定语从句引导词及用法
定语从句引导词及⽤法 定语从句中会有引导词，那么定语从句引导词有哪⼀些呢?以及他们的⽤法⼜是什么呢? 1. 关系代词有：that,which,who,whom,whose,在定语从句中作主语、宾语中表语，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) Im 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：Well 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) 定语从句引导词及⽤法 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。
who, whom, whose, that引导的先行词指人的定语从句
who，whom，whose和that作为定语从句的引导词，称为关系代词。
我们现在来看一下先行词指人时，这四个关系代词的使用问题。
下面用句子合并的方法来分析。
一、定语从句用who或that做引导词，在从句中做主语。
把句②变为句①的定语从句，句①中的the boy做定语从句的先行词。
在句②中he指句①中提到的the boy也就是定语从句的先行词，he在句中做主语，因此要用who和that引导定语从句，代替句②中的he，也就是说he就不能出现在定语从句中了。
由此得到句③The boy who broke the window is called Jack.注意：一般情况下定语从句要紧挨先行词。
请把下面每组的两句话合并为一句。
The person must pay for it. / He lost the library book.→The person who lost the library book must pay for it.The boy is very clever. / He is wearing the black jacket.→The boy who is wearing the black jacket is very clever.二、定语从句用who，whom或that做引导词，在从句中做宾语。
因为是做宾语，所以这些引导词可以省略。
请分析下面两个简单句：句①Do you know the young man？句②We met him at the gate.把句②变为句①的定语从句，句①中的the young man做定语从句的先行词。
在句②中him指句①中提到的the young man也就是定语从句的先行词，him在句中做宾语，因此要用whom，that或who引导定语从句，代替句②中的him，也就是说him就不能出现在定语从句中了。
由此得到句③Do you know the young man who/that/whom we met at the gate？(who/that/whom可以省略，句子可以写作：Do you know the young man we met at the gate？)请把下面每组的两句话合并为一句。

例:Hands up, anyone who knows the answer.知道答案的请举手。
All who / that heard the story were amazed.听到这个故事的人都感到吃惊。

who, which引导的定语从句
who, which引导的定语从句在复合句中，修饰某一名词或代词的从句叫定语从句。
它的作用相当于一个形容词。
定语从句通常位于它所修饰的名词或代词之后，这一名词或代词叫先行词，引导定语从句的关联词为关系代词（副词）。
这里主要介绍关系代词who与which的用法。
关系代词who（whom）和which均可引导定语从句，who用来指人，而which指物，在从句中充当主语或宾语。
请看例句：We shall never forget Mr Li who taught us English in the middle school. 我们永远不会忘记中学时教我们英语的李老师。
(who在从句中作主语)The man who(m) you saw last week has left the town. 上周你看见的那个人已离开这个城镇了。
（whom也可用who, 在从句中作saw的宾语）【温馨提示】关系代词在从句中作宾语时，常可省略。

（which在从句中作主语）This is a reason which we must not forget. 这是我们不能忘记的一个原因。

但在下列情况中，通常用which, 不用that。
当先行词有指示代词修饰时。
如：The lady did not want that one which smelt terrible. 那位夫人不要气味难闻的那个。
当关系代词前有介词时。
如：The room in which my family live used to be a garage.我家住的房间以前是个车库。
定语从句的关系代词
定语从句的关系代词在复合句中修饰某个名词或代词的从句叫做定语从句。
学习定语从句，引导定语从句的关系代词有who, whom, whose(一般指人);which(一般指物); that(指人或物)等。
在句中充当主语、宾语、表语或定语。

(关系代词who / that 作主语。

)关系代词引导定语从句要注意下列几个问题：一、关系代词与先行词。
关系代词所修饰的(或指代的)词叫做先行词;先行词如果是“物”，则关系代词用which或that; 先行词如果是“人”，则关系代词用who或that; 也就是说，that 既可用来修饰“人”也可用来修饰“物”。
如：1. This is the newspaper which / that I am looking for.[分析]定语从句的先行词为news-paper, 故关系代词可以用which或that。
2. Mr. Li is the teacher who/that teaches us English.[分析]定语从句的先行词为teacher, 故关系代词可以用who或that。
定语从句THAT和WHO

