    The Mystery of Clones

    Scientists have cloned goats,cats,cows,pigs and mice.Now it has been suggested by many commentators and scientists that it might be ethically acceptable to clone existing people in certain cases.One possibility is generating a replacement for a dying relative.All such possibilities,however,makes more and more people concerned that it would be possible that the clone is subjected to expectations and limitations based on the family's knowledge of the genetic"twin",so he or she would not be treated as an individual with independent personality.For the reason that human personality is only partly determined by genes,those assumptions might not be right.The clone of a shy person might behave quite differently if he or she is brought up in a family with encouraging atmosphere.Clones of writers,scholars,scientists or athletes are very likely to choose different careers because of chance event in early life.
    Some researchers have suggested the idea that couples,in which one part is infertile,might choose to make a copy of one or the other partner. But the notion raises the concerns that the child who is a copy of just one of a couple might not treat naturally,and it is not in the interests of the resulting kid.Moreover,the treatments of all known types of infertility are available nowadays;conventional therapies seem more ethnically acceptable to ordinary people's way of thinking,so the majority of population strongly opposed to allowing cloned human embryos(胚胎)to develop.
    However,the positive side of the cloning technology cannot be denied,for instance,cloning from cultured cells will provide essential medical opportunities.Scientists are trying to grow an embryo,cloned from a single cell of a human being with goals to design therapies for diseases which are currently untreatable.
    Of course,people's predictions about this new technology might be all wrong,because social attitudes change and unexpected developments take place.Only time will tell.But biomedical researchers who are dedicated to finding the potential of cloning have plenty to do.Maybe someday soon,a human will be cloned,and mankind will embark on a scientific and moral journey whose destination is not under his own control. Or maybe one day you will be happy to have a clone of your own.

    What is people's concern about cloning a child for infertile couples?
    A:The child might not be treated kindly.
    B:It's not for the good of the resulting child.
    C:The couples would not accept the resulting child.
    D:It would be wild to have a clone of one's own.

    答案:B
    解析:
    从文章第一段的第五句“human personality is only partly determined by genes”可以看出人类的性格只是部分由基因决定。接着又说一个害羞的人的克隆人若成长于一个拥有激励氛围的家庭,那么也可能会表现得截然不同,所以所处的环境也对人的性格产生影响。由此可以判断A正确。
    第二段第二句谈到被克隆出的孩子可能不会被父母以自然的方式对待, "it is not in the interests of the resulting kid",所以选B,意为“这对孩子没有好处”,not good for 和文中的not in the interests of意思一样。
    第三段提到克隆的积极面也不可否定,如“design therapies for diseases which are currently untreatable",所以选D。
    综观全文,作者提到了人们对于克隆技术的担心,也谈到克隆技术的积极面,所以作者态度是客观的、中立的(neutral:中立的),而不是赞同的(approved)或是不赞同的(disapproved)。
    最后一段说到人们对这个新技术的预测可能都是错的,所以“Only time will tell",没有人能真正知道克隆技术的未来如何,只有随着时间的流逝,克隆技术所带来的影响才能逐一显现出来,所以A正确。

    Practice 3  Dolly was no ordinary lamb. She was cloned from a single mammary cell of an adult ewe, overturning long- held scientific dogma that had declared such a thing biologically impossible. Her birth set off a race in laboratories around the world to duplicate the breakthrough and raised the specter of human cloning.  A decade later, scientists are starting to come to grips with just how different Dolly was. Dozens of animals have been cloned since that first little lamb and it’s becoming increasingly clear that they are all, in one way or another, defective.  It’s tempting to think of clones as perfect carbon copies of the original—down to every hair and quirk of temperament. It turns out, though, that there are various degrees of genetic replication. Not only are clones separated from the original template by time—-in Dolly’s case, six years—but they are also the product of an unnatural molecular mechanism that turns out not to be very good at making identical copies.  But scientists see a role for cloning in treating human diseases—and perhaps someday conquering some of man’s most intractable conditions. It may be another 10 years or more before the approach yields anything safe and reliable enough to be used in real patients, and there is no guarantee that it will ever be successful. But nobody thought Dolly was possible until she made history that warm July night 10 years ago.

    正确答案: 【参考译文】
    多利羊绝不是普通的羊羔,它是由成年绵羊的体细胞克隆而成。科学界长期认为克隆是生物学领域不可能创造的奇迹,多利羊的诞生颠覆了这一科学教条。它的出生使全世界各大实验室纷纷加入克隆的竞赛,希望再现这项科学上的突破,它的出生也使克隆人的可怕前景展现在我们面前。
    十年以后,科学家开始发现多利羊与普通羊的许多不同之处。克隆羊诞生后,数十种动物都复制出来,但是有越来越多的情况表明,这些克隆动物存在着这样或那样的缺陷。
    我们希望克隆出的个体是母体的翻版,小到每一根毛发,大到每一点脾性的怪癖,都毫无二致。然而,事实表明,尽管基因在不同程度上得到了复制,却仍然存在不少缺陷。首先,克隆的个体和母体在时间上有断层,多利羊和它的母体羊就相差六岁,同时,克隆个体仍然是人工分子机制的产物,这样的机制似乎还不擅长进行完全复制。
    科学家认为克隆在治疗人类疾病方面将起到一定作用,也许终有一天能够克服一些最难以寻找病因的人类疾病。要达到安全可靠的结果尚需时日,需要十年,也许更长,成功与否也未能完全确定。但是有谁想过多利羊能够出世呢?而在十年前那个温暖的六月夜晚,多利羊创造了历史。

