问题     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 become more irritable and less cooperative; in more permanent noisy situations, many people cannot 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 (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.  
People enjoy listening to music, ______.
选项 A、though they are receiving a lot of decibels of sound
B、because it does not have any negative effect
C、because they don’t have to tolerate the noise around that
D、although it is sometimes unpleasant to hear strange sounds
答案A
解析 本题仍然是一道具体细节题。问人们喜欢欣赏音乐，原因或环境是什么。利用查阅式阅读法，文章第三段指出，相比之下，如果有人在音乐会听音乐时，两个人在他背后低语，即使声音不大，你也会感到他们的谈话很吵。你之所以意识到这些噪声，是因为受到了心理的影响。声音及噪音均具有负面的影响，但关键问题是，人们能否控制声音。有人在街上边走边听耳机里悦耳的音乐，他们会听到许多分贝的声音，但是，他们乐意听他们能够控制的声音。因此，本题的正确答案应是A“虽然他们听到的声音分贝很大”。
