《定语从句》 讲义
《定语从句》讲义一、定语从句的定义和作用定语从句是一种在英语中非常常见且重要的语法结构。
它在句子中充当定语，用来修饰一个名词或代词，使其含义更加明确和丰富。
简单来说，定语从句就是一个句子，放在被修饰的名词或代词后面，起到描述和限定的作用。
通过定语从句，我们能够更详细、更准确地表达我们想要表达的意思。
比如，“The book that I bought yesterday is very interesting”（我昨天买的那本书非常有趣。
）在这个句子中，“that I bought yesterday”就是一个定语从句，用来修饰先行词“the book”，让我们清楚知道是哪一本书有趣。
二、定语从句的构成定语从句通常由关系词（关系代词或关系副词）引导。
常见的关系代词有：that、which、who、whom、whose。
常见的关系副词有：when、where、why。
关系词在定语从句中不仅起到引导的作用，还在从句中充当一定的成分。
例如，在“The man who is standing there is my teacher”这个句子中，“who”是关系代词，在从句“who is standing there”中作主语。
三、关系代词的用法1、 that 和 whichthat 和 which 都可以用来指代物，但在一些情况下，只能用 that 不能用 which。
当先行词是不定代词（如 all、anything、nothing 等）、先行词被最高级、序数词修饰、先行词既有人又有物时，通常用 that 而不用 which。
例如：All that glitters is not gold（发光的未必都是金子。
）This is the first book that I have read（这是我读过的第一本书。
）The man and the horse that fell into the river were drowned（掉进河里的人和马都淹死了。
英语定语从句讲义全
定语从句（一）基本概念1.由一个句子作定语，修饰句中一个名词或代词，有时也可以修饰整个句子或句中的部分内容，这样的从句就是定语从句，被其修饰的名词或代词叫先行词。
2.关系词分为两大类，即关系代词和关系副词，其作用一是引出一个定语从句，二是代替其所修饰的先行词，三是在句中充当某个句子成分。
关系词的分类和基本用法（二）定语从句的注意点本部分的内容比较复杂，为便于考生一目了然，我们试图用表格的形式呈现给考生。
1.that与which, who, whom的用法区别2.as、which和that的区别3. where、when与why引导的定语从句4.“介词+关系代词”引导的定语从句当关系代词作介词宾语，且该介词不是和从句的谓语动词构成固定短语时，介词可以提前，这样就出现“介词+关系代词”。
先行词指物，用“介词+which/whose”,指人则用“介词+whom/whose”, 且两个关系代词均不能省略。
介词的选择要遵循两个原则：5.定语从句与先行词被分割开来的现象定语从句一般紧接被它所修饰的先行词；但有时候它和先行词之间有可能插入其他成分，使它与先行词分隔开来，这种定语从句叫作被分隔的定语从句，在阅读文章时会经常遇到这种情况，在阅读是要注意识别先行词的修饰对象。
6.定语从句与其它从句（句型）的区别此外还要注意下列两点：▲定语从句与习惯句型用一个恰当的词完成下列句子，使之完整与正确。
①It is the first time _____ she has been in Shanghai．②It was the time _____ Chinese people had a hard life．解析：这里①小题是一个习惯句型，其结构为：It is／was the first／second ．．．time ＋that从句。
故①填that，其意为：这是她第一次在上海。
②小题the time是先行词，其后是表示时间的定语从句，故填when。

定语从句基础知识讲义I •定语从句基本知识点基本概念：①在复合句屮修饰名词或代词的从句叫定语从句。
定语从句在句屮的作用相当于一个形容词，因此也叫形容词性从句。

3.关系词：引导定语从句的词叫关系词。
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when, where, why等。
关系词通常有下列三个作用：A.引导定语从句B.代替先行词,C.在定语从句中担当一个成分二．关系代词表格例如：（注意关系代词在定语从句中所充当的成分）① Do you know the professor who/that will give us a speech next week? （作主语）② I read a report about his new novel that/ which will soon be published. （作主语）③ The plan that/which they argued about was settled at last. （作宾语）④ This is the new secretary (who/whom/that) I would like to introduce to you. （作宾语）⑤ The soldier whose legs were badly wounded was operated on without delay. （作定语）三．6个关系代词的用法1）关系代词that和which的用法which, that 在代替物时，一般可以通用。
His father works in a factory that/which makes TV sets.The coat (which/that) I put on the desk is black.▲但在有些情况下，只用that1.先行词是最高级形容词或它的前面有最高级形容词修饰时。
① This is the best way that has been used against pollution.② English is the most difficult subject that you will learn during these years.2.先行词是序数词，或它前面有一个序数词时。
① This is the last place (that) I want to visit.② It is the first American movie of this kind that I’ve ever seen.3.先行词是all, much, little, something, everything, anything, nothing, none,any, few, little, no, all, much, every等不定代词时。
① You should hand in all that you have.② We haven’t got much that we can o ffer you.③The little money (that) he had was stolen.4.先行词前面有the only, the very,等修饰时。
The only thing that we can do is to give you some money.5.先行词既有人又有物时。
Do you know the things and persons that they are talking about?6.主句已有疑问词which时。
避免重复使用Which is the bike that you lost?7.that 在定语从句中作表语Mary is no longer the girl that she used to be.▲不用that的情况①引导非限定性定语从句时。
