初中英语状语从句知识点总结

初中英语状语从句知识点总结

初中英语状语从句知识点总结(一)用来修饰主句中的动词,形容词或副词等而充当状语的从句叫做状语从句.状语从句常用从属连词来引导,与主句连接起来.若置于句末,则前面不加逗号.根据意义和作用,状语从句可分为时间原因条件等几种.下面我们就来分析一下这几种状语从句.1时间状语从句时间状语从句常用从属连词when,after,until,as soon as,等来引导.当主句是祈使句或谓语动词是一般将来时态或情态动词时,其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态.这就是我们常说的“主将从现”.如:Please call me when you get there.当你到那时,请给我打个.I will write to you as soon as I arrive in Beijing.我一到北京就给你写信.<温馨提示>since引导时间状语从句表示“自从…以来”,从句中的动词一般表示动作的起点,用过去时;而主句的动作延续的情况则用一般现在时或现在完成时.常用的句型为:It has been/is+一段时间+since+过去时.如:I has been/is three years since we met last time.自从我们上次见面,已经三年了.2条件状语从句引导条件状语从句的连词或词组有:if(如果),unless(除非),as long as(只要)等.如果主句是将来时,条件状语从句也用一般现在时来表示.如:I will stay at home if it rains tomorrow.如果明天下雨,我就待在家.You can’t learn English well unless you work hard.除非你努力学习,否则是学不好英语的.<温馨提示>由if引导的条件状语从句,若从句表达的是与现在事实相反的事实,则常用虚拟语气,即用过去时态表示(如果涉及到be动词,一律都用were).此时,主句则用过去将来时.如:If I had enough money,I would buy it for you.如果我又足够的钱,我将把它买给你.I w ouldn’t do it if I were you.如果我是你,我是不会做的.3原因状语从句because,since,as,for都可用来引导原因状语从句,那么它们又有哪些区别呢①because用来表示“造成某种结果的直接原因”,语气较浓,常用来回答why提出的问句.如:---Why are you late---Because my bike is broken.②as和since用来表示“看的到的或是不说也知道的原因”,since也可译作:“既然”.如:As he is old enough,let him do it.他既然长大了,就让他干吧Since his shoes are worn out,let’s buy him a new pair.既然他的鞋坏了,那我们就给他买双新的吧.③for引导的原因状语从句不置于句首,常用来表示“顺便提及的理由”,只是稍带说明原因,并非强调.如:I must stay here,for it’s raining so hard.我必须得待在这儿,因为雨下的很大.初中英语状语从句知识点总结(二)1状语从句在复合句中,修饰主句中的动词、形容词或副词等的从句叫状语从句.状语从句根据它表达的意思可分为时间、地点、原因、目的、结果、让步、比较(或方式)和条件等类.1.时间状语从句引导连词有when,while,till,not…until,since,after ,before ,as soon asThe bus won’t start until everybody gets on.公共汽车直到每人都上车为止,才开动.When he knocked at the door I was cooking.当他敲门时,我正在煮饭.Last night before he came back home, his wife had already cooked dinner and waited for 2 hours.昨天晚上在他回到家之前,他的妻子已经做好晚饭足足等了他两小时之久.After I went to church, I went shopping.2. 地点状语从句地点状语从句通常由where, wherever 引导.Where there is a will, there is a way. 哪里有志向,哪里就有出路.有志者事竟成.Where there is a life, there is a hope. 哪里有生命,哪里就有希望.留得青山在,不怕没柴烧.Wherever you go, whatever you do, I will be right here waiting for you.不管你去哪里,不管你做什么,我都会在此守侯你.3.原因状语从句引导连词有because,as, since.He didn′t see the film because he had seen it.他没有看那部电影,因为他已经看过了.They couldn’t get on the train,for it was too crowed.比较:because, since, as和for1)because语势最强,用来说明人所不知的原因,回答why提出的问题.当原因是显而易见的或已为人们所知,就用as或 since.I didn't go, because I was afraid.Since /As the weather is so bad, we have to delay our journey.2)由because引导的从句如果放在句末,且前面有逗号,则可以用for来代替.但如果不是说明直接原因,而是多种情况加以推断,就只能用for.He is absent today, because / for he is ill.He must be ill, for he is absent today.注意because不能和so 连用.4. 目的状语从句引导连词有that, so that…,in order that.He must get up early so that he can catch the first bus.他必须早起,以便能赶上第一辆公共汽车.He repainted the house so that he could welcome the guests.Millions of trees are planted in North China so that the sand can be stopped from moving south.The mother left work earlier in order that she could be at home when the children arrived.So that …——以便/以致……例如:(1)They studied hard so that they could pass the exam.(2)They started early so that they caught the early bus.注意点:在例句(1)中,是引导目的状语;在例句(2)中,是引导结果状语.一般来讲,从句中含有情态动词的,为目的状语.无情态动词的,为结果状语.5.结果状语从句引导连词有that,so…that…,such….thatThe box is so heavy that I can’t lift it.这个盒子如此沉,以致我无法抬起来.such+名词性词组+that…So+形容词/副词+that…——如此……以致……例如:(1)She is such a good teacher that we all love her.(2)It was such a hot day that they didn’t go out for a walk as usual.注意点:+a+形容词+名词+that…,可以改写成:so+形容词+a+名词+that…,例句(1)可以改写成:She is so good a teacher that we all love her.2.在such+形容词+名词复数或不可数名词+that…结构中,形容词如果是many/few或much/little时,用so不用such,即:so+many/few+可数名词复数+that…,so+much/little+不可数名词+that…(1)There are so many people in the room that I can’t get in.(2)The man has so much money that he can buy a car.6.让步状语从句引导连词有though,although; even though/if; whatever; howeverAlthough he is young,he knows a lot of things.虽然他年龄小,但却认识许多事物.Even though you don’t like him, you still have to be polite.Whatever you say, I will not change my mind.注意although,though不能和but连用.7.比较(方式)状语从句以than为引导连词.常见连词(as)…as.., …than…; the…, the…Jim is older than Lucy(is).吉姆比路希年长.Skiing is more exciting than running.The more you practice, the more knowledge you will get.注意than 引导的比较状语从句中的谓语常省略.8.条件状语从句以if, unless为引导连词.If you eat bad food,you may be ill.如果你吃到坏了的食物,就会生病.If it doesn’t rain tomorrow, we will have a sports meet.注意主句是将来时,从句用一般现在时.状语从句中常见的误点1)时间状语从句和条件状语从句中的时态与主句的搭配:(俗称:主将从现)2)原因状语从句because与because of ;Because+从句和because of +n./ pron例如:I was late because I didn’t catch the bus.I was late because of the rain.。

