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

The Food and Drug Administration says meat and milk from clones of adult animals are safe to eat. They called them “as safe to eat as the food we eat every day.” And when those clones reproduce sexually(有性繁殖), the agency says, their offspring(后代)are safe to eat as well.

The United States this year could become the first country to allow the sale of foods from cloned animals. First，however，the public will have ninety days to comment on three proposed documents. On December 28th the F.D.A. released a long report, called a draft risk assessment, along with two policy documents. The agency says it must receive comments by April 2nd. The F.D.A. seemed ready to act several years ago，but an advisory committee called for more research.

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

Clones are still rare. They cost a lot and are difficult to produce. The F.D.A. 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 know little about cloning. Cloning differs from genetic engineering. A cell taken from a so­called 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 its full term and a genetic copy of the donor animal is born.

1. From the passage, we know ________.

A. the US government is very cautious about the safety of cloned foods

B. foods from cloned animals are popular in America

C. cloned animals will be easy to produce

D. most foods from cloning are expected to come from clones themselves

2.Who believes that foods from cloning are safe to eat?

A. Most Americans.　　 B. An advisory committee.

C. Critics.　　 　　　　 D. The F.D.A. .

3. It can be inferred from the last paragraph that _______.

A. cloning has much in common with genetic engineering

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

4. Whether the sale of cloned foods is allowed in the US depends on ________.

A. cloning technology

B. the advisory committee’s research

C. public comments

D. the documents of the F.D.A.

The United States government wants to know what the public think 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 F.D.A. official called them "as safe to eat as the food we eat every day." And when those clones reproduce sexually (有性繁殖), the agency says, their offspring (后代) are safe to eat as well. But research on cloned sheep is limited. So the F.D.A. suggests that sheep clones not be used for human food.

The United States this year could become the first country to approve the sale of foods from cloned animals. First, however, the public will have ninety days to discuss three proposed documents.
