【题目】The employee might have been dismissed by the employer last month,______ ?
A. hasn't he B. didn't he C. wasn't he D. mightn't he
在线课程【答案】C
【解析】考查反意疑问句。句意：该雇员上个月也许已经被雇主除名。一般情况下，反意疑问部分取决于主句谓语动词，如He is kind,isn’t he?但在must/might/could have done等表示推测的句子中，如果有明确的时间状语，反意疑问部分取决于该时间状语。last month用于过去时，故选C。
