Question

I told your friend how to get to the hotel, but perhaps I ________ have driven her ther.

1. A.
   could
2. B.
   must
3. C.
   night
4. D.
   should

Answer 1

D
思路分析：should have done sth表“本应该干某事而实际上却没有干”。could have done表“本可以干某事”；must have done表“一定干了某事”；might have done表“可能干某事”。据题意“但或许我本应该开车把他送到那儿去”。因此选D。
点评：该题考查情态动词表推测的用法，难度偏难。考生应注意情态动词表推测时的具体含义，且注意表示对过去事情的推测时，情态动词后一律用have done的形式。
