英语定语从句用法总结(完整)
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。
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；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。
注：关系代词有主语、宾语之分。
一般 whom 作为宾语。
定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语(动词不定式短语、动名词短语和分词短语)或句子，汉语中常用表示。
主要由形容词担任，此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任。
单词作定语时通常放在它所修饰的词之前，作前置定语。
短语和从句作定语时则放在所修饰的词之后，作后置定语。
被定语从句修饰的名词、代词称为先行词。
关系代词所代替的先行词是人或物的名词或代词，并在从句中充当主语、宾语、定语等成分。
关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
这些词代替的先行词是人的名词或代词， who 做主语指人， whom 作宾语指人，that 既可作主语又可作宾语(作宾语可以省略)，可以指人也可以指物。
在从句中所起作用如下：(1) Is he the man who/that wants to see you? 他就是想见你的人吗？ ( who/ that 在从句中作主语)(2) He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。
( w hom/that 在从句中作宾语)(1) They rushed over to help the man whose car had broken down. 那人车坏了，大家都跑过去帮忙。

定语从句与名词性从句
定语从句与名词性从句定语从句与名词性从句是汉语中常用的两种从句结构。
它们在修饰与引导句子中起到关键的作用，并且丰富了句子的表达方式。
本文将详细介绍定语从句与名词性从句的用法、特点及示例。
一、定语从句定语从句是用来修饰名词或代词的从句，它通常由关系代词或关系副词引导。

作宾语时可省略。
I have an apple which is red. This is the place that(which) we visited last time.I have an apple that is green. He is still the boy that he was ten years ago.主句为完整的句子时大多用关系副词，WHEN WHERE WHY主句不完整时用关系代词代指人的有 who whom that代指物的有 which that 表…………的时用 whose1、who, which, that限定性定语从句中的关系代词可理解为必要从句。
The first English book that I read was "The Prince and the Pauper" by Mark Twain. 我读的第一本书是马克·吐温写的《王子与贫儿》。
(4)先行词既有人又有物时;He talked about the teachers and school that he visited. 他在讲他以前访问过的学校和老师。
(5)当主句是以who或which开始的特殊疑问句时，为避免重复用that;Who is the person that is standing at the gate? 那个站在门口的人是谁?(6)关系代词在从句中作表语时;He is not the man that he used to be. 他以前不是这样的人。
注:which在定语从句中指物，可作主语、及物动词或介词的宾语，作宾语时可省略;that在定语从句中既可指人又可指物，在定语从句中作主语、宾语或表语，作宾语时可省略。
定语从句的种类
定语从句的种类定语从句的种类引导语：从句是相对于主句而言的,即它是从属于某一个主句,而不能单独作一个句子.在中,主要有三大从句,即名词性从句（包括主语从句,宾语从句,表语从句,同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）.主语从句用作主语,如：That the earth is round is true.地球为圆的是真实的.宾语从句用作宾语.如：Do you know where he lives?表语从句用作表语,如：My opinion is that you should not go alone.我的意见是你不应单独前往.同位语从句用于解释说明前面的名词.如：The fact that the earth is round is true.地球是圆的的事实是真实的.（that从句用于解释说明the fact）定语从句相当于一个形容词,用于修饰前面的名词.如：The student who answered the question was John.回答问题的学生是John.状语从句相当于一个副词,如：When it rains,I usually go to school by bus.天下时,我通常坐公共汽车上学.（时间状语）If he comes tomorrow,you will see him.如果他明天来,你就可以看见他.（if 引导的条件状语从句,其结构为：if +状语从句,＋主句）.要注意在状语从句中有一个规则是“主将从现”,即主句是将来时,则从句要用一般现在时表示将来.主句和从句的划分方法是相同的.句子的成分从谓语动词处来划分比较容易.谓语动词前面的部分是主语,后面常接宾语,修饰谓语动词的是状语,修饰主语、宾语的是定语,若谓语是系动词,则系动词后的部分是表语.如：I am a teacher.其中,I 是主语,am是谓语,a teacher 是表语.He likes playing football very mucy.其中,he是主语,likes是谓语,playing football是宾语,very much是状语.英语中8种从句介绍1定语从句2时间状语从句3地点状语从句4条件状语从句5同位语从句6表语从句7宾语从句8主语从句名词性从句：在句子中起名词作用的句子叫名词从句(Noun Clauses）.名词从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,因此根据它在句中不同的语能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句.引导名词性从句的`连接词引导名词性从句的连接词可分为三类：连接词：that,whether,if 不充当从句的任何成分）连接代词：what,whatever,who,whoever,whom,whose,which.