原因状语从句

在复合句中,由从句表示的状语叫做状语从句。它可以用来修饰主语中的动词.形容词.副词等。根据它表达的意思,状语从句可以分为时间状语从句,地点状语从句,条件状语从句,比较状语从句,目的状语从句,结果状语从句和让步状语从句等。由连接词if或unless引导的状语从句叫做条件状语从句。在英文中,条件是指某一件事情实现之后(状语从句中的动作),其它事情(主句中的动作)才能发生,通常译作“假如”。(注意:在含有条件状语从句的复合句中,表示将来时态,主句是一般将来时态,从句要用一般现在时[主将从现原则]) [编辑本段] 条件状语从句的有关知识 语法引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如: If you ask him, he will help you.如果你请他帮忙,他会帮你的。 If you fail in the exam, you will let him down.如果你考试不及格,你会让他失望的。 另外,if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。如: If I were you, I would invite him to the party.如果我是你,我会邀请他参加聚会。 I would have arrived much earlier if I had not been caught in the traffic.如果没有堵车,我会到的早一点儿。 那么,除了if之外,是否还有其他连词也可以引导条件状语从句呢?回答是肯定的,不仅有,还有很多。这些词由于出现的频率较小,且用法较复杂一些,所以不如if为大家所熟知罢了。下面就这些词的用法以例句的形式进行一下简单总结。 1、unless conj.除非,若不,除非在……的时候 You will fail to arrive there in time unless you start earlier.如果你不早点动身,你就不能及时赶到那儿。 Unless it rains, the game will be played.除非下雨,比赛将照常进行。 2、on condition(that)...在……条件下,如果on condition (that)...引导的条件从句是主句事件发生的前提条件或唯一条件。 I can tell you the truth on condition that you promise to keep a secret.我可以告诉你真相,条件是你答应保守秘密。 You can go swimming on condition (that) you don't go too far from the river bank.你只有在不远离河岸的条件下才可以下水游泳。 3、supposing conj.如果,假如supposing引导的条件从句表示一种假设条件。 Supposing it rains, shall we continue the sports meeting?倘若下雨,我们的运动会还要继续举行吗?

语法讲解 时间状语从句的用法解析及练习

语法讲解时间状语从句的用法解析及练习 状语从句在复合句中作状语,其位置较灵活,可以在主句之前、之后或中间(放在句首时状语从句后面常用逗号,放在句末时状语从句前面往往不用逗号)。根据状语从句的含义,状语从句主要分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、方式状语从句、结果状语从句、条件状语从句、让步状语从句等八种。掌握以上各种状语从句的关键在于把握其相应的引导词。以下是对时间状语从句的基本用法进行小结,希望可以帮助到同学们有一更深的理解。 时间状语从句的引导词 when, before, after, as, while, till/until, since,whenever 时间状语从句的用法 时间状语从句的引导词所表示的意思不尽相同,要注意把握不同的时间状语从句的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对应时态、语态等问题。 1. when、as、while引导的时间状语从句分析: (1) when引导时间状语从句时表示“当……的时候”,when既可以指时间段也可指时间点,从句中既可用延续性动词又可用非延续性动词,且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。 注意体会如下例句:I’ll call you when I get there. 我一到那里就给你打电话。// When the wind blows, all the doors rattle. 只要风一吹,这门就吱嘎作响。// He stopped trying, when he might have succeeded next time. 他不再试了,其实他可能下一次就成功。// When I came home my wife was cooking dinner. 我回家时,妻子在做晚饭。 如果when引导的时间状语从句的主语与主句主语相同,而从句的谓语又是be动词时,那么从句中的主语和be可以省略;当when引导的时间状语从句的主语与主句主语相同时,往往还可以用“when+分词”的形式替代该状语从句。例如:When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。// When I came into the room (=When coming into the room), I found him lying there asleep. 当我进入房间的时候,我发现他躺在那儿睡着了。 (2) while引导时间状语从句时表示“当……的时候”,它强调主句的动作与从句的动作同时持续地进行,用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词,或者主句的动作发生在从句动作的进行过程中,主句中的谓语动词通常是非延续性动词,例如:Study while you study; play while you play. 该学习的时候就学习,该玩的时候就玩。// I met her while I was at school. 当我在学校的时候我遇见了她。 (3) as引导时间状语从句时表示“当……时,一边……一边……”,侧重表示两个动作同时发生(包括一个主语同时进行两个动作),或者一种动作随着另一种动作的变化而变化。例如:He jumps as he goes along. 他边走边跳。// I slipped on the ice as I ran home. 我跑回家时在冰上滑了一跤。// I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。// As the wind rose the noise increased. 刮风的时候噪声增大。

