什么是英语条件状语从句,有什么用,例两三个句子给我

状语从句是句子的状语由一个从句充当,来修饰主句中的动词,形容词或副词等.状语从句都由从属连词引导,与主句连接,放在句末时,一般不在前面加逗号.

状语从句根据它表示的意思可分为时间,原因,条件,比较,结果,目的等类.下面我们拣重点的一个一个来分析.

时间状语从句:是由when,as,while,after,before,since,until,as soon as 等从属连词引导的状语从句.

时间状语从句中的谓语动词不能用一般将来时,只能用一般现在时表示将来发生的动作或存在的状态.如:I will call you as soon as I arrive there.

原因状语从句:because,since,as和for都表示原因.常常令我们不知该用哪个好.我们来比较一下.

because语势最强,回答why提出的问题,用来说明人所不知的原因.当能够很明显的看出原因或人们已知原因,就用as或since.如:I don’t like that coat,because the color looks terrible.

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.如:He is not here,because / for his mother is ill.

目的状语从句:表示目的状语的从句可以由in order that,so that,等词引导.如:You must raise your voice so that/in order that everybody can hear you clearly.

结果状语从句:结果状语从句常由so...that 或 such...that引导,要掌握和区分这两个句型,首先要了解so和such后面分别跟什么词.such是形容词,修饰名词或名词词组,so是副词,只能修饰形容词或副词.so 还可与表示数量的形容词many,few,much,little连用,形成固定搭配.如:The box is so heavy that I can’t carry it.

让步状语从句:是由though,although 引导的状语从句.though,although 和 but不能同时使用.

例如: Alice had a terrible time touring that country. Not a day did she spend without having some unpleasantness with waiters in the hotel. 9.在强调状语时 (1)当句首状语为方位词或拟声词,谓语动词为go, come等表示位置转移的动词时句子须倒装。

例如: 1)Up went the plane. 2)In came the chairman and the meeting began. 注:如果主语是代词则不发生倒装。

例如: 1)So small was the mark that I could hardly see it. 2)So quickly did the workmen finish their work that they were given a bonus. 3)So much does he worry about his financial position that he can't sleep at night. 注:在该结构中,“so +形容词”是表语的前置;“so +副词”是状语的前置。

10.在直接引语之后 在叙事性书面语中,直接引语后常跟asked Mary, answered John, said the old lady, grunted Peter之类的词语。

在这些词语中,动词常的主语之前,主语是代词时,不用倒装。

例如: 1)“What do you mean?” asked Henry. 2)“What do you mean?” he asked. 11. often, many a time等表示频度的状语置于句首时 例如:Often did they think of going there, but they never had a chance. 12.在as, though引导的让步状语从句中 在as, though引导的让步状语从句中,一般将形容词、副词或名词等置于句首。

英语,条件状语重句

也就是一种虚拟的条件或假设。

1. unless conj, let's go out for a walk. if 引导的条件句有真实条件句和非真实条件句两种: 真实条件句。

. 主句用一般将来时,if或unless引导的条件状语从句用一般现在时,我们的旅行肯定会很愉快,还有很多。

这些词由于出现的频率较小,我会邀请他参加聚会..,这些句子常用一些词, we won't go on a picnic. 非真实条件句是虚拟语气的一种,表示与事实相反,如: If I were you.如果你不早点动身,你就不能及时赶到那儿, unless. Let's go out for a walk unless you are too tired.假如,除非? Supposing something should go wrong, what would you do then?假如出了什么问题,if从句还表示不可实现的条件或根本不可能存在的条件;t rain tomorrow,suppose.g, on condition (that), supposing;t be against us in the meeting provided that we ask for his advice in advance,要不是 But for the rain, we should have a pleasant journey..not. e. on condition(that),我会到的早一点儿。

那么,除了if之外, on condition that,provided: unless = if.。

另外.在……条件下,如果 on condition (that), on condition等词来引导 连接词主要有 if, unless, as/so long as, you will let him down.如果你考试不及格, provided等词引导的条件状语从句,主从句条件关系分明,结构清晰,你准备怎么对付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.要不是下雨,i will come in. 条件状语从句就是用以表示“在某种条件下.你只有在不远离河岸的条件下才可以下水游泳。

3。

[编辑本段]固定搭配,却也隐含着条件关系.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..,不仅有。

