三介词提前的定语从句（介词+关系代词+……）1 关系代词which, whom在定语从句中作介词的宾语时，从句可有：介词+ which\whom 引出。
如：1）Great changes are taking place in the city which they live in .Great changes are taking place in the city in which they live.2) The film which I’m speaking of is to be shown next week.The film of which I’m speaking is to be shown next week.3.

二当堂训练1 用关系副词when, where 把下列每对句子连接成定语从句。
1）I’ll never forget the day. I joined the PLA on that day._________________________________________________.2) Last autumn my sister went to the town. She was born there._____________________________________________________.3) The days are gone. During those days we used ‘foreign oil.”___________________________________________.4) Li Fang lives in that street. Do you know the street?______________________________________________________?二如何判断关系代词与关系副词1. 用关系代词，还是关系副词完全取决于从句中的谓语动词。
及物动词后无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。
如：This is the mountain village where I stayed last year (stay 是不及物动词)This is the mountain village which I visited last year.(visit 是及物动词)This is the house which I bought last year.(buy是及物动词)This is the house where I lived last year.(live 是不及物动词)I will always remember the days when we worked together.(work 是不及物动词)I will always remember the days which we spent together. （spent 是及物动词）Ancient China was a place where states were often at war with each other.It was also a time when there were many great philosophers.2. 当堂训练：填空1. Is this museum _______ you visited a few days ago?2. Is this museum _____ the exhibition was held.3. It is the school _______ the film star studied when she was young .4 It is the school ________ I hated when I was young.5. It is an important day ______ I’ll never foget.6. It is an important day ______I first gave a speech in public .7. The hotel _____ they are staying is very expensive.8 The hotel ______ they bought is very expensive.三当堂检测1 The house ______ we live is not large.A. whichB. whereC. thatD. what2. The hotel _______ they are staying is very expensive.A. of whichB. at thatC. thatD. at which3. He’s got himself into a dangerous situation________ he i s likely to lose control over the plane.A. WhereB. whichC. whatD. why4 Do you know the reason ______ he was late for the meeting?A. whereB.whyC. whenD. that5. The hotel _______ your father is working is the most expensive in the city.A. thatB. whereC. of whichD. \6 The small town is just the one ______ the famous film star was born.A. whichB. whereC. thatD. \定语从句之非限制性定语从句1定语从句有时跟先行词的关系并不十分密切，只是作一些附加说明，不起限制作用，这种从句称为非限制性定语从句。
这类从句往往用逗号和主句分开。
且不能用that 引导。
如：1）Mr zhang, who came to see me yesterday, is an old friend of my father’s .2.）We walked down the village street, where they were having market day .3.）Football , which is a very interesting game, is played all over the world.4 ）The person , to whom I was speaking , is my English teacher.5 ）Sun Yat-sen, who was the leader of the 1911 Revolution, first suggested the idea of a damacross the Yangtze River in 1919.6）. The Empire Sate Building, which was the tallest building at the time was finished in May 1931.2. 有时这类定语从句所修饰的不是前面某一个词，而是代表整个主句所讲的内容，通常用逗号和主句分开。
如；1）He gave his mother a Tv for her birthday, which made her happy.2) He is coming back to us, which means that he has been refused elsewhere.3）Alice did’t get the job, which made her upset.他要回到我们这儿了，这意味着他在别处遭到了拒绝。
定语从句中介词+关系词
“介词+关系词”的用法1、关系代词在从句中作介词的宾语时，介词常可以提前,但介词提前时,关系代词只能用which 或whom.如:The school （that/which) he once studied in is very famous.→The school in which he once studied is very famous。
Tomorrow I will bring here a magazine （that/which）you asked for.→Tomorrow I will bring here a magazine for which you asked。
We’ll go to hear the famous singer (whom/that/who）we have often talked about。
→We’ll go to hear the famous singer about whom we have often talked.2、关系副词when, where, why 和介词+which之间的关系。
关系副词when, where，why可以用适当的介词+which来替代。
介词的位置非常灵活，有时放在关系代词之前，有时放在动词之后。
如：when=in/on/at…+which, where=in/on/at…+which， why=for+which 如:I won’t forget the date when( on which）I was born.This is the room where （in which) I lived. = This is the room which I lived in.I don’t know the reason why （for which) he hasn’t come today.Tom still remembers the days when （in which）they lived in Tianjin。
定语从句中的介词可提前的全部情况
定语从句中的介词可提前的全部情况关系代词whom或which在定语从句中作介词宾语时,介词可放在后面,也可提前构成介词+关系代词whom (先行词指人)/which(先行词指物)引导定语从句(这种方法更为正式)。
例: Mary is the girl whom I borrowed a book from. = Mary is the girl from whom I borrowed a book. 玛丽就是我向她借书的那个女孩。
Is this the room that/which he once lived in? = Is this the room in which he once lived? 这是他曾经住过的房子吗?常见的有以下几种情况:1. where=in/on which 例:This is the room where / in which he lives.这是他住的房间。
I can see the playground where / on which they do sports.我能看见他们进行运动的操场。
2. when= on/in/at which 例:I still remember the year when/ in which I joined the Party.我仍然记得入党的那一年。
I still remember the day when/on which I joined the Party. 我仍然记得入党的那一天。
I still remember the hour when/at which the rocket was launched.我仍然记得那个火箭发射的时刻。
3. why=for which 例:This is the reason why / for which he was killed.这是他被杀害的原因。
但下列情况下介词不能提前:⑴用who代替whom,用that代替which时,介词不能提前。
定语从句不用that的情况
定语从句不用that的情况定语从句不用that的情况定语从句中比较容易处理方面是，定语从句中“that”多可省略，表现为关系代词作宾语的情况，下面是店铺给大家整理的定语从句不用that的情况的相关内容，希望能给你带来帮助!（一）定语从句不用that的情况1、不能用that的情况介词前置时；非限定性定语从句中先行词本身是that多用who，不用that的情况先行词为anyone，one，ones时；先行词为those，he和people时；这些词代替指人，whom在定语从句中指人，"who"和“that”既可作主语又可作宾语（作宾语可以省略,who作宾语变为whom），that可以指人也可以指物, who不可指物。
在从句中所起作用如下：（1）Is he the man who/that wants to see you? 他是那个想见你的男人吗？（who/that在从句中作主语）（2）He is the man （whom/that） I saw yesterday. 他就是我昨天见到的那个人。
（whom/that在从句中作宾语）（3）The man whom you spoke to just now is our English teacher. 刚刚和你说话的那个男人是我们的英语老师。
（whom在从句中作宾语）注：who在定语从句中指人，作主语和宾语，作宾语时可省略；做及物动词或介词的宾语，可省略。
which，that 用来指物（有六种情况只可用that而不用which）(用作主语、宾语，作宾语时可以省略），例如：（1）The prosperity which/that had never appeared before took on in the countryside.农村出现了前所未有的繁荣。
（which/that在从句中作主语）（2）The package (which/that) you are carrying is about to comeunwrapped.你拿那个包裹快要散开了。

