I told Sally how to get here, but perhaps I ______for her. A．had to write it outB．must have written it out C．should have written it outD．ought to write it out

Answer 1

【答案】C
【答案解析】试题分析：考查情态动词。根据told可知这里谈论的是过去的事了。横线处的意思应该是：也许当初我应该给她写出来。这样的话，选C. should have done表示：本来应该做某事，而实际上没有做。
must have done表示：过去肯定过去某事。故C正确。