    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

    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。

    [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

    That scientists have cloned a sheep sends academics and the public into a panic at the prospect that humans might be next. That's an understandable reaction.(46)___________,so it's not unreasonable to be concerned that it might threaten human society and dignity.Yet much of the ethical oppo-- sition seems also to grow out of an unthinking disgust. And that makes it hard for even trained scientists and ethicists to see the matter clearly.While human cloning might not offer great benefits to humarnty,no one has yet made a persuasive case that it would do any real harm,either.
    (47)_______That would surely be true if a cloned individual were treated as a lesser being, with fewer rights or lower stature.But why suppose that cloned persons wouldn't share the same rights and dignity as the rest of us?A leading ethicist has suggested that cloning would violate the "right to genetic identity".(48)________It makes perfect sense to say that adult persons have a right not to be cloned without their voluntary,informed consent. But if such consent is given,whose "right"to genetic identity would be violated?
    So who will likely take advantage of cloning?Perhaps a grieving couple whose child is dying. (49)________But a cloned child born to such dubious parents stands no greater or lesser chance of being loved,or rejected,or warped than a child normally conceived.Infertile couples are also likely to seek out cloning. That such couples have other options(in vitro fertilization or adoption)is not an argument for denying them the right to clone.Or consider an example raised by Judge Richard Posner:a couple in which the husband has some tragic genetic defect. Currently,if this couple wants a genetically related child,(50)________They can reproduce naturally and risk passing on the disease to the child.They can go to a sperm bank and take a chance on unknown genes.They can try in vitro fertilization and dispose of any afflicted embryo though that might be objectionable,too.Or they can get a male relative of the father to donate sperm,if such a relative exists.This is one case where even people unnerved by cloning might see it as not the worst option.
    Even if human cloning offers no obvious benefits to humanity,why ban it?In a democratic society we don't usually pass laws outlawing something before there is actual or probable evidence of harm.Most important,human cloning should be governed by the same laws that now protect human rights.A world not safe for cloned humans would be a world not safe for the rest of us.

    _______(49)
    A:they have four not altogether pleasant options.
    B:This might seem psychologically twisted.
    C:Theologians contend that to clone a human would violate human dignity.
    D:Parents might clone a child to have"spare parts"in case the original child needs an organ transplant.
    E:Cloning is a radical challenge to the most fundamental laws of biology.
    F: Where did he come up with such a right?

    答案:B
    解析:
    文章第一段主要描述了人们对于克隆的偏见。该空的后一句是说“担心克隆会威胁人类社会和尊严不无道理”,因此前一句应该是使得人们产生这种担心的理由,我们应当选择E项,即“克隆是对生物学最基本法则的极端挑战”。
    文章第二段作者主要驳斥了“克隆侵犯了人们基因身份的权利”这一观点。与此相关的仅有选项C,即“神学家们坚持认为克隆人侵犯了人的尊严”。
    该空与前一个空在一个段落里,前一句讲到一位重要的伦理家提出克隆会侵犯人们“拥有基因身份的权利”。与之相关的仅有选项F,即“这种权利是从哪里来的呢”。
    本段作者举例证明了人们是可以从克隆中获益的,该空的前一句是说“一对伤心夫妇的孩子正奄奄一息”,只有选项B最符合题意。
    该空后面提到了四种生育方法,包括自然生产、求助于精子库、试管婴儿及父亲一方的男性亲戚捐献精子。因此与此有关系的仅有选项A,即“他们有四种不太满意的选择”。

    Cloning(克隆):Future Pertect?

    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 clonen
    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
    Joumal 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 cioning
    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 will 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

    The Mystery of Clones

    Scientists have cloned goats,cats,cows,pigs and mice.Now it has been suggested by many commentators and scientists that it might be ethically acceptable to clone existing people in certain cases.One possibility is generating a replacement for a dying relative.All such possibilities,however,makes more and more people concerned that it would be possible that the clone is subjected to expectations and limitations based on the family's knowledge of the genetic"twin",so he or she would not be treated as an individual with independent personality.For the reason that human personality is only partly determined by genes,those assumptions might not be right.The clone of a shy person might behave quite differently if he or she is brought up in a family with encouraging atmosphere.Clones of writers,scholars,scientists or athletes are very likely to choose different careers because of chance event in early life.
    Some researchers have suggested the idea that couples,in which one part is infertile,might choose to make a copy of one or the other partner. But the notion raises the concerns that the child who is a copy of just one of a couple might not treat naturally,and it is not in the interests of the resulting kid.Moreover,the treatments of all known types of infertility are available nowadays;conventional therapies seem more ethnically acceptable to ordinary people's way of thinking,so the majority of population strongly opposed to allowing cloned human embryos(胚胎)to develop.
    However,the positive side of the cloning technology cannot be denied,for instance,cloning from cultured cells will provide essential medical opportunities.Scientists are trying to grow an embryo,cloned from a single cell of a human being with goals to design therapies for diseases which are currently untreatable.
    Of course,people's predictions about this new technology might be all wrong,because social attitudes change and unexpected developments take place.Only time will tell.But biomedical researchers who are dedicated to finding the potential of cloning have plenty to do.Maybe someday soon,a human will be cloned,and mankind will embark on a scientific and moral journey whose destination is not under his own control. Or maybe one day you will be happy to have a clone of your own.

