    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.
It can be inferred from the passage that we need to control noise pollution if______.
选项 A、we want to stay both psychologically and physically healthy
B、we don’t want to be angry with others
C、we want to work hard and cooperate well with each other
D、we don’t want to suffer from serious anxiety and feel uneasy
答案A
解析 推断题。依据是最后一句：It is noise pollution that we need to control in order to help people live more happily．live more happily和选项A中的stay both psychologically andphysically healthy相对应。选项B、C、D中的暴躁易怒、难以合作、感到焦虑等都是第一段提到的噪音对人们的不良影响, 属于细节, 不是我们要控制噪音污染的主要目的。
