状语从句一、概述：状语从句修饰主句中的动词、形容词、副词等，在复合句中作状语。

二、用法：（一）时间状语从句的用法：1、注意点：⑴在时间、条件状语从句中，谓语动词一般不用将来时态表示将来，而用一般现在时态代替一般将来时态，用一般过去时态代替过去将来时态，用现在完成时态代替将来完成时态。
如：When he comes here，I will let you know. When I have finished reading the book，I will tell you.注意：when可以引导时间状语从句，还可以引导宾语、主语等名词性从句；if可以引导条件状语从句，也可以引导宾语从句（引导条件状语从句时，意为“如果，假如”，引导宾语从句时，意为“是否”）；注意当它们引导时间和条件状语从句时，要用一般现在时态表示将来，引导宾语等名词性从句时，仍然要用一般将来时态表示将来。

高考英语状语从句知识点知识点复习高考英语状语从句知识点复习状语从句是高考英语中的重要语法知识点之一，掌握好状语从句对于理解和运用英语语言有着至关重要的作用。
在这篇文章中，我们将对高考英语中常见的状语从句类型进行详细的复习。
一、时间状语从句时间状语从句表示时间关系，常用的引导词有 when（当时候）、while（在期间）、as（当时，一边一边）、before（在之前）、after （在之后）、since（自从）、until ／ till（直到）等。
When 引导的时间状语从句，表示一个动作发生时，另一个动作正在进行或刚刚完成。
例如：“I was doing my homework when my mother came back” （当我妈妈回来的时候，我正在做作业。
）While 引导的时间状语从句，强调主句动作和从句动作在同一时期内同时发生，且持续时间较长。
例如：“While I was reading, my sister was playing the piano” （我在读书的时候，我妹妹在弹钢琴。
）As 引导的时间状语从句，强调两个动作同时发生，或一个动作随着另一个动作的变化而变化。
例如：“As time goes by, we are growing older” （随着时间的流逝，我们渐渐变老了。
）Before 和 after 引导的时间状语从句，分别表示“在之前”和“在之后”。
例如：“Please turn off the light before you leave the room” （在你离开房间之前，请关灯。
）“I will call you after I finish my work” （我完成工作之后会给你打电话。
）Since 引导的时间状语从句，表示“自从以来”，主句通常用现在完成时，从句用一般过去时。
例如：“I have lived here since I was born”（自从我出生以来，我就住在这里。
高考英语二轮复习时间、地点、条件状语从句考点总结讲义（基础篇）状语从句状语从句又叫副词从句，用途非常广，却非常简单，简单到中学学习时都没有费太多笔墨，为什么？因为状语从句都有非常明显的代表某种逻辑的标志词，这些标志词总共有九类，也就意味着状语从句分为九种。
分别为：时间、地点、条件、原因、结果、目的、让步、方式、比较。
首先，我们先明确一些理念。
状语从句和并列句的比较1. I am going to leave the party early so that I can get a good night’s sleep.（我要早点离开聚会，那样的话我就能好好睡一觉。
）2. I am going to leave the party early and I want to be able to get a good night’s sleep.（我要早点离开聚会，我要好好睡一觉。
）句1是一个复句，有主句有从句，so that引导的状语从句和前面的主句都是完整、独立的简单句，中间用so that连接；句2是和个合句，逗号前后都是完整的简单句，由一个并列连词and连接，需要注意and两边的句子没有主从之分，相互也不需要解释。
句1这个状语从句由从属连词so that连接，使得so that I can get a good night’s sleep的地位下降，成了前面主句的附属句，当副词使用（目的状语），用来修饰主句“离开聚会早”的目的是“回家好好睡一觉”。
总的来看这两个句子，状语从句的从属连词给句1带来了从属关系，除开这层修饰关系，状语从句和句2的并列句并无二致，同样表意单纯。
状语从句和名词性从句3. The witness said that he saw the whole thing.（证人说他目睹了事情发生的全过程。
）4. The witness said this, though he didn’t really see it.（证人这样说，尽管他没有真正看到。
1.状语从句概念？状语从句指句子用作状语时，起副词作用的句子。
状语从句在高考中考察基本是以翻译从句引导词为主。
2.分类以及各个从属连词用法？2.1时间状语从句(when，while，as, no t…until, since,before……)when，while，as区别：while用引导的动作必须是持续的，侧重于主句动作和从句动作相对比e.g I was cooking at noon while she was sleeping.as“一边…一边…”或着“随着”e.g He was looking behind as he walked.As times flies, the weather is getting cooler and cooler当主句表达短暂性动作，而从句表示一段时间内的延续性动作时，.用三者都可以I met Jim when/while/as I was riding in Heping Road.其他：as soon as, immediately, directly, the moment, the instant, once(一…就…)The boy burst into tears immediately he saw his mom.I will leave here as soon as I get my visa.(主将从现：if/as soon as/when/until 引导的时间状语从句)no sooner…than…; hardly…when…; scarcely…when…(一…就…, 但含有否定意味的词置于句首时，主句要部分倒装)(hardly…before…; scarcely…before…)主句用过去完成时，从句用一般过去时。