初中英语语法---状语从句小结

初中英语语法---状语从句小结

初中英语语法—-—状语从句小结状语从句是一种作状语用的从句,修饰主句的动词、形容词、副词或修饰全句,补充说明时间、地点、原因、条件、方式、程度、状态等。

根据它表达的意思的不同,可分为时间状语从句、地点状语从句、原因状语从句、条件状语从句、比较状语从句、目的状语从句、结果状语从句等.时间状语从句、条件状语从句、结果状语从句、原因状语从句都是中考的重点。

一、时间状语从句时间状语从句表示主句动作发生的时间,引导时间状语从句的连词有when,as, while, before, after,as soon as,till,until,since等。

until 用于肯定句中,表示句子的动作一直持续到until短语所表示的时间为止,即表示动作的终点。

一般可译为“直到……时(为止)”或“在……以前”。

在这种用法中,句子的谓语动词必须是持续动词(非瞬间动词),如live,wait,last, love,like,stay, work, continue等。

until 用于否定句中,表示句子的动作直到until短语所表示的时间才开始发生,即表示动作的起点。

这可能要延续到星期五.用于否定句中:eg。

The secret was never told until after the old man’s death.这个秘密在老人去世后才说出来。

连词until以同样的方式分析作连词的until的用法。

作连词用的until的英文释义是up to the time when(直到……时为止)。

作连词的until用于肯定句中,表示主句的动作一直持续到从句动作发生或状态出现时为止。

一般可译为“……直到……为止”。

在这种用法中,主句的谓语动词必须是持续动词(非瞬间动词),如live, wait , last, love, like,stay, work, continue 等。

