状语从句
状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句，原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。
1. 时间状语从句
(1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。例如：It was raining hard（rain hard 下大雨）when got to school yesterday.
While he was doing his homework, the telephone rang.
As he walked along（沿着走）the lake, he sang happily.
He had learned a little Chinese before he came to China.
After he finished middle school, he went to work in a factory.
(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如：
I’ll ring you up as soon as I get to New York.
I will tell him everything when he comes back.
He won’t believe it until he sees it with his own eyes.
(3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。例如：
The young man read till the light went out（熄灭）.
Let’s wait until the rain stops.
We won’t start until Bob comes.
Don’t get off（从下来）until the bus stops.
【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。Until 是指直到某一特定事件发生的时候，而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止（不怎么可能持续）。固定组合里from morning till night，till/until是不能替换的，】2. 条件状语从句
(1)条件状语从句通常由if, unless引导。例如：
What shall we do if it snows tomorrow?
Don’t leave the building unless I tell you to.
(2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如：
I’ll help you with your English if am free tomorrow.
He won’t be late unless he is ill.
(3)“祈使句+ and (or)+ 陈述句”在意思上相当于一个带有条件状语从句的复合句。例如：Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late.
Study hard and you will pass the exam. =If you study hard, you will pass the exam.
3. 原因状语从句
(1)原因状语从句通常由because, since, as引导。例如：
He didn’t come to school because he was ill.
As it is raining, we shall not （不得；不应该）go the zoo.
Since you can’t answer the question, I’ll ask someone else.
(2)because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since语气较弱，一般用来表示明显的原因。由as 和since引导的原因状语从居多放在句首。例如：
------Why aren’t going there?
------Because I don’t want to.
As he has no car, he can’t get there easily.
Since we have no money, we can’t buy it.
(3)because和so不能同用在一个句子里。
4. 结果状语从句
(1)结果状语从句由so…that, such…that, so that引导。例如：
He is so poor that he can’t buy a bike for his son.
She is such a good teacher that everybody likes her.
My pencil fell under the desk, so that I couldn’t see it.
(2)so…that语such...that可以互换。例如：
在由so...that引导的结果状语从句中，so是副词，与形容词连用。其结构是: “...so + 形容词（副词）+ that + 从句”。例如：
He was so glad that he couldn’t say a word.
The hall is so big that it can hold 2,000 people.
Mother lives so far away that we hardly ever（几乎不，从来不）see her.
在由such…that引导的结果状语从句中，such是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词；名词前面可以带形容词，也可不带。如果是单数可数名词，前面需加不定冠词a或an。例如：
It was such a hot day that nobody wanted to do anything.
He had such long arms that he could almost touch the ceiling.（天花板）
He made such rapid progress that he did very well in the mid-term.
有时上述两种结构是可以互换的。例如：
It was such a wonderful film that all of us wanted to see it again.
=The film was so wonderful that all of us wanted to see it again.
It is such an important match that nobody wants to miss it.
=The match is so important that nobody wants to miss it.
(3)如果名词前由many, much, little, few等词修饰时，只能用so, 不用such。例如：
Soon there were so many deer that they ate up all the wild roses.
He has so little time that he can’t go to the cinema（去看电影）with you.
5. 比较状语从句
比较状语从句通常由as…as, 比较级+ than…等连词引导。例如：
Tom runs faster than John does.
This classroom is as big as that one.
6. 目的状语从句
(1)目的状语从句通常由so that, in order that（为了，以便）引导。例如：
We started early so that we could catch the first train.
He studies hard so that he could work better in the future.
We used the computer in order that we might save time.
(2)so that既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：1)目的状语从句里往往带有情态动词can, could, may, might等。2)从意思上看，目的状语从句往往表示的目的很明确。例如：
Speak clearly so that they may understand you. (目的状语从句)
Jack is badly ill so that he has to rest. (结果状语从句)
7. 让步状语从句
(1)让步状语从句通常由although, though等连词引导。例如：
Though he is young, he knows a lot.
Although I am tired, I must go on working.
