Many of your finest scientists have discovered that there is life tens of millions of miles away—here, on the beautiful planet Venus. Congratulations! However, we have a polite request: Please stay away. We’re serious. No spacecrafts to Venus, no tasks, no visits. If we wake up one morning and see so many people wandering around in spacesuits, we’re going to be really upset. We don’t want to be impolite. It’s just that we’re shocked by what you’ve done on Earth. Earth looks like a mess. You’ve got health problems, environmental pollution, traffic jams, political fights, etc. No wonder so many of you want to leave Earth for another planet. We know you’d like to come here. That’s what frightens us. You’d all move to Venus at once. If we start having you all up here, pretty soon, the Martians (火星人) and Jupiterians (木星人) are going to come, too. But we can’t handle so much. Venus is not another Earth. You had better _________ because ___________________________. God bless you! Sincerely, Venusians 1.

Today I am very glad to be here to give a speech on saving the Earth. Our Earth used to be healthy and beautiful. However, it is facing a lot of serious problems now. The number of wild animals is getting smaller and smaller. What’s worse, there are more and more natural disasters than before, such as floods and sandstorms. Both people and animals are in great danger now. Why does this happen? Firstly, people cut down too many forests. As a result, a lot of wild animals have nowhere to live or nothing to eat. Besides, more and more smoke and waste cause a great deal of pollution and climate change. Therefore, natural disasters happen more often than before.

Today, a large number of human-made objects (物体) are moving around our planet. Some of these objects are of no use, and then they become space junk. Space junk goes very fast—about 17,000 miles an hour! If a piece of space junk hits (撞击) objects like the International Space Station or working satellites, it can be dangerous. And orbits are getting more crowded because of space junk. Orbits are like busy roads. If a car stops working on Earth’s roads, a tow truck (拖车) takes it away. But in space, there is no such thing that can clean up the junk. So the orbits are becoming more difficult to get into. Luckily, scientists are working on ideas that might one day help clean up space junk. Here are two interesting ones: ▲ . This idea is to send a rocket into space. The rocket can give off water. The water would become a wall to hit the junk and make it slow down or fall out of orbit. Satellite Helper A satellite called Clear Space-1 would find and catch space junk. Once full, the satellite would crash (坠毁) back to Earth and burn up in Earth’s atmosphere (大气层). However, some ideas are not friendly to Earth’s environment. Maybe we need to think about more ways to keep space clean without polluting our own planet. ( )1. ______can be space junk. A. A useless space station B. A broken car C. A working satellite D. A new spaceship ( )2. We must clean up space junk because ______. ① it moves so fast that it may hit space stations ② it makes the orbits crowded and more difficult to get into ③ it may fall out of orbit and hit the Earth ④ it can make the space look dirty A. ①② B. ②③ C. ①③ D. ①④ ( )3.

A. hitting space junk B. catching space junk C. slowing down space junk D. pushing space junk to the moon ( )5. The writer writes the passage to ______. A. guide people to play a part in saving the satellite B. stop scientists from sending satellites into space C. ask people to take the problems of space junk seriously D. tell people how to make satellites 参考答案 Part1 基础提优练 1.1. million 2. millions 2.1. actor 2. action 3. acting 3.1. effects 2. affects 3. effect 4.1. address 2. addressed 5.1. influenced 2. impact 6.1. died 2. death 3. dead 7.1. with 2. on 3. that 4. to make Part2 综合提优练 AAABC ( 1 ) 学科网（北京）股份有限公司 $$ Lesson3 The green miracle Part1 语法提优练 用括号内所给单词的适当形式填空 1.

However, about 35% of natural wetlands have been lost in the past 50 years, said the UN. Hoping to do their part in wetland protection, Lyu Haoyan and Cui Luoyao, two girls from Beijing made a mudskipper amphibious robot (弹涂鱼两栖机器人). They won the Gold Award of the 19th Soong Ching Ling Award for Children’s Invention on Aug 17, 2024. “We wanted to make a simple robot to help collect data (数据), but traditional robots faced problems in wetlands,” Cui told Teens. As an amphibious fish, mudskippers are small and can move freely in wetlands. Inspired (启发) by the little creature, they added a special chest and tail fin to their robot. The fin can help the robot move freely on land and swim underwater. They also learned coding (编程) to control the robot on their phones from far away, up to 300 meters. What’s more, they put in different sensors (传感器) to see plants and check water cleanness. But things didn’t always go well. How to keep the main electronics (电子元件) dry when the robot went underwater was a big problem during testing. “The 3D-printed parts we used couldn’t seal (密封) well,” Lyu told Teens. After trying different methods, they found that placing rubber (橡胶) rings in the gaps (缝隙) worked well to stop water from getting in. After successfully controlling their robotic mudskipper on land and underwater, they were happy with their success. “I feel so proud because our robot can help look into the places that people cannot reach,” said Cui. ( )1. Why did Cui Luoyao and Lyu Haoyan made the robot? A. To protect wetlands. B. To finish their schoolwork. C. To deal with water pollution (污染). D. To learn more about amphibious fish. ( )2. What does “the little creature” in Paragraph 4 refer to? A. Mudskippers. B. The inventors. C. The robot fish. D. Wetlands. ( )3. What would be the best title f or the passage? A. The Importance of Wetlands. B. How Sensors Help in Wetlands. C. Difficulties in Studying Wetlands. D. Students Build Robot to Save Wetlands 二、补全对话 A: Andy, I sent you a WeChat message half an hour ago, but you didn’t reply. B: I’m sorry. I didn’t see it.
