Thanks to Alvaro’s sister, who is a heart expert, his father got the 1 treatment (治疗). This inspired (鼓舞) Alvaro to learn about why misdiagnosis happens in healthcare and how to 2 it. He is now a student at Harvard Kennedy School and is learning about artificial intelligence (AI). He and his team 3 an app called PrescrAIbe. co. This app helps doctors make better 4 by predicting conditions and suggesting treatments according to a patient’s medical history. By using AI to deal with boring tasks, doctors can spend more time with patients, leading to better care. Before studying at Harvard, Alvaro 5 at a local community clinic (诊所).

Many students, especially those in junior high school, are turning to AI tools to help with their homework. While these tools can offer convenience, they also come with their own set of advantages and disadvantages. AI does bring some advantages for students. First, AI saves time. Students can quickly find answers to difficult math problems or grammar questions. Second, AI provides learning resources. For example, some tools explain solutions step by step, helping students understand topics better. Third, AI supports personalized learning. Struggling (挣扎) students can practice repeatedly with AI feedback (反馈), while advanced learners can explore harder tasks. However, there are also some disadvantages. Depending too much on AI can make students lazy and may stop them trying to solve problems independently. It’s not helpful to improve their thinking skills. This can hurt their learning in the long run. Another problem is that AI tools sometimes give wrong answers, especially for open-ended questions like essays. Lastly, using AI can lead to cheating. Copying AI-generated work without learning breaks trust between students and teachers. AI can be a helpful study tool if used wisely. Students should treat it as a guide, not a replacement for their own efforts. Balancing AI assistance with active learning is key to success. 1. What is one advantage of using AI for homework? A. It makes students lazy. B. It saves time. C. It is always exact. D. It replaces teachers. 2. What does the underlined word “personalized” in Paragraph 2 mean? A. Free of service. B. Suitable for each student. C. Very special. D. Custom-made service. 3. What is the result of students becoming overly dependent on AI? A. They might develop better problem-solving skills. B. They might struggle with traditional methods of studying. C. They might reduce their own critical thinking abilities. D. They might become more confident. 4. Why should students use AI wisely? A. To avoid understanding concepts. B. To finish homework without thinking. C. To enjoy its benefits and avoid shortcomings. D. To make AI replace their teachers. 5. What is the best title for this passage? A. The Dangers of AI in Education B. How AI Replaces Teachers C. Why Students Should Never Use AI D. The Pros and Cons of Using AI for Homework B The Internet plays a big part in human life. We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about. The list goes on and on. As far as the Internet being a part of our lives—well, that train has left the station. There is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected with high blood pressure（压力） in a young group: teenagers. The study results show that teens who spend at least 14 hours a week online may develop high blood pressure, which makes your heart and blood vessels work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause other diseases. The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 to 17 years old, took part in it. 134 of the teens were described as “heavy Internet users”. And researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first to connect heavy web use with high blood pressure. The lead researcher is Andrea Cassidy Bushrow. She said, “Using the Internet is part of our daily life, but it shouldn’t ruin us.” Ms. Cassidy Bushrow adds that it is important for teens to stop to have a rest regularly（定期地） from their computers or smartphones. She also suggests that parents shouldn’t let their children use the Internet for more than two hours a day, five days a week. 1. What does the underlined part “that train has left the station” mean in paragraph 2? A. The train has changed its course. B. There is something wrong with the station. C. The train has stopped at the wrong station. D. Life without the Internet is nowhere to be found. 2. What is paragraph 3 mainly about? A. The harm of high blood pressure. B. Ways to prevent high blood pressure. C. The advantages of using the Internet. D. The disadvantages of using the Internet. 3. Andrea Cassidy Bushrow would agree that ________. A. teenagers shouldn’t use the Internet B. the Internet will ruin human life in the future C. smartphones are more harmful than computers D. regular breaks are necessary when using the Internet 4. What can be used as the best title of the text? A. Heavy Internet users are mostly teenagers B. How to prevent teenagers from the Internet C. Too much Internet use may be bad for teenagers D.

