听力原文: Have you ever felt your mind got confused after a sleepless night? You couldn't come up with an original thought no matter how hard you tried.

You were probably right if you thought that was caused by a lack of sleep. Dr. Home, a sleep researcher in England, studied 24 college students divided into two groups. One group got their normal eight hours of sleep. The other group didn't get the smallest amount of sleep--they stayed awake all night. The next day, Dr. Home tested the students. He asked them questions that required creative and original thinking. One of the questions was "How many uses can a cardboard box be put to?"

The results? The wide-awake students did well on the tests. The tired students did poorly.

Research has already shown that tired people can do okay on tests of routine thinking, like simple addition. But Dr. Home tested creative thinking only.

As part of his study, he offered an amount of money as a reward to the sleepy students if they did well. But even this encouragement wasn't enough to help the students overcome their tiredness. They still did poorly. Dr. Home believes that the cerebral cortex--the part of the brain where thinking takes place--may get worn out during waking hours. Sleep may help to repair the brain overnight. "Without any sleep," he emphasizes, "even if you concentrate harder, you cannot do better." This study gives people something to think about, especially people like hospital workers and airline pilots, who must stay awake all night and then make emergency decisions.

(33)

A.The lack of sleep.

B.The difficult question.

C.The requirement of your creative thinking.

D.The requirement of your original thinking.

听力原文:W: Dr. Smith, you were a political journalist in America and I was told that you'
ve chosen to live there, a mountain village like this in the Himalayan Community. Could you please tell me why you came to India and set fled down here?

M: Yes, of course. I came to India a year ago to have a better understanding of the country. After I arrived, I had to find a place where I could live and write. Of course there were many places for me to choose. But after some months I settled down happily in this village because I like the countryside better and it is a little cooler than those in the plains.

W: Have you ever thought of a typical village as a better choice?

M: Yes, I have. Yet no such thing exists. In fact I wasted a lot of time looking for the typical village. Conditions vary too widely. But the villages I stayed in had much in common--poverty, dirt, and ignorance.

W: But in spite of all this, you still feel very happy. Is the experience in this country so important to you that you came all the way from the United States?

M: Well, that's also the question that the villages ask me. They think that I'm crazy to give up my comfortable life in the United States and isolate myself from the outside world in this remote village, like a retired old man. Why have I come? I've put aside my work as a political journalist because my ideas have changed. I've come to believe that what is happening in the Third World is more important than anything else. But to understand how throe-quarters of the world's people live, and how their future might affect the rest of the world, I feel that I first have to try and share their way of life.

W: I must say I find your view on this issue very convincing. I'm sure when you go back to your own country you'll find your stay here very rewarding.

When did Dr. Smith arrive in India?

A.Several weeks ago.

B.Several months ago.

C.a year ago.

D.Two year ago.

听力原文: Helen was a very successful businesswoman. She had always liked nice clothes. (33)And when she had left school she worked in a shop which sold them, not far from her home. After a few experiments she showed that she was very successful at designing the sorts of things that women want to buy, so after a few years the owner of the shop, who was an old lady, offered to make her a partner. "It's something I should have done long ago," she told Helen with a smile. Helen was very pleased, of course, (34)and when the old lady retired, Helen bought her share and became the sole owner of the shop. Now she had her independence. Ever since she had started in the shop she had have to travel around to see what attractive things her rivals in the clothes trade were producing, to attend fashion shows and so oil. She had always stayed at small cheap hotels, because she dared not to spend too much money when she was saving up to buy a shop of her own. But when she at last became the owner of the shop, and it was making good profits, she found that she had plenty of money, and she felt she should now stay in the best hotels whenever she traveled. (35)"Then the people who buy good clothes can see that your business is successful," she said to herself, "and therefore more of them think they should buy the clothes you make."

(34)

A.She worked in a clothing shop not far from home.

B.She did experiments not far from her home.

C.She stayed at home and designed clothes.

