But how does an idea become something that changes the world? The story of the Wright brothers shows us. Orville and Wilbur Wright were two American brothers who loved to watch birds fly. They believed that if birds ___1___ fly, humans could too. The problem of heavier-than-air flight had ___2___ tried by many inventors before them, but none had succeeded. The brothers began working with gliders. They faced two main ___3___. First, how could the glider ___4___ into the air? Second, how could it be controlled once it was flying? For both problems, they found their solution ___5___ studying how birds flew. After the problems were solved, an engine ___6___ to the glider. Then, in December 1903, the world's first plane flights ___7___. The flights lasted only a few seconds, but they proved that powered flight was possible. The invention of the plane has made travel around the world much easier and faster. Journeys that once ___8___ days or weeks can now be completed in ___9___ a few hours. Truly, the Wright brothers' invention ___10___ our world into a much smaller place. 1. B. could 答案： 前半句 birds ___ fly 与后半句 humans could 呼应，主句为过去时 believed → 用过去式 could；can 为现在式不匹配。 2. B. been 答案： had been tried 过去完成时的被动语态。had 后接过去分词，被动需 be 的过去分词 been。句意：飞行问题在他们之前已被许多发明家尝试过。 3. A. challenges 答案： 下文列举了两个具体问题（如何升空、如何控制），对应 challenges"挑战"。 4.

B. was added 答案： engine 为单数主语，与 add 是被动关系"引擎被加装到滑翔机上"；After 从句为过去时 → 用一般过去被动 was added。 7. B. were made 答案： flights（复数）与 make 是被动关系"飞行被完成/实现"；in December 1903 过去时间 → were made。C 选项 are made 时态错。 8. C. took 答案： Journeys that once took days or weeks — take 表"花费时间"，主语为事物；cost 主语为物但指花费金钱；spend 主语为人；paid 主语为人。 9. A. just 答案： can now be completed in just a few hours"现在只需几小时就能完成"；just 表"仅仅"，ever/yet/still 语义不符。 10. A. shaped 答案： shaped our world into a much smaller place"把世界塑造成了更小的地方"；shape v.塑造。produce"生产"、complete"完成"、invent"发明"语义不通。 三、短文填空（共15小题；每小题1分，满分15分） 阅读下面短文，在空白处填入一个适当的单词，或括号内单词的正确形式。 Papermaking — An Invention That Changed the World Can you imagine a world without paper?

They are looking at inventions.) Emma: Look at all these amazing inventions! 1.________________________________ 答案：What do you think is the most useful invention of all time? 根据后文 Wang Han 的回答"I think the radio is..."可知，Emma 在询问对方认为最有用的发明是什么。合理变体：Which invention do you think is the most useful? / What do you think is the greatest invention? 均可。 Wang Han: I think the radio is the most useful invention of all time. Emma: Really? 2.________________________________ 答案：Why do you think so? 后文 Wang Han 用 Because... 解释理由 → Emma 在追问原因。合理变体：Why is that? / What makes you say that? 均可。 Wang Han: Because before the radio was invented, information travelled very slowly. It made the world much smaller. Emma: That makes sense. 3.________________________________ 答案：Who invented it? / Who was it invented by? 后文 Wang Han 回答"It was invented by an Italian called Marconi" → Emma 在问发明者是谁。被动语态问法 Who was it invented by? 也正确。 Wang Han: It was invented by an Italian called Marconi. The first radio message was sent across the Atlantic Ocean in 1901. Emma: Wow, I didn't know that! 4.________________________________ 答案：How else did it change the world? / What other effects did it have? 后文 Wang Han 说"It changed music too" — too 暗示在之前提到的"让世界变小"之外继续补充其他影响 → Emma 在追问更多影响。 Wang Han: Well, it changed music too. People could enjoy music from artists all over the world for the first time. Emma: 5.________________________________ I learned so much from you today! 答案：That's really interesting! / That's amazing! I learned so much from you today 表明 Emma 收获很大 → 前面应为感叹/赞扬。合理变体：Wow, that's so cool! / I never knew that! 注意句末用感叹号或句号均可，问号不行。 Wang Han: My pleasure! Let's go check out some more inventions. 