以下是小编为大家分享的高考英语状语从句语法，一起来看看吧。
状语从句 Adverbial clause
状语从句可修饰谓语、非谓语动词、定语、状语或整个句子。
表示：地点、时间、原因、条件、目的、结果、让步、行为方式、比较等。
as, when, while的区别
while用于时间较长时，强调两个动作同时进行，并表示对比;
as用于发生时间较短时，表示一边、、、一边、、、的意思;
when可以表示从句动词的动作在主句动词的动作“之前”或“之后”发生。
表原因的状语从句，since作“既然”解时
Since everybody is here, let’s begin.
Now that they have taken matters into their hands, the pace of events has quickened. 因为
表示目的、结果的状语从句
so that; so…that都可以引导目的状语从句和结果状语从句，区别在于：
1. 当它们引导目的状语从句时，从句的谓语里常有can, could, may, might, will, would等词;
2. 而当引导结果状语从句时则没有上述这些词，而且从内容上看主句和它们引导的结果状语从句有因果关系，主句为因，从句为果。
I’ll run slowly so that you can catch up with me. 目的
He ran slowly so that I caught up with him. 结果
He always studies so hard that he may make great progress. 目的
He always studies so hard that he made great progress. 结果
