Researchers have shown that noise can adversely affect human in both physiological and psychological ways. Hearing losses in particular occupations such as shipbuilding and construction 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
这是一道细节题,可定位在本文第1段“Young ears can distinguish a widerange of sounds from low to very high frequencies,while older ears lose the ability to distinguish high—pitched sounds.”说明年轻人比老年人更能分辨高频声音,选项A是其同义表达。选项B“年轻人比老年人更能分辨低频声音”,与原文不符。第一段的最后一句说,比较生活在工业发达地区和工业不发达地区的人,发现听力损失不一定和年龄的增长有关。它暗示,只有住在工业区的人们听力才会逐渐受到损害。选项C“低频噪声会让老年人听力衰退”和原文主旨不符。选项D“住在工业不发达地区的人年老后会听力衰退”与原文意思不符。
