why引导定语从句表原因，先行词一般是reason等表示原因的词。
例句：This is the reason why I didn’t come here.
= This is the reason for which I didn’t come here.

7. 当先行词前面有who, which等疑问代词时。如：

Which is the T-shirt that fits me most?
注意：that，who不能用于介词后！！！
Eg. I have a friend ____ I work.
A. who
B. whom
C. with who
D. with whom
非限定性定语从句
非限定性定语从句用来提供附加的而非必要的信息，只是对先行词作进一步的解释，补充或说明。若去掉，主句意思依旧明确。
I do n’t like people who are never on time. 我不喜欢不守时的人。
My mother, who is 50, lives with me now. 我妈50岁了，和我生活在一起。She made a boyfriend, which made her mother angry.
※非限定性定语从句用逗号隔开，限定性定语从句不用逗号隔开。
that不可用于非限定性定语从句中。
关系代词as和which 引导的定语从句
as 和which 引导非限制性定语从句时，其用法有相同之处，也有不同之处。具体情况是：1. as 和which都可以在定语从句中做主语或宾语，代表前面整个句子。如：
He married her, as / which was natural. 他跟她结婚了，这是很自然的事。
He is honest, as / which we can see. 他很诚实，这一点我们看得出来。
2. as 引导的非限制性定语从句可以放在主句之前、主句之后，甚至还可以分割主句。 which 引导的非限制性定语从句只可放在主句之后。另外，as 常常有“正如、正像”的含义。如：
As is known to all, China is a developing country. 众所周知，中国是发展中国家。
He is from the south, as we can know from his accent. 他是南方人，这一点我们从他的口音可以知道。
John, as you know, is a famous writer. 正如你所知，约翰是个著名作家。
Zhang Hua has been to Paris more than ten times, which I don’t believe. 张华已去过巴黎十多次了，这一点我不相信。
注意：当主句和从句之间存在着逻辑上的因果关系时，关系词往往只用which。如：
Tom was late for school again and again, which made his teacher very angry. 汤姆老是迟到，这使得老师很恼火。
These tables are made of metal, which made them very heavy. 这些桌子是金属的，这使得这些桌子很重。
1. 当先行词受such, the same 修饰时，关系词常用as。如：
I’ve never heard such stories as he tells. 我从未听过象他讲的这样的故事。
He is not such a fool as he looks. 他可不象他看上去的那样傻。
This is the same dictionary as I lost last week. 这部词典跟我上星期丢失的一样。
高中高一英语定语从句语法复习 一．几个基本概念 1.定语从句的定义：用作定语的从句叫定语从句。 2.先行词：被定语从句所修饰的名词或代词。 3.定语从句的位置：紧跟先行词（名词或代词）之后。 4.引导词：引导定语从句的词（包括关系代词和关系副词）。 ﹙1﹚关系代词：that/who/whom/which/as ﹙2﹚关系副词：when/where/why 5.引导词的位置：位于定语从句之前（先行词之后）。【as除外】 6.引导词的功能（作用）： ﹙1﹚连接先行词和定语从句。 ﹙2﹚在定语从句中充当一定的成分（关系代词充当主语或宾语，关系副词充当状语）。 7.定语从句的类型： ﹙1﹚限定性定语从句（主句和定语从句之间无逗号）。 ①直接由引导词引导定语从句 The man who you’re talking to is my friend. ②由介词+关系代词（whom/which）引导 The man to whom you’re talking is my friend. I need a pen with which I can write a letter. =I need a piece of paper on which I can write a letter. 介词的选用可根据从句中的相关词组确定，该介词通常可以放在关系代词之前，也可放在从句之尾。例如： The man (who/whom/that) I talked about at the meeting is from Beijing University. =The man about whom I talked at the meeting is from Beijing University. The palace (which/that) I often pay a visit to was built in the 17th century. =The palace to which I often pay a visit was built in the 17th century. ﹙2﹚非限定性定语从句（主句和定语从句之间用逗号隔开）。 ①直接由引导词引导定语从句。 ②由介词+关系代词（whom/which）引导。 I live in a house far away from the city, in front of which is a big tree. There is an apple tree standing at the gate, on which are many apples. This is the man to whom I gave the book. ③由“代词/名词+of+whom/which”或“of which/ whom +名词/代词”(先行词指 人用whom,指物用which)引导。One, some, any, none, all, both, several, many, most, neither, either等词、数词、分数或百分比与of whom或of which连用。 He has five children, two of whom are abroad. (比较：He has five children, and two of them are abroad.)
