初中英语语法专题 ： 状语从句 讲解与练习(PDF版)
状语从句
在英语中，状语从句在主从复合句中修饰主句中的动词、形容词或副词等。状语从句由从属连词引导，与主句连接，位于句首时，常用逗号分开，位于句末时，其前一般不用逗号。英语中的状语从句根据其用途可分为九大类，分别可表示时间、地点、原因、目的、结果、条件、让步、比较和方式。
学习状语从句关键是要掌握引导九类状语从句的有关连接词。只要记住连接词一般都能识别是何种状语从句，从而正确分析句子结构并理解句子意思。
一、时间状语从句
引导时间状语从句的连词较多，但它们的共同点是：
当主句是一般将来时或祈使句表示将来的意义时，时间状语从句用一般现在时(主将从现)。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.
时间连词when 的用法
一般来讲，when 的意思相当于at that time （在……时刻），从句的谓语动词通常是短暂动词，表示某一时刻的动作。不过，when 引导的从句也可接延续动词，这时从句往往用过去进行时态，表示某一时间段内发生的动作。时间从句所表达的时间通常是过去和将来。常见表示过去动作的四组时态搭配：
一、主句一般过去时＋从句一般过去时
I started my dinner when he left.
He left when I got there.
二、主句一般过去时＋从句过去完成时
I started my dinner when he had left.He left when I had got there.三、主句一般过去时＋从句过去进行时（三、四用法见过去进行时“长动作，短动作”）
The doorbell rang when I was telephoning.副词从句种类
常用连接词时间状语从句
when,while ,as,before ,after ,since ,till ,until ,as soon as 地点状语从句
where 原因状语从句
because ,as,for,since 目的状语从句
so that ,in order that 结果状语从句
so...that,so that,such...that 条件状语从句
If,unless 让步状语从句
although,though,even though,even if 比较状语从句
as,than 方式状语从句as,the way
四、主句过去进行时＋从句一般过去时
I was telephoning when the doorbell rang.
时间连词while的用法
while用作时间连词时，意思相当于during that time（在……期间），表示某一时间段内发生的动作。因此，从句的谓语动词通常接延续动词。
The doorbell rang while we were watching TV.Don’t talk while you’re eating.
注意：while还有对比的含义，解释为“然而”。eg:I prefer black tee,while he likes coffee.
时间连词as的用法
主、从句表示的两个同时进行的动作含有“一边……一边”的意思时，通常要用as。例如：
She sang as she went along.她边走边唱。
时间连词since的用法
since引导的时间状语从句，表示“自从……以来”，主句用一般现在时或现在完成时，从句用一般过去时。
常用结构为：“It has been…+since从句”或“It is…+since从句”。如：
It has been/is about ten years since I graduated from Nanjing University.
I have worked in this school since I graduated from Nanjing University.
时间连词until的用法
until的用法有以下特点：
第一、until既可以用作介词也可以作为连词，所以until的后面可以接名词短语也可以接时间从句。
第二、until前面的句子的谓语必须是延续性的，until后面接的从句的谓语须是短暂性动词或接时间点。
第三、until常用的句型结构有：
1．作为连词引导从句时的句型：主句的延续动词＋until＋从句的短暂动词；
2．作为介词接名词短语的句型：延续动词＋until＋时间点（不是时间段）。
I will be away from my office until next Tuesday.
注意：当主句或句子的谓语动词是延续动词时，通常用肯定形式。若主句或句子的谓语动词是短暂动词，则要用否定形式。因为否定之后表示的是一个状态，而状态则是延续的，这就是我们常说的not...
until（直到……才）的结构。例：
Wait until he comes back.We'll stay here until it stops raining.
He didn't leave the office until his boss came back.
表示“一……就”的结构
英文中，还有一些时间连词用来表达主句的动作和从句的动作相继发生，两者之间的时间间隔不长，相当于汉语里“一……就”的意思。此时，主句和从句的谓语都是短暂动词。初中阶段只需掌握as soon as。
We will leave as soon as it stops raining.It began to rain as soon as I arrived home.
