But it took years of hard work to make this possible. The invention of the electric light bulb is often credited to Thomas Edison, but the real story is more complex. Before Edison, many scientists had worked on electric lighting. In 1802, Humphry Davy created the first electric light by passing electricity through a material. However, it was too bright and didn't last long. In 1841, Frederick de Moleyns got the first patent for an incandescent light bulb, but it was not practical. Edison began his work on the light bulb in 1878. He tested over 1,600 materials to find a suitable filament (灯丝). Finally, he used carbonized bamboo, which could last for over 1,200 hours. In 1879, Edison's bulb became the first practical and long-lasting electric light. However, a British scientist named Joseph Swan had also invented a similar bulb around the same time. The two men eventually joined their companies and formed Edison-Swan United. The light bulb did not change the world overnight, but it gradually transformed how people lived and worked. It extended the day, made cities safer, and helped factories run at night. Without this invention, our modern world would look very different. 26. Who is often credited with inventing the electric light bulb? A. Humphry Davy. B. Joseph Swan. C. Frederick de Moleyns. D. Thomas Edison. 27. What did Edison test over 1,600 materials for? A. To find a cheap material. B. To find a suitable filament. C. To make the bulb smaller. D. To get a patent. 28. How long could Edison's carbonized bamboo filament last? A. Less than 100 hours. B. About 500 hours. C. Over 1,200 hours. D. More than 2,000 hours. 29. What happened between Edison and Joseph Swan? A. They became enemies. B. They formed a joint company. C. They stopped their research. D. They gave up their patents. 30. Which of the following is NOT mentioned as a benefit of the light bulb? A. It made cities safer. B. It extended the day. C. It helped factories run at night. D. It reduced the cost of electricity. B 阅读下面短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 When people think of inventors, they often imagine scientists in white coats working in labs. But sometimes, great inventions come from ordinary people with a creative idea. One such person is 11-year-old Gitanjali Rao. In 2017, she invented a device called "Tethys" to test for lead (铅) in drinking water. She was inspired by the water crisis in Flint, Michigan. She wanted to find a fast and cheap way to test water. Her device uses carbon nanotubes to detect lead. The result was quick and accurate. For this invention, she was named America's Top Young Scientist. Another example is Sam Houghton. At just three years old, he came up with a tool to pick up leaves more quickly. He saw his father sweeping leaves in the garden. He thought two brooms tied together could cover a larger area. That simple idea became a useful gardening tool. These stories show that age and background don't matter. A creative idea can come from anyone, at any time. The important thing is to keep your eyes open, stay curious, and never stop asking "what if". 31. What did Gitanjali Rao invent? A. A new type of broom. B. A device to test for lead in water. C. A machine to clean water. D. A sensor to detect pollution. 32. What inspired Gitanjali Rao to create her invention? A. A science class. B. A water crisis in Flint, Michigan. C. Her father's work. D. A book about inventors. 33. How does Rao's device work? A. It uses special paper. B. It uses carbon nanotubes. C. It uses a chemical reaction. D. It uses electricity. 34. What idea did Sam Houghton come up with? A. A new way to water plants. B. A tool to pick up leaves faster. C. A machine to cut grass. D. A new type of broom. 35. What is the main message of the passage? A. Inventions are only made by scientists. B. Young people cannot be good inventors. C. Creative ideas can come from anyone. D. Inventions require expensive equipment. 第四部分 七选五（共10分，每小题2分） 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 How to Develop Creative Ideas Creativity is not a talent that only a few people have. 36 ______ Here are some simple ways to help you think more creatively. First, ask questions. Don't accept things as they are. Ask "Why?" and "What if?" 37 ______ For example, if you see a bicycle, you could ask, "What if it could fly?" Second, get out of your comfort zone. Try new activities, read different kinds of books, and talk to people from different backgrounds. 38 ______ Third, keep a notebook. Write down all your ideas, even the silly ones. Sometimes a silly idea can lead to something great. 39 ______ Fourth, take breaks. When you are stuck, step away from your problem. Go for a walk, listen to music, or take a nap. 40 ______ Remember, creativity is like a muscle. The more you use it, the stronger it gets. A. Your brain often works better after a rest. B. It is a skill that can be practiced and improved. C. You should always follow the rules. D. This helps you see things from new perspectives. E. Don't be afraid to make mistakes. F. You might forget it if you don't write it down. G. This encourages you to think beyond the obvious. 第五部分 语法填空（共15分，每小题1.5分） 阅读下面短文，在空白处填入一个适当的词或括号内单词的正确形式。 Most people know that the telephone 41 ______ (invent) by Alexander Graham Bell in 1876.

