题目内容
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 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

试题分析: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。
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。
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。
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。
考点:考查新闻报告类短文阅读

A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.
A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.
P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.
Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.
The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters are not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.
The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.
The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.