Many students, especially those in junior high school, are turning to AI tools to help with their homework. While these tools can offer convenience, they also come with their own set of advantages and disadvantages. AI does bring some advantages for students. First, AI saves time. Students can quickly find answers to difficult math problems or grammar questions. Second, AI provides learning resources. For example, some tools explain solutions step by step, helping students understand topics better. Third, AI supports personalized learning. Struggling (挣扎) students can practice repeatedly with AI feedback (反馈), while advanced learners can explore harder tasks. However, there are also some disadvantages. Depending too much on AI can make students lazy and may stop them trying to solve problems independently. It’s not helpful to improve their thinking skills. This can hurt their learning in the long run. Another problem is that AI tools sometimes give wrong answers, especially for open-ended questions like essays. Lastly, using AI can lead to cheating. Copying AI-generated work without learning breaks trust between students and teachers. AI can be a helpful study tool if used wisely. Students should treat it as a guide, not a replacement for their own efforts. Balancing AI assistance with active learning is key to success. 1. What is one advantage of using AI for homework? A. It makes students lazy. B. It saves time. C. It is always exact. D. It replaces teachers. 2. What does the underlined word “personalized” in Paragraph 2 mean? A. Free of service. B. Suitable for each student. C. Very special. D. Custom-made service. 3. What is the result of students becoming overly dependent on AI? A. They might develop better problem-solving skills. B. They might struggle with traditional methods of studying. C. They might reduce their own critical thinking abilities. D. They might become more confident. 4. Why should students use AI wisely? A. To avoid understanding concepts. B. To finish homework without thinking. C. To enjoy its benefits and avoid shortcomings. D. To make AI replace their teachers. 5. What is the best title for this passage? A. The Dangers of AI in Education B. How AI Replaces Teachers C. Why Students Should Never Use AI D. The Pros and Cons of Using AI for Homework 【答案】1. B 2. B 3. C 4. C 5. D 【导语】本文主要讨论了人工智能（AI）在家庭作业中的优缺点，文章指出AI虽然能节省时间、提供学习资源和个性化学习，但过度依赖AI可能导致学生懒惰、思维能力和独立思考能力下降，甚至引发作弊问题，最后强调学生应明智使用AI，平衡AI辅助与主动学习。 1. 细节理解题。根据“AI does bring some advantages for students.

We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about. The list goes on and on. As far as the Internet being a part of our lives—well, that train has left the station. There is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected with high blood pressure（压力） in a young group: teenagers. The study results show that teens who spend at least 14 hours a week online may develop high blood pressure, which makes your heart and blood vessels work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause other diseases. The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 to 17 years old, took part in it. 134 of the teens were described as “heavy Internet users”. And researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first to connect heavy web use with high blood pressure. The lead researcher is Andrea Cassidy Bushrow. She said, “Using the Internet is part of our daily life, but it shouldn’t ruin us.” Ms. Cassidy Bushrow adds that it is important for teens to stop to have a rest regularly（定期地） from their computers or smartphones. She also suggests that parents shouldn’t let their children use the Internet for more than two hours a day, five days a week. 1. What does the underlined part “that train has left the station” mean in paragraph 2? A. The train has changed its course. B. There is something wrong with the station. C. The train has stopped at the wrong station. D. Life without the Internet is nowhere to be found. 2. What is paragraph 3 mainly about? A. The harm of high blood pressure. B. Ways to prevent high blood pressure. C. The advantages of using the Internet. D. The disadvantages of using the Internet. 3. Andrea Cassidy Bushrow would agree that ________. A. teenagers shouldn’t use the Internet B. the Internet will ruin human life in the future C. smartphones are more harmful than computers D. regular breaks are necessary when using the Internet 4. What can be used as the best title of the text? A. Heavy Internet users are mostly teenagers B. How to prevent teenagers from the Internet C. Too much Internet use may be bad for teenagers D. Every coin has two sides - so does the Internet 【答案】1. D 2. A 3. D 4. C 【导语】本文是一篇说明文，主要介绍了互联网已经成为了人们生活的一部分，但是过渡使用网络可能会引发高血压，建议适度使用电脑或手机。 1. 推理判断题。根据“There is no going back to an Internet-free life.”可知，没有人能回到不上网的生活，可推测此处“火车驶离火车站”的含义为“没有互联网的生活无处可寻”。故选D。 2. 段落大意题。根据“... may develop high blood pressure, which makes your heart and blood vessels work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause other diseases.”可知，本段主要讲述患上高血压，会使心脏和血管符合很大，时间久了，会增加你患心脏病发作的风险，且高血压还会引起其他疾病。由此可知，本段主要讲述了高血压的危害。故选A。 3. 细节理解题。根据“Ms. Cassidy Bushrow adds that it is important for teens to stop to have a rest regularly（定期地） from their computers or smartphones.”可知，卡西迪·布什罗女士认为对青少年来说，经常用电脑或智能手机停下来休息是很重要的。故选D。 4. 最佳标题题。根据“But can using the Internet too much be bad for our health?
