连词because用法详解

连词because用法详解

1.表示原因,语气较强,可用来回答 why 提出的问题。如:

A:Why do you love her? 你为什么爱她?

B:Because she is kind. 因为很善良。

2. because 除经常用于引导原因状语从句外,还可引出表语从句或用于强调句等。如:

It is because you’re eating too much.那是因为你吃得太多了。

It was because I wanted to buy a dictionary that I went to town yesterday. 我昨天是由于想买本字典而进城的。

3.汉语说“因为……所以……”,但英语却不能用 because…so…这样的结构。如:

因为我病了半年,所以把工作丢了。

误:Because I was ill for six months, so I lost my job.

正:Because I was ill for six months, I lost my job.

正:I was ill for six months, so I lost my job.

4.汉语说“之所以……是因为……”,英语可以类似以下这样的句型(用that比用 because 普通)。如:

The reason (why) I’m late is that [because] I missed the bus. 我迟到的原因是因为我没有赶上公共汽车。

传统语法认为这类句型不能用 because, 但在现代英语中用because 的情形已很普遍。

5.在not…because…这一结构中,not 有时否定主句,有时否定从句,具体视语境而定。一般说来,若 not 否定主句,最好在because 之前用逗号,否则会引起歧义,如下句在没有特定上下文时就有两种解释:

I didn’t go because I was afraid.

这个句子既可理解为“我没有去是因为怕”,也可理解为“我不是因为怕才去”。但是,如果because之前有副词just修饰,一般认为not是否定从句而不是主句。如:

You shouldn’t get angry just because some people speak ill of you.你不要因为有人说你坏话而生气。

6.有时可引导一个句子作主语,此时通常采用just because这样的形式,并且主句谓语动词通常(当然不是一定)为mean。如:

Just because you speak English doesn’t mean you can teach it.你会说英语并不意味着你能教英语。

Just because you’re old doesn’t mean you have to be idle.只是因为你年纪大了,这并不意味着你就应该懒散不活动。

Because you have words with your wife is no reason to smash up things. 你和你的妻子吵架并不能成为摔东西的理由。

7.用于构成复合介词because of,其后可接名词、代词、动名词、what 从句(但不能是that 从句或没有引导词的从句)等。如:

He is here because of you (that). 他为你(那事)而来这里。

We said nothing about it, because of his wife’s being there.因为他妻子在那儿,我们对此只字未提。

He left the company because of what the boss said at the meeting. 他离开了这家公司,是因为老板在会上讲的话。

8. because of通常用来引导状语,而用于不引导表语(引导表语时可用 due to)。如:

误:His absence is because of the rain.

正:His absence is due to the rain. 他因雨未来。

但是,若主语是代词(不是名词),则它引出的短语也可用作表语。如:It is because of hard work. 那是因为辛苦工作的原因。

It will be because of money. 那将都是因为钱的原因。

when做并列连词的用法

when 和引导时间状语从句的从属连词when 是不同的。这主要表现在以下几个方面: 1. 位置:when 引导时间状语从句时,该从句可放在主句之前也可放在主句之后;而并列连词when 只能位于两个分句之间,而且前面常常有逗号。例如:Come when you please. 你高兴来就来吧。(when 为从属连词)When I saw him,he was writing to a friend of his. 我看见他时,他在给一个朋友写信。(when 为从属连词)I was taking a walk,when I came across him. 我正在散步,突然碰见了他。 2. 意义:when 作从属连词用时,它所引导的从句表示主句中谓语动词动作发生的时间,即作“当……时”解;而并列连词when 连接的两个分句中,第一个分句表示的是背景,第二个分句表示的是一种突然的、意想不到的情况或过早发生的事情。when 通常含“这时突然”之义。例如:I was thinking of this,when I heard my name called. 我正想着这件事,突然听到有人叫我的名字。I had just fallen asleep,when the boor-bell rang. 我刚入睡,门铃突然响了起来。这种意义在孤立的句子中可以理解到,在文章中更能体会得到。如在“ I was wandering through the street when I caught sight of a tailor's shop ”一句中,“在街头漫步”只是“看见有家缝纫店”的时间,其后作者怎样走进缝纫店,想要什么样的衣服,怎样受到伙计的奚落,又怎样受到老板的奉承等情景均与“漫步街头”没有直接的因果关系。 3. 时态:when 引导的时间状语从句中可以根据句意的需要用一般现在时.一般过去时、过去进行时、分别说明现在,过去,甚至将来的行为;并列连词when 后面的分句中通常用非延续性动词的一般过去时,其前表时间的分句中可用:( 1 过去进行时表示过去某时间正在进行的动作。 例如: I was cooking when I heard her knocking at the door. 我正在做饭,突然听到她敲门的声音。 He was thinking about the problem,when an apple fell to the ground. 他正在思考这个问题,突然有一只苹果掉到了地上。 (2 )was /were going to,was / were about to,was / were on the point of 表示过去某一时间将要发生的动作。 例如: I was just going when he came in. 我正要走,这时他就进来了。 We were about to start when it began to rain. 我们刚要动身天就开始下起雨来了。 He was on the point of leaving,when someone knocked at the door. 他刚要走就有人敲门。 (3 )过去完成时表示过早发生的事情。请看下述两种场合: (a )过去完成时和含否定意义的hardly,scarcely,nearly 连用,和just,little 连用,或者与否定词not 连用时,表示“刚……,就……”的意思。 例如: I had hardly opened the door when he hit me. 我刚一开门他就打了我一下。 I had nearly reached the town,when the young man suddenly said very slowly,“ Do you speak English ”我快要进城了,年轻人突然慢慢地说:“你会讲英语吗” I had been there little more than a week when I set to work in earnest. 我到那儿还不超过一个星期就开始认真干起活来。 I had not been reading for half an hour when I heard steps outside.

