第1题：

We can infer from the third paragraph that .

［A］ rich people are more interested in cloning humans than animals

［B］ cloning of animal pets is becoming a prosperous industry

［C］ there is no distinction between a cloned and a natural dog

［D］ Missy’s master pays a lot in a hope to revive the dog


正确答案：B
推理题。第三段首句提到，克隆狗是能带来丰厚科研报酬的商机。下文举了两个例子进一步说明：动物医学院频繁接到电话，以及富人一掷千金想克隆爱犬，因此可以推出答案是［B］ 。［A］ 项文中没有提及，［C］与文意相反，［D］项原文中密斯的主人只是想要一个密斯的孪生子，而不是让密斯死后复活。

第2题：

If cloned animals could be used as organ donors, ().

A、people don’t have to worry about cloning twins for transplants

B、raising animals such as pigs can help solve the problem

C、the human body attacks and destroys tissue from other species

D、it may be more efficient to produce such animals by cloning than by cur


参考答案：ABD

第3题：

Which of the following best represents Mr.Westhusin’s attitude toward cloning?

［A］ Animal cloning is a stupid attempt.

［B］ Human cloning is not yet close to getting it worked out.

［C］ Cloning is too inefficient and should be stopped.

［D］ Animals cloning yes, and human cloning at least not now.


正确答案：D
观点态度题。文中多次引用了威斯苏森先生有关克隆的话，从中我们可以判断出他的态度。［A］ 中a stupid attempt出现在文章开始部分，是他对于克隆人而非克隆动物的看法，因此［A］ 错误。［B］ 中not yet close to getting it worked out出现在文章末句，是他对待动物实验的看法，不包括克隆人，因此也不选［B］ 。事实上，克隆人还没有开始，谈不上是否接近成功。第二段末句，威斯苏森先生提到克隆是极其低效的，但没有提出因此就应该被禁止。因此，［C］也错误。第二段倒数第二句，威斯苏森先生提出，动物实验中对动物卵的浪费以及动物的自然性流产还可以接受，但研究人就不行。可见，他默许克隆动物，但他反对克隆人，因此［D］ 正确。

Cloning（克隆）:Future Perlect?

1 A clone is an exact copy of a plant or animal produced from any one cell.Since Scottish
scientists reported that they had managed to clone a sheep named Dolly in 1997,research
into cloning has grown rapidly.In May 1998,scientists in Massachusetts managed to
create two identical calves（牛犊）using cloning technology. A mouse has also been
cloned successfully.But the debate over cloning humans really started when Chicago
physicist Richard Seed made a surprising announcement:"We will have managed to clone
a human being within the next two years."he told the world.
2 Seed's announcement provoked a lot of media attention,most of it negative,In Europe,
nineteen nations have already signed an agreement banning human cloning and in the
U.S. the President announced:"We will be introducing a law to ban all human cloning and
many states in the U. S. will have passed anti-cloning laws by the end of the year."
3 Many researchers are not so negative about cloning.They are worried that laws banning
human cloning will threaten important research.In March,The New England Journal of
Medicine called any plan to ban research on cloning humans seriously mistaken.Many
researchers also believe that in spite of attempts to ban it,human cloning will have become
routine by 2010 because it is impossible to stop the progress of science.
4 Is there reason to fear that cloning will lead to a nightmare world?The public has been
bombarded（轰炸）with newspaper articles, television shows and films, as well as
cartoons.Such information is often misleading,and makes people wonder what on earth
the scientists will be doing next.
5 Within the next five to ten years scientists will probably have found a way of cloning
humans.It could be that pretty soon we will be able to choose the person that we want our
child to look like,But how would it feel to be a clone among hundreds,the anti-cloners
ask. Pretty cool, answer the pro-cloners（赞成克隆的人）.

Within ten years scientists wil!probably have_______.
A:the nucleus of a cell
B:cloned human beings
C:a human being in two years
D:a law to ban human cloning
E:a report on human cloning
F:heavy media coverage

答案：B
解析：

第5题：

A group of scientists are conducting a(_______)into the feasibility of cloning human beings.

A. entrance

B.research

C.inquiry

D.investigation


参考答案：B

第6题：

We may conclude from the text that .

［A］ human cloning will not succeed unless the technique is more efficient

［B］ scientists are optimistic about cloning technique

［C］ many people are against the idea of human cloning

［D］ cloned animals are more favored by owners even if they are weaker


正确答案：A
细节题。文章一开始就引用专家威斯苏森的话，指出克隆人是愚蠢的尝试。第二段最后两句提到，克隆实验的低效性和危险性在克隆人中不可接受。文章末尾再次引用该专家的话，指出现在动物的克隆研究还没完全成功，没有必要想到克隆人。由此可见，技术是克隆实验存在的主要问题，也是阻碍克隆人实验的重要原因，因此可推知［A］ 正确。［B］ 明显错误，科学家并不乐观。全文只涉及专家和拥护克隆实验的人的观点，因此无法推知［C］ 中的“许多人”。［D］ 在文中没有提及。

第7题：

Why do some people oppose cloning?()

A.It is not perfect

B.It is against our traditional ethics and morality

C.It is against the natural law

D.It may devaluate real life


正确答案：ABCD

第8题：

The Missyplicity project does not seem very successful probably because .

［A］ there isn’t enough fund to support the research

［B］ cloning dogs is more complicated than cloning cats and bulls

［C］ Mr.Westhusin is too busy taking care of the business

［D］ the owner is asking for an exact copy of his pet


正确答案：B
细节题。第一段倒数第二句指出，克隆密斯可能成功也可能失败。该段最后一句解释其原因是：狗的生殖系统似乎是现代科学中一个神秘的领域，可见克隆狗更复杂。因此［B］ 为正确项。第三段首句提到，克隆狗是一个商机，能带来丰厚的科研报酬。该段第三句又提到，对于像密斯的主人这样的消费者来说，高额的花销并不是什么障碍。由此可知，［A］不是项目不成功的原因。［C］ 原文没有提及，第三段第二句只提到，多利羊克隆成功后，威斯苏森教授接到很多希望克隆狗的电话，这些电话都潜藏商机。但不能由此推知他忙于商业活动。第三段最后两句提到，密斯的主人知道，密斯的克隆体不一定能有与它一样的脾气秉性。在一份用途声明中，密斯的主人和农业机械大学的团队表示，他们“共同期待能研究密斯的克隆体与它本身的差异之处。”可见［D］ 也不是原因。
