| A． | mustn't； Her | B． | can't； Her | C． | can't； Hers | D． | may； Hers |
分析 --我想知道这个智能机是否是玛丽的．
--不可能属于她，她的和这个完全不同．
解答 答案：C．mustn't不可以，禁止；can't不可能；may可能；her形容词性物主代词；hers名词性物主代词．根据totally different from this one，可知这手机与她的完全不同，故不可能是她的，前面用can't．形容词性的物主代词后一定有一个被修饰的名词，名词性的物主代词后没有被其修饰的词，本题后没有被修饰的词，用名词性的物主代词，"她的"：hers．故选C．
点评 本题考查了情态动词的用法．熟知句意以及所给选项的意思是解答本题的关键．
