With its help, plastics can be turned into smaller parts and go away quickly. Scientists believe that, in the future, it could solve the problem of plastic pollution.The enzyme is able to break down PET, a form of plastic. PET was first made in the 1940s and is now widely used to make plastic bottles. It can remain in the environment for many years and pollute large areas of land and water. So it has always been a headache to deal with the waste from PET and other plastics.The researchers made the discovery (发现) while examining the structure of a natural enzyme in Japan. They found that the natural enzyme was helping to break down PET plastics. So, they decided to make small changes to the enzyme by adding some amino acids (氨基酸). It made the natural enzyme's plastic-eating abilities work faster and better.John McGeehan, one of the lead researchers, said, “We've made an improved enzyme. It's better than the natural one. And we are trying to make more improvements to it.” He went on,“The enzyme is not harmful to humans or animals, and it is friendly to the environment. So we are considering putting it into wider use.”The team is now trying to make the enzyme break down PET in large quantities (大量地). “We'll see that the plastic pollution may be stopped with this technology. However, there is still a long way to go,” John McGeehan added.1. According to the scientists, the enzyme may solve the problem of ______ pollution.A. airB. waterC. lightD. plastic2. The underlined phrase “break down” in paragraph 2 means“______” in Chinese.A.实验B.生产C.发明D.分解3. Researchers discovered that a natural enzyme in ______ helped eat plastics.A. BritainB. the USC. JapanD. China4. Which of the following is true according to the passage?A. The scientists are sill trying to improve the enzyme.B. The enzyme will pollute large areas of land and water.C. The natural enzyme works better than the improved one.D. The natural enzyme is harmful to humans and animals.BMany people know that rubbish is a big problem on our our Earth. What many people don I know is that junk (垃圾) has become a problem in outer space tooAccording to BBC News, there are more than 22 000 pieces of space junk floating around the Earth. And these are just the things that we can see from the surface of the Earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.Objects, like bits of old space rockets or satellites. move around the Earth at very high speed, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship. it could damage the vehicle. To make things worse, when two objects in space crash, they break into many small pieces. For example, when a US satellite hit an old Russian rocket in 2009, it broke into more than 2 000 pieces increasing the amount of space junk.To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the Earth's atmosphere (大气) after that time. In the upper parts of the atmosphere, it will bur up.Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net. The net can catch the junk and then pull it into the Earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to the Earth to be safely destroyed.“The problem is becoming more challenging because we re sending more objects into space to help people use their mobile phones and computers,” says Marco Castronuovo, an Italian space researcher. “The time to act is now. The longer we leave the problem, the bigger it will become,” he says.1. What does the underlined word“"these" in paragraph 2 refer to?A. Pieces of space junk.B. Satellites.C. Telescopes.D. BBC news reports.2. Why is space junk considered a problem?A. It burns up after it enters the atmosphere again.B. It often stops the view of telescopes on the Earth.C. It could make new space tools travel at slower speed.D. It may crash into other space tools causing damage and more space junk.3. Future space tools must be able to fall into the Earth's atmosphere so that ______ .A. the tools can be reused laterB. the tools don't become space junkC. the Earth's atmosphere can stay cleanD. the effects of space flight can be studied4. How do the Germans plan to deal with space junk?A. Catch it with nets.B. Use robots to collect it.C. Burn it in the Earth's atmosphere.D. Send it further away from the Earth.5. In which part of the newspaper would you probably read this article?A. Space.B. Local News.C. Education.D. Fashion.四、根据句意和汉语释义写出单词1. The park has taken some ________ (措施) 10 limit the number of visitors.2. ________ (石油) and gas are unrenewable natural resources.3. The two workers ________ (挖)a big hole in the garden yesterday.4.
