语法 状语从句讲解
语法状语从句
由从句担任的状语，在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子，它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。
第一讲时间, 地点状语从句
时间状语从句：when, while, as, before, after, since , whenever
until, till, by the time(注意时态)
as soon as, had hardly…when, had no sooner…than, (on doing sth…)
the moment, every time/ each time, the first time, once
e.g: When he came, I had cleaned the classroom.
He didn’t stop working until his mother came bake.
He worked until his mother came back.
As soon as he returned, he bought a new flat.
He had no sooner returned than he bought a new flat
He came to scene the moment he heard the news.
I thought her nice and honest the first time I met him.
Once he makes up your mind, he won’t change h is mind.
It was two years before I met him again. = Two years passed before I met him again.
注意点1. when引导的从句动词可以是延续性的或短暂性的，while引导的从句中动词必须是延续性的；while有时并不表示时间，而表示对比，表示“而”、“却”。
When I got home I found the door locked.
While(或When)we were working in the fields, it suddenly began to rain.
His pencil is red, while mine is yellow.
2. till与until not…until/till 解释为直到…才…主句动词一般是短暂性的
…till/until… 解释为直到…为止主句动词一般是延续性的一般情况下可以互换，但until可以位于句首，till则不能。
He worked until it was dark.
He didn’t stop working until it was dark.
Until it stops raining，the children can’t go out.
＝Not until the rain stops can the children go out.
地点状语从句
引导地点状语从句的连词是where 和wherever等。
I ll go wherever the people want me to go.(wherever＝to any place where)
He works where his grandfather fought.(where＝in the place where)
You must stay where you are. = You must stay in the place where you are.
Wherever you go, I go too.
Where there is water, there is life.(那儿有… 那儿就有… Where there is a will, there is a way.)
圈出其中的从句并翻译:
1.Whenever it is his turn to speak, he gets nervous.
2.Every time he comes, he always tells us something interesting.
3.When I get the news, I will let you know as soon as possible.
4.Once he makes a promise, he will never break it.

9.The hunter made mark on the tree where he stops.
10.Wherever he is, he will find time to do some reading.
第二讲原因、目的、结果状语从句
原因状语从句
原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as , now that（既然）等，for 表示因果关系时（它引导的不是从句）为并列连词，语气不如because强, considering that, seeing that(既然,由于) not that…but that…(不是因为…而是因为…)
e.g. He is disappointed because he didn't get the position.
Since everybody is here, let’s begin.
It must have rained last night, for the ground is still wet.
Seeing that the weather is bad, we’ll stay at home.
注意点: 1. 回答以why提出的问题时，只能用because,而不能用as等。
2. since＝now(that),表“既然”意，表示已知的或明显的原因，由此加以推论。
Now that/Since you are free today, you may have a rest at home or go out for a walk.
3. for 是一个并列连词，用来连接两个并列句，引导的句子是对前面一句话的内容的推测
或补充说明。(一般有逗号逗开)
The day has broken, for the birds are singing.
4. 区别几个介词短语：because of , due to, owing to, on account of
目的状语从句
引导词有so that, in order that, that, in case（免得，以防）, for fear that。目的状语从句谓语常含有can/could/may/might/will/would等情态动词。
e.g: He said aloud so that everybody could hear him.
I left the room quietly for fear that I might wake him up.
Speak clearly, so that they may understand you.
He left early in case he should miss the train.
结果状语从句
结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that （从句谓语一般没有情态动词）, so … that, such … that等引导。
1.He works so hard that he makes great progress in his studies.
2.It s such a difficult problem that nobody can work it out.
3.There s not any noise here so that I feel very comfortable.
c.f. I got up early, so that I caught the bus.