但在以下情况用who。
1.当先行词是persons, people, those时。
例如：Those who are for my plan , please put up your hands.同意我的计划的人请举手。

引导定语从句的关系代词who,which有时可与that互换使用。

如： a.Which is the book that he bought yesterday? b.Who that you have ever seen can beat him in定语从句是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个名次性成分，定语从句分为限定性和非限定性从句两种。
一、限定性定语从句1. that即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在从句中作宾语则不能省略。
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all, anything, much等，这时的that常被省略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. where是关系副词，用来表示地点的定语从句6. 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 besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.7. 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8 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来引导二、非限定性定语从句：非限定性定语从句的作用是对所修饰的成分作进一步说明，通常和主句间用逗号隔开，将从句拿掉后其他部分仍可成立1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分2. 在引导限定性定语从句时，that有时相当于in which, at which, for which或at which Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处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We arrived the day that(on which) they left. 刚好我们到的那天他们走了。
3有时as也可用作关系代词4在非限定性定语从句中，不能用that，而用who, whom代表人，用which代表事物.一.定语从句及相关术语1.定语从句：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面。
2.关系词：引导定语从句的关联词成为关系词（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；关系副词有where, when, why等）关系词常有3个作用：1，引导定语从句。
2，代替先行词。
3，在定语从句中担当一个成分。
二.关系代词引导的定语从句1.who指人，在从句中做主语The boys who are playing football are from Class One.2.whom指人，在定语从句中充当宾语，常可省略Mr. Liu is the person (whom) you talked about on the bus（注意：关系代词whom在口语和非正式语体中常用who代替，可省略）3.which指物，在定语从句中做主语或者宾语，做宾语时可省略Football is a game which is liked by most boys4.that指人时，相当于who或者whom；指物时，相当于which。
在宾语从句中做主语或者宾语，做宾语时可省略The number of the people that/who come to visit the city each year rises one million.5.whose通常指人，也可指物，在定语从句中做定语He has a friend whose father is a doctor.三.介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时，从句常由介词+关系代词引导The school (that/which) he once studied in is very famous注意：1. 含有介词的动词短语一般不拆开使用，如：look for, look after, take care of等1)This is the watch which/that I am looking for. (T)2)This is the watch for which I am looking. (F)2. 若介词放在关系代词前，关系代词指人时用whom，不可用who或者that；指物时用which，不能用that；关系代词是所有格时用whoseThe man with whom you talked is my friend. (T)The man who/that you talked with is my friend. (F)3. “介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词(1) He loved his parents deeply, both of whom are very kind to him.四．关系副词引导的定语从句1. when指时间，在定语从句中做时间状语The time when we got together finally came2. where指地点，在定语从句中做地点状语Shanghai is the city where I was born3. why指原因，在定语从句中做原因状语Please tell me the reason why you missed the plane（意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换）The reason why/ for which he refused the invitation is not clear,From the year when/in which he was going to school he began to know what he wanted when he grew up限制性定语从句举例The teacher told me that Tom was the only person that I could depend on.非限制性定语从句举例：His mother, who loves him very much, is strict with him.区分定语从句和同位语从句1．定语从句修饰先行词，它和先行词是修饰关系；同位语从句说明先行词的具体内容，是补充说明的关系1)The plane that has just taken off is for London. 定语从句2)The fact that he has been dead is clear. 同位于从句2．定语从句由关系代词或者关系副词引导，关系词在句中充当成分，有时可以省略；同位语从句主要由that引导，在句中一般不做成分；句子也可以由when, where, how, why, whether, what等词引导，充当成分The problem that we are facing now is how we can collect so much money. 定语3. 同位语从句和先行词一般可以用be动词发展成一个完整的句子，而定语从句不可以The idea that we could ask the teacher for advice is wonderful. 同位语。