状语从句知识点详解(初中英语专项复习)16

状语从句知识点详解(初中英语专项复习)一个句子做整句话的状语,这个句子就叫做状语从句。

接下来我们重点复习几类状语从句。

一、时间状语从句定义和特征英语里如果用从句来表达一件事情或者一个动作发生的时间,那么这个从句就叫时间状语从句。

时间状语从句通常由when, while, as, before, after, since, as soon as, till/until等词引导。

【特征】含有时间状语从句的复合句,如果主句用一般将来时,从句用一般现在时表示将来。

(主将从现)—Daddy, when will we go out to fly a kite?—As soon as the rain _____.A. is stoppingB. stoppedC. will stopD. stops【答案】D【解析】句意:——爸爸,我们什么时候出去放风筝?——雨一停下(我们就去)。

as soon as 一……就……,引导时间状语从句,主句用一般将来时,从句用一般现在时。

故选D。

几种常见时间状语从句。

when引导:when表示“当……时候”。

既可表示在某一时间点发生的事,又可表示在某一时间段发生的事。

主句与从句描述的动作或事情可以是同时发生,也可以先后发生。

When I got home, I found my baby girl singing in the living room.当我到家时,我发现我的小女儿正在客厅里唱歌。

Things were different when I was a child.我小时候情况与现在不同。

【注意】when从句中的谓语动词可以是延续性动词,也可以是短暂性动词。

while引导:while表示“当……时候;在……期间”。

初中英语状语从句知识点总结状语从句是英语语法中的一个重要部分,它用来修饰或限定主句中的动作或状态。

以下是初中英语状语从句的知识点总结:1. 时间状语从句(Time clauses):用来表示动作发生的时间,常用的连词有when, while, before, after, until, as soon as等。

2. 地点状语从句(Place clauses):用来表示动作发生的地点,常用的连词有where, wherever等。

例如:I will go wherever you go.(无论你去哪儿我都会跟随。

)3. 原因状语从句(Cause clauses):用来表示动作发生的原因,常用的连词有because, since, as等。

4. 结果状语从句(Result clauses):用来表示动作的结果,常用的连词有so, such...that等。

初中英语知识点归纳:状语从句一时间状语从句1.时间状语从句表示时间,引导词有:when, while, as, till, until before, after, since等。

时间状语从句的引导词所表示的意思不尽相同,要注意把握不同引导词所表示的不同时间关系,以及它在具体句子中对应的时态、语态等问题。

注意:as(在……时候,因为),since(自从,因为),它们可以引导时间从句,并强调主句和从句的动作同事发生。

并且while有时还可以表示对比。

例如:(1)While my mother was reading the newspaper, I was watching TV.(read是延续性的动词,read和watch同事发生)I like playing football while you like playing basketball.我喜欢踢足球,而你喜欢打篮球。

(对比)(2)when(当……的时候),引导的从句的谓语动词可以是延续性动词,也可以是瞬间动词。

从句动作可与主语动作同事发生,也可在其后发生。

I was reading a book when she came into my room(come是瞬间动词,只能用when引导,不能用while)I often missed my home when(while) I lived in New York.(live是延续性动词,when可用while代替)(3)when和while的区别还在于: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 they were talking, the bell rang.正在他们谈话的时候,上课铃响了。

(4)as译作“一边……一边”、“随着……”,侧重主句和从句的动作同时发生。

有时可与when,while通用。

We always sing as we walk.我们总是边走边唱。

初中英语中考常考状语从句整理汇总(共9类)

中考英语常考状语从句1.时间状语从句When/while/as, since, as soon as, until/till, before, after,once, by the time, the minute/ the moment(一...就...), every/each time, whenever,...(1) When & while &as①When:表示“当...时”,后面跟时间点、时间段均可,因而从句的动词可以是非延续性动词(又叫短暂性动词)或延续性动词。

