含有情態(tài)動詞的被動語態(tài),如何變成被動語態(tài)的一般疑問句?
只要把情態(tài)動詞調(diào)前就可以了.

Your homework should be finished(by you) at once.
Should my homework be finished at once?-Yes,it should./ No,it shouldn‘t.
This work must be done at once.
Must this work be done at once?-Yes,it must./ No,it needn‘t.
回答應保留原情態(tài)動詞,但must表"必須"時,其否定回答應用needn‘t,need表"必要"時,其肯定回答應用must.這和主動語態(tài)類似.不是把be動詞提前嗎？不是!是將情態(tài)動詞提前。改成(一般)問句，是把第一個動詞提前。
