1.时间状语从句

2. 条件状语从句

3. 原因状语从句

4. 结果状语从句

5. 比较状语从句

6. 目的状语从句

7. 让步状语从句

8. 地点状语从句

2.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 when got to school yesterday.

While he was doing his homework, the telephone rang.

As he walked along 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.

Let's wait until the rain stops.

We won't start until Bob comes.

Don't get off until the bus stops.

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.

t be late unless he is ill.

'He won

(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 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 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.

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。例如：such

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 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.

【实例解析】

1.You will stay healthy _______ you do more exercise, such as running and walking.

A. if

B. how

C. before

D. where

答案：A。该题考查的是引导状语从句的从属连词的选择。从意思上看，从句应是一个条件状语从句，在这四个选项中只有if能引导条件状语从句，所以选A。

2. ---Shall we go on working?

---Yes, _________ I prefer to have a rest.

A. when

B. if

C. because

D. though

A. when

B. until

C. after

D. though

“在……本句的意思是该题考查的是引导状语从句的从属连词选择。。B答案：以前我们没人知道这件事。”要表达着一意思应用“not…until”这一句型。 4.---I hope you'll enjoy your trip, dear!

---Thank you, mum. I'll give you a call _________ I get there.

A. until

B. as soon as

C. since

D. till

答案：B。该题考查的是引导状语从句的从属连词的选择。本题的意思是“一到那里，我就给你打电话。”要表达这个意思应选用as soon as。

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。

初中英语语法——If引导的条件状语从句(讲解及练习)

条件句从句主句真实一般现在时一般将来时情态动词+动原祈使句非真实一般过去时 be动词用（were） would/could+动原初中英语――条件状语从句（讲解&练习） Ⅰ条件状语从句的定义 Ⅱ条件状语从句的引导词 1.if引导的条件状语从句：表示在某种条件下某事很可能发生。 If we pay much attention to the earth, we'll have a better world. 如果我们多关爱地球，就会拥有一个更美好的世界 If it rains tomorrow, what shall we do? 如果明天下雨，我们怎么办？注意：if还可以引导虚拟条件句，表示不可实现的条件，从句中多用一般过去时或过去完成时。 What would happen if there were no water ? 如果没有水会怎样？ 2.unless引导的条件状语从句，unless的意思是如果不，除非。可与if...not互换。 You will fail in English unless you work hard. 你英语考试会不及格的，除非你更加努力。 3.as /so long as引导的条件状语从句：as /so long as意思是“只要” So long as you're happy,i will be happy. 只要你高兴，我就高兴。 Ⅲ条件状语从句的种类 Ⅳ条件状语从句的时态原则用法例句 ①主句为一般将来时态，if从句用一般现在时态（即主将从现）。We will stay at home if it rains tomorrow. 如果明天下雨，我将要呆在家。 ②主句中含有情态动词，if从句用一般现在时态。If you finish your homework, you can go home now.如果你做完了作业，你现在可以回家了。 ③主句为祈使句，if从句用一般现在时态。Don’t jump into the river if you feel very hot. 如果你感到很热，不要跳入河里。 ④主句为过去将来时，if从句用一般过去时态（如果涉及到be动词，一律都用were）。此时，表达的是和现实相反的推测，用虚拟语气。If I were you, I wouldn’t do it like that.如果我是你，我就不会那么做的。 If you gave me some money, I would be very happy. 如果你给我一些钱，我就会很高兴的。二、if 引导的条件状语从句（1）“if 从句+祈使句”的句子。其实，if 作为一个连词，主句也可以是其他形式的句子。例如：If you want to go, please let me know. (2)“祈使句 + and (or)+ 陈述句”

