分析 短文主要介绍了克隆羊多利以及克隆对社会造成的影响.
解答 61.is known,考查时态和语态,主语与know构成被动的关系,因此使用被动语态,描述的是一般事实,因此使用一般现在时,be known as"作为…被人们所认知".
62.called,考查非谓语,lamb与call构成被动的关系,因此使用过去分词充当非谓语.
63.covers,考查名词,cover"封面"是可数名词,因此使用其复数形式.
64.possibility,考查名词,表示"再生产的可能性"使用possible的名词形式.
65.that/which,考查定语从句,句子先行词是breakthrough,引导定语从句使用that/which.
66.what,考查主语从句,从句缺少think后的宾语,因此使用表示"什么"的what引导.
67.undertaking,考查动名词,undertake的动词短语位于主语的位置,因此使用其动名词形式.
68.to experience,考查动词不定式,be bound to do sth."一定会做某事".
69.social,考查形容词,and连接两个并列的成分,前面psychological是形容词,因此使用society的形容词形式.
70.in,考查介词,in favor of sth."赞成".
点评 对于语法填空这类题,一是懂得分析句子结构,二是知道充当各个句子成分的词类或词性,从语法上确定答案,当然,对于某些固定搭配也要牢记,在平时的学习中要多积累这些词汇或短语,对于句子使用的时态语态也要通过语境进行确定.
