7.-Why she buy that expensive coat when these cheaper ones are just as good.-It doesn't make sense,does it?( )
A. | must | B. | shall | C. | can | D. | may |
分析 --既然这些便宜的衣服一样很好,为什么她偏要买那件贵的呢?
--那是不合理的,是不是?
解答 答案:A.根据buy that expensive coat (买那件贵的)when these cheaper ones are just as good(既然这些便宜的衣服一样很好)可知她偏要做这种不合理的事,所以用must 表示"偏要",因此答案是A.其他情态动词没有这种用法.
点评 考查情态动词.must的用法:
(1)(表义务、必要性、命令)必须,得,要
"Must I wash the dishes at once?""No,you needn't.""我得立刻洗这些盘子吗?""不,不必."
【注】mustn't表"禁止、不准".
You mustn't play with the knife;you may hurt yourself.你不可玩刀子,你会把自己割伤的.
(2)(表必然性)必定
Everyone must die.每个人都必定会死.
(3)(表固执、不满等)偏偏;硬要;偏要
If you must know,I'm going to help him look for an apartment.如果你偏要知道,那我告诉你,我要去帮助他找一套公寓.