中考英语状语从句归纳

时间状语从句要点: 时间状语从句，由以下连词引导： when while as after before as soon as since till /until by the time 在时间状语从句中，要注意时态一致。一般情况下主句是将来时的时候，从句要用一般现在时。当。。。的时候 mozart started writing music when he was four years old. (当)莫扎特的时候，开始写音乐作品。当。。。时 he visited a lot of places while he was traveling.他在旅途中参观了许多地方。在。。。的同时；一边。。。一边。。。 he smiled as he stood up.他一边站起来一边笑着。在。。。之后 he left the classroom after he had finished his homework the other day. 前几天做完作业之后回的家。在。。。之前 mr. brown had worked in a bank for a year before he came here. 布朗先生来这之前已经在一家银行里工作一年了。 soon as 一。。。就。。。(主将从现) we began to work as soon as we got there.我们一到那就开始工作。 i will write to you as soon as i get home.我一到家就给你写信。自。。。以来到现在表示自过去的一个起点时间到目前(说话时间)为止的一段持续时间。主句一般用现在完成时，从句用一般过去时。 mr green has taught in that school since he came to china three years ago. 自格林先生来中国以来，他就在这所学校教书。 (还可以用作介词，本句从句还可以用短语：since three years ago(自三年前以来)表示。) 8 till /until都可以作连词，连接时间状语，也可以作介词，与其它词构成介词短语，在句中作状语。 they walked till /until it was dark.他们一直走到天黑。 xiao ming didn’t leave home till / until his father came back.小明直到他爸爸回来才离开家。 9. by the time 到。。。为止 (所在句子的主句应用完成时) by the time he gets there , his father has already gone.他到家的时候，他爸爸已经走了。 by the time i got to school, the class had already began.我到校时，已经开始上课了。难点——as when while的辨析 as when while都表示主、从句动作同时发生，三者差异如下： as 表示“一边。。。一边＂的意思强调两个动作同时进行，并表示对比时 when 1、还可以表示从句动词的动作在主几句动词的动作＂之前＂或＂之后＂发生。 2、when＝and then; at that moment (正在那个时候)

(完整版)初中英语语法专题(状语从句)讲解

初中英语语法专题（状语从句）讲解状语从句在复合句中作状语，修饰动词、形容词或副词等。状语从句可以表示时间、条件、原因、地点、目的、结果、让步、方式、比较等意义。知识梳理：提纲挈领，抓住重点和难点！各类状语从句连接词（短语）一览表：时间 when, while, as, as soon as, since, until, after, before 条件 If, unless 原因 As, because, since 地点 Where 目的 So that, in order that 结果So that, so…that, such…that 让步 though, although, even if, however 方式 As 比较 t han, (not)as…as, 时间状语从句： Whenever he comes, he brings a friend. 他每次来都带个朋友。条件状语从句： As long as I am alive, I will go on studying. 只要我活着，我就要学习。原因状语从句： Since we live near the sea, we enjoy nice weather.由于我们住在海边，能享受到好的天气。地点状语从句： Put it where we can all see it.把它放在我们都能看到的位置。目的状语从句：

Finish this so that you can start another.把这个做完，你可以开始另一个。结果状语从句： He was so angry that he couldn't say a word. 他气得说不出话了。让步状语从句： Though he is in poor health, he works hard.虽然他身体不好，但是他工作很努力。方式状语从句： Students do as the teachers say.学生们按照老师说的去做。比较状语从句： The work isn't as easy as I thought.这项工作比我想象得难。例题解析：举一反三，学的更轻松！ 1. 易混引导词while, when, as的区别： when既可以指"时间点",与瞬间动词连用，也可以指"时间段"，与延续性动词连用（=while）。如： When he came in, his mother was cooking. When (While) we were at school, we went to the library every day. While表示时间段,因此，while 从句的谓语动词要用延续性动词。如： Please don't talk so loud while others are working. 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.

初中英语状语从句知识点总结（一）用来修饰主句中的动词，形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导，与主句连接起来。若置于句末，则前面不加逗号。根据意义和作用，状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句时间状语从句常用从属连词when,after,until,as soon as,等来引导。当主句是祈使句或谓语动词是一般将来时态或情态动词时，其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。如：Please call me when you get there.当你到那时，请给我打个电话。 I will write to you as soon as I arrive in Beijing.我一到北京就给你写信。 <温馨提示>since引导时间状语从句表示“自从…以来”，从句中的动词一般表示动作的起点，用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为： It has been/is+一段时间+since+过去时。如：I has been/is three years since we met last time.自从我们上次见面，已经三年了。 2条件状语从句引导条件状语从句的连词或词组有：if(如果),unless(除非),as long as(只要)等。如果主句是将来时，条件状语从句也用一般现在时来表示。如：I will stay at home if it rains tomorrow.如果明天下雨，我就待在家。 You can’t learn English well unless you wo rk hard. 除非你努力学习，否则是学不好英语的。 <温馨提示>由if引导的条件状语从句，若从句表达的是与现在事实相反的事实，则常用虚拟语气，即用过去时态表示(如果涉及到be动词，一律都用were)。此时，主句则用过去将来时。
