The United States government wants to know what the public thinks about its findings on the safety of cloned animals.

The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat. An FDA official called them “as safe to eat as the food we eat every day.” And when those clones reproduce sexually, the agency says, their offspring (后代) are safe to eat as well. But research on cloned sheep is limited. So the FDA proposes that sheep clones not be used for human food.

The United States this year could become the first country to agree to the sale of foods from cloned animals. First, however, the public will have ninety days to comment on three suggested documents. On December 28th the FDA released a long report, called a draft risk assessment, along with two policy documents.

The agency says it must receive comments by April second. The FDA seemed ready to act several years ago, but a committee called for more research.

For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals.

Clones are still rare. They cost a lot and are difficult to produce.

The FDA says most food from cloning is expected to come not from clones themselves, but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities.

Public opinion studies show most Americans do not like the idea of food from cloned animals. But this research also shows the public knows little about cloning.

Cloning differs from genetic engineering. A cell taken from a so-called donor animal is grown into an embryo (胚胎) in the laboratory. Next, the embryo is placed into the uterus (子宫) of a female animal. If the process is successful, the pregnancy reaches full term and a genetic copy of the donor animal is born.

 

41. What’s the main purpose of the passage?

A. To tell an interesting story.                    B. To give some advice on foods.

C. To give a report.                                  D. To compare different opinions.

42. Who believe that foods from cloning are safe to eat? __________

A. Most Americans      B. An advisory committee      C. Critics        D. The FDA

43. It can be inferred from the last paragraph that_____.

A. cloning has much in common with genetic

B. not every cell taken from a donor animal can grow into a genetic copy

C. the donor animal should be a female one

D. cloned animals grow faster than normal ones

44. Which of the following is true about foods from cloning? _______________

A. They come from the sexually reproduced offspring of cloned animals.

B. The food from first-generation cloned animals is very expensive.

C. Only FDA has the right to sell the food.

D. They will be sold mixed with those from naturally bred animals.

Jeanne Calment, a French woman, become a record breaker on 17 October 1995, when at the age of 120 years and 238 days, she became the longest-lived human being on record. A Japanese man died in 1986 at the age of 120 years and 237 days.

Jeanne Calment lives in a small old people’s home in the south of France, her husband, her only child and her grandson have all died. She is nearly blind and deaf and is always in a wheelchair, but her doctor describes here as being “more like a 90-year-old in good health” than someone of 120. She still has a lively sense of humor. When asked on the 120th birthday what she expected of the future, she replied, “A very short one.” She also remarked that she thought the good Lord had forgotten all about her.

So what is the key to a long life? According to some doctors, diet, exercise and no smoking are the three important factors. Jeanne Calment has followed two of the tips. She has always eaten a healthy diet, and she used to do exercises every day until she broke her leg at the age of 115. However, until recently she drank two glasses of strong red wine a say, and she does smoke (now only a little). Besides, Jeanne Calment might have got very good genes from her parents. Her father lived to the age of 94 and her mother to 86.

A local lawyer bought her house when she was 80 under an agreement that he would pay her some money every year until her death. It must have seemed a good move at the time, but so far the lawyer has paid her at least three times the value of the house. Every year on her birthday Jeanne Calment sends him a card saying: “Sorry, I’m still alive!”

1. How does Jeanne Calment feel about her old age?

A.She feels upset and unhappy.

B.She is cheerful and humorous.

C.She likes to live much longer.

D.She feels she is going to die very soon.

2. The text seems to suggest that Jeanne Calment owes her good health and long life to______.

A.smoking only little every day

B.neither smoking nor drinking

C.always drinking two glasses of strong red wine a day and never smoking

D.the good genes from her parents, a healthy diet and some exercises

3. Which of the following could best explain the underlined word “genes” in the third paragraph?

A.good habits of body-building.

B.Some materials that control the development of a living thing.

C.Comfortable living conditions.

D.Something necessary for a person to keep his life.

4.Why did Jeanne Calment say “Sorry, I’m still alive!” to the local lawyer?

A.She had an agreement with the lawyer when she was 80.

B.The lawyer has not paid her enough rent yet.

C.The lawyer has paid her more money than the value of the house.

D.The house she sold to the lawyer was worth the money already paid.