二、地点状语从句
地点状语从句通常是由where引导，用来表达主句的动作发生的场所。其结构通常就是“where＋陈述句”，从句可以放在句首或句末。
Stay where you are.呆在原处别动Where there is a will,there is a way.有志者，事竟成。
三、原因状语从句
常用because,for,as和since这四个连词来引导原因状语从句。在这四个连词中，because的语气最强，只有它才能用来回答why的问句，所引出的原因往往是听话人所不知道的或最感兴趣的；也只有because才能被强调词如only,just和perhaps等来修饰。
My friends dislike me because I'm handsome and successful.
连词since表示人们已知的事实，是不需强调的原因，所以常译成“既然”，通常放在句首。例：Since we don't have class tomorrow,why not go out for a picnic?
连词as与since的用法差不多，所引出的理由在说话人看来已经很明显，或听话人熟悉而不需用because 加以强调。请看例句：
As Monday is a national holiday,all government offices will be closed.
注意：用介词表示因果关系常用的介词有：because of,due to和owing to。因为是介词，所以其后面不能接从句。We had an accident because of his carelessness.
四、目的状语从句
在英语中，常用的引导目的状语从句的连词有：so that,in order that和that。另外，在目的状语从句中常含有情态动词，比如may/might或can/could等。目的状语从句一般位于主句之后。但若要强调目的状语从句，可将so that或in order that引导的从句置于句首。
You must speak louder so that/in order that you can be heard by all.
In order that my roommate could study in peace and quiet,I turned off the TV.
We climbed high(so)that we might get a better view.
五、结果状语从句
常用的引导结果状语从句的连词有：so...that,so that和such...that。结果状语从句都要放在主句之后，而不能提到句首。
He is so young that he can not go to school.He is such a young boy that he can not go to school.
1．常用句型：so+形容词/副词+that从句so+形容词+a/an+单数可数名词+that从句
such+a/an+形容词+单数可数名词+that从句
such+形容词+复数可数名词/不可数名词+that从句
2．so和such的搭配规律
such修饰名词或名词词组，so修饰形容词或副词,so还可接many,few,much,little等。
六、条件状语从句
最常见的条件状语从句的引导词是if和unless。连词if表示“如果”，unless表示“如果不”或“除非”。
What shall we do if it snows tomorrow?Don’t leave the building unless I tell you to.
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.
注意：“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.
七、让步状语从句
常见的引导让步状语从句的词有though,although,even though和even if，此时，主句前不可用but，但可用yet或still。
Although he tried hard,(yet/still)he failed.尽管他努力了，但他还是失败了。
Although I didn't know anybody at the party,I had a very good time.
even if/though表示“即使”
He doesn’t want to marry her even if/though he loves her very much.
注意：还可以用介词来表示让步转折关系。主要有despite和in spite of等。介词只接名词（短语），不能接从句。
In spite of his inexperience,he did a very good job.
八、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。
连词as...as的用法
结构1：as＋形容词或副词＋as结构2：as＋形容词＋a(n)＋可数名词单数＋as
在否定句中第一个as可用so代替
This classroom is as big as that one.I can’t jump so/as high as he(does)
连词比较级+than…的用法
有than的比较句子里，主句中必须有比较级形式出现。Tom runs faster than John does.
注意：表示倍数比较的三种句型结构
1．“倍数＋比较级”结构：A is three times bigger（或其他形容词的比较级）than B
2．“倍数＋as...as”结构：A is three times as big（或其他形容词的原级）as B
3．“倍数＋名词”结构：A is three times the size（或其他形容词对应的名词形式）of B
九、方式状语从句
方式状语从句表示动作的方式，常见引导词有：as和the way。例：
When in Rome,do as the Romans do.Do it the way you were taught.

(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.

状语从句用法讲解和练习
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：
