定语从句先行词怎么判断

关于先行词定语从句所修饰、限定的词叫先行词。作定语的句子就叫作定语从句。定语从句通常跟在和它发生关系的先行词之后，它与先行词有着不可分割的联系。它通常是由关系代词(who，whom，whose，that，which，as)和关系副词(where，when，why，how)来引导。关系代词、关系副词在从句中需担当成分，但无实际意义。初中阶段我们只要理解who，that，which这几个关系代词所引导的定语从句即可。1.关系代词who。关系代词who在从句中作主语，它的先行词是指人的名词或代词。例如：(1)Findtheboywhoiswearingaredshirt.找出穿红衬衫的那个男孩。(先行词是theboy)(2)HewhodoesnotreachtheGreatWallisnotatrueman.不到长城非好汉。(先行词是He)2.关系代词that。关系代词that在从句中可作主语、宾语、表语。作宾语时，that可省略。它的先行词可以是指物的名词或代词，也可以是指人的名词或代词。例如：(1)Shetoldhermotherallthathadhappened.她把所发生的事情都告诉了她的母亲。(先行词是all，that在从句中作主语)(2)I”llbuyyouthebike(that)yousawintheshopyesterday.我要给你买昨天你在商店里看到的那辆自行车。(先行词是thebike，that在从句中作宾语)(3)Thevillageisnolongerthevillagethatitwasbefore.这个村子不再是从前的那个村子了。(先行词是thevillage，that在从句中作表语)(4)Hethatwantstoeatthefruitmustclimbthetree.想吃果子的就得爬树。(先行词是指人的代词he，that在从句中作主语)3.关系代词which。关系代词which在从句中作主语或宾语，其先行词是指物的名词或代词。例如：(1)Theyfirstwenttoalargeroomwhichlookedlikeashop.他们首先到一个很大的看起来像个商店的房间去了。(先行词是指物的名词alargeroom，which在句中作主语)(2)Haveyougotanythingwhichyou”dliketobuy？你有想要买的东西吗？(先行词是指物的代词anything，which在从句中作宾语)事实上，定语从句是一个较为复杂的语法项目。

来自科学教育类芝麻团 推荐于 2017-11-22先行词:是在定语从句中,被定语从句所修饰的名词.例如: He is a teacher who teach our English.在这里定词从句who teach our English是来修饰前面的名词teacher.所以teacher就是一个先行词.

一、关系代词（在句中作主语、宾语或定语） 1.that既可代表事物也可代表人,which代表事物；它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语也可以省略.[eg：this is the book （which）you want.]而且,如果which在从句中作“不及物动词＋介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置 2.which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢 3.代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括当先行词是anything,everything,nothing ,none等不定代词时,或者是由every,any,all,some,no,little,few,much等修饰时等,这时的that常被省略 还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时,都只能用that 4.who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语 5.whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物,当它引导的从句修饰物体时,可以与 of which 调换,表达的意思一样. 二、关系副词（在句中作状语） 关系副词=介词+关系代词 why=for which where=in/ at/ on/ ...which (介词同先行词搭配) when=during/ on/ in/ ...which (介词同先行词搭配) 1.where是关系副词,用来表示地点的定语从句. 2.when引导定语从句表示时间〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导. By the time you arrive in London,we will have stayed there for two weeks.I still remember the first time I met her.Each time he goes to business trip,he brings a lot of living necessities,such as towels,soap,toothbrush etc. 3.当从句的逻辑主语是some,any,no,somebody,anybody,nobody,something,anything,everything或nothing时,常用there is来引导