as作连词的用法

一、as作连词的用法 1. as...as的用法 as...as意为"和……一样",表示同级的比较。使用时要注意第一个as为副词,第二个as为连词。其基本结构为:as+ adj./ adv. +as。例如: (1)This film is as interesting as that one.这部电影和那部电影一样有趣。 其否定式为not as/so +adj./ adv. +as。例如: This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。 若有修饰成分,如twice, three times, half, a quarter等,则须置于第一个as之前。例如: Your bag is twice as expensive as mine.你的袋子比我的贵一倍。 几个关于as...as的常见句型: (1)as...as possible Please answer my question as soon as possible.请尽快回答我的问题。 (2)as...as usual/before She looks as pretty as before.她看起来和以前一样漂亮。 (3)as long as... (引导条件状语从句) It took us as long as three years to carry out the plan.我们花了长达三年的时间才完成这项计划。 (4)as far as He walked as far as the railway station yesterday evening.昨天傍晚,他一直散步到火车站。 (5)as well as She cooks as well as her mother does.她烧菜烧得跟她母亲一样好。 一些带有as...as结构的常见短语归纳: as busy as a bee像蜜蜂一样忙碌 as easy as ABC像ABC一样容易 as deep as a well像井一样深 as light as a feather像羽毛一样轻 as soft as butter像黄油一样软 as rich as a Jew像犹太人一样富裕 2. as用作连词引导时间状语从句 as与when,while都是引导时间状语从句的从属连词,含义都是"当……的时候"。但它们有区别:用when时,从句的动作可以与主句的动作同时发生,也可以先于主句的动作发生;用while时,从句的动作为一过程,主句动作与从句动作同时进行或在从句动作过程中发生;用as时,主句和从句的动作同时发生,具有延续的含义。例如: (1)It was snowing when he arrived at the construction site.他到达工地时,天正在下雪。 (2)He was watching TV while his mother was cooking.他母亲做饭时他在看电视。 (3) You will grow wiser as you grow older.你会随着年龄的增长而越来越聪明。 3. as用作连词引导原因状语从句 as,because,since都可以表示因果关系,连接原因状语从句,含义是"因为,由于",但它们有区别:because表示的语气最强;as一般放在句首,语气较弱,较口语化;since常常用在书面语中,表示多为对方已知的、或稍加分析便可得知的原因,有时可译作"既然"。例如: (1) He will succeed because he is in earnest.他一定会成功,因为他很认真。 (2) Since you are so sure of it he”ll believe you.既然你对此如此有把握,他会相信你的。 (3) As rain has fallen, the air is cooler.因为下过雨,空气比较清爽。 4. as作连词引导让步状语从句 as与although (或though),however (或no matter how)等都可以引导让步状语从句,含义是"虽然,

并列连词when相关的句式归纳

并列连词when相关的句式归纳 2006年普通高等学校招生全国统一考试(辽宁卷)中有这样一道单项填空题:He was about halfway through his meal ___ a familiar voice came to his ears. A.why B.where C.when D.while 解析:答案是C。此处when作并列连词,表示“就在此刻(and just then)”“,突然(and suddenly)”,该句译为:“饭刚吃到一半儿的时候,熟悉的声音传到了他的耳朵里。” 这里when引导的并不是我们所认为的时间状语从句而是并列句。when的意思是这时而不是当什么时候。在这个句型中when所引导的从句恰恰是句意的重心,when在这里起到一个修辞的作用表示后一动作的发生的出乎意料,而前面一句是为后一句谓语动词的发生提供背景。when 为并列连词。在我们的教材中并不鲜见。如: I'd just about given myself up for lost when I was spotted by a ship. 我正感到绝望时,一艘船发现了我。【Unit 3 Book 3】 33. She had just finished her homework ___ her mother asked her to plactised playing the piano yesterday.【09福建卷】 A. when B. while C. after D. since 7. Tom was about to close the window ___ the attention was caught by a bird. 【10全国卷】 A. when B. if C. and D. till 1.be (just) about to do... when... She was just about to say something more when she noticed the sullen look on his face.她刚要再说些什么,却突然看到了他阴沉的脸色。 We were about to telephone you when your telegram arrived. 2.be (just) on the point of doing sth ... when... They were on the point of giving up when the captain encouraged them fiercely to save the ship. 就在他们快要放弃努力时, 船长鼓励他们竭尽全力挽救轮船。

