It will remain open during lunch breaks for one week. Every object has a short story about change, invention or service to others. Please handle objects only when a guide says you may. Display One: A Letter and a Phone. Read a copied family letter and watch a short explanation of modern communication. The display asks what has changed and what still matters when people keep in touch. Display Two: An Old Bag with a New Handle. Follow the repair process through three photographs. The owner has used the bag for four years. A small repair has helped it remain useful. Display Three: A Paper Bridge. Compare two shapes and read the testing record. The record includes a failed test and explains what was changed afterward. You may try the separate demonstration model with a guide. Display Four: A Worker's Notebook. Read selected pages shared with permission. They show how a repair worker records problems carefully and checks each job. Before leaving, write a question or comment on a card. The guides will collect them and improve the explanations. The museum is small, but the stories can help us see ordinary things with more attention. 46. When can students visit the museum? A. Every weekend for a year. B. Only before school on January 1. C. During lunch breaks for one week. D. Only at midnight. 47. What question does Display One explore? A. How to buy the cheapest phone. B. Changes and lasting values in communication. C. Which family owns the most letters. D. How to repair a bridge. 48. How long has the old bag been used? A. Four years. B. Twelve years. C. Three months. D. One week. 49. What is included in the bridge record? A. Only the best result. B. A promise that every bridge is perfect. C. A list of private addresses. D. A failed test and a later change. 50. Why are visitors asked to leave comments? A. To replace the guides with machines. B. To choose a new room number. C. To improve the explanations. D. To sell every display object. B Our class wanted to invite someone to talk about hard work. We thought of a famous athlete, but Ms. Lin suggested a person closer to us: the bicycle repairer near the school gate. Mr. He arrived with a small box of worn parts. He showed us a wheel that did not turn smoothly. Instead of changing everything at once, he checked one possible cause after another. He explained that a quick guess could waste a customer's money and useful materials. A student asked whether his work was always interesting. Mr. He said some tasks were repeated many times. Yet each bicycle belonged to a person who needed it. Careful work helped a child get to school or a parent reach a job. He also described a mistake he once made. He admitted it, explained it to the customer and corrected the repair. “Being responsible does not mean pretending you never make a mistake,” he said. After the talk, I looked differently at the small repair shop. Skill, honesty and care were present there every day. I did not need to wait for a famous person to learn about hard work. There was already an example on my way to school. 51. Who did Ms. Lin suggest inviting? A. A famous athlete. B. A foreign tourist. C. A bicycle repairer. D. A television singer. 52. Why did Mr. He check possible causes one by one? A. To avoid wasteful guesses. B. To avoid talking to customers. C. To make every repair take a year. D. To use all new parts every time. 53. What made repeated tasks meaningful to him? A. Customers never asked questions. B. Every task brought a prize. C. Each bicycle served a person's daily needs. D. All bicycles were exactly the same. 54. How did he deal with a past mistake? A. Hid the bicycle. B. Admitted it and corrected the repair. C. Stopped working forever. D. Denied it and blamed the customer. 55. What did the writer realize? A. An ordinary worker can be a valuable example. B. Repeated work can never help people. C. Hard work exists only in famous careers. D. Repair skills have no connection with honesty. C During an exchange activity, our class prepared a game for visitors from another school. We wrote the rules in English and asked one student to read them aloud. The visitors smiled, but when the game began, several did something different from what we expected. At first, we thought they had not listened. Then one visitor asked whether “pass” meant giving the card to another person or skipping a turn. Our rule had used the word without a clear example. The misunderstanding was partly our responsibility. We stopped and demonstrated one full round. We used a short sentence for each step and showed the action. The visitors asked two more questions. After that, the game went smoothly. Later, we revised the written rules. We added numbered steps and pictures. We also asked a younger class to try them without our explanation. Their questions helped us notice another unclear part. The experience changed our idea of communication. Speaking correct sentences is important, but listeners also need enough context. A smile does not always mean complete understanding. Giving an example and inviting questions can be more useful than simply repeating the same words more loudly. 56. What happened when the game first began? A. Some visitors followed the rules differently. B. Nobody came to the activity. C. The visitors refused to smile. D. The cards were all missing. 57. Why was the word “pass” confusing? A. It was printed in a different color. B. It was not an English word. C. It could refer to two different actions. D. It had no possible meaning. 58. What helped the game go smoothly? A. Removing all visitors. B. Repeating the rules more loudly only. C. Making the sentences longer. D. A demonstration and answers to questions. 59. Why did a younger class test the revised rules? A. To find unclear parts without the writers' explanation. B. To choose the most expensive cards. C. To stop the exchange activity. D. To translate every schoolbook. 60. What is the main lesson? A. Examples and context support understanding. B. Questions show that listeners are rude. C. A smile always means agreement. D. Correct grammar alone guarantees understanding. D A school replaced paper notices with a digital screen near the entrance. The change saved some printing, and the screen could be updated quickly. The school called it a step toward greener communication. After a month, students noticed two problems. The screen showed many messages in a fast loop, so some people missed important information. It also stayed on late at night when nobody needed it. A useful idea still needed better daily management. The school asked students and workers for suggestions. They slowed the message changes, used larger words and set a timer to turn the screen off after activities ended. For visitors who could not read the screen comfortably, a staff member remained available to help. The group did not claim that every digital screen was greener than every printed notice. Energy use, equipment life and people's needs all mattered. Sometimes a small paper sign used for a long time could still be a sensible choice. The project showed that “new” and “green” are not automatically the same. We should look at how a tool is used throughout its life. A good decision considers materials, energy and clear communication together, then checks whether the expected benefits actually appear. 61. What was one benefit of the digital screen? A. It never needed care. B. Notices could be updated quickly. C. It made every message easier for everyone immediately. D. It used no energy at any time. 62. What problem appeared after a month? A. The screen could only show pictures. B. Messages changed too quickly and the screen stayed on unnecessarily. C. The school had no messages. D. All printed books disappeared. 63. Why was a timer added? A. To replace staff help. B. To count all visitors' names. C. To turn the screen off after activities. D. To make every message longer. 64. What does the passage say about paper signs? A. They cannot convey useful information. B. A long-used small sign may still be sensible. C. They are always worse than digital screens. D. They must all be replaced at once. 65. What does the writer encourage? A. Treating every new product as green. B. Considering appearance only. C. Ignoring users after buying equipment. D. Checking real benefits across a tool's use. 阅读理解第二节 · E 阅读下面短文，从A—E五个句子中选择正确选项填入空白处，使短文完整、通顺。每个选项只能使用一次。（共5小题；每小题1分，满分5分） Looking back on a term can help you plan the next one.
