中考英语总复习状语从句做题技巧

状语从句做题方法
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。

以下是状语从句做题的一些方法：
1. 确定主句和从句：首先要确定哪个句子是主句，哪个句子是从句。

一般来说，主句是句子的主要部分，表达主要意思，而从句则是为主句提供修饰或补充信息的句子。

2. 理解从句的类型：状语从句有很多种类型，包括时间、地点、原因、条件、目的、结果、让步、方式和比较等。

要根据上下文和句子的逻辑关系，确定从句的类型。

3. 注意连词的用法：状语从句通常由连词引导，不同的连词有不同的用法和含义。

要注意理解连词的含义和用法，以便正确理解句子的意思。

4. 注意语序：状语从句的语序通常是主从句颠倒的，即从句在前，主句在后。

但是，有些状语从句的语序可以不倒装，例如由“as soon as”、“no sooner...than”等引导的时间状语从句。

5. 注意语气：有些状语从句可以表示虚拟语气，例如“if only”引导的条件状语从句，表示与现在事实相反的假设。

总之，要做好状语从句的题目，需要理解句子的结构和逻辑关
系，注意连词的用法和含义，以及语序和语气等方面的问题。

同时，还需要多做练习，积累经验，提高自己的语言理解能力。

状语从句知识点详解（初中英语专项复习）状语从句的概念: 用一个句子作状语来修饰动词和形容词，以表明动作发生或状态存在的时间、地点、原因等，这个句子就叫做状语从句。

状语从句的分类：状语从句共分为九大类，包括：时间、地点、原因、条件、让步、目的、结果、方式、比较状语从句。

下面分别讲解：一、时间状语从句概念：用来表示时间的状语从句，由when, while, as, till, until，before, after, since等引导。

由于时间状语从句的引导词所表示的意思并非一致，不同引导词表达不同的时间，它们在句子中对应的时态、语态等也有所不同。

例如：when /while引导的时间状语从句when引导的从句的谓语动词通常是瞬间动词，也可以是延续性动词。

从句动作可与主语动作通常先后发生也可同时发生。

I was writing when my sister came back.( come是瞬间动词，只能用when引导，不能用while)He often wrote me when/while he studied in Shanghai International Studies University.( study 是延续性动词，while可代替when)While my mother was cooking , I was playing chess with dad. (cook是延续性的动词，cook和play同时发生)I like playing chess while my sister likes reading stories.我喜欢下棋，而我姐姐喜欢看小说。

(while表示对比)when和while的区别还有：while引导的时间状语从句多用于进行时态，而when引导的时间状语从句多用于一般时态。

While we were playing games, our headmaster called me .我们正在做游戏的时候，校长叫我了。

中考英语状语从句考点归纳与例析【重点讲解】中考英语试题对状语从句的考查主要涉及引导状语从句的从属连词的用法。

单项选择题的四个选项往往是四个连词，这是状语从句最常见的考查形式。

另一个考点是状语从句中的时态，因此，在学习状语从句时要弄清状语从句的几个主要类别，如时间、地点、原因、条件、让步、方式、目的、结果等，同时记住它们的“引导词”及其相关意义。

考点一：引导状语从句的连词的选择。

1、引导时间状语从句的连词主要有when, while, as, by the time, before, after, since, till/until, as soon as等。

其中when，while和as都可表示"当……时候"，但用法有区别:when意为"在……时;当……时",可表示"点时间"或"段时间",从句谓语可以是终止性动词,也可以是延续性动词。

例如:When I got home, he was having supper.as意为"边……边……"或"与……同时",重在表示两个动作同时发生。

伴随进行。

as从句是终止性动词时,主句通常也必须是终止性动词。

例如: They sang as they danced.while只可表示"段时间",从句谓语只限于延续性动词。

例如:While I was sleeping, my father came in.注意：从句谓语是持续性动词时,when，while和as可以互换。

主、从句谓语都是终止性动词时，when与as可互换。

从句谓语表示状态时，通常用while。

2、引导地点状语从句的常用连词是where。

例如：Where there is a will there ia a way.3、引导原因状语从句的连接词主要有because, as, since, for。

