Passage Two The thought of not sleeping for twenty-four hours or more is not a pleasant one for most people．The amount of sleep that each person needs varies．In general,each of us needs about eight hours of sleep each day to keep our bodies healthy and happy．Some people,however,can get by 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 on this．Sleep is,after all,a very basic need．But a man named AI 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 negate the claims 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 news-papers．His doctors were baffled by this strange case of permanent insomnia．Herpin offered the only clue to his condition．He remembered some talk about his mother having been injured several days be-fore he had been born．Herpin died at the age of 94,never having slept a wink． This passage centers on______
A、dream interpretation
B、patterns of sleep
C、A1 Herpin's sleepless life
D、sleeps and dreams
【正确答案】：C
【题目解析】：这篇文章主要围绕一个特定的主题进行描述，即AI Herpin的睡眠状况。首先，从文章的第一段和第二段，我们可以看到作者对大多数人睡眠需求的描述和睡眠对身体健康的重要性，但这只是为了引出后文的主题。文章随后详细描述了AI Herpin的情况，一个据说从不睡觉的人，以及医生如何试图验证他的这一特点，但他们始终无法观察到他睡觉。文章通过AI Herpin的例子，展示了一种特殊的、不符合常规的睡眠模式，即永久性的失眠。 现在我们来逐一分析选项： A. dream interpretation（梦的解释）：文章中并没有涉及对梦的解释或分析，所以这个选项与文章主题不符。 B. patterns of sleep（睡眠模式）：虽然文章提到了睡眠对人体健康的重要性，但这不是文章的中心主题。文章主要是围绕一个特殊的案例进行描述，而不是讨论普遍的睡眠模式。 C. A1 Herpin's sleepless life（AI Herpin的无眠生活）：这个选项直接指向了文章的主题，即AI Herpin这个特殊案例。文章详细描述了他的生活习惯、医生如何观察他以及他为何能够不睡觉。 D. sleeps and dreams（睡眠和梦）：虽然这个选项包含了“睡眠”这一关键词，但“梦”的部分在文章中并未得到详细描述或讨论，所以这个选项过于宽泛，没有准确概括文章的主题。 综上所述，文章主要围绕AI Herpin的无眠生活展开，所以正确答案是C。