什么是先行词？ 先行词是定语从句的引导词.在定语从句中充当一定的成分. This is the book which I am looking for.中的which. He is Mr. Robertson who s from England. 中的who. 先行词是定语从句修饰的那个词并不在从句中直接出现 出现在定语从句的前面 比如 He is the man who came from China. who came from China－－从句 the man---先行词 但是它们中间也有插入其他成分的情况， 所以要找到定语从句， 然后看它修饰的是哪一个词。 ps：插入成分一般两侧都有逗号隔开， 形式上还是很好区分的啊。 先行词是什么 您好，很高兴为您解答 简单的说，被宾语或从句修饰的词就是先行词。 怎么找先行词？？？ 先说下定义啊： 定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。 关系词 引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等，绝对没有what；关系副词有where, when, why等。关系词常有3个作用： ①连接作用，引导定语从句。 ②代替主句中的先行词，甚至可能是主句中的一部分或者整个主句。 ③在定语从句中充当一句子成分。 个人认为定语从句也是从句中比较简单的一种了，掌握好规律其实是不会做错的，我觉得要注意的有两点：一点就是找对先行词和关系词，那先行词就是主句中的那个词，基本都是名词或者词组，要点就是在从句中关系词被先行词替代了句子还是通顺。 比如说：Is he the man who wants to see you？这句话，主句就是is he the man，他是那个人吗？这句话就完整了。从句是who wants to see you。这句话的先行词主句里找一下，离开关系词who最近的就是man，就光一个单数的单词是不行的，要么是复数要么有个冠词，所以前面的the也要一起。那先行词就是the man，验证一下替换掉who，那就变成the man wants to see you。这个人想见你。句子通顺。就没错了。 再举个例子：The package which you are carrying is about to e unwrapped.这句话有一些难度了，主句被一刀劈开了，还是可以找到的，the package is about to e unwrapped.找主句当然要找谓语，一个谓语are跟在which后面，一个is远开很多，所以is那个应该是主句。从句就是which you are carrying。which后面跟的是you，代词也就是主语，那说明这句句子语序是变了的，根据意思可以看到“这个你在拿着”这里的这个是宾语，所以正确语序应该是“你在拿着这个”which在从句里作宾语，那作宾语的关系词是可以省略的，所以这里which可有可无，那没有的时候找出这句从句就更有难度一点。我们找到which前面的the package也就是先行词，带入you are carrying the package你在拿着包裹。这句话的意思就是你在拿着的包裹快要散开了。 了解了这个方法，应该找到先行词和关系词不难。 第二个点就是从句部分要语法正确。 语法正确有两个含义，一个是主谓一致。比如刚刚的第一个例句，先行词是the man，那关系词作主语，谓语当然应该用第三人称单数。 还有一个就是宾语从句先行词是短语，是时间啊地点啊，那就要很小心了，从句当中是应该用that、which还是用when，where，关键看副词。 比如：I still remember the place where I met her 我仍旧记得我第一次遇见她的地方。 这里的先行词就是the place。这里为什么要用where呢，因为I met her这个从句已经完整了，这个the place没有地方加，where是什么呢就是在什么地方，这个介词就隐藏在where中，还原句子就是I met her at the place。如果句子不是这样写的，变成I still remember the place which......

先行词，就是在定语从句中，被定语修饰的这个名词。如：He is the man who often helps us. 他就是经常帮助我们的那个人。 the man 是先行词 who often helps us 这是定语从句。

问题一：定语从句 先行词是不定代词时要用that 吗，someone 怎么后面又用who 难点分析 （一）限制性定语从句只能用that的几种情况 1．当先行词是anything, everything, nothing (something除外), few, all, none, little, some等代词时，或者是由every, any, all, some, no, little, few, much等修饰时 (1) Have you takendown everything that Mr. Li has said? (2) There seems tobe nothing that seems impossible for him in the world. (3) All that canbe done has been done. (4) There islittle that I can do for you. 注意：当先行词指人时，偶尔也可以用who (4) Any manthat/.who has a sense of duty won”t do such a thing. 2.当先行词被序数词修饰 (1) The firstplace that they visited inLondonwas the Big Ben. 3.当先行词被形容词最高级或比较级修饰时 (1) This is thebest film that I have seen. 4.当先行词被the very, the only修饰时 (1) This is thevery dictionary that I want to buy, (2) After the firein his house, the old car is the only thing that he owned. 当先行词指人时，偶尔也可以用who (3) Wang Hua isthe only person in our school who will attend the meeting/ 5.当先行词前面有who, which等疑问代词时 (1) Who is the manthat is standing there? (2) Which is theT-shirt that fits me most? 6.当先行词既有人，也有动物或者物体时 (1) Can youremember the scientist and his theory that we have learned? 只用which, whom 1. .当先行词有限定性修饰词时 what was the nameof the war in theUSAwhich lasted 5 years? 2. 当先行词是one, ones, anyone,等时用who;those做先行词时，指人用who, 指物用which Those who want togo to the Great Wall sign up here. He who has never been to the Great Wall is not a true man. ...>>

被定语从句修饰的词叫做先行词。如：I prefer music that has great lyrics. 句中的music，被that引导的定语从句修饰，它就是先行词。

