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
第1题:
A. entrance
B.research
C.inquiry
D.investigation
第2题:
When Mr. Westhusin says “... cloning is dangerous,” he implies that _____.
[A] lab technicians may be affected by chemicals
[B] cats and dogs in the lab may die of diseases
[C] experiments may waste lots of lives
[D] cloned animals could outlive the natural ones
本题考查句意的理解。题干引用的话出现在第二段末。其上文即该段倒数第二句中,威斯苏森先生指出,在猫或牛的克隆试验中,对动物卵的浪费以及许多动物的自然性流产都可以接受,但是克隆人就不行。因此可知,[C]是“危险”的真正含义。其他项文中都未提及。

第13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.
本题考查考生文中人物观点。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。[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。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]部分错误。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,反对克隆人,因此[D]正确。
第14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
本题考查推理引申。第三段首句提到,克隆狗是能带来丰厚科研报酬的商机。下文无论是提到动医学院频繁接到的电话,还是举出一掷千金想克隆爱犬的富人的例子都是为了说明首句的观点。因此从第三段可推出的结论是[B]。
该段主要涉及的是克隆狗,因此无从推知[A];从该段最后两句可知,[C]与事实相反;[D]错在revive,由该段第四句可知,密斯的主人只是想要一个密斯的孪生子在它死后继承其优良品质第15题:
