A private group of scientists has announced plans to make an exact copy of a human being. An American member of the team says he and the others will soon begin a serious effort to clone humans. Panos Zavos says the team hopes to manufacture the world’s first cloned baby within the next two years.
In recent years, scientists have produced exact genetic copies of sheep and a few other animals. They created these clones from a single cell of an adult animal.
Three years ago, another American doctor, Richard Seed, announced plans to clone a human being. However, there is no evidence that he has been successful.
Doctor Zavos says the new international group plans to offer human cloning only to women who are currently not able to bee pregnant or produce children. He says the aim is to assist people who want to have their own biological child.
The technology would be similar to that used to clone animals. It would involve cleaning genetic material from a woman’s egg. Doctors then would place genetic material from the woman’s husband into the egg before putting it into the woman’s uterus(子宫).
Doctor Zavos says his group plans to do the work in a country near the Mediterranean Sea. He did not name the country. He says an Italian reproductive expert, Sevorino Antinori, is leading the team. Doctor Antinori has led the efforts to help many older women bee pregnant. He is known for establishing pregnancies in women as old as sixty.
Many medical experts and other groups are opposed to the idea of cloning humans. Several countries ban or restrict work on human cloning. Several doctors criticize the announcement by Doctor Zavos. They say doctors do not know if cloning humans is possible or safe. They say it would be irresponsible to attempt to clone a human being. That is because the chances of success are too small and the risks are too great.

(答案→)A
解析：本文是关于克隆人的话题的讨论，有人支持也有人反对，在文章中对于克隆人的优点和缺点都做了详细地说明。
【小题1】A 推理题。根据第一段最后一句Panos Zavos says the team hopes to manufacture the world’s first cloned baby within the next two years.说明他们希望在未来的1,2年里制造出世界上第一个克隆的婴儿，故该词是指A项。
【小题2】D 推理题。文章3,4,5段中很多科学家都支持克隆人的行为，但是在文章倒数最后一段Many medical experts and other groups are opposed to the idea of cloning humans说明很多人也反对这样的行为，故D项说法是正确的。
【小题3】B 根据文章最后一段第二行Several countries ban or restrict work on human cloning.说明很多国家都禁止克隆人，所以说这样做是违法的，故B正确。