高中英语语法定语从句总复习 郴州资兴三中李俊才 定义：用来说明主句中某一名词或代词（有时也可说明整个主句或主句中一部分）而起定语作用的句子叫 作定语从句。 一、关系带词引导的定语从句 1. 关系代词用来指代先行词是人或物的名词或代词 句子成分用于限制从句或非限制性从句只用于限制性从句 代替人代替物代替人或物主语Who which 主语Whom which that 宾语Whose (=of whom) Whose (=of which) that 例１：This is the detective who came from London. 例２：The book which I am reading is written by Tomas Hardy. ２．关系代词的用法 (1) 如果先行词是all, much, anything, something, nothing, everything, little, none等不定代词，关系代词一般只用that，不用which。例如： All the people that are burst into tears.（所有人都迸出眼泪。） (2) 如果先行词被形容词最高级以及first, last, any, only, few, most, no, some, very等词修饰，关系代词常用that,不用which, who，或whom。 (3) 非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不能省略。 There are about seven million people taking part in the election, most of whom、are well educated. (4) which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分 概念。在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与and this 相似，并可以指人。例如： He succeeded in the competition, which made his parents very happy. (5) that可指人或物，在从句中作表语，（指人作主语时多用who）仅用于限制性定语从句中。
高中英语语法系列：定语从句 知识要点 1.关系代词和关系副词的选用 2.限制性定语从句和非限制性定语从句的区别 3.几组的关系词特殊用法 一、定义：在复合句中，修饰名词或代词的从句叫做定语从句。 The happy man who lives next to me sells vegetables. You must do everything that I do. 被定语从句修饰的词，叫先行词。比如上面两句中的man和everything. 引导定语从句的词，叫关系代词和关系副词。比如who,whom,that,which,wh ere,when,why等 关系词三重作用：①连接主从句；②指代先行词；③在定语从句中担任句子成分。 The man who lives next to me sells vegetables. 该句中，who lives next to me是定语从句，修饰先行词the man，“who”是引导定语从句的关系词，代替先行词the man，在定语从句中作主语。 二、关系词 引导定语从句的关系代词有who,whom,which,that,whose,as等和关系副词w here,when,why等。关系代词和关系副词在定语从句中担任句子成分。
1.用关系代词that,which,who,whom引导的定语从句 who指人，用作主语 whom指人，用作宾语 which指物，用作主语、宾语皆可 that指人和物，用作主语、宾语皆可 The teacher who visits our school today is from Guangzhou. Mrs Read is the person whom you should write to. They planted some trees which didn’t need much water. The fish(which)we bought this morning were not fresh. A plane is a machine that can fly.

(2)where在从句中作地点状语 I recently went to the town where(=in which)I was born. (3)why在从句中作原因状语 The reason why(=for which)he was late was that he missed the train.
高中英语语法通霸1. 句子结构成分分析主语谓语宾语定语状语补语定语
英语的句子成分主要有六种：即主语、谓语、宾语、定语、状语和补语。（可以熟记为：主谓宾，定状补）除了这六种主要成分之外，还有“表语”和“同位语”的说法。但表语和系动词一起作谓语，因此划分成分时，划分在谓语上。同位语分为主语同位语和宾语同位语，属于主语或宾语的一部分。 考点1.划分句子成分时的常用符号 英语中划分句子成分的符号 主语在下面画直线 谓语在下面画曲线 宾语在下面画双横线 定语在下面画虚线（一行点使我们想到一排钉子，“钉”谐音为“定语”的“定”） 状语下面为短横线（短横线使我们想到短木桩，木桩撞（状）钟） 补语上一短横，下一短横（下一短横好像是为了弥补上面短横间的空隙） 同位语上下双曲线（都有曲折，上下位置基本相同） 考点1.主语 主语是一个句子所叙述的主体，一般位于句首，通常由名词性的词来充当。 可以作主语的词性或语法结构： 1. 名词 2. 代词 3. 数词 4. 不定式 5. 动名词 6. 主语从句等表示。 7. 名词化的形容词（如the rich） 在英语中，形容词、副词和介词短语是不能作主语的。如果它们在句首时，句子可能是倒装句，真正的主语在后面。 On the desk are some books. (主语是books，所以用are) Down jumps the boy. (主语是the boy，所以用jumps ) Gone are the days. (主语是the days，所以用are) 练习1.在下面句子的主语下面画横线，并说出由什么充当。 1.During the 1990s, American country music has become more and more popular. 2.We often speak English in class. 3.One-third of the students in this class are girls. 4.To swim in the river is a great pleasure. 5.Smoking does harm to the health.
