九年级上册英语 Unit 5 Power of Ideas单元过关周测题 第一部分 选择题（共40分） 1、 阅读理解,从每小题A、B、C、D四个选项中，选出能回答所提问题或完成所给句子的最佳答案。（共15小题，满分30分） A Paper is one of the greatest inventions in human history. Before paper was invented, people wrote on many different things, such as animal bones, wood, bamboo, and silk. But these materials were either too heavy to carry or too expensive. Then came Cai Lun, a Chinese official in the Eastern Han Dynasty. He found a new way to make paper. He used tree bark, old cloth, and fishing nets. He mixed them with water, boiled them, and then poured the mixture over a bamboo screen. The paper he made was cheap and good for writing. Later, papermaking spread to Korea, Japan, and then to Western countries. This helped knowledge travel faster and made it possible for more people to learn to read. Today, even though we have computers and phones, we still use paper every day—in books, notebooks, newspapers, and many other ways. 1. Before paper was invented, people wrote on ______. A. computers B. phones C. wood and bamboo D. plastic 2. Who improved the way of making paper? A. A Korean official. B. Cai Lun. C. A Japanese artist. D. A Western scientist. 3. What did Cai Lun use to make paper? A. Animal bones and silk. B. Tree bark, old cloth, and fishing nets. C. Bamboo and wood. D. Plastic and metal. 4. What does the underlined word “spread” in Paragraph 3 mean? A. 消失 B. 传播 C. 停止 D. 发明 5. According to the passage, which of the following is TRUE? A. Cai Lun made paper that was very expensive. B. Papermaking only stayed in China. C. We still use paper in our daily lives today. D. People stopped using paper after computers were invented. B The Power of a Simple Idea In 1946, a young engineer named Percy Spencer was working on radar technology. One day, while standing near a radar device, he noticed something unusual—a chocolate bar in his pocket had melted. Most people would have simply cleaned up the mess and moved on. But Spencer had a different thought: “What if this energy could be used to cook food?” This simple question led to the invention of the microwave oven. Spencer experimented with different foods. The first thing he cooked was popcorn, and then he tried an egg—which exploded in his face! After many tests, he created a metal box that used radar waves to heat food quickly and safely. At first, microwave ovens were huge and expensive. They were only used in restaurants and ships. But as technology improved, they became smaller and more affordable. Today, more than 90% of American households have a microwave oven. Spencer’s story shows us that great ideas can come from everyday observations. He didn’t set out to invent a kitchen appliance—he just paid attention to what was happening around him and asked the right questions. The power of ideas lies not in how complicated they are, but in how we develop and apply them to solve problems. 6. What made Percy Spencer think about cooking food with radar energy? A. He was hungry and wanted to cook dinner. B. He noticed his chocolate had melted near a radar device. C. He was asked to create a new kitchen appliance. D. He read about it in a science magazine. 7. What happened when Spencer first tried to cook an egg? A. It cooked perfectly. B. It exploded. C. It didn’t heat at all. D. It became popcorn. 8. The underlined word “observations” in Paragraph 4 is closest in meaning to ______. A. experiments B. questions C. things seen D. mistakes 9. According to the passage, what makes an idea powerful? A. It must be very complex. B. It only comes from great scientists. C. It needs expensive equipment. D. It is developed and used to solve problems. 10. What can we learn from Spencer’s story? A. Inventions always happen by accident. B. Microwave ovens were popular immediately after invention. C. Paying attention to daily life can lead to great ideas. D. Only engineers can make important inventions. C Innovations That Changed the World Throughout history, certain inventions have completely transformed how people live. Here are three of the most influential ideas of all time. The Wheel is believed to have been invented around 3500 BC in Eastern Europe. At first, it was used for making pottery, not for transportation. It took about 300 years for someone to think of putting wheels on carts. This simple invention made it possible to move heavy goods over long distances, leading to trade and the growth of cities. The Printing Press, invented by Johannes Gutenberg around 1440, revolutionized how information was shared. Before the printing press, books were copied by hand, which took months or even years. Gutenberg’s machine could produce hundreds of copies in the same time. This meant knowledge was no longer limited to the rich—ordinary people could read and learn. The Internet, perhaps the most powerful invention of modern times, began as a military project in the 1960s. It was created to connect computers across long distances. Today, it connects billions of people worldwide. Information that once took weeks to travel can now be shared in seconds. The Internet has changed everything from shopping and education to communication and entertainment. These inventions share something in common: each started with a simple idea that someone developed through hard work and persistence. They remind us that great changes often begin with small thoughts. 11. What was the wheel FIRST used for? A. Moving heavy goods. B. Making pottery. C. Building carts. D. Traveling long distances. 12. How did the printing press change society? A. It made books cheaper for rich people only. B. It allowed ordinary people to access knowledge. C. It took less time to copy books by hand. D. It was invented by a Chinese official. 13. When was the Internet first developed? A. In the 1440s. B. In the 1960s. C. In 3500 BC. D. In 1946. 14. What do the three inventions have in common? A. All were invented in Europe. B. All were used for communication. C. All started with simple ideas and hard work. D. All became popular immediately after invention. 15. The passage is mainly about ______. A. how to become an inventor B. the history of transportation C. three inventions that changed the world D. the differences between old and new technology 二、阅读还原（五选五，满分10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。 Turning Ideas into Reality Have you ever had a great idea but didn’t know how to make it happen?

It was popularized by Tony Buzan, a British psychologist, in the 1970s. To create a mind map, start with a central idea in the middle of a page. Draw a circle around it. Then, draw branches from the center for the main topics related to your idea. On each branch, write one keyword or short phrase. From these branches, you can add smaller branches with more details. Mind maps are useful for many things—taking notes, planning projects, studying for exams, and even solving problems. They help you see connections between ideas that you might not notice in a traditional list. One of the biggest advantages of mind maps is that they use both sides of your brain. The left side handles words and logic, while the right side deals with images and creativity. When you combine these, you remember information better and come up with more creative ideas. Many successful thinkers and inventors use mind maps to develop their ideas. Try making one for your next project—you’ll be surprised at how much it helps! 1. Who popularized the mind map? (No more than 2 word ) _____________________________________________________________________________ 2. Where should you put the central idea?

It was first developed by companies like Apple and Samsung in the early 21st century, and since then, it has completely changed the way we live. Smartphones have made our lives much more convenient. We can use them to communicate with friends anytime and anywhere through calls, messages, or video chats. They also allow us to search for information, read news, and learn new things quickly. Besides, we can take photos, listen to music, and even shop online with just a few taps. I think the smartphone shows how powerful ideas can be when they are turned into reality. Creative thinking and hard work can lead to inventions that make a big difference in our daily lives. I hope to become a creative person who can also bring useful ideas to the world. 学科网（北京）股份有限公司 $
