最可能考的几个情态动词
考频第一名:must/may/ could/ought to …+ have done
“情态动词+完成形式”是高考中很常见的一类题目,需要注意:不同情态动词与完成形式搭配时表示的不同含义。
【例1】(2005年江苏卷)---- The woman biologist stayed in Africa studying wild
animals for 13 years before she returned.
---- Oh, dear! She _______ a lot of difficulties!
go through B. might go through
C. ought to have gone through D. must have gone through
答案:D
试题解析:检查考生对情态动词表示判断的掌握和运用能力。首先,对过去发生事情的判断用情态动词+完成形式;其次,ought to have done
表示“本应该……”,即事情没有做,所以不符合语境。must have done 表示“肯定……”。
【例2】(2008年山东卷)Thank you for all your hard work last week. I don’t think we
___ it without you.
A. can manage B. could have managed C. could manage D. can have
managed
答案:B
试题解析:前句中有last week 这个时间状语,可判断动作发生在过去,结合句意,用could have done 表示原本能够做某事。
考频第二名:can
can 常用于表示“能够”,说明具有做某事的能力,但在近几年的高考中,can 常考的类型是用于表示可能性的“有时可能会”。
【例1】(2008年福建).It is usually warm in my hometown in March, but it ____be
rather cold sometimes.
A. must B. can C. should D. would
答案:B
试题解析:这道题目的题干部分有对一般情况的说明,用“usually”和“at
times”表示,说明通常情况之外,有时候会出现某些可能,所以都用到“can”来表示有时可能会。
考频第三名:should
【例1】(2008年上海卷)According to the air traffic rules, you _____ switch off
your mobile phone before boarding.
A. may B. can C. would D. should
答案:D
试题解析:此句中的should 表示这样做是最好的,
考频第四名: needn’t
【例1】(2004年江苏卷)--- I don't mind telling you what I know.
--- You . I'm not asking you for it.
A. mustn't B. may not C. can't
