三、阅读理解
  Scientists in Britain and the United States have made a new kind of enzyme (酵素) that eats plastics (塑料). 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.
( )11.According to the scientists, the enzyme may solve the problem of     pollution.
A.air B.water
C.light D.plastic
( )12.The underlined phrase “break down” in the passage probably means “    ” in Chinese.
A.实验 B.生产
C.发明 D.分解
( )13.Researchers discovered that a natural enzyme helped eat plastics     .
A.in Britain B.in the US
C.in Japan D.in China
( )14.Which of the following is TRUE according to the passage
A.The scientists are still 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.

  【文章大意】本文是一篇科普短文,普及了环保常识。文章主要介绍了一种可以降解塑料的酵素,对人体、动物和环境无害,可以广泛应用于解决塑料污染问题。
11.D 解析:细节理解题。根据第一段最后一句中的“it could solve the problem of plastic pollution”可知,答案选D。
12.D 解析:词义猜测题。break down后面的宾语为PET,由其后的a form of plastic可知,PET 是一种塑料。第一段末尾提到酵素(enzyme)可以解决塑料污染,故可推知,分解塑料才能解决塑料污染。故选D。
13.C 解析:细节理解题。根据第三段第一句“The researchers made the discovery (发现) while examining the structure of a natural enzyme in Japan.”可知,研究人员在日本检测一种天然酵素的结构时有了这个发现。故选C。
14.A 解析:细节理解题。根据第四段第三句“And we are trying to make more improvements to it.”可知,A选项正确;第四段第四句“The enzyme is not harmful to humans or animals, and it is friendly to the environment.”可知,B、D两项均错误;第四段第二句“It's better than the natural one.”可知,C 选项与文章意思相反。Unit 8 Comic strip & Welcome to the unit

四、完形填空
It's important to learn how to protect the environment. Here are 3R rules for us.
Reduce means “use  16 ”. Don't waste things. If you want to reduce waste, you should use things  17 . A large number of trees are  18  to make paper every year. If everyone uses paper  19  and throws it out, more trees will be cut down. Before we buy something new, think whether it is really necessary.
Reuse means “use again”. Using things as long as possible. When we buy things, make sure  20  they can be used for a long time. Don't use a paper cup or a paper bag. It's  21  to use a china cup or a lunch box, because you can use them again.
Recycle means “change one thing into  22 ”. Although it  23  energy to change something into something else, it's better than throwing it away or burning it. Bottles, cans and paper can easily be  24 .  25  doing these things we can save lots of time and money.

11.In 12.But 13.or 14.of 15.a
【文章大意】短文介绍了保护环境的三种方式,即“减少使用”“重复使用”“再循环”。
16.A 解析:根据reduce“减少”可判断use后接的副词为“更少”。few不可以用作副词。
17.C 解析:如果你想减少浪费,就应当明智地使用物品。
18.B 解析:根据下文“more trees will be cut down”可知,此处指砍伐树木。
19.D 解析:首先根据动词短语uses paper可知,此处应该用副词修饰,再根据“more trees will be cut down”和常识可知,不细心用纸而去浪费的结果是更多的树木被伐去做纸。
20.C 解析:make sure后常接that 引导的宾语从句。
21.A 解析:结合reuse可知,使用瓷杯和饭盒比用纸杯更好。
22.B 解析:else常置于不定代词之后,other常置于它所修饰的名词之前,所以排除C、D选项。该句为肯定句,故用something。
23.A 解析:固定句型:It takes sb....to do sth.。
24.C 解析:根据这一段的首个单词“recycle”可知答案。
25.D 解析:“通过做某事”用“by doing sth.”表示。Unit 8 Revision
