s party﹖
—I’m not sure. I ____ go to the concert instead. (NMET2000)
A. must B. would C. should D. might
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. couldC
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。
