Mr. Smith went to switzerland. He did not know French or German, and had to communicate through gestures. He attended a physical training course. The instructor made him bend his knees, swing his arms, stretch his neck and shake his head rapidly. He bad to lie on the ground and raise his right and left legs alternately. After a time his muscles grew hard and firm. He forgot the financial crisis and the importance of raising the level of production. He even began to notice individual trees and individual birds.
Finally he returned home. But unfortunately his improvement was only temporary. Soon he was a normal business man again, worried about his property, his profits, his savings, his advancement in a technological society, and things in general.
Mr. Smith went to see his doctor because he ______.
A.had little to eat
B.was seriously ill
C.had to sleep
D.didn' t feel well
Other people feel sure that the present trend is towards too little sleep. To quote one medical opinion, "Thousands of people drift through life suffering from the effects of too little sleep; the reason is not that they can't sleep. Like advancing colonists, we do seem to be grasping ever more of the land of sleep for our waking needs, pushing the boundary back and reaching, apparently, for a point in our evolution where we will sleep no more. This in itself, of course, need not be a bad thing. What could be disastrous, however, is that we should press too quickly towards this goal, sacrificing sleep only to gain more time in which to jeopardize our civilization by actions and decisions made weak by fatigue.
Then, to complete the picture, there are those who believe that most people are persuaded to sleep too much. Dr. H. Roberts, writing in Every Man in Health, asserts it may safely be stated also. It would be a pity to retard our development by holding back those people who are gifted enough to work and play well with less than the average amount of sleep, if indeed it does them no harm. If one of the trends of evolution is that more of the life span is to be spent in gainful waking activity, then surely these people are in the van of this advance.
The author seems to indicate that ______.
A.there are many controversial issues like the right amount of sleep
B.among many issues the right amount of sleep is the least controversial
C.people are now moving towards solving many controversial issues
D.the right amount of sleep is a topic of much controversy among doctors
disappears and recuperation begins. The tired mind gathers new energy, and the memory improves.
Some adults require little sleep; others need eight to ten hours in every twenty-four hours. Infants sleep sixteen to eighteen hours daily, the amount gradually diminishing as they grow older. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive working under pressure may manage on six to eight. Many famous people have little sleep. Napoleon Bonaparte, Thomas Edison and Charles Darwin apparently averaged only four to six hours a night.
Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total more than twelve years. By the age you will also have developed a sleep routine: a favorite hour, a favorite position, and a rule you need to follow in order to rest comfortably.
Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours nearly five days. Whatever the limit, it is absolute. Animals kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.

College Night Owls Have Lower Grades
College students who are morning people tend to get better grades than those who are night owls (晚睡的人), according to University of North Texas researchers.
They had 824 undergraduate(大学本科生的) students complete a health survey that included questions about sleep habits and daytime functioning, and found that students who are morning people had higher grade point averages (GPAs) than those who are night people.
"The finding that college students who are evening types have lower GPAs is a very important finding, sure to make its way into undergraduate psychology texts in the near future, along with the research showing that memory is improved by sleep," study co-author Daniel J. Taylor said in a prepared statement.
"Further, these results suggest that it might be possible to improve academic
performance by using chronotherapy (时间疗法) to help students retrain their biological clock to become more morning types," Taylor said.
The research was expected to be presented Monday at SLEEP, the annual meeting of the Associated Professional Sleep Societies, in Baltimore.
In other findings expected to be heard at the meeting, University of Colorado
researchers found a significant association .between insomnia (失眠) and a decline in college students' academic performance.
The study included 64 psychology, nursing and medical students, average age 27.4 years, who were divided into two groups - low GPAs and high GPAs.
Among those with low GPAs, 69.7 percent had trouble falling asleep, 53.1 percent
experienced leg kicks or twitches (痉挛) at night, 65.6 percent reported waking at night and having trouble falling back to sleep, and 72.7 percent had difficulty concentrating during the day.
"In college students, the complaint of difficulty concentrating during the day continues to have a considerable impact on their ability to succeed in the classroom," study author Dr James F. Pagel said in a prepared statement. "This study showed that disordered sleep has significant harmful effects on a student's academic performance, including GPAs."
41 In the first study, students who stay up late
A had lower GPAs
B had higher GPAs.
C performed equally well in their studies.
D had little difficulty concentrating during the day
【C1】
A.beside
B.next
C.near
D.behind