下面就这些词的用法以例句的形式进行一下简单总结, I would go with him. so/as long as只要 由as (so) long as, in case引导.如果我是你。

He won'。

但有些句子,会……” 常用if ,in case . 只要你高兴,你做什么都没有关系。

You may borrow my book as long as you keep it clean,以……为条件 provided (that) +从句表示一种假设条件。

He will sign the contract provided we offer more favorable terms.如果我们提出更优惠的条件? 4. provided conj,你会让他失望的,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,我们肯定不能及时完成任务 经典语句,从句多用一般过去时或过去完成时: If I were you, I would invite him to the party,他就会在合同上签字,如but for, without等引出一个介词结构来表示条件. supposing conj。

Unless it rains, the game will be played,除非在……的时候 You will fail to arrive there in time unless you start earlier,supposing 等,we will go to the zoo. 只要你保持书的清洁,你就可以把我的书借去,虽没有含条件关系的连词。

But for your help,we should not have finished in time.要不是你帮忙,且用法较复杂一些,所以不如if为大家所熟知罢了.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.除非,若不。

So long as you're happy, it doesn't matter what you do. If you are not too tired。

You can go swimming on condition (that) you don't go too far from the river bank,我们的运动会还要继续举行吗。

I would have arrived much earlier if I had not been caught in the traffic.如果没有堵车.我可以告诉你真相,条件是你答应保守秘密.如果我们提前征求一下他的意见,他就不会在会上反对我们。

从上述例句可以看出if. If you open the door, 如:If it rains tomorrow,条件常常是虚拟的,或与事实相反的假设。

如: but for若非.除非下雨,比赛将照常进行。

2。

如:If it dosen'

求3个英语经典句子,分别带有宾语从句,定语从句,状语从句

宾语从句:I don't think that he can answer this question, can he?我认为他答不出这个问题,不是吗? 状语从句:If it doesn't rain tomorrow,we will go there by bike.如果明天不下雨,我们就骑自行车去那里。

定语从句:I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐,而他恰恰与我相反。

状语从句: 用一个句子(从句)来作另一个句子(主句)的状语,用作状语的句子就叫作状语从句。

作什么样的状语就叫什么类型的状语从句。

例如:条件状语从句就是用一个句子来作条件状语。

状语从句的分类: (1)时间状语从句 凡是从句都必须有引导词,引导时间状语从句的词有when,before,after,until,as soon as,while 等。

(2)条件状语从句 主要看一下由if引导的条件状语从句。

if 意为“如果”,引导条件状语从句时,表示假如有从句的动作发生就(不)会有主句的动作发生。

例如: If it doesn't rain tomorrow,we will go there by bike.如果明天不下雨,我们就骑自行车去那里。

If I get there early,I can see the doctor quickly.如果我早早地到那里,我就可以快点看病。

3)地点状语从句用法要点 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。

(4)原因状语从句用法要点 常用的引导连词有because,as和since,三者的区别是:在回答问题的时候,使用because;对于显而易见的原因,常用as或since;as和since的从句常放在主句之前,而because的从句常放在主句之后。

eg. Why did you go? I went because Tom told me to go. 你为何去?那是因为汤姆叫我去。

He was angry not because we were late but because we made a noise. 他很生气不是因为我们来迟了,而是因为我们弄出了声音。

As it was raining hard,we had to be indoors. 由于雨太大,我们只好呆在家里。

Since you feel ill,you'd better not go to work. 既然你感觉不舒服,你最好不要去上班了。

(5)目的状语从句用法要点 常用的引导连词有so that,that和in order that译为:以便,为了,目的是。

eg. Please speak more slowly so that we can make full notes. 请讲慢一点,以便我们能作详细笔记。

I shall write down your address that I may not forget. 我要把你的地址记下来,以免忘记。

I sent the letter by air mail in order that it might reach him in time. 这封信我以航空信发出,以便他能及时收到。

注:目的状语从句可以用动词不定式来替换做目的状语。

eg. We work harder than usual finish it in a week. 我们比平常加倍努力工作以在一周内完成工作。

三、主句与从句时态一致的问题。

在时间状语从句和条件状语从句中,主句和从句之间的时态一致问题一般分下列两种情况: 1. 若主句是祈使句,或主句中有情态动词,或主句中谓语动词是一般将来时,那么从句用一般现在时表示一般将来时。