D.She became a partner of an old lady.

The best way to reduce your weight

You hear this:“No Wonder you are fat.An you ever do is eat.”You feel sad:“I skip my breakfast and supper.I run every morning and evening.What else can I do?”Basically you can do nothing.Your genes,not your life habits,determine your weight and your body constantly tries to maintain it.

Albert Stunkard of the University of Pennsylvania found from experiments that.“80 percent of the Children of two obese parents become obese,as compared with no more than 14 percent of the offspring of two parents of normal weight.”

How can obese people become normal or even thin through dieting?Well,dieting can be effective.but the health costs are tremendous.Jules Hirsch,a research physician at Rockefeller University,did a study of eight fat people.They were given a liquid formula providing 600 calories a dayl.After more than 10 weeks,the subjects lost 45kg on average.But after leaving the hospital.they au regained.The results were surprising:by metabolic measurement,fat people who lost large amounts ofweight seemed like they were starving.They had psychiatric problems.They dreamed of food or breaking their diet2.They were anxious and depressed;some were suicidal.They hid food in their rooms.Researchers warm that it is possible that weight reduction doesn’t result in normal weight,but in an abnormal state resembling that of starved non-obese people.

Thin people,however,suffer from the opposite:They have to make a great effort to gain weight.Ethan Sims,of the University of Vermont,got prisoners to volunteer to gain weight.In four to six months,they ate as much as they could.They succeeded in increasing their weight by 20 to 25 percent.But months after the study ended,they were back to normal weight and stayed there.

This did not mean that people are completely without hope in controlling their weight.It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly lower their weight.

The findings also provide evidence for something scientists thought was true—each person has a comfortable weight range3.The range might be as much as 9kg.Someone might weigh 60—69kg without too much effort But going above of below the natural weight range is difficult.The body resists by feeling hungry or full and changing the metabolism to push the weight back to the range it seeks.

The Best Way to Reduce Your Weight

You hear this: "No Wonder you are fat. All you ever do is eat. " You feel sad: "I skip my breakfast and supper. I run every morning and evening. What else can I do?" Basically you can do nothing. Your genes, not your life habits, determine your weight and your body constantly tries to maintain it.

Albert Stunkard of the University of Pennsylvania found from experiments that, "80 percent of the Children of two obese parents become obese, as compared with no more than 14 percent of the offspring of two parents of normal weight. "

How can obese people become normal or even thin through dieting? Well, dieting can be effective, but the health costs are tremendous. Jules Hirsch, a research physician at Rockefeller University, did a study of eight fat people. They were given a liquid formula providing 600 calories (卡路里) a day. After more than 10 weeks, the subjects lost 45 kg on average. But after leaving the hospital, they all regained. The results were surprising: by metabolic measurement, fat people who lost large amounts of weight seemed like they were starving. They had psychiatric problems. They dreamed of food or breaking their diet. They were anxious and depressed (沮丧的) ; some were suicidal. They hid food in their rooms. Researchers warn that it is possible that weight reduction doesn't result in normal weight, but in an abnormal state resembling (类似) that of starved non-obese people.

Thin people, however, suffer from the opposite: They have to make a great effort to gain weight. Ethan Sims, of the University of Vermont, got prisoners to volunteer to gain weight. In four to six months, they ate as much as they could. They succeeded in increasing their weight by 20 to 25 percent. But months after the study ended, they were back to normal weight and stayed there.

This did not mean that people are completely without hope in controlling their weight. It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly lower their weight.

The findings also provide evidence for something scientists thought was true -- each person has a comfortable weight range. The range might be as much as 9 kg. Someone might weigh 60-69 kg without too much effort But going above of below the natural weight range is difficult. The body resists by feeling hungry or full and changing the metabolism to push the weight back to the range it seeks.

What determines your weight?

A.Your working manner.

B.Your eating habit.

C.Your life style.

D.Your genes.
