We had known for along time that flowers of different plants open and close at different time of day. Yet no one really understands why flowers open and close like this at special time. The question is not as simple as we might think, as recent experiments have shown. In one experiment, flowers were kept in constant (持續(xù)的）darkness. We might expect that the flowers ,without any information about the time of the day, did not open as they usually do. In fact, they continue to open at their usual time. This shows that they have some special ways of knowing the time. Their sense(感覺(jué)) time does not depend on information from the outside world. It is inside them: a kind of "inner (內(nèi)部的）clock". This discovery may not seem to be very important. However, it is later found that not just plants but animals have this "inner clock" which control（控制）the working of their bodies and influences their activities. Human beings, then, are also influenced by it. Whether we wish or not, it affects such things in our life as our need for sleep or need for food.

A. never open in constant darkness                      B. change their usual time to open

C. open ahead of the time as they usually did         D. continue to open at usual time

54.The sense of time that flowers have is connected with_____________.

A. its age and size                                         B. light and temperature

55. What will happen if we make good use of the "inner clock"

A. We'll need less sleep or food.                    B. We'll be able to sleep as long as we wish to.

C. We'll be able to change our work time when necessary.

D. We'll have more energy to do our work better.

   Sam, a dog, was left behind in Colorado while his owners, Mr. And Mrs. Green moved to Southern California. They did not give the dog up. They found him a very nice home before they moved. They would have let Sam accompany them, but they were afraid the dog’s presence would make it difficult for them to rent a house when they reached their destination.

     The Green family lived in Colorado for less than a year. Before that, they had lived in the same neighborhood in California to which they returned. So Sam had been there before, but only for a short time when he was young.

     Several months after the Greens left Colorado, after they were comfortably settled back in California, they heard a scratch at the door. They couldn’t imagine who might be there. It never occurred to them that it might be Sam, because they were sure he was happily set up with his new family back in Colorado. When they opened the door, the Greens saw a dirty, tired dog with very hurting feet. The animal looked a little bit like Sam, but no one could believe that Sam could have walked 840 miles on his own. The tired dog spent the night under the family car. The next day, when he was more rested, he performed some of his old tricks. The Greens knew they had their own dog back.

   A good memory is a great help in learning a language. Everybody learns his own language by remembering what he hears when he is a small child, and some children, like boys and girls who live abroad with their parents, seem to learn two languages almost as easily as one. In school it is not easy to learn a second language because the pupils have so little time for it, and they are busy with other subjects, too.

A man’s mind is rather like a camera, but it takes photos not only of what we see but of what we feel, hear, smell and taste. When we take a real photo with a camera, there is much to do before the photo is finished and ready to show to our friends. In the same way there is much work to be done before we can keep a picture forever in our mind.

Memory is the diary that we all carry about with us.

41. We usually begin to learn our own language by ________ it.