9.I wrote as clearly as possible so that I might get high marks.
10.I wrote as clearly as possible, so that I got high marks.
第三讲条件、方式、比较、让步状语从句
条件状语从句
条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句。引导条件状语从句的词（组）主要有if, unless, in case, so/as long as, on condition that, provided that, supposing that 等
e.g. If he is not in the office, he must be out for lunch.
So far as I know（据我所知）, he will be away for three months.
You can go swimming on condition that ( = if ) you don’t go too far away from the river bank.
In case he comes, let me know.
As long as you don’t lose heart, you will succeed.
Unless you work hard, you won’t pass the exam.
If you doesn’t work hard, you won’t pass the exam
注意：1. 条件从句中的if 不能用whether替换。
2. 祈使句+and you will do的结构中也隐含了一个状语从句
Use your head and you will find a better way out.
If you your head, you will find a better way out
3、在时间和条件（有时也在方式、让步等）从句中，主句是一般将来时，从句通常用一般现
在时表示将来。
e.g. We’ll go outing if it doesn’t rain tomorrow.
I’ll write to you as soon as I get to Shanghai.
让步状语从句
让步状语从句表示在从句的情况下,主句的情况仍然出现
though, although, even if, even though, as, while, whether…or, no matter+wh.. wh+ever
eg: Though he is a child, he knows a lot.
Whether it rains or not, I shall go out for an outing tomorrow.
Whatever ( = No matter what ) you say, I’ll never change my mind.
However hard I try, I can’t finish the work i n time.
注意力1. as 作“尽管”意时，一般将其句中的表语放在句首，用倒装扮：
Although he is young, he knows a lot. =
Young as he is, he knows a lot.
若表语为名词，冠词要省略：
Although he is a child, he has remembered a lot of English words.
Child as/though he is, he has remembered a lot of English words.
2. although或though不能与but同时出现在一个复合句中，
但是“Although/Though…，(and)yet…”句式却是正确的。
Although it is raining heavily, yet they are repairing the bridge.
3. while引导的从句位于句首, 相当于although
While we don’t agree on the matter, we continue to be friends.
4. in spit of, despite 后面跟的是名词短语
In spite of the heavy rain, they still worked in the fields.
方式（或比较）状语从句
引导词有as, as if, as though, than, as/so…as,the more…the more.例如：
Tom is not so/as tall as John.
注：as…as既可用于肯定句，又可用于否定句，so…as只能用于否定句。
You must do the exercise as I show you.
He acted as if nothing had happened.
I have made a lot more mistakes than you have.
He smokes cigarettes as expensive as he can afford.
The busier he is, the happier he feels.
圈出其中的从句并翻译
1.The road will be blocked if there is another snow.
2.We won’t let you in unless you show us your pass.
3.You may use my bike as long as you return it before Friday.
4.Although he lacks experience, (yet) he is ready to do the job.

语法状语从句 由从句担任的状语,在句子中可修饰谓语(或其它动词)、形容词、副词或就是整个句子,它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。 第一讲时间, 地点状语从句 时间状语从句:when, while, as, before, after, since , whenever until, till, by the time(注意时态) as soon as, had hardly…when, had no sooner…than,(on doing sth…) the moment, every time/ each time, the first time, once e、g: When he came, I had cleaned the classroom、 He didn’t stop working until his mother came bake、 He worked until his mother came back、 As soon as he returned, he bought a new flat、 He had no sooner returned than he bought a new flat He came to scene the moment he heard the news、 I thought her nice and honest the first time I met him、 Once he makes up your mind, he won’t change his mind、 It was two years before I met him again、= Two years passed before I met him again、注意点1、when引导的从句动词可以就是延续性的或短暂性的,while引导的从句中动词必须就是延续性的; while有时并不表示时间,而表示对比,表示“而”、“却”。 When I got home I found the door locked、 While(或When)we were working in the fields, it suddenly began to rain、 His pencil is red, while mine is yellow、 2、till与until not…until/till 解释为直到…才…主句动词一般就是短暂性的 …till/until… 解释为直到…为止主句动词一般就是延续性的一般情况下可以互换,但until可以位于句首,till则不能。 He worked until it was dark、 He didn’t stop working until it was dark、 Until it stops raining,the children can’t go out、 ＝Not until the rain stops can the children go out、 地点状语从句 引导地点状语从句的连词就是where 与wherever等。 I ll go wherever the people want me to go、(wherever＝to any place where) He works where his grandfather fought、(where＝in the place where) You must stay where you are、= You must stay in the place where you are、 Wherever you go, I go too、 Where there is water, there is life、(那儿有… 那儿就有… Where there is a will, there is a way、) 圈出其中的从句并翻译: 1.Whenever it is his turn to speak, he gets nervous、 2.Every time he comes, he always tells us something interesting、 3.When I get the news, I will let you know as soon as possible、 4.Once he makes a promise, he will never break it、 5.I had no sooner run into the school gate than I heard the bell for class、 6.I found the lost watch under a desk after the children had left for home、 7.He had to be called two or three times before he came down to dinner、 8.We didn’t notice anything wrong with the washer until we started using it、 9.The hunter made mark on the tree where he stops、 10.Wherever he is, he will find time to do some reading、
语法讲解 时间状语从句的用法解析及练习
语法讲解时间状语从句的用法解析及练习 状语从句在复合句中作状语，其位置较灵活，可以在主句之前、之后或中间(放在句首时状语从句后面常用逗号，放在句末时状语从句前面往往不用逗号)。根据状语从句的含义，状语从句主要分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、方式状语从句、结果状语从句、条件状语从句、让步状语从句等八种。掌握以上各种状语从句的关键在于把握其相应的引导词。以下是对时间状语从句的基本用法进行小结，希望可以帮助到同学们有一更深的理解。 时间状语从句的引导词 when, before, after, as, while, till/until, since，whenever 时间状语从句的用法 时间状语从句的引导词所表示的意思不尽相同，要注意把握不同的时间状语从句的引导词所表示的不同时间关系，以及它在具体句子中对应的对应时态、语态等问题。 1. when、as、while引导的时间状语从句分析： (1) when引导时间状语从句时表示“当……的时候”，when既可以指时间段也可指时间点，从句中既可用延续性动词又可用非延续性动词，且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。 注意体会如下例句：I’ll call you when I get there. 我一到那里就给你打电话。// When the wind blows, all the doors rattle. 只要风一吹，这门就吱嘎作响。// He stopped trying, when he might have succeeded next time. 他不再试了，其实他可能下一次就成功。// When I came home my wife was cooking dinner. 我回家时，妻子在做晚饭。 如果when引导的时间状语从句的主语与主句主语相同，而从句的谓语又是be动词时，那么从句中的主语和be可以省略;当when引导的时间状语从句的主语与主句主语相同时，往往还可以用“when+分词”的形式替代该状语从句。例如：When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。// When I came into the room (=When coming into the room), I found him lying there asleep. 当我进入房间的时候，我发现他躺在那儿睡着了。 (2) while引导时间状语从句时表示“当……的时候”，它强调主句的动作与从句的动作同时持续地进行，用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词，或者主句的动作发生在从句动作的进行过程中，主句中的谓语动词通常是非延续性动词，例如：Study while you study; play while you play. 该学习的时候就学习，该玩的时候就玩。// I met her while I was at school. 当我在学校的时候我遇见了她。 (3) as引导时间状语从句时表示“当……时，一边……一边……”，侧重表示两个动作同时发生(包括一个主语同时进行两个动作)，或者一种动作随着另一种动作的变化而变化。例如：He jumps as he goes along. 他边走边跳。// I slipped on the ice as I ran home. 我跑回家时在冰上滑了一跤。// I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。// As the wind rose the noise increased. 刮风的时候噪声增大。

