The earth is our home, and 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 unfit(不合适的) or unclean to use. Pollution comes in many ways. We see it, smell it, taste it and drink it. Pollution is beginning to threaten(威胁) our health, or 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 to another place. At first the problem was not so serious(严重) because there was plenty of clean air, land and water. There weren’t so many people then and their wants were fewer. All the dirty things could be absorbed(吸收) by nature and soon covered over(恢复). But this is no longer true. The increase of population(人口增长) and the development of industry have changed that. Man is slowly polluting his environment.

Through the use of poison(农药), man has polluted land killing the animal. 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, or is there any hope that we can get rid of(摆脱) 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.

文章大意:本文主要介绍了两个测试第六感的实验,通过实验告诉我们第六感并不存在。

【推荐1】Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you!

Parapsychologists(灵学家) say that humans have a natural ability to sense when someone is looking at them. To study if such a “sixth sense” really exists(存在), Robert Baker, a psychologist at the University of Kentucky, did two experiments(实验).

In the first one, Baker sat behind unknowing people in public places and stared(盯着看) at the backs of their heads for 5 to 15 minutes. The subjects(受试者) were eating, drinking, reading, studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the subjects, almost all of them said they had no sense that someone was staring at them.

For the second experiment, Baker told the subjects that they would be stared at from time to time from behind. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t.

Baker concludes that people do not have the ability to sense when they’re being stared at. If people don’t believe the outcome of his two experiments, said Baker, “I advise they repeat the experiments and see for themselves.”

1. What’s the purpose of the two experiments?
A.To explain why humans have a sixth sense.
B.To show how people act while being watched.
C.To explain when people can have a sixth sense.
D.To study if humans can sense when they are stared at.
2. What sense do humans have according to parapsychologists?
A.A natural ability.B.A looking feeling.C.A strange thinking.D.A natural staring ability.
3. The underlined word “outcome” in the last paragraph means ________.
A.factB.resultC.exampleD.content
4. What can we learn from the passage?
A.People are born with a sixth sense.
B.People have a sixth sense in all places.
C.The experiments support parapsychologists’ idea.
D.The subjects do not have a sixth sense in the experiments.

【推荐3】Shopping for clothes is not the same for men as it is for women.     1     He knows what he wants, he can decide what to buy before shopping. So most men simply walk into a shop and ask someone for what they want. If the shop has it and the price is good, they often finish shopping in less than five minutes.

For a man, some problems may begin when the shop does not have what he wants.     2     He offers(提供)something that is almost the same as the thing the man wants. Good salespeople say, “    3     Sir, but would you like to try it for size? Maybe you like the color.” Most men don’t care about this and may answer, “This may be the right color and the right size, but I won’t waste(浪费) my time trying it on.”

For a woman, it is different.     4     She doesn’t decide what she wants before she goes shopping. She just goes to “have a look around”.
