(2009辽宁大连调研I ______ have been more than six years old when the accident happened.

A. shouldn’t        B. couldn’t       C. mustn’t         D. needn’t

试题答案

B

解析:

本题考查情态动词的用法。must表示推测只能用于肯定句,否定句用can或could 代替。shouldn’t have done 表示“本来不该而实际上却做了某事”.needn’t have done表示“本来不必而实际上却做了”均不合题意。本句的意思是:当事故发生时我不可能超过6岁。