只能用that,见如下第一点：限制性定语从句只能用that 的几种情况 1．当先行词是anything,everything,nothing (something 除外),few,all,none,little,some 等代词时,或者是由every,any,all,some,no,little,few,much 等修饰时 (1) Have you taken down everything that Mr.Li has said?(2) There seems to be nothing that seems impossible for him in the world.(3) All that can be done has been done.(4) There is little that I can do for you.注意：当先行词指人时,偶尔也可以用who (4) Any man that/.who has a sense of duty won"t do such a thing.2.当先行词被序数词修饰 (1) The first place that they visited in London was the Big Ben.3.当先行词被形容词最高级修饰时 (1) This is the best film that I have seen.4.当形容词被the very,the only修饰时 (1) This is the very dictionary that I want to buy,(2) After the fire in his house,the old car is the only thing that he owned.当先行词指人时,偶尔也可以用who (3) Wang Hua is the only person in our school who will attend the meeting/ 5.当先行词前面有who,which等疑问代词时 (1) Who is the man that is standing there?(2) Which is the T-shirt that fits me most?6.当先行词既有人,也有动物或者物体时 (1) Can you remember the scientist and his theory that we have learned?

先行词是名词或代词,如果名词或代词后面有修饰它们的句子且它们在句中充当某一成分,它们就是先行词.把先行词还原到从句中,就能判断做什么成份.如:IwillneverforgetthedaywhenIfirstwenttoschool.(先行词是day)从句=Ifirstwenttoschoolontheday.(ontheday在从句中作状语=when)

先行词是被定语从句所修饰的对象。在定语从句中充当一定的部分。之所以称它为先行词，是因为修饰它的定语从句总是放在它之后，先行词总是出现在定语从句之前，而不同于普通形容词修饰名词时，形容词位于名词之前。 判断定语从句先行词 定语从句的先行词可以是词，也可以是短语，更可以是句子。我们判断定语从句的先行词到底是谁，不能简单的去看定语从句关系词前的名词是谁，而是要更多地去看定语从句的语义，通过语义判断关系词应该指代的是谁，进而判断出先行词具体的内容。 （1）Behaviorists, in contrast, say that differences in scores are due to the fact that blacks are often deprived of many of the educational and other environmental advantages that whites enjoy.相反，行为主义者认为，成绩的差异是由于黑人往往被剥夺了白人在教育及其它环境方面所享有的许多有利条件。（在这个句子中最后一个that引导定语从句修饰advantages，advantage就是先行词） （2）He likes climbing hills, which is a good exercise.他爱爬山，爬山是一种好的锻炼方式。（这个句子中which定语从句显然修饰的是climbing hills这个动名词短语，所以climbing hills是先行词。） （3）This trend began during the Second World War，when several governments came to the conclusion that the specific demands that a government wants to make of its scientific establishment cannot generally be foreseen in detail.这种趋势始于第二次世界大战期间，当时一些国家的政府得出结论：政府向科研机构提出的要求通常是无法详尽预见的。（在这个句子当中，when引导定语从句修饰the Second World War名词短语，所以此名词短语是先行词。） （4）He is quite lazy, which is known to all his neighbors.他很懒，邻居们都知道。（这个句子which修饰的对象只能是he is quite lazy整个句子，所以句子是先行词。） （5）The food supply will not increase nearly enough to match this, which means that we are heading into a crisis in the matter of producing and marketing food.食品供应不会增加来满足这个要求,这意味着我们在生产和销售食品上面临危机。（这个句子中which引导定语从句修饰前面The food supply will not increase nearly enough to match this整句话。所以先行词是这整句话。）

1．关系代词有：that,which,who,whom,在定语从句中作主语、宾语或表语，whose 作定语。代人的有：who,whom,whose,that；代物的有：that,which,whose.例如： The man who helped you is Mr White.(who代人，在定语从句中作主语) That is the person(whom/who/that) you want to see.(whom,who,that代人，在定语从句中作宾语，可省略) I"m not the fool(that) you thought me to be.(that代人，在定从中作表语) A dictionary is a useful book which(＝that) tells us the meaning of words(which 或that代物，在定从中作主语)2．关系副词有：when(指时间)，where(指地点),why(指原因)，在定语从句中作状语。例如：Would you suggest a time(when) we can have a talk?(when可省略)The house where they live is not very large./This is the reason why he did not came to the meeting.注意：不是表时间的先行词都用when引导定从，不是表地点的先行词都用where引导定从。例如：We"ll visit the factory which(＝that) makes radios.(which或that在定从中作主语，where不可用主语，故不可用)They still remember the happy days(which/that) they spent in Beidaihe.(which或that在定从中作spent的宾语，when不可作宾语，故不可用)