I had hardly got home when it began to rain.Hadly had I got home when it began to rain.No sooner had we reached at school than the bell went.till/untill(直到till不可以用于句首), not…until（直到…才…）注意not until强调句用法和倒装句用法。
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。

高考英语语法专题汇总：状语从句(附练习及答案)状语从句在句中作状语，可分为：时间、条件、让步、原因、目的、结果、地点、比较、方式状语从句。
1时间状语从句引导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。
时间状语从句中一般用一般现在时或一般过去时。
1．when , while, as都可解释为“当```的时候”但侧重点有所不同。
1) When后既可以接短暂性动词，也可以接延续性动词，表示从句动作与主句动作同时发生。
When I arrived home , I had a little rest.2）As 除了表示“当```的时候”，还可表示为“一面```一面”，“随着”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。
While we were working, they were having a rest.While (they were) having a discussion, they got very confused.注意：while 有对比的含义，解释为“然而”。
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；在否定句中常用短暂性动词。
肯定句：I waited until midnight. 否定句：I did not leave until midnight. 注意点：1）not until…在句首，主句用倒装 Not until you had explained how did I manage to do it.2) It is not until…that…引导的强调句 It was not until it was dark that he came back.3．Hardly/scarcely…when, no sooner…than, as soon as表示为“一```就```”I had hardly/scarcely got home when it began to rain.I had no sooner got home than it began to rain. It began to rain as soon as I got home.2条件状语从句条件状语从句分为两大类：真实条件句（主将从现）和虚拟条件句（虚拟语气）。
时间/地点/条件/让步/原因/结果状语从句讲解2022届高考英语语法总复习时间状语从句状语是在句子中修饰动词、形容词、副词等的句子成分，用于表达时间、地点、原因、目的、结果、条件、让步、方式、比较的句子成分。
每一种状语从句都有相对应的引导词如:时间引导词: when, whenever, while, since, as, until, once, as soon as等。
He was pretty ambitious when he was young. 在他年轻的时候，他相当有野心。
Whenever I come to this park, it would remind me of my carefree childhood.(每当我来到这个公园，我都会回忆起我无忧无虑的童年。
)While his wife was busy cooking in the kitchen, he was watching TV in the living room.他妻子在厨房忙于做饭的时候，他在客厅看电视。
(既表示动作同时进行，也形成鲜明对比。
)As the day went on, the weather got worse. (随着时间天气变得更糟了。
)since引导的时间状语有一个特殊的点需要指出，先看例句:It is five years since I smoked.应翻译为:我戒烟已经五年了。
(It is +时间段+since 后所接动词是延续性动词表示时间从该动作结束那一刻开始)。
I have smoked for five years.我已经吸烟五年了。
地点状语从句地点状语从句就是一个从句在句子中表示地点、方位的句子。
常见引导词:where, wherever anywhere, everywhere.1，where引导的状语从句Where there is a will, there is a way.有志者，事竟成。
I found my book where I lost it.我在书丢的地方找到了它。
I shall meet him where I first met him.我将在我第一次见他的地方去见他。
2，wherever引导的地点状语从句Wherever you go, I will be right here waiting for you.无论你去哪里，我都在这里等你。
I will go wherever I want .我想去哪儿就去哪儿。
3，anywhere 引导的地点状语从句I will take you anywhere you like.我将会带你去任何你喜欢的地儿。
4，everywhere 引导的地点状语Everywhere they appeared, there were ovations.他们每到一处都收到热烈欢迎。
条件状语从句条件状语从句就是指两个句子是”条件与结果“的关系：事件A导致了事件B。
如果A，那么B，A就是条件，B就是结果。
例如句子：如果没有网络，生活将会很枯燥。
如果所有人都乘坐公共交通的话，道路就会畅通很多。
只要你开心，其他任何事都不重要。
引导条件状语从句的引导词（组）主要有if, unless, so (as) long as, on condition that, so (as) far as, if only ( = if )。