英语语法从句讲解
从句 从句按其在主句中的句法功能可分为三类: 即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。 引导从句的词称作关联句. 一、名词性从句 引导这些名词性从句的关联词包括: 从属连词that, if, whether; 连接代词 who,whoever,whom,whomever,which,whichever,what,whatever,wh ose; 连接副词where, when, why, how。 其中, 从属连词只起连接作用, 在从句中不充当任何句法成分, 而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分. That Owen should have married his cousin is not at all surprising. The fact is that he didn't go to the dinner party. I don't know if he will attend the meeting. Have you heard the news that Mary is going to marry Tom? 你听说玛丽要和汤姆结婚的消息了吗?(that引导同位语从句) [提示]
1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. It's well-known that water is indispensable to life.(形式主语) 2. 为保持句子平衡, that引导的宾语从句也常用it代替, 而将真正的宾语从句置于主句句末。这常常出现在主句有形容词或分词作宾语补足语的情况下。 He made it quite clear that he preferred to live here. 3. 从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语 从句。whether可与or(not)连用, 而if不可以。 I don't know whether (if) she is at home. Whether she comes or not makes no difference. 4. that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。that可省略, what则不可省。 He always means what he says. She suggested (that) he do it at once. 5. 同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。同位语从句一般用来解释说明这些名词的具体含义和内容。 We are familiar with the idea that all matter consists of atoms. The news that we are invited to the conference is very encouraging.

(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.

英语语法之时间状语从句
时间状语从句常由以下连接词引导：when（当……时），as（一边……一边；当…时），while（在……期间），after（在……之后），before（在……之前），as soon as（一……就），since（自从），till(until)（直到……，直到……才），whenever（任何时候），the moment（一……就），no sooner than（一……就），hardly…when… （一……就）等。由以上连接词（或词组）连接的主从复合句中，主句和从句的动作，有的是同时发生，有的是先后发生。因此，要特别注意根据连接词所代表的时间不同，主句和从句的谓语要使用相应的时态。这是掌握时间状语从句的关键。 1. when 和whenever 引导的从句：从句的动作和主句的动作可以同时发生，也可以先于主句的动作发生。例如： When we reached home, it was already dark. 我们到家的时候天已经黑了。 When my cousin came yesterday, I was playing volleyball. 昨天我表哥来时，我正在打排球。 When it rains, I go to school by bus.下雨的时候，我坐车去学校。 I shall tell her the good news when she comes. 她来时，我将告诉她这个好消息。（主从句都表示将来发生的动作，但要注意从句中要用一般现在时，表示将来。） Come to see us whenever you can.你什么时候有空，就过来看看我们。 2. while 和as 引导的从句：while表示“当…过程中”，强调某一段时间主句和从句的动作在同时发生。as表示“当…时”或 “一边…一边”，主句和从句的动作同时发生。例如： Work while you work; play while you play. 该工作的时候就工作，该玩的时候就玩。 While he is reading, he always makes notes. 他经常一面看书，一面做笔记。 She sings as she goes along.她边走边唱。 You will grow wiser as you grow older. 随着年龄的增长，你会更加聪明起来。 3. before 和after 引导的从句：前者一般表示主句的动作发生在从句动作之前。后者表示主句的动作发生在从句动作之后。 例如： I didn’t know any English before I came here. 我来这儿之前，一点英语都不懂。 I had written my report before my mother came back.
