I told Sally how to get there , but her 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 课本答案是A,对吗？在网上查答案多是C

Answer 1

答案C
本句译为“我告诉了Sally怎样去那儿，但也许我本应该替她写下来(实际上没写)．这是表示“本应该做而实际上未做”，该用should/ought to+have done．

Answer 2

是对的，have to：不得不；我已经高数Sally如何去那里，但恐怕我不得不在纸上写下来给她。

Answer 3

C should have done sth.表示本该做某事却未做。
