Question

Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene（基因） is complete．Couple of years ago, this seems an impossible task for scientist to accomplish．All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away．Human cloning has always been a topic of argument, in terms of morality or religion．

         Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning．If the clone was free of genetic limitations．then the other clone would be as well．The latter could foe inserted in the woman and allowed to ripen to term．Moreover, cloning would enable women, who can't get pregnant, to have children of their own．

         Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs．This, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single （or more） organ （s）．It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists．

         Arguments against cloning are also on a perfectly practical side．Primarily, I believe that cloning would step in the normal "cycle" of life．There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development—the fundamental reason how living things naturally adapt to the ever-changing environment．Life processes failing to do so might result in untimely disappearance．Furthermore, cloning would make the uniqueness that each one of us possesses disappear．Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would be regarded as "objects" rather than people in the society．

         Scientists haven't 100 per cent．guaranteed that the first cloned humans will be normal．Thus this could result in introduction of additional limitations in the human "gene-pool"．

         Regarding such arguable topics in "black or white" approach seems very innocent to me personally．We should rather try to look at all "shades" of it．I believe that cloning is only legal if its purpose is for cloning organs; not humans．Then we could regard this as for "saving life" instead of "creating life"．I believe cloning humans is morally and socially unacceptable．

1.Which of the following is true according to the passage?

A．Genetic limitation will be beneficial for some women

B．A large number of genes will prevent us from developing

C．Prohibition of cloning might limit the freedom of scientists

D．First cloned humans might be normal according to scientists

2.What's the author's opinion on cloning?

A．Cloning should be entirely banned．

B．Cloning should be used in creating life．

C．Cloning will take away the right to reproduce．

D．Cloning is acceptable if it is used for cloning organs．

3.Where can you read this article?

A．In a story book

B．In a magazine

C．In a science fiction

D．In a brochure

4.Which of the following shows the structure of the passage?

 

 

Answer 1

【答案】

 

1.Ｃ

2.Ｄ

3.Ｂ

4.Ａ

【解析】

試題分析：最近在科學研究方面有了大的發(fā)現(xiàn)---人類基因的完整圖譜。這一重大發(fā)現(xiàn)使人們相信克隆人的那一天不在遙遠�？寺∪艘恢笔艿綘幾h，從道德和宗教方面來說。但是克隆人有好處：一是使那些不孕不育的女性有自己的孩子；二是可以用來克隆器官。但是克隆人使人不在具有唯一性，而且也不能保證正常。所以，克隆器官可以被接受�？寺∪藷o論從道德上還是社會上都不能被接受。

1.推理判斷題。根據(jù)倒數(shù)第二段的意思：科學家到現(xiàn)在還不能確定第一批克隆人是否正常，這樣就會限制科學家在人類基因方面的研究增加限制。故選C 。

2.推理判斷題。根據(jù)最后一段的I believe that cloning is only legal if its purpose is for cloning organs; not humans．（我認為克隆是合法的，如果目的是克隆器官而不是人。）。由此判斷選擇D。

3.推理判斷題。通讀全文判斷，文章是對克隆人的優(yōu)點和缺點作了分析，不是選自故事書，也不是科幻小說，更不是小冊子，推斷B（雜志）最佳。

4.結(jié)構(gòu)分析題。全文各段的內(nèi)容分析：第一段闡明觀點，第2、3、4、5分別再具體說明觀點，最后一段總結(jié)。由此判斷Ａ最佳。

考點：科普類短文閱讀。