(2)although(though)不能用在同一个句子中。例如：
我们不能说：Though it was raining hard, but he still went out.
应该说：Though it was raining hard, he still went out.或It was raining hard, but he still went out. 8. 地点状语从句
地点状语从句常常由where来引导。例如：
Go where you like.
Where there is a will, there is a way.
总结：状语从句分类及常用连词：
类别连词
时间状语从句when, whenever, while, as, before, after, since, till, once（一旦）

状语从句 状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句，原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。 1. 时间状语从句 (1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。例如：It was raining hard（rain hard 下大雨）when got to school yesterday. While he was doing his homework, the telephone rang. As he walked along（沿着走）the lake, he sang happily. He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory. (2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如： I’ll ring you up as soon as I get to New York. I will tell him everything when he comes back. He won’t believe it until he sees it with his own eyes. (3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。例如： The young man read till the light went out（熄灭）. Let’s wait until the rain stops. We won’t start until Bob comes. Don’t get off（从下来）until the bus stops. 【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。Until 是指直到某一特定事件发生的时候，而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止（不怎么可能持续）。固定组合里from morning till night，till/until是不能替换的，】2. 条件状语从句 (1)条件状语从句通常由if, unless引导。例如： What shall we do if it snows tomorrow? Don’t leave the building unless I tell you to. (2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如： I’ll help you with your English if am free tomorrow. He won’t be late unless he is ill. (3)“祈使句+ and (or)+ 陈述句”在意思上相当于一个带有条件状语从句的复合句。例如：Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如： He didn’t come to school because he was ill. As it is raining, we shall not （不得；不应该）go the zoo. Since you can’t answer the question, I’ll ask someone else. (2)because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since语气较弱，一般用来表示明显的原因。由as 和since引导的原因状语从居多放在句首。例如： ------Why aren’t going there?

初中英语条件状语从句语法详解 (名师剖析语法知识点+ 实战训练题，值得下载打印) 一．条件状语从句的概念 条件状语从句，即在某种条件下，一件事情可能发生。在英语中由连接词if或unless等 引导的状语从句叫做条件状语从句。条件是指某一件事情实现之后（状语从句中），一件事 情（主句）才能发生，通常译作“假如，只要，如果”等意思。条件状语从句中，主从句的时 态要遵循“主将从现”的原则。即，主句是将来时态时，从句用一般现在时代替将来时态。 二.条件状语从句的引导词 1.If conj . 如果，假如 If you ask him，he will help you．如果你请他帮忙，他会帮你的。 If you fail in the exam，you will let him down．如果你考试不及格，你会让他失望的。 2.unless conj.除非,若不,除非在……的时候（if ...not...） You will fail to arrive there in time unless you start earlier. 如果你不早点动身,你就不能及时赶到那儿。Unless it rains, the game will be played. 除非下雨,比赛将照常进行。 3.so/as long as conj.只要 You may borrow my book as long as you keep it clean. 只要你保持书的清洁，你就可以把我的书借去。 三．关于条件句的时态，常见的有以下三种情况： 1、条件状语从句的主句是一般将来时，那么从句常常用一般现在时。 When I grow up, I’ll be a nurse and lo ok after patients. 我长大后要当一名护士，照顾病人。 2、如果主句是祈使句，那么从句通常要用一般现在时。 If you want to have a chat ,call me up. 如果你想聊天，打我电话。
（一）状语从句概述 定义状语从句用作状语，是起副词作用的句子。 位置状语从句可以放在主句之前，也可以放在主句之后，时间、条件、原因和让步状语从句放在句首时需要用 逗号和主句隔开。 分类根据其作用可以分为时间、地点、原因、条件、目的、让步、方式和比较等状语从句。 作用它可以修饰谓语、非谓语动词、定语、状语和整个句子。 （二）状语从句详解 1. 时间状语从句 引导词用法示例 when 意为“当…的时候”。When 引导从句的谓语动词可以 是延续性动词，也可以是 瞬间动词。并且when有 时表示“就在那时”A liar is not believed when he speaks the truth.说谎者讲真话时也没有人相信。When he arrives, I’ll call you. When you laugh and smile, your body relaxes. while 意为“在…的时候，在…的 同时”。While引导从句的 谓语动词必须是延续性While I was standing at the window, I saw several boys running along the street.
