2020.3公共英语三级考试考前预测试题（阅读理解5）

There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic.

In fact, the very climate of the entire earth may be infected by air pollution. Some scientists, consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil)is creating a "greenhouse effect"--conserving heat reflected from the earth and raising the world′ s average temperature. If this view is correct and the world′ s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.

Another view, less widely held, is that increasing particular matter in the atmosphere is bloc-king sunlight and lowering the earth′ s temperature--a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will offset each other and the world′s temperature will stay about the same as it is now.

Driven by economic profit, people neglect the damage on our environment caused by the "advanced civilization". Maybe the air pollution is the price the human beings have to pay for their develop-ment. But is it really worthwhile?

When a 13-year-old Virginia girl started sneezing, her parents thought it was merely a cold. But when the sneezes continued for hours, they called in a doctor. Nearly two months later the girl was still sneezing, thousands of times a day, and her case had attracted worldwide attention.

Hundreds of suggestions, ranging from "put a clothes pin on her nose" to "have her stand on her head"poured in. But nothing did any good. Finally ,she was taken to Johns Hopkins Hospital where Dr. Leo Kanner, one of the world′s top authorities on sneezing, solved the baffling (难以理解的)problem with great speed.

He used neither drugs nor surgery, curiously enough, the clue for the treatment was found in an ancient superstition about the amazing bodily reaction we call the sneeze. It was all in her mind, he said,a view which Aristotle, some 3,000 years earlier, would have agreed with heartily.

Dr. Kanner simply gave a modern psychological interpretation to the ancient belief that too much sneezing was an indication that the spirit was troubled; and he began to treat the girl accordingly.

"Less than two days in a hospital room, a plan for better scholastic and vocational adjustment,and reassurance about her unreasonable fear of tuberculosis quickly changed her from a sneezer to an ex-sneezer," he reported.

Sneezing has always been a subject of wonder, awe and puzzlement. Dr. Kanner has collected thousands of superstitions concerning it. The most universal one is the custom of begging for the blessing of God when a person sneezes--a practice Dr. Kanner traces back to the ancient belief that a sneeze was an indication that the sneezer was possessed of an evil spirit. Strangely, people over the world still continue the custom with the traditional, "God bless you" or its equivalent.

When scientists look at the sneeze, they see a remarkable mechanism which, without any con-scious help from you, takes on a job that has to be done. When you need to sneeze you sneeze, this being nature′ s clever way of getting rid of an annoying object from the nose. The object may be just some dust in the nose which nature is striving to remove.

A.was ill

B.was mentally ill

C.had heavy mental burden

D.had attracted world-wide attention

7. When the girl began to sneeze continuously，__________.

A.a lot of people offered their advice

B.she was taken to Johns Hopkins Hospital

C.she was given a treatment found in ancient superstition

D.many doctors treated her in different ways

8.Dr.Kanner cured the gid by__________.

A.using Aristotle’s method

B.giving her psychological treatment

C.practicing superstition

D.treating her tuberculosis

9.When a person sneezes，we say“God bless you”because__________.

A.it’s a tradition

B.the person is possessed of an evil spirit

C.the person is ill

D.God will bless those who sneeze