高考状语从句讲解

状语从句 一、时间状语从句 1、when, while, as 和whenever when 表时间点,时间段 while 表时间段;有“而”的意思 as “当……”,“一边……一边”,“随着……” whenever 每当,无论什么时候 It is cold when it snows. While there is life, there is hope. While we were speaking, he was reading newspaper. Just as Mrs Richards was entering the dinning-room, there was a knock on the front door. As we age, we trade strength for ingenuity, speed for thoroughness, and passion for reason. 随着年龄的增长,我们用力量换来了机敏,以速度换来了严谨,以热情换来了理智。 注:1)when还可作并列连词,其意义为“那时,这时”,相当于and at this/that time。常用于下列句式: sb.was doing sth.when...某人正在干某事就在这时…… sb.was about to/ going to do sth.when...某人正打算干某事就在这时…… sb.body has just done sth.when...某人刚干了某事就在这时…… 2)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 与as可互换使用。如: When/While/As I was walking down the street,I came across an old friend of mine. 2、before/ after It will be five years before we meet again.五年之后我们才能见面。 After you think it over, please let me know what you decide. After her husband had gone to work, she sent her children to school. 3、until, till, not...until 1)肯定句:主句的谓语是延续性动词,主从句均为肯定式,意为“某动作一直持续到某时间点才停止”

He smiled as he stood up. after 意为“在…之后”。表示主句 动作发生在从句动作之 后。主句与从句的动作时 间关系与before引导的从 句相反。With many hungry visitors waiting, don’t stay too long at your table after you have finished. If an early exit is necessary, you can leave after a scene is over. before 意为“在…之前”。引导的从 句不用否定形式的谓语, 并且当before引导的从句 位于主句之后,有时译成 “就,才”。当主句用将来时,You can’t watch TV before you finish your homework. Before it ended, the theatre was almost empty. My father had left for Canada

状语从句用法讲解和练习

第章状语从句 学习指导 状语从句在句子中作状语,用来修饰主句或主句的谓语。一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比 较和方式。尽管种类较多,但由于状语从句与汉语结构和用法相似,所 以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词。现分别列举如下: 状语从句分九类: 在这一章节的学习中,要求同学们掌握各类状语从句基本概念,并能够灵活应用。 第一节时间状语从句 时间状语从句用一般现在时表示将来。连接时间状语从句的连接词有:2.when,while,as均可表示“当……的时候”。 when强调“特定时间”,表示主句谓语动词的动作与从句谓语动词的动作是同时发生的,或从句的动作发生在主句的动作之前;while表 示的时间是一段,而不是一点,as多用在口语中,强调“同一时间”或“一前一后”,有时还有“随着”的含义。 When spring came, he felt like a trip.春天来了,他想去旅游。 As spring warms the good earth,all flowers begin to bloom.(as有“随着”的含义) as, when, while都表示主、从句的动作或状态同时发生,但三者也有

区别。as和when引导的从句既可表示一点时间,也可表示一段时间,从句中的谓语动词既可以是持续性动词,也可以为短暂性动词,经常可以互换使用;while引导的从句通常表示一段时间,从句中宜用持续性动词作谓语。当从句中的谓语动词为持续性动词时,这三者可以通用(前面例句中已有体现),再如: 1 / 18 Mother was worried because little Alice was ill, especially as / when / while father was away in France.妈妈担心,因为小艾丽思病了,特别是当父亲远在法国的时候。 如果从句和主句要表示一个人的两个动作交替进行或同时完成时,则多用as,可译为“一边......,一边......”。例如: He looked behind from to time as he went.他一边走,一边不时地往后看。 As time goes on, it's getting warmer and warmer..随着时间的推移,天气变得越来越暖了。 I thought of it just as you opened your mouth.你一张嘴我就知道你要 说什么。(若表示两个短促动作几乎同时发生时,用as的场合多于when.) 当主从句之间表示转折或对比关系时,多用while, 不用as或when。如:

状语从句讲解和练习

状语从句 状语从句修饰主句/主句的谓语。一般有九大类:表示时间、地点、原因、目的、结果、条件、让步、比较和方式等。 时间状语从句 1. 用when引导:when表示“当……时候”。如: Things were different when I was a child. 我小时候情况与现在不同。 People breathe more slowly when they are asleep. 人睡觉时呼吸比较缓慢。 2. 用while引导:while表示“当……时候”。如: We must strike while the iron is hot. 我们要趁热打铁。 I went swimming while the others played tennis. 我去游泳,其余的人都打网球去了。 注意:while 所引导的时间状语从句中谓语动词必须是持续性的,不能是短暂性的。 3. 用as引导:as表示“当……时候”“随着”。如: He dropped the glass as he stood up. 他站起来时,把杯子摔了。 We get wiser as we get old. 随着年岁的增长,我们也变得聪明些了。 4. 用before引导:before表示“在……之前”。如: Turn off the lights before you go to bed. 睡觉前要关灯。 Before he went to university he was a worker. 上大学之前他是工人。 5. 用after引导:after表示“在……之后”。如: I will tell you after they leave. 他们走我再告诉你。 After you finish the letter show it to me.信写完后给我看看。 6. 用until / till引导:until / till表示“直到……”。如: He waited until she was about to leave. 他等着一直到她准备离开。 I watched him until he disappeared in the distance. 我瞧着他直到他在远处消失。 这类句型的主句动词通常只能是延续性动词,不能是终止性动词。但是,在否定句中,主句动词可以是终止性动词,此时构成not…ntil [till]…句式,意为“直到……才……”。如:

