     Do you know why you sleep? You may think it's because
you're tired. Or perhaps you've been told sleep
is good for you. Yet no one knows exactly why or how people sleep.
      Until the early 1950s, most scientists thought the body and brain rested during sleep. Then a scientist
watched people sleep. He noticed that during periods of between 5 and 30 minutes, sleepers' eyes made
rapid movements, as if they were watching something. He called these periods REM (Rapid Eye Movement)
sleep. He called periods when sleeper's eyes did not move non-REM sleep.
     Whenever the scientist woke people during REM sleep, they were having vivid dreams. Measurements
showed that sleepers' pulses (脉搏) went up quickly during REM sleep. Their breathing, heartbeat, and the
blood going to the brain also increased. Far from being a time of rest, sleep is a time when the body is hard
at work. Scientists still don't know the reason for this. Some believe REM sleep makes learning easier.
Babies spend a lot of time on REM sleep. Because of this, some scientists believe that REM sleep helps
the brain grow. Others think REM sleep is a time for the brain to empty the day's garbage.
      One thing all the scientists agree on is that sleep is necessary. Without enough sleep, people make
mistakes. Most car accidents happen during the early morning hours, when people are sleepiest.
1. During REM sleep, a person's breathing and heartbeat ______.
A. stop
B. sleep
C. increase
D. stay the same
2. The underlined word "vivid" means ______.
A. easier
B. large
C. empty
D. clear anti lively
3. ______ tells what happens when people don't get enough sleep.
A. Paragraph 1
B. Paragraph 2
C. Paragraph 3
D. Paragraph 4
4. The main idea of this passage is ______.
A. that REM sleep can help the brain grow
B. about the scientific research of REM sleep
C. about how to empty the day's garbage
D. that our body is good at work when sleeping
5. We can know from the passage that _______.
A. enough sleep is very important to people
B. young people can experience REM sleep
C. the speed of sleepers' pulses will slow down during the REM sleep
D. all scientists have the same opinion on REM sleep

"Mummy, I don't know what to play with." Steve stops his mother, who is talking to a friend, for the fourth time. “You've got a room full of toys!" his mother says, impatiently. In fact it is the jumble of toys which is to blame for four-year-old Steve's having no interest in his dolls, cars and animals. Each morning he pours three washing baskets of toys all over his floor, pulls out something and shortly after that, he is standing at his mother's desk or following her into the kitchen saying, "Mummy, I am bored."

A family therapist(心理医生) explains why children lose interest when they have a whole “toy shop” at home. “According to their brain development, little children are not in a position to judge the quality of different kinds of things at once. There is always just one favorite toy for the moment. All the rest are left lying about." What can parents do to stop their children from being oversupplied with toys? Simply make something disappear without the child's knowledge. If he/she takes no more notice of a toy, a parent can ask if it can be stored or given away. Of course the child will always say he/she wants it then!

Lyn is the mother of four-year-old Jessie, and we like her way. A small set of shelves in her child's room holds the toys and books that are the new favourites. When it seems to her that her daughter is tired of these toys, they put them away in a box together and select some other toys from a cupboard in another room. The box of “old” toys goes into the cupboard. When her child says she is "bored", they also get something from her cupboard -- it may be something she has had for some time but because she hasn’t seen it for a while it is almost like a new toy.

Some favourite toys stay out all the time, and there is a collection of dolls which sits in the comer, but in this way Lyn has found that she has fewer toys to put away at the end of the day and her daughter always has something “fresh” to play with.

57. Steve stops his mother several times because______.

  A. he felt uninterested in his toys      B. he disliked his mother's friend

  C. he didn't have enough toys to play with D. he hoped his mother would play with him

58. According to the therapist, children often say they have nothing to play with because______.

  A. they can't play alone for a long time

  B. they are too young to play with so many toys

  C. they are too lazy to pick out their favourites

  D. they don't have the ability to value too many things at a time

59. What does the underlined word "jumble" mean in Chinese?

  A. 单一的选择  B.杂乱的一堆  C.普通的外观  D.相同的形状

60. Which is the advice given to parents in the text?

  A. Buy fewer toys for their children.

  B. Form good habits for their children.

  C. Put some toys away without telling their children.

  D. Spare some time to play with their children.
