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 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 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 want to wipe those memories out, "said Rebecca Dresser, a medical ethicist.

Michael Fish may soon be replaced as a weather forecaster by something truly fishier---the shark(鲨鱼).
Research by a British biology student suggests that sharks could be used to predict storms.
Lauren Smith, 24, is close to completing her study on shark’s ability to sense pressure.
If her studies prove the theory, scientists may be able to monitor the behaviour of sharks to predict bad weather.
Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas.
She then used their close relatives, lesser spotted dogfish, for further research at Aberdeen University.
Her work---thought to be the first of its kind to test the pressure theory ---- resulted from the observation that juvenile blacktip sharks(黑边鳍真鲨) off Florida moved into deeper water ahead of a violent storm in 2001.
Miss Smith said: “I’ve always been crazy about traveling and diving and this led me to an interest in sharks.”
“I was delighted to have been able to research in the area for my degree. I know there’s so much more we need to understand ---- but it certainly opens the way to more research.”
It has been discovered that a shark senses pressure using hair cells in its balance system.
At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.
In Aberdeen, she was able to study the effects of tidal(潮汐的) and temperature changes on dogfish----none of which were harmed. She also used a special lab which can mimic(模拟) oceanic pressure changes caused by weather fronts.
She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.The passage is most probably taken from _____.

One August afternoon, Richard Allen dropped off his last passenger, Mrs. Carey. Lifting two grocery bags, he followed her across the yard and stood on the step of her house. Glancing up, he saw a large wasp（黄蜂） nest under the roof. Allen had heard that wasps can become more likely to sting (sting, sting, stung蜇) in summer. He mentioned this to Mrs. Carey, who had opened the door.
“Oh, they don’t bother me,” she said lightly. “I go in and out all the time.”
Anxiously, Allen looked at the nest again—— to see the wasps flying straight at him. “Hurry!” he shouted to Mrs. Carey. “Get in!”
She stepped quickly inside. Allen ran for his mini-bus. Too late; they were upon him. Just as he jumped aboard, half a dozen red spots showed on his arm, and he felt more on his back and shoulders.
As he was driving down the road, Allen felt as if something was burning at the back of his neck, and the “fire” was spreading forward toward his face. And immediate anxiety took hold of him. Allen knew that stings could cause some persons to die. But he had been stung the previous summer and the after-effects soon passed. However, what he didn’t know what that the first sting had turned his body into a time bomb waiting for the next to set off an explosion.
Miles from the nearest medical assistance, Allen began to feel his tongue thick and heavy and his heartbeat louder. Most frightening, he felt his breathing more and more difficult. He reached for the radio mike（话筒）, trying to call the mini-bus center, but his words were hardly understandable. Signals were also poor that far out. He knew a rescue team was on 24-hour duty at the Amherst Fire Department’s north station. So his best chance was to make a run for it.
Rushing down the mountain, Allen tried not to panic, focusing his mind on each sharp turn. He was almost through the last of them when he felt sure he was going into shock（休克）. Just then he reached for the radio mike again.
“Call fire station,” he shouted, concentrating to form the words. “Emergency. Bee sting. Emergency. There in ten minutes.”
“Five-ten,” the center replied.
Hold on, Allen thought. Keep your eyes open. Breathe. Keep awake.
At last he reached the station. Two firemen ran out. Allen felt their hands grasp him before he hit the ground. You made it, he thought.It is mentioned in the passage that wasps are more likely to attack when _______.
| A．there are huge noises | B．strangers are approaching |
| C．the air is filled with food smell | D．the hottest season comes around |
Allen didn’t know that if stung by wasps again, he would _______.
| A．have no after-effects | B．suffer from sharper pain |
| C．surely lose his life | D．become more sensitive |
Allen failed at his first attempt to send his message to the mini-bus center because _______.

| C．he was in a state of shock | D．no one was on duty |
Which would be the best title for the passage?
| A．Allen, A Helpless Driver | B．Wasps, Bloody Killers |

Napoleon, as a character in Tolstoy’s War and Peace, is more than once described as having “fat little hands.’’ Nor does he “sit well or firmly on the horse.’’ He is said to be “undersized.’’ With “short legs’’ and a “round stomach”. The issue here is not the accuracy of Tolstoy’s description--it seems not that far off from historical accounts but his choice of facts：other things that could be said of the man are not said. We are meant to understand the difference of a warring commander in the body of a fat little Frenchman. Tolstoy’s Napoleon could be any man wandering in the streets and putting a little of powdered tobacco up his nose—and that is the point.
It is a way the novelist uses to show the moral nature of a character. And it turns out that, as Tolstoy has it, Napoleon is a crazy man. In a scene in Book Three of War and Peace, the wars having reached the critical year of 1812,Napoleon receives a representative from the Tsar(沙皇), who has come with peace terms. Napoleon is very angry：doesn’t he have more army? He, not the Tsar, is the one to make the terms. He will destroy all of Europe if his army is stopped. “That is what you will have gained by engaging me in the war!” he shouts. And then, Tolstoy writes, Napoleon “walked silently several times up and down the room, his fat shoulders moving quickly.’’
Still later, after reviewing his army amid cheering crowds, Napoleon invites the shaken Russian to dinner. “He raised his hand to the Russian’s…face,” Tolstoy writes, and “taking him by the ear pulled it gently….” To have one’s ear pulled by the Emperor was considered the greatest honor and mark of favor at the French court. “Well, well, why don’t you say anything?’’ said he, as if it was ridiculous in his presence to respect any one but himself, Napoleon.
Tolstoy did his research, but the composition is his own. Tolstoy’s description of Napoleon in War and Peace is _________.
| A．far from the historical facts |
| B．based on the Russian history |
| C．based on his selection of facts |
| D．not related to historical details |
Napoleon was angry when receiving the Russian representative because _________.
| A．he thought he should be the one to make the peace terms |
| B．the Tsar's peace terms were hard to accept |
| C．the Russians stopped his military movement |
| D．he didn’t have any more army to fight with |
What did Napoleon expect the Russian representative to do?
| A．To walk out of the room in anger. |
| B．To show agreement with him. |
| C．To say something about the Tsar. |
| D．To express his admiration. |
Tolstoy intended to present Napoleon as a man who is _________.
| A．ill-mannered in dealing with foreign guests |
| B．fond of showing off his iron will |
| C．determined in destroying all of Europe |
| D．crazy for power and respect |
What does the last sentence of the passage imply?
| A．A writer doesn’t have to be faithful to his findings. |
| B．A writer may write about a hero in his own way. |
| C．A writer may not be responsible for what he writes. |
| D．A writer has hardly any freedom to show his feelings. |

People believe that climbing can do good to health. Where can you learn the skill of climbing then? If you think that you have to go to the mountains to learn how to climb, you’re wrong. Many Americans are learning to climb in city gyms(体育馆). Here, people are learning on climbing. The climbing wall goes straight up and small holding places for hands and feet.
How do people climb the wall? To climb, you need special shoes and (保护带) around your chest to hold you. There are ropes(绳索)tied to your. The ropes hold you in place so that you don’t fall.
