高考英语必考语法专题之状语从句语法详解及强化练习

完整版)高中英语状语从句讲解及练习状语从句是指在句中作状语的从句，可以分为时间、条件、让步、原因、目的、结果、比较、地点、方式状语从句。

时间状语从句的连词有when、as、while、until、not…until、before、after、since、the minute、the moment、each、every、next、the first time等。

时间状语从句一般使用一般现在时或一般过去时。

当使用when、as、while这三个连词引导时间状语从句时，它们都表示“当…的时候”，但侧重点有所不同。

例如，当使用when引导时间状语从句时，从句的主语与主句主语相同，如果谓语动词是be动词，则从句主语和be可以省略。

而as则不仅表示“当…的时候”，还可以表示“一面…一面”或“随着”。

而while则强调主句的动作和从句的动作同时发生，从句一般用进行时，从句动词必须是延续性动词。

当使用until、not…until时，它们表示“直到…才”。

在肯定句中，主句常用延续性动词；在否定句中，主句常用短暂性动词。

需要注意的是，当not until…位于句首时，主句需要倒装。

例如，“Not until you had explained how did I manage to do it.”It was dark when he finally returned。

XXX the machine type upon seeing it。

As soon as I arrived home。

it began to rain。

Hardly had I arrived home when it began to rain。

XXX: real XXX: if。

even if/though。

unless/if。

not。

as long as/so long as。

as far as/so far as。

provided/providing(that)。

备战高考英语语法状语从句讲解及真题45题状语从句状语从句在句中作状语，修饰主句中的动词、形容词或副词等。

状语从句放在主句之前时，常用逗号分开：放在主句之后，一般不用逗号。

状语从句按其意文和作用可分为时间、条件、原因、让步、目的、结果、方式、比较、地点等九种。

时间状语从句时间状语从句常用连词有when，as，while，before，after，since，till（until），as soon as，hardly…when…，no sooner…than，the moment等。

时间状语从句一般不用将来时，因此，主句若为将来时，时间状语从句要用一般现在时。

如：I'll go on with the work when I come back tomorrow.一、when, while与as的异同作为从属连词，三者的意思都是“当…时候”，在用法上有如下异同点。

1.在主句的谓语动词表示短暂动作，而从句说的是一段时间发生的动作时，三个连词都可以。

如：I met him as／when／while I was doing some shopping.2.从句动作发生的时间如果是某一点，而且主句动作同时或几乎同时发生时，不能用while，而只能用when或as。

如：I met him as/when I was getting off the bus.3.当从句动作发生在主句动作之前时，只能用when，如：I will ring you up when I return.4.主句用进行时态，从句动作发生的时间如果是某一点，只能用when。

如：My mother was cooking the supper when I got home.5.如果主句和从句的动作都在一段时间发生，可用as或while，只不过as强调主句和从句中的动作同时发生，而while强调主句的动作延续于while所指的整个时间。

状语从句一、知识框架二、知识梳理（一）定义在复合句中修饰主句中的动词、形容词和副词的从句叫状语从句。

状语从句根据它表达的意思不同可分为时间状语从句、地点状语从句、条件状语从句、比较状语从句、目的状语从句、结果状语从句、方式状语从句、让步状语从句和原因状语从句等。

状语从句如果放在主句前通常用逗号分开，放在主句之后一般不用逗号。

（二）九类状语从句一）时间状语从句1、从属连词分类1）基本类包括when, while, as, whenever, before, after, since, till, until, once (一旦), as soon as等。

Did anyone call when I was out?We have known each other since we were children.You’ll feel better after you take the pills.Make sure that all the lights are off before you go to bed.2）名词类包括the moment, the minute, the second, the instant, every time, each time, (the) next time, the last time, any time, the first time等。

高中英语状语从句专项讲解及练习（有答案）状语从句1、地点状语从句地点状语从句表示地点、方位，这类从句通常由where, wherever, anywhere, everywhere引导。