连词的用法教案(一)(初中英语)

教学过程 一、复习预习 教师引导学生复习上节课所学的内容复习,(以提问、回顾的形式进行),针对上节课的作业进行讲评、订正、答疑,并通过简单的句子导入本节课所要学习的连词。 连词含义:连词是一种虚词,它不能独立担任句子成分而只起连接词与词,短语与短语以及句与句的作用。连词主要可分为两类:并列连词和从属连词。 二、知识讲解 知识点1:并列关系连词的用法 在句子中并列连词用来连接平行的词、词组和分句。常用的并列连词有:and,both…and,not only…but also,as well as,neither…nor等。 1. 【考查点】单个连词及固定搭配的用法。 如:They sat down and talked about something. 他们坐下来并且讨论一些事情。 She plays not only the piano, but (also) the guitar. 她不仅弹钢琴而且还弹吉他。 注意:not only… but also关联两个分句时,一个分句因有否定词not 而必须倒装。 Not only does he like reading stories, but also he can even write some. 他不仅喜欢读故事书,甚至能写一些。 2.【易错点】1) 并列结构中,or通常用于否定句,and用于肯定句。

2) 但有时and也可用于否定句。请注意其不同特点: There is no air or water in the moon. 在月球上没有空气和水。 There is no air and no water on the moon. 在月球上没有空气没有水。 在否定中并列结构用or 连接,但含有两个否定词的句子实际被看作是肯定结构,因此要用and。 知识点2:表示选择关系的连词 1.【考查点】选择关系的连词及固定搭配 or意思为"或则"。either…or意思为"或者……或者……"or else/ otherwise 否则 如:Which do you prefer, tea, coffee, or juice ? 你喜欢哪一个,茶,咖啡还是果汁? Either you or I am right. 你和我有一个是正确的。 Be silent, or else you will be kicked out. 保持沉默,否则你将会背开除。 I am tired, otherwise, I would play. 我很累,不然的话我就去玩了。 知识点3:表示转折或对比关系的连词 1.表示转折关系和对比关系的连词有but,while,yet,however等 2.【考查点】转折关系连词的用法 如:He is rich but unhappy. 他很富裕但不快乐。 Some people love cats, while others hate them. 有些人喜欢猫,而有些则讨厌他们。 She said she would be late, yet she arrived on time. 她说她将会迟到,然而他却准时到达了。 She does not like him, however, I like him. 她不喜欢他,但是我喜欢他。 They were not the bones of an animal, but (the bones) of a human being. 他们不是动物的骨头而是人类的。 注意:not 和but 后面的用词要遵循一致原则。 2.【易错点】but和however的区别。However后有逗号,but没有。 知识点4:表示因果关系的连词 1.【考查点】for因为,做并列连词使用时,是在对先行的句子补述原因或者理由, 以连接句子与句子,通常不置于句首。so, therefore 因此,then那么,因而。 如:He is absent today, for he is ill. 他今天缺席了因为他生病了。 He hurt his leg, so he couldn't play in the game. 他的腿受伤了,因此不能参加这个游戏。 知识点5:谓语动词单复数的判断 1.【考查点】句子有as well as,neither…or等连词时注意谓语动词的单复数。

as既可以用作连词

Just as the flying worm hit her face, she gave a loud cry. 4) 后接名词表示某一年龄段时,用as。如: As a young man(=When he was a young man), he was active in sports. 年轻时,他在运动上很活跃。 注意与when、while的用法区别: 1)when作"当……的时候"解,可以指较短的(一点)时间,也可指一段时间从句的动作可以与主句的动作同时发生,也可以先于主句的动作发生。如: When he was at college, he could speak several foreign languages. 他上大学时能讲好几门外语。 When the clock struck twelve, all the lights in the street went out. 当钟敲响12点时,街上所有的灯都熄灭了。 2)while从句中的动词是可延续性动词,表示一段较长的时间或一个过程,主句动作与从句
