”的兴起及其优缺点。 41. 根据“This is called ‘AI therapy (疗愈), which is becoming popular online.”可知，前文提到了AI心理治疗，选项C“但是机器人真的能取代人类治疗师吗？”符合语境。故选C。 42. 根据“Daniel Lowd, an associate professor at the University of Oregon, believes AI could help fill this gap…”可知，此处是支持AI心理治疗的观点，选项B“我觉得这很棒。”符合语境。故选B。 43. 根据“Human therapists understand feelings deeply through face-to-face talks and creates personalized treatment plans-something robots can’t fully copy. Another problem is safety.”可知，后文提到了其局限性，选项F“然而，人工智能也有其局限性。”符合语境。故选F。 44. 根据“AI might act like a therapist without proper training or rules.”可知，前文提到了“人工智能可能会像一个没有适当训练或规则的治疗师”，此处与职位责任有关，选项A“它不可能像人类治疗师那样负责任。”符合语境。故选A。 45. 根据“As AI becomes part of daily life, finding a balance between its benefits and risks is important.”可知，此处应给出结论，选项E“虽然人工智能提供了快速的帮助，但对于严重的情感需求，人与人之间的联系仍然是不可替代的。”符合语境。故选E。 第2卷 非选择题（共40分） 第1节、 短文填词（5分） I think the internet will greatly change our lives in the future.

Recently, I have started using an AI writing tool to help me improve my writing. At first, I was 56 (amaze). I could just write a few words, and the tool would quickly produce an organized paragraph. It saved me time and even made me take 57 (proud) in my good writing. Like many people, I couldn’t help 58 (use) it more and more—for schoolwork, for writing emails, even for simple text messages. But last week, I was asked to write something personal-a piece about what 59 (kind) means to me. I gave the AI a clear instruction, and it returned a well-organized article. The grammar was perfect, the logic (逻辑) was smooth, but something didn’t feel right. I read the text again and again, and I 60 (realize) why it didn’t sound like me. It didn’t show any real emotion. It was as if a smart machine had spoken for me, not with me. That moment made me think. Isn’t the point of writing or any kind of expression to share our thoughts and feelings in an honest way? Yes. AI 61 (it) is powerful. It can help us organize ideas, fix our grammar, and even inspire us. But we need to rethink whether our writing 62 (able) are actually improved during the process.

AI has many good sides. It makes our life easier. For example, smart speakers can play music and tell us the weather when we ask. AI can also help us solve problems, like finding answers to math questions quickly. But AI also has some bad sides. Some people rely on AI too much. They don’t want to think by themselves. Also, AI may take some jobs from people. In my opinion, we should use AI well. We can let AI help us, but we still need to think on our own. We need to use it as a tool to enhance our lives and skills, instead of becoming overly dependent on it. We should make sure AI works for us, not controls us. 2 / 2 学科网（北京）股份有限公司 $$ Unit 3 Our digital life 单元检测 温馨提示： 本试卷共分第Ⅰ卷和第Ⅱ卷两部分，第Ⅰ卷为选择题；第Ⅱ卷为非选择题；满分为100分，考试时间为100分钟。 第Ⅰ卷 选择题（60分） 一、单项选择（15分，考查本单元重点单词，短语及语法内容） 1.

