选择题
The man we followed suddenly stopped and looked as if _____ whether he was going the the right direction.
A.seeing
B.having seen
C.to have seen
D.to see
答案
答案:D
题目分析:考查非谓语动词。句意:我们跟踪的那个人突然停下四处张望,好像是为了确认他走的方向是否正确。这里考查动词不定式表示目的,stopped and looked to do sth停下来张望是为了做......,stopped, looked和see三个动作是同时发生的,因此不用不定式的完成时,排除C,故选D。