连接副词：when,where,how,why不可省略的连词：1.介词后的连词2.引导主语从句和同位语从句的连词不可省略.That she was chosen made us very happy.We heard the news that our team had won.比较：whether与if 均为"是否"的意思.但在下列情况下,whether不能被if 取代：1.whether引导主语从句并在句首2.引导表语从句3.whether从句作介词宾语4.从句后有"or not"Whether he will come is not clear.大部分连接词引导的主语从句都可以置于句末,用 it充当形式主语.It is not important who will go.It is still unknown which team will win the match.由从属连词that引导的从句叫做名词性that-从句.That只起连接主句和从句的作用,在从句中不担任任何成分,本身也没有词义.名词性that-从句在句中能充当主语、宾语、表语、同位语和形容词宾语,例如：主语：That he is still alive is sheer luck.他还活着全靠运气.宾语：John said that he was leaving for London on Wednesday.约翰说他星期三要到伦敦去.表语：The fact is that he has not been seen recently.事实是近来谁也没有见过他.同位语：The fact that he has not been seen recently disturbs everyone in his office.近来谁也没有见过他,这一事实令办公室所有的人不安.形容词宾语：I am glad that you are satisfied with your job.你对工作满意我感到很高兴.2）That- 从句作主语通常用it作先行词,而将that-从句置于句末,例如：It is quite clear that the whole project is doomed to failure.很清楚,整个计划注定要失败.It's a pity that you should have to leave.你非走不可真是件憾事【定语从句的种类】。

定语从句的八种类型
定语从句的八种类型定语从句的八种类型：which引导的非限制性定语从句；as引导的非限制性定语从句；由“介词＋关系代词”引导的定语从句；由where，when，why引导的定语从句；•由where，when，why引导的定语从句；由whose引导的定语从句；分隔式定语从句以及关系词省略的限制性定语从句。
第一种类型：which引导的非限制性定语从句which指代整个主句的内容，它引导的定语从句一般位于主句的后面，它的意思是“这(那)件事……”，在这些从句中which作主语或宾语。
第二种类型：as引导的非限制性定语从句as也可指代整个主句的内容，但不同于which的是，它引导的定语从句既可以位于主句的前面，也可以位于主句的后面。
它的意思是“正如”，在这些从句中as作主语或宾语。
第三种类型：由“介词＋关系代词”引导的定语从句用于这种情况的关系代词一般为which(指物)和whom(指人)。
在这种结构中，介词的选择非常关键，可以遵循以下四个原则：(1)根据定语从句中的谓语动词确定介词，其动词与介词搭配，构成动词短语。
(2)根据定语从句中的形容词确定介词，其形容词与介词搭配，构成形容词短语。
(3)根据定语从句修饰的先行词确定介词，其先行词往往是表示时间、地点、原因、方法、工具等的词，它们与介词之间有一定的联系。
当“介词＋关系代词”在定语从句中充当时间、地点、原因状语时，可分别用when,where,why替换。
(4)根据句子的意思确定介词。
有些句子，先行词完全一样，定语从句中谓语动词不是由固定的动词短语构成的，这时，要根据句子所要表达的意思，选用不同的介词。
第四种类型：由where,when,why引导的定语从句关系副词where,when,why引导定语从句时，它们分别在从句中充当地点时间、原因状语。
第五种类型：whose引导的定语从句此时要注意三点：(1)whose引导的定语从句，其后应紧跟名词，构成“whose+名词”；(2)whose引导的定语从句，其先行词不仅可以指人，还可以指物；(3)whose引导的定语从句指物时，可用of which代替whose，但词序不同，即whose+名词=the+名词+of which。
定语从句—搜狗百科
定语从句—搜狗百科⼀、先⾏词和关系词1）Whoever spits in public will be punished here.（“Whoever”可以⽤“anyone who”代替）2）The parents will use what they have to send their son to technical school. （“what”可以⽤“all that”代替）但这两句句⼦已经不是定语从句了，是名词性从句。
因为定语从句⼀定要有先⾏词，⽽名词性从句没有。
将“Whoever”、“what”分别⽤“Anyone who”、“all that”代替后，才是定语从句，先⾏词分别是“Anyone”、“all”。
Alice received an invitation from her boss,______ came as a surprise.A. itB. thatC. whichD. he答案C。
a选项it，使前后成为两个句⼦，中间⽆连词连接，语法错误；b项that，此为⾮限定性从句，不能⽤“that”修饰；c选项which，which在从句中做主语，⽤来代指前⾯的这件事；d选项he；前半句中是her boss，所以不正确。
2）The weather turned out to be very good, ___ was more than we could expect.A. whatB. whichC. thatD. it答案BA选项不能⽤来引导定语从句，C选项只能引导限定性定语从句，⽽D选项习惯上并不适⽤。
3）It rained hard yesterday, ____ prevented me from going to the park.A. thatB. whichC. asD. it答案B“as”和“which”在引导⾮限宾语。
但不同之处主要有两点：（1）importance to me, as my own is.在⼀定的语⾔环境⾥，有些名词可以具有形容词的性质。
同位语从句与定语从句的相似点