五、阅读理解（共10小题；每小题2分，满分20分） A Did you know that an accident led to one of the most popular inventions in offices today? In 1968, a scientist named Spencer Silver was trying to make a very strong glue. But to his surprise, he produced a glue that was really weak. It could stick things together, but it could be removed very easily. At first, no one could find a use for it — not even Silver himself. Then, in 1974, a man named Arthur Fry had a problem. He sang in a church group and used small pieces of paper to mark songs in his song book. But whenever he stood up to sing, the pieces of paper fell to the floor. He needed something that could keep the paper in place without damaging the pages. Fry remembered Silver's weak glue. He put some of the glue on the back of small pieces of yellow paper. When he tested them, they worked perfectly — the paper stayed in the book, but it could also be removed without leaving any marks. Fry's idea resulted in the production of sticky notes in many sizes and colours. They gradually became popular, and today sticky notes are widely used all over the world. An invention that was started by accident has become something we use every day. The story of sticky notes teaches us an important lesson: sometimes the best ideas come from things that don't work as expected. What seems like a failure at first might turn out to be something great. 答案：1. B 定位第一段："was trying to make a very strong glue" → B。A 为结果而非目标，C、D 未提及。 答案：2. C 定位第一段："It could stick things together, but it could be removed very easily" → C。A 原文未提价格，B 与原文相反，D 原文说可被去除。 答案：3. C 定位第二段："used small pieces of paper to mark songs...whenever he stood up...the pieces of paper fell to the floor" → C。A、B、D 未提及。 答案：4. C 代词指代：them 在"He put some of the glue on the back of small pieces of yellow paper. When he tested them..." → 前句的 small pieces of yellow paper（带胶的小黄纸片）→ C。 答案：5. C 主旨题。最后一段："sometimes the best ideas come from things that don't work as expected" → C。A 太绝对（only），B"always"过于绝对，D 与原文相反。 教师注解 便利贴这篇是课本 p54 Vocabulary in Use 原文改编的。学生读的时候已经见过 Spencer Silver 和 Arthur Fry 的名字，不陌生。讲评时可以带学生回顾课本那页，让他们用被动语态复述一遍便利贴怎么发明的：The glue was invented by accident → It was used by Fry → Sticky notes were produced。既练了阅读又练了语法，一鱼两吃。 B Li Ming is a 15-year-old student from Shijiazhuang. Last month, his school held an "Invention Week" activity. Each student was asked to come up with a creative idea to solve a daily-life problem. Li Ming thought about his grandfather. His grandfather is elderly and sometimes forgets to take his medicine on time. "When my grandfather's medicine bottle was checked last week, I found that he had missed several doses," Li Ming said. So he decided to design a smart medicine bottle. The bottle is made of plastic and has a small button on the top. A mini-timer is connected to the bottle. When it is time to take the medicine, the button lights up and the bottle makes a sound. The sound can be heard from another room. The bottle also records when the medicine was taken, so family members can check whether the medicine has been taken or not. Li Ming's invention was highly praised by his teachers. "It is not the most high-tech invention, but it solves a real problem," one teacher said. "The best inventions are those that make people's lives better." Li Ming's smart medicine bottle is now being tested by several families in his neighbourhood. He hopes that one day it can be produced on a large scale and help elderly people everywhere. "Invention is not just about creating something completely new," Li Ming says. "Sometimes, it's about looking at the world around you and asking: what can I do to help?" 答案：6. B 定位第一段："his school held an 'Invention Week' activity" → B。A、C、D 均未提及。 答案：7. B 定位第二段："sometimes forgets to take his medicine on time" → B。A 未提睡不着，C 未提没瓶子，D 未提不喜欢医院。 答案：8. C 定位第三段第一句："The bottle is made of plastic" → C。Wood/glass/metal 均未出现。 答案：9. B 定位第三段："When it is time to take the medicine, the button lights up and the bottle makes a sound" → B。发送消息/自动打开/叫家人均未提及。 答案：10. C 定位最后一段李明原话："looking at the world around you and asking: what can I do to help?" → C。A 说完全新创造，与原文 not just about creating something completely new 矛盾。B 最先进技术未提。D 赢得比赛未提。 教师注解 B篇是原创的，但结构参考了课本 p54-p55 便利贴和飞机的阅读模式：一个具体人物→发现问题→创造发明→解决了什么→发明带来的意义。讲完可以让种子选手拿这个框架写一段自己的"发明"——用上至少三处被动语态。 第 页 学科网（北京）股份有限公司 $ Power of Ideas · 单元综合练习 人教版2024 九年级上册 · 学生版 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 一、词语运用（共10小题；每小题1分，满分10分） 根据句意及所给提示，在空白处填入适当的单词或单词的正确形式。 ★ 1.
