补全漫笔 第七篇 Power Napping is Good for the I.Q.
Today we hear more and more about the importance of getting enough sleep—about eight hours a night. Sleep can help heal and give energy to both the body and the brain. ____1____ It seems almost certain that the third of our lives that we spend asleep has a great effect on the two-thirds that we are awake. Sleep affects our emotions, memory, focus, and behavior.
Studies show that people in developed countries spend less time asleep and more time at work or commuting. Dr. Karine Spiegel, at the University of Chicago, has found that the average length of sleep has gone down from nine hours a night in 1910 to seven-and-a-half hours a night today. However, our bodies cannot function well without enough sleep. ____2____ According to Canadian scientist Dr. Stanley Coren, every hour of lost sleep at night causes us to lose one I.Q. point the next day. For example, when someone gets only five or six hours of sleep each night for a week, the person’s I.Q. could go down 15 points or more. ____3____
Most sleep experts say that humans need at least eight hours of sleep every day, but it should be in two stages: a long sleep at night and a shorter nap in the afternoon. Some companies help their employees follow this advice. ____4____ They say this makes the workers much more efficient.
To study sleep deprivation (not getting enough sleep), scientists use a test called the Multiple Sleep Latency Test (MSLT). During the test, a person stays in a darkened, quiet room during the daytime. Scientists believe that a sleep-deprived person will fall asleep quickly. If it takes ten minutes or longer to fall asleep, the person is probably getting enough sleep.
Scientists have also found that the time of year seems to affect how much sleep we need. ____5____ However, in the summer, people sometimes sleep as little as six hours, without having any problems.

谜底与题解：

2.B 该选项对就寝削减的效果停止了描写，与前一句中“在贫乏充足就寝的环境下，咱们的身材没法一般运作”构成照应，是一个成果性的诠释，固然选项F也是对就寝缺乏人群效果的诠释，可是选项F在此不合适下面一句话的语境，其首要是在描写就寝和智商间接的干系，鄙人文才有所说起，故谜底为选项

4.A 该题的做题线索也是对其前一句的话的补充申明，前文中提到了一些公司在就寝方面临其员工停止了赞助，该选项则冗长先容了这些公司都采用了哪些详细计划。
5.C 本题的做题线索为高低文搭配，在最初一段的第一句中较着说起了就寝和一年中的差别期间有关，前面最初一句话又讲到了夏日的就寝时候，那末从中能够判定出，这里描写的应当是别的一种季候的就寝时候，从而与段首概念句照应并与下句构成对照，而选项C描写的便是夏季的就寝时候，故合适请求。
