题目内容

Cloning is suggested as a means of bringing back a relative, usually a child, killed tragically. Some parents can understand that wish, but it must first be recognized that the copy would be a new baby and not the lost child. Here lies the difficulty, for the sad parents are seeking not a new baby but a return of the dead one. Since the original would be fondly remembered as having particular talents and interests, would not the parents expect the copy to be the same? It is possible, however, that the copy would develop quite differently. Is it fair to the new child to be placed in a family with such unnatural expectations?

Copying is also suggested as a means by which parents can have the child of their dreams. Couples might choose to have a copy of a film star, baseball player or scientist, depending on their interest. But because personality is only partly the result of genetic inheritance(遗传), conflicts would be sure to arise if the cloned child failed to develop the same interests as the original. What if the copy of Einstein shows no interest in science? Or the baseball player turns to acting? Success also depends upon fortune. What if the child does not live up to the hopes and dreams of the parents simply because of bad luck?

Every child should be wanted for itself, as an individual. In making a copy of oneself or some famous person, a parent is deliberately（深思熟虑地） specifying(详细说明) the way he or she wishes that child to develop. In recent years, particularly in the U.S., much importance has been placed on the right of individuals to reproduce in ways that they wish. So I suggest there is a greater need to consider the interests of the child and to reject these proposed uses of cloning.

40. What happens to parents in cloning a lost child?

A. Parents expect too much from the copy.

B. Parents may get a quite different copy.

C. Parents are sure to have an identical copy.

D. Parents lose the talents of the lost child.

41. What, in the author’s opinion, affects the success of parents’ dreams?

A. The cloned child’s interest in Einstein.

B. The cloned child’s natural talent.

C. The cloned child’s personality.

D. The efforts of the parents.

42. In the third paragraph, the author implies that ______.

A. the cloned child is viewed as independent

B. the right of growing in his own way is taken away from the cloned child

C. parents carefully protect the rights of the cloned child

D. parents are eager to wish the cloned child to be somebody.

43. In this passage, the author is mainly concerned about ______.

A. the future of a cloned child

B. the possibility of cloning people

C. the importance of cloning a lost child

D. the problems of cloning life

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 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. proposes 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 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 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.

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 knows little about cloning.

Cloning differs from genetic engineering. A cell taken from a so-called donor animals 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.

From the passage we know that .

A. foods from cloned animals are popular in America

B. cloned adult animals are safe to eat except sheep.

C. cloned animals will be easy to produce

D. most foods from cloning is expected to take place of other foods

The main purpose of the text is to .

A. tell a interesting story B. give some advice on foods

C. give a report D. compare different opinions

Who believe that foods from cloning are safe to eat?

A. Most Americans B. An advisory committee

C. Critics D. The F.D.A.

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

D．The author is quite excited about human cloning.

Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene（基因）is complete. Couple of years ago, this seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away. Human cloning has always been a topic of argument，in terms of morality or religion.

Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. If the clone was free of genetic limitations. Then the other clone would be as well. The latter could foe inserted in the woman and allowed to ripen to term. Moreover，cloning would enable women, who can’t get pregnant, to have children of their own.

Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single(or more) organ(s）.It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.

Arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal “cycle”of life. There would be a large number of same genes., which reduce the chances of improvement，and, in turn, development-the fundamental reason how living things naturally adapt to the ever-changing environment. Life processes failing to do so might result in untimely disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappea. Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would be regarded as “objects” rather than people in the society.

Scientists haven’t 100 percent. guaranteed that the first cloned will be normal. Thus this could result in introduction of additional limitations in the human “gene-pool”.

Regarding such arguable topics in “black or white” approach seems very innocent to me personally. We should rather try to look at all “shades: of it. I believe that cloning is only legal if its purpose is for cloning organs, not humans. Then we could regard this as for “saving life” instead of “creating life”. I believe cloning humans is morally and socially unacceptable.
