Take the intelligent safety helmet as an example. It is not just a common helmet for protecting heads anymore. This new type of helmet has many special functions. First, it has a built-in GPS locator. If a worker gets lost in a large construction site, managers can quickly find his position through a computer. Second, it has a voice communication system. Workers can talk directly with each other without holding a walkie-talkie. Third, there is a small camera on the front of the helmet. When a worker finds a problem with the machine, he can take photos or record videos immediately and send them to the technical team. What’s more, the helmet can even sense dangerous gases. If the gas concentration is too high, it will give an alarm at once to keep the worker safe. Mr. Li, a construction worker with 10 years of experience, said, “The intelligent safety helmet has become my ‘work partner’. It makes my work easier and safer. I used to carry a lot of tools like a walkie-talkie and a gas detector. Now I just need this one helmet.” Invention and innovation are not only for scientists. They are around us and help people work better. 16.What is the main idea of Paragraph 2? A. The price of the intelligent safety helmet B. The functions of the intelligent safety helmet C. The material of the intelligent safety helmet D. The history of the intelligent safety helmet 17.Which function can help managers find workers quickly? A. The built-in GPS locator B. The voice communication system C. The small front camera D. The dangerous gas sensor 18.What does the underlined word “concentration” mean in Chinese? A. 体积B. 浓度C. 重量D. 温度 19.Why does Mr. Li say the helmet is his “work partner”? ]A. It can talk with Mr. Li like a person B. It replaces many tools he used to carry C. It was given by his workmates D. It has a special shape 20.What can we learn from the passage? A. The intelligent helmet is only for scientists B. The intelligent helmet has four special functions C. Mr. Li has worked as a construction worker for 10 years D. The helmet can’t send photos to the technical team B Innovation doesn’t always mean creating something completely new. Sometimes, improving an existing product to meet people’s needs better is also a kind of innovation. The foldable electric scooter for delivery workers is a good example. Before, most delivery workers used common electric scooters. But there was a big problem: the scooters were too big to store. When delivery workers finished their work, they had to find a large space to park the scooter, which was very inconvenient. Also, the common scooters didn’t have enough battery power for a whole day’s work. Workers often had to stop to charge the battery, which delayed their delivery time. To solve these problems, engineers made some changes to the common electric scooter. First, they made it foldable. After folding, the scooter becomes small enough to put in the trunk of a car or even under a desk. Second, they increased the battery capacity. Now the scooter can run for more than 80 kilometers on a single charge, which is enough for a day’s work. Third, they added a small storage box on the front. Delivery workers can put water bottles, phone chargers and other small things in it. Wang Hua, a food delivery worker, shared his feeling: “The foldable scooter is really great! I don’t have to worry about parking anymore. And its battery lasts all day. It helps me finish my work faster.” This kind of innovation is practical. It comes from understanding people’s real needs and solving their problems. 21.What is the passage mainly about? A. How to make an electric scooter B. A practical innovation for delivery workers C. The history of electric scooters D. Why delivery workers need scooters 22.What was the problem of common electric scooters? A. They were too expensive B. They were too small to carry things C. They were hard to store and had weak battery D. They were not fast enough 23.What does the underlined word “capacity” mean in Chinese? A. 容量B. 重量C. 长度D. 宽度 24.Which of the following is NOT an improvement of the foldable scooter? A. It is foldable B. It has a larger battery C. It has a storage box D. It is cheaper than before 25.What can we infer from the passage? A. Innovation must be something completely new B. The foldable scooter can run 80 kilometers per hour C. Wang Hua is satisfied with the foldable scooter D. Engineers made the scooter for scientists 三、补全对话（共5小题，每小题2分，共10分） 根据对话内容，用恰当的词补全对话。 Teacher: Good morning, class.

They can solve our little troubles easily. The one I use every day is the portable mini USB fan. I am a vocational school student. In summer, my classroom is very hot, especially in the afternoon. The big electric fan in the classroom is not close to my seat, so I always feel hot and can’t focus on classes or skill practice. My dad bought me a portable mini USB fan. It is small, just like my palm. I can put it in my pencil case. It can be charged with a phone charger, and it works for a long time. When I feel hot, I turn it on and put it on my desk. The wind is cool and soft. This small fan solves my big problem in summer. Now I don’t feel hot in class anymore. I can listen to the teacher carefully and practice my skills better. After class, I can take it to the playground too. It’s light and easy to carry. I think good small inventions are all about solving real problems. This mini USB fan is simple, but it helps me a lot. It lets me know that innovation is around us and makes life better. 原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
