答案解析

5l A “to be guilty of,’是固定搭配，表示“有……之过”的意思。

52 C 根据上下文，此处应选表示“引起”之意的词语。

53 D 表示“长时间”应用“long period softime”。

54 A “只有高声喊叫才能”之后显然应选“被人听到”。

55 C 句子要表达的意思是，如果只有高声喊叫才能被人听到，那么就有耳内机制受损的可能。

56 A 要表达“暴露于”或者是“接受了”的意思，应选“exposed to"。

57 B 要表达“听力不如原来好”，此处应选能修饰动词“hear"’而又表示“好”的副词。

58 C 因为接下来讲的是：这些毛病通常会消失，而你的听力很快也会恢复正常，所以这是件幸运之事。

59 A “over and over”是固定搭配，表示“不断”的意思。

60 C 根据上下文，此处应选表示“戴”之意的词语。全句的意思是：建筑工人和在工厂里工作的人们必须戴护耳器，因为他们所使用的设备会产生巨大的噪音。

61 A 根据上下旬，此处应选表示“影响”之意的词语。全句的意思是：然而，即使是一些割草和电动工具也会对人听高音的能力产生永久性的影响，并且也有可能给他造成永久性的耳鸣。．

62 D 前一句讲的是噪音对听力的影响。句子所讲的是反复收听高音量的音乐会对听力产生同样的影响。

63 C 空格所填的词连接着一个主句和一个从句，而从句表示的又是主句的原因，因此不难做出选择。

64 A 文章最后一段是对前面所谈到内容的总结。前面分别提到了器械与音乐所产生的噪音，而此旬已经提及器械，因此接下来要选的应是与音乐有关的，即音乐会。

65 B 文章最后一句的意思是：听音乐时戴耳机是可以的，只是一定要确保音量不要太高，并且每过一段时间想着把耳机摘下来休息休息耳朵。“once in a while”是固定搭配，表示“偶尔，有时”的意思。
