    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 (暴躁易怒) 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.
According to the passage, people______.
选项 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
答案C
解析 细节题。文章第一段说了在噪音环境中人们受到的影响, 指出很多人无法集中精力工作, 但并没有说他们不能完成自己的工作, 排除A。选项B夸大了事实, 噪音并不会导致完全耳聋；选项D与文章第一段第二句提到的less cooperate相矛盾。选项C正是文章第一段主要说明的问题——噪音会影响人们的心理。
