Each of them was taking lessons: Joe with a famous art teacher, and Delia with a great pianist from Germany. Their teachers were the very best, so lessons were expensive, more than they could really afford, but... when you love your art, nothing is too much. But soon the money began to run out, and they couldn't afford the lessons any more. Then one day Delia came back home and told Joe that she had met a man whose daughter, Sally, wanted to learn the piano, and he was going to pay her $50 an hour. "Delia," Joe said, "I'll be much happier if you keep up your lessons." Delia said it didn't matter. "When I've had some money, I'll continue." But Joe also decided to stop his lessons, to draw pictures and sell them. A few days later, Joe came home and proudly took $200 from his pocket. "I met a man from Vermont," he said, "who bought one of my pictures. And he wants to buy more!" . They didn't have to worry any more about money. Then, one day, Joe came home and saw that Delia's hand was wrapped in a bandage (绷带). He asked her what had happened. "Oh," said Delia. "My student, Sally, asked me to make some coffee for her. I dropped the coffee and burned my hand. Sally went straight to the drugstore and got this bandage for me." "Delia, what have you been doing the last two weeks?" Joe asked. She tried not to tell him, but the tears came. "Oh Joe, I couldn't get any students, so I worked as a waitress in a restaurant. Today, I burned my hand with hot water. So I can't work any more. But we'll still have money from the man in Vermont, won't we?" Joe looked at her. "There's no man in Vermont," he said. "I've been working in a drugstore, and today someone came in to buy bandages for a woman whose hand was burned. So when I saw you, well, I guessed." They both laughed. 1. What was Delia's plan when she and her husband couldn't afford their lessons? A. She gave up her lessons. B. She wanted to be a tutor (家庭教师) to earn money. C. She changed her dream. D.

Recently, a research team from the Lanzhou Institute of Chemical Physics at the Chinese Academy of Sciences has created 3D printed organs, including the brain, lungs and intestines. They used hydrogel (水凝胶), a soft material, as the "ink" for printing. People found it hard to print the complex structures inside human organs before. It's also hard to control the organs' hardness. But the team has made breakthroughs in these two aspects. The printed organs are very close to real organs. Human organs have different textures (质地), with our brains being the softest. The team added special elements to the hydrogel to create different textures for each organ. They also printed tiny holes and channels inside the organs. This will help medical students learn better. Scientists also hope 3D printed organs can be used in organ transplants. Hydrogel cannot be used to do that because the human body will fight against it. But scientists are looking for other materials that can grow inside the human body. The first and only successful 3D printed organ used for transplant is a bladder, as the bladder is one of human's simplest organs. Experts expect that this technology will help more patients within a decade. 1. Hydrogel is compared to the "____" for 3D printed organs. A. ink B. printer C. paper D. process 2. How did the research team make the printed organs close to real ones? ① By creating a new type of hydrogel. ② By adding elements to control the organs' textures. ③ By adding details after the organs are printed. ④ By printing the detailed structure of the organs. A. ①② B. ②④ C. ①③ D. ②③④ 3. What is the future direction for the research team? A. To make 3D printed organs that can grow in the human body. B. To find out which organs are as simple as the bladder. C. To grow new organs from old organs. D. To print organs that are as detailed as possible. (C) A Friend Who Changed Me When I entered Grade 8, I was a shy girl who rarely spoke in class. I was afraid of making mistakes and being laughed at, so I always kept to myself. That changed when I met my deskmate, Lucy. Lucy was an outgoing and kind-hearted girl. She noticed my shyness and never forced me