【正确答案】 D

【答案解析】[听力原文] The thought of having no sleep for 24 hours or more isn't a pleasant one for most people. The amount of sleep that each person needs varies. In general, each of us needs about 8 hours of sleep each day to keep us healthy and happy. Some people, however, can get by with just a few hours of sleep at night. It doesn't matter when or how much a person sleeps. But everyone needs some rest to stay alive. Few doctors would have thought that there might be an exception to this. Sleep is, after all~ a very basic need. But a man named A1 Herpin turned out to be a real exception, for supposedly he never slept~ A1 Herpin was 90 years old when doctors came to his home in New Jersey. They hoped to challenge the claim that he never slept. But they were surprised. Though they watched him every hour of the day, they never saw Herpin sleeping. He did not even own a bed. He never needed one. The closest that Herpin came to resting was to sit in a rocking chair and read a half dozen newspapers. His doctors were puzzled by the strange case of permanent sleeplessness. Herpin offered the only clue to his condition. He remembered some talk about his mother having been injured several days before he had been born. Herpin died at the age of 94, never, it seems, having slept at all. What is taken for granted by most people? 由短文中提到的But everyone needs some rest to stay alive. Few...thought...exception to this. Sleep is, after all, a very basic need. 可知，大多数人都认为每个人都需要休息来维持生存，因为毕竟睡眠是一个基本需要，故答案为D)。