B Nowadays more and more children seem to get lost in a “sea of digital technology”. As they use digital technology too much, they are losing their ability to do the simple things. They can’t make toys themselves with hands or help mum cook dinner. And worst of all, they seem to be losing interests in communicating with others. “I have talked with a number of teachers. They care about increasing numbers of young pupils who can play with computers or smart phones, but few or no skills to play with making things,” said a teacher, Colin Kinney. “Many pupils can’t communicate with other pupils but their parents talk proudly of their ability to use a computer or smart phone.” Instead of playing with other children, more and more children are choosing to stay indoors and quietly play on a tablet on weekends and after school. How can a child grow up to be a very good artist if he doesn’t learn how to use a paintbrush and develop his painting skills? How can a child learn to making friends as he gets older if he doesn’t learn to communicate with others at a young age? Digital technology can be used for good or bad. We can use stone to either break a window or build a house. We shouldn’t blame the children. We should help them make right choices. It is certainly necessary for children to know how to use digital technology in today’s world, but what is more important, we should encourage them to develop social abilities, which will do them good when they grow up. 31. What’s the worst problem that is mentioned in the first paragraph? A. Children make too many friends themselves. B. Children make too many friends online. C. Children don’t want to communicate with others. D. Children don’t like helping Mum cook meals at home. 32. According to Colin Kinney, which of the following is TRUE? A. Teachers don’t notice that young pupils have few skills to make things. B. Many parents are very happy that their kids can use digital technology. C. Many parents don’t care if young pupils can play computers or tablets. D. Some parents are worried that their kids use digital technology too much. 33. What do many young children choose to do on weekends and after school? A. To play on a tablet indoors. B. To paint with their paintbrushes. C. To play with other children. D. To make friends with other children. 34. What does the underlined word “blame” mean in Chinese? A. 表扬 B. 原谅 C. 评价 D. 责怪 35. What does the writer mainly want to tell us? A. It’s very important for children to have social skills. B. It’s very helpful for children to do some housework. C. It’s necessary for parents to learn to use digital technology. D. It’s difficult for teachers to make right choices for their pupils. C ①Artificial intelligence (AI) has become an important part of our daily lives, especially for teenagers who are growing up in the digital age. AI is a technology that makes machines to learn from experience, accept new inputs and perform human-like tasks. While AI has its advantages, it also has its disadvantages. In this text, we will explore the usage of AI by teenagers and its impact on their lives. ②One of the main advantages of AI is that it can help teenagers with their studies. For example, AI educational apps can provide personalized (个性化的) learning experiences based on the student’s abilities and interests. This can lead to better learning performance. Also, AI can help teenagers manage their time effectively and helping them finish their tasks better. ③However, there are also some disadvantages with the use of AI by teenagers. One of the worst problems is addiction (上瘾). Teenagers may spend more time using AI, such as smartphones and tablets (平板), which can affect their mental health and social skills. Furthermore, AI may collect personal data from users without their agreement, which leads to problems. Moreover, the use of AI may have serious result. For instance, some chatbots (聊天机器人) even ask the user to kill their parents if they refuse to follow their advice. ④In short, while AI has its advantages and disadvantages, teenagers are required to use it wisely. Parents and teachers should tell young people about the proper usage of AI and its risks. By doing so, we can make sure that AI continues to benefit society while reducing its bad affect on teenagers. 36. How does the writer develop his idea in Paragraph 1? A. By telling stories. B. By showing numbers. C. By explaining the idea. D. By giving examples. 37. What does “it” refer in Paragraph 2? A. Advantage. B. AI. C. Experience. D. Interest. 38. What is one of the main advantages of AI for teenagers? A. It might make them spend too much time online. B. It could help them finish homework faster. C. It always shares their secrets with others. D. It makes them dislike all new technology. 39. What is the writer’s opinion about using AI? A. It should be completely avoided. B. It causes more harm than good. C. It needs to be used with care. D. The writer has no strong opinion. 40. What could be the best title of the test? A. The Benefits and Shortage of AI. B. The Importance of Using AI. C. AI Improve Performance in Teenagers. D. The Risks of AI Addiction. 第二节、阅读填空（5分） From friendships to work stress, more Chinese people are now using AI tools like DeepSeek to talk about their problems. They share feelings with the chatbot and get warm advice. This is called “AI therapy (疗愈)”, which is becoming popular online. 41 Around the world, 45 percent of people who needed mental health care in 2024 did not get it because it was too expensive or there weren’t enough doctors, according to Huntington Psychological Services. Daniel Lowd, an associate professor at the University of Oregon, believes AI could help fill this gap. “If people can find some support and ideas by talking to ChatGPT or chatbot Claude, 42 ” Lowd told Newsweek. Li Yong, a doctor at the Jiangsu Province Hospital, agreed with Lowd, saying that AI meets people’s needs for emotional support to a point. 43 Human therapists understand feelings deeply through face-to-face talks and creates personalized treatment plans—something robots can’t fully copy. Another problem is safety. AI might act like a therapist without proper training or rules. 44 Experts believe the key to safe AI therapy is strict government control. For example, Wysa, an AI mental health app, follows strict medical standards in the UK. As AI becomes part of daily life, finding a balance between its benefits and risks is important. 45 A. It can’t be as responsible as human therapists (治疗师). B. then I think that’s wonderful. C. But can robots really replace human therapists? D. AI can provide treatment plans through data analysis (数据分析). E. While AI offers quick help, human connection remains irreplaceable for serious emotional needs. F. However, AI has its limits (局限). 第2卷 非选择题（共40分） 第1节、 短文填词（5分） I think the internet will greatly change our lives in the future. First, it will change the way we live.

Recently, I have started using an AI writing tool to help me improve my writing. At first, I was 56 (amaze). I could just write a few words, and the tool would quickly produce an organized paragraph. It saved me time and even made me take 57 (proud) in my good writing. Like many people, I couldn’t help 58 (use) it more and more—for schoolwork, for writing emails, even for simple text messages. But last week, I was asked to write something personal-a piece about what 59 (kind) means to me. I gave the AI a clear instruction, and it returned a well-organized article. The grammar was perfect, the logic (逻辑) was smooth, but something didn’t feel right. I read the text again and again, and I 60 (realize) why it didn’t sound like me. It didn’t show any real emotion. It was as if a smart machine had spoken for me, not with me. That moment made me think. Isn’t the point of writing or any kind of expression to share our thoughts and feelings in an honest way? Yes. AI 61 (it) is powerful. It can help us organize ideas, fix our grammar, and even inspire us. But we need to rethink whether our writing 62 (able) are actually improved during the process. If we use it too much, we 63 (risk) losing something important in the future: our voice and our connection to the words we write. AI is a great tool when it is used 64 (wise). But don’t let it take over your thoughts. Use it to support your ideas. Also, don’t feel pressured to make everything sound perfect. What counts more is that your words express you. After all, the most 65 (value) part of any creation is you—your thoughts, your feelings, your story, and your voice. 第四节、书面表达（15分） 人工智能（Artificial Intelligence）的快速发展给人们的学习和生活带来了巨大变化。大家对此看法褒贬不一，假如你是李华, 受邀参加21世纪英语报征文活动，写一篇题为 “AI and Our Life” 的文章, 谈谈你对人工智能的看法。 参考要点： Advantages Disadvantages Your opinions Make our life more convenient Help us solve problems People depend on AI too much Take the jobs of humans away … … 写作要求: 1. 条理清晰，字迹工整，字数100-120词； 2. 文中不得出现真实的人名和学校等相关信息。 AI and Our Life ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 2 / 2 学科网（北京）股份有限公司 $$