But how did it begin? In the 1960s, the U.S. government wanted a communication system that could survive a nuclear war. They asked scientists to create a network that would still work even if some parts were destroyed. In 1969, ARPANET, the first version of the Internet, was created. It connected four universities. In the 1980s, the Internet became more widely used. Tim Berners-Lee, a British scientist, invented the World Wide Web in 1989. This made it much easier to share information. He also created the first web browser. Berners-Lee chose not to patent his invention, so anyone could use it for free. Today, the Internet connects billions of people around the world. It has changed how we work, learn, shop, and socialize. It has also created new jobs and industries that never existed before. However, it also brings challenges, such as privacy concerns and the spread of false information. 51. Why did the U.S. government want to create a new communication system in the 1960s? 52. When was ARPANET created and how many universities did it connect? 53. What did Tim Berners-Lee invent in 1989? 54. Why could anyone use Berners-Lee's invention for free? 55. What are two challenges that the Internet has brought? 第七部分 书面表达（共15分） 描述一项发明如何改变了我们的生活。 要求： 1. 写明这项发明是什么； 2.说明它在过去和现在的使用情况； 3.至少使用两个被动语态句子（如：It was invented by... / It is used for...）； 4.词数80词左右；结构清晰，语言正确。 Unit 5 Power of Ideas 单元测试卷 参考与详细解析版答案 第一部分 单词、短语与句子（15分） A) 答案 1. invented 2. creative 3. changed 4. machines 5. invention 解析 1. 句意：托马斯·爱迪生于1879年发明了电灯。描述过去事实，用一般过去时“invented”。 2. 句意：伟大的想法往往来自于创造性的思维和好奇心。“creative”为形容词，修饰“thinking”。 3. 句意：智能手机已经改变了我们的沟通方式。“has + 过去分词”构成现在完成时，“changed”为过去分词。 4. 句意：许多有用的机器，如洗衣机，让生活更便利。复数“machines”泛指多种机器。 5. 句意：莱特兄弟的发明——飞机，永远改变了人类历史。“invention”为可数名词，单数。 B) 答案 6. is used for 7. come up with 8. in the past 9. changed my life 10. think about 解析 6. 句意：互联网被用于很多事情。主语“The Internet”为单数，用“is used for”表被动及用途。 7. 句意：你能想出更好的办法吗？“come up with”后接想法、方案。 8. 句意：爷爷告诉我人们在过去怎么生活。“in the past”作时间状语。 9. 句意：手机完全改变了我的生活。“change one's life”固定搭配，此处用现在完成时“has changed”。 10. 句意：开始前应仔细思考真正需要什么。“think about”表示“考虑”。 C) 答案 11. is used 12. was, invented 13. to improve 14. is, took 15. will be 解析 11. 被动语态“be used for”，主语单数，用“is used”。 12. 一般过去时被动语态“was/were + 过去分词”，主语“invention”为单数，故“was invented”。 13. “how to improve”为“疑问词+不定式”结构，作“discussing”的宾语。 14. “It is said that...”固定句型，“took place”表示“发生”，用一般过去时。 15. 一般将来时被动语态“will be + 过去分词”，故填“will be”。 第二部分 完形填空（15分） 答案 16.

It was invented in the early 1990s, but the first smartphone was very different from today's models. In the past, it was mainly used for making calls and sending text messages. Today, it is used for almost everything — taking photos, watching videos, shopping online, and even controlling our homes. I think the smartphone has greatly changed our lives. It makes communication faster and easier. However, it is also used too much by some people. We should use it wisely and not let it control us. 学科网（北京）股份有限公司 $