一.同位语从句与定语从句的相似点1．同位语从句与定语从句都可以译成定语同位语从句：The news that our team has won the finalmatchis encour aging.我们队取得决赛胜利的消息令人鼓舞。
定语从句：The news that you told us is really encour aging.你告诉我们的消息真的令人鼓舞。
2．同位语从句与定语从句都可以用th at引导同位语从句：The sugges tionthat studen ts should learnsometh ing practi cal is worthconsid ering.学生应该学些实用的东西的建议值得考虑。
定语从句：The sugges tionthat is worthconsid ering is that the studen ts should learnsometh ing practi cal.值得考虑的建议是学生应该学些实用的东西。
3.同位语从句与定语从句和其它名词性从句一样也要用陈述语序同位语从句：Have you any idea wherehave they gone？ (语序错误)Have you any idea wherethey have gone？你知道他们去哪里了吗？定语从句：Do you rememb er the day when did you join our club?（语序错误）Do you rememb er the day when you joined our club?你记得自己什么时候参加我们俱乐部的吗二.同位语从句的独特用法虽然同位语从句与定语从句有以上相似之处，但是有些用法是同位语从句独有的，不能用于定语从句。
定语从句口诀
定语从句口诀定语从句口诀定语从句口诀：which指物who指人，whom、which介后陈。
that/only序all最，不定代词物与人。
that不用有逗号，介词提前更无份。
介宾不省动宾省，须做成分从句真。
定语从句口诀解释：“which指物who指人”，就是在引导定语从句时，如果先行词（被定语从句所修饰的那个名词）是物或者事情，就用which来引导(当然用that也行)，而如果先行词是人，就用who来引导(当然用that 也行)。
如：This is the bookwhichmy father bought last year.这就是我爸爸去年买的那本书。
which指物，即前面的the book,当然，that也行。
I still remember the boywhooften helps the old man.我还记得那个经常帮助那位老人的男孩。
who指前面的先行词the boy，当然，用that也行。
“whom、which介后陈”，就是当引导词做定语从句中介词的宾语、并且介词又提到了引导词的前面时，就只能用whom或which 来引导了。
如：The bookwhich/thatwe talkedaboutis new.我们谈论的那本书是新书。
在这个句子中，which或that指代的'是前面的the book,又同时作介词about的宾语，在介词about没有提前的情况下，which或that作从句中介词about的宾语是可以的。
The bookabout whichwe talked is new.我们谈论的那本书是新书。
此句中的介词about被提到了引导词which的前面，这时规定不可以再用that引导了，即“介词提前更无份”。
We all like the teacherwho/whom/thatwe learn a lotfrom.我们都喜欢我们从那里学到了很多知识的那名老师。

定语从句一、定语从句的定义和结构在复合句中修饰某一名词或代词，充当定语的从句。
被修饰的词叫先行词，引出从句的词叫关系词（分关系代词和关系副词）。
定语从句可分为限制性定语从句和非限制性定语从句两种。
引导定语从句的词有关系代词that, which, who (宾格whom,所有格whose),as, but, 和关系副词where , when , why。
关系词放在先行词和定语从句之间起连接作用，同时又指代先行词内容，并在从句中充当一个成分。
关系词是根据先行词类别、关系词在从句中所作成分以及其他特殊要求三个方面确定的。
关系词基本分类：指人：who, whom, whose, of whom, that, as, / 指事物：which, whose, of which, that, as,指人或事物：whose, that, as, /指时间：when 指地点：where 指原因：why二、关系代词引导的定语从句关系代词：that, which, who, whom, whose, (as, but).1) that的先行词可指人或物，以及人与物同指。
that在从句中作主、宾或表语：I like the book that you lent to me.The boy that is standing near the door is my brother.He is no longer the person that he used to be.2) which的先行词是物。
which在作从句的主语或宾语：They planted the flowers which didn't need much water.The dictionary which my father bought for me is very useful to me.我爸爸给我买的词典非常有用。
指物时有时可互换（二者的区别见“定语从句注意事项”）。
3) who/whom的先行词是人。
在从句中作主语用who，作宾语用whom。
The teacher who went to see me yesterday is Mr. Wang.The girl whom I talked with just now will go to Beijing.Mr. Read is the person to whom you should write.4）whose的先行词可以是人也可是物。
whose在从句中作定语。
whose可用of which, of whom换用，不过of which和of whom除了表所属外还可以表示部分与整体的关系。
