状语从句讲解及练习初中英语状语从句讲解及专项练习状语从句指由句⼦来作状语。

它可以修饰谓语、⾮谓语动词、定语、状语或整个句⼦。

根据其作⽤可分为时间、地点、原因、条件、⽬的、结果、让步、⽅式和⽐较等从句。

状语从句⼀般由“主句+连词+从句”或者“连词+从句，主句”。

⼀、时间状语从句：由when，before，after，as soon as，since，until，not…until引导。

1. Mozart started writing music when he was four years old.当莫扎特4岁的时候，就开始写⾳乐作品。

2. He went home after he finished his homework yesterday.他昨天做完作业之后就回家了。

3. Mr. brown had worked in a bank for a year before he came here.布朗先⽣来这之前在⼀家银⾏⾥⼯作了⼀年。

语法专项2——状语从句【状语从句综述】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。

一、时间状语从句1.表示时间的状语从句可由when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner … than, hardly (scarcely) … when, every time等引导。

例如：When I came into the office, the teachers were having a meeting.当我进入办公室时，老师们正在开会。

He started as soon as he received the news. 他已得到这个消息，就出发了。

Once you see him, you will never forget him.一旦你见了他，你就不会忘记他。

No sooner had I gone to bed than I went to sleep.我一上床就睡着了。

2.when, while, as的区别这三个词都可以用作连接词，表示时间关系，但有所区别。

(1)when表示时间关系时，意思常常是“当(在)……的时候”。

主句和从句中的动作或事情可以同时发生，也可以先后发生。

例如：When we were at school, we went to the library every day.我们在求学的时候，每天都到图书馆去。

(2)while 用作连接词表示时间关系时，意思也是“当(在)……的时候”，主句中的动作或事情在从句中的动作或事情的进展过程中发生。

它有时可与when通用，但它只能指一段时间(a period of time)，而不能指一点时间的(a point of time)。

⾼考状语从句讲解和练习题定义——在复合句中由从句表⽰的状语称作状语从句，状语从句由从属连词引导，也可以由⼀个起连词作⽤的词组引导，有时甚⾄不需要连词⽽直接和主句连接起来。

类型——时间、地点、原因、结果、条件、⽬的、让步、⽅式、⽐较状语从句。

1.引导词when, while, as, as soon as, once, before, after, every time, each time, since, whenever, ever since, until ,till等。

2.whenever, each time, every time的⽤法。

注：whenever=no matter whenevery time / each time 每次，whenever 每当······时，表⽰习惯性、经常性的动作。

Whenever we met with difficulties, they came to help us.Each time he came to town he would visit our school.Eevery time I went to his house, he was out.注：whenever=no matter whenwhenever既可以引导时间从句也可引导名词性从句，no matter when只可以引导时间状语从句。

It does not matter whenever the party begins.3.before的汉英表达1）before的基本含义是“在·····以前”The train had left before he got to the station.注意：与before对应的是after引导的时间状语从句，表“在·····之后”。

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。

状语从句讲解及习题附答案（一）状语从句概述定义状语从句用作状语，是起副词作用的句子。

位置状语从句可以放在主句之前，也可以放在主句之后，时间、条件、原因和让步状语从句放在句首时需要用逗号和主句隔开。

分类根据其作用可以分为时间、地点、原因、条件、目的、让步、方式和比较等状语从句。

作用它可以修饰谓语、非谓语动词、定语、状语和整个句子。

（二）状语从句详解1. 时间状语从句引导词用法示例when 意为“当…的时候”。

When引导从句的谓语动词可以是延续性动词，也可以是瞬间动词。

并且when有时表示“就在那时”A liar is not believed when he speaks the truth.说谎者讲真话时也没有人相信。

When he arrives, I’ll call you. When you laugh and smile, your body relaxes.while 意为“在…的时候，在…的同时”。

While引导从句的谓语动词必须是延续性的，发生时间较长，并强调主句和从句的动作同时发生（或者相对应）。

While有时还可以表示对比。

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 意为“一边…一边…”。

As引导的动作是延续性的，发生时间较短，一般用于主句和从句动作同时发生；as也可以强调一前一后。

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.after 意为“在…之后”。

状语从句能力要求:了解状语从句的分类情况及各类状语从句中经常使用的连词；能够在真实的语境中断定从句与主句的逻辑关系，从而使用恰当的连词完成交际；能够辨别同类状语从句中近似连词的用法差异。