非限定性定语从句是英语语法中从句的一种，是定语从句的分支之一。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。运用非限定性定语从句，尤其要注意其语法运用及其所表示的东西。 1 who引导的非限制性定语从句 Our guide，who was a French Canadian，was an excellent cook. 我们的向导，一个法裔加拿大人，擅长于烹调。 My gardener，who is very pessimistic，says that there will be no apples this year. 我家的园丁非常悲观，他说今年将不结苹果。 2 whom引导的非限制性定语从句。 关系代词whom用于指人，在句中作动词宾语和介词宾语，作介词宾语时，介词可位于句末。 如：Peter, whom you met in London, is now back in Paris. 彼得现在回巴黎了，你在伦敦见过他。 Mr Smith，from whom I have learned a lot，is a famous scientist. 史密斯先生是一位著名的科学家，我从他那儿学了许多东西。 3 whose引导的非限制性定语从句。 whose是关系代词who的所有格形式，在从句中作定语。whose通常指人，也可指动物或无生命的事物。 如：The boy, whose father is an engineer, studies very hard. 那位小男孩学习很努力，他的父亲是位工程师。 Above the trees are the mountains, whose magnificence the river faithfully reflects on the surface. 在树林的高处是山，其壮丽的景色完全映照在河面上。 The play，whose style is rigidly formal，is typical of the period. 这剧本是那个时期的典型作品，风格拘谨刻板。 4 which引导的非限制性定语从句。 关系代词which在非限制性定语从句中所指代和修饰的可以是主句中的名词、形容词、短语、其他从句或整个主句，在从句中作主语、动词宾语、介词宾语或表语。 ①which指代主句中的名词，被指代的名词包括表示物、婴儿或动物的名词、表示单数意义的集体名词以及表示职业、品格等的名词。 如：These apple trees，which I planted three years ago，have not borne any fruit. 这些苹果树是我三年前栽的，还没有结过果实。 She is an artist，which I am not. 她是一位艺术家，而我不是。 Water，which is a clear liquid，has many uses. 水是一种清澈的液体，有许多用途。 The two policemen were completely trusted，which in fact they were. 那两个警察完全受到信任，事实上，也真是如此。 ②which指代主句中的形容词。 如：She was very patient towards the children，which her husband seldom was. 她对孩子们很耐心，她丈夫却很少这样。 She is always careless，which we should not be. 她总是马虎大意，我们可不应该这样。 ③which指代主句中的某个从句。
高中英语定语从句讲解及练习 定语从句是高中重点知识，也是高考常考点，大家也不容易掌握，这篇文章主要教你关系代词引导的定语从句 关系副词引导的定语从句判断关系代词与关系副词限制性和非限制性定语从句等内容，有例题讲解定语从句在句中做定语，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。 关系代词有：who, whom, whose, that, which等。 关系副词有：when, where, why等。 18.1 关系代词引导的定语从句 关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、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。 1）who, whom, that 这些词代替的先行词是人的名词或代词，在从句中作主语和宾语。例如： Is he the man who/that wants to see you? 他就是你想见的人吗？（who/that在从句中作主语） He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语） 2）whose 用来指人或物，（只用作定语, 若指物，它还可以同of which互换）。例如： 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。 Please pass me the book whose （of which）cover is green.请递给我那本绿皮的书。 3）which, that所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等。例如： A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语） The package （which / that）you are carrying is about to come unwrapped. 你拿的包快散了。