Question

The man we followed suddenly stopped and looked as if ________ whether he was going in the right direction.

A．seeing 　　　 B．having seen 　　　　　　 C．to have seen 　 D．to see

 

Answer 1

D

原句应为“as if he stopped and looked to see whether...”，由于从句和主句有相同的主语和谓语，故将从句的主语、谓语同时省略，而只留下目的状语“as if to see”。
