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.
练习：
A They allow them to "power nap" in the afternoon,if only for 20
minutes.
B Losing just one or two hours of sleep a night,over a long period
of time,can cause serious health problems.
C People usually sleep longer in the winter,sometimes as much
as 14 hours a night.
D People in power are more intelligent because they take naps.
E Medical experts now believe that sleep is even more important
for health than diet or exercise.
F That"s why,without enough sleep,a normally intelligent person
may start to have difficulty doing daily tasks.
答案与题解：
1.E 本题的做题线索为其之前的一句话，即"睡眠能有助于恢复补
充身体和大脑的能量"，其描述的是睡眠的功能，选项E说的也是睡
眠的功能，与前文形成补充说明。
2.B 该选项对睡眠减少的后果进行了描述，与前一句中"在缺少
足够睡眠的情况下，我们的身体无法正常运作"形成呼应，是一个结
果性的解释，虽然选项F也是对睡眠不足人群后果的解释，但是选项
F在此不符合上面一句话的语境，其主要是在描述睡眠和智商直接的
关系，在下文才有所提及，故答案为选项
3.F 从第三段最后一句话看出，选项F描述的是睡眠和智商之间
的联系，其做题线索和上一题一样，都是对前面一句话的结果性补充
描写。
4.A 该题的做题线索也是对其前一句的话的补充说明，前文中提
到了一些公司在睡眠方面对其员工进行了帮助，该选项则简短介绍了
这些公司都采取了哪些具体方案。
5.C 本题的做题线索为上下文搭配，在最后一段的第一句中明显
提及了睡眠和一年中的不同时期有关，后面最后一句话又讲到了夏季
的睡眠时间，那么从中可以判断出，这里描述的应该是另外一种季节
的睡眠时间，从而与段首观点句呼应并与下句形成对比，而选项C描
述的便是冬季的睡眠时间，故符合要求。
