  Cloning may have _6_ uses besides its ability to help farmers _7_ breed quality burgers andbacon. Other potential uses _8_ the preservation of species, biomedical research, drug andorgan production and even commercial ventures.

  It seems that finding out exactly how many cloned animals have been produced is almost asdifficult as producing them in the first place. There’s no official _9_ of clones, and laboratoriesaren't required to report every single tadpole or mouse they create. But armed with a bit ofknowledge concerning animal cloning and its _10_, it’s likely to narrow down the contestants toa possible field.

  六级选词填空模拟练习题答案

  1.[D]空格前后分别为句子的主语和谓语,因此空格应为副词。前一句中的half right表明本句将要说出“真正的”答案,故选actually,说明上文提到的那些名字“事实上”是几种克隆动物的名字。

  2.[H]空格应为形容词、名词或分词,作定语修饰status。上文提到的几种克隆动物的名字不太为人所熟悉,而这里所讲的多利羊(Dolly)很多人知晓(familiar),故此处选用celebrity,表明多利羊“很出名”。

  3.[L]空格在定冠词和名词之间,为修饰名词的定语。From…to…结构表明空格最有可能是形容词,这样the...guar形式上才能与the common crow—致。该句前面提及很多不同物种被克隆了,其后举例加以说明, 由此推断此处应该是从“普遍”到“特殊”的列举,endangered符合语义。

  4.[B]空格位于that引导的从句中,从句的主语是food products,谓语是are safe,可见空格应该是修饰foodproducts的后置定语。from the clones of...表明填人空格的词应表示某种动向且能与from搭配,最可能是过去分词。derived符合句意,表明“源自克隆牛、克隆猪和克隆羊的食物可以安全食用”。

  5.[F]通过分析句子成分可知,空格是主句的谓语,与an already growing interest构成动宾搭配,其主语是declaration。in early 2008提示谓语动词为一般过去时。动词库中intensified“增强”能与interest;构成动宾搭配,填入空格句意通顺。

  6.[E]空格在名词uses之前,作其定语。下一句提到克隆技术可能用于保存物种、生物医学研究等,可知这一技术除帮农民生产出汉堡包和熏猪肉外,还有其他用途。additional符合句意。

  7.[O]空格在动词词组help... breed之间,应为副词。本段讲克隆技术的好处,故填入的副词应包含积极意义,consistently符合语境,表示“源源不断地”生产出髙质量的汉堡包和熏猪肉。

  8.[I]空格处应为动词,作句子谓语。主语为other potential uses,宾语为克隆技术应用的各领域,词库中动词include “包括”符合此处句意。

  9.[M]空格位于no和介词of之间,应为名词,且被official修饰。本句解释难以确切知道有多少克隆动物的原因,此处指出其中一个原因“没有关于克隆的官方……”,registry符合句意。

  10.[C]空格在形容词性物主代词its后,应为名词。本句说的是找到更多克隆动物的方法,那就要具备这方面的相关知识,此处应选用applications,填人文中意为“只要掌握一点关于克隆及其应用的知识,就能缩小找寻被克隆的动物的范围”。
