Question

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 become 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(子宮).

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 become 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.

Answer 1

【答案】

1.A

2.D

3.B

【解析】

試題分析：本文是關(guān)于克隆人的話題的討論，有人支持也有人反對，在文章中對于克隆人的優(yōu)點和缺點都做了詳細地說明。

1.A 推理題。根據(jù)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.說明他們希望在未來的1,2年里制造出世界上第一個克隆的嬰兒，故該詞是指A項。

2.D 推理題。文章3,4,5段中很多科學(xué)家都支持克隆人的行為，但是在文章倒數(shù)最后一段Many medical experts and other groups are opposed to the idea of cloning humans說明很多人也反對這樣的行為，故D項說法是正確的。

3.B 根據(jù)文章最后一段第二行Several countries ban or restrict work on human cloning.說明很多國家都禁止克隆人，所以說這樣做是違法的，故B正確。

考點：考查新聞報告類短文閱讀

點評：本文討論的是克隆人的話題，從題目設(shè)置的角度看，本題側(cè)重對學(xué)生把握文章中心段落和各段落的中心句的能力的考查，所以遇到這類題后，要注意把握好文章結(jié)構(gòu)，了解文章中心意思，找到各段落中心句。不要讓文中的一些生詞影響了注意力。