Where there is a will, there is a way.有志者，事竟成。

They will go where they are happy.他们想到他们觉得快乐的地方去。

We must camp where we can get water. 我们必须在能找到水的地方露营。

地点状语从句与定语从句的区别:在于分句在句中作什么成分。

作状语，则是状语从句；作定语修饰名词，则是定语从句。

where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。

如：Go back where you came from.(where引导地点状语从句）Go back to the village where you came from.(where引导定语从句，修饰village)We went home, where we had dinner. (where引导定语从句，修饰home)2、原因状语从句原因状语从句一般由because(因为)，since(既然)，now that(既然，因为)，as(由于)等连词引导。

（1）because表示直接的原因，表示原因的语气最强，常表示必然的因果关系。

回答why引起的特殊疑问句，只能用because。

Jane wore a raincoat because it was raining.因为天下雨，所以詹穿着雨衣。

He is absent today because he is ill.他今天缺课，因为他病了。

（2）since表示对方已经知晓、无须加以说明的原因或事实，语气比because稍弱。

I'll do it for you since you are busy.既然你忙，我来替你做吧。

状语从句可位于主句之前，也可位于主句之后。

状语从句可分为时间、地点、原因、结果、条件、方式、让步、比较和目的等九大类。

在使用的时候，要根据句子结构和句意来判别和区分不同的从句，正确使用引导词。

以where为例，试比较下列多种从句的区别。

You are to find it where you left it. (地点状语从句)Tell me the address where he lives. (定语从句，先行词为the address)I don’t know where he came from. (宾语从句)Where he has gone is not known yet. (主语从句)This place is where they once hid. (表语从句)(2)在两个分句间要有一个且只有一个连词，千万不能按汉语习惯。

状语从句1. 在主从复合句中修饰主句中的动词，形容词，副词等的从句叫状语从句。

可分为，时间状语从句，地点状语从句，原因，目的，结果，条件，让步，比较和方式状语从句。

2. 时间状语从句起时间状语作用的句子；可放在句首，句中和句尾常用引导词：when，while, as, after, before, since, till, until, the moment, hardly … when , no sooner … thanwhen, while, as的用法1) when 用法最广，常可代替while和as, 在while 引导的从句中，动词只能是延续性的When the fire broke out, all the students were sleeping soundly.The telephone rang while I was taking a bath.2) 当两个表示时间延续的动作同时发生而又有对比意味的时候，用while，在这样的复合句中，主句从句的时态通常是相同的。

Father was preparing a report while I was playing PC games.3) 常用as的情况：一边…一边；表示随着短暂动作的发生，另一行为伴随发生As he talked on, he got more and more excited.They talked as they walked along the river.My cap was blown away as I sat down.until和till的用法表示“一直到…”时，主句和从句都用肯定式；I will wait until/ till the concert is over.表示“直到…才…”是，主句用否定，从句用肯定式。

此时可与when互换。

如：Please keep quiet while/when others are studying. 当别人正在学习时，请保持安静。

(2) when除可指一段时间外，还可用来指时间点，等于“at the time”，即when引导的时间状语从句中的谓语动词可以是瞬间的，也可以是持续性的。

状语从句2.在复合句中作状语，位置灵活。

3.状语从句可分为时间状语从句，目的状语从句，条件状语从句，让步状语从句，地点状语从句，原因状语从句，方式状语从句，结果状语从句。

10.Eg：When〔youare〕introuble,youcanaskherforhelp.11.如果when引导的时状的主语与主句的主语相同时，往往可以用“when+分词〞的形式代替该状从。

12.Eg：WhenIcameintotheroom(Whencomingintotheroom),Ifoundthelightwasoff.13.while表时间，从句需用延续性动词，或者主句的动作发生在从句的动作进行过程中。

主句的谓语动词通常是非延续性动词。

14.Eg:HecameinwhileIwasreadingabook.15.ImetherwhileIwasinschool.16. c.as表时间，与when相似，但侧重强调主从句动作同在时间点或同时间段进行。

同时可表示主句的动作随着从句的动作的变化而变化。

17.Eg:Hejumpsashesings.18.Asthewindrose,thenoiseincreased.19.before(在之前)与after〔在之后〕Eg：Seemebeforeyouleave.20.IsawthemafterIarrived.21.till与until肯定形式表示的意思是"做某事直至某时 "。

