含有must的反义疑问句(must的反义疑问句用法及回答)

导语:含must的反义疑问句需要注意的几个地方!

陈述句的谓语中包括情态动词must时,疑问尾句用何种助动词,与陈述句中的整个谓语所表达的含义有关。因此,要对具体的句子做具体的分析。

1)对现在情况的推测,问句部分用助动词(do,be)的一般现在时的适当形式。若是there be结构,问句用isn't/aren't there。如:

1)He must be waiting for the train,isn't he?

2)She must be there,isn't she?

3)There must be some students in the room,aren't there?

2)对已发生的过去情况的推测,若陈述句谓语部分有“must have done”,而且有表示过去的时间状语,问句部分用didn't;若没有表示过去的时间状语,问句部分最好用haven't或hasn't,也可以用didn't如:

1)It must have rained last night,didn't it?

2)They must have arrived by now,haven't they?(根据by now来判断)

3)They must have been to the Great Wall,haven't they?

3)must表示'应该"的意思,疑问尾句用needn't构成,如:

1)You must go home, needn't you?

2)We must hand in our homework on time,needn't we?

4)must表示“不得”时,疑问尾句用must构成,如:

1)We mustn't be late,must we?

2)You mustn"t touch the wire,must you?

5)若句中有表示过去完成时的时间状语,问句部分应用hadn't.如:

They must have learnt 5000 English words by the end of last term,hadn't they?
