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 wipe out, 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 wiped out. They are not sure to what degree people’s memories are affected.

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 maybe the pills can change people’s memories and 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 terrible 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 invention

B. a new research on the pill

D. an argument about the research on the pill

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

We can infer from the passage that .

A. people doubt the effects of the pills

B. the pill will certainly stop people's emotional memories

C. taking the pill will do harm to people's physical health

D. the pill has already been produced and used by the public in America

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.

D. the pill will reduce people's sufferings from bad memories.

In the United States you will find yourself being urged from every page of every newspaper and every television station to buy all kinds of goods.

Not only is there a wide range of prices for goods in America, there is also a wide range in the quality of goods offered for sale. Unlike some countries, Americans generally pay the price of a product without question, instead of trying to get a lower price by bargaining. However, there are many “sales” in the United States, during which time stores will lower their normal prices. This may all be very confusing to visitors. How are you going to know how to “get your money’s worth” when you shop? Perhaps the best advice is: Don’t hurry. Visit various stores and determine the quality of goods. Read the advertisements so that you can compare prices.

There is a great variety of shops in the United States, ranging from very large stores called “department stores” to very small shops. There are “discount houses” offering goods at low prices, and “dime stores” specializing in a wide range of inexpensive items.

Most department stores in large cities carry better quality products at higher prices. However, they offer the shoppers great convenience since they contain such a wide variety of products.

If convenience isn’t as important to you as price, you may want to shop in discount houses. These stores have nearly as great a variety of goods as department stores, but offer lower prices. They can do so for several reasons. They don’t offer the same services to buyers that department stores do; there may be fewer sales people; and the store probably doesn’t deliver purchases.

Another popular shop is the “dime store”. No longer selling many things for five or ten cents, these stores got their name in the last century when it was decided that a small profit on a great quantity of goods would be better than a large profit on fewer sales. Dime stores specialize in a wide variety of inexpensive items and today, prices range from a quarter or 50 cents up to several dollars.

1.Where can we most probably read this passage?

A. In a research paper. B. In a science report.

C. In a geography book. D. In a travel magazine.

2.Why can discount houses offer goods at lower prices compared with department stores?

a. They have fewer employees.

b. They have larger quantities of goods.

c. They offer fewer services.

d. They don’t provide delivery service.

A. a b c B. a b d C. a c d D. b c d

3.What’s special about dime stores?

A. They sell lots of goods at a small profit.

B. They make big profits by selling some goods.

C. They provide goods with a price lower than 50 cents.

D. They provide goods ranging from bargains to expensive ones.

Many people watched the lift-off of the space shuttle Columbia on March 21, 1982. But none watched more closely than eighteen-year-old Ted, as Ted’s insects were on board the shuttle.

The Shuttle Student Involvement Program invited students to make a science experiment. The experiment would be done by astronauts on the space shuttle.

Ted had always been interested in space and flight. Insect flight especially interested him. Ted noticed that insects need gravity to take off and land. They need gravity to fly in a straight line. But in space, there is no gravity. Could insects fly in zero gravity? That is what Ted wanted to find out.

Ted made an experiment called “Insect in Flight Motion Study”. He entered his experiment and soon news came that it was a winner.

A large team of scientists and engineers helped Ted get his experiment ready to fly. There were many questions to be answered first. What kind of insects would Ted use in his experiment? The insects would have to be strong enough to live on the shuttle for nine days without much food. What kind of container would hold the insects? Would the insects die during the shuttle flight?

After months of hard work, the “insectronauts” were chosen. A group of moths, flies, and honeybees were put into a special box and put onto the space shuttle. When Columbia flew into space, it was carrying insect passengers.

On March 24, astronauts Gordon Fullerton and Jack Lousma took out the box that held the insects. They began filming the insects with a special video camera.

When the space shuttle landed Ted was able to watch the video film of insects. Just as he thought, most of the insects did have trouble flying in zero gravity. The flies did well. But the moths’ flight seemed “uncontrolled”. They would often just hang in the air. The bees had the most trouble. They couldn’t fly at all! The film showed bees spinning around in all directions. Others were just floating about in the box.

Ted learned the answer to his question about insects’ flight in zero gravity. But he also learned a lot more. He learned about the hard work needed in making a successful experiment.

1.What does the underlined sentence “it was a winner” mean?

A．Ted could fly in space. B．Ted won a prize.

C．Ted’s experiment was accepted. D．Ted won in a race.

2.What did Ted want to find out?

A．Whether the insects could fly in space.

B．Whether the insects could fly in a straight line.

C．Whether the insects could land after flying for a while.

D．Whether the insects could take off after resting for a while.

3.Of the three kinds of insects sent into space, which one flew worst in zero gravity?

A．The flies. B．The honeybees. C．The insects. D．The moths.

4.Who did the experiment?

A．Ted himself.

B．Ted’s friend.

C．A large team of scientists and engineers.

D．Two astronauts on the space shuttle.

5.How did Ted learn the answer to his question about insects’ flight in zero gravity?

A．By asking the scientists and engineers.

B．By studying a book written by the astronauts.

C．By going into space and watching the insects’ flight himself.

D．By watching the video film made by the astronauts.