状语从句的复习重点及中考热点状语从句不仅是初中英语学习的重点，而且也是每年中考必考的内容之一。

从笔者研读历年全国各地中考英语试题对状语从句的考查内容来看，命题主要集中在引导状语从句的连词、状语从句的时态等方面；从九大状语从句来看，同学们应将复习重点放在时间状语从句、条件状语从句、结果状语从句和比较状语从句这四种上。

一、对时间状语从句的考查1．要点：1）引导时间状语从句的连词有：while，when，as，as soon as，until，not．．．until，before，after，since，etc．要掌握每个连词的含义及其用法，还有它们之间的一些区别。

2）when，while，as的区别：①三者均可表示“当……的时候”，如果主句表示的是短暂的动作，而从句表示的是一段时间，三者可通用。

如：I met Kang Li as／when／while I was walking along the street．当我沿街散步时碰见了康丽。

②as和when都可与终止性动词连用，while只能与延续性动词连用。

如：It was snowing when we got to the airport．当我们到达机场时，天正下着雪。

（不能用while）③as强调主句与从句表示的动作同时发生；while强调主句表示的动作持续于while所指的整个时间内；when可指主、从句所述动作同时或先后发生。

如：He sang as he went along．他边走边唱。

Please write while I read．我读的时候，请写下来。

When he reached home，he had a little rest．回到家后，他休息了一会儿。

3）until和till在肯定句中表示“直到……为止”，主句要用延续性动词；在否定句中，表示“直到……才”，主句常用终止性动词，这时till和until可用before替换。

英语时间状语从句讲解（一）when, while和as引导时间状语从句的用法一、when的用法如果只从现象来看，when从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。

1. When he was a child he was always trying out new ideas.3. Were you writing when the teacher came in?老师进来的时候，你在写信吗？4. Sorry, I was out when you called me.对不起，你打电话来的时候我出去了。

when从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，所以when多数情况下用的是一般过去时，则不用正在进行时。

因为如果用正在进行时，它表示的就是一段时间而不是一个时间点了。

根据这一点，有的文章补充说：when从句的动词大多是瞬时动词。

这种说法也可以参照。

实际上，when从句也可以有其它的时态，但几乎也不用进行时，因为它也只是作为一个时间参照点。

例如：2. When he had finished his homework, he took a short rest.3. Why do you want a new job when you have got such a good one already?二、while的用法相比于when来说，while从句的侧重点就不一样了。

while从句的侧重点在于描述动作正在发生的状态，它的意思是：当while事件正在发生的时候，另一件事如何如何。

所以，while从句一般用的是正在进行时。

而另一件事的状态没有硬性的要求，根据具体情况而定。

例如：1. While my wife was reading the newspaper, I was watching TV.2. While Jim was mending his bike, Lin Tao came to see him.3. While they were talking, the bell rang.正在他们谈话的时候，上课铃响了。

【网络构建】一、状语从句概述考向二状语从句的连接词概念：在复合句中作状语的从句叫作状语从句。

状语从句一般修饰主句中的动词、形容词或副词等。

功能：九大状语从句分别表示（时间、条件、原因、地点、目的、结果、方式、让步、比较）等意义。

位置：位置灵活，可用于主句之前或之后。

1．when, while, as引导的时间状语从句2. 比较until和till此两个连词意义相同。

肯定形式表示的意思是＂做某事直至某时＂，动词必须是延续性的。

否定形式表达的意思是＂直至某时才做某事＂。

动词为延续性或非延续性都可以。

正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。

肯定句：I slept until midnight. 我一直睡到半夜时醒了。

Wait till I call you. 等着我叫你。

（在肯定句中可用before代替。

例如：Let’s get in the wheat before the sun sets.）否定句：She didn’t arrive until 6 o’clock. 她直到6点才到。

状语从句知识点详解（初中英语专项复习）概念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。

结构：①主句+从属连词+从句Mum was cooking in the kitchen when I got home.②从属连词+从句+逗号（，）+主句When I got home, mum was cooking in the kitchen.状语从句分类时间状语从句条件状语从句常见句型转换题：If...not = unless,在句型转换题中，if （如果）常常和unless（除非）and（那么）或or（否则）互换。

