分析 短文主要讲了克隆多利之后,一群英国学生来周口店洞穴研究以前的动物.
解答 61.copy,考查名词,根据中文意思和an可知使用名词单数copy.
62.to undertake,考查动词不定式,此处应使用动词不定式充当后置定语.
63.while/but,考查连词,前后句子表示转折的关系,因此使用 while/but.
64.impact/effect/influence,考查名词,根据中文意思和冠词a可知使用单数名词impact/effect/influence.
65.that,考查强调句,其构成为it is…that…
66.have been excavating,考查时态,句子有时间状语for many years,可知使用现在完成进行时.
67.reasonable,考查形容词,位于be动词后应使用形容词reasonable"合理的".
68.regardless,考查固定搭配,regardless of"不管,不顾".
69.sharpened,考查非谓语,sharp是形容词,根据语境表示"被磨尖的石具"使用动词sharpen,其与逻辑主语stone tools构成被动的关系,因此使用过去分词形式.
70.it,考查代词,此处指代前面提到的skin,使用代词it.
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.
