A lecturer was giving a lecture to his students on stress management. He 21 a glass of water and asked the audience, “How 22 do you think this glass of water is?”

       The students’ answers 23 from 20g to 500g.

       “It does not matter on the absolute 24 . It depends on how 25 you hold it. If I hold it for a minute, it is OK. If I hold it for a(n) 26 , I will have an ache in my right arm. If I hold it for a day, you will have to 27  an ambulance. It is exactly the 28 weight, but the longer I hold it, the 29 it becomes.” The whole audience became silent, lost in thought.

       After a moment, the lecturer continued, “ 30 we carry our burden all the time, 31 , we will not be able to carry on with the burden becoming increasingly heavier,  32 heavy for us to bear.

       “What you have to do is to 33 the glass, rest for a while 34 holding it up again.”

       As is shown in the story above, we have to put down the burden periodically, 35 we can be refreshed and are able to carry on.

       So before you 36 home from work tonight, put the burden of 37 down. Don’t carry it back 38 . You can pick it up tomorrow.

       Whatever burden you are having now on your 39 , let it down for a moment if you can.

Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Vi??olence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive(重温) these experiences in nightmares.                       

Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase the effect of painful memories.

In November, experts tested a drug on people in the US and France. The drug stops the body re??leasing chemicals that fix memories in the brain. So far the research had suggested that only the emo??tional effects of memories may be reduced, not that the memories are erased.

The research has caused a great deal of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war.

They say that there are many people who suffer from terrible memories. “Some memories can ruin people’s lives. They come back to you when you don’t want to have them in a daydream or nightmare. They usually come with very painful emotions.” said Roger Pitman, a professor of psychiatry (精神病学) at Harvard Medical School. "This could relieve(减缓) a lot of that suffering.”

But those who are against the research say that changing memories is very dangerous because memories give us our identity. They also help us all avoid the mistakes of the past. “All of us can think of bad events in our lives that were horrible at the time but make us who we are. I'm not sure we’d want to wipe those memories out.” said Rebecca Dresser, a medical ethicist (伦理学家).

Some people fear that although the drug would first be used in only very serious cases, it would be??come more and more common.“People always have the ability to misuse science,” said Joseph LeDoux, a New York University memory researcher. “All we want to do is help people have better control of memories.”

56. The underlined word “it” in paragraph 4 refers to “_____.”

A. the new drug                       B. the research into the drug

C. the memory                        D. the chemical in the drug

57. Which of the following is Not the opinion of the supporters?

A.The pill can erase all the memories in the past.

B.Some memories can ruin people's life. The pill can relieve emotional suffering.

C. The pill can also help many other types of people who suffer from terrible memories.

D. The pill can prevent or treat troubling memories in soldiers after war.

58. Which of the following is Not the opinion of the opponents (反对者) ?

A. Our memories give us our identity.

B. The memories help humanity avoid mistakes of the past.

C. The drug should be used in only very serious cases.

D. People may not be sure whether they want to wipe the memories out.

59. Which of the following statements might be the main idea of the text?

A. People often suffer from bad memories.    

 B. The nightmares are terrible.

C. Forget bad memories and be happy.

D. The research has caused a heated argument.

Is a recently discovered hormone the reason why folks who lose weight can’t keep it off?

Like millions of other fat people, at 530 inches high, more than 300 pounds, Carnie Wilson was not just fat. After trying all sort of diets that didn’t work, she has to go to the stomach – bypass surgery (胃部迂回手术), ie, have most of her stomach sewed up, only leaving tiny room to hold several tablespoonfuls at most. Result: she simply couldn’t eat the way she used to. In three years, Wilson is one third of her former weight.

Wilson’s experience is not all that unusual, and while doctors still aren’t exactly sure what is going on, a report in last week’s Journal of Medicine offers an explanation. The loss of appetite in bypass patients may be linked to a recently discovered hormone called ghrelin. Not only that, ghrelin may turn out to be one reason we feel hungry and it’s hare for didters to keep weight off.

Nowadays, researchers are careful to stress only what they know for sure. For the three conclusions, the leading Dr. David of the University of Washington says, “I feel very solid about two of them.” The first is that ghrelin levels in the bloodstream rise significantly before meals and drop afterward. The second conclusion is that ghrelin levels are higher on average in people who have lost weight from dieting.

Dr. David is less sure of the third conclusion, that bypass patients have only a quarter as much ghrelin as most people of normal weight. After all, ghrelin is produced by cells in the stomach. Years ago, leptin, a hormone was found as an appetite suppressant (食物抑制剂). But after years of trying, it had to be given up.

What doctors suspect is that both leptin and ghrelin are part of a complex system of brain and body chemicals that govern weight and appetite. That does not mena pharmaceutical (药物的) weight control is forever out of the question. “In the next ten years, we will be able to develop new drugs to help people lose weight healthily and effectively.”

47.What can we learn about ghrelin according to the passage?

       A.After meals ghrelin levels are higher in the bloodstream.

       B.People who have lost weight have less ghreilin in their body.

       C.Without ghrelin, people are really difficult to lose weight.

       D.Ghrelin is something produced by cells in the stomach.

48.What is Dr. David not sure?

       A.pharmaceutical weight control is impossible.

       B.There is less ghrelin in the bypass patients.

       C.new drugs will be developed in 10 years.

       D.ghrelin levels are higher in people on diet.

49.In fact, people’s weight and appetite are controlled by        

       A.ghrelin and leptin                       B.hormone and medicine

       C.brain and body chemicals                   D.stomach and food

50.What can we infer from the passage?

       A.People with a lower ghrelin level go hungry easily.

       B.Doctors managed to use leption to control the appetite.

       C.Doctors are optimistic about how to lose weight healthily.

       D.The loss of appetite in bypass aptient is linked to leptin
