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.
选项 What is the author's attitude towards cloning technology?
A: Disapproved.       
B:Approved.
C:Neutral.       
D:No opinion.
答案C
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。
