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.。

eg: I feel very happy when you come to see me.When you are crossing the street,you must be careful.when引导的时间状语从句,when的从句可以用延续性动词,也可以用瞬间动词。
eg:He was working at the table when I went in. 。
Someone knocked at the door when I was sleeping.I will visit my good friend when I have time.注:when也可以作并列连词,表示一个动词正在进行的时候,突然间发生了另外一件事。
eg: I was fishing by the river,when someone called for help.We were working in the chemistry lab,when the lights went out.2. before 意为“在……之前”,引导时间状语从句时,表示主句的动作发生在从句的动作之前。
eg: We cleaned the classroom before we left school yesterday.He had been a cook before he went to college .after 意为“在……之后”,引导时间状语从句时,表示主句的动作发生在从句的动作之后。
eg: After you use plastic bags,you mustn't throw them about.He called me after he had finished his work.注:若主句和从句两个动作发生的先后顺序十分接近,那么也可以不用完成时态,如上面的第二句可改成:He called me after he finished his work.3. since引导的时间状语从句,译为“自从……”,主句常用现在完成时,从句常用一般过去时。
eg: I have taught English, since I came to Shenzhen.注:常用句型:It is +时间段+since从句译为:自从……有多长时间了。
eg. It is six years since she graduated from the university.4. until 意为“直到……时”,引导时间状语从句时,表示主句的动作发生在从句的动作之前。
当主句的谓语动词是持续性动词时,主句常用肯定形式;当主句的谓语动词是非持续性动词时,从句常用否定形式,not…until… 意为“直到……才……”,这时的until可以用before 来替换。
eg:I'll stay here until you come back.我会呆在这里,直到你回来。
(stay表示的动作可以持续)He didn't go to bed until he finished his homework.他直到做完作业才睡觉。
(go to bed 表示的动作不能持续)5. as soon as 意为“一……就……”,表示从句的动作一发生,主句的动作马上就发生。
eg:I'll tell him about it as soon as he comes back.6. while引导的时间状语从句,常译为“与……同时,在……期间”,while的从句中常用延续性动词或表示状态的词。
eg. They rushed in while we were discussing problems.Father was cleaning the car while I was playing computer games.注:while也可以作并列连词,表转折的关系,相当于but,译为“然而”。

(2)条件状语从句1.条件状语从句通常由if, unless引导。
eg:What shall we do if it snows tomorrow?Don’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。
(主将从现)eg:I’ll help you with your English if I 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。
eg:Hurry up, or you’ll be late.=If you don’t hurry up, you’ll be late.Study hard and you will pass the exam.=If you study hard, you will pass the exam.(3) 原因状语从句1.原因状语从句通常由because, since, as引导。
eg:He didn’t come to school beca use he was ill.As it is raining, we shall not go the zoo.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。
eg:------Why aren’t going there? ------Because I don’t want to.As he has no car, he can’t get there easily.3. because和so不能同用在一个句子里。
For 语气最弱,它所引导的分句必须放主句后面,引补充说明作用。
eg:Put on more clothes, for it's cold outside.注:because, since, as, for 的区别语气位置意义because 最强前或后“原因”;表客观因果关系;回答“”as 较强前“由于”;把众人所知的事实当作理由since 较弱前“既然”;就对方陈述的事实作为理由for 最弱后“理由”;对某一事实进行推断的理由(4)地点状语从句常用where(哪里)和wherever(无论哪里)eg. Where there is a will,there is a way. 有志者,事竟成。
We will go wherever the motherland need us most. 我们要到祖国最需要的地方去。
