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.The passage is mainly about ________.
| A．a new medical research |

Wednesday，October fifteenth，is the first Global Hand Washing Day. Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap（肥皂）. Experts say people around the world wash their hands but very few use soap at so-called critical(至关重要的) moments. These include after using the toilet，after cleaning a baby and before touching food.
Global Hand Washing Day is the idea of the Public-Private Partnership for Hand Washing with Soap. Partners include the United Nations Children’s Fund, and soap makers Unilever and Procter and Gamble. The goal，they say，is to create a culture of hand washing with soap.
The organizers say all soaps are equally effective at removing disease-causing germs(病菌). They say the correct way to wash hands is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas，including under the fingernails. Then，rinse（用清水冲洗） well under running water. Finally，dry your hands with a clean cloth.
The Partnership says soap is important because it increases the time that people spend washing. Soap also helps to break up the grease（油脂）and dirt that holds most of the germs. And it usually leaves a pleasant smell，which increases the possibility that people will wash again. It also says washing with soap before eating and after using the toilet could save more lives than any vaccine（疫苗）or medicine. When people get germs on their hands, they can infect themselves by touching their eyes, nose or mouth. Then they can infect others.Global Handwashing Day is set to ______________.
| A．create a culture of hand washing with soap | B．force people to wash their hands |
| C．teach people how to wash their hands | D．protect people from being hurt by germs |
Which one shows the advantages of washing hands with soap?
① increasing the washing time② preventing any infection
③ removing disease-causing germs④ helping people to wash more
⑤ keeping vaccine away
| A．①②③ | B．①②④ | C．②③⑤ | D．①③④ |
The main idea of this passage is to ______________.
| A．introduce Global Handwashing Day | B．remind people to care about their health |
| C．criticize people who don't use soap to wash hands | D．help soap makers to sell more soap |
Everybody hates rats．But in the earthquake capitals of the world-Japan，Los Angeles，Turkey-rats will soon be man's new best friends．
What happens after an earthquake? We send in rescue（救援） dogs. Why? Because they can smell people．Dogs save lives．They help rescuers to find living people．But dogs are big and they can't get into small spaces．So now a new research project is using a smaller animal to save lives：the rat．
How does it work? First，the rat is trained to smell people．When this happens，the rat's brain gives a signal（信号）．This is sent to a small radio on its back，and then the rescuers follow the radio signals．When the rat's brain activity jumps，the rescuers know that someone is alive．The rat has smelled that person．
Although there are already robots which can do this job，rats are better．Christian Linster at Cornell University—New York says，“Robots' noses don't work well when there are other smells around．Rats are good at that．” Rats can also see in the dark．They are cheaper and quicker to train than dogs，and unlike robots，they don't need electricity!
The “rat project” is not finished，but Julie Ryan of International Rescue Corps in Scotland says，“It would be fantastic．A rat could get into spaces we couldn't get to and a rat would get out if it wasn't safe．” Perhaps for the first time in history，people will be happy to see a rat in a building（but only after an earthquake，of course）．In the world earthquake capitals，rats will become man's best friends because they can _________．
| A．take the place of man's rescue jobs |
| B．find the position of people alive who are trapped in buildings |
| C．serve as food for people alive who are trapped in buildings |
| D．get into small spaces |
From the third paragraph we know the rescuers can judge a person is alive by_________．
| A．the noise made by the rat | B．the rat's unusual behavior |
| C．the signal sent by the radio on the rat's back | D．the smell given off by the person |
In doing rescue jobs，_________．
| A．rats smell better than dogs |
| B．dogs don't need to be trained to smell people |
| C．robots' sense of smell can be affected by other smells around |
| D．rats can see in the dark and smaller than robots |
Rats have all the following advantages except that_________．
| A．they are more fantastic than other animals | B．they are less expensive to train than dogs |
| C．they don't need electricity | D．they are small and can get into small places |

Once a man named Grand found a box of old papers in a room at the top of his house. He burned most of them, because he didn’t like old things very much, But one of these papers was an old letter. At the bottom(底部) of the letter was the name of a well-known writer. “When this letter was written,” said Grant, “no one knew about the writer. But now everyone knows him. Some people like to buy letters like this. I may be able to get much money for the letter if I sell it to the right man.”
But there were a lot of dirty marks all over the letter.
“It doesn’t look nice,” he thought. “No one wants to buy a letter if it’s dirty. I’ll have to clean it.”
So he took a piece of cloth and some water and cleaned the letter. He worked hard and gave a lot of care. At last the letter looked better. And he was very pleased with his work.
“Now it looks nice,” he said to himself. “I’ll be able to sell it for a lot of money.”
He took the letter to a shop in London where old papers of this kind were bought and sold.
“I want to sell this letter,” Grant said to the man in the shop. “It was written by a well-known writer. You know about these things. How much will you give me for it?”
The man looked at him for a long time.
“I will give you two pounds for it,” he said at last.
“Only two pounds!” said Grant. “But people pay ten pounds for a letter like this. And just look! I’ve even cleaned it to make it look nice.”
“I can see that,” said the man. “That’s the trouble. People who buy old papers like them to be dirty.”Which of the following is not right?

If you do not use your arms or your legs for some time, they become weak. When you start using them again, they slowly become strong again. Everybody knows this. Yet there are many people who do not seem to know that one’s memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by exercising it regularly. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.
If a friend complains that his arms are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, or that he is just unlucky, and few of us realize that it is really his own fault. Not all of us can become very strong or very clever, but all of us can improve our memory by the same means —practice.
Have you ever noticed that people who cannot read or write usually have a better memory than those who can? Why is this? Of course, because people who can’t read or write have to remember things: they cannot write them down in a little notebook. They have to remember dates, prices, names, songs and stories, so their memory is exercised all the time.
So if you want a good memory, learn from those who cannot read or write: practice remembering. According to the passage, few people know that _____.
| A．arms or legs become weak if they are not used for some time |
| B．when they start using their arms or legs again, they slowly become strong again |
| C．a person’s memory becomes weak if he does not practice remembering things |
| D．it is their own fault if their arms or legs are weak |
The author thinks that if a person has a poor memory, ____.
| A．it is his own fault | B．his parents are to blame |
| C．he is just unlucky | D．his arms must be weak |
According to the passage, we learn that all of us can ____.
| A．become very strong | B．become very clever |
| C．improve our memory by practicing | D．know how to improve our memory |
