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。

高考英语语法复习：八种状语从句的用法状语从句状语从句有时间、地点、原因、目的、方式、结果、条件、让步等八种。

一、时间状语从句：引导词有after，before，as，once，since，till，until，when，whenever，while，as soon as，the moment/minute…(一…就)，the time,the day,every time,next time,each time，by the time of，no sooner…than(一…就)，hardly…when(一…就).例如：Each/Every time he comes here,he will drop in on me.每次他来这儿他都顺便看我.He was ill last time I saw him.上次我见到他时他病了.No sooner had she heard the news than she cried.她一听到这个消息就哭了.[辨析]when与whilewhen引导的从句动词可以是延续性的或短暂性的，while引导的从句中动词必须是延续性的;在“be…when…”句式中when表“at that time(就在这时)”意，这样用的when不能换为while;while有时并不表示时间，而表示对比，意“而”、“却”，when无这样的用法。

例如：When I got home I found the door locked./While(或When)we were working in the fields,it suddenly began to rain./He was wandering through the streets when a bike hit him./His pencil is red,while mine is yellow.[辨析]till与until一般情况下可以互换，但until可以位于句首，till则不能。

二、专题详解状语从句梳理知识点1：分类语从句可以分为以下九种：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、结果状语从句6、条件状语从句7、方式状语从句8、让步状语从句9、比较状语从句知识点2：具体用法1) 时间状语从句：as soon as Hardly/scarcely had…whenNo sooner had …than….the moment.. the instant…the second…immediately directly…instantly…①As soon as I arrive in Shanghai, I’ll writeto you.我一到上海就给你写信。

④We had just begun the moment wewere told to stop.我们刚开始就被叫停。

⑤I felt cheerful immediately I heard thesong.我一听到这首歌就感到很愉快。

①hardly…when和nosooner…than的意义相当于as soon as，但只表示过去发生的事情，主句为过去完成时，从句为过去时，如hardly或no sooner位于句首时语气强，而且主句的谓语要用部分倒装。

②名词短语连词：“一……就……”主句+ the moment…从句主句+the instant…从句主句+the second…从句③ 副词短语连词：主句+ immediately +从句主句+ directly +从句主句+ instantly+从句every time =each time last time…next time…the first time ①Every time I traveled by boat, I gotseasick.我每次乘船都晕船。

状语从句【知识精讲】状语从句,也叫做副词性分句，在主从复合句中起到状语作用，即把句子当作状语来使用，其作用类似副词，有时甚至可以用副词代替。

用以修饰主句的动词，形容词或副词，非限定动词〔不定式，-ing或 -ed分词〕或修饰整个句子。

表示时间，地点，方式，程度，原因，结果，目的，条件，让步和比拟等。

在高考英语中，状语从句主要出现在单句选择，改错或完型填空中。

一、状语从句的含义和类别1. 时间状语从句引导时间状语从句的连词主要有：when, as, while, as soon as, while; before, after, since, till, until; the minute, the moment, the second, any time, the day，the week, the instant, every time, each time, (the) next time,(the) last time, the first time; immediately , directly; no sooner...than, hardly...when, scarcely...when等。

〔1〕表示“当……时候〞或“每当〞的时间连词。

主要的 when, while, as, whenever。

例如：●He jumped up when the phone rang. 当响起的时候，他站起来了。

●We listened while the teacher read. 教师讲，我们听。

●They sang as they danced. 他们边唱边跳。

【注意】在高考中，我们主要要注意when表示“突然〞性，常用于“be+doing...when...〞，“be about to do...when...〞，“be on the point of doing...when...〞，“had just done...when...〞等句型中。
