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

試題分析：考查情態(tài)動詞。根據(jù)told可知這里談?wù)摰氖沁^去的事了。橫線處的意思應(yīng)該是：也許當(dāng)初我應(yīng)該給她寫出來。這樣的話，選C. should have done表示：本來應(yīng)該做某事，而實(shí)際上沒有做。  must have done表示：過去肯定過去某事。故C正確。
