问题     Psychologists now believe that noise has a considerable effect on people’s attitudes and behaviors. Experiments have proved that in noisy situations( even temporary ones), people behave more irritably and less cooperatively; in more permanent noisy situations, many people can not work hard, and they suffer from severe anxiety as well as other psychological problems. However, psychologists distinguish between "sound" and "noise". "Sound" is measured physically in decibels. "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 en joy, are receiving a lot of decibels of sound, but they are probably happy to hear 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.
选项 A、can net 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
答案C
解析 推断题。文章提到噪音会给人的心理带来不良影响，故可以推断C是正确的。选项A和B都过于绝对，而D和原文表述意义相反。故选项C正确。