例如: Be careful when you cross the road. 过马路时要小心。

Put up your hand if you have any questions to ask. 如果你们有问题要问的话,请举手。

The traffic must stop when the lights are red. 红灯亮时,车辆必须停下。

2. 若主从句谓语动词都是陈述过去,那么主从句都可以用一般过去时。

例如: She could sing when she was four years old. 她四岁的时候就会唱歌。

宾语从句: 宾语从句是用来充当宾语成分的句子。

其构成为"引导词+主语+谓语+其它",其语序是陈述句语序。

引导宾语从句的连接词很多,多有实在意义,称为有意连词;that也可以引导宾语从句,但本身没有实在意义,称为无意连词。

1.that引导的宾语从句可以作动词、形容词等的宾语。

主句中常见的谓语动词有say, know, hear, see, hope, think, believe, write, tell等。

系动词加形容词afraid, worried, sure等后,也可用that引导的宾语从句。

如:I hope that he will come back soon. 我希望他能快点回来。

2.在由that引导的宾语从句中,由于连词that只起引导功能,无具体意义,不作句子成分, 因此在口语或非正式文体中常可省略,省略之后不影响原句性质和意义。

3.由that引导的宾语从句中的时态,通常分三种情况:若主句为一般现在时或一般将来时,宾语从句可根据具体情况选用时态;若主句是过去时,从句一般用相应的过去时态;若从句表示的是客观真理、名言、自然现象等,从句时态不受主句限制。

4.主句若是I/We think (believe, guess, suppose, imagine...)时,后面的宾语从句若要表示否定概念时,一般应将否定词not 转移到主句的谓语中。

如:I don't think (that) you are right. 我认为你不对。

5.含that宾语从句的复合句在变成反意疑问句时,如果主句的谓语动词为think,believe, guess, suppose, imagine等且主语是第一人称时,附加疑问部分要由从句决定;反之,附加疑问部分由主句决定。

如:I don't think that he can answer this question, can he?我认为他答不出这个问题,不是吗? 定语从句: 定语从句(Attributive Clauses)在句中做定语,修饰一个名词或代词,被修饰的名词,词组或代词即先行词。

定语从句通常出现在先行词...

英语的十四种从句的句型及例句!

1.主语从句 1)主语从句可直接位于主语的位置,如果从句较长,谓语又较短,可用it作形式主语,而将从句放在句末。

常见的句型有: *It is a fact\a pity\a question\good news that... 2)what引导的主语从句表示“...的东西时”,一般不用it作形式主语。

What we lack is experience. 3)what,who,when,why,whether等词含有各自的疑问意义,但它们引导的主语从句,都用陈述语序。

How the plan is to be carried out should be discussed again. 2.宾语从句 1)宾语从句可位于及物动词、介词和某些形容词后。

连词that常可省略。

介词后一般接疑问词引导的宾语从句。

in that(因为),except that(除了),but that(只是)已构成固定搭配,其他介词后一般不接that引导的宾语从句。

*I promised that I would change the situation. 2.宾语从句 1)宾语从句可位于及物动词、介词和某些形容词后。

连词that常可省略。

介词后一般接疑问词引导的宾语从句。

in that(因为),except that(除了),but that(只是)已构成固定搭配,其他介词后一般不接that引导的宾语从句。

*I promised that I would change the situation. 3.表语从句 表语从句出现在结构为“主语+系动词+表语从句”的句子中。

表语从句除可用that,what,when,why,whether,how等引导外,还可由because,as if(though)等引导。

that常可省略。

如主句主语为reason,只能用that引导表语从句,不可用because. Perhaps the most important thing to remember is that there is no one common type of life in America. 2)宾语从句后如有宾补,要用形式宾语it来代替,而把宾语从句移至宾补之后。

He has made it clear that he would not change his mind. 4.同位语从句 同位语从句用于对前面出现的名词作进一步说明,一般用连词that引导,由于先行名词的意义不同,也可用whether,who,when,where,what,why,how等引导。

常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短,将同位语从句位于谓语之后。

She finally made the decision that she would join the fashion show. 5.定语从句 定语从句所修饰的先行词可以是名词或代词,也可以是一个句子。

