高中英语语法系统讲解之九定语从句
语法讲座之九名词性从句和定语从句和状语从句
语法讲座之九：名词性从句和定语从句和状语从句一、名词性从句名词性从句指主语从句、宾语从句、表语从句和同位语从句。
（一）主语从句1．主语从句的引导词：wh- / that 。
例如：That he will accept the offer seems unlikely.That he always studies hard is known to us.What they are after is profit.Who will go with you hasn’t been decided yet.2. 如果主语太长或为了保持句子的平行，绝大部分主语从句用it作形式主语，将真正的主语从句放在后面。
例如：①It is + 形容词+that②It is + 名词+that③It is + 动词+thatIt is likely that it is going to rain. ①It is no use that you go there in person. ②It is known that football is played all over the world. ③(二) 宾语从句宾语从句的引导词：wh- / that 。
例如：We must find out who did all this.He told me (that) he could do it for me.He has made it clear that the meeting will not be postponed.注意：if 和whether在引导宾语从句时的特殊用法①whether or not / whether…or not 连用是固定搭配，这时，whether 不能用if来替换。
②如果宾语从句是否定句时，只能用if而不能用whether来引导。
例如：I don’t care if it doesn’t rain.I don’t care if the factory doesn’t have my pay raised.(三) 表语从句表语从句的引导词：wh- / that 。

(完整版)定语从句语法详解
定语从句语法专题（Attributive Clauses）教案一. 定语从句的概述:1.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。
在句中做定语，被修饰的名词或代词，叫做先行词。
从句通常放在先行词之后，由关系词（关系代词或关系副词）引导。
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。
eg She is the girl（who got the first prize.）girl先行词who充当从句主语, 从句做定语修饰girlThis is the boy who broke the window.这就是打破窗子的孩子。
the boy是先行词, who broke the window是限制性定语从句, 明确指出theboy是打破窗子的那个孩子,who 在从句中充当主语That is the house where he lived ten years ago.He is the man who/that lives next door.He is the man who I want to see.先行词关系词定语从句复合句: 是由一个主句和一个或一个以上的从句构成的句子, 复合句中的主句和从句都具有完整的的主语和谓语, 主句是复合句的主体, 可以独立存在, 从句需要有一个连词引导, 是修饰说明主句的, 不能独立存在, 根据在句中的不同作用, 从句可以分为三类: 定语从句, 名词性从句, 状语从句。
二. 引导定语从句的关系词有两大类:1.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: that, who, whom, whose, which, as（主, 宾, 定）关系副词: when, where, why.（状语）2.关系词的作用:（1）引导定语从句, 在先行词和定语从句之间起连接作用；（2）代替先行词在句中充当成分。

定语从句讲解(完整版)
定语从句讲解(完整版)定语从句是一种常见的语法结构，用于对名词或代词进行修饰和限定。
在英语中，定语从句的使用可以使句子更加丰富和准确。

引导词通常是先行词，即被修饰的名词或代词；关系词用于引导定语从句，并将先行词与从句连接起来；从句则是对先行词进行修饰和限定的部分。
1. 引导词：先行词通常是名词或代词，它可以是主语、宾语或表语。
例如：The book that you gave me is very interesting.（你给我的那本书很有趣。
）The man who is talking to the teacher is my father.（正在和老师交谈的那个人是我的父亲。
）2. 关系词：关系词用于引导定语从句，并将先行词与从句连接起来。