介词提前的定语从句
介词提前的定语从句在英语语法中，定语从句是一种常用的句子结构，用于修饰名词或代词。
它通过引导词（关系代词或关系副词）与先行词之间的关系来提供进一步的信息。
在定语从句中，我们通常将引导词放在句子的末尾。
然而，在某些情况下，我们可以将介词提前到定语从句的引导词之前，以达到一种更加自然和流畅的表达方式。
介词提前的定语从句的常见情况是在关系代词之前加上介词。
这样做的好处是使句子更加简洁明了，并且可以避免使用复杂的介词短语结构。
例如：1.The book on which I'm reading is very interesting.→The book I'm reading is very interesting.（我正在读的那本书非常有趣。
）2.The girl with whom I went to the party is my best friend.→The girl I went to the party with is my best friend.（我和她一起去参加派对的那个女孩是我最好的朋友。
）3.The restaurant in which we had dinner last night was expensive.→The restaurant we had dinner in last night was expensive.（我们昨晚吃饭的那家餐厅很贵。
）通过将介词提前，我们可以使句子更加简洁，并且更符合日常口语的表达习惯。
这种结构在口语和书面语中都非常常见，而且能够帮助我们更好地理解句子的含义。
需要注意的是，不是所有的介词都可以提前到定语从句的引导词之前。
只有一些常见的介词，如with、in、on、for等可以进行提前。
而其他一些介词，如to、at、from等则不能进行提前。
因此，在使用介词提前的定语从句时，我们需要根据具体的语境和常用表达习惯来判断是否适用。
(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。

定语从句介词提前用法
定语从句介词提前用法定语从句是英语中非常重要的一种语法结构，它可以用来修饰名词或代词，进一步描述或限定其所指的对象。
而介词提前则是定语从句中常用的一种表达方式，它可以使句子更加简洁明了，也更符合英语语言的表达习惯。
介词提前的用法可以通过以下例句来理解：1. The book on the table, which I borrowed from the library, is very interesting.这句话中，介词on被提前到定语从句的开头，修饰名词table。
定语从句的主语是I，谓语是borrowed，关系代词which指代的是book。
2. The girl in the red dress, whom I met yesterday, is my new neighbor.这句话中，介词in被提前到定语从句的开头，修饰名词dress。
定语从句的主语是I，谓语是met，关系代词whom指代的是girl。
3. The man with the beard, whose car was stolen, reported thetheft to the police.这句话中，介词with被提前到定语从句的开头，修饰名词beard。
定语从句的主语是car，谓语是was stolen，关系代词whose指代的是man。
通过以上例句可以看出，介词提前的用法可以使定语从句更加简洁明了，同时也可以使句子的语气更加自然流畅。
在实际应用中，我们可以根据需要灵活运用介词提前的用法，使句子更加优美。
除了介词提前，定语从句还有其他的表达方式，比如关系代词的省略、关系代词的替换等。
在使用定语从句时，我们需要注意以下几点：1. 关系代词的选择：在定语从句中，关系代词的选择要根据其在从句中所扮演的角色来确定。
比如，主语要用who或that，宾语要用whom或that，所有格要用whose等。
2. 关系代词的位置：在定语从句中，关系代词的位置要放在从句中所修饰的名词或代词之后，这样才能清晰地表达出其所指代的对象。
定语从句语法归纳
高一定语从句语法归纳及练习一、语法知识归纳一、基本概念（一）定语从句在复合句中作定语，修饰名词或代词的从句叫定语从句。
（二）先行词被定语从句所修饰的名词或代词。
一般情况下，定语从句紧跟先行词。
但也有因各种原因定语从句与先行词被分割的现象。
（三）关系代词和关系副词定语从句的引导词。

关系副词有：when, where和why。
在定语从句中充当状语。
二、关系代词的用法（一）基本用法根据先行词的不同，和在从句中所充当的成分不同，选用不同的关系代词。
