状语从句中的省略讲义-高考英语语法专题复习

1、状语从句中的省略在表示时间、地点、条件、方式（比较）或让步等的状语从句中，如果谓语动词含有动词be，主语又和主句的主语一致，或其主语是it，那么从句中的主语和谓语的一部分（尤其是be动词）往往可以省略。使用这些省略结构可收到言简意赅之功效。（一）从属连词+名词例句：Though (he was) a youngman, he has written three famous novels.虽然年轻，但他已经写了三本著名的小说了。例句：When (he was) still was aboy of six, Bob was sent away from home.鲍勃才六岁时就被送出家门。例句：

6、（=He stared at me as if he had saw me for the first time.）注意！As在引导时间状语从句时，其后不能运用省略形式，此时用when、while替代。例句：When/While living in London, I picked up English. （不能用As）在伦敦居住期间，我学了一点英语。（七）从属连词+动词的-ed形式例句：When (it is)taken according to the directions, the drug has no side effects.按照说明服用，这种药就没有副作用。例句：When (it
