语法:情态动词(Modal Verbs)

1) must


  We must obey the rules.我们必须遵守规则。

  You mustn’t talk like that.你可不能那样说话。


  She said that we must wait a little while.她说我们必须要等一会儿。


  must have则表示对过去情况的推测。例如:

  This must be Tom’s room. 这准是Tom的房间。

  Jack must have gone there, hasn’t he? / didn’t he?杰克准是去过那儿了,对不对?

C.比较:have to也表示“必须”,但have to更强调客观需要,must着重说明主观看法。如:

  We had to be there at 10 o’clock.我们得在10点到那儿。(客观需要)

  We must be back before 10 o’clock.我们必须10点前回来。(主观认为)


  We must / have to leave now.我们得走了。

  must和have to的否定式即mustn’t和don’t have to意思完全不同。Mustn’t表示“不作某事”,有禁止的含义;don’t have to表示“不必要(作某事)”,含有“客观上无此必要”的意思。例如:

  You mustn’t move someone if the person is badly hurt.如果这人受了重伤,你一定不要动他.

  The person isn’t hurt at all. You don’t have to give him first aid.这个人根本就没有受伤,你不必给他进行急救。
