Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive (重新体验) 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 (抹去), the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional 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 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 (特质). 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 become 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.”What’s the main idea of the text?

Around the world coral reefs(珊瑚礁) are facing threats(威胁) brought by climate change and great changes in sea temperatures. While ocean warming has been the primary focus for scientists and ocean policy managers, cold events can also whiten corals. A new study by scientists compared damaged to corals exposed to heat as well as cold stress. The results show that cool temperatures can cause more damage in the short term, but heat is more destructive(破坏性的) in the long run.
Climate change is widely known to produce warming conditions in the oceans, but extreme cold-water events have become more frequent and serious as well. In 2010, for example, coral reefs around the world faced on of the coldest winters and one of the hottest summers on record.
During a unique experiment, corals under cold temperatures suffered greater damage in just days compared with heat treated corals. Yet the researchers found that corals were eventually able to adjust to the cold conditions, make their health stable and continue to grow. However, over the long term corals subjected to heat suffered more greatly than those in cold, with evidence of severe whitening and growth stoppage, which leads to death.
The coral’s ability to adjust to cool temperatures surprised the researchers, who say the study’s results show the complexities(复杂性) of monitoring coral health in response to different environmental factors(因素).
“Global warming is associated with increases but also decreases of temperatures,” said Deheyn, one of the researchers. “Not much has been known about the comparative effects of temperature decrease on corals. These results are important because they show that corals react differently to temperature differences, which is important for future management of coral reefs in the field of climate change.”Which of the following is TRUE according to the passage?
| A．Corals are unable to adjust to temperature changes. |
| B．Cold temperature causes greater damage to corals. |
| C．Hot temperature helps coral reefs to grow quickly. |
| D．Heat and cold damage corals in their own ways. |
We can learn from the passage that .
| A．scientists used to pay no attention to the effect of cold events on corals |
| B．2010 witnessed one of the greatest temperature differences on record |
| C．corals prefer warmer conditions to cold temperatures in the long run |
| D．global warming has nothing to do with the decrease of temperature |
According to the research, .
| A．corals may continue to grow in cold events after a few days |
| B．cold events help corals grow more quickly in a short time |
| C．corals show no response to hot temperatures in the first days |
| D．corals are whitened mainly because of warm temperatures |
Scientists reached the conclusion through .
| A．news report | B．scientific study | C．great imagination | D．natural conditions |
Ernest Miller Hemingway (July 21, 1899—July 2, 1961) was an American writer and journalist. His writing style had a strong influence on 20th-century fiction, while his life of adventure and his public image(形象) affected later generations. Hemingway produced most of his works between the mid-1920s and the mid-1950s, and won the Nobel Prize for Literature in 1954.
Hemingway was raised in Illinois. After high school he reported for The Kansas City Star, before leaving for the Italian front to enlist with the World War I ambulance drivers. In 1918, he was seriously wounded and returned home. In 1922, he married Hadley Richardson. The couple moved to Paris, where he worked as a foreign journalist. Advised and encouraged by other American writers in Paris—F. Scott Fitzgerald, Gertrude Stein, Ezra Pound, he began to see his work appear in print there, and in 1925 his first important book, a collection of stories called In Our Time, was published. A year later, he published The Sun Also Rises, a novel with which he scored his first solid success. The writing of books occupied Hemingway for most of the postwar years. He remained based in Paris, but he traveled widely for bullfighting(斗牛), fishing, and hunting that by then had become part of his life and formed the background for much of his writing. Hemingway’s love of Spain and bullfighting resulted in Death in the Afternoon (1932). His position as a master of short fiction had been advanced by Men Without Women in 1927. The harvest of Hemingway’s considerable experience of Spain in war and peace was the novel For Whom the Bell Tolls (1940). In the public view, however, the novel A Farewell to Arms (1929) overshadowed such works.
Shortly after he published The Old Man and the Sea in 1952, Hemingway went to Africa, where he was almost killed in a plane crash that left him in pain or ill-health for much of the rest of his life. Hemingway lived in Florida and Cuba during the 1930s and 1940s, but in 1959 he moved from Cuba to Ketchum, Idaho, where ended his life in the summer of 1961.Which best arranges Hemingway’s works in the correct order of time?

A man may usually be known by the books he reads as well as by the company he keeps. One should always live in the best company, whether it be of books or of men.
A good book may be among the best of friends. It is the most patient and cheerful of companions. It always receives us with the same kindness; amusing and instructing us in youth, and comforting us in age.
Men often discover their similarity to each other by the common love they have for a book just as two persons sometimes discover a friend by the admiration which both entertain for a third. There is an old proverb, “Love me, love my dog.” But there is more wisdom in this: “Love my, love my book.” The book is a truer and higher bond(纽带) of union. Men can think, feel, and sympathize with each other through their favorite author. They live in him together, and he in them.
A good book is often the best container of a life preserving the best that life could think out; for the world of a man’s life is, for the most part, but the world of his thoughts. Thus the best books are treasuries of good words, the golden thoughts, which become our steady companions and comforters.
Books are by far the most lasting products of human effort. Temples and statues decay(腐朽), but good books survive. Time is of no account with great thoughts, which are as fresh today as when they first passed through their author’s minds, ages ago.