If you don’t get up early, you will fail to catch the bus.(保持句意不变）= You won’t catch the bus unless you get up early.=You should get up early, or you will miss the bus.=Get up early, and you may/ will catch the bus.原因状语从句because 和so 不能用于同一句子中，because表示原因未知，语气最强回答why的提问。

because引导的从句可与because of引导的简单句互换。

as 语气最弱，常常用于口语中，since和nowthat（既然）表示已知的原因，一般放在主句之前。

She didn’t go to see the movie because the weather was bad.=She didn’t go to see the movie because of the bad weather.The sports meeting was put off because the weather was bad.=The sports meeting was put off because of the bad weather.目的状语从句so that +从句=in order that+从句常与in order to 和so as to +短语互换，目的状语从句常常会和情态动词can, may, will, could, might, would等连用He walked quickly so that he could get there on time.=He walked quickly in order that he could get there on time.=He walked quickly in order to get there on time.=He walked quickly so as to get there on time.结果状语从句So...that（如此.......以至于）在句型转换中常常会和enough to do 或者too...to互换，结果状语状语从句常常会和情态动词can, may, will, could, might, would等连用。

中考英语状语从句知识讲解状语从句即指在主从复合句用作状语的从句｡按照其意义,状语从句可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句等｡学习状语从句主要应注意引导状语从句的从属连词的用法与区别,以及从属连词在一定的语言环境中的意义与用法｡一、时间状语从句1.引导时间状语从句的从属连词很多,常见的有before, after, when, while, as, since, till, until, as soon as 等｡2.表示“当…时候”的 while, when, as 的用法区别是:while从句中的谓语动词必须是延续性动词;表示带有规律性的“每当”或当主、从句谓语动词的动作发生有先后时,只能用when;当表示“一边…一边…”或“随着”时,只能用as｡另外,用于此义的 as 所引导的时间状语从句谓语只能是动作动词,不能是状态动词｡如下面一道高考题的答案是B 而不能是A:“I’m going to the post office.” “_____ you’re there, can you get me some stamps?”A.AsB.WhileC.BecauseD.If3.until 在肯定句中通常只连用延续性动词,表示相应动作结束的时间;在否定句中通常连用非延续性动词,表示相应动作开始的时间,意为“直到…才”｡如:He waited until she was about to leave.他等着一直到她准备离开｡I did not begin to work till he had gone.他走了后我才开始工作｡4.表示“一…就”除用as soon as 外,还可用the minute, the second, the instant, immediately, directly, instantly, no sooner…than, hardly…when等｡如:I came immediately you called.你一来电话我就来了｡Hardly had she arrived when it began to snow.她刚到就下起雪来了｡The moment I have finished I'll give you a call.我一干完就给你打电话｡5.every time, each time, (the) next time, (the) last time, by the time, the first time, any time 等以time 结尾的词语也可用作连词,引导时间状语从句｡如: Next time you come in, please close the door.下次你进来,请关门｡He didn’t tell me anything the last time I saw him.上次我见到他时他什么也没告诉我｡By the time I got home, she had already gone to bed.我到家时她已睡觉了｡二、条件状语从句1.引导条件状语从句的从属连词主要有 if, unless, as [so] long as等｡如:Don’t come unless I telephone.除非我打电话,否则你别来｡If you watch carefully you will see how to do it.如果你仔细瞧你会看出该怎样做｡As long as you do your best, we’ll be happy.只要你尽力,我们就满意了｡2.in case 也可引导条件状语从句,其意为“如果”、“万一”｡如:In case I forget, please remind me about it.如果我忘了,请提醒我｡三、让步状语从句1.引导让步状语从句的从属连词主要有 although, though, however (=no matter how), even if(即使), whether…or(不论…还是)等连词｡如:The speech is good, though it could be better.这次演讲不错,虽然还可以再好一点｡He went out even though it was raining.尽管下雨,他还是出去了｡2.as 也可引导让步状语从句,但要将名词、形容词或副词等提到as 前,若提前的是单数可数名词,要省略 a / an｡如:Teacher as he is, he can’t know everything.