Stop and think about it for a second. Why should we sleep？ __37__ But we sleep every night, even when we have had plenty of rest. There are， no doubt， several different answers to this question, but let39。s just consider one general purpose of sleep: __38__ Human beings are creatures that are normally active during daylight hours, when our senses function most effectively. __39__ We can39。t see objects well, our color vision is entirely lost, and we don39。t have the smelling or hearing sharpness of other animals. So it actually does make sense to have us stay where we are during the dangerous period when night－ waking animals are walking here and there. And one sure way to make sure we don39。t fall down everywhere and get lost or eaten is to have us not move for seven or eight hours, rising again only when the light is back and our survival chances are better. It39。s not the only reason we sleep. __40__Perhaps even the most important one. A. Is it because we get tired? B． Should that put human beings in a terrible situation? C． But from a scientific point of view, this is far from an ordinary matter. D． But in terms of evolution, it may have been one of the first reasons. E． Furthermore, if you were designing an animal, would you have it e into long periods of unconsciousness every twenty－ four hours? F． Sleep as a survival approach. G． At night, humans do rather poorly. 答案： 36～ 40 CAFGD 第三部分 英語知識運用 (共兩節(jié)，滿分 45 分 ) 第一節(jié) 完形填空 (共 20小題；每小題 ，滿分 30 分 ) 閱讀下面的短文，從短文后各題所給的四個選項 (A、 B、 C和 D)中，選出可以填入空白處的最佳選項。 How is a photograph produced?
