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.热心网友 时间:2024-10-21 17:00