例如:He was watching TV when his mom came back.当他妈妈回来时,他正在看电视。

When his mom was cooking, he was watching TV.当他妈妈做饭的时候,他正在看电视。

②While:表示“当..时”,后面只能跟时间段,因而从句的动词也只能是延续性动词,且常为进行时态(现在进行时或过去进行时)。

例如:While his mom was cooking, he was watching TV.当他妈妈做饭的时候,他正在看电视。

③as:表示“一边...一边...”【注意】与while区分:当一个人同时进行两个动作时(即主从句的主语是同一个人时),只能用as。

还可表示“随着...”。

例如:Tom sings as he works. Tom一边唱歌一边工作。

As time went by, I learned how to be strong.随着时间的流逝,我学会了如何变得坚强。

(2) until & till (介词/连词)until:表示“直到...”,表示某个动作或状态一直持续到...为止。

例如:They waited until/till their mom came back.他们一直等到妈妈回来。

(主句谓语动词为延续性动词)“not...until”表示“直到...才”。

初中英语语法——状语从句

初中英语语法——状语从句

状语从句一、考点解读今天我们复习状语从句,英语中状语与中文的状语大致相同,分为时间状语、地点状语、原因状语、目的状语、结果状语、条件状语、方式状语等等。

如果一个主从复合句中的从句是用来表示时间,原因等等时,那就称为状语从句。

在主从复合句中修饰主句中的动词、形容词、副词等的从句叫做状语从句,又由于其功能与副词非常相近,又称做副词性从句。

状语从句一般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、比较状语从句和方式状语从句九种。

这节课我们主要复习如下的内容:1.时间状语从句2.地点状语从句3.原因状语从句4.目的状语从句5.结果状语从句6.条件状语从句7.让步状语从句8.比较状语从句9.方式状语从句二、专题梳理(一)时间状语从句在句子中起时间状语作用的句子称为时间状语从句。

时间状语从句可以放在句首、句中和句尾。

常用来引导时间状语从句的引导词有:when 当……时候while 当……时候as 当……时候、一边after 在……之后before 在……之前since 自从ever since 自从once 一……就……whenever 不管什么时候by the time 到……as long as 长达……as soon as 一……就……till/until 直到……1.when,while,as的用法从属连词when,while,as都可用来引导时间状语从句,意为“在……时候”。

但在具体用法上又不尽相同。

(1)这三个连词中,when用得最广,常可代替while与as。

与while相比,when引导的从句动词既可是延续性的,也可是终止性的。

as在这一点上与when相同,while所引导的从句中,动词只能是延续性的。

在初中阶段,我们几乎很少讲as引导时间状语从句。

是因为as在初中阶段是一种供了解性的内容。

e.g.When the fire broke out, all the studentswere sleeping soundly.(终止性的)当火灾发生时,所有的学生正在熟睡中。

初中英语状语从句知识点总结(一)用来润饰主句中的动词,形容词或副词等而充任状语的从句叫做状语从句。

状语从句常用隶属连词来引导,与主句连接起来。

若置于句末,则前面不加逗号。

依据含义和效果,状语从句可分为时刻原因条件等几种。

下面咱们就来剖析一下这几种状语从句。

1 时刻状语从句时刻状语从句常用隶属连词 when,after,until,as soon as, 等来引导。

当主句是祈使句或谓语动词是一般将来时态或神态动词时,其时刻状语从句中的谓语动词常用一般现在时态表明将来产生的动作或存在的状况。

这便是咱们常说的“主将从现”。

如:Please call me when you get there. 当你到那时,请给我打个电话。

I will write to you as soon as I arrive in Beijing. 我一到北京就给你写信。

<温馨提示>since 引导时刻状语从句表明“自从 , 以来”,从句中的动词一般表明动作的起点,用曩昔时 ; 而主句的动作连续的状况则用一般现在时或现在完结时。

常用的句型为:It has been/is+ 一段时间+since+ 过去时。

如:I has been/is three years since we met last time. 自从咱们前次碰头,现已三年了。

2 条件状语从句引导条件状语从句的连词或词组有:if( 如果),unless( 除非),as long as( 只要) 等。

如果主句是将来时,条件状语从句也用一般现在时来表示。

如:I will stay at home if it rains tomorrow. 假如明日下雨,我就待在家。

You can’t learn English well unless you wo rk hard.除非你努力学习,否则是学欠好英语的。

<温馨提示>由if 引导的条件状语从句,若从句表达的是与现在现实相反的事实,则常用虚拟语气,即用过去时态表示( 如果涉及到be 动词,一律都用were)。

此刻,主句则用曩昔将来时。

如:If I had enough money,I would buy it for you. 假如我又满足的钱,我将把它买给你。

I wouldn ’t do it if I were you. 假如我是你,我是不会做的。

3 原因状语从句because,since,as,for 都可用来引导原因状语从句,那么它们又有哪些区别呢?①because 用来表明“形成某种成果的直接原因”,口气较浓,常用来答复why提出的问句。