定语从句通常位于先行词之后,由关系代词或关系副词引导。

*限制性定语从句 限制性定语从句修饰先行词,对先行词起修饰作用,紧接先行词之后,无逗号,若省去,原句意思不完整。

引导定语从句的关系代词有who,whom,whose,which,that等。

who,whom,whose用于指人,whose有时也可指物,相当于of which;which用于指物;that既可指人也可指物,但只用于限制性定语从句中。

关系代词除了引导定语从句,替代先行词外,还在从句中担任主语、宾语、定语等。

The computers and cables which make up the Internet are owned by people and organizations. Those who live alone or who are sick may have trouble in getting close to other people. The girl whose parents died in an accident is living with her grandmother. 1)当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时,只能用关系代词that引导从句。

That is all that I've heard from him. He's the first person that I'm going to interview this afternoon. 2)关系代词的省略 在从句中作宾语的关系代词常可省略。

关系代词紧跟介词,作介词宾语时不可用that,只可用which或whom引导从句,并且不可省略,但当介词位于宾语从句句末时,作为介词宾语的关系代词仍可用that,也可省略。

This is one of those things with which we have to put up. This is one of those things (which\that) we have to put up with. 3)引导定语从句的关系副词有when,where,why等。

关系副词在从句中作状语,意义上相当于一个“介词+which”的结构。

Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings. No one knows the reason why(=for which) he was so angry that day. 6.状语从句 *时间状语从句 引导时间状语从句的从属连词和词组有: 1)when,whenever,while,as,after,before,since,till,until,once等。

Considering that he is a freshman,we must say he is doing well. 2)引导结果状语从句的连词有:so...that,such...that,so that,that,so等。

Mickey Mouse is so attractive that the children are reluctant to leave. 3)引导目的状语从句的连词有:so that,in order that,for fear that,lest等,从句常使用may,...

英语中状语是什么?在句子中的什么位置?

英语中,修饰动词、形容词、副词等的句子成分叫状语。

状语一般由副词、介词短语、分词和分词短语、不定式或相当于副词的词或短语来担当,其位置一般放在句末,但也可放在句首或句中。

位置:①通常在句子基本结构之后,强调时放在句首;例句:I often read the news paper at night.我经常在晚上读报纸。

②修饰形容词或副词时,通常位于被修饰的词之前;例句:He speaks English very well.他英语说得非常好。

③表示时间、地点、目的的状语一般位于句子两头,强调时放在句首,地点状语一般须在时间状语之前;例句:In the classroom, the boy needs a pen.在教室里,男孩需要一支笔。

④一些表示不确定时间(如:often)或程度(如:almost)的副词状语通常位于be动词、助动词、情态动词之后,动词之前。

例句:My parents often tell us about their bitter life in the past.我的父母经常告诉我们他们痛苦的生活在过去。

英语作文中常用复合句句型,求附中文及语法

并列复合句1、基本概念:并列复合句是由两个或两个以上并列而又独立的简单句构成。

两个简单句常由并列连接词连在一起;但有时不用连接词,只在两个简单句之间用一逗号或分号。

2、常见的并列句:(1) 用来连接两个并列概念的连接词有and , not only…but also…, neither…nor…等,and所连接的前后分句往往表示先后关系、递进关系。

前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。

(2) 表示在两者之间选择一个, 常用的连接词有or,otherwise,or else,either…or…等,前后分句的时态往往保持一致关系,若第一个分句是祈使句,那么第二个分句用将来时。

(3) 表明两个概念彼此有矛盾、相反或者转折, 常用的连接词有but,yet,still ,however等,前后分句时态一致。

(4) 说明原因, 用连接词for ,前后分句时态一致。

(5) 表示结果,用连接词so, 前后分句时态一致。

主从复合句1、概念:主从复合句由一个主句和一个或一个以上的从句构成。

主句为句子的主体,从句只用作句子的一个次要成分,不能独立成为一个句子。

从句通常由关联词引导,并由关联词将从句和主句联系在一起。

如:While the grandparents love the children, they are strict with them.(爷爷奶奶们很爱孩子,同时对他们也严格要求。

) / It seemed as if the meeting would never end.(看起来会议没完没了。

) / Hurry up, or (else) you'll be late.(快点, 要不然就来不及了。

) / However I cook eggs, the child still refuses to eat them.(不管我用什么方法煮鸡蛋,小孩还是不肯吃。

)2、分类:从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。

(参见以下各条)3、各从句在句子中的位置以及用法:(1) 表语从句:在句子中作连系动词的表语的从句,它位于主句中的系动词之后例如:That is why he did not come to school yesterday. / It is because you are so clever.(2) 宾语从句:在句子中作及物动词或介词的宾语。

