一、熟悉情态动词委婉用法:
could, would, might等情态动词均有委婉用法,它们不是过去式而是表示语气委婉、客气、礼貌,常用与疑问句,并多用于习惯表达, 如would you please, would you mind, would you like to等,might还可以用于肯定句表示推测,表示可能性小, might和could表示征求对方意见时,回答必须还成may, can.
1:--Could I borrow your dictionary?—Yes, of course you____. A. might B. will C. can D. should
析:选C。该句用can的委婉表达式could 来征求对方意见,could 和might通用,但回答时必须还成can或may,因此该题不选A.
2. Would you like to do it for me ? Yes. I would.
