状语从句讲解和练习
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：
She didn’t marry until she was over fifty. 她直到五十多岁才结婚。
We’d better not go until your sister arrives. 我们最好等你姐姐到了再走。
7. 用since引导：since表示“自从……以来”。如：
We have known each other since we were children. 我们从小认识。
They’ve moved twice since they got married. 他们结婚后已搬了两次家。
这类句子的主句通常用现在完成时。但是，当主句表示一段时间时，可用一般现在时代替现在完成时。如：
It’s a long time since we met last. 好久没见面了。
How long is it since you came in London? 你来伦敦有多久了?
地点状语从句
地点状语从句多由where或wherever引起：
原因状语从句：
原因状语从句多由because，as，since，seeing(that)，considering that等连词引起：
他英语是讲得很好的。
以利用。
目的状语从句
表示目的状语的从句可以由that（以便），so that（以便），in order that（为了；以便），Lest（免得；唯恐），in case(以防)，for fear that（生怕；以免）等引导。
Lucy puts on her new skirt that she can receive others’ praise.Lucy为了获得他人的赞美，穿上了她的新裙子。
Mr Black eats four bowls of rice a day so that he can keep strong.为了保持强壮，Mr Black每天吃四碗饭。
I went to bed early in order that I could get up early.为了早起，我早早地就睡觉了。
I carried a bag of food lest there are no shops around.以防周围没有商店，我带了一包食物。
Lee takes more money in case the price of items is too high.以防物价太高，Lee带了很多钱。
He ran home as fast as he can for fear that it rains.他飞快地往家跑，生怕下雨。
结果状语从句
结果状语从句表示主句动作的结果，通常由so…that…或such…that…引导，例如：
a) I am so angry that I cannot speak a word. 我气的说不出话来。
b) I am such an angry man that I cannot speak a word. 我气的说不出话来。
细心的同学一定发现，so…that…和such…that…之间的微妙区别了吧？So后面加形容词或副词，而such后面要加名词或名词词组。例如：
a) He is so young that he can't go to school.他还太小不能上学。
b) He is such a young boy that he can't go to school.他还太小不能上学。
除此之外，so that也可以引导结果状语从句，例如：
a) I got up late this morning so that I missed the bus. 我早上起晚了，没看上公交。
有时候，so that可以省略其中的so或that。例如：
a) I got up late this morning so I missed the bus.
b) I got up late this morning that I missed the bus.
条件状语从句
常用引导词：if, unless, as/so long as 只要, only if只要, providing/provided that 假如, supposing that, in case that, on condition that。
条件状语从句的基本用法
1、用if引导：if意为“如果”。
例句：If you cheat in the exam you’ll never get away with it. 考试作弊必予追究。
2、用unless引导：unless的意思是“如果不”“除非”。
例句：Unless you go at once you will be late. 如果你不马上走，就会迟到的。
3、用as [so] long as引导：as [so] long as的意思是“如果”“只要”。
例句：I’ll remember that day as long as I live. 只要我活着，我就不会忘记那个日子。
4、用in case引导：in case用连词引导条件状语从句时，其意为“如果”“万一”。
例句：In case I forget, please remind me about it. 万一我忘记，请提醒我一下。
5、条件状语从句的时态：当主句为将来时态或含有将来意义时，条件状语从句习惯上要用一般现在时表示将来意义，而不能直接使用将来时态。
eg. I don’t know if it will rain tomorrow. But if it rains tomorrow, I’ll stay at home.不知道明天是否会下雨，但要是下雨的话，我就呆在家里。
让步状语从句
引导让步状语从句的连词主要有以下这些：though,although,while,as; even if,even though; whether...or...; no matter+疑问词，疑问词-ever，regardless of+名词/名词短语/名词从句，despite，in spite of。
① though，although：“虽然，纵然”，这两个连词意思大致相同，在一般情况下可以互换使用。在口语中，though较常使用，although比though正式，二者都可与yet，still或nevertheless 连用，但不能与but连用。
eg. I will go to school though it's too late now.
Although he was exhausted, he(still) kept on working.
Although/Though he is very old, (yet) he is quite strong.
② as（though）：“虽然…但是”，“纵使…”，as引导的让步状语从句必须以部分倒装的形式出现，被倒装的部分可以是表语、状语或动词原形，though也可用于这样的结构中。
eg. Object as/though you may, I’ll go.(=Though/Although you may object, I’ll go.) Fast as you write, you can’t finish your paper in only one night.
Lover of towns as I am, I realize that I owe a debt to my early country life.
③ whether：“无论，不论，不管”，由这一个复合连词引导的让步状语从句旨在说明正反两方面的可能性都不会影响主句的意向或结果，所以它的语气是比较强烈的。
eg. You'll have to attend the ceremony whether you're free or busy.
Whether you believe it or not, it's true.
Whether or not you like her, you have to become her husband.
④ no matter+疑问词=疑问词-ever：“……都……；不管……都……”
eg. No matter what happened, he would not mind. =Whatever happened, he would not mind.
⑤ whether...or...：“不论是否……”，“不管是……还是……”
eg. Whether you are rich or poor, the end result is the same, death
比较状语从句
引导比较状语从句的从属连词为as...as，not as/so...as，than，the more...the more 等等，这些都是用来进行比较对比，并且通常会与比较级最高级等连用。
The work is not so difficult as you imagine这个工作不像你想的那么难。
He is as handsome as that film star.他跟那个电影明星一样帅。
The more you study, the more knowledge you can get.你越学习就越能懂更多。
方式状语从句
引导方式状语从句的从属连词有as，as if 或as though等, 但和比较状语从句不同，方式状语从句的“像”“如同” 并不是表示单纯的比较，而是带有比喻或者依照的含义。
eg. Do as I told you.按我告诉你的那样做。
I remember the whole thing as if it happened yesterday. 整个这件事我记得很清楚，就仿佛是昨天发生似的。
As water is to fish, so air is to man.我们离不开空气，犹如鱼儿离不开水。
* 口语中like也可用连词引导方式状语从句。
eg. Do it like I do. 照我这样做。
I can’t dance like she does. 我没她舞跳得好。

