    阅读理解。
         The earth is our home.  We must take care of it.  This means keeping the land, air and water clean.
         Pollution is a "dirty" word. To pollute means to make things dirty. Pollution comes in many forms. We
    see it,  smell it and drink it.   Pollution is beginning to do harm
    ( 损害，伤害) to our health, and even to our life.
         Man has been polluting the earth from the time he first made his fire9 washed his clothes in the river
    and threw his rubbish on the ground.  Many years ago, the problem was not so serious because there
    were not so many people.  All the dirty things would soon be covered up.  There was plenty of clean air,
    land and water.  When the land was used up or the river was dirty in a place, men moved to another
    place.  But this is no longer true.  Man is now slowly polluting the whole world.
       Talking about pollution, we once only meant air pollution. It is true that air pollution is still the most
    dangerous now, but it is only one kind of pollution.
        By using poison ( 毒药), we have polluted the land and killed the animals. By putting dirty water into
    river and lakes, we have polluted our drinking water and killed the fish.  The rise in population is part of
    the problem.  More people,  more rubbish.
         Where is this all to end? Are we turning the world into a big rubbish dump, or is there any hope that
    we can get rid of ( 摆脱，除去) pollution? We are glad to say that the public has been warned of the
    dangers of pollution and a large number of people are working hard to get rid of it.

    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 (威胁) 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(工业) 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(堆存处)，or is there any hope that we can get rid of (摆脱，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.
