Question

【题目】I told Sally how to get here, but perhaps I _______ for her.

A. had to write it out B. must have written it out

C. should have written it out D. ought to write it out

Answer 1

【答案】C

【解析】句意：我告诉Sally如何到达这里，但是也许我应该给她写出来。A. had to write it out不得不把它写出来； B. must have written it out一定把它写出来了，表示对过去的一种推测，说话的语气很肯定；C. should have written it out应该把它写出来，表示过去应该做的事情而没有做； D. ought to write it out应该把它写出来。表示现在应该把它写出来。should have done实际上是说话人在表达责备，抱怨或遗憾的意思。根据I told Sally how to get here可知，“告诉”发生在过去，那么写出来也应该发生在过去，表示过去应该做的事情没有做，应该用should have done或ought to have done，故选C。