限定性定语从句通常紧跟在先行词之后，且不能用逗号与主句隔开。
例如： The book that you gave me is very interesting.（你给我的那本书很有趣。
高中英语语法知识之定语从句
定语从句1，定义：复合句中修饰名词或代词的从句，它起定语的作用。
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之后，由关系词（关系代词或关系副词）引出。
2，定语从句的分类：限定性定语从句：对其所修饰的名词来讲是必不可少的My uncle is a man who believes in discipline.非限定性定语从句：对其所修饰的名词只是一种补充说明，并不必不可少，一般用逗号隔开。
I like to chat with John, who is a clever man.3，先行词：指被定语从句修饰的名词、代词。
一般先行词出现在定语从句的前面。
4，关系词：定语从句是由关系代词和关系副词引导，前者在从句中作主语、宾语或者表语，后者在从句中作状语。
关系代词that which who whom whose as关系副词when where why5，关系词常有 3 个作用：①连接作用，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。
限制性定语从句（无逗号）一、关系代词指人who/whom/that定语从句1. The man ( who/that stands there ) is my father.分析：把 the man 代入定语从句中是充当主语，即：The man stands there ,所以连接词可用who 和 that例句： The beautiful girl who/that wears blue coat is my girl.2. The man （whom/who/that they are talking about） is my father.分析：把 the man 代入定语从句中是充当宾语，即：They are talking about the man ,所以连接词可用who, that和whom, 也就是说whom只能是当先行词代入定语从句中充当宾语的时候才可用。
高中英语语法知识总结：定语从句
高中英语语法知识总结：定语从句下面就是小编给大家带来的高中英语语法知识总结：定语从句，希望能帮助到大家!高中英语语法知识总结：定语从句易错点1 关系代词与关系副词的混用1.定语从句相当于一个形容词，起定词作用，修饰名词或代词2.定语从句的引导词的三种功用:( 1)引导定语从句(2)替代先行词(3)在定语从句中充当一定的成分。
3.解题要领:根据定语从句中所缺成分来确定是用关系代词还是关系副词，决不要因先行词是时间名词就用when，是地点名词就用where。
易错点2 关系代词who、whom、whose的误用对于定语从句关系词的考查，首先要确定从句是什么类型的从句，然后再分析关系词在从句中的成分，最后选择正确的词。
要求考生具有一定的句子分析能力，和理解能力。
如果缺少主宾表，要用that或which，缺少状语用关系副词when，where，why，缺少定语用whose。
易错点3 关系代词that和which的误用只用which，不能用that的情况(1) 在介词提前到关系代词之前形成"介词+关系代词"结构来修饰表事物的先行词时，关系代词必须用which.如：☞The house in which we live is very large. 我们住的房子非常大。
这就是老师正在谈及的那本参考书。
注意：如果介词不放在修饰事物的限定性定语从句的句首，which就可换为that，如：☞This is the question which/that we’ve had so much discussion about. =This is the question about which we’ve had so much discussion. 这就是我们已经多次讨论过的问题。
(2) 先行词为"those+表事物的复数名词"时，关系代词通常只用which而不用that。
如：☞Students should keep in mind those regulations which restrict their behavior.学生应牢记那些规范自己的行为准则。