初中英语时间状语从句讲解及练习
语法 29时间状语从句 一、什么是状语从句 状语就是在一句话中表示该句子的时间、地点、方式、原因、条件等成分。状语从句就是用一个从 句表示状语。状语从句根据它表达的意思不同，可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。 与状语一样，状语从句的位置比较灵活。既可置于主句之前（通常用逗号与主句隔开），也课置于主句之后（不需要用逗号与主句隔开），有时甚至可以置于主句之中。 二、时间状语从句 1. 主句和从句同时发生，这类从句由从属连词when, while, as引导。 He was hungry when he came home. I was crying while everyone was laughing. As I walked out, he walked in. as, when, while, 的区别 ① as强调从句的动作与主句动作同时发生及持续，具有at the same time的意思 他继续往下谈的时候，越来越兴奋。 as还可以表示一边??一边??，强调从句和主句中两个动作交替进行或同步进行。 他们边走边聊。 as还有“ 随着”的含义 随着春天的到来，天气暖和起来。 ② when 强调动作点的特定时间，具有at the time that 的意思 当老师走进来的时候，我们都站起来了。 ③ while 表示较长的期间，具有during the time that 的意思 当我在这的时候，我很安全。 2.主句发生在从句之前，这类从句由从属连词before, until 引导 ,before 意为“ 在---之前” until 在肯定句中意为“直到 --- 为止”，在否定句中意为“直到 --- 才”。从句既可置于主句前，也可置 于主句之后。 回家之前我必须干完所有的活。

高中英语状语从句讲解汇总
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。
时间状语从句讲解和练习
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.

状语从句讲解及习题附答案
（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. Before it ended, the theatre was almost empty. My father had left for Canada

when, while 和as 引导时间状语从句的用法 一、when 的用法 如果只从现象来看，when 从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。 1. When he was a child he was always trying out new ideas. 他小时候就常常试验一些新的设想。 2. When she came into my room, I was just reading a book. 她走进我房间时，我正在看书。 3. Were you writing when the teacher came in? 老师进来的时候，你在写信吗？ 4. Sorry, I was out when you called me. 对不起，你打电话来的时候我出去了。 5. He was on the point of leaving when someone knocked at the door. 他正要走，这时有人敲门。 6. I thought of it just when you opened your mouth. 就在你要说话的时候，我也想到了。 7. I had hardly[scarcely] closed my eyes when someone knocked at the door. 我刚一闭上眼，就有人在敲门了。
根据以上的例句，我们可以总结出一点：when 从句的A事件，相当于另一个事件B发生的时间点。也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，所以when 多数情况下用的是一般过去时，则不用正在进行时。因为如果用正在进行时，它表示的就是一段时间而不是一个时间点了。根据这一点，有的文章补充说：when 从句的动词大多是瞬时动词。 实际上，when 从句也可以有其它的时态，但几乎也不用进行时，因为它也只是作为一个时间参照点。 1. When I got to the airport, the guests had left. 当我赶到飞机场时，客人们已经离开了。 2. When he had finished his homework, he took a short rest. 当他完成作业后，他休息了一会儿。 3. Why do you want a new job when you have got such a good one already? 你已经找到如此好的工作，为何还想再找新的？ 4. You shall borrow the book when I have

As与when用法相似，但着重强调主句动作与从句动作同时发生，有"随着……"或"一边……一边……"之意。如： As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。 2．Because,as,since 的区别： Because用于表示直接原因,回答why提出的问题，语气最强；As用于说明原因, 着重点在主句，常译成"由于"；since表示显然的或已知的理由或事实，常译成"既然"。如： Water is very important because we can't live without it. He didn't come yesterday as his mother was ill. I'll do it for you since you are busy.

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：
