状语从句讲解和练习
状语修饰动词、形容词、副词或整个句子。通常由副词、介词短语、动词不定式、分词和从句等担当。例如：
1. Naturally , our grandparents were pleased to get our phone call . (副词)
2. We worked hard , from sunrise to sunset . (介词状短语)
3. To help my disabled aunt , I spend an hour working in her house every day . (不定式)
4. Seen from a distance , the farmhouse looked deserted . (过去分词)
5. I know how to light a camp fire because I had done it before .（原因状语从句）
状语的位置比较灵活，可以位于句首、句末或句中。enough用作状语修饰形容词和副词时必须后置。
状语从句主要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
和特殊的连接词即考点。现分别列举如下:
1．时间状语从句

10. 状语从句的简化
?状语从句的省略
状语从句同时具备下列两个条件:①主句和从句的主语一
致，或从句主语为it；②从句主要动词是be的某种形式。从句中的主语和be动词常可省略。例如：When ( the museum is ) completed , the museum will be open to the public next year .
He’ll go to the seaside for his holiday if (it is ) possible.
另外，比较状语从句经常省略。例如：
I’m taller than he (is tall ).
The higher the temperature (is), the greater the pressure (is ).
就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行"简化"。状语从句的"简化"现象在口语中较为普遍,而且在高考中的复现率也较高。因此,有必要对其进行全面、透彻的了解。
状语从句的"简化"现象常存在于以下五种状语从句中:①由if, unless等引导的条件状语从句;②由althoug h, though, even if / though等引导的让步状语从句;③由when, while, as, before, after, until / till等引导的时间状语从句;④由as, as if等引导的方式状语从句;⑤由as, than等引导的比较状语从句。下面针对这五种情形作一归纳。
(1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉。例如:
If (it is) possible, he will help you out of the difficulty.如果可能的话,他会帮你摆脱困境。
You must attend the meeting unless (it is) inconvenient to you.除非情况对你来说不方便,否则你必须
出席这次会议。
(2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉。常用于以下几种情形:
a.连词+形容词
As (he was) young, he learned how to ride a bike.他小时候就学会了骑自行车。
Whenever (she is) free, she often goes shopping.她有空就去逛商店。
Work hard when (you are) young, or you'll regret.少壮不努力,老大徒伤悲。
b.连词+名词
While (he was) a young boy, he was always ready to help others.他在孩提时代就乐于助人。Although (he was) a farmer, now he is a famous director.尽管他曾是个农民,而现在是位著名的导演了。
c.连词+现在分词
As (she was) walking along the river bank, she was singing a pop song.她沿着河堤边走边唱着流行歌曲。
Although (he is) doing his best in maths these days, he has still got no good marks.尽管近来他一直在学数学,但他仍然没有取得好成绩。
d.连词+过去分词
He won't go there with us unless (he is) invited.除非受到邀请,否则他不会和我们一道去那里。
The concert was a great success than (it was) expected.这场音乐会出乎意料地取得了巨大成功。
e.连词+不定式
He stood up as if (he were) to say something.当时他站起来好像要说什么。He wouldn't solve the pro blem even if (he were) to take charge.即使他来负责,他也解决不了这个问题。f. 连词+介词短语
She looked anxious as though (she was) in trouble.她看上去很焦急,好像遇到了麻烦。
He had mastered the English language before (he was) in the USA.他到美国之前就懂英语了。
注意:当从句主语和主句主语不一致时,从句部分要么用完全形式,要么用独立主格结构来表达。例如: When the meeting was over, all the people went out of the meeting-room.当会议结束时,人们都走出了会议室。(=The meeting over,

状语从句 在复合句中担任状语成分的从句称为状语从句，修饰主句的谓语动词，形容词或副词，状语 说白了就是修饰动作的词或句，也可以理解成修饰谓语的词或句。通常由副词、介词短语、 动词不定式、分词和从句等担当。例如： 1. Naturally, our grandparents were pleased to get our phone call. (副词 ) 2. We worked hard, from sunrise to sunset. (介词状短语 ) 3. To help my disabled aunt, I spend an hour working in her house every day. (不定式 ) 4. Seen from a distance, the farmhouse looked deserted. (过去分词 ) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 状语的位置比较灵活，可以位于句首、句末或句中。enough 用作状语修饰形容词和副词时 必须后置。 状语从句主要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 和特殊的连接词即考点。现分别列举如下: 1．