定语从句的先行词就是定语从句修饰的那个名词，可以是句子中的主语、宾语。

由于定语从句是最长的定语，往往放在所有后置定语的最后。后置定语就是像介词短语这种。然后说定语从句

定语从句中有6种情况只用关系代词who,不用that的情况，这便是其一—— 先行词为those,one,ones,anyone,people等时。 eg):Those who are from Qingdao come this day.Anyone who breaks the law should be punished. （另：某些不懂的人就不要误导学生了！！）还有就是不要混淆了什么时候用that什么时候用who.定语从句，一个简单句跟在一名词或代词后(先行词)进行修饰限定，就叫做定语从句。在主句中充当定语成分。 被修饰的词叫先行词。定语从句不同于单词作定语的情况，它通常只能放在被修饰的词(即先行词)之后。定语从句由关系词(关系代词、关系副词)引导，关系代词、关系副词位于定语从句句首。

看从句缺主语还是宾语

定语从句：在复合句中修饰名词或代词的从句. 先行词：被定语从句修饰的名词或代词. 位置：定语从句必须放在先行词之后. This is the doctor who saved the boy"s life. 这里的先行词是 the doctor 先行词可以是时间、地点、人物等

I like music(先行词） that （引导词）I can sing along with,Rosa likes music (先行词）that（引导词）is quiet and gentle.Ilove singers (先行词）who（引导词） write their own music.We prefer music(先行词） that（引导词） has great lyrics.

先行词是定语从句的引导词前面的被定语从句所修饰的名词、代词.在定语从句中充当一定的成分. 我们可以这样认为, 之所以称它为先行词, 是因为修饰它的定语从句总是放在它之后, 先行词总是出现在定语从句之前, 而不同于普通形容词修饰名词时, 形容词位于名词之前。例句:　This is the book which I am looking for.中的book是先行词,which是引导词. 　　He is Mr. Robertson who comes from England. 中的Mr. Robertson.是先行词,who是引导词. 　　简单的说，就是和修饰宾语的词或从句，词就是先行词

先行词是被定语从句所修饰的名词、代词。在定语从句中充当一定的部分。之所以称它为先行词，是因为修饰它的定语从句总是放在它之后，先行词总是出现在定语从句之前，而不同于普通形容词修饰名词时，形容词位于名词之前。例句:This is the book which I am looking for.它是我正在寻找的书。其中的"the book"是先行词，"which"是引导词。例句:He is Mr. Robertson who comes from England.他是来自英国的罗伯森先生。其中的"Mr. Robertson"是先行词，"who"是引导词。例句:Was that a singer that sang Xi Yangyang?那个是唱喜洋洋的歌手吗?其中的"a singer"是先行词，"that"是引导词。希望对你有帮助！

先行词是被定语从句所修饰的名词、代词，在主句中充当一定的部分，没有固定的词语。例如：This is the book which I am looking for.它是我正在寻找的书。在这里“the book”就是先行词。其中定语从句分为限定性定语从句和非限定性定语从句。限定性定语从句，用来修饰和限定先行词，纯渗与先行词间的关系非常密切，它所修饰的先行词代表一个（些）或一类特写的人或物，从句用来说明先行词的搏裤做性质、身份、特征等状况，如果去掉，则意思含混不清。非限定性定语从句起补充说明作用，也不会影响全句的理解，译为汉语时常常不译作定语，而根据句意翻译为相应的其他基衡形式的从句。

先行词是一个句子时,是非限制性定语从句 1 which引导 2that有时相当于 介词+which 3有时也用 as 4 在非限制性定语从句中 不能用that ,用who whom 代表人,用which代表物.相信我,我刚学过,这是笔记上写的.加油!

That(指物)和those(指人或物)可做定语从句的先行词，this和these不可做先行词，those做定语从句先行词时，当其指物关系词用that/which等，当其指人时，关系词用who等，具体示例如下：Headmiredthosewholookedbeautiful.他很喜欢那些看上去很美的人。（指人）Headmiredthosewhichlookedbeautiful.他很喜欢那些看上去很美的东西。（指物）(错)Headmiredthatwhodancedwell.（that不能指人）(对)Headmiredthosewhodancedwell.他赞赏跳舞好的人。（those可指人）

定语从句所修饰的词 叫定语从句的先行词

可以用which,动物在整句中做宾语或主语，做宾语是which可省略，that可以引导一切关系代词适用的定语从句。

就是修饰名词和代词的从句，

先行词应该是the role in Mute Wife , for which =for the rolein Mute Wife.她由于在Mute Wife 里担任的角色而出名。

