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).

For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.
Indoor air pollution can cause a person to feel tired, to suffer eye-pain, headache and other problems. Some pollutants（ 污染 物） can cause breathing disorders, diseases of blood and even cancer, Most scientists agree that every modern house has some kind of indoor pollution. People began to notice the problem in the early 1970s. It is that when builders began making houses and offices they did not waste energy. To do this they built buildings that limited the flow of air between inside and outside. They also began using manmade building materials. These materials are now known to let out harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building― green plants. Scientists do not really know how plants control air pollution. They believe that a plant’s leaves absorb or take in the pollutants. In exchange the plant lets out oxygen through its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square metres of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and more healthy place.
64．Generally speaking, indoor air pollution may be more harmful than the air outside because ________.
A. the man - made building materials let out dangerous gases inside houses
B. there may be more harmful gases outside houses
C. the flow of air indoors is limited
D. indoor air pollution can make a person seriously ill
65．The indoor air pollution is caused________.
A. by the building method through which the builders want to save energy
B. by the limit of the flow of air between inside and outside
C. by the building things which are made of man - made materials
D. not only by the limit of air - flow but also by the man made materials
66．The most effective way to clean the air is to use different kinds of plants because________.
A. they may let out more oxygen which people need
B. they can absorb different kinds of the harmful indoor chemicals
C. they can take in all kinds of indoor pollutants
D. they can make your house prettier and more healthy
