Question

Doctors have known for a long time that extremely loud noises can cause hearing damage or loss. The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little more than one second to be affected.

An American scientist has found that using aspirin (阿斯匹林) increase the temporary（暂时的）hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great.

The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise.

【解析】

试题分析：很大的噪音有可能导致听力受损或丧失。而实验证明服用大量的阿司匹林会使听力受损状况加重。

1.推理判断题。由Doctors have known for a long time that extremely loud noises can cause hearing damage or loss.可知，医生知道这事很长时间了，就是很大的噪音有可能导致听力受损或丧失。因此选A。

2.第二段第一句话可知，阿司匹林可能会加重噪音导致的听力受损或丧失。故选A。

3.文章最后一段可知，数百位美国人面临着听力丧失的危险，是因为他们服用了大量的阿司匹林。数量远比实验室用的量多得多。 故选A。

4.文章第二段可知，那位美国科学家做实验室想要发现是否服用阿司匹林会使听力受损状况加剧。故选C。