不可以。定语从句在句中做定语，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之后，由关系词（关系代词或关系副词）引出。 关系代词有：who, whom, whose, that, which等。 关系副词有：when, where, why等。而what是一个名词性代词，在句子中作主语宾语。当然不能引导了。 希望能帮到你，祝更上一层楼O(∩_∩)O有不明白的请继续追问(*^__^*)

引导定语从句的词有关系代词that、which、who、which、whose和关系副词where 、when，关系代词和关系副词是引导词，在定语从句中担当某一成份。定语从句不同于单词作定语的情况，它通常只能放在被修饰的词（即先行词）之后，定语从句由关系词（关系代词、关系副词）引导，关系代词、关系副词位于定语从句句首。定语从句的分类：根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。1、限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去，例如：Any man that/who has a sense of duty won"t do such a thing。2、非限制性定语从句主句与从句之间有逗号分开，起补充说明作用，如省去，意思仍完整，例如：The house，which we bought last month，is very nice。注意：非限定性定语从句中不能使用关系代词that。

先行词:是在定语从句中,被定语从句所修饰的名词.例如: He is a teacher who teach our English.在这里定词从句who teach our English是来修饰前面的名词teacher.所以teacher就是一个先行词. 再说下它的用法： 1、先行词指人时，引导词可用Who,Whom,及that,其中当引导词在句中作主语时用Who或that；当其充当宾语时用whom或that，在非正式宾语中也可用who，也可省略。 a That boy who/that broke the window is called Tom. b The person to whom you just talked is Mr Li. b 句可改为：The person(that/whom/who)you just talked to is Mr Li. 2、先行词指物时，引导词用that或which a.They planted the trees which didn"t need much water. b .The fish (which)we bought were not fresh. 3、先行词指时间时，引导词用When/on which或in which a.I still remember the day when/on which I first came to Bei jing. b.I"ll never forget the year when/ on which we worked on the farm. 4、先行词指地点时，引导词用Where或in which This is the house where/in which we lived last year. 或:This is the house that/which we lived in last year. 5、whose在定语从句中作定语时，可用来指人，也可以用来指物，如: a.This is the boy whose mother died a month ago. b.This is the house whose windows were broken.此句可改成： This is the house the windoues of which were broken. 6、先行词表示原因时，引导词用why,如: The reason why he was late for school was that he had been knocked down by a bike. 二、物殊情况： 尽管有以上基本原则，但要学好定语从句更应注意以下特殊情况； Ⅰ、当定语从句的先行词为表示人的不定代词，如 anyone,anybody,everyone,everybody,noone,nobody,all， these ，those等时,用who而不用that Those who break the rule are pulished. Anybody who had eyes could see the elephant was like a snake. Ⅱ.以who或which作主语的特殊疑问句中先行词指人，引导词只用That,如: a.Who is the person that is standing at the gate ? b.Which of you that knows something about English doesn"t know this word? Ⅲ、先行词指物时引导词用that而不用which的情况: 1、先行词有序数词或形容词最高级修饰时， This is the best composition that has been written in English. 2、先行词是all,something,anything,nothing,everything,little,few,much等不定代词时 There is nothing/little/much that we can do for her. 3、先行词被all,every,no,some,any,little,much等修饰时 I"ve read all the books that you gave me. 4、先行词被the only/very等修饰时 This is the very/last place that they visited yesterday. 5、有两个以上先行词，分别表示人或物时 They talked about the teachers and the schools that they had visited. 6、先行词为基数时 Yesterday I caught two fish,Now you can see the two that are still alive in a basin of water. Ⅳ.time为先行词时，前边如有序数词修饰时，定语从句引导词用that或什么也不用，如没序数词修饰时，用when或that均可 a.This is the last time(that)I shall give you a lesson. 先行词指人时，引导词可用Who,Whom,及that,其中当引导词在句中作主语时用Who或that；当其充当宾语时用whom或that，在非正式宾语中也可用who，也可省略。 a That boy who/that broke the window is called Tom. b The person to whom you just talked is Mr Li. b 句可改为：The person(that/whom/who)you just talked to is Mr Li. 2、先行词指物时，引导词用that或which a.They planted the trees which didn"t need much water. b .The fish (which)we bought were not fresh. 3、先行词指时间时，引导词用When/on which或in which a.I still remember the day when/on which I first came to Bei jing. b.I"ll never forget the year when/ on which we worked on the farm. 4、先行词指地点时，引导词用Where或in which This is the house where/in which we lived last year. 或:This is the house that/which we lived in last year. 5、whose在定语从句中作定语时，可用来指人，也可以用来指物，如: a.This is the boy whose mother died a month ago. b.This is the house whose windows were broken.此句可改成： This is the house the windoues of which were broken. 6、先行词表示原因时，引导词用why,如: The reason why he was late for school was that he had been knocked down by a bike.