一、时间状语从句1. when, while 和as1) when 既可引导一个持续动作，也可引导一个短暂动作，可用于主句动作和从句动作同时发生或从句动作先于主句动作：When I lived there, I used to go to the seashore on Sundays.When the film ended, the people went back.当when 引出的时间状语从句为系表结构，而且其主语和主句的主语一致，其表语又是一个名词时，就可以那个以as引出的省略句，来代替when引导的从句：As a young man ( = when he was a young man ), he was fond of hunting.2) while 引导的动作必须是持续性的，侧重主句动作和从句动作相对比：Please don’t ta lk so loud while others are working.While I was wondering at this, our schoolmaster took his place.3) as 引导一个持续动作，多用于主句动作和从句动作同时发生：He hurried home, looking behind as he went.John sings as he works.4) when 还可用作并列连词，其意义为at this / that time, 常用于下列句式：be doing sth. when … / be about to do sth. when … / had ( just ) sth. when …此外，when 还可表示原因“既然”：It was foolish of you to take a taxi when you could easily walk there in five minutes.How can you hope for mercy yourself when you show none?5) while作为并列连词，意为“而，却”，表示对比：Mom was cooking in the kitchen while dad was watching TV in the sitting room.He likes pop music while I am fond of folk music.6) 如果主句表示的是短暂动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作时，when 、while和as可以互相换用：When / While / As I was walking down the street, I came across an old friend of mine.while必须与延续性动词连用；强调主句动作延续到从句所指的整个时间时，只能用while；表示“随着”只能用as；表示有规律的“每当”时或主从句动作有先后时，只能用when.The plane had left when we got to the airport. ( 不用while)As time passed, the event became more and more popular. (不用while或when )When winter comes, it becomes cold. ( 每当，不用as 或while )When you have finished your work, you may have a rest. ( 不用while 或as )2. as soon as, immediately, directly, the moment, the minute, the second, once ( 一旦…就…) no sooner … than…, hardly / scarcely … when …这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译为“一…就…”. 从句中用一般时态代替将来时态：The moment I heard the voice, I knew father was coming.The boy burst into tears immediately he saw his mother.Once you remember it, you will never forget it.No sooner had we arrived at the station than the train left.最后三个句式中，no sooner与hardly / scarcely 引导的主句谓语动词要用过去完成时，而than 与when的从句中要用一般过去时，此外，当把no sooner与hardly / scarcely提到句首时，应用倒装语序：I had hardly got home when it began to rain. = Hardly had I got home when it began to rain. On + v-ing ( hearing, seeing, returning等) 或n.( arrival, return等) 也等于as soon as.3. till, until 和not … until1) 肯定句：主句谓语动词必须是延续性动词，主句、从句都为肯定式，意为“某动作一直延续到某点时间才停止”：He remained there until / till she arrived.You may stay here until the rain stops.2) 否定句：主句谓语动词必须是非延续性动词，从句肯定式，意为“某动作知道某时间才开始”。

状语从句什么是状：句子中修、形容等的句子成分叫状，用来从地点、、原因、目的、果、条件、步、比、方式和陪同情况等方面修明。

e.g. He speaks English very well（.副作状）e.g. He is playing under the tree（.介短作状）e.g. I come specially to see you（.不定式作状）e.g. If I am not busy tomorrow,I will play football with you.（从句作状）e.g. Having had a quarrel with his wife,he left home in a bad temper（.分作状）状从句：状从句就是在复合句里起状作用的从句，能够表示、地点、原因、目的、果、步、比、方式、条件等。

引状从句的叫做隶属。

状从句的位置能够在句首，也能够在句末。

放在句首，从句后边常用逗号与主句分开；放在句末，从句前面常常不用逗号。

If it ’ s fine tomorrow, I wilgo with you.I will go with you if it’ s fine tomorrow.状从句分：1、状从句2、地点状从句3、原因状从句4、目的状从句5、果状从句6、条件状从句7、步状从句8、比状从句9、方式状从句状从句隶属：when, while, as, before, after, till/until, since, whenever, as soon as（一⋯⋯就）⋯⋯：主将从，主情从，主祈从一、 When/while/as （当⋯候）区：主句作与从句作生的（同/以前 /此后）；从句（延性 /瞬性）1）When:when 引状从句表示“当⋯⋯ 的候”，when既能够指段也可指点，从句中既可用延性又可用瞬性，且作既可和主句的作同生又可在主句的作以前或此后生。

且when 引的状从句中一般用一般在表将来（主将从）。

状语从句（Adverbial Clause）状语从句指句子用作状语时，起副词作用的句子。

它可以修饰谓语、非谓语动词、定语、状语或整个句子。

根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。

状语从句一般由连词(从属连词)引导，也可以由词组引起。

从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。

状语从句的种类状语从句可分为：1.时间状语从句；(adverbial clause of time)2.地点状语从句；(adverbial clause of place)3.原因状语从句；(adverbial clause of cause)4.条件状语从句；(adverbial clause of condition)5.目的状语从句；(adverbial clause of purpose)6.让步状语从句；(adverbial clause of concession)7.比较状语从句；(adverbial clause of comparison)8.方式状语从句；(adverbial clause of manner)9.结果状语从句。

(adverbial clause of result)[编辑本段]状语从句的时态特点一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。

例如：I will call you as soon as I arrive in Beijing. 我一到北京就给你打电话。

（这是由as soon as引导的时间状语从句，从句中的谓语动词arrive是一般现在时，表示一般将来时，决不可用will arrive）As soon as I have finished this work, I will go home. 我一完成此工作，就回家。

（从句中的谓语动词用现在完成时have finished，表示将来完成时,决不可用will have finished）If he comes back, please let me know.如果他回来了，请通知我。

中考英语复习——状语从句讲解及练习状语(1) 说明动作“何时”、“何地”、“如何”发生,或者说明形容词或副词的程度,一般由副词、介词短语、不定式、状语从句等充当。

）/ He woke up to find his house on fire.(他醒来发现房子着火了。

) / You cannot leave until your work is finished.(在你的工作被完成以前你不能离开)(2) 副词作状语位置较为灵活,；介词短语作状语,位置基本固定,；不定式作状语,一般表示目的、结果,；从句作状语(3) 多个状语相连时,一般先单词、后短语,先地点、后时间,先小概念、后大概念。

如：He went ouf of the room at a quarter to 23:00 last night and thendisappeared into the dark.(他昨夜22点3刻从房间里出来,然后消失在黑暗之中。

) /(4) 状语还可以用从句来充当,有时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、比较状语从句、让步状语从句、条件状语从句等。
