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． The expression“get by”,in the last sentence of the first paragraph is______
A、a confusing expression
B、a rude expression
C、an everyday expression
D、an improper expression
【正确答案】：C
【题目解析】：在原文第一段最后一句中，“get by”这个短语用于描述某些人即便晚上只睡几个小时也能应付过去的情况。这个词组在日常语境中常常用来表示某人或某事物虽然条件有限但还能勉强维持或应对。 A选项“a confusing expression”意为“一个令人困惑的表达”，与原文不符，因为“get by”在此处并不是令人困惑的。 B选项“a rude expression”意为“一个粗鲁的表达”，这同样不符合语境，因为“get by”在这里是中性词，并没有粗鲁的含义。 C选项“an everyday expression”意为“一个日常表达”，这完全符合原文中“get by”的使用情况，即它是一个在日常语境中常见的表达方式。 D选项“an improper expression”意为“一个不恰当的表达”，这也不符合原文，因为“get by”在这里的使用是恰当的。 因此，正确答案是C。
