(每题2分，共10分) Match each problem with the correct advice. (将每个问题与对应的建议进行匹配。) Problems Advice 32. I love eating snacks like chips and candy. My parents say I eat too much junk food, but I think it's fine. How can I know if I'm eating too much? A. Try creating a "reading corner" in your room. Make it comfortable with good light. Start with just 10 minutes of reading each day. You could ask your friends for book recommendations. Remember, every famous writer started as a reader first. 33. My best friend just got a new smartphone. Now she's always playing games on it and doesn't talk to me much anymore. I miss our old conversations. What should I do? B. Being outside is good for your eyes and your mood. You don't need to do sports if you don't want to. Just sitting in a park, walking around your neighborhood, or lying on the grass can help. Fresh air and sunlight are natural medicines. 34. I want to become a writer when I grow up, but I don't enjoy reading books. My teacher says good writers must read a lot. Reading is so boring to me. Any advice? C. Keep a simple food diary for one week. Write down everything you eat and drink. At the end of the week, look for patterns. How many snacks did you have? How many fruits and vegetables? Compare with health guidelines online. The numbers won't lie. 35. I spend almost 8 hours every day looking at screens — my phone, computer, and TV. My eyes often feel tired and dry. Sometimes I get headaches. What can I do? D. Tell her how you feel in a kind way. Use "I" statements like "I feel sad when we don't talk like we used to."

You could set a timer to remind yourself to take breaks. Every 30 minutes, look away from the screen for 20 seconds at something 20 feet away. Also, remember to blink more often — people blink less when looking at screens. B. 根据短文内容选择最恰当的答案。 (每题2分，共12分) In a small town in Japan, there is a very special library. It has no books. Instead, it lends out "human books" — real people with interesting life stories. The Human Library started in Copenhagen, Denmark, in 2000. The idea was simple: create a safe place where people could "borrow" another person for a 30-minute conversation. The goal was to break down prejudices (偏见) by allowing people to ask questions directly to someone from a different background. Today, Human Libraries have appeared in more than 80 countries. The "books" can be anyone — a refugee (难民), a police officer, a homeless person, a person with a disability, or someone who has survived a serious illness. "Readers" can ask anything they want, as long as they are respectful. Yuki Tanaka, a 15-year-old student from Tokyo, borrowed a "book" named Mr. Suzuki during a school trip. Mr. Suzuki had been a factory worker for 40 years before he lost his job because robots took over his work. "I thought he would be angry about technology," Yuki said. "But instead, he told me that robots do the boring work, so humans can do more creative things. He went back to school at age 60 and learned to design video games! I never expected to hear such a positive story." The Human Library has become popular in schools. Teachers find that it helps students develop empathy (同理心) and communication skills. Instead of reading about the world in textbooks, students get to hear real voices and real experiences. Many students say that talking to a "human book" taught them more than any traditional lesson. However, organizing a Human Library event is not easy. It requires finding volunteers who are willing to share personal stories. It also needs trained librarians to make sure conversations stay respectful. But those who have tried it say the results are worth the effort. "Everyone has a story worth hearing," says the founder of the Human Library. "And sometimes, listening is the most powerful thing you can do." 37. What is special about the Human Library? A. It has a very long history. B. It only lends books to students. C. It lends real people instead of books. D. It only has books about robots. 38. Why was the Human Library started in Copenhagen? A. To help people read more books. B. To help people understand each other better. C. To train more librarians. D. To replace traditional libraries. 39. What did Yuki Tanaka learn from Mr. Suzuki? A. Technology always takes away jobs. B. Robots are better than humans at everything. C. Losing a job can lead to new opportunities. D. Old people cannot learn new skills. 40. The phrase "break down prejudices" in Paragraph 2 most likely means ________. A. create new ideas B. reduce unfair opinions about others C. build stronger walls D. write more books about differences 41. What can we infer (推断) from the last two paragraphs? A. Human Library events are easy to organize. B. The founder regrets starting the Human Library. C. Traditional lessons are more valuable than conversations. D. Even though organizing is difficult, people find it meaningful. 42. Where can we probably read this text? A. In a sports magazine. B. In a school newspaper. C. In a cookbook. D. In a travel guide. 六、完形填空(共12分) Do you know that your brain changes when you learn something new? This ability is called neuroplasticity (神经可塑性). Scientists used to believe that after childhood, the brain stopped changing. But now they know that's not true. The brain can create new pathways at any age. When you practice the piano, solve a math problem, or learn a new language, your brain is 43 working. It builds connections between brain cells. The more you practice, the 44 these connections become. That's why repetition is so important for learning. But here's the exciting part: your brain doesn't just remember what you learn. It actually gets 45 at learning over time. Think of it like going to the gym. The first time you lift weights, it's hard. But after weeks of practice, your muscles get stronger. 46 , after weeks of studying, your brain becomes more efficient at learning. This is why learning a second language is 47 for students. It trains the brain to think in different ways. Studies show that people who speak two or more languages often have better problem-solving skills and memory, even in old age. So don't be afraid of challenges. Every time you struggle with a difficult topic, your brain is growing. That feeling of frustration? That's actually a 48 that your brain is working hard and building new connections. Keep going, and you'll be surprised by what your brain can achieve. 43. A. quietly B. constantly C. suddenly D. lazily 44. A. weaker B. fewer C. stronger D. stranger 45. A. worse B. slower C. faster D. better 46. A. Finally B. Similarly C. Unfortunately D. Differently 47. A. useless B. harmful C. boring D. beneficial 48. A. sign B. joke C. mistake D. secret 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. 49.

They earn one time dollar for each hour of service they do for someone in the community. 51. The regular economy ignores valuable contributions like caring for neighbors or teaching children. 52. It builds stronger communities / It decreases loneliness / It increases trust / It helps neighbors become friends. (Any one) 53. 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.) 54. 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. 书面表达 One possible version: My Dream to Become a Doctor Everyone has a dream. My dream is to become a doctor in the future. First, I have always been interested in biology and how the human body works. Learning about different diseases and treatments excites me. Second, I am a patient and caring person. I enjoy helping others when they feel sick or sad. Being a doctor allows me to use this quality to make a real difference. Third, doctors save lives and reduce people's pain. This social value makes the job truly meaningful. To achieve my dream, I will study hard, especially in science subjects. I also plan to volunteer at a local hospital to gain experience. I know becoming a doctor is a big challenge, but I am ready to put in the effort. One day, I hope to wear that white coat and help those in need. 学科网（北京）股份有限公司 $
