Question

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

C

解析:

根據(jù)句意“我已經(jīng)告訴她怎樣到那兒，但是或許我應(yīng)該給她寫下來”可知，說話者含有“后悔、遺憾”的意味，應(yīng)使用“情態(tài)動詞+完成式”形式，“must+完成式”表示對過去的肯定推測，“should+完成式”才表示虛擬意義。