If there were no Internet, life would be very boring.If all commuters take public transportation, the traffic will be much smoother.As long as you are happy, nothing else matters.条件状语从句：表示将来会发生的事，”主将从现“。
表示客观事实或习惯性动作，”主现从现“。

If we run the system for free, there will be less money for the daily expenses.如果我们免费运作这个系统，将会削减人们的日常开销。
让步状语从句“让步”就是退一步来讲，仍然成立。
比如我非常爱打篮球，一般风和日丽的放学午后约三五好友去操场打球是很爽的。
但对于我来说，即使天气条件糟糕的很，是阴天，是雪天，我也一如既往去打球(即使最差条件也接受）。
或者一般好看的都有对象，但对于某些人，虽然他帅气多金，依然是黄金单身汉。
有担当的人会说无论出什么事情，我们愿意承担全部责任。
这些由“即使”，“虽然”，“无论”所引导的句子都是在做出“让步”。
引导让步状语从句的连接词有：although, though, even if, even though, as, 疑问词+ ever ，no matter + 疑问词. as引导让步状语从句要半倒装。
Even if my body coordination is poor, I am fascinated with dancing.即使我身体协调性差，我还是喜欢跳舞。
Much as he disagreed with the idea, he was willing to go along with the majority.尽管他很不同意这个观点，但是他还是愿意随大流。
Child as he is, he knows a lot.虽然他是个孩子，但他懂得很多。
Although (though) he was over sixty,(yet) he began to learn French .虽然他60多岁了，但仍开始学习法语。
No matter who takes up the matter for me, I shall be very grateful.不管谁为我出来这件事，我都将非常感激。
原因状语从句常见的原因状语引导词：because, as, since, for, now that, seeing that等。
because从句所表示的是对方不知道的直接的原因，因此在回答why引导的特殊疑问句时只可用because, 语气最强。
eg.Why were you late for class today?(今天为什么迟到了？）--Because my alarm clock didn't go off this morning.（因为今早我的闹钟没响）I am really into watching American sitcom mainly because it is beneficial for boosting my English level. 我喜欢看美剧最主要的原因就是它可以提高我的英文口语水平。
语气最强，所以常用于强调句。
It is because he is witty that we all like him.正是因为他非常诙谐幽默所以我们都很喜欢他。
2. since 表示既然或者全已知的理由，稍加分析即可表明的原因，多放于句首。
语气较之弱一点。
Since everyone is ready, let's begin it.既然每个人都准备好了，我们开始吧。
Since I used to be a nerdy man, I' d like to have a healthier life by doing some sports.因为过去过着一种书呆子生活，所以想通过做运动过得更健康些。
3. as 引导的原因状语从句，as从句常放在句首，说明原因，主句说明结果，常用于口语中。
As it's raining outside, you'd better take a taxi.既然外边下雨了，你最好打个车。
It is a very popular tourist destination, especially for families,as it brings history for the children.它是一个非常受欢迎的旅游目的地，尤其是对家庭来说，因为它为孩子们展示了栩栩如生的历史4. for往往用于附加理由证明，对前面一句进行解释，有时表示其理由具有推测性。
一般放句尾。
We listened carefully, for the speech was very important.我们认真听讲因为这个演讲很重要。
The day gets long, for it is summer now.白天变长因为现在是夏天了。
5. seeing (that), now that 和since, as 意义相似，他们都有“鉴于某个事实”的意思，that可以省去Seeing that I live further uptown than you, I could, theoretically, pick you up.鉴于我住得比你远，理论上，我可以捎带你一程。
Now that he understood, he anger faded away.既然她明白了，她的怒气就消了。
结果状语从句结果状语从句是相对较为简单的一类状语从句。
常用连词so that, so...that; such...that 引导的句子。
常译为：如此……以至于。
1. so that 前一般有逗号，表示其引导的是结果状语从句而非目的状语从句。
We turned up the radio, so that everyone heard the news.我们调高了收音机音量，结果每个人都听到了。
He spoke at the top of his voice, so that the students at the back heard him.他说话声音很大，结果后面的同学都听到了。
The room was packed with people, so that we couldn't get in.房间里挤满了人，结果我们进不去。
2. so +adj/adv+that... 也就是说so 后边只能跟形容词和副词。
