B 
　Two experts did some experiments on two groups of people — one who tended to sleep less than the
people around them and the other group more.
According to their report that the “short sleepers” had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men automatically began to cut down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.
　　 In general, these “short sleepers” appeared with ambition, active, energetic, cheerful, and conformist (不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or even worked full time while going to school. And many of them had a strong urge to appear “acceptable” or “outstanding” to their friends and associates.
　　When asked to recall their dreams, the “short sleepers” did poorly. More than this, they seemed to prefer not remembering them. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.
　　The experts also stated that those “long sleepers” were quite different indeed. They reported that those men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were a bit concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than the “short sleepers did.
　　Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly express it that being asleep was a good escape from their daily problems.
All in all, proper time of sleeping should be admired, not too long, neither too short.
【小题1】According to the report, ______.

A．are ideally energetic under the pressures of life

B．often ignore the ill effect of not enough sleep

C．do not know how to relax themselves properly

D．are more unlikely to run into mental problems

Dogs are social animals and without proper training, they will behave like wild animals. They will soil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to outlets that are acceptable in the domestic setting.

　　One of the best things you can do for your dog and yourself is to train its obedience. Obedience training doesn’t solve all behavior problems, but it is the foundation for solving just about any problem. Training opens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do.

Training is also an easy way to establish the social rank order. When your dog obeys a simple request of “come here, sit,” it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the pack（群）by using extreme measure. You can teach your dog its subordinate（从属的）role by teaching it to show submission to you. Most dogs love performing tricks for you to

pleasantly accept that you are in charge.

　　Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal.

   When I was in the third grade, I was picked to be the princess(公主)in the school play. For weeks my mother had helped me practice my lines. But once onstage, every word disappeared from my head. Then my teacher told me she had written a narrator's(解说者的)part for the play, and asked me to change roles. Though I didn't tell my mother what had happened that day, she sensed my unhappiness and asked if I wanted to take a walk in the yard.

    It was a lovely spring day. We could see dandelions(蒲公英)popping through the grass in bunches, as if a painter had touched our landscape with bits of gold. I watched my mother carelessly bend down by one of the bunches. "I think I am going to dig up all these weeds," she said. "From now on, we'll have only roses in this garden."

    "But I like dandelions," I protested. "All flowers are beautiful—even dandelions!"

     My mother looked at me seriously. "Yes, every flower gives pleasure in its own way, doesn't it?" she asked thoughtfully. I nodded. "And that is true of people, too," she added.

    When I realized that she had guessed my pain, I started to cry and told her the truth.

　“But you will be a beautiful narrator, ”she said, reminding me of how much I loved to read stories aloud to her.

    Over the next few weeks, with her continuous encouragement, I learned to take pride in the role. The big day finally came. A few minutes before the play, my teacher came over to me. “Your mother asked me to give this to you,” she said, handing me a dandelion. After the play, I took home the flower, laughing that I was perhaps the only person who would keep such a weed.

56.The girl did not play the role of the princess mainly because_______.

A.she felt nervous on the stage.                                 B.she lost her interest in that role.

C.she preferred the role of the narrator                      D.she had difficulty memorizing her words

57.Why did the mother suggest a walk in the garden?

A.To remove the dandelions                                     B.To enjoy the garden scene

C.to have a talk with her daughter.                            D.to help her daughter with the play.

58.What is the main idea of the story?

A.Everybody can find his or her own way to success.  B.Everybody has his or her own value in the world.

C.Everybody should learn to play different roles        D.Everybody has some unforgettable memory.
