（一）状语从句归纳定义状语从句用作状语，是起副词作用的句子。
地址状语从句能够放在主句从前，也能够放在主句此后，时间、条件、原因和退步状语从句放在句首时需要用逗号和主句分开。
分类依照其作用能够分为时间、地址、原因、条件、目的、退步、方式和比较等状语从句。
作用它能够修饰谓语、非谓语动词、定语、状语和整个句子。
（二）状从句解1.状从句引用法when意“当⋯的候”。
When引从句的能够是延性，也能够是瞬。
并且when 有表示“就在那”while意“在⋯的候，在⋯ 的同”。
While 引从句的必是延性的，生，并主句和从句的作同生（也许相）。
While有能够表示比。
示例A liar is not believed when he speaks the truth.者真也没有人相信。
When he arrives , I’ll call you. When you laugh and smile, your body relaxes.While I was standing at the window, I saw several boys running along the street.While John was watching TV, his wife was cooking.as意“一⋯ 一⋯”。
As 引的作是延性的，生短，一般用于主句和从句作同生； as 也能够一前一后。
after意“在⋯此后”。
表示主句作生在从句作此后。
主句与从句的作关系与before 引的从句相反。
before意“在⋯从前”。
引的从句不用否定形式的，并且当 before 引的从句位于主句此后，有成“就，才”。
当主句用将来，从句是用在；若是 before 引的从句用的是去，主句多用去完成，以便体作的先后。
till意“直到”。
一般情况下能够和 until 互。
若是主句中的是瞬，必用否定形式；若是主句中的是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.With many hungry visitors waiting, don’stay too long at your table after you have finished.If an early exit is necessary, you can leave after a scene is over.You can ’ t watch TV before you finish your homework.Before it ended, the theatrewas almost empty.My father had left for Canada just before the letter arrived.She didn ’event know that it was an earthquake till she saw a shaking ( moving from side to side) light.The fireman worked very hard延性，用必定和否定形式都能够，但表达的意思不相同。

状语从句状语从句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（rain hard 下大雨）when got to school yesterday.While he was doing his homework, the telephone rang.As he walked along（沿着走）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（熄灭）.Let’s wait until the rain stops.We won’t start until Bob comes.Don’t get off（从下来）until the bus stops.【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。
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。
