IV. 阅读理解(2 15' = 30') (A) What do you think is the most useful invention of all time? For many people, the answer is the wheel. It is believed to be one of the oldest and most important inventions in human history. But have you ever wondered how the wheel was invented? Historians believe that the wheel was first used around 3500 BC in ancient Mesopotamia (modern-day Iraq). At first, it was not used for transportation. Instead, it was used by potters to make clay pots. The potter's wheel allowed them to create round and balanced pots much more easily than before. It took about 300 years for people to realize that the wheel could also be used for moving things. The first wheeled vehicles were probably simple carts pulled by animals. This invention changed the world completely. Goods could be transported over long distances. Trade developed, and civilizations grew. Over time, the wheel has been improved in many ways. Today, we have wheels on cars, trains, airplanes, and even in machines we use every day. Without the wheel, our modern life would be very different. However, the wheel was not invented everywhere at the same time. Some ancient civilizations, like the Incas in South America, never used the wheel for transportation, even though they had the technology to make them. This shows that invention is not just about having the ability — it is also about having the idea and the imagination to use it. 根据短文内容,选择最佳答案(每小题2分)。 1. What was the wheel first used for? A. For transporting goods. B. For making clay pots. C. For pulling carts. 2. How long did it take for people to use the wheel for transportation? A. About 300 years. B. About 500 years. C. About 1,000 years. 3. What does the example of the Incas show? A. They did not have the technology to make wheels. B. Inventions depend on both ability and imagination. C. The wheel was not a useful invention at that time. 4. What does the underlined word "civilizations" in Paragraph 5 most probably mean? A. Groups of people with their own culture and society. B. Different kinds of machines and tools. C. Natural materials used for making things. 5. What is the author's main purpose in writing this passage? A. To explain how the wheel was invented step by step. B. To show the importance of ideas in invention. C. To compare ancient and modern inventions. (B) Every great invention starts with a simple question: "Is there a better way to do this?" This is the power of ideas — they push us to think, to create, and to improve the world around us. Take the invention of paper, for example. Before paper was invented, people in ancient China wrote on bamboo strips or silk. Bamboo was heavy and difficult to carry, while silk was too expensive for everyday use. People needed a lighter and cheaper material for writing. This need led to one of the most important inventions in history. Cai Lun, a Chinese official, is credited with improving the paper-making process around 105 AD. He used tree bark, old cloth, and fishing nets to create a new kind of paper. This paper was not only cheaper to make but also of better quality. The invention of paper made it much easier for knowledge to spread. Books could be produced more quickly and cheaply, so more people could learn to read and write. However, the story of paper does not end there. Over the centuries, the paper-making technique spread from China to the rest of the world. It traveled along the Silk Road to the Middle East and Europe. Each culture added its own improvements. Today, paper is used everywhere — in books, newspapers, packaging, and countless other ways. What can we learn from this story? First, great inventions often come from practical needs. Second, ideas are not limited by borders — they can travel and grow. And finally, every invention can be improved. The power of ideas never stops; it just keeps moving forward. 根据短文内容,选择最佳答案(每小题2分)。 6. What problem did people have before paper was invented? A. Bamboo was too expensive. B. Silk was too heavy to carry. C. They needed a lighter and cheaper writing material. 7. What materials did Cai Lun use to make paper? A. Bamboo strips and silk. B. Tree bark, old cloth, and fishing nets. C. Wood and stone. 8. How did the invention of paper help spread knowledge? A. It made books more expensive. B. It made books cheaper and more available. C. It stopped people from learning to read. 9. What does the underlined word "practical" in the last paragraph most probably mean? A. Useful and related to real situations. B. Difficult and challenging. C. Old-fashioned and outdated. 10. What is the author's main message in this passage? A. Paper is the most important invention in history. B. Great inventions come from needs and can travel across cultures. C. Only famous inventors can create things that change the world.

The one I find most useful is the mobile phone. The mobile phone was invented in 1973 by Martin Cooper, an American engineer. At that time, it was very large and heavy. But today, mobile phones have become smaller, lighter, and much more powerful. Mobile phones are used for many purposes. We can use them to communicate with others, search for information, take photos, and even study online. They have made our lives much more convenient. For example, we can video call our family members who live far away. In my opinion, the mobile phone is one of the greatest inventions because it connects people and brings the world closer together. Without it, our modern life would be very different. 学科网(北京)股份有限公司 $
