题目内容
I told Sally how to get there, but perhaps I ________ for her.
A.had to write it out
B.must have written it out
C.should have written it out
D.need to have written it out
【答案】
C
【解析】
试题分析:考查情态动词+完成式的用法:句意:我告诉Sally怎么到这儿,但是可能我应该把它写下来。本应该做而没做should have done,must have done过去一定做了,need 后面直接接have done,没有to,选C。
考点:考查情态动词+完成式的用法
点评:情态动词无论是表达“推测和可能性”,还是表达“虚拟”这一概念,只要是对过去已经发生的事情进行描述,一律用“情态动词+have done”这一结构;对现在或将来的事情进行描述,用“情态动词+动词或系动词原形”。
