题目

We__________have proved great adventurers,but we have done the greatest march ever made in the past ten years.

A.needn't
B.may not
C.shouldn't
D.mustn't

参考答案和解析

答案：B

解析：

考情点拨：本题考查情态动词一应试指导：句意：我们也许没有被证明是伟大的探险家，不过我们的前进是过去十年来最伟大的。“may not+现在完成时”表示“也许没有”，用于对过去或已经发生的事进行猜测。“needn’t+现在完成时”表示“本来没有必要”，表示过去不需要做某事：“shouldn’t+现在完成时”表示“本来不应该做而做了某事”。mustn’t不与现在完成时连用，只与动词原形连用，表示“禁止，不要”。
