状语从句的省略 状语从句的省略有如下规律：1.省略与主句相同的状语、表语、部分谓语等句尾部分,一般不可以只省略主语或全部谓语部分,或只省略助动词.例如：I'll go fishing,if you will （ go fishing ） .2.when,while,as,if,as if,though 等引导的时间、条件、方式、让步状语从句时,若从句中的主语与主句的主语一致,则可以连同后面的 be 动词一起省去.例如：Even as （ he was ） a child,he began to learn French.While （ he was ） at college,Jackson wrote a novel.If （ he were ） alive,he must be at least ninety years old now.The old man looked around,as if （ he was ） in search of something.3.在 whether 引导的让步状语从句中,表示时间的 it is / was 可以省略.例如：Whether （ it was ） summer or winter,his clothes were always dirty.4.if 引导的从句中的 it is 也可省略； if not 可以表示与前面相反的情况.例如：If necessary,please call me.Are you busy this afternoon?If not,I'd like you to help me.
