高中英语定语从句详解
定语从句详解Ⅰ. 概念：定语从句:在复合句中修饰名词或代词的句子在复合句中充当定语，所以叫作定语从句。
先行词：定语从句所修饰的名词或代词。
关系词：引导定语从句的词，分为关系代词（who,whom,that,which,whose）和关系副词(where,when,why,)。
复合句：The man who (that) came is Mike.先行词关系代词Li Ming is the one that got full marks in our class.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、as 、but (文语, 置于否定词之后=that/who…not…, "没有……不……", 在从句中作主语，宾语)常用的关系副词（在从句中只作状语）: when、why、whereThe 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 looks out over 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、宾语或状语）；第三选择合适的关系词。
一. 几个关系代词的基本用法：1. 定语从句的关系代词Which的用法:若先行词指物则代替先行词在定语从句中充当主语或宾语.This is the pen which was given by my friend.先行词指物代替先行词在定语从句中充当主语This is the pen which my friend gave to me.先行词指物代替先行词在定语从句中充当宾语2. 定语从句的关系代词Who的用法: 若先行词指人则代替先行词在定语从句中充当主语或宾语(如果前面带介词则必须用whom)The man who is wearing a white suit is my brother.先行词指人代替先行词在定语从句中充当主语The man who\whom he wanted to see last week is in Shanghai.先行词指人代替先行词在定语从句中充当宾语She is the girl with whom I went there.先行词指人代替先行词在定语从句中充当介宾且介词于前.3. 定语从句的关系代词Whom的用法: 若先行词指人则代替先行词在定语从句中充当宾语(包括介词的宾语) ,与who的区别是如果前面带介词则必须用whomThis is the teacher whom\who we like best.先行词指人代替先行词在定语从句中充当宾语She is the girl whom\ who I went with there.先行词指人代替先行词在定语从句中充当介宾.I do n’t like the boy to whom you are talking.先行词指人代替先行词在定语从句中充当介宾且介词于前. 4. 定语从句的关系代词that的用法: 若先行词指人或物则代替先行词在定语从句中充当主语或宾语The animal that \which is lost is a panda.先行词指物代替先行词在定语从句中充当主语She is the person that \who we are worried about.先行词指人代替先行词在定语从句中充当宾语定语从句的关系副词Where的用法:若先行词指地点且其在定语从句中充当地点状语.This is the house+I was born in the house. (=I was born there)介词短语副词这就是我在那儿出生的房子.I was born in.这里作介宾的which和that可以省略I was born in练习：用which ，where填空1 This is the factory they want to visit。

高中定语从句详细讲解高中定语从句详细讲解高中定语从句详细讲解一.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/why5.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“o f 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.)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)3.在非限定性定语从句中，任何引导词都不能省略(包括引导词在此定语从句中充当宾语在内)。
指人做主语时只能用who, 做宾语时用whom;指物做主语，宾语都用which; 关系副词用when或where,也不能省略。
The man, ______ is sitting on the chair, is my father.The woman, _______ I met yesterday, is my English teacher.The city, _______ is far away, is very beautiful.He went to America, ______ his parents live.He joined the Army yesterday, ______ I left, too.4.whose引导非限定性定语从句：The house, whose window faces south, is mine.=The house, the window of which faces south, is mine.=The house, of which the window faces south, is mine.二。
定语从句中关系代词和关系副词的基本用法。
1.who/that指人是主格在定语从句中代替先行词，又作定语从句的主语，不能省略。
Do you know the gentleman who/that is sitting there?2.whom/who/that指人是宾格，在定语从句中代替先行词，又作定语从句的宾语(动宾或介宾)。
① 当作动宾(动词后接宾语)时，关系代词可省略。
Do you know the gentleman (whom/who/that) we met just now?② 当作介宾(介词后接宾语)时：介词不提前时，关系代词可省略;介词提前时，关系代词不可省，即介词+whom(指人时介词后的关系代词只能用whom)。
The man (whom/who/that) I spoke with is my teacher.The man with whom I spoke is my teacher.※注：固定的动词短语(动词+介词)如look for, take care of等不能把动词与介词拆开，既介词不能提至引导词前。
She is the right girl (who/whom/that) we are looking for.3.whose: 指人或物，是所有格“…的”形式。
Whose+n.一起在定语从句中充当主语、宾语(动宾或介宾)即先行词的什么东西怎样了，whose不能省略。
Whose+n. = the +n. + of which/whom= of which/ whom+ the =n.I didn’t find the desk whose leg was broken. (主语)He is the student whose pencil I broke yesterday. (动宾)The boss in whose company I work is very kind. (介宾)4.which/that 指物，指代先行词且在定语从句中作主语或宾语(动宾或介宾)。
① 当作动宾时，关系代词可省略。
② 当作介宾时：介词不提前时，关系代词可省略;介词提前时，关系代词不可省，即介词+which(指物时介词后的关系代词只能用which)。
The house which/that was destroyed in the earthquake is weak.The pen (which/that) you found yesterday is mine.The games (that/which) the young men competed in were difficult.The games in which the young men competed were difficult.※注：介词+关系代词即介词+whom/which(先行词指人用whom,指物用which)。
※5.as指人或物，在定语从句中可作主语，宾语，表语或状语，不能省略。
主要用于“the same …as…;such …as…;so …as…;as … as…;as follows”固定结构中，形式固定此时的引导限定性定语从句。
要用as代替who(m), which, 或that引导定语从句：Such people as knew Hill thought he was honest.Such people as Hill knew thought he was honest.My hometown is no longer the same as it was.Here is so big a stone as no one can lift.The child knows as much as grow-ups (know).I’d like to have the same books as are used in your school.He is not such a person as I expected.He will marry as pretty a girl as he can find.※注：which和as可引导非限定性定语从句：可以指代主句中的一部分或整个句子的.内容，which和as都可以指代主句中的一部分或整个句子的内容，有时可以互换。
因此，当as/which指代前面的整个句子，或前句中的部分内容作定语从句的主语时，谓语用单数。
Our team lost the game, as/which was reported in the newspaper.She was terrified, as/which I could see from her eyes.He married her, as/which was natural.区别：①as引导的非限制性定语从句可以放在主句前面、插在主句中间或放在主句末尾;而which引导的非限制性定语从句只能放在主句后面。