（which / that在句中作宾语） 18.2 关系副词引导的定语从句 关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。 1）关系副词when, where, why的含义相当于\"介词+ which\"结构，因此常常和\"介词+ which\"结构交替使用。例如： There are occasions when （on which）one must yield.任何人都有不得不屈服的时候。 Beijing is the place where（in which）I was born.北京是我的出生地。 Is this the reason why （for which）he refused our offer?这就是他拒绝我们帮助他的理由吗？ 2）that代替关系副词，可以用于表示时间、地点、方式、理由的名词后取代when, where, why和\"介+which\"引导的定语从句，在口语中that常被省略。例如： His father died the year （that / when / in which）he was born.他父亲在他出生那年逝世了。 He is unlikely to find the place （that / where / in which）he lived forty years ago. 他不大可能找到他四十年前居住过的地方。 18.3 判断关系代词与关系副词 方法一：用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如： This is the mountain village where I stayed last year. 这是我去年呆过的山村。 I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。 判断改错： （错）This is the mountain village where I visited last year. （错）I will never forget the days when I spent in the countryside. （对）This is the mountain village （which）I visited last year. （对）I'll never forget the days （which）I spent in the countryside. 习惯上总把表地点或时间的名词与关系副词where, when联系在一起。此两题错在关系词的误用上。 方法二：准确判断先行词在定语从句中的成分（主、谓、宾、定、状），也能正确选择出关系代词/关

高中英语定语从句详解 Ⅰ. 概念： (1) 定语从句：在主从复合句中用作定语的从句叫定语从句。定语从句一般紧接在先行词(antecedent)后面。 (2) 先行词：被定语从句修饰的成份。先行词可以为一个词，短语，或整个主句。 (3) 引导定语从句的词叫关系词，分为关系代词和关系副词。 关系词的作用： 1) 引导定语从句，连接主句和从句，相当于一个连词； 2) 必在从句中作某个句子成份（可以做主语，宾语，表语，定语，状语） 常用的关系代词: that、which、who、whom、whose,当关系代词在定语从句中做宾语时，关系代词可以省略。 常用的关系副词（在从句中只作状语）: when（时间状语）、why（原因状语）、where（地点状语） 可以修饰人的关系代词：that, who, whom, whose 可以修饰事的关系代词：that, which, as, whose, The student who answered the question was John. I know the reason why he was so angry. The boy (whom) you are talking to is my brother. I'd like a room whose window faces the sea. 定语从句三步： 第一找出先行词； 第二看先行词在定语从句中的语法功能（做主语、宾语、表语或状语）； 第三选择合适的关系词。 Ⅱ. 几个关系代词的基本用法： ●that: 可指人或物；在定语从句中作主语，宾语，表语。(指人时，相当于who 或whom；指物时，相当于which)(一般不用于非限制性定语从句; 不可置于介词后作宾语) 如： 1. A letter that/which is written in pencil is difficult to read. (主语) 2. Do you know the gentleman that/who spoke just now? 3. You can take anything ( that) you like. （宾语） 4. What is the question (that/which) they are talking about? 5. Here is the man ( who/whom/that ) you want to see. 6. She's no longer the girl ( that) she used to be before.（表语） 7. Our hometown is no longer the one (that) it used to be. （= Our hometown is not the same as it used to be. = Our hometown is different from what it used to be。 = Our hometown is not what it used to be.） ●which: 指物；在定语从句中作主语，宾语。如： 1.

