must的反义疑问句问题.请重点说一下must have done把.我不太明白,为什么有些用don't,有些用haven't,有些是be动词呢?she must have finished reading the novel last night,____?
she must have finished reading the novel last night,【didn't she
句中有时间的标志性短语 last night,时态就只能用一般过去时,不可以用完成时.【反义疑问句肯定要根据时态,所以是didn't she 】
陈述部分有must 的疑问句,疑问部分根据实际情况而定.
A.must表示“应该”,其疑问部分用mustn't(不应该),如:You must work hard next term,mustn't you 下学期你应该努力学习,对吗?
B.must表示“必须”,其疑问部分用needn't(不必),如:They must finish the work today,needn’t they?他们今天必须要完成这项工作,是吗?
C.陈述部分含情态动词mustn't,表示禁止时,疑问部分就可以用must或may,如:You mustn’t stop your car here,must you?(may we?)你不能把车停在这地方,知道吗?
D.must表示推测 ,其疑问部分必须与must 后面的主要动词相呼应.如:
①对现在动作或存在的情况的推测 :You must know the answer to the exercise,don't you?你一定知道这项练习的答案,是不是?  That must be your bed,isn't it?那一定是你的床,是吗?
②对过去发生的动作或存在的情况的推测:
a 表示肯定推测
(一)句中陈述部分没有表示过去的时间状语,这时疑问部分中的动词就用现在完成时.(haven’t / hasn’t + 主语)   You must have told her about it,haven’t you?你一定把这事告诉她了,是吗?
