特殊的情态动词must
We must finish our homework on time, mustn’t we
1）作为情态动词表“必须”，这时反意疑问句直接用mustn't/needn't
The baby must be sleeping now, isn’t he
2)表示推测时，由must后面的动词决定。
must have done... 表示对过去事实的肯定推测
“must have done”，表示对对过去事实的肯定推测
eg.
They must have gone there last night, didn't they
They must have arrived by now, haven't they
They must have been to the Great Wall, haven't they
They must have learnt 5000 English words by the end of last term, hadn't they
1. 有表示过去的时间状语，问句用过去时didn't；
2. 没有表示过去的时间状语，问句用现在完成时haven't或hasn't。
3. 陈述句中有表示过去完成时的时间状语，问句用hadn't.
特殊的情态动词
He used to smoke a lot, didn’t/usedn’t he
谓语为used to（曾经；过去经常），简短问句为didn’ t/
usedn’ t+主语
He had better find his wallet, hadn’t he
谓语为had better最好做时，简短问句用hadn’t+主语。
You ought to take care of them, oughtn’t/shouldn’t you

should(n't)+主语。
特殊的情态动词
He has a lot of things to do today, doesn’t he
She has been to the city several times, hasn’t she
谓语为have/has“有”时，问句：do的适当形式+主语 ；
若have/has作助动词时，则用have/has的适当形式。
They needn’t hand in their homework today, need they
We need more information to make a decision, don’t we
need/dare作情态动词时，问句用need(n’t)/dare(n’t)；
作实义动词“需要/敢”时，借助助动词do的适当形式。
