In an ideal world，people would not test medicines on animals. Such experiments are stressful and sometimes painful for animals，and expensive and time­consuming for people. Yet animal experimentation is still needed to help bridge vast gaps in medical knowledge. That is why there are some 50 to 100 million animals used in research around the world each year.

Europe，on the whole，has the world’s most restrictive(严格的) laws on animal experiments. Even so，its scientists use some 12 million animals a year，most of them mice and rats，for medical research. Official statistics show that just 1.1 million animals are used in research in America each year. But that is misleading. The American authorities do not think mice and rats are worth counting and，as these are the most common laboratory animals，the true figure is much higher. Japan and China have even less comprehensive（全面的） data than America.

Now Europe is reforming the rules governing animal experiments by restricting the number of animals used in labs. Alternatives to animal testing，such as using human tissue or computer models，are now strongly recommended. In addition，sharing all research results freely should help to reduce the number of animals for scientific use. At present，scientists often share only the results of successful experiments. If their findings do not fit the hypothesis（假设） being tested，the work never sees the light of day. This practice means wasting time，money，and animals’ lives in endlessly repeating the failed experiments.

Animal experimentation has taught humanity a great deal and saved countless lives. It needs to continue，even if that means animals sometimes suffer. Europe’s new measures should eventually both reduce the number of animals used in experiments and improve the way in which scientific research is conducted.

1.What is the main idea of this passage?

A. The success of animal experiments should be ensured.

B. A ban on the use of animals in the lab should be enforced.

C. Greater efforts need to be taken to reduce the number of lab animals.

D. Scientists should be required to share their research results with each other.

2.Which of the following statements is true about animals used in the lab?

A. America uses only about 1.1 million lab animals per year.

B. Europe does not use mice and rats as lab animals at all.

C. Britain does not use as many lab animals as China does.

D. Japan has limited data on the number of lab animals used each year.

3.Which of the following is mentioned as an alternative to replace animal experiments?

A. Statistical studies.　　　　　 B. Computer models.

C. DNA planted in animals.　　　 D. Tissue from dead animals.

4.What usually happens to unsuccessful animal experiments?

A. They are not made known to the public.

B. They are made into teaching materials.

C. They are collected for future publication.

D. They are not removed from the research topic list.

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.

47. The passage is mainly about _________.

A. a new medical invention

B. a new research on the pill

C. a way of erasing painful memories

D. an argument about the research on the pill

48. 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

49. 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

50. 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.

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