—Isn’t Ann’s husband over there?
—No, it _____ be him — I’m sure he doesn’t wear glasses.
A．can’tB．must notC．won’tD．may not
A

試題分析：本題考察的是情態(tài)動(dòng)詞表示推測(cè)，can’t表示有把握的否定推測(cè)“不可能”；must not禁止，千萬(wàn)不能；won’t不會(huì)；may not也許不…；句義：—那邊的不是Ann的丈夫嗎？—不可能是他。我確信他不戴眼鏡。根據(jù)I’m sure he doesn’t wear glasses.可知后者確信不可能是Ann的丈夫，故使用can’t表示有把握的否定推測(cè)。故A正確。