虽然是老师,他也不可能什么都懂｡3.连词 while 有时也可表示“尽管”、“虽然”,引导让步状语从句｡如:Wh ile we don’t agree we continue to be friends.尽管我们意见不同,我们还是朋友｡4.whatever, whoever, however, whenever, wherever 等引导让步状语从句｡如:Don’t lose heart whatever you do.不管你做什么,都不要灰心｡Whoever you are, you can’t pass this way.不管你是谁,你都不能从这里通过｡注:表示“虽然”的though, although 不可与but 连用,但可与yet,still 连用｡四、原因状语从句1.引导原因状语从句的从属连词主要有because, as, since, seeing (that), now (that)等:They can’t have gone out because the light’s on.他们不可能出去了,因为灯还亮着｡Since you are going, I will go.既然你去,我也去｡Now that we are alone, we can speak freely.现在我们单独在一起,可以随便谈了｡2.除以上提到的大家比较熟悉的引导原因状语从句的从属连词外,when有时也可引导原因状语从句,其意“既然”｡如:I can’t tell you when you won't listen.既然你不想听,我就不告诉你了｡3.有关原因状语从句还应注意以下几点:(1) as 与since, now that 一样表示双方都知道的原因,通常位于主句前,且均不可用于强调结构被强调｡(2) 当表示直接的因果关系,回答why 时,或有only, just, all, partly, not, but 等副词修饰时,或用在强调结构中都只能用because｡(3) for 有时也可引出表示原因的分句,但它只能位于后面,对前一分句加以解释或推断｡(4) 不要受汉语意思影响将表示“因为”的连词与表示“所以”的so 连用｡五、地点状语从句引导地点状语从句的从属连词主要有where (在…的地方), wherever(无论什么地方), everywhere(每个…地方), anywhere(任何…地方)｡如:I’m not living where I was.我不在原处住了｡You can’t camp where [wherever, anywhere] you like these days.如今你可不能随便在哪儿宿营｡Everywhere I go, I find the same thing.不管我走到哪里,我都发现同样情况｡2.有的同学认为地点状语从句在平时见得不多,误认为考试不会涉及,但恰恰相反,地点状语从句却是英语考试经常考查的一个知识点｡请看以下考题:(1) When you read the book, you’d better make a ma rk _____ you have any questions.A.at whichB.at whereC.the place whereD.where(2) After the war, a new school building was put up _____ there had once beena theatre.A.thatB.whereC.whichD.when(3) You should make it a rule to leave things _____ you can find them again.A.whenB.whereC.thenD.there(4) She found her calculator ______ she lost it.A.whereB.whenC.in whichD.that以上四题均选where,其意为“在…的地方”,用以引导地点状语从句｡六、目的状语从句1.引导目的状语从句的从属连词主要有in order that, so that, in case, for fear 等｡如:I hired a boat so that I could go fishing.我租了一条船去钓鱼｡Take your coat in case it rains (should rain).带着雨衣以防下雨｡He studied hard in order that he could pass the exam.他努力学习,是为了能通过考试｡2.引导目的状语从句的so that 有时可省so 或that,即单独用so 或that 来引导目的状语从句｡如:Check carefully, so any mistake will be caught.仔细检查,以便任何错误都可检查出｡Bring it closer that I might see it better.拿近些,使我能看得清楚些｡七、结果状语从句引导结果状语从句的从属连词主要有so that, so…that, such…that等｡如:He was so angry that he couldn't speak.他气得话都说不出来｡He shut the window with such force that the glass broke.他关窗子用力很大,结果玻璃震破了｡注:so…that和such…that中的that有时(尤其在口语中)可省略｡八、比较状语从句引导比较状语从句的从属连词为as...as(和……一样),not as/so...as(和……不一样),than(比),the more...the more(越……越)｡这类从句常以省略形式出现｡如: The work is not so difficult as you imagine.这工作不像你想像的那么困难｡You look younger than you are.你看上去比你的实际年龄要年轻｡The more you study, the more knowledge you can get.你学的知识越多,你的知识越丰富｡He doesn’t work as hard as she (does).他工作不像她那样努力｡九、方式状语从句引导方式状语从句的从属连词有as(正如),as if或as though(好像)等｡如:Do as I told you.按我告诉你的那样做｡As a man lives, so he dies.正如人能活,也能死｡I remember the whole thing as if it happened yesterday.整个这件事我记得很清楚,就仿佛是昨天发生似的｡注:口语中like也可用连词引导方式状语从句｡如:Do it like he does.照他那样做｡She can’t cook like her mother does.她菜做得没有她妈那样好｡。