先行词：先行词是被定语从句所修饰的名词、代词。在定语从句中充当一定的成分。之所以称它为先行词，是因为修饰它的定语从句总是放在它之后，先行词总是出现在定语从句之前，而不同于普通形容词修饰名词时，形容词位于名词之前。引导词：引导词是英语语法中的专有名词。引导词就是引导从句的词，比如whether，how，what，why，when等具有引导其后从句功能的词。

引导定语从句的连词不叫先行词叫关系词先行词是定语从句所修饰的词关系词分关系代词和关系副词其在定从中一定充当句子的成分只有定语从句有先行词其他从句没有先行词引导状语从句的连词叫从属连词一般不作从句中的句子成分引导名词性从句的连词叫连接词分连接词连接代词连接副词其中连接词thatifwhether不作句子成分，连接代词连接副词在名词性从句中充当句子成分广义地讲引导从句的连词都可以称为从属连词以区别于并列连词2.Theyraisedmanyquestionsasdiverseas.....，名词一般用形容词来修饰，asdiverseas中diverse就是形容词可以用来修饰questions3.Thegraphgivesinformationconcerningsales.这句话中的concerning是介词关于的意思根据该单词在字典中的定义判断4.作名词的后置修饰语与作名词的后置定语我认为一样但如果把同位语也视为修饰语的话前者包括同位语、定语。后者不包括同位语。

常见关系副词关系副词主要有三个，即when，where，why。关系副词＝介词＋关系代词。常见关系代词。限定性非限定性限定性。指人指物指物。主格who/that、which、that。宾格whom、which/that、that。属格whose of which/whose of which/whose。"先行词"与"关系词"的内在联系"先行词"与"关系词"之间实质上是互等、互换的关系。也就是说，关系词的作用就是将先行词所表达意义"代到"从句中来起作用。例如：They often become easily frightened or feel uneasy in situations（先行词）where (关系词）people normally would not be afraid .他们常在人们一般不会感到害怕的情况下却很容易感到恐惧或是感到不自在。（本句中的关系词where =先行词（in）situations。如果把这个复合句拆成两个分句，那就是：They often become easily frightened or feel uneasy in situations people normally would not be afraid in situations由此可以看出，＂先行词＂与＂关系词＂之间实质上是互等、互换的关系）。又例如：Rude people are those（先行词）whose (关系词）behavior shows little respect for the rules（先行词）that(关系词）the majority follows .不讲礼貌的人是指那些，他们的行为对大多数人所遵从的规则并不表示尊敬的人。由此我们还可以看出，＂先行词＂往往是分别重复出现在两个分句中的名词或代词。这也就是我们做定语从句的条件之必需。否则，＂关系词＂就无法去替代＂先行词＂而构筑定语从句了。这个道理就如同我们在计算机上＂做剪贴以前要先做复制＂一样。）

定语从句，是用于修饰名词或代词的一个具有完整主谓结构的句子。被修饰名词或代词在定语从句前面，称为先行词。比如who、which、where等。举例说this is a house where I live，这里where I live同样修饰前面这个house，指的是我生活的房子，那这个house同样是定语从句的先行词。总结一句话，定语从句修饰的那个名词，它出现在定语从句之前，就是先行词。那很明显先行词是名词词性：至于为什么叫先行，因为英语当中啊有一个特点，喜欢长的内容往后放，那定状都属于比较长一点的内容，尤其是从句的时候，所以呢就把它往后放，因为它又是修饰性的成分。不那么看重，所以往后放更没有什么问题了。正因为它往后放了，那被修饰的那个名词自然而然就往前挪了，这就叫先行词。

先行词是介词用什么关系代词答：先行词用的关系代词是that

先行词是名词或代词，如果名词或代词后面有修饰它们的句子且它们在句中充当某一成分，它们就是先行词。学好英语要记单词、学短语、句型要结合具体语境，不要脱离上下文孤立地死记硬背。碰到不熟悉的用法要勤于思考并不断的积累。初中生都要明白，那些英语成绩好的学生开始学英语的时候，也会出现很多的错误，但他们知道如何纠正自己的错误。