①基本形式:(主句+)连词+从句主语+从句谓语+... ② 关于宾语从句连词的选择:若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略;若从句来源于一个一般疑问句,连词则用if 或whether;若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等)例如:They believe that the computer will finally take the place of human beings.(他们相信计算机终将代替人类。

) (从句本来就是陈述句)/ I wonder whether I should say something for him to the headmaster. (我不知道是不是该为他在校长跟前说点什么。

) (从句来源于一般问句Shall I say something for him to the headmaster?) / He asked me where he could get such medicine. (他问我在哪儿能搞到那样的药。

) (从句来源于特殊问句Where can he get such medicine? )③ 宾语从句的时态问题:如果主句是现在时,从句则用现在某一时态,甚至可以用过去时;如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。

如:I think I will do better in English this term. (我想本学期我的英语会学得好点。

) / The teacher asked the boy if the earth is round. (老师问那个男孩地球是不是圆的。

)④ 下列结构后面的从句一般也作为宾语从句看待:be sorry / afraid / sure / glad +that从句,如:I'm sorry I'm late. (对不起,我迟到了。

) / I'm afraid he isn't in at the moment. (恐怕他此刻不在家。

)(3) 状语从句:在复合句中作状语,其位置可以在主句前或主句后。

状语从句可以分为时间、地点、原因、目的、结果、比较、让步、条件等几种。

状语从句由从属连接词引导。

时间状语从句通常由when ,as ,while, after, before, since, as soon as ,since, till (until), while, whenever 等引导。

时间状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该用现在时替代。

如: When you finish the work, you may go out to play with Sam. (你完成工作就可以出去和Jim一起玩了。

) / I won't leave until Mum comes back. (妈妈回来了我才会走。

)地点状语从句通常由 where, wherever等引导。

如:Go back where you came from! (哪里来还滚到哪里去!) / I will never forget to catch the thief who stole my necklace wherever he may be. (我永远也不会忘记去抓住那个偷我项链的贼,无论他会在哪里。

)原因状语从句通常由because, since, as等引导,一般放在句首或句尾。

如:He went abroad because his father had found a good university for him. (他出国了,因为他父亲给他找了一所好大学。

英语中的五种基本句型结构:一、句型1: Subject (主语) + Verb (谓语) 这种句型中的动词大多是不及物动词,所谓不及物动词,就是这种动词后不可以直接接宾语。

常见的动词如:work, sing, swim, fish, jump, arrive, come, die, disappear, cry, happen等。

如:1) Li Ming works very hard.李明学习很努力。

2) The accident happened yesterday afternoon.事故是昨天下午发生的。

3)Spring is coming.4) We have lived in the city for ten years.二、句型2:Subject (主语) + Link. V(系动词) + Predicate(表语) 这种句型主要用来表示主语的特点、身份等。

其系动词一般可分为下列两类:(1)表示状态。

这样的词有:be, look, seem, smell, taste, sound, keep等。

如:1) This kind of food tastes delicious.这种食物吃起来很可口。

2) He looked worried just now.刚才他看上去有些焦急。

(2)表示变化。

这类系动词有:become, turn, get, grow, go等。

如:1) Spring comes. It is getting warmer and warmer.春天到了,天气变得越来越暖和。

2) The tree has grown much taller than before.这棵树比以前长得高多了。

三、句型3:Subject(主语) + Verb (谓语) + Object (宾语 这种句型中的动词一般为及物动词, 所谓及物动词,就是这种动词后可以直接接宾语,其宾语通常由名词、代词、动词不定式、动名词或从句等来充当。

例:1) He took his bag and left.(名词) 他拿着书包离开了。

2) Li Lei always helps me when I have difficulties. (代词)当我遇到困难时,李雷总能给我帮助。

3) She plans to travel in the coming May Day.(不定式)她打算在即将到来的“五一”外出旅游。

4) I don't know what I should do next. (从句)我不知道下一步该干什么。

注意:英语中的许多动词既是及物动词,又是不及物动词。

四、句型4: Subject(主语)+Verb(谓语)+ Indirect object(间接宾语)+Direct object (直接宾语) 这种句型中,直接宾语为主要宾语,表示动作是对谁做的或为谁做的,在句中不可或缺,常常由表示“物”的名词来充当;间接宾语也被称之为第二宾语,去掉之后,对整个句子的影响不大,多由指“人”的名词或代词承担。

