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
| D |
| 试题分析：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。 |
