Question

As I understand, if scientists produced a human clone, there would be a great risk of it having a disease. Nobody seems to understand the ageing process of a clone. It would be terrible if a baby was the age of its parent at     31   . Its cells would grow old fast and it would die young.    32    until the technique is perfectly safe, it should be     33   .

I'd love to have a clone of     34   . I often wish I had a twin sister, someone who    35   me in everything. So why not a clone? Well, the idea    36   be fun but I'm not sure if it would be     37   . I think we would be playing with fire if we let scientists go ahead with     38   cloning. There are so many     39   

involved that all research in this area should be strictly controlled.

There are so many arguments     40    cloning that it is difficult to get anyone to consider the possible benefits. I am     41    that it is a technique which could be beneficial. The most obvious use would be for childless     42   . They would be able to have babies with their own genetic material. I don't see what's wrong with that.

Imagine a child     43    up knowing that his or her mother is really a sister or a brother. The emotional     44    on the child would be     45   . Or a child who was cloned from a dead brother or sister. What kind of emotional pressure would they feel, knowing they were made as a replacement for another? The whole idea

    46    me!

It's all very good to ban human cloning but scientists should be allowed to   47   

research. If they don't, we may     48    important benefits for our society, such as producing body organs. A clone is an     49    copy of a person with the same gene. Therefore, it is the     50    donor for an organ(器官) transplant.

【解析】文章讲述的是关于人类克隆的话题，讲述了人类克隆可能会出现的问题和可能对人类社会带来的益处。

1.句意理解，如果一个婴儿刚出生就跟他的父母同龄，这将会是很恐怖的事情。

2.句意理解，这个婴儿的细胞很快地衰老，并且很早就会死掉，因此，直到这个技术完全安全了，它将会被禁止使用。

3.同上

4.上下文，根据后面的I often wish I had a twin sister可知，作者想要克隆她自己。因为她一直想有个双胞胎姐妹

5.上下文，根据上文可知，作者想要有一个双胞胎姐妹，跟自己一样，即resemble，意为，相像

6.情态动词，这个想法可能很有趣，但是我不确定这是否安全。May 可能 ，must 必须 can 可能（理论上的可能），shall将要

7.同上，在第32空也有体现

8.上下文，作者此处讲的是克隆自己，所以是人类的克隆

9.上下文，根据后面的all research in this area should be strictly controlled可知，克隆是因为存在很多风险，所以要被严格地控制

10.上下文，根据后文的 it is difficult to get anyone to consider the possible benefits可知，这是反对克隆的观点，所以选择argue against即反对

11.上下文，后面的 it is a technique which could be beneficial是作者个人的观点，所以要选择B，意为我深信，这个技术是可以对人类有益的。

12.上下文，根据childless可知，此处指的是没有孩子的夫妻可以克隆一个自己的孩子。

13.句意理解，此处意为，当一个孩子长大后发现他的父母是他的兄弟姐妹的话，他精神上的压力将会是无法承受的

14.上下文，根据后面的What kind of emotional pressure would they feel可知

15.同43

16.句意理解，这种想法让我自己都吓到了。

17.上下文，根据后面的If they don't, we may     48    important benefits for our society可知，作者支持科学家继续研究克隆

18.句意理解，如果不继续研究的话，我们可能会错过很多对社会有益的东西，

19.克隆是对一个人的完全相同的基因复制，因此这是器官移植的理想捐赠方式 identical意为完全一样的

20.ideal意为理想的
