完整版初中状语从句讲解及习题附答案
（一）状语从句概括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（或许相）。
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”。
引的从句不用否认形式的，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，主句多用去达成，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，必用否认形式；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，用必定和否认形式都能够，但表达的意思不一样样。

初中状语从句全面讲解练习题及答案1、基本含义状语修饰动词、形容词、副词或整个句子。
通常由副词、介词短语、动词不定式、分词和从句等担当。
请用下划线划出下列句子中的状语，并说明是什么在做状语：He speaks English very well.He is playing under the tree.I come specially to see you.The boy was praised for his bravery.When she was 12 years old, she began to live in Dalian.If I am not busy tomorrow, I will play football with you.什么是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。
例句：I will call you as soon as I arrive in Beijing.If he comes back, please let me know.I know how to light a camp fire because I had done it before.2、用法归纳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 we 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.[Practice]I didn’t know he came back ____ I met him in the street. (2007 河北) A. since B. When C. until D. after请填入适当的引导词I haven’t heard from him _____ he went to America .We found the books two days ____ he had gone away .Do not leave the room _____ you have finished the test.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 tomorrowDon’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.He won’t be late unless he is ill.(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.[Practice]1. If you ____ late tomorrow morning, you won’t catch the early bus. (2007福建厦门)A. get upB. don’t get upC. will get up请完成下面句子的翻译：如果明天有空,我会和你一起去喂狗._______________________如果明天他不来,我会代替他去的._________________________2、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.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.(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.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..(3)如果名词前由many, much, little, few等词修饰时，只能用so, 不用such。