的，发生时间较长，并强调主句和从句的动作同时发生（或者相对应）。While 有时还可以表示对比。While John was watching TV, his wife was cooking. as 意为“一边…一边…”。As 引导的动作是延续性的， 发生时间较短，一般用于 主句和从句动作同时发 生；as也可以强调一前一 后。The writer was angry as he was travelling on a train to London because someone had invaded his “space”. He smiled as he stood up. after 意为“在…之后”。表示主句 动作发生在从句动作之 后。主句与从句的动作时 间关系与before引导的从 句相反。With many hungry visitors waiting, don’t stay too long at your table after you have finished. If an early exit is necessary, you can leave after a scene is over. before 意为“在…之前”。引导的从 句不用否定形式的谓语， 并且当before引导的从句 位于主句之后，有时译成 “就，才”。当主句用将来时，You can’t watch TV before you finish your homework.

中考英语状语从句专题训练答案及解析 一、初中英语状语从句 1．—Tom wants to know if you ___ a picnic next Sunday. —Yes. But if it ___， we'll visit the museum instead. A．will have; will rain B．have; rains C．have; will rain D．will have; rains 【答案】D 【解析】 试题分析：句意：汤姆想知道下周你是否要去野餐。——是的，但是如果下雨，我们就会去参观博物馆。结合语境可知上文是宾语从句，描述的是将来发生的动作，故用一般将来时态。下文是条件状语从句，当主句为一般将来时态时，条件状语从句中用一般现在时态表示将来的动作，结合语境可知选D。 考点：从句中的时态 点评：英语宾语从句的时态和主句没有必然的联系，需结合语境进行具体分析。而英语状语从句的时态与主句有比较紧密的联系，若主句为一般将来时，时间和条件状语从句通常要用一般现在时表示将来，而不能直接使用将来时态。 2．---Would you like to go bike riding with us tomorrow? ---Sure, ____ I am busy. A．since B．unless C．when D．until 【答案】B 【解析】 试题分析：句意：----你想要明天和我们一起去划船吗？好的，如果我不忙我就去。A自从；B如果不；C当……时候；D直到……才。根据句意，应选B。 考点：考查连词。 3．--- Do you know what time Daniel Xuzhou tomorrow? ---At 2:00 p. m. I will meet him when he at the airport.

第章状语从句 学习指导 状语从句在句子中作状语，用来修饰主句或主句的谓语。一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比 较和方式。尽管种类较多,但由于状语从句与汉语结构和用法相似,所 以理解和掌握它并不难。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。现分别列举如下: 状语从句分九类： 在这一章节的学习中，要求同学们掌握各类状语从句基本概念，并能够灵活应用。 第一节时间状语从句 时间状语从句用一般现在时表示将来。连接时间状语从句的连接词有：2．when，while，as均可表示“当……的时候”。 when强调“特定时间”，表示主句谓语动词的动作与从句谓语动词的动作是同时发生的，或从句的动作发生在主句的动作之前；while表 示的时间是一段，而不是一点，as多用在口语中，强调“同一时间”或“一前一后”，有时还有“随着”的含义。 When spring came, he felt like a trip.春天来了，他想去旅游。 As spring warms the good earth，all flowers begin to bloom．(as有“随着”的含义) as, when, while都表示主、从句的动作或状态同时发生，但三者也有
