What do you think our life will be like in 50 years or more? To answer this, you can read a sci fi book. Perhaps you will have some ideas then. Today, many young readers are interested in science fiction. _ _ For one thing, science fiction gives us a chance to imagine what our future will be like. Anything is possible. We can dream big. Some people think there will be flying cars and robot servants. Others believe we will learn more about strange aliens and other worlds. Another reason is that sci fi writers and their work can inspire us to create the future. In 1945, a sci fi writer named Arthur C. Clarke wrote about a system of space stations. In the article, he predicted (预测) the earth of the future would have many TV stations and that people would send TV programs around the world. Besides, in a short story by Clarke, he suggested people in the future would use a system to talk with others around the world. Amazingly, the short story was actually the inspiration for the Internet! Science fiction is also popular because it can make us think about our world in new ways. Although many sci fi stories are set in imaginary (虚构的) worlds or societies, they can help us better understand the real world. What will the future be like? Sci fi inspires us and helps us to understand what it could be like in the future. 1. ( ) Why does the writer list the questions in Paragraph 1? A. To show the writer's predictions. B.

Science. 考点6:任务型阅读。 The Future of Transportation: Flying Cars In recent years, the idea of flying cars has moved from science fiction to real life. These cars, often called VTOL aircraft, are designed to combine the advantages of cars and the speed of airplanes. Some technology companies are working hard to develop them, hoping to change the way we travel in cities. Flying cars use new technologies such as electric power, self driving systems and tools to avoid accidents. They can take off and land in small spaces. This makes them perfect for busy cities. Imagine a future where you can avoid traffic by flying from your home to your school or workplace in much less time! However, there are still challenges. Safety is a big problem because flying cars must share the sky with other airplanes and avoid obstacles (障碍物). Laws and rules also need to be developed to control their uses. Besides, the cost of these cars must be lowered so that more people can afford them. Although there are problems to solve, flying cars are good for our lives. For example, they could reduce traffic, lower pollution, and help emergency services reach places faster. They could also change how cities are planned. For example, buildings become taller instead of spreading out. Flying cars are an exciting new idea of travel. As technology improves, the dream of flying cars may soon become a normal part of our lives. 1. What are flying cars like? They combine the advantages of cars and_. 2. What does the underlined word “them” refer to? It refers to _. 3. How many challenges of flying cars are mentioned in the text? _ challenges are mentioned in the text. 4.

Last weekend, I went climbing with some of my friends. When we reached the top of the mountain, a strong wind blew. Then we saw a spaceship coming down from the sky. We felt very surprised and excited. But we saw nothing at that time. In the evening, when we were ready to sleep in the tent, we saw some aliens standing near us. They were tall and strong and their teeth were as sharp as knives. When they saw us, they were frightened, staring at us. We waved our hands to greet them, but they didn't respond to us. And then they walked into their spaceship and flew away. 1 学科网(北京)股份有限公司 $