如:---Why are you late?---Because my bike is broken.②as 和 since 用来表明“看的到的或是不说也知道的原因”, since 也可译作:“已然”。

如:As he is old enough,let him do it. 他已然长大了,就让他干吧 !Since his sho es are worn out,let ’s buy him a new pair.已然他的鞋坏了,那咱们就给他买双新的吧。

③for 引导的原因状语从句不置于句首,常用来表明“趁便提及的理由”,仅仅稍带阐明原因,并非着重。

如:I must stay here,for it ’s raining so hard. 我有必要得待在这儿,由于雨下的很大。

初中英语状语从句知识点总结(二)1 状语从句在复合句中,润饰主句中的动词、形容词或副词等的从句叫状语从句。

状语从句依据它表达的意思可分为时刻、地址、原因、意图、成果、退让、比较(或方法)和条件等类。

1. 时刻状语从句引导连词有when,while ,till ,not,until ,since ,after ,before ,assoon asThe bus won’t start until everybody gets on.公共汽车直到每人都上车停止,才开动。

When he knocked at the door I was cooking.当他敲门时,我正在烧饭。

Last night before he cameback home, his wife had already cooked dinnerand waited for 2 hours.昨天晚上在他回到家之前,他的妻子现已做好晚饭足足等了他两小时之久。

After I went to church, I went shopping.2. 地址状语从句地址状语从句一般由 where, wherever 引导。

Where there is a will, there is a way. 哪里有志趣,哪里就有出路。

有志者事竟成。

Where there is a life, there is a hope. 哪里有生命,哪里就有期望。

留得青山在,不怕没柴烧。

Wherever you go, whatever you do, I will be right here waiting foryou.不论你去哪里,不论你做什么,我都会在此守侯你。

3. 原因状语从句引导连词有because,as, since 。

He didn ′t see the film because he had seen it.他没有看那部电影,由于他现已看过了。

They couldn ’t get on the train ,for it was too crowed.比较:because, since, as 和for1) because 语势最强,用来阐明人所不知的原因,答复 why提出的问题。

当原因是清楚明了的或已为人们所知,就用 as 或 since 。

I didn't go, because I was afraid.Since /As the weather is so bad, we have to delay our journey.2)由 because 引导的从句假如放在句末,且前面有逗号,则能够用 for来替代。

但假如不是阐明直接原因,而是多种状况加以揣度,就只能用 for 。

He is absent today, because / for he is ill.He must be ill, for he is absent today.留意because 不能和so 连用。

4. 意图状语从句引导连词有that ,so that, ,in order that 。

He must get up early so that he can catch the first bus.他有必要早上,以便能赶上第一辆公共汽车。

He repainted the house so that he could welcome the guests.Millions of trees are planted in North China so that the sand can bestopped from moving south.The mother left work earlier in order that she could be at home whenthe children arrived.So that , ——以便 / 致使,,例如:(1)They studied hard so that they could pass the exam.(2)They started early so that they caught the early bus.留意点:在例句(1) 中, 是引导目的状语;在例句(2) 中,是引导结果状语。

一般来讲,从句中含有神态动词的,为意图状语。

无神态动词的,为成果状语。

5. 成果状语从句引导连词有that ,so,that, ,such,.thatThe box is so heavy that I can ’t lift it.这个盒子如此沉,致使我无法抬起来。

such+名词性词组+that,So+形容词/ 副词+that, ——如此,, 以致,,例如:(1)She is such a good teacher that we all love her.(2)It was such a hot day that they didn ’t go out for a walk as usual.留意点:1.such+a+形容词+名词+that, ,可以改写成:so+形容词+a+名词+that, ,例句(1) 可以改写成:She is so good a teacher that we all love her.2. 在such+形容词+名词复数或不可数名词+that , 结构中,形容词如果是many/few 或much/little 时,用so 不用such,即:so+many/few+可数名词复数+that, ,so+much/little+ 不可数名词+that,(1)There are so many people in the room that I can ’t get in.(2)The man has so much money that he can buy a car.6. 退让状语从句引导连词有though,although; even though/if; whatever; howeverAlthough he is young ,he knows a lot of things.尽管他年纪小,但却知道许多事物。
