高考英语总复习：状语从句
状语从句在高考试题中由于其他从句的干扰，以及倒 装句，强调句的介入，使得状语从句更为复杂。状语从句 是一种副词性从句，通常由一个从属连词或一个起连词作 用的词组引导。
1. 时间状语从句 常见的连词(组)：
when, while, as, before, after, once, till, until, as soon as, n, scarcely ...when, no sooner ...than等。
It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ② 不等……就……； 在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③ 刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。 ④ 先……再…… You can have a few days to think about it before you make your decision. 做决定之前你还有几天时间考虑。
注意点如下： (1) when, while, as引导的时间状语从句 as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句 的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某 一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生 也可以先后发生。while强调一段时间，仅表示从句和主句的动作同时发生，并且有 延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般 过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。

不可用as或when，这里的while意思是“趁……”)一、when可以和延续性动词连用，也可以和短暂性动词连用；而while和as只能和延续性动词连用① Why d yu want a new jb when yu've gt such a gd ne already？（get为短暂性动词）你已经找到如此好的工作，为何还想再找新的？②Srry，I was ut when yu called e．（call为短暂性动词）对不起，你打电话时我刚好外出了③Strie while the irn is ht．（is为延续性动词，表示一种持续的状态）趁热打铁④ The students t ntes as they

／As she was aing a phnecall，I was writing a letter．（ae为延续性动词）当她在打电话时，我正在写信3．当主句、从句动作同时进行，从句动作的时间概念淡化，而主要表示主句动作发生的背景或条件时，只能用 as这时，as常表示“随着……”；“一边……，一边……”之意① As the tie went n，the weather gt

telephne ring他刚进屋电话铃就响了④先……再……Yu can have a few days t thin abut it befre yu ae yur decisin做决定之前你还有几天时间考虑(3)since 引导的从句用延续性动词的过去式（包括过去完成时）时，则从句的动作已经结束,从句意思是否定的如果从句的动词是延续性动词的现在完成时态，则从句意思是肯定的He has never been t see e since I was ill我病愈后，他一直未看我（不再生病了）He has never been t see e since I have been ill我病了，他一直未看我I haven t heard fr hi since he lived here自他从这里搬走，我就没有收到他的信（不住在这儿了）(4) till,

语气最弱，其原因只是对结果的附带说明，一般放在句首fr虽然解释为“因为”但只是一个并列连词，它也常引导句子表示原因，但不是原因状语从句，它是一个并列句fr所提供的理由是一种补充性的说明，表示推测的理由nw that意为“既然，由于”表示由于人们已知的事实或正在发生的事而产生某个结果He failed because he was careless他因粗心而失败了Since everyne has ce, let s begin ur eeting既然大家都了，我们开会吧As all the seats were full, he std there所有的座位都满了,他只好站那儿It ight have rained last night fr the grund is wet昨晚可能下雨了，因为地面是湿的Nw that the ids have left he we have a lt f

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)，ha rdly…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。
高中英语2025届高考语法复习状语从句知识讲解
高考英语语法复习状语从句知识讲解一、概述常见的有although/though/even though引导的让步状语从句。
if/unless引导的条件状语从句。
until/when/while/as soon as引导的时间状语从句。
because引导的原因状语从句，so that引导的目的状语从句等。
if引导的条件状语从句和when引导的时间状语从句一般都会和时态相结合，即主要考查“主将从现”原则。
对于状语从句的学习可与专题六从属连词相结合。
在时间状语从句和条件状语从句中，主句和从句的时态一致问题一般有两种情况：（1）“主将从现”：主句用一般将来时，而从句用一般现在时。
常见的使用“主将从现”原则的连词有：表示时间的when, while, after, before, until, till, whenever, as soon as, as long as, once 等；表示条件的if, unless, so long as, in case等。
（2）“主祈从现”：若主句是祈使句，或主句中有情态动词时，那么从句用一般现在时表示将来。
（3）“主情从现”：若主句有情态动词, 那么从句用一般现在时表示将来。
如：You can get good grades if you study hard.如果你努力学习，你将取得好成绩。
状语从句由从属连词引导,与主句连接,位于句首时,常用逗号与主句分开,位于句末时,其前一般不用逗号。
状语从句根据其用途可分为时间状语从句、条件状语从句、原因状语从句、目的状语从句、结果状语从句、让步状语从句、比较状语从句、地点状语从句等。
二、时间状语从句(1)当主句是一般将来时态或祈使句,表示将来的意义时,从句通常用一般现在时,简称“主将从现”。
I’ll ring you up as soon as I get to Beijing.我一到北京就给你打电话。
(2) when引导的时间状语从句,通常表示主句和从句的动作同时发生;before表示主句的动作发生在从句的动作之前;after则表示主句的动作发生在从句的动作之后;as引导时间状语从句时,往往表示主句和从句的动作同时发生,不分先后。
