     由题意和下句中的 “I'm not sure” 可知这段对话中存在一种可能性推测,might可以用来表示一种比较委婉的可能性判断,故本题选D。又如:

     I should have been there, but I _____ not find the time. (上海2000春)

     A.would B.could C.might D.should

     分析题意可知第二个分句表示过去的某种能力;C 项只表示语气上的可能性,与题意不符。故本题选B。

     9) Johnny, you ____ play with the knife, you ____ hurt yourself. (NMET'96)

     A.won't; can't B.mustn't; may

     C.shouldn't; must D.can't; shouldn't

     mustn't 表示“不可以;禁止”,分析题意可知第二个空表示某种可能性,故本题选B。

     10) —Will you stay for lunch

     —Sorry, ______. My brother is coming to see me. (NMET'99)

     A.I mustn't B.I can't C.I needn't D.I won't

     分析题意可知因为“我弟弟要来看我”,所以“不能留下”,因此对别人的邀请或要求应给予礼貌的拒绝。A 项表示“禁止”;C项表示“不必要”;而D项表示“不会”,均不符合题意。故本题选B。又如:

     —Could I borrow your dictionary?

     —Yes, of course you _____.(MET'92)

     A.might B.will C.can D.should (C)

     11)—When can I come for the photos? I need them tomorrow afternoon.

     —They _____ be ready by 1200. (NMET'98)

     A.can B.should C.might D.need

     该题考查情态动词should的基本含义,分析句意可知本题应选B。又如:

     The old man is always hunting the lions, so terrible things ____ happen to him.(上海'96)

     A.might B.would C.should D. could ?

     12)The fire spread through the hotel very quickly but everyone ____ get out.(NMET'97)

     A.had to B.would C.could D.was able to

     该题考查了could和be able to的区别,二者都可表示过去时间的能力,但如果表示过去成功地做了某事只能使用was / were able to do,故本题选D。

     13)—Shall I tell John about it?

     —No, you ___.I've told him already. (NMET'94)

     A.needn't B.wouldn't C.mustn't D.shouldn't

     情态动词shall在试题中表示征询对方意见或请求指示。答句暗示 “没有必要了”,故本题选A。