高中英语语法系统讲解之九定语从句定语从句在复合句中修饰一个名词或代词。
被定语从句修饰的名词或代词叫做“先行词”。
引导定语从句并作定语从句中的一个成分的词叫做“关系词”。
常见的关系词有关系代词（who，whom，whose，that，which等）和关系副词（when，where，why等）。
关系词有两个作用：1、放在先行词与定语从句中间起连接作用，引导定语从句；2、代替先行词在其引导的定语从句中充当一定的句子成分，并与先行词保持数的一致。
关系代词引导的定语从句1、关系代词及其作用一览表2、关系代词特殊用法一览表温馨提示：“whose + 名词”这一结构在定语从句中既能作主语，又能作宾语，whose的先行词常用来指人，但有时也可以用来指具体事物或抽象概念，这时可以与of which结构互换，词序是“the+名词 + of which”。
如Please pass me the book whose cover (the cover of which) is green.3. 关系副词的用法○1由when引导：when指时间，在从句中作时间状语，它所修饰的先行词有time，day，morning，night，week，year等。
如From the time when he was little, he had known what he wanted to be when he grew up.○2由where引导：where指地点，在从句中作地点状语，它的先行词有place，spot，street，room，city，country等。
如Is this the room where you were living last winter?Beijing is the place where I was born.○3由why引导：why表示原因，常用在先行词reason后面。
如The reason why he said that is quite clear.I don’t know the reason why she looks unhappy today.4. 使用关系副词时应注意的几点：○1有些先行词虽不表具体的地点，但表达一种“阶段、境地、形势、地步”，也可用where来引导定语从句。
如：stage，situation，case，point等。
如：At that time we had reached a stage where we had more women readers than men readers.Increasing poverty has led to a situation where some people cannot afford their children’s school fees.Can you think of a case where you are mistaken by others, but you can’t tell the truth?It seems that their relation has reached the point where they have to divorce.○2先行词虽然是表示时间、地点或原因的名词，但如果关系词在从句中作主语或宾语，则用关系代词that或which引导。
对比：I will never forget the happy days which we spent we spent together.I will never forget the days when we visited your university. This is the special school which was set up 10 years ago. This is the special school where my father has taught for 10 years.Do you believe the reason that he gave?Do you know the reason why he killed himself?○3在某些表示时间名词后的关系副词可省略。
如the time，every time，each time，the moment。
如Do you still remember the day (when) we first met?5. “介词 + 关系代词”引导的定语从句○1“介词 + 关系代词”引导的定语从句中的关系代词只能用which或whom。
先行词表物时用which；先行词表人时用whom。
介词的使用取决于句子意义的需要，或句中动词、形容词、副词与介词的搭配，表“所有”关系或“整体中的一部分”时，用of。
如：I don’t know the time at which(= when) the meeting will begin.I still remember the day on which(= when) I first came to thisschool.This is the subject about which we might argue for a long time. This is the worker from whom I have learned a great deal.Is that the boss to whom you have explained your situation?I bought a dozen of eggs, half of which were broken when I gothome.○2当介词位于定语从句的末尾时，可用that / which（指物），that / whom / who（指人）作介词的宾语，而且作介词宾语的关系代词往往省略。
如This is the hero (that / who / whom) we are proud of.This is the pen (that / which) I wrote the letter with.○3“复合介词短语 + 关系代词which”引导的定语从句，这种结构引导的定语从句常与先行词用逗号分开，定语从句常用倒装语序。
如He lived in a big house, in front of which stood a big tall tree.○4介词 + 关系代词 = 关系副词。
如This is the room which we lived in last year.This is the room in which we lived last year.This is the room where we lived last year.6. 关系代词as引导的定语从句○1 as用作关系代词，引导限制性定语从句，常可与主句中的the same或such 相呼应，其中as为代词，在从句中作主语、宾语、表语。
如We do the same work as they (do).He is not the same man as he was.I hope to get such a dictionary as he is using.We will give you such information as will help you in your work. ○2 as引导非限制性定语从句，在句中作主语、宾语或表语，这个定语从句是说明整个句子的，它可以放在主句之前。
如As we all know, he studies very hard.As is known to all, he is the best student in our class.常用的这种类似插入语的句式有as is said above，as it is等。
7. 限制性定语从句和非限制性定语从句限制性定语从句是整个句子不可缺少的部分，主句和从句之间不用逗号分开，其引导词可用关系代词that，which，who，whom，whose，as和关系副词when，where，why。
这些引导词一般只在从句中作宾语时才可省略。
非限制性定语从句是对主句先行词的补充说明，没有从句，也不影响主句意思的完整。
一般不用逗号把主句和从句分开，通常不用关系代词that。
如A dictionary is a book which gives the meaning of words.I have lost a pen, which I like very much.Do you remember the teacher who taught us Chinese at middle school?I have two brothers, who are both students.温馨提示：○1as和which引导非限制性定语从句时，都可以指代整个主句内容，二者的区别是： as引导的定语从句位置灵活，可放在句首、句中或句末；which引导的定语从句只能放在主句之后；as意为“正如；这一点”；which意为“这件事”。
如As is mentioned above, English is easy to learn.He failed in the examination again, which disappointed his parents. ○2、非限制性定语从句通常不用that引导。
I am fond of the novel, which you bought for me.○3、在非限制性定语从句中，指人的关系代词作宾语时，只能用whom，不能用who替换，也不能省略。
Lily, whom you met at the party, is my favorite friend.○4、非限制性定语从句不能用why引导，要用for which代替why。
eg: I have told him the reason, for which I missed the early bus.8. 使用定语从句应注意的问题○1关系代词在从句中作主语时，从句的谓语动词用单数还是复数应由先行词决定。
如The man who lives downstairs speaks English fluently.The students who are in Grade Three are going to climb the hill tomorrow.○2引导定语从句的关系副词可以用“介词 + which”代替。
