1.【2015·湖南】24.Video games can be a poor influence if ________ in the wrong hands.
A. to leave B. leaving
C. leave D. left
【答案】D
【考点定位】考查状语从句中的省略问题。
【名师点睛】一般说来省略现象多出现在下列五种状语从句中:由 when ,while ,as ,before, after , till, until, once等引导的时间状语从句；由whether ,if , unless 等引导的条件状语从句；由 though , although ,even if ,whatever等引导的让步状语从句；由 as ,than 等引导的比较状语从句；由as, as if , as though 等引导的方式状语从句。上述状语从句在省略时，并非任何成分都可以省略而是遵循下面原则：（1）当状语从句的主语与主句的主语一致时且从句中含有be动词的某种形式时，可以省略状语从句的主语和系动词be 。（2）当从句的主语与主句的主语不一致，但从句主语是 it，从句中又含有系动词be 的某种形式时 ，可以把it和系动词be一起省略。此题的形式属于：连词(when ,if ,even if ,unless ,once ,until, than , as ) + 过去分词 。完整的句子就是：Video games can be a poor influence if they are left in the wrong hands.