2020届高三高考英语复习语法讲解及练习题：状语从句【含答案】重难点分析状语从句是由从句担任状语，在句子中可修饰谓语动词（或其他动词）、形容词、副词或整个句子。

它可以用来表示时间、地点、条件、原因、结果、目的、让步、比较、方式等。

状语从句是一个较大的语法项目，也是近几年高考题中常见的重点考点。

高考中已考查了时间、让步、地点、条件、目的等状语从句，这些从句仍是今后高考的热点，应做充分的准备。

同时对方式状语从句也应引起重视。

不同的状语从句所使用的连接词也各不相同。

如下表所示：状语从句名称连接词时间状语从句when, as, while, whenever, after, before, till/until, since, once, as soon as/the moment, by the time, no sooner…than, hardly…when, every time等地点状语从句where和wherever条件状语从句if, unless, as long as, on condition that, if only(=if)原因状语从句because, since, as, now that(既然)结果状语从句so that(从句谓语动词一般没有情态动词), so…that, such…that目的状语从句so, so that(从句谓语常有情态动词), in order that, in case(以防，以免)让步状语从句although, though, as(常用倒装结构), even if/though, however, whatever, whether…or, no matter who(when, what, where…)等比较状语从句than, as…as, the more…the more方式状语从句as, as if/though, the way, rather than等一、时间状语从句1. while, when, as引导时间状语从句时的区别(1) while引导的状语从句中谓语动词必须是持续性动词。

【高中语法·状语从句专辑】状语从句和名词性从句、定语从句一样是高考的高频考点。

通过对近年高考题的分析，可以预测2012年对状语从句的考查仍将集中在对引导几大状语从句的连词的考查上。

状语从句是一种作状语用的从句，修饰主句中的动词、形容词、副词或修饰全句，补充说明时间、地点、原因、条件、方式、程度、状态等。

状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。

九种状语从句及常见的引导词1、【时间状语从句】：when, while, as, before, after, since（自从…以来）, till (until), as soon as(刚一…马上就…), once(一旦), whenever等。

特殊引导词：the minute, the moment, the second, every time, the day，the instant=instantly , immediately , directly, no sooner … than, hardly …when, scarcely … when (1) while 引导的时间从句的谓语必须是延续性动词，常用进行时态。

如果while表示“然而”的时候，就不是时间状语从句；表示“虽然”的时候，是让步状语从句，这是必须放句首且不能倒装。

(2) when 除了表示“当……时”（两个短暂性动作同时发生），还可以表示“就在那时”，在前一个动作刚结束时就发生的新动作。

如I just locked my door when the postman arrived.(3) as 和when一样，表示两个短暂性动作同时发生，还可表示“一边……一边……”“随着…”(4) 党表示“一……就……”的连接词时，可以用到no sooner … than, hardly …when, scarcely … when，但是当hardly, scarcely, no sooner放于句首时，主句必须部分倒装；主句时态用过去完成时，从句用一般过去式。

高中英语状语从句练习与讲解状语从句状语从句在句中相当于副词做状语,又叫副词性从句。

状语从句分为时间状语从句、条件状语从句、地点状语从句、原因状语从句、目的状语从句、让步状语从句、结果状语从句和比较状语从句。

掌握状语从句应当引导词入手，注意引导词的词义,引导状语从句的引导词都有词思,所以,了解引导词的意思尤为重要。

引导词按意义分为九类:1)时间when , as , while , till , until , before, after , since2)地点where3)原因because , as , since , now that4)条件if , unless , once .so (as)long as . in case5)让步though , whatever (--ever) as, even though, even if6)目的so that, in order that7)结果so ... that8)比较than, as .. as9)方式as , as if例如:1．I fell asleep when ( as , while ) he was doing his exercises .他正作练习时我睡着了。

1)WhenEg: When I arrived home , I had a little rest.注意点：when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be可以省略。

Eg: When (she was) walking along the street, she met her class teacher.2)AsAs 除了表示“当```的时候”，还可表示为“一面```一面”，“随着”Eg: He sang as he danced.(一面```一面)You will grow wiser as you grow older.(随着)3)While表示“当```的时候”强调主句的动作和从句的动作同时发生，从句一般用进行时，从句动词必须是延续性动词。

eg: I prefer black tee, while he likes coffee.2．until, not…until表示“直到```才”,在肯定句中主句常用延续性动词；在否定句中主句常用短暂性动词。
