Passage Two
The sense of sound is one of our most important means of knowing what is going on around us. Sound has a waster product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better.
Scientists, for several years, have been studying how noise affects people and animals. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.
There is a saying that it is so noisy that you can’t hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don’t, we may have headaches, other aches and pains, or even worse mental problems.
Noise adds more tension (紧张) to a society that already faces enough stress.
But noise is not a new problem. In ancient Rome, people complained so much about noise that government stopped chariots (四轮马车) from moving through the streets at night!
Ways of making less noise are now being tested. There are even laws controlling noise. We cannot return to the "good old days" of peace and quiet. But we can reduce noise--if we shout loudly enough about it.

Why are scientists surprised by the findings in their noise study（）

A:Because the world is becoming more and more noisy. B:Because they have learned that noise is also a kind of pollution. C:Because noise is an unwanted waste for human beings. D:Because people knew little about noise before.

Psychologists now believe that noise has a considerable effect on people’s attitudes and behavior. Experiments have proved that in noisy situations (even temporary ones), people would have more irritability (躁易怒) and less cooperation. In more permanent noisy situations, many people cannot work hard, and they suffer from severe anxiety as well as other psychological problems. Some researchers, who study various aspects of effect of noise in people’s mental life, maintain that noise, either temporary noise or permanent noise, often destroy creativity and activity by disturbing people’s emotion and make them more irritable and hard to cooperate.
However, psychologists distinguish between "sound" and "noise". "Sound" is measured physically in decibels (分贝). "Noise" cannot be measured in the same way because it refers to the psychological effect of sound and its level of "intensity" depends on the situation. Thus, for passengers at an airport who expect to hear airplanes taking off and landing, there may be a lot of sound, but not much noise (that is, they are not bothered by the noise). By contrast, if you are at a concert and two people behind you are whispering, you feel they are talking noisily even if there is not much sound. You notice the noise because it affects you psychologically. Both sound and noise can have negative effects, but what is most important is if the person has control over the sound. People walking down the street with earphones, listening to music that they enjoy, are receiving a lot of decibels of sound, but they are probably happy hearing sounds which they control. On the other hand, people in the street without earphones must tolerate a lot of noise which they have no control over. It is noise pollution that we need to control in order to help people live more happily.

A:can not complete his work in a noisy situation B:will suffer from complete deafness because of noise pollution C:can be psychologically affected by working in very noisy factories D:may cooperate well in a noisy surrounding