区别。as和when引导的从句既可表示一点时间，也可表示一段时间，从句中的谓语动词既可以是持续性动词，也可以为短暂性动词，经常可以互换使用；while引导的从句通常表示一段时间，从句中宜用持续性动词作谓语。当从句中的谓语动词为持续性动词时，这三者可以通用（前面例句中已有体现），再如： 1 / 18 Mother was worried because little Alice was ill, especially as / when / while father was away in France.妈妈担心，因为小艾丽思病了，特别是当父亲远在法国的时候。 如果从句和主句要表示一个人的两个动作交替进行或同时完成时，则多用as，可译为“一边......，一边......”。例如： He looked behind from to time as he went.他一边走，一边不时地往后看。 As time goes on, it's getting warmer and warmer..随着时间的推移，天气变得越来越暖了。 I thought of it just as you opened your mouth.你一张嘴我就知道你要 说什么。（若表示两个短促动作几乎同时发生时，用as的场合多于when.） 当主从句之间表示转折或对比关系时，多用while, 不用as或when。如：

A．Although B．Once C．If 【答案】A 【解析】 【详解】 句意“尽管今天是公共节假日，但是我们城市的一些消防员仍然在岗位值班”。A.尽管（引导让步状语从句）；B.一……就……（引导时间状语从句）；C.如果（引导条件状语从句）。根据句意可知，今天是公共假日，本应该休息，但是消防员仍然在岗值班，表示让步，故选A。 2．— _______ good time we had at the party last night! — Yes. It was _______exciting party that I would never forget it. A．What; so B．How; such C．What a; such an D．How a; so an 【答案】C 【解析】 【详解】 试题分析：句意：昨天晚上我们在聚会上玩的是多么开心呀！是的，它是如此的令人兴奋以至于我永远不会忘记它。 第一句为感叹句，是对 a good time表示感叹，time为名词，所以用what来引导，第二句考查such+a/an+adj+n.+that句型结构，表示“如此……的一个东西……以至于”，故选C。 3．-Have you improved your spoken English？ -Not yet．I'll try my best______I am not good at it now． A．so B．although C．but D．until 【答案】B 【解析】 【详解】 句意：——你提高你的英语口语了吗？——还没有．虽然我现在还不擅长，但是我会尽力的．考查连词辨析。A. so所以；B. although 虽然；C. but但是；D. until直到。根据语境推测句意是——你提高你的英语口语了吗？——还没有．虽然我现在还不擅长，但是我会尽力的．在这里两个句子之间存在一个相反的让步关系，though/although/even though“虽然；尽管”，引导让步状语从句，故选B． 【点睛】 本题主要考查连词的用法，连词在句子中主要起联系上下文的作用，他们之间的区别就是表示逻辑关系的不同，所以在解题时先要理解上下文含义，然后根据上下文逻辑关系选择合适的连词．前后句之间是让步关系．
状语从句 状语从句修饰主句/主句的谓语。一般有九大类：表示时间、地点、原因、目的、结果、条件、让步、比较和方式等。 时间状语从句 1. 用when引导：when表示“当……时候”。如： Things were different when I was a child. 我小时候情况与现在不同。 People breathe more slowly when they are asleep. 人睡觉时呼吸比较缓慢。 2. 用while引导：while表示“当……时候”。如： We must strike while the iron is hot. 我们要趁热打铁。 I went swimming while the others played tennis. 我去游泳，其余的人都打网球去了。 注意：while 所引导的时间状语从句中谓语动词必须是持续性的，不能是短暂性的。 3. 用as引导：as表示“当……时候”“随着”。如： He dropped the glass as he stood up. 他站起来时，把杯子摔了。 We get wiser as we get old. 随着年岁的增长，我们也变得聪明些了。 4. 用before引导：before表示“在……之前”。如： Turn off the lights before you go to bed. 睡觉前要关灯。 Before he went to university he was a worker. 上大学之前他是工人。 5. 用after引导：after表示“在……之后”。如： I will tell you after they leave. 他们走我再告诉你。 After you finish the letter show it to me．信写完后给我看看。 6. 用until / till引导：until / till表示“直到……”。如： He waited until she was about to leave. 他等着一直到她准备离开。 I watched him until he disappeared in the distance. 我瞧着他直到他在远处消失。 这类句型的主句动词通常只能是延续性动词，不能是终止性动词。但是，在否定句中，主句动词可以是终止性动词，此时构成not…ntil [till]…句式，意为“直到……才……”。如：
