Having enough water isn’t our only problem.We also need it to be clean.
Right now, ships and factories are putting wastes into seas, rivers and so on. Even chemicals that farmers use are running into rivers and lakes. All the pollution can make the water dangerous to drink. It can also harm fish and other water-living lives.
We must do something to stop pollution. It’s the best way to protect our world’s most valuable natural resources(资源).

Ⅷ.阅读理解
Scientists in Britain and the United States have made a new kind of enzyme(酶) 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 in 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 the technology. However, there is still a long way to go,” John McGeehan added.
36.According to the scientists, the enzyme may solve the problem of　　　 pollution.
A.air　　　 B.water　　　 C.light　　　 D.plastic
37.The underlined phrase “break down” in the passage probably means “　　　” in Chinese.
A.实验　　　B.生产　　　 C.发明　　　D.分解
38.Researchers discovered that a natural enzyme helped break down plastics　　　.
A.in Britain　　　 B.in the US
C.in Japan　　　 D.in China
39.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.
40.Where may you read this passage
A.In a cooking book.
B.In a science magazine.
C.In a guidebook.
D.In a storybook.
Ⅸ.任务型阅读
　　As we know, all living things have to eat food. For a man, a tiger, a fish, a bird, or even a worm, food is necessary. Generally speaking, all living things are sure to die without food. In every part of the world, many different kinds of animals share living places and live in communities (群落) together. They are connected in the food chain.
Within the food chain, some living things are producers and some are consumers(消费者). Plants are producers because they use sunlight, soil and other things to make their own food. Animals are consumers because they have to eat other animals or plants.
There are four different kinds of consumers in the animal kingdom. A carnivore is an animal that only eats other animals. A herbivore is an animal that only eats plants. An omnivore is an animal that eats both plants and animals. A scavenger is an animal that eats dead animals.
Look at the picture. It is an example of the food chain. The food chain shows the order in which animals eat each other in a community. In the picture, you can see what animal or plant is food for another animal. A leaf is food for a grasshopper, which then becomes food for a hungry mouse. The mouse is food for a snake. The snake is eaten by an eagle. In this way, all of these animals are connected.
根据上文内容判断正(T)误(F)。
41.The main idea of the passage is “four kinds of consumers”.
42.The underlined word “scavenger” means“食腐动物” in Chinese.
43.The food for a mouse according to the picture is a grasshopper.
44.All kinds of animals share their living places with others.
45.There are some living things which don’t need to eat food.
