一、can的用法。

not c.考查can / could表示请求许可的用法?
在这一用法中,can和could都表示现在,用could比用can语气更加委婉客气,常用could i / you……?句式,表示“我/你能……吗?”若表示同意要用can,不用could?

to回答must开头的一般疑问句,如果是否定的回答,要用needn’t或don’t h**e to,表示“不必”,“没有必要”的意思,不用mustn’t,因为mustn’t表示禁止或不许,意思是“一定不要”的意思。肯定回答,则用must。例如:
8、-must i finish the work before five o’clock?
-no,you___
tob.考查must表示推测的用法。

,不用no,you may not.?例如:

and ask the answer.(2003天津)