高中定语从句详细讲解 （一）定义及相关术语 1．定语从句：修饰某一名词或代词的从句叫定语从句。定语从句一般紧跟在它所修饰的先行词之后。 2．先行词：被定语从句修饰的词叫先行词。 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。例如： The man who is shaking hands with my father is a policeman. 该句中，who is shaking hands with my father 是定语从句，修饰先行词the man，“who”是引导定语从句的关系词，代替先行词the man，在定语从句中作主语。 （二）关系代词引导的定语从句 1．who 指人，在定语从句中作主语。 The boys who are playing football are from Class One. 正在踢足球的男孩是一班的。Those who want to go to the museum must be at the school gate at 7 tomorrow morning. 想去博物馆的人必须在明晨7点到大门口集合。 Yesterday I helped an old man who had lost his way. 昨天我帮助了一位迷路的老人。That is the teacher who teaches us physics. 那就是教我们物理的老师。2．whom 指人，在定语从句中做宾语，常可省略。 Mr Liu is the person ( whom ) you talked about on the bus. 刘先生就是你们在公共汽车上谈论的那个人。 Li Ming is just the boy ( whom ) I want to see. 李明正是我想要见的男孩。 The professor ( whom ) you are waiting for has come. 你正在等的教授已经来了。 The girl ( whom ) the teacher often praises is our monitor. 老师经常表扬的那个女孩是我们的班长。 注意：关系代词whom 在口语或非正式文体中常可用who 来代替，也可省略。 The man ( whom / who )you met just now is my old friend. 3．Which 指物，在定语从句中做主语或宾语，做宾语时常可省略。 Football is a game which is liked by most boys. 足球是大多数男孩所喜欢的运动。 The factory which makes computers is far away from here. 制造计算机的那家公司离这儿很远。 He likes to read books which are written by foreign writers. 他喜欢外国作家写的书。 The house which is by the lake looks nice. 湖边的那幢房子看上去很漂亮。 This is the pen ( which ) he bought yesterday. 这是他昨天买的钢笔。 The film ( which ) they went to see last night was not interesting at all. 他们昨晚看的电影一点意思也没有。 4．That 指人时，相当于who 或whom；指物时，相当于which.。在定语从句中作主语或宾语，作宾语时常可省略。 The number of people that / who come to visit this city each year reaches one million. 每年来参观这座城市的人数达一百万。 Where is the man that / whom I saw this morning? 我今天早上看到的那个人在哪儿？
高中英语定语从句语法复习 (名师精讲必考知识点，值得下载练习) 一．几个基本概念 1.定语从句的定义：用作定语的从句叫定语从句。 2.先行词：被定语从句所修饰的名词或代词。 3.定语从句的位置：紧跟先行词（名词或代词）之后。 4.引导词：引导定语从句的词（包括关系代词和关系副词）。 ﹙1﹚关系代词：that/who/whom/which/as ﹙2﹚关系副词：when/where/why 5.引导词的位置：位于定语从句之前（先行词之后）。【as除外】 6.引导词的功能（作用）： ﹙1﹚连接先行词和定语从句。 ﹙2﹚在定语从句中充当一定的成分（关系代词充当主语或宾语，关系副词充当状语）。 7.定语从句的类型： ﹙1﹚限定性定语从句（主句和定语从句之间无逗号）。 ①直接由引导词引导定语从句 The man who you’re talking to is my friend. ②由介词+关系代词（whom/which）引导 The man to whom you’re talking is my friend. I need a pen with which I can write a letter. =I need a piece of paper on which I can write a letter.
介词的选用可根据从句中的相关词组确定，该介词通常可以放在关系代词之前， 也可放在从句之尾。例如： The man (who/whom/that) I talked about at the meeting is from Beijing University. =The man about whom I talked at the meeting is from Beijing University. The palace (which/that) I often pay a visit to was built in the 17th century. =The palace to which I often pay a visit was built in the 17th century. ﹙2﹚非限定性定语从句（主句和定语从句之间用逗号隔开）。 ①直接由引导词引导定语从句。 ②由介词+关系代词（whom/which）引导。 I live in a house far away from the city, in front of which is a big tree. There is an apple tree standing at the gate, on which are many apples. This is the man to whom I gave the book. 先行词指 ③由“代词/名词+of+whom/which”或“of which/ whom +名词/代词”（ 人用whom,指物用which)引导。One, some, any, none, all, both, several, many, most, neither, either等词、数词、分数或百分比与of whom或of which连用。 He has five children, two of whom are abroad. (比较：He has five children, and two of them are abroad.) We have three books, none of which is/are interesting. (比较：We have three books, but none of them is/are interesting.) 除why和that不能引导非限定性定语从句外，其余引导词都可以，用法同限定 性定语从句一样。但要注意以下区别。 1.在形式上非限定性定语从句与主句有逗号隔开。 2.非限定性定语从句的作用：它只是补充说明先行词的情况，翻译时可译成两个 句子。 The engineer, whose leg was badly hurt, was quickly sent to hospital. （那位工程师被很快送往医院，其腿部受了重伤） The engineer whose leg was badly hurt was quickly sent to hospital. （那位腿部受了重伤的工程师被很快送往医院）
