No one knows exactly why we sleep. But scientists have learned a lot about how we sleep.
When you first fall asleep, your heart starts to beat more slowly and your breathing slows down. If something wakes you, you might not think that you had been asleep. Some people call it dozing (打盹). Next, you enter into a deeper sleep. Your pulse (脉搏) and breathing become even slower. But you can still be awakened quite easily. If you take a catnap, you probably will not get any further than this stage (阶段) of sleep. If you sleep longer than about twenty minutes, you get into the third one. Your body is very relaxed. It would take a loud noise to wake you up. You may have heard of people who walk in their sleep. No one knows what makes people sleepwalk. But a person can sleepwalk only during stage four. This is the last and deepest kind of sleep. If someone wakes you up, you might feel very uncomfortable and you need a few minutes to get used to being awake. A

Early or Later Day Care
The British psychoanalyst John Bowiby maintains that separation from the parents during the sensitive "attachment"period from birth to three may scar a child's personality and predispose to emotional problems in later life.Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it entails,and many people do believe this.But there are also arguments against such a strong conclusion.
Firstly,anthropologists point out that the insulated love affair between children and parents found in modern societies does not usually exist in traditional societies.For example,in some tribal societies,such as the Ngoni,the father and mother of a child did not rear their infant alone-far from it.Secondly,common sense tells us that day care would not be so widespread today if parents,care-takers found children had problems with it.Statistical studies of this kind have not yet been carried out,and even if they were,the results would be certain to be complicated and controversial.Thirdly,in the last decade there have been a number of careful American studies of children in day care,and they have uniformly reported that day care had a neutral or slightly positive effect on children's development.But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.
But Bowlby's analysis raises the possibility that early day care has delayed effects.The possibility that such care might lead to,say,more mental illness or crime 15 or 20 years later can only be explored by the use of statistics.Whatever the long-term effects,parents sometimes find the immediate effects difficult to deal with.Children under three are likely to protest at leaving their parents and show unhappiness.At the age of three or three and a half almost all children find the transition to nursery easy,and this is undoubtedly why more and more parents make use of child care at this time.The matter,then,is far from clear-cut, though experience and available evidence indicate that early care is reasonable for infants.
It is suggested that modern societies differ from traditional societies in that______.
A.the parents-child relationship is more exclusive in modem societies
B.a child more often grows up with his/her brothers or sisters in traditional societies
C.mother brings up children with the help of her husband in traditional societies
D.children in modem societies are more likely to develop mental illness in later years