时间状语从句 常用引导词： when, as, while, as soon as, while, before, after, since , till, until 特殊引导词： the minute, the moment, the second, every time, the day ， the instant, immediately , directly, no sooner ? than, hardly ? when, scarcely ? when I didn ’ t realize how special my mother was until I became an adult. While John was watching TV , his wife was cooking. The children ran away from the orchard( 果园 ) the moment they saw the guard. No sooner had I arrived home than it began to rain. Every time I listen to your advice, I get into trouble. When , while, as 都可解释为“当```的时候”但侧重点有所不同。 1) When Eg: 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) As As 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: While we were working, they were having a rest. While (they were) having a discussion, they got very confused. 注意点： while 有对比的含义，解释为“然而”。 eg: I prefer black tee, while he likes coffee. 1．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。
高中英语状语从句用法详细解析 一、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。 二、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 三、时间状语从句 （一）引导时间状语从句的连词有：as, when(whenever), before, after, as soon as, until(till), since, every time, once. （二）、“as” as, when, while都有“当……的时候”，可以互用When she was a child. While she was a child. She Lived in Paris. As she was a child. as有“一边…一边”的意思 He sang as he walked. “when” When the clock struck twelve, all the lights went out. I was sleeping when she came in. 动补 When we arrived at the station, the train had left. “while” 主、从句动作或状态同时发生。用while引导的从句用延续性动词，常表示较长的时间或一个过程。 While we were having supper, all the lights went out. Please keep quiet while others are studying. While I was writing letters last night, he was watching TV. when, while并列连问。when和while都可用作并列连问，连接并列分句。When表示“就在……的时候”, while意反而，可是，表示转折。
状语从句 一、时间状语从句 1、when, while, as 和whenever when 表时间点，时间段 while 表时间段；有“而”的意思 as “当……”,“一边……一边”，“随着……” whenever 每当，无论什么时候 It is cold when it snows. While there is life, there is hope. While we were speaking, he was reading newspaper. Just as Mrs Richards was entering the dinning-room, there was a knock on the front door. As we age, we trade strength for ingenuity, speed for thoroughness, and passion for reason. 随着年龄的增长，我们用力量换来了机敏，以速度换来了严谨，以热情换来了理智。 注：1)when还可作并列连词，其意义为“那时，这时”，相当于and at this/that time。常用于下列句式： sb.was doing sth.when...某人正在干某事就在这时…… sb.was about to/ going to do sth.when...某人正打算干某事就在这时…… sb.body has just done sth.when...某人刚干了某事就在这时…… 2)如果主句表示的是短暂动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作时，when，while 与as可互换使用。如： When/While/As I was walking down the street，I came across an old friend of mine. 2、before/ after It will be five years before we meet again.五年之后我们才能见面。 After you think it over, please let me know what you decide. After her husband had gone to work, she sent her children to school. 3、until, till, not...until 1)肯定句：主句的谓语是延续性动词，主从句均为肯定式，意为“某动作一直持续到某时间点才停止”
专题十一状语从句 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。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副（介）词（短语）或名词短语： directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 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。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 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。
