问题     Researchers have shown that noise can adversely affect human in both physiological and psychological ways. Hearing losses in particular occupations such as ship - building and constructi - on work are well - known. In fact, however, we all find hearing more difficult as we age. Young ears can distinguish a wide range of sounds from low to very high frequencies, while older ears lose the ability to distinguish high - pitched sounds. A comparison of people living in some industrialized and non - industrialized areas suggests that this hearing loss may not necessarily accompany old age.
    Furthermore, a closer inspection of other data reveals economic effects. For instance, an increased turnover in property has been observed in noisy areas near airports. Job performance can be adversely affected by loud noise, especially if accuracy and mental effort are involved. The use of outdoor areas for conversation is not possible for an estimated 5 to 10 million people who live or work in urban areas. When interference with television or speech or sleep is included , as many as 22 to 24 million people can be said to have lost part of the use of their homes and grounds because of noise.
    Thus noise pollution is a serious environmental concern. The indifferent attitude toward noise should be overcome; considerable efforts should be made to alert people to the grave effects that may stem from an excessively noisy environment.
We can learn from this passage that________.
选项 A、young people are sensitive to high - pitched sounds
B、young people distinguish low frequency noise better than old people
C、high frequency noise can cause hearing loss in old people
D、people in industrialized areas will suffer hearing loss when they are old
答案A
解析 这是一道细节推理的题型。文中第一段提到“In fact，however，we all find hearing more difficult as we age．Young ears can distinguish a wide range of sounds from low to very high frequencies，while older ears lose the ability to distinguish high—pitched sounds．”可以推断出选项A是正确的。而选项B、C和D并未在文中有具体提及，因此不选。
