4. 从句作原因状语

引导原因状语从句的从属连词有because (因为),as (由于),since (既然),now(that)(既然),when (既然),seeing (that)(由于,鉴于),considering (that)

(考虑到),given (that)(考虑到)for (为)等

(1)because引导的原因状语从句一般放于主句的后面,because从句位于句首时要用逗号分开,放在句末时,可不用逗号分开。because表示直接原因,语气最强,最适合回答why引导的疑问句。

例如:

I do it because I like it.

我做这件事是因为我喜欢。

You can trust those p roducts because the quality n ever varies.

你可以信赖那些产品,因为它们的质量从来不变。

We went by bus because it was chea per.

我们乘公交汽车去,因为这样便宜一些。

注意:“not ... because结构中的not否定的是because引导的整个从句,

例如:

误:The country is not strong because it is large.

正: The country is strong not just because it is large.

国强不在大。

I did n't help him,not because I was un willi ng,but because I was un able to do it. 我

没有帮助他,不是因为我不愿意,而是因为我力不从心。

2. since 引导的原因状语从句一般放于主句之前表示已知的、 显然的理由 ( 通常被 翻译成“既然” ),较为正式,语气比 because 弱。

例如:

Since you are free today, you had better help me with my mathematics. 既然今天你

休息,你最好帮我补习数学。

Since you don't trust him,you should not employ him. 你既然不信任他,你就不该雇用

他。

注意: seeing (that) , now (that) , considering (that) , in that 这几个词汇与 since 引导的原因状语从句意思相近,都表示“既然” 。

例如:

Seeing (that) he refused to help us, there him.

他既然曾经拒绝帮助我们,我们没有理由要来帮助他。 Now (that) you are grown up, you should not rely on your parents. 既然你长大了,就

不应该依靠你的父母了。

Considering (that) everybody is here, let 既然大家都到

了,我们就开始讨论吧。 In that he is ill, he feels unable to do it. 因为他生病了,他觉得做不了那件事。

3. as 引导原因状语从句时表示附带说明的“双方已知的原因”,语气比since 弱, 较为正式,位置较为灵活 (常放于主句之前 )。

例如:

As it is raining, you 既然在下

雨,你最好乘出租汽车。 As you are tired, you had better rest. 既然累了,你最好休息一下。

I went to bed early, as I was exhausted. 我睡得早,因为我已筋疲力尽了。's no reason that we should now help

's begin our discussion.

d better tak

e a taxi.

4. for 引导的是并列句表示原因但并不说明主句行为发生的直接原因,只提供一些辅助性的补充说明,for 引导的并列句只能放于主句之后并且必须用逗号将其与主句隔开。

例如:

He could not have seen me, for I was not there. 他不可能见过我,因为我不在那里。He seldom goes out now,for he is very old.

他难得出门了,因为他年事已高。I do it because I like it. 因为我喜欢,我就做了。

Since no one is against it, let ' s make a decision. 既然没有人反对,那我们就这样定下来。

初中英语时间状语从句讲解及练习

语法 29时间状语从句 一、什么是状语从句 状语就是在一句话中表示该句子的时间、地点、方式、原因、条件等成分。状语从句就是用一个从 句表示状语。状语从句根据它表达的意思不同,可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。 与状语一样,状语从句的位置比较灵活。既可置于主句之前(通常用逗号与主句隔开),也课置于主句之后(不需要用逗号与主句隔开),有时甚至可以置于主句之中。 二、时间状语从句 1. 主句和从句同时发生,这类从句由从属连词when, while, as引导。 He was hungry when he came home. I was crying while everyone was laughing. As I walked out, he walked in. as, when, while, 的区别 ① as强调从句的动作与主句动作同时发生及持续,具有at the same time的意思 他继续往下谈的时候,越来越兴奋。 as还可以表示一边??一边??,强调从句和主句中两个动作交替进行或同步进行。 他们边走边聊。 as还有“ 随着”的含义 随着春天的到来,天气暖和起来。 ② when 强调动作点的特定时间,具有at the time that 的意思 当老师走进来的时候,我们都站起来了。 ③ while 表示较长的期间,具有during the time that 的意思 当我在这的时候,我很安全。 2.主句发生在从句之前,这类从句由从属连词before, until 引导 ,before 意为“ 在---之前” until 在肯定句中意为“直到 --- 为止”,在否定句中意为“直到 --- 才”。从句既可置于主句前,也可置 于主句之后。 回家之前我必须干完所有的活。

