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.”

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

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.

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.

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.

It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is actually worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect" - holding in heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.

Another view, less widely held, is that increasing particulate (废气排往空中而形成的微粒、颗粒) matter in the atmosphere is blocking sunlight and lowering the earth's temperature ─ a result that would be equally disastrous. A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will offset each other and the world's temperature will stay about the same as it is now.

As pointed out at the beginning of the passage, people used to think that air pollution ______.

       A. caused widespread damage in the countryside

       B. affected the entire eastern half of the United States

       C. had damaging effects on health

       D. existed merely in urban and industrial areas

As far as the greenhouse effect is concerned, the author ______.

       A. shares the same view with the scientists

       B. is uncertain of its occurrence

       C. rejects it as being ungrounded

       D. thinks that it will destroy the world soon

The underlined word “offset" in Para. 2 could best be replaced by______.

       A. slip into    B. make up for       C. set up        D. catch up with

This passage is mainly concerned with ______.

       A. the greenhouse effect                   B. the burning of fossil fuels

       C. the potential effect of air pollution        D. the possibility of a new ice age

Stepping into an old wardrobe, four English schoolchildren find themselves in the magical world of Narnia. On this delightful land, they find friends among the many talking creatures.

The children soon discover, however, that Narnia is ruled by the White Witch. Edmund, one of the children, falls under her power. Who can free Narnia? Only Aslan, the great and noble lion. He alone knows the Deeper Magic. But the children themselves must help fight the battle against the White Witch and those who serve her.

B. The Old Man and the Sea (Ernest Hemingway)

Santiago, an old Cuban fisherman, hasn’t caught any fish in more than 80 days. Sailing far out from land, the old man hooks an enormous fish. That begins an agonizing three?day battle. First he struggles against the great fish. Then he must fight off the sharks that circle the little boat and threaten to eat his fish. Exhausted and bleeding, the old man arrives back at shore. But his fish, his beautiful fish . . .

Hemingway won the Nobel Prize for this superb story of strength and courage, of victory and regret.

C. A Wrinkle in Time (Madeleine Lingle)

Meg’s father, a U.S. government scientist, has been missing for many months. He had been experimenting with time travel when he mysteriously disappeared.

Now Meg, her little brother Charles Wallace and her friend Calvin will try to rescue him. But first they must outwit the forces of evil they encounter on their journey through time and space. Can they find Meg’s father before it’s too late?

This novel is more than just a science?fiction adventure. It’s an exploration of the nature of our universe.

D. The Pearl (John Steinbeck)

One day Kino, a poor Mexican pearl diver, finds a magnificent pearl. With it he dreams of buying a better life, new clothes and schooling for his son. Instead, it brings only evil. His wife pleads with him to get rid of it. "No," says Kino. "I will have my chance. I am a man." But when he kills a man who is trying to steal the pearl, Kino and his wife must run for their lives.

This tale of dreams, justice and the power of greed is told simply and beautifully.

E. The Long Winter (Laura Ingalls Wilder)

It’s winter, 1880—1881, on America’s northern prairies. Mr. and Mrs. Ingalls and their four girls stay near the kitchen stove to keep warm. Heavy snowstorms cut them off even from neighbors. With the trains stopped, no supplies can reach the town. Food and fuel are running out. Day after day the girls must grind wheat for bread and twist hay to burn. At times they nearly lose the battle to keep their spirits up.

This story provides a fascinating glimpse into the life of early American settlers.

F. Jane Eyre (Charlotte Bront??)

Jane Eyre ranks as one of the greatest and most perennially popular works of English fiction. Although the poor but plucky heroine is outwardly of plain appearance, she possesses an indomitable spirit, a sharp wit and great courage. She is forced to battle against the exigencies of a cruel guardian, a harsh employer and a rigid social order. All of which circumscribe her life and position when she becomes governess to the daughter of the mysterious, sardonic and attractive Mr Rochester.

    However, there is great kindness and warmth in this epic love story, which is set against the magnificent backdrop of the Yorkshire moors.
