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.
【B1】
选项
A、however
B、otherwise
C、likewise
D、therefore
答案
A
解析
此处句意为“以一次单独的旋转来测量,地球每天的时钟是24小时。______,人 类的时钟实际大约是25小时”。根据上下文的意思以及提示词actually,可以判断出本句与 上句是转折关系。所以,正确答案是A.however。otherwise“否则,不然”,likewise“照样,而 且”,therefore“总之,因此”,均不符合题意。