例如：He takes exercise everyday, which has done a lot of good to his health.②介词后不能用。
We depend on the land from which we get our food.▲有些情况只用which①引导非限定性定语从句修饰某物或整个句子。
Bruce went towards the fire, which was still smoking.Tom came back late, which made his parents very angry.②关系代词作介词的宾语。
This is the house in which Lu Xun once lived.2）关系代词who和whom的用法who指人，在句中作主语和宾语，作宾语可省略。
Whom指人，在句中只能作宾语，可省略，但在介词后面不能省略。
She has a brother who worked at that factory ten years ago.The doctor who/whom/that /x she went to the United States with last month is very famous. =The doctor with whom she went to the United States last month is very famous.3）关系代词whose的用法⑴ whose是代词的所有格，它既可以代人也可以代物。
① I saw a woman whose bag was stolen.② Please show me the book whose cover is red.⑵当whose表示物与物的所有格关系时，亦可用of which的形式。
① The building whose roof you can see from here is a new restaurant.→ The building, the roof of which you can see from here, is a new restaurant.或→ The building, of which the roof you can see from he re is a new restaurant.4）关系代词as的用法先行词前有such、the same时关系代词用asI’ve never heard such stories as he tells.He is not such a fool as he looks.This is the same dictionary as I lost last week.5）关系副词的用法含义相当于\"介词+ which\"结构，因此常常和\"介词+ which\"结构交替使用关系副词引导的定语从句① when 指时间，在定语从句中作时间状语。
I still remember the day when I first came to this school.The time when we got together finally arrived.② where 指地点，在定语从句中作地点状语。
Shanghai is the city where I was born.The house where I lived ten years ago has been pulled down.③why 指原因，在定语从句中作原因状语。
Please tell me the reason why you missed the plane.when=on which where=in which reason=for whichThe day when /on which I met him first was May 1st.This is the house where/in which I lived two years ago.I don’t know the reason why /for which he didn’t come..并非先行词表示时间或地点时都分别用when或where来引导相应的定语从句，若关系词在修饰表示时间或地点的先行词的定语从句中充当主语、宾语等而不是状语时，需用which或that引导相应的定语从句。
Do you still remember the days which/that we spent together in school? 先行词the days表时间，但是其定语从句的引导词在定语从句中作宾语而不是状语，因此不能用when而应该用which或that。
This is the day when I joined the party/which he spent reading the books/which I still never forget. This is the place where I found the book./ which we once visited/which I will never forget/which I am looking forThis is the reason why he was late /that he gave at the meeting for his being late.④.以the way为先行词的限制性定语从句通常由in which或that引导，而且通常可以省略。
The way (that / in which ) he answered the questions was surprising.I don’t like the way (that / in which) you laugh at her.四．介词+关系代词关系代词在定语从句中作介词宾语时，从句常常由“介词+关系代词”引出。
介词+which（指事）介词+whom（指人）①The school (which / that) he once studied in is very famous.The school in which he once studied is very famous.②Tomorrow I’ll bring here the magazine (which / that) you asked for.Tomorrow I’ll bring here the magazine for which you asked.③This is the boy (whom / who / that) I played tennis with yesterday.This is the boy with whom I played tennis with yesterday.④We’ll go to hear the famous singer (whom / who / that) we have often talked about.We’ll go to hear the famous singer about whom we have often talked.⑤The boss whose company I work in pays much attention to improving our working conditions. The boss in whose company I work pays much attention to improving our working conditions. 若介词放在关系代词前，关系代词指人时只可用whom，不可用who, that；关系代词指物时只可用which，不可用that。
