09考试中心六套题第一套(编辑修改稿)内容摘要：

points) Text 1 “ I’ve never met a human worth cloning,” says cloning expert Mark Westhusin from the cramped confines of his lab at Texas Aamp。 M University. “ It’s a stupid endeavor.” That’s an interesting choice of adjective, ing from a man who has spent millions of dollars trying to clone a 13yearold dog named Missy. So far, he and his team have not succeeded, though they have cloned two calves and expect to clone a cat soon. They just might succeed in cloning Missy later this year— or perhaps not for another five years. It seems the reproductive system of man’s best friend is one of the mysteries of modern science. Westhusin’s experience with cloning animals leaves him vexed by all this talk of human cloning. In three years of work on the Missyplicity project, using hundreds upon hundreds of canine eggs, the Aamp。 M team has produced only a dozen or so embryos carrying Missy’s DNA. None have survived the transfer to a surrogate mother. The wastage of eggs and the many spontaneously aborted fetuses may be acceptable when you’re dealing with cats or bulls, he argues, but not with humans. “ Cloning is incredibly inefficient, and also dangerous,” he says. 沪江考研 15 Even so, dog cloning is a mercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1997, Westhusin’s phone at Aamp。 M College of Veterinary Medicine has been ringing busily. Cost is no obstacle for customers like Missy’s mysterious owner, who wishes to remain unknown to protect his privacy. He’s plopped down $ million so far to fund the research because he wants a twin to carry on Missy’s fine qualities after she dies. But he knows her clone may not have her temperament. In a statement of purpose, Missy’s owners and the Aamp。 M team say they are “ both looking forward to studying the ways that her clone differs from Missy.” The fate of the dog samples will depend on Westhusin’s work. He knows that even if he gets a dog viably pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems. “ Why would you ever want to clone humans,” Westhusin asks, “ when we’re not even close to getting it worked out in animals yet?” 1. 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. 沪江考研 16 ［ D］ Animals cloning yes, and human cloning at least not now. 2. 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 plicated 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 3. 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 4. 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 being 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 5. We may conclude from the text that _____. ［ A］ human cloning will not succeed unless the technique is more efficient 沪江考研 17 ［ 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 答案 1. D 总体分析 本文是一篇讨论克隆动物和克隆人实验的文章。 第一段：引用专家的话指出克隆人是愚蠢的尝试，接着提到正在进行的克隆动物的实验，指出狗的克隆最具有难度。 第二段：介绍动物克隆实验所反映出来的低效性使威斯苏森教授反对克隆人。 第 三段：转折指出，但是克隆狗存在巨大的商机。 第四段：指出克隆动物还远没有成功，并再次引用专家的话否认目前克隆人的可行性。 试题精解。 ［ A］ 克隆动物是一种愚蠢的尝试。 ［ B］ 克隆人还没有接近成功。 沪江考研 18 ［ C］ 克隆的效率太低，应该被禁止。 ［ D］ 克隆动物可以，克隆人至少现在还不行。 ［精解］ 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。 2. 克隆密斯项目似乎不是非常成功，原因可能是 _____。 ［ A］ 没有足够的资金支持这项研究 ［ B］ 克隆狗比克隆猫或牛更复杂 ［ C］ 威斯苏森先生太忙于照料生意 ［ D］ 狗的主人要求和他的宠物一模一样的复制品 ［精解］ 本题考查事实细节。 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。 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，高额的花沪江考研 19 销并不是什么障碍。 由此可知，［ A］不是项目不成功的原因。 ［ C］属于无中生有项，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。 3. 当威斯苏森先生说“克隆是危险的”，他的意思是 ______。 ［ A］ 实验室的技术员可能会受到化学物质的感染 ［ B］ 实验室里的猫和狗可能死于疾病 ［ C］ 实验会浪费很多生命 ［ D］ 克隆的动物比一般的动物能活得更长 ［精解］ 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。 4. 从第三段我们可以推知 ______。 ［ A］ 富人对克隆人比对克隆动物更感兴趣 ［ B］ 克隆动物宠物正成为一个欣欣向荣的产业 ［ C］ 克隆狗和一般的狗之间没有什么区别 ［ D］ 密斯的主人出重金希 望狗能复活 沪江考研 20 ［精解］ 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。 5. 从文章中我们可以得知 ________。 ［ A］ 除非技术效率提高否则克隆人类不会成功 ［ B］ 科学家们对克隆技术持乐观态度 ［ C］ 许多人反对克隆人的想法 ［ D］ 克隆的动物即使弱小也更受主人青睐 ［精解］ 本题考查全局事实细节题。 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。