to talk, but she always included me in group activities. One day, our teacher asked us to prepare a group speech. My group members were worried because I refused to speak. Lucy pulled me aside and said gently, "I know you're nervous, but your ideas are great. Let's practice together, and I'll stand next to you the whole time." With her encouragement, I agreed to try. We practiced every afternoon after school. Lucy helped me correct my pronunciation and gave me confidence. On the day of the speech, I stood on the stage with Lucy beside me. When I finished, the class cheered loudly. That experience made me realize that I was capable of more than I thought. Now, I am no longer the shy girl I used to be. I actively participate in class discussions and make many friends. I owe it all to Lucy - her kindness and patience helped me step out of my comfort zone. 1. Why did the writer keep to herself in Grade 8? A. She disliked her classmates. B. She was afraid of making mistakes. C. She had no interesting ideas. D. She hated group activities. 2. How did Lucy help the writer with the group speech? A. She forced the writer to practice every day. B. She corrected the writer's mistakes alone. C. She practiced with the writer and encouraged her. D. She gave the writer all the speech content. 3. What can we learn from the passage? A. Shyness is a terrible personality. B. Good friends can help us grow. C. Group speeches are easy to prepare. D. Teachers should encourage students more. (D) The Importance of Reading In the age of smartphones and short videos, many teenagers spend most of their free time on digital devices. They rarely pick up a book, thinking that reading is boring or useless. However, reading is one of the most valuable activities we can do. Firstly, reading improves our language skills. When we read, we meet new words and sentence structures, which helps us write better and express ourselves more clearly. A study shows that students who read regularly score higher in English exams than those who don't. Secondly, reading broadens our horizons. Books take us to different places, times and cultures without us leaving our homes. We can learn about ancient civilizations, space exploration or different ways of life through reading. This helps us understand the world better and become more open-minded. Thirdly, reading reduces stress. Reading a good book allows us to escape from the pressure of daily life and relax our minds. It is a peaceful activity that calms our nerves and makes us feel more relaxed. So, don't let digital devices take over your free time. Pick up a book today - it could be a novel, a biography or a science book. You will not only gain knowledge but also become a better person. 1. Why do many teenagers rarely read books? A. They have no time to read. B. They think reading is boring. C. They can't find good books. D. Their parents don't allow them to read. 2. Which benefit of reading is NOT mentioned in the passage? A. Improving language skills. B. Broadening horizons. C. Making more friends. D. Reducing stress. 3. What does the underlined phrase "broadens our horizons" mean? A. Makes us more intelligent. B. Helps us see more of the world. C. Makes us more confident. D. Helps us relax better. 4. What is the writer's purpose in writing this passage? A. To encourage teenagers to read more. B. To introduce different types of books. C. To criticize teenagers for using smartphones. D. To show the results of a study on reading. 第Ⅱ卷 (非选择题共55分) 综合攻坚·能力跃升 考查语言综合运用 四、词汇（共 10 小题；每小题 1 分，满分 10 分） （A）根据括号中所给的汉语写出单词，使短文意思完整正确。 1. It is very ______ (便利的) for us to study online anytime. 2.

