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。

例如：He has so little time that he can’t go to the cinema with you.[Practice]( ) 1. This exercise is _____ difficult ______ . ( 山东济南)A. so; that few of us can doB. so; that few of us can do itC. too; for anyone of us to doD. too; for anyone of us to do it2. This math problem is so easy that I can work it out. (改为简单句) (广西柳州)This math problem is _____________________ to work out.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.( )2. Don’t just believe the advertisement. That kind of camera is ____ it s ays. (河北)A. as good asB. not as good asC. as well asD. not as well as7. 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.(2)although(though)不能用在同一个句子中。

例如：8. 地点状语从句地点状语从句常常由where来引导。
