The Earth’s daily clock, measured in a single revolution, is twenty-four hours. The human clock,【B1】______, is actually about twenty-five hours. That’s【B2】______scientists who study sleep have determined from human subjects who live for several weeks in observation chambers with no 【B3】______ of day or night. Sleep researchers have 【B4】______ other surprising discoveries as well.
We spend about one-third of our lives asleep, a fact that suggests sleeping,【B5】______eating and breathing, is a fundamental life process. Yet some people almost never sleep, getting by on as 【B6】______ as fifteen minutes a day. And more than seventy years of【B7】______into sleep deprivation, in which people have been kept 【B8】______ for three to ten days, has 【B9】______ only one certain finding: Sleep loss makes a person sleepy and that’s about all; it causes no lasting ill【B10】______. Too much sleep, however, may be【B11】______for you.
These findings【B12】______some long-held views of sleep, and they【B13】______questions about its fundamental purpose in our lives. In【B14】______, scientists don’t know just why sleep is necessary.
Some scientists think sleep is more the result of evolutionary habit than【B15】______actual need, Animals sleep for some parts of the day perhaps because it is the【B16】______thing for them to do: it keeps them【B17】______and hidden from predators; it’s a survival tactic. Before the advent of electricity, humans had to spend at least some of each day in【B18】______and had little reason to question the reason or need for【B19】______. But the development of the electroencephalograph and the resulting discovery in 1937 of dramatic【B20】______in brain activity between sleep and wakefulness opened the way for scientific inquiry in the subject.
【B9】
选项
A、ignored
B、yielded
C、recognized
D、excluded
答案
B
解析
此处句意为“在一项长达70多年对睡眠缺乏的研究中,让人们3至10天不睡觉,______一个肯定的结果:缺乏睡眠让人犯困,仅此而已”。空格所在句的主语为research,宾语为finding,故B.yielded“产生(结果);得出(信息)”符合题意,为正确答案。ignore“忽略”,recognize“认可,承认”,exclude“排除,不包括”,均不符合题意,故排除。
