We live on the earth. We use the sea around us. What do we take from the ocean? And what do we give to it?

We take fishes from the ocean—millions of kilograms of fish, every year, to feed millions of people.  1.   We take minerals(礦物) from the ocean. We can get salt by evaporating(蒸發(fā)) seawater.  2.    Many other minerals, such as gold, can be also got from the sea, but not by simple evaporation. 3.    Seaweed(海草) becomes food of many kinds— even candy, and ice cream—as well as medicine. Believe it or not, fresh water is another gift from the sea. We can’t drink ocean water.   4.   But ocean water becomes fresh water when the salts are removed. In the future, we will find ourselves depending more and more on fresh water from the sea.

The sea gives us food, fertilizer, minerals, water and other gifts. What do we give the sea? We pollute the ocean all the time. 　 5.　 Throwing waste into the ocean is killing off sea life. Yet as the world population grows, we may need the sea and its gifts more than ever.

We are finally learning that if we destroy our sea, we might also destroy ourselves. Hopefully, it is not too late.

 根據(jù)以上內容，從下列五個選項中選擇適當?shù)木渥舆�原到短文中，使短文完整與正確。將其標號在答題卡上涂黑。（每小題2分，共10分）

A. Other gifts from the sea , such as seaweed, can be also got from the sea.

B. Huge as it is, the ocean can’t hold all that we pour into it.

C. Along with salt, other minerals are left after evaporation.

D. We even use their bones(骨頭) for fertilizer(化肥).

E. Some of its contents(所含物) may cause illness.

The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution.

To pollute means to make things unfit or unclean to use. Pollution comes in many ways. We see it, smell it, drink it and even eat it. Pollution is beginning to threaten (威脅) our health, our happiness and our life.

Man has been polluting the earth from the time he first made fire, washed his clothes in the river and threw his waste on the ground. When land was used up or water became dirty, men moved on to another place. At first, the problem was not so serious because there was plenty of clean air, land and water. There weren’t so many people then and their wants fewer. All the dirty things could be absorbed(吸收) by nature and soon covered over. But this is no longer true. The increase of pollution and the development of industry(工業(yè)) have changed that. Man is slowly poisoning(毒害)not only his environment but also himself.

Through the use of poison, man has polluted the land, killing the animals. By putting dirty water and chemicals into rivers and lakes we have polluted our drinking water, killing the fish.

Our increasing population is part of the problem. More people, more waste.

Where is this all to end? Are we turning the world into a big rubbish dump(堆存處)，or is there any hope that we can get rid of (擺脫，除去) the pollution? Luckily, millions of people have been warned of the danger of pollution. Large numbers of people are now working hard to bring pollution under control.

The earth is our home. We must take care of it. This means keeping the land, air and water clean. And we must take care of the rise in pollution at the same time.

2.In Paragraph4, the underlined word “chemicals” mean ____________.
