Scientific experiments can sometimes go wrong and when they do the results may range from the disastrous to the troubling. One such experiment took place in South America about fifty years ago. Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen.
The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country’s bees. He imported a very active type of African bee from Tanzania and mated (交配)it with the more easy-going native variety to produce a new kind of bees. The new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, for that was the scientist's name, had a total success on his hands.
Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities. They became bad-tempered and easy to be angry, attacked the native bees and drove them from their living places.
But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings (叮) , began to attack its neighbors -- cats, dogs, horses, chickens and finally man himself. A long period of terror began that has so far killed a great number of animals and about 150 human beings.
This would have been bad enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them. The results of the South American experiment .

The experiment mentioned in this passage was designed to .

Which of the following may be the cause of the new bees' attacking personalities?
| A．Their production of honey. | B．Their living environment. |
| C．Their hard work. | D．Their bad temper. |
The last paragraph implies that .
| A．the bees have been driven to Central and North America |
| B．the bees must be stopped from moving north |

| D．the bees prefer to live in Brazil |
The Peales were a famous family of American artists. Charles Willson Peale is best remembered for his portraits of leading figures of the American Revolution. He painted portraits of Franklin and Jefferson and over a dozen of George Washington. His life-size portrait of his sons Raphaelle and Titian was so realistic that George Washington reportedly once tipped his hat to the figures in the picture.
Charles Willson Peale gave up painting in his middle age and devoted his life to the Peale museum, which he founded in Philadelphia. The world’s first popular museum of art and natural science mainly covered paintings by Peale and his family as well as displays of animals in their natural settings. Peale found the animals himself and found a method to make the exhibits more lifelike. The museum’s most popular display was the skeleton (骷髅) of a huge, extinct（灭绝的）elephant, which Peale unearthed on a New York farm in 1801.
Three of Peale’s seventeen children were also famous artists. Paphaelle Peale often painted still lives of flowers, fruit, and cheese. His brother Rembrandt studied under his father and painted portraits of many noted people, including one of George Washington. Another brother, Rubens Peale, painted mostly landscapes and portraits.
James Peale, the brother of Charles Willson Peale, specialized in miniatures (小画像). His daughter Sarah Miriam Peale was probably the first professional female portrait painter in America.

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.
1. The passage is mainly about_____________.
A. a new medical invention B. a new research on the pill

2. The drug tested on people can_____________.
A. cause the brain to fix memories
B. stop people remembering bad experiences
C. prevent body producing certain chemicals
D. Wipe out the emotional effects of memories
3. We can infer from the passage that_____________.
A. people doubt the effects of the pills
B. the pill will stop people's bad experiences
C. taking the pill will do harm to people's health
D. the pill has probably been produced in America
4. Which of the following does Rebecca Dresser agree with?
A. Some memories can ruin people's lives.
B. People want to get rid of bad memories.
C. Experiencing bad events makes us different from others.

Have you ever seen people dance? Some dances are fast and others are slow. People’s feet always move when they dance. They keep on moving until the music stops.
People have enjoyed dancing for a very long time. This story is of a different kind of dance. It is a dance without people or music. Yet this dance is one of the oldest in the world. It is the dance of bees.
If you have ever watched bees, you know that they are very clever. They also work hard looking for food and bringing it back to their home.
The home of the bees is called a bee hive. Here hundreds even thousand of bees live. They work day and night building small walls. There they make their honey. This is the same honey that we eat.
Where does the honey come from? Bees live on food from flowers. Have you seen bees flying around a flower garden? When a bee rests on a flower, it tries to go to the centre of it. There it takes in as much food as its body can hold. Then it flies to take the food back to the hive.
At the hive, bees change flower food into honey. Then they fly away for more food.
How do the bees know where to find the best food in the sweetest flowers? One bee acts as a guide. When it discovers good flowers, it flies back to the hive and tells the others. It does this by dancing for them.
The bee dances on one side. This tells the other bees which way to go to find the flowers. But that is not all. The bee dances for some time. And the length of its dance tells the other bees how far they must fly to reach the flowers.
When the bees see the dance, they know where the flowers are. They fly away and return with more food for the hive.
Sometimes we hear the music of the bees as they fly around. But few people have ever seen them dance. Yet without that dance we might never have sweet honey to eat.

Most Americans enjoy moving from place to place. For example, they often drive their cars 120 to 160 kilometers away just to have dinner with a friend or even fly to Europe just for watching a football match. In some states only one person in five lives in a place for more than five years. One may be born in one city, and go to school in another. He may finish his middle school in two or three cities, and then attend a college far across the country. When he has entered business, he may possibly move from job to job. Moving from one job to another, which is called “job-hopping”, is a very common practice in the United States. Job-hopping is good to workers, because every change of a job gives them a chance to move up to a higher position and to get better pay. And job-hopping also gives bosses the chance to get new ideas and skills that different people bring to their companies and factories.