高中英语状语从句讲解汇总 原因从句 除了下面A2，A3中所示各种类型外，这两种从句均可由as或because来引导。但是用as引导原因从句较为稳妥（参见A）；用because引导结果／原因从句较为稳妥（参见B）。 A 原因从句 1 由as／because／since 引导的原因从句： We camped there as／because／since it was too dark to go on． 我们在那里露宿是因为天太黑，不能再继续往前走了。 As／Because／Since it was too dark to go on，we camped there． [ 因为天太黑不能再继续往前走，我们就在那儿露宿了。 2 in view of the fact that可用as／since／seeing that来表示，但不能用because： As／Since／Seeing that you are here，you may as well give me a hand． 既然你在这儿，你就帮我个忙吧。 As／Since／Seeing that Tom knows French，he’d better do the talking． 既然汤姆懂法语，最好让他来谈。 3 在as／since／seeing that意指以前共知的或共知的陈述时，可用if来代替： ~ As／Since／Seeing that／If you don’t like Bill，why did you invite him 既然／如果你不喜欢比尔，你为什么邀请了他 注意：if so的用法： —I hope Bill won’t come． —If so（＝If you hope he won’t come），why did you invite him —我希望比尔别来。 —如果这样（=如果你希望他不来），你为什么邀请了他 关于if＋so／not，参见第347节。 ~ B 结果从句由because或as引导： The fuse blew because we had overloaded the circuit． 保险丝烧断了，因为我们使线路超载了。 He was angry because we were late． 他生气是因为我们来晚了。 As it froze hard that night there was ice everywhere next day． 因为那天晚上冷得厉害，所以第二天到处都是冰。 ~ As the soup was very salty we were thirsty afterwards． 因为这汤很咸，后来我们渴得厉害。
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：
时间状语从句 用句子表达一件事情或一个行为发生的时间，这个句子就叫时间状语从句。时间状语从句根据其所表示的时间不同，所使用的连词也不同。下面我们一起来看一下几个常见的时间状语从句： 1．when引导的从句：表示主句的动作和从句的动作同时发生，或从句的动作发生在主句动作之前。 例如：I was going out when a visitor came. (动词动作同时发生。)我正要出门，有客人来访。 I shall tell her the good news when she comes.她来时，我将告诉她这个好消息。 小试牛刀：I found mother cooking for me. I got home.(when)_______________________________________ He was listening to the radio when I home. (get) 2．while 引导的从句：表示“当……过程中”，强调某一段时间内主句和从句中谓语动词所表示的动作在同一时期发生。由于while从句表示一个持续的行为，所以从句中要用持续性动词，并且持续性动词常用进行时态。例如：Keep an eye on my little sister while I am away.我不在时，请照看一下我的小妹妹。 While we were watching TV, Jim came in. 我们看电视的时候，Jim进来了。 小试牛刀：It started to rain. We were playing football.(while)_______________________________________ Lucy was cleaning the room Lily was listening to music. 3．as引导的时间状语从句：表示“当……的时候；一边……一边……；随着……”，其从句的主语与主句的主语往往是同一人或物。 例如：She sang as she worked. 她一边工作一边唱歌。=She was singing as she was working. I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。 小试牛刀：we walked, we talked. You will grow wiser you grow older. 4．before引导的从句：一般表示主句的动作发生在从句动作之前。 例如：I didn’t know any English before I came here. 我到这儿来之前，一点英语都不懂。 例如：I had written my report before my father came back. 小试牛刀：He bought the ticket he went to see the film. 5．after引导的从句：表示主句的动作发生在从句动作之后。 例如：After he locked the door, he left. 他锁上门后，就走了。 After he had finished his work, he played a game of chess with his friend. 他做完工作后，和朋友下了一盘棋。小试牛刀：I will go out to play basketball with you. I finish my homework.(after) _______________________ _ He left the classroom he had finished his homework the other day. 6．since引导的从句：表示“自从……以来”，从句中的动词一般表示动作的起点，用过去时。主句中的动词表示动作延续的情况，一般用现在完成时。如果主句中的动词表示的不是延续的动作而是表示目前的状态，可用一般现在时。 例如：Since he met this good friend, he has made great progress in his studies. 自从遇见了这个好朋友，他已在学习上取得了巨大的进步。 例如：It is twenty years since she joined the Party. 她入党二十年了。（主句中的动词表示的是状态，用现在时。）小试牛刀：it is five years since we last time.（meet） Mr green has taught in that school since he (come) to China three years ago. 7．until 引导的从句：表示一个动作持续到某一时刻。 （1）表示“直到……”，如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。（2）表示“直到……才”，主句用否定式，从句用肯定。如果主句中的谓语动词是瞬间动词时，必须用否定形式。
高中状语从句讲解+练习 状语通常由副词、介词短语、动词不定式、分词和从句等担当。例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，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和特殊的连接词即考点。现分别列举如下: 1．时间状语从句 常用引导词：when, as, while, as soon as, while, before, after, since , till, until 特殊引导词：the minute, the moment, the second, the instant, immediately , directly, every time, the day，no sooner …than, hardly …when, scarcely …when （1）Tell him I need to see him the minute he arrives. 他一到就告诉他我要见他。 （2）The children ran away from the orchard(果园) the moment they saw the guard.
