Answer 1

答案：61．to copy/copying；考查动词搭配．learn doing/to do sth学会做某事，常用搭配短语；句意表达的是鹦鹉学会了模仿人的声音． 
62．to；考查动词短语．add…to…把…加到…上，固定搭配；句意表达的是现在我们可以把大象加入到盲目模仿者的名单上了．  
63．who；考查连词．句中studies the sounds of elephants修饰名词zoologist，是一个非限制性定语从句；从句缺少主语，且先行词zoologist指人，要用who来引导．  
64．made；考查分词．句中make作noises的后置定语，要用非谓语动词；make与noises构成动宾关系，要用表示被动的过去分词来构成．  
65．an；考查冠词．句意表达的是泛指一头八岁大的非洲象，要用不定冠词来限定；eight是以元音开头，要用an来限定．
66．couldn't；考查句意理解．句意表达的是Poole博士不能区分Mlaika的声音和卡车的声音；句意表达的是过去的事实，要用couldn't来构成．  
67．distant；考查形容词．句中distance修饰名词truck，要用形容词形式． 
68．it；考查代词．句意指代的是前面提到的大象Mlaika，要用it来指代．  
69．When；考查连词．句中有逗号分隔，要用连词；句意表达的是当他们脱离了自然环境时，他们会模仿不同寻常的声音，要用when来连词时间状语从句．  
70．has spent；考查时态．句意表达的是到目前为止Poole博士已经和两头亚洲雌象共处了十八年；so far到目前为止，是现在完成时态的时间状语；主语Dr．Poole是单数，助动词要用has．
