问题     Researches 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 44 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D

解析 第一段最后一句:一个针对在工业化和非工业化地点生活的研究比较认为,年龄的增长不一定导致听力的丧失。因此可以得出D项为正确答案“在工业化地区生活的人们将在老年时遭受听力的丧失”。
