英语语法之 状语从句
高考英语重要语法知识：状语从句
高考英语重要语法知识：状语从句定义：在句中作状语的从句是状语从句，修饰主句中的动词、形容词或副词等。
状语从句由从属连词引导，从属连词在句中不充当句子成分，只起连接作用，状语从句放在句首时，要用逗号，放在句尾时不用。
分类：根据意义上的不同，状语从句可分为：①时间状语从句②地点状语从句③原因状语从句④目的状语从句⑤条件状语从句⑥结果状语从句⑦让步状语从句⑧方式状语从句⑨比较状语从句一、时间状语从句引导时间状语从句的连词有：as, when(whenever),while, before, after, as soon as, until(till), since,every/each/next time, once.（ as, when, while都有“当……的时候”，可以互用）◆When、While、as的区别：①when是at or during the time ,既指时间点，也可指一段时间，因此when引导的时间状语从句中的动词可以是终止性动词，也可以是延续性动词；while是during the time,只指一段时间，所以while从句中的动词必须是延续性动词。
②when说明从句的动作和主句的动作可以是同时，也可以是先后发生；when从句多用一般过去时while主从句动作或状态同时发生。
while从句多用过去进行时eg. When the teacher came in,we_____________________(talk).When the clock struck twelve,all the lights went out.When we arrived at the station,the train had left.While we _____________(have)supper,all the lights went out.While I was writing letters last night,he was watching TV.④when和while还可作并列连词when表示“就在那时”； while表示“然而”，表前后意思的对比。
