Today is June 30. Visitors bring objects, record each visit and learn a repair skill. 阅读“物品护照”时，请区分首次到访、最近维修和持续时长。 Object Passport Log Object First visit Repair visits Latest action Now desk lamp Feb. 12 2 rewired on June 10 in use school backpack Mar. 3 1 zip replaced on Mar. 3 in use wooden chair Apr. 18 2 leg rebuilt on May 6 in use old radio May 28 1 checked; unsafe parts recycled A passport is closed only when an object can no longer be used safely. The old radio, for example, was not repaired for home use. Safe parts were removed, and the rest was recycled correctly. Volunteers do not simply fix things for visitors. They explain what went wrong and teach one skill. A lamp owner learned how to check a loose wire safely without touching it. The chair owner learned why wood should be kept dry. The café sometimes reconditions an object: it repairs, cleans and tests the object so that it can be used again. The prefix re- helps readers guess that the object is returned to a usable condition. Decision Path check safety → repair if possible → test → return to use if unsafe and unrepairable → remove useful parts → recycle the rest 1. Which sentence is correct on June 30? A. The café has been open since January 15. B. The backpack has had two repair visits. C. The radio has been in use since May 28. D. The chair was first repaired in February. 2. What does the underlined word “reconditions” most probably mean? A. Throws away again. B. Makes usable again. C. Sells at a higher price. D. Records for the first time. 3. Which object followed the “unsafe and unrepairable” branch? A. Desk lamp. B. School backpack. C. Wooden chair. D. Old radio. 4. How long has the backpack been in use after its recorded repair? A. Since March 3. B. For March 3. C. Since one visit. D. For June 30. 5. What is special about the café's method? A. It replaces every old object with a new one. B. It teaches owners skills while extending object life. C. It repairs electrical objects without checking safety. D. It recycles objects before trying to repair them. 参考答案与订正 一、默写与重点句翻译 题目 参考答案 / 要点 默写1—30 1—15：prefix; reuse; recycle; renew; retake; revisit; rewrite; rebuild; rethink; repair; period; point; since; for; already。 16—30：think twice; rethink our habits; reuse a plastic bag; recreate a greener world; retake a photo; revisit a place; rewrite the report; rebuild the wall; for five days; since Monday; since three years ago; since I listened to the talk; have kept doing; have learned a lot; a period of time。 翻译1—5 We have reused this paper box for three months. / I have kept sorting waste since I listened to that talk. / She wants to retake the photo because the first one is unclear. / The workers have already rebuilt the wall. / We need to rethink our use of single-use plastics. 二、课本核心任务 题目 参考答案 / 要点 1 rewrite; rebuild; retake 2 visit it again 3 for 4 since 5 for five days 6 since 2024 7 watched 8 We have planted trees for three months. 9 rewrite / rethink 10 示例：I have used a cloth bag for two years. 三、单项选择与语法填空 题目 参考答案 / 要点 单项选择1—10 1.A 2.B 3.B 4.A 5.A 6.B 7.B 8.A 9.B 10.A 语法填空1—10 1. have kept; 2. for; 3. since; 4. repaired; 5. have rewritten; 6. started; 7. yet; 8. rethink; 9. for; 10. to improve 四、看图写话 题目 参考答案 / 要点 1 The boy is rewriting his work carefully. 2 The family is revisiting the park. 3 The workers are rebuilding the damaged wall. 4 The girl retakes the photo because the first one is blurry. 5 The boy has sorted waste for several days. 五、阅读理解 题目 参考答案 / 要点 阅读理解1—5 1.A 2.B 3.D 4.A 5.B Grammar in Use 课时同步练习 · 1 学科网（北京）股份有限公司 $
