文章大意：本文对克隆技术的发展进行了简要叙述，并摆明各国对克隆人的禁令以及科学家们对该禁令的反对意见。当然，至于人类的克隆是否会出现我们还要拭目以待。

1．A．produces 　　　　　　　 B．produce  

C．producing   D．produced

答案：D　produced from any one cell“由任何单细胞产生的”，过去分词短语作后置定语。copy与produce之间存在被动关系，因此应用过去分词短语作定语。

2．A．tried      B．succeeded

C．attempted   D．managed

答案：D　manage to do sth．“设法做成某事”；try to do sth．“努力做某事”，但不一定成功；succeed不接to do sth．；attempt to do sth．“试图做某事”，但不一定成功。而本句表示已完成的一件事情，故选D项。

3．A．taking    B．teaching 

C．using       D．learning

答案：C　using cloning technology利用克隆技术。take带走；teach教；learn学会。这三个词均不符合句意。

4．A．too       B．either   

C．also        D．as well

答案：C　also表示“也”，一般放在句中；too用于肯定句的句末；either用于否定句的句末；as well用于肯定句的句末。

5．A．reporter   B．physicist 

C．writer      D．artist

答案：B　Chicago physicist芝加哥物理学家。从事其余三项所代表的职业的人都不搞科研。reporter记者；writer作家；artist画家，艺术家。

6．A．aroused               B．rose

C．rose up                D．was raised

答案：A　aroused a lot of media's attention引起众多媒体的关注；rose是rise的过去式形式，意为“上升，上涨”；raised是raise的过去式形式，意为“抬起；引起，导致”，此处用被动形式是错的；rise up起义，升起。arouse“引起；激发”，符合句意。

7．A．signed    B．wrote    

C．drew       D．arrived

答案：A　sign an agreement签署一项协议；write“写”文字；draw画；arrive at an agreement达成协议，但D项中缺少介词at。

8．A．spoke                 B．told  

C．reported               D．announced

答案：D　the President announced．．．“总统宣布……”。speak，tell和report后都不加冒号。

9．A．the       B．a       

C．an         D．/

答案：B　introduce a law实施一项法律。此处是第一次提到该法律，因此用不定冠词修饰，表示泛指。

10．A．allowed              B．agreed   

C．passed               D．approved

答案：C　“通过”法律应用pass，而非allow(允许)、agree(同意)或approve(赞成，同意)。

11．A．in       B．for      

C．beyond     D．about

答案：D　be negative about sth．否定某事。

12．A．forbidden            B．permitting   

C．banning              D．referring

答案：C　banning human cloning(禁止克隆人)为现在分词短语作后置定语，修饰laws。forbidden形式不对，故排除。

13．A．seriously             B．personally

C．partly               D．possibly

答案：A　由上句可知此处表示“任何禁止克隆人的打算都是‘严重’错误的”。seriously“严重地”，符合语境。personally个人地；partly部分地；possibly可能地。

14．A．despite of  B．though

C．although  D．in spite of

答案：D　in spite of和despite为介词(短语)，后接名词、代词或动名词，而though和although是连词，后接从句。

15．A．possible  B．impossible

C．likely  D．probably

答案：B 　it is impossible to do sth．做某事是不可能的；it is likely to do sth．做某事是可能的。

16．A．lead to  B．stick to

C．come to  D．add up to

答案：A　lead to a nightmare world导致一个可怕的世界的产生。stick to坚持；come to谈到；add up to总共达，都不符合句意。

17．A．as much as  B．as many as

C．as well as  D．as good as

答案：C　as well as有“还有”的意思，符合句意。as much/many as像……一样多；as good as和……一样好。

18．A．puzzle   B．worry

C．wander   D．wonder

答案：D　wonder后可接表示疑问意义的从句。puzzle使迷惑；worry担忧；wander闲逛，这三个词都不接表示疑问意义的从句。

19．A．Upon  B．Within

C．Out of  D．At

答案：B　the next five to ten years“随后的五到十年”是时间段，只能用within，表示在某个范围之内。

20．A．much  B．pretty

C．too  D．more

答案：B　pretty“相当地”，含有very之意。much一般不修饰副词；  too”太”；more是比较级。

Ⅳ．阅读理解

阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

Market research has been done to see if people would accept meat from either cloned animals or the offspring(后代)of clones．A study done by the International Food Information Council in 2007 asked US respondents (调查对象) if they would buy meat，milk，and eggs from cloned animals．

Of the respondents，10%would be“very likely”，36% would be“somewhat likely”，while 28%would be “not too likely” and a quarter “not at all likely”．The respondents were slightly more favourable(乐于接受的) when asked the same question about the offspring of cloned animals．

In the US，the hormone(激素)rBST is given to cows to increase milk production．In the EU and a number of other places such hormone treatment is banned．But even in the US，milk and meat is often labelled (贴标签)as rBST hormone free．

The US Food and Drug Administration (FDA)is not requiring labelling for meat from cloned animals or offspring of clones because its position is that there is no scientific difference between that and non­cloned meat．It has said it will permit voluntary labelling．

And despite the scientific evidence it gave，there are still plenty of critics against its position on cloned meat．After the 2008 guidance was published，Senator Barbara Mikulski said：“The FDA has acted recklessly and I am very disappointed in their rush to allow cloned foods．Just because something created in a lab doesn't mean we should have to eat it．If we discover a problem with cloned food after it is in our food supply and it's not labelled，the FDA won't be able to recall it．”

文章大意：本文讲述了在美国人们对待克隆食品的态度以及存在的种种争议。

1．What's the aim of the International Food Information Council's study？

A．To prove cloned foods are safe．

B．To persuade people to eat cloned foods．

C．To find the possible bad effects of cloned foods．

D．To know people's attitudes towards cloned foods．

答案：D　细节理解题。由第一、二段可知，International Food Information Council进行这一调查和研究的目的是了解人们对克隆食品的态度。

2．The underlined word“recklessly”in Paragraph 5 is the closest in meaning to________．

A．carelessly  B．formally

C．effectively  D．uselessly

答案：A　词义猜测题。根据下文“我很失望他们匆忙地许可了克隆食物”，可以判断前面recklessly一词应该表示“草率地；鲁莽地”之意。

3．According to Senator Barbara Mikulski，________．

A．cloning animals is illegal

B．cloned foods should be labelled

C．cloned foods should be forbidden

D．cloned foods have health problems

答案：B　推理判断题。根据Barbara Mikulski所说的“如果人们食用了克隆食品出了健康问题的话，如果没有标签这些食物将无法被召回”可推断他认为应该对克隆食品进行标签，因此判断B项正确。

4．What's the best title for the passage？

A．Why do people in the US not like to accept cloned food？

B．Differences between cloned and non­cloned meat

C．What are the attitudes towards cloned food in the US？

D．Various responses to a study on cloned food

答案：C　主旨大意题。该文主要讲述了美国人对待克隆食品的态度以及存在的种种争议，因此C项作为标题最合适。
