Unless action is taken immediately, there is a chance that all the oceans of the world will be dead by the year 2010. How can this possibly happen?

We have already seen that people allow all sorts of waste products to flow into the sea. It is almost impossible to measure how much waste water and industrial waste end up in our oceans, but we can find out how much oil is poured into them legally and illegally. It is illegal to pour oil into the sea close to the shore, but when a ship is many miles out to sea there are no such rules. Scientists have different ideas as to the amount of oil put into the sea, but the lowest figure for oil poured in European waters alone is about 200,000 tons every year. Some people say the figure could be ten times as high.

It is not only our coasts that suffer from oil pollution. Among other things, many shellfish - oysters (牡蛎) and mussels(贻贝), for example - now have high amounts of poisonous substances. Next time you have shellfish to eat, how can you be sure that they are free from oil pollution? You cannot see the effects and you cannot taste them, either. It is really quite a problem.

1．This passage is mainly about_________.

     A．pollution in the air                       B．the amount of the oil in the sea

     C．the amount of poison in shellfish         D．oil pollution in the waters.

2．According to the passage, what is the main cause of oil pollution?

       A．Oil ships which meet and strike each other.

       B．Oil poured on land when the oil tanks are cleaned out.

       C．Oil coming out of the bottom of the sea.

       D．Oil from waste water and industrial waste.

3．According to the passage, which of the following is illegal?

       A．Pouring oil into the sea close to the shore.

       B．Allowing clean materials to flow into the waters.

       C．Smoking.

       D．Going fishing when the water is polluted by oil.

4．The figure for oil poured in European waters alone is          .

       A．no more than 2,010,000 tons every month

       B．1,000,000 tons every year

       C．more than 200,000 tons every month

       D．more than 200,000 tons every year

5．Which of the following statements is WRONG according to the passage?

       A．All the oceans in the world are polluted by oil.

       B．The water body of the earth may be dead by the year 2010.

       C．It is not only our coasts that suffer from oil pollution.

       D．Some kinds of the living things in the waters have been poisoned and we must be careful of them.

　　The earth is our home. We must take care of it. This means keeping the land, air and water clean.

　　Pollution(污染)is a “dirty” word. To pollute means to make things unfit or unclean to use. Pollution comes in many ways; we see it, smell it, taste it and drink it. Pollution it beginning to threaten(威胁)out health, out 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 water. There weren’t many people and then their wants were 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 population and the development of industry have changed that. Man is slowly poisoning his environment(环境).

　　Once we thought of pollution, we simply mean air pollution. Though it is still the most dangerous, air pollution is only type of pollution.

　　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(垃圾堆), or is there any hope that we can get rid of (除掉)the pollution.

　　Fortunately millions of people have been warned(警告)of the danger of pollution. Large numbers of people are now working hard to bring pollution under control(控制).