为什么要记先行词，只要你记住这个词是表示人还是物就很容易选择引导词。

who 是主格只有名词性质，例如who told you so？whose是属格和物主代词一样，有形容词和名词性质，但形式相同．例：whose umbrella is this ?<形容词性作定语>whose is this umbrella?<名词性,作表语>whom是宾格只有名词性质常用于书面语,介词之后一般用它

定语从句的引导词有关系代词who，whom，which，that，as；关系副词when，where，why;关系形容词whose。(1)This is the book which I am looking for.它是我正在寻找的书。其中的“the book”是先行词，“which”是引导词。(2)He is Mr. Robertson who comes from England.他是来自英国的罗伯森先生。其中的“Mr. Robertson”是先行词，“who”是引导词。(3)Was that a singer that sang Xi Yangyang?那个是唱喜洋洋的歌手吗？其中的“a singer”是先行词，“that”是引导词。定语从句的时态定语从句中由于涉及主句和从句，在这里也会有时态先后的问题，一般来说如果主句动词是将来时，从句用一般现在时或者一般过去时。1、从句表现一般现在时的情况A.The man who is appointed as a school principal will be a better leader.被任命为学校校长人将会是一个更好的领导者。（用is appointed不用will be appointed）。B.There will be a special regulate for somebody who takes part in the competition next week.对下周参加比赛的人将会有一个特殊的规则。（不用will take,而用takes一般现在时）。2、从句表示一般过去时的情况So to speak, those books whose covers were printed red would sale on Chrismas eve.这么说吧，那些封面被刷成红色的书将在圣诞前夕出售。（whose引导的定语从句时态为一般过去时，主句would sale为过去将来时）。

先行词是定语从句的引导词前面的名词.在定语从句中充当一定的成分.被定语从句修饰的名词、代词称为先行词。我们可以这样认为,之所以称它为先行词,是因为修饰它的定语从句总是放在它之后,先行词总是出现在定语从句之前,而不同于普通形容词修饰名词时,形容词位于名词之前。ThisisthebookwhichIamlookingfor.中的book是先行词,which是引导词.HeisMr.RobertsonwhocomesfromEngland.中的Mr.Robertson.是先行词,who是引导词.简单的说,就是和修饰宾语的词或从句,词就是先行词一、先行词与关系词A.什么是先行词被定语从句修饰的名词、代词称为先行词。我们可以这样认为,之所以称它为先行词,是因为修饰它的定语从句总是放在它之后,先行词总是出现在定语从句之前,而不同于普通形容词修饰名词时,形容词位于名词之前。Don"tforgetthebookthatItoldyoutobring.(thebook为先行词)别忘了把我让你带的书带过来。B.先行词与关系词的关系引导定语从句的词被称为关系词。关系词根据其在定语从句中的功能可分为关系代词和关系副词。关系代词在定语从句中作主语、宾语、表语、定语等,关系副词在定语从句中作状语。含有定语从句的句子一般分为两层:即主句层(第一层),定语从句层(第二层)。C.先行词与关系词的种类1.常见的关系代词2.常见的关系副词二、限定性定语从句与非限定性定语从句根据定语从句与先行词间关系的紧密程度,我们将定语从句分为限定性定语从句和非限定性定语从句。A.限定性定语从句限定性定语从句,用来修饰和限定先行词,与先行词间的关系非常密切,它所修饰的先行词代表一个(些)或一类特写的人或物,从句用来说明先行词的性质、身份、特征等状况,如果去掉,则意思含混不清。Adoctorisapersonwholooksafterpeople"shealth.(who引导的限定性定语从句,修饰先行词aperson。who在从句中作主语。)医生就是照顾病人的人。B.非限定性定语从句1.非限定性定语从句的特点非限定性定语从句起补充说明作用,也不会影响全句的理解,译为汉语时常常不译作定语,而根据句意翻译为相应的其他形式的从句。对它与主句的关系不如限定性定语从句的关系紧密,只是对先行词作些附加说明,即使去掉,主句的意思依然清楚。在非限定性定语从句的前面往往有逗号隔开,如若将非限定性定语从句放在句子中间,其前后都需要用逗号隔开。C.限定性定语从句和非限定性定语从句的区别限定性定语从句和非限定性定语从句在结构、用法及意义上差别很大。例如,Doyouknowthewriterwhowrotethenovel。whowrotethenovel修饰的词thewriter就是先行词

