With human cloning becoming a hot issue, we are brought face to face with the most basic ethical questions of life. Opinions differ widely as to 1 human cloning should be 2 or not.

True, human cloning clearly has much to offer. By using the cells from the patient’s own body to grow organs to 3 the diseased parts, the problem of 4 can be avoided. This might prove useful, for example, in fighting leukemia (白血病) through bone marrow (髓)transplants. But what about making an 5 copy of a human being?

Ian Wilmut, who created the sheep Dolly, finds the idea 6 . Professor Hank Greely at Stanford also finds the suggestion deeply 7 . For one thing, the technology is 8 from perfect. There 9 be lots of miscarriages(流产)and deformed clones. What shall we

do with them? Shall we keep the healthy clones and just kill off the ones with a deformed body and 10 brains? That would offend the 11 beliefs of many people. For 12 , even if the technology is perfected, who can 13 no one will misuse it for evil purposes?

Therefore, I am strongly opposed 14 human cloning for reproductive purposes. The government 15 enact laws to deal with it 16 it is too late. None-reproductive cloning, on the other hand, should be encouraged. It may mean hope to many 17 are waiting desperately for organs for transplant to save their lives. If 18 wisely the technology may eventually free humans 19 many kinds of suffering that today 20 unavoidable.

31省市学位英语网https://www.360docs.net/doc/e813980075.html, 专家精讲答案:

1.C。此题考察的是whether… or not的搭配。unless“除非”,意思相当于if not;if不与

or not搭配使用;how在此句中不可使用。

2.B。此题考察的是四个词的意义。control“控制”,prohibit“禁止”,isolate“隔离,孤立”,

regulate“调节,管制”。根据上下文含义此句的意思是“在是否禁止克隆人的问题上有许多不同看法”。

3.A。词义及词形辨析题。replace和displace都含有“代替”之意;replay“重放”,display

“展示,陈列”。根据上下文含义,可知此句的意思是“用成体细胞培养出的器官取代患病的器官”,由此排除replay和display;而displace则强调“强迫替代”,与句意不符。

因此replace是最佳选择。

4.D。词义辨析题。根据句意不难看出此句的意思是:器官的排异反应可以避免。在四个

选项中,只有rejection指医学上的“排异或排斥反应”。refusal“拒绝”;exclusion“排除”;resistance“抵抗”。

5.A。词义辨析题。在四个选项中,identical与equal意思有些相似,但是identical更强调

“完全等同,完全一样”,例如:identical twins同卵双胞胎。而equal则侧重于”平等,等值”,例如:People are equal before the law.(法律面前人人平等。)exact和accurate的意思是“准确的,正确的”。

6.D。词义辨析与语义理解题。Objective“客观的”;negative与positive是一对反义词,

分别表示“消极的,否定的”和“积极的,肯定的”;offensive“令人不快的,冒犯的”。

从上下文来看,虽然Ian Wilmut创造了Dolly,但他对于克隆人的想法并不赞成,第三段解释了其原因,因此offensive最为合适。

7.B。分词用法题。此句的意思与上句意思一样,Professor Hank Greely与Ian Wilmat都认

为克隆人的想法令人懊恼,使人不快。disturbed“扰乱的,干扰的”,人做主语;disturbing “令人烦恼的”,与offensive同义。其他选项不符合句意。

8.C。习惯用法题。此题考察的是固定用法far from…,意为“远非…,远远不…,完全不…”,

例如:The battle is far from over.(战斗远远没有结束。)和What he said is far from true.

(他所说的远非事实。)away“离开”,强调“距离”;distant强调“两物相距的间隔”,例如:The ability to do this will be necessary in future flights to distant planets.(将来飞往遥远的行星时,需要这样的能力。)further表示“更远的,深一层的”。

9.B。语气辨析题。此句的意思表示语气较弱的可能性,意为“克隆技术还远远不够完善,

可能会有许多流产和畸形的克隆产品”,只有may最符合句意。Must的语气强,should 和can意思不符。

10.B。形近词辨析题。这是四个形近词的比较,也是最容易混淆出错的地方。defensive的

意思是“自卫的,防御的”;defective的意思是“有缺陷的,(智商或行为有)欠缺的”;

definite的意思是“明确的,一定的”;deflective“歪斜的,偏斜的”。根据所修饰的名词brains可以很容易地推断出答案是defective,意为“有缺陷的大脑”。

11.C。词义辨析题。Racial与ethnic同义,意为“人种的,种族的”,经常与discrimination,

prejudice,equality等表示歧视、偏见、平等的词汇连用;religious指“宗教的”,经常与belief,conviction等表示信仰、信念的词汇连用;moral意为“道德上的”,经常与standards,principles,values等表示标准、原则、价值观的词汇连用。根据上下文含义,

此句的意思为上述的情况与世界各地很多人的宗教信仰相违背。

12.D。固定搭配。for one thing…,for another是固定用法,表示“一方面,另一方面”,多

用于陈述理由及原因。其他选项均不符合题意。

13.D。近义词用法辨析题。promise“允诺,答应”,常用promise to do或promise sb that的

用法;assure“向(某人)保证;使确信”,常用assure sb of sth或assure sb that的用法;

convince“使确信,使信服”,用法与assure相同。guarantee“确保,保证”,常用guarantee to do sth,guarantee sb sth以及guarantee (that)的用法,例如:we cannot guarantee that you are going to get the cheapest fare possible.(我们不能保证你得到可能的最低票价。)

14.A。be opposed to“反对”,是固定搭配,其他选项不与oppose搭配。

15.B。语气辨析题。从上下文语气来看,“我”强烈反对用于繁殖用途的克隆人,因此政府

应该制定法律来应对。should最为合适,因为它的语气介于can 和must之间,比can 表示可能的语气要强一些,又比must表示必须的语气弱一些;would侧重于“主观意愿”。

16.C。语篇衔接题。根据此句的句意,可以明显地看出用after,until及when均不合适,

政府制定法律不能等到为时已晚或已经为时已晚,因此只能用before,表示一切还为时不晚时制定法律加以应对。

17.D。语篇衔接题。此句是一个定语从句,修饰先行词many。这里many指many people,

因此答案是who为最佳。

18.B。分词用法题。此题考察的是分词这个语法点。应首先将use和uses排除。然后再看

从句的主语与主句主语是何关系,是主动进行,就用现在分词;是被动完成,就用过去分词。显然,use和technology之间是被动关系,应选择used。

19.C。习惯用法题。free sb from…是习惯用法,意为“从…解除…,释放…,使…摆脱…”;

此处的意思是“使人类摆脱各种痛苦”。

20.A。主谓一致题。此题考察的是主谓一致的语法点。that today seem unavoidable是定语

从句,修饰many kinds of suffering,关键词是kinds,因此不能用seems,正确答案为seem。