    A person's personality is determined by_______.
    A:both their genes and the environment they live in
    B:their genes
    C:the environment they live in
    D:Not mentioned

    答案:A
    解析:
    从文章第一段的第五句“human personality is only partly determined by genes”可以看出人类的性格只是部分由基因决定。接着又说一个害羞的人的克隆人若成长于一个拥有激励氛围的家庭,那么也可能会表现得截然不同,所以所处的环境也对人的性格产生影响。由此可以判断A正确。
    第二段第二句谈到被克隆出的孩子可能不会被父母以自然的方式对待, "it is not in the interests of the resulting kid",所以选B,意为“这对孩子没有好处”,not good for 和文中的not in the interests of意思一样。
    第三段提到克隆的积极面也不可否定,如“design therapies for diseases which are currently untreatable",所以选D。
    综观全文,作者提到了人们对于克隆技术的担心,也谈到克隆技术的积极面,所以作者态度是客观的、中立的(neutral:中立的),而不是赞同的(approved)或是不赞同的(disapproved)。
    最后一段说到人们对这个新技术的预测可能都是错的,所以“Only time will tell",没有人能真正知道克隆技术的未来如何,只有随着时间的流逝,克隆技术所带来的影响才能逐一显现出来,所以A正确。

    单选题
    PPL scientists will try to solve their problem by ______.
    A

    removing the sugar molecule on the surface of pig cells.

    B

    distinguishing human tissues form those of pigs.

    C

    using the sugar-free nucleus in cloning a pig.

    D

    taking out the sugar genes from the cell of a pig.


    正确答案: C
    解析:
    细节理解题。根据题干信息定位到第三段第三句“PPL scientists recently succeeded in finding the gene responsible for the sugar and knocking it out of the nucleus of a pig cell.”,由此可知,科学家们已经成功的将存在于猪的细胞核里的与糖分子相关的基因剔除了,这些基因存在于猪的细胞核,而不是细胞表面,故A选项错误;B选项的观点无中生有;PPL的科学家想用不含糖的细胞核克隆猪,防止人体产生排斥反应,以解决他们的问题,故C项正确;D选项只是解决该问题过程当中的一个步骤,不是解决问题的全部,故不选。

  • 第23题:

    问答题
    Practice 1  After nearly a year of emotional arguments in Congress but no new federal laws the national debate over the future of human cloning has shifted to the states. Six states have already banned cloning in one form or another,and this year alone 38 anticloning measures were introduced in 22 states.  The resulting patchwork of laws,people on all sides of the issue say,complicates a nationwide picture already clouded by scientific and ethnical questions over whether and how to restrict cloning or ban it altogether.  Since l997,when scientists announced the birth of Dolly the sheep,the first cloned mammal,the specter of cloned babies, infants that ate,in essence,genetic carbon copies of adults has loomed large in the public psyche and in the minds of lawmakers.  Today, there is widespread agreement that cloning fur reproduction is unsafe and should be banned. Now,the debate has shifted away from the ethics of baby-making and toward the morality of cloning embryos for their cells and tissues,which might be used to treat diseases. The controversy pits religious c6nservatives and abortion opponents, who regard embryos as nascent human life,against patients' groups,scientists and the biotechnology industry.

    正确答案: 【参考译文】
    国会经过将近一年的激烈争论但未通过新的联邦法律后,关于克隆人的未来的全国性辩论已转移到各个州。六个州早已禁止各种形式的克隆,仅今年一年,就有22个州提出了38项反克隆措施。
    在克隆问题上持各种立场的人都说,由此拼凑起来的法律会使全国性立法复杂化,而关于是否要限制及如何限制克隆或者彻底禁止克隆的科学问题和伦理问题,已经使全国性立法变得扑朔迷离。
    自1997年科学家宣布第一只克隆的哺乳动物多利羊出生以来,人们对克隆的婴儿本质上是成年人基因的复制模样感到恐惧,而这种恐惧一直萦绕在公众的心理上和立法者的头脑里。
    今天,广泛一致的意见是,用于繁殖的克隆技术是不安全的,应当禁止。现在,辩论已经从制造婴儿的伦理问题,转向为提取可用于治疗疾病的细胞和组织而克隆胚胎是否合乎道德。这一争论使认为胚胎是新生的生命的宗教保守派和堕胎反对派与患者群体、科学家和生物技术行业成为互相对立的两大阵营。