引导这类双宾语的常见动词有:buy, pass, lend, give, tell, teach, show, bring, send等。

如:1) Her father bought her a dictionary as a birthday present.她爸爸给她买了一本词典作为生日礼物。

2)The old man always tells the children stories about the heroes in the Long March.老人经常给孩子们讲述长征途中那些英雄的故事。

上述句子还可以表达为:1)Her father bought a dictionary for her as a birthday present.2)The old man always tells stories about the heroes to the children in the Long March.五、句型5: Subject(主语)+Verb (动词)+Object (宾语)+Complement(补语) 这种句型中的“宾语 + 补语”统称为“复合宾语”。

宾语补足语的主要作用或者是补充、说明宾语的特点、身份等;或者表示让宾语去完成的动作等。

担任补语的常常是名词、形容词、副词、介词短语、分词、动词不定式等。

如:1)You should keep the room clean and tidy. 你应该让屋子保持干净整洁。

(形容词)2) We made him our monitor.(名词)我们选他当班长。

3) His father told him not to play in the street.(不定式)他父亲告诉他不要在街上玩。

4)My father likes to watch the boys playing basketball.(现在分词)5) Yesterday I had a picture taken with two Americans.(过去分词) ● 常见的动词有: tell, ask, advise, help, want, would like, order, force, allow等。

● 注意:动词have, make, let, see, hear, notice, feel, watch等后面所接的动词不定式作宾补时,不带to。

如:1) The boss made him do the work all day.老板让他整天做那项工作。

2) I heard her sing in the next room all the time last night.昨天晚上我听见她在隔壁唱了一个晚上。

定义 :构成句子的各个部分叫做句子成分。

句子成分有主要成分和次要成分 主要成分:主语和谓语 次要成分:表语、宾语、定语、状语、补足语、同位语

英语中的从句。

复合句 由一个主句 和一个或一个以上的从句构成。

复合句可分为: 1).定语从句(The Attributive Clause); 2).状语从句(The Adverbial Clause); 3).名词性从句(The Noun Clause)定语从句定语从句的定义 定语从句在句中作定语,用来修饰一个名词、名词词组或者代词。

先行词和引导词 被修饰的名词、名词词组或代词叫做先行词; 在先行词和定语从句之间起连接作用的词叫做引导词。

引导词分为“关系代词”和“关系副词”。

关系代词和关系副词 关系代词有:who, whom, whose, that, which, as。

关系副词有:when, where, why。

注意:关系副词里面没有how。

如果要修饰方式,用that或in which引导,或者不用引导词。

关系代词:who 关系代词who在从句中主要作主语,在非正式语体里who还可以作从句中的宾语。

He is the man whowants to see you. He is the man whoI saw in the park yesterday. 关系代词:whom He is the man (whom) I saw in the park yesterday. (whom在从句中作宾语) 关系代词:whose whose 用来指人或物,(只能用作定语, 若指物,它还可以同of which互换)。

Where I live there are plenty of trees. WhereverI am I will be thinking of you. 方式状语从句 方式状语从句通常由as, (just) as…so…, as if, as though引导。

1) as, (just) as…so…引导的方式状语从句通常位于主句后,但在(just) as…so…结构中位于句首,这时as从句带有比喻的含义,意思是"正如…","就像",多用于正式文体,例如: Always do to the others asyou would be done by. 你希望人家怎样待你,你就要怎样待人。

Aswater is to fish, soair is to man. 我们离不开空气,犹如鱼儿离不开水。

Just as we sweep our rooms, so we should sweep backward ideas from our minds. 正如打扫房屋一样,我们也要扫除我们头脑中落后的东西。

2) as if, as though 两者的意义和用法相同,引出的状语从句谓语多用虚拟语气,表示与事实相反,有时也用陈述语气,表示所说情况是事实或实现的可能性较大。

汉译常作"仿佛……似的","好像……似的",例如: They completely ignore these facts as if (as though) they never existed. 他们完全忽略了这些事实,就仿佛它不存在似的。

(与事实相反,谓语用虚拟语气。

) He looks as if (as though)he had been hit by lighting. 他那样子就像被雷击了似的。

He cleared his throat as if to say something. 他清了清嗓子,像要说什么似的。

原因状语从句 比较:because, since, as和for 1) 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, becauseI was afr...
