Must提问的回答A:Must I do.? B: Yes， you must. No， you neednt/you dont have to四.在反意疑问句中，当附属部分有推测意义的情态动词时，疑问部分应根据情态动词后面的情况来判断。如He must be a worker, isnt he用must,may,might,may not和cant+do或be e.g.She must be at home now. The boy may play now. 推测用must,may,might,may not和cant+have done e.g.She might have been ill yesterday. He must have hold the party. 情态动词must, can, could, may, might表推测的用法 情态动词中的must, can, could, may, might都表推测。其中must的可能性最大，can / could次之，may / might最小。具体用法如下：2.can / could的用法 （1）can表示推测“可能性”时，往往用于否定句或疑问句。（2）may, might表推测时，可以用于否定句，意思是“可能不、也许不”，但不用于疑问句。一 情态动词表示推测的用法及练习(must/cant/may might could) _表示一定;_ 表示可能;_ 表示不可能 二以 Must I 开头的句子；肯定回答：Yes,you_ 否定回答：No,you _ _ _/ No,you_. 1.Whose notebook is this?