However, a simple “thank you” can have a powerful impact. A recent study found that people who regularly express thanks are not only happier themselves but also make those around them feel valued and appreciated. Take Mr. Johnson, a school bus driver, for example. Every morning, he greets each student with a warm smile. Most students just walk past silently, but one girl, Lily, always says, “Good morning, Mr. Johnson! Have a nice day!” This small act of kindness brightens his entire day. He once said, “Lily’s words remind me that my job matters.” Similarly, at home, saying “thank you” to your parents for cooking dinner or helping with homework can strengthen your relationship. It doesn’t take much time, but it shows respect and care. So, don’t underestimate the power of gratitude. Start today: thank your teacher for their hard work, your friend for their support, or even a stranger who holds the door open for you. You might just make someone’s day—and your own. 1. What is the main idea of the passage? 2. How does Lily make Mr. Johnson feel? 3. According to the passage, what are two benefits of expressing thanks? 4. Where can we show our gratitude besides at school? 5. What does the writer suggest we do at the end of the passage? 七、首字母填空（共10分，每小题1分） Many people travel to different places in the world by air. Usually it takes passengers a long time, perhaps half a day, to stay on the plane. So airlines o____ (1) passengers food. But it is common that they feel bad about food taste. Do you agree? To solve this problem, airlines try hard to i____ (2) their food. They would like to do so because they don't want to lose c____ (3). However, according to scientific research, part of the reason why plane food tastes bad is that at a high altitude (海拔，高度) we cannot taste things as well as we do on the g____ (4). Also scientists have found that our noses become very dry even b____ (5) a plane takes off. As the plane moves up, the change in air pressure (气压) reduces one third of the sensitivity (敏感性) of our taste buds (味蕾). So our taste buds become senseless. The sad fact, however, is that our noses don't know it. All of these help explain why food on the plane tastes so bad. They a____ (6) help explain why airlines choose to offer passengers salty and spicy (辛辣的) food. W____ (7) doing so, the food would be tasteless. Now there are many studies on this. According to one of them, some volunteers are asked to lie with their feet higher than their heads for weeks. And scientists write down their f____ (8) about food taste. Though scientists try t____ (9) best, it is not as easy as they thought. Because they can't deal with the special environment successfully, such as the change in air pressure, making food taste g____ (10) is still hard for them. 八、书面表达（共15分） A Person Who Has Influenced Me Most 在你的成长过程中，一定有人对你产生了深远的影响。他/她可能是你的家人、老师、朋友，甚至是一位你并不认识的公众人物。 请以 “A Person Who Has Influenced Me Most” 为题，写一篇不少于90词的英语短文。 内容需包括： 这个人是谁以及他/她的身份； 他/她做了什么事或有什么品质影响了你； 他/她对你的学习、生活或价值观产生了怎样的积极影响； 你从他/她身上学到了什么。 注意： 文中不得出现真实姓名、校名等个人信息。 答案和解析 一、单项选择 1. 答案：C 解析：look into 意为 “调查”，符合警方调查谋杀案的语境；look for 寻找；find out 查明（结果）；think about 考虑。 2. 答案：D 解析：evidence 意为 “证据”，答句中 “指纹” 是证明偷窃的证据；pride 骄傲；courage 勇气；doubt 怀疑。 3. 答案：B 解析：先行词 the man 指人，且在定语从句中作主语，关系代词用 who；which 指物；whom 作宾语；whose 作定语。 4. 答案：A 解析：refuse to do sth. 是固定搭配，意为 “拒绝做某事”。 5. 答案：A 解析：safety 意为 “安全”，孩子失踪，父母担心其安全；wealth 财富；success 成功；victory 胜利。 6. 答案：D 解析：insist 后接宾语从句，“做错事” 发生在 insisted（过去式）之前，用过去完成时 had done。 7. 答案：B 解析：be guilty of 是固定短语，意为 “犯有…… 罪”。 8. 答案：C 解析：search 后接地点，意为 “搜查某地”；search for 后接人 / 物，意为 “寻找人 / 物”；look through 浏览；look for 寻找。 9. 答案：A 解析：be charged with 是固定短语，意为 “被指控犯有…… 罪”。 10. 答案：A 解析：connect 意为 “联系；关联”，侦探尽力串联线索找到罪犯；collect 收集；consider 考虑；control 控制。 二、完形填空 1.

Firstly, he always encourages me to face challenges bravely. When I struggled with grammar and vocabulary, he stayed after class to explain difficult points patiently. His clear examples helped me improve my grades from 60 to 90 in one semester. Moreover, his positive attitude changed my view on life. Once, I failed a math test and felt discouraged. Mr. Li said, “Failure is just a step closer to success.” His words reminded me to stay confident and keep trying. What’s more, he taught me the importance of kindness. He often volunteers to help underprivileged students, showing that small acts can make a big difference. Inspired by him, I now donate old books to rural schools every month. Finally, I learned from Mr. Li that persistence and optimism are keys to success. He is not just a teacher but a role model who has shaped my values and made me a better person. 学科网（北京）股份有限公司 $