He is the boy whose father is a doctor.Do you know the owner of the house whose windows / the windows of which / of which the windows face south?Here are ten players, three of whom are from London.All the books, five of which are broken, have been put away.whose还可以与它修饰的词一起作介词宾语：The boss in whose department Mr. King worked called at the hospital.①He studies in a school whose buildings(= ) are built on top of a hill.②Recently I bought an ancient Chinese vase, _______ was very reasonable.A. which priceB. the price of whichC. its priceD. the price of whose三、关系副词引导的定语从句关系副词：why, where, when（非正式用法中都可用that代替）。
它们也可用介词 + which代替，关系副词在从句中都作状语。
1)why(=for which)的先行词只用the reason。
why在从句中作原因状语。
I don't know the reason why (for which) he didn't come.★当先行词为reason时，关系词若不在从句中作状语，就只能用that或which，而不是why。
①The reason he didn't attend the meeting was that he was ill.②Can you tell me the reason you didn’t finish your homework?③I don't believe the reason he gave me.④Have you asked him the reason may explain his success?比较⑤He was late .That's because he got up late.// ⑥He got up late. That's why he was late.2) where（=介词+ which）的先行词是表地点的词，如：house, room, place等。
where 在从句中作地点状语。
This is the school where we study every year.★当先行词为地点名词时，关系词若不在从句中作状语，就只能用that或which，而不是where。
This is the school which we study in every day.This is the school that / which we visited yesterday.①This is the factory they worked last year.②This is the factory they visited last year.③I think you have got to the point a change is needed, or you would fail.④He's got himself into a dangerous situation he's likely to lose control of the plane.3) when（=介词+ which）的先行词是表示时间的名词，如time, year, day, week等。
when在从句中作时间状语。
I'll never forget the time when (during which) we worked on the farm.★当先行词为时间名词时，关系词若不在从句中作状语，就只能用that或which，而不是when。
I still remember the day that / which is his birthday.①Next month, you will be in your hometown, is just around the corner.②There are occasions joking is not permissible.③I still remember the days we lived together.④I still remember the days we spent together.四、限制性定语从句和非限制性定语从句1)限制性定语从句是对先行词作修饰或限制，缺少从句时句子意义不完整或失去意义。
主从句关系十分密切，所以书写时不用逗号分开。
He is the man who came to see youyesterday.2)非限制性定语从句只是对先行词作些附加说明，主从句关系不十分密切，所以从句和主句之间多用逗号分开，若去掉从句，主句的意思仍然清楚。
一般用which引导，不用that。
My brother, who is in Beijing, will come to see me.（非限制性）The book that/which you are reading is mine.（限制性）五、关系代词as引导的定语从句1)引导限制性定语从句时用于固定搭配：as/so/such/ the same+先行词+as从句You can wait for me at the same place as we did.Beijing is not the same (city) as it used to be.从句：表示同一人或物the same ···as从句：表示相似的人或物This is the same knife that I lost .这是我弄丢的那把刀。
This is the same knife as I lost.这把刀与我弄丢的那把刀一样。
such ...that...状语从句：“如此…以致于…”We need such material as is being used in your factory.（定语从句）This is such an easy question as I can answer.（定语从句）This is such an easy question that I can answer it.（状语从句）2) as与which引导非限制性定语从句的区别与which引导非限制性定语从句相比：①as的先行词一般不是一个单词，常是整个主句或短语；which的先行词可以是一个单词或整个主句；②as通常含有“正如...那样”的意思，而which没有；③as从句可放在句首/中/尾，而which从句不能放在句首；④as在从句中作主语时谓语中一般必须含be动词，which没有此限制。
⑤which从句可表由主句带来的结果，as从句不能。
如：As we have seen, the earth is round. /As we know, Tai Wan belongs to China. As is reported, many people were killed in the accident.The earth is round, as we all know.正如大家所知,地球是圆的。
