根据下面资料，回答下列问题。
Professor Smith recently persuaded 35 people,23 of them women, to keep a diary of all their absent-minded actions for a fortnight. When he came to analyze their embarrassing lapses in a scientific report, he was surprised to find that nearly all of them fell into a few groupings. Nor did the lapses appear to be entirely random.
One of the women, for instance, on leaving her house for work one morning threw her dog her earrings and tried to fix a dog biscuit on her ear. "The explanation for this is that the brain is like a computer," explains the professor. "People program themselves to do certain activities regularly. It was the woman´s custom every morning to throw her dog two biscuits and then put on her earrings. But somehow the action got reversed in the program." About one in twenty of the incidents the volunteers reported were these "program assembly failures."
Altogetherthe volunteers logged 433 unintentional actions that they found themselves doing--an average of twelve each. There appear to be peak periods in the day when we are at our zaniest (滑稽的). These are two hours some time between eight a.m. and noon, between four and six p.m. with a smaller peak between eight and ten p.m. "Among men the peak seems to be when a changeover in brain ´program´ occurs, as forinstance between going to and from work." Women on average reported slightly more lapses--12.5 compared with 10.9 for men.
Which of the following about the study is true?
细节题。根据第一段第一句“Professor Smith recently persuaded 35 people，23 of them women，to keep a diary of all their absent-minded actions fora fortnight．”可知，A、D项错误，B项正确，fortnight意为“l4天，两星期”。根据第一段最后一句“Nor did the lapses appear to be entirely random．"可知， 人们无意中做错的事并不是随机出现的，C项错误。
The peak periods of absent-minded actions include the following EXCEPT ________.
细节题。根据题干中的关键词“peak periods”定位至第三段。根据第三句“These are two hours some time between eight a.m. and noon, between four and six p.m. with a smaller peak between eight and ten p.m.”可知．无意中出差错的高峰期不包括C项。
According to the passage, which of the following statement is true?
细节题。根据第三段中的“an average of twelve each”可知，整体的平均数是12，但并不意味着每个人都正好有12次过失，故A项错误。根据第二段 中的“One of the women…one morning threw her dog her earring sand tried to fix a dog biscuit on her ear．…It was the woman’s custome very morning to throw her dog two biscuits and then put on her earrings．"可知。这个女人的习惯是每天早上把狗食扔给狗．然后戴上耳环，“把耳环当作狗食扔给狗”只是她某一 天早上无意中做错的事，并不是习惯性的行为，故B项错误。根据第二段中的“the brain is like a computer…People program themselves to do certain activities regularly. It was the woman´s custom every morning to throw her dog two biscuits and then put on her earrings. But somehow the action got reversed in the program.About one in twenty of the incidents the volunteers reported were these program assembly failures."可知，人的大脑程序有时也会出错，故D项错误。根据 第三段最后一句“Women on average reported slightly more lapses--12.5 compared with 10.9 for men."可知，C项正确。
This passage is a piece of________.
推断题。exposition“说明文”，侧重于解释、说明某事物、某现象、某情况等；description“描写文”，描写某人、某物；narration“记叙文”，讲述 一个故事；argumentation“议论文”，目的在于使人们信服自己的立场、观点。本文主要介绍了史密斯教授对人们无意中出差错这一现象的研究结果。研 究表明，这种现象无论在发生的事情方面，还是在发生的时间方面，都有一定的规律性。本文既不是讲故事，也没有大量的描写，也没有表明作者自 己的观点并进行论证，而是说明文。故选A。