第 二十五讲 状语从句的翻译

状语从句的翻译 状语从句内容丰富,涉及面广,可以用来表示时间、原因、条件、让步、目的、结果、等意义。英语状语从句的翻译,一般比较容易处理,通常可以直接翻译。但是这里我们所要讨论的是,在汉语译文中,要如何将状语从句置于恰当的位置,并如何将其与主句之间自然连贯地连接起来,如何按汉语的习惯表达将句子类型进行相应的变化。由于两种语言表达上的不同,在状语从句的安排方面,存在着明显的差异,所以在翻译的时候也需要根据汉语习惯来灵活翻译。 一、时间状语从句 在英语中,时间状语从句的连接词常常有:when(当...的时候),whenever(每当...),as(当...时),since(自从...),until(直到...,如果不....),till(直到...),before(在...前),after(在...后),assoonas(一...就),once(一旦...),themoment(一...就),immediately(一...就),theday(在...那天),nosooner... than(一...就),hardly(scarcely)... when(一...就),theinstant(一...就),instantly(一...就),directly (一...就),theminute(一...就),thesecond(一...就),everytime(每当...),bythetime (等到....的时候)等。翻译的时候,一般翻译在主句的前面。 (一)译成相应的时间状语 Whileshespoke, thetearswererunningdown. 她说话时,泪水直流。 Ashefinishedthespeech, theaudienceburstintoapplause. 他结束讲话的时候,听众掌声雷动。 (二)译成“一(刚、每)...就”的结构 Directlyheutteredthesewordstherewasadeadsilence. 他刚说出这些话,大家就沉默下来。 (三)译成条件句 由于时间状语的引导词除了显示时间关系之外,有时候可以表示条件关系, 所以还可以翻译为条件句。 Turnofftheswitchwhenanythinggoeswrongwiththemachine. 如果机器发生故障,就把电门关上。 Abodyatrestwillnotmovetillaforceisexertedonit. 若无外力的作用,静止的物体不会移动。

完整版原因结果目的状语从句讲解和练习答案

原因状语从句 (1) 原因状语从句通常由because, si nee, as,for 引导。 (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。此外,because和so不能同用在一个句子里。 例如:--- Why aren' t going there? ------- Because I don ' t want to. since弓I导原因状语从句,相当于now that,意思是因为....... ,既然.... ,鉴于...... ”。 例如:Si nee the rain has stopped , let ' s go for a walk.既然雨停了,我们出去散散步吧。 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。 例女口 : As he has no car, he can ' t get there easily. Since we have no money, we can ' t buy it. (4)for表示所说的理由是一种补充说明,for引导的从句一般不放在句子的开头。如: I decided to stop and have lun ch, for I was feeli ng quite hun gry. 小试牛刀:I was late for class yesterday there was someth ing wrong with my bike. He took off his coat he felt hot. (1) 结果状语从句由so…that, such …that, so that引导。 (2) so…that语such...that可以互换。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:…'“ +形容词(副词)+ that + 从句”。 例如:He was so glad that he couldn ' t say a word. Mother lives so far away that we hardly ever (几乎不,从来不) see her. 在由such…that引导的结果状语从句中,such是形容词,它修饰的可以是单数或复数可数名词,也可以是不 可数名词;其结构是:...'such +a / an + 形容词+名词+ that + 从句”。 例如:It was such a hot day that n obody wan ted to do anything. He had such long arms that he could almost touch the ceili ng. (天花板) 有时上述两种结构是可以互换的。 例如:It was such a won derful film that all of us wan ted to see it aga in. =The film was so won derful that all of us wan ted to see it aga in. ⑶如果名词前由many, much, little, few 等词修饰时,只能用so,不用such。 例如:Soon there were so many deer that they ate up all the wild roses. He has so little time that he can ' t go to the cinema with you. (4)如果主从句的主语相同,并且从句是否定的形式,可以用too...to...句型转化。 例如:He was so excited that he could n't go to sleep that ni ght. = He was too excited to go to sleep. (5)如果主从句的主语相同,但从句是肯定的形式,可以用adj.+ en ough替换。 例如:He is so old that he could go to school. = He is old en ough to go to school. 他够大了,可以去上学。