先行词被定语从句修饰的词

“先行词”是被定语从句所修饰的名词、代词，在主句中充当一定的部分。1、例句：ThisisthebookwhichIamlookingfor.它是我正在寻找的书。其中的“thebook”是先行词，“which”是引导词。2、例句：HeisMrRobertsonwhocomesfromEngland.他是来自英国的罗伯森先生。其中的“MrRobertson”是先行词，“who”是引导词。3、例句：WasthatasingerthatsangXiYangyang？那个是唱喜洋洋的歌手吗？其中的“asinger”是先行词，“that”是引导词。4、例句：Thefinesteloquenceisthatwhichgetsthingsdone.好的雄辩是把事情做成。其中that是先行词，which引导状语从句。

就是要修饰的那个词，一般是名词。比方IwilltellyouthenewsthatwewillgototheGreatWall.其中nes就是先行词，后面就是对先行词的补充说明。

1、先行词是被定语从句所修饰的名词、代词。先行词在定语从句中充当一定的部分。 2、之所以称它为先行词，是因为修饰它的定语从句总是放在它之后，先行词总是出现在定语从句之前，而不同于普通形容词修饰名词时，形容词位于名词之前。 3、例：Some people who are successful language learners often fail in other fields . 有些在语言学习上很有成就的人,在其他领域常常一无所成。

关于先行词定语从句所修饰、限定的词叫先行词。 作定语的句子就叫作定语从句。 定语从句通常跟在和它发生关系的先行词之后，它与先行词有着不可分割的联系。 它通常是由关系代词(who，whom， whose，that，which，as)和关系副词(where，when，why， how)来引导。 关系代词、关系副词在从句中需担当成分，但无实际意义。初中阶段我们只要理解who，that，which这几个关系代词所引导的定语从句即可。 1.关系代词who。关系代词who在从句中作主语，它的先行词是指人的名词或代词。例如： (1)Find the boy who is wearing a red shirt.找出穿红衬衫的那个男孩。(先行词是 the boy) (2)He who does not reach the Great Wall is not a true man.不到长城非好汉。(先行词是He) 2.关系代词that。关系代词that在从句中可作主语、宾语、表语。作宾语时，that可省略。它的先行词可以是指物的名词或代词，也可以是指人的名词或代词。例如： (1)She told her mother all that had happened.她把所发生的事情都告诉了她的母亲。(先行词是all，that在从句中作主语) (2)I”ll buy you the bike(that)you saw in the shop yesterday.我要给你买昨天你在商店里看到的那辆自行车。(先行词是the bike， that在从句中作宾语) (3)The village is no longer the village that it was before.这个村子不再是从前的那个村子了。(先行词是the village，that在从句中作表语) (4)He that wants to eat the fruit must climb the tree.想吃果子的就得爬树。(先行词是指人的代词he，that在从句中作主语) 3.关系代词which。关系代词 which在从句中作主语或宾语，其先行词是指物的名词或代词。例如： (1)They first went to a large room which looked like a shop.他们首先到一个很大的看起来像个商店的房间去了。(先行词是指物的名词a large room， which在句中作主语) (2)Have you got anything which you”d like to buy？你有想要买的东西吗？(先行词是指物的代词anything，which在从句中作宾语) 事实上，定语从句是一个较为复杂的语法项目。

名词 希望你们能不能帮助你

1、先行词是被定语从句所修饰的名词、代词，在主句中充当一定的部分。 2、例句：This is the book which I am looking for.它是我正在寻找的书。 其中的“the book”是先行词，“which”是引导词。

定语从句修饰的那个名词

先行词是在定语从句中,被定语从句所修饰的名词。1、例如:He is a teacher who teach our English.在这里定词从句who teach our English是来修饰前面的名词teacher，所以teacher就是一个先行词。2、例句：He is Mr. Robertson who comes from England.他是来自英国的罗伯森先生。其中的“Mr. Robertson”是先行词，“who”是引导词。扩展资料：用法：1、先行词指人时，引导词可用Who,Whom,及that,其中当引导词在句中作主语时用Who或that；当其充当宾语时用whom或that，在非正式宾语中也可用who，也可省略。That boy who/that broke the window is called Tom.打破窗户的那个男孩叫汤姆。2、先行词指物时，引导词用that或whichThey planted the trees which didn"t need much water.他们种了不需要太多水的树。3、先行词指地点时，引导词用Where或in whichThis is the house where/in which we lived last year.这是我们去年住的房子。4、先行词指时间时，引导词用When/on which或in whichI"ll never forget the year when/ on which we worked on the farm.我永远不会忘记我们在农场工作的那一年。

1. 先行词是由定语从句修饰的名词和代词，在主句中起一定的作用 2. 例句：This is the book which I am looking for.它是我正在寻找的书。其中的“the book”是先行词，“which”是引导词。
