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. 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 the public’s opinion by April second. 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 not sell foods from cloned animals.

In the United States, when one becomes rich, he wants people to know it. And even if he does not become very rich, he wants people to think that he is. That is what "keeping up with the Joneses" is about. It is the story of someone who tried to look as rich as his neighbors.

The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began eaming  $  125 a week at the age of 23.

When he saw that rich people rode horses, Momand went horseback riding every day. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors.

It was like a race, but one could never finish his race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They moved back to an apartment in New York City.

He called it  " Keeping up with the Joneses"  because "Jones"  is a very common name in the United States. " Keeping up with the Joneses" came to mean keeping up with rich lifestyle of the people around you. Momand's series appeared in different newspapers across the country for over 28 years.

People never seem to get tired of keeping up with the Joneses. And there are "Joneses" in every city of the world. But one must get tired of trying to keep up with the Joneses because no matter what one does,  Mr. Jones always seems to be ahead.

高二英语单项填空中等难度题查看答案及解析

In 1999, twelve percent of public elementary schools in the United States required students to wear uniforms. Just three years later, the amount was almost double that.

A study of six big-city Ohio public schools showed students who were required to wear uniforms had improved graduation, behavior and attendance rates. Academic performance was unchanged.

Some high schools in Texas have also joined in the movement. Yet studies find mixed results from requiring uniforms. And some schools have turned away from such policies.

Supporters believe dressing the same creates a better learning environment and safer schools. The school district in Long Beach, California, was the first in the country to require uniforms in all elementary and middle schools. The example helped build national interest in uniforms as a way to deal with school violence and improve learning.

Findings in Long Beach suggested that the policy resulted in fewer behavior problems and better attendance. But researcher Viktoria, who has looked at those findings, says they were based only on opinions about the effects of uniforms.

She says other steps taken at the same time to improve schools in Long Beach and statewide could have influenced the findings. The district (the area marked by government) increased punishments for misbehavior. And California passed a law to reduce class sizes.

In Florida, for example, researcher Sharon found that uniforms seemed to improve behavior and reduce violence. In Texas, Eloise found fewer discipline problems among students required to wear uniforms, but no effect on attendance.

Sociologist David has studied school uniform policies since1998．He collected the reports in the book. In his own study, he found that reading and mathematics performance dropped after a school in Pennsylvania(宾夕法尼亚州) required uniforms.

Political and community pressures may persuade schools to go to uniforms to improve learning. But David and others believe there is not enough evidence of a direct relationship. In fact, he says requiring uniforms may even increase discipline problems.

1.Which of the following researchers are NOT supporters of school uniform policies?

A.Viktoria and Sharon. B.Sharon and David.

C.Eloise and Sharon. D.Viktoria and David.

2.The underlined word“misbehavior”in the sixth paragraph probably means ________.

A.serious crime B.bad performance

C.absence for class D.action against wearing uniforms

3.What can we infer from the passage?

A.More work is needed to get better information about uniform’s effect.

B.The number of schools requiring uniforms in the U.S. will become less sharply.

C.Wearing uniforms has little to do with behavior and learning.

D.Politicians and communities won’t vote for uniform policies.

4.What’s the main idea of this passage?

A.More and more students are required to wear uniforms in the U.S.

B.Wearing uniforms contributes to good academic performance.

C.Researchers in the U.S. argue for school uniform policies.

D.Evidence for school uniform polices in the U.S. is seen as weak.