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。

状语的具体讲解(九)伴随状语

导读:伴随状语是指状语的动作伴随主句发生 1. 分词做伴随(区分了现在分词和过去分词) 2. with符合结构做伴随(列出with不同结构的特征) 3. 独立结构做伴随(介绍了独立结构的构成) 4. 形容词做伴随表状态 5. 名词做伴随表身份 伴随状语是由一个主语发出两个动作或同一个主语处于两种状态,或同一个主语 发出一个动作时又伴随有某一种状态。 做伴随状语的成分 1. 分词做伴随 分词做伴随的时候,表示主语在同一时间的两种状态或两个动作 分词做伴随状语分为现在分词和过去分词, 现在分词(动词的ing结构)表示主语发出了这个动作,比如: The dog en tered the room, following_his_master. 这条狗跟着主人进了屋。(主语是狗,发出跟着主人的动作) 过去分词(done)表示主语承受了这个动作 The master en tered the room, followed_by_his_dog. 主人进了屋,后面跟着他的狗。(主语是人,被狗狗跟着) 2. with复合结构做伴随状语 with做伴随的时候,表示主语动作发生或出于某种状态时,身边环境的状态。 (1)with+名词/代词+介词短语” The man was walking on the street,with a book under his arm.(那人在街上走着 , 腋下夹着一本书.) (2)with+名词/代词+形容词”

With the weather so close and stuffy,ten to one it 'lrain presently.天气这么闷热, 十之八九要下雨.

时间状语从句讲解和练习

时间状语从句 用句子表达一件事情或一个行为发生的时间,这个句子就叫时间状语从句。时间状语从句根据其所表示的时间不同,所使用的连词也不同。下面我们一起来看一下几个常见的时间状语从句: 1.when引导的从句:表示主句的动作和从句的动作同时发生,或从句的动作发生在主句动作之前。 例如:I was going out when a visitor came. (动词动作同时发生。)我正要出门,有客人来访。 I shall tell her the good news when she comes.她来时,我将告诉她这个好消息。 小试牛刀:I found mother cooking for me. I got home.(when)_______________________________________ He was listening to the radio when I home. (get) 2.while 引导的从句:表示“当……过程中”,强调某一段时间内主句和从句中谓语动词所表示的动作在同一时期发生。由于while从句表示一个持续的行为,所以从句中要用持续性动词,并且持续性动词常用进行时态。 例如:Keep an eye on my little sister while I am away.我不在时,请照看一下我的小妹妹。 While we were watching TV, Jim came in. 我们看电视的时候,Jim进来了。 小试牛刀:It started to rain. We were playing football.(while)_______________________________________ Lucy was cleaning the room Lily was listening to music. 3.as引导的时间状语从句:表示“当……的时候;一边……一边……;随着……”,其从句的主语与主句的主语往往是同一人或物。 例如:She sang as she worked. 她一边工作一边唱歌。=She was singing as she was working. I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。 小试牛刀: we walked, we talked. You will grow wiser you grow older. 4.before引导的从句:一般表示主句的动作发生在从句动作之前。 例如:I didn’t know any English before I came here. 我到这儿来之前,一点英语都不懂。 例如:I had written my report before my father came back. 小试牛刀:He bought the ticket he went to see the film. 5.after引导的从句:表示主句的动作发生在从句动作之后。 例如:After he locked the door, he left. 他锁上门后,就走了。 After he had finished his work, he played a game of chess with his friend. 他做完工作后,和朋友下了一盘棋。 小试牛刀:I will go out to play basketball with you. I finish my homework.(after) _______________________ _ He left the classroom he had finished his homework the other day. 6.since引导的从句: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。主句中的动词表示动作延续的情况,一般用现在完成时。如果主句中的动词表示的不是延续的动作而是表示目前的状态,可用一般现在时。 例如:Since he met this good friend, he has made great progress in his studies. 自从遇见了这个好朋友,他已在学习上取得了巨大的进步。 例如:It is twenty years since she joined the Party. 她入党二十年了。(主句中的动词表示的是状态,用现在时。) 小试牛刀:it is five years since we last time.(meet) Mr green has taught in that school since he (come) to China three years ago.

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 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”.

时间状语从句讲解与练习

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. 他小时候就常常试验一些新的设想。 2. When she came into my room, I was just reading a book. 她走进我房间时,我正在看书。 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。 5. He was on the point of leaving when someone knocked at the door. 他正要走,这时有人敲门。 6. I thought of it just when you opened your mouth. 就在你要说话的时候,我也想到了。 7. I had hardly[scarcely] closed my eyes when someone knocked at the door. 我刚一闭上眼,就有人在敲门了。

根据以上的例句,我们可以总结出一点:when 从句的A事件,相当于另一个事件B发生的时间点。也就是说,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。 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。 1. When I got to the airport, the guests had left. 当我赶到飞机场时,客人们已经离开了。 2. When he had finished his homework, he took a short rest. 当他完成作业后,他休息了一会儿。 3. Why do you want a new job when you have got such a good one already? 你已经找到如此好的工作,为何还想再找新的? 4. You shall borrow the book when I have

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。
