（完整版）定语从句讲解总结
（完整版）定语从句讲解总结定语从句讲解⼀．定语从句1.注意英汉差异：汉语的定语⽆论多长都放在被修饰词的前⾯，⽽英语中的定语则不然，是⼀个词时，放在被修饰词的前⾯，如：①.a beautiful girl ②.a lovely boy是两个以上的词组、短语或从句则放在被修饰词的后⾯，如：③.She is the girl in red. 她就是穿红⾐的⼥孩。
④.The lady carried a bag full of money. 那位⼥⼠背了个装满钱的包。
⑤.He is the man who you are looking for. 她就是你在找的⼈。
2.分清主句与从句，看究竟哪个句⼦缺少成分。
如上⾯第5：主句：He is the man从句：who you are looking for在从句中，looking for 的宾语是the man.因此选⽤关系代词 who(whom)放置于句⾸，便是定语从句。
3.从句中做宾语的关系代词可以省略，故第5题可以写成：He is the man you are looking for.⼆．定语从句（从句部分）1、功能：相当于形容词，修饰名词或代词，在句中作定语2、位置：定语从句置于被修饰词之后Those who are willing to attend the party, sign here please.3、先⾏词：被定语从句修饰的词称为先⾏词（1）先⾏词⼀般是名词和不定代词，如:some-, any-, every-和no与-boy, -thing的合成词；或all、none、any、some、that、those等代词。
数词也可以作先⾏词，⼈称代词也同样可作先⾏词。
（2）先⾏词与关系词是等量关系。
必须注意两点：①先⾏词在从句中作主语时，从句谓语动词的数由先⾏词⽽定。
This is the place which is worth visiting.②关系词在从句句⼦中充当了成分，其意思就是先⾏词的意义，所以在从句中不能重复其意。

高一必修一定语从句知识点
高一必修一定语从句知识点在英语学习中，掌握定语从句是非常重要的一个知识点。
定语从句可以用来修饰名词，使句子更加丰富多样，表达更加准确。
而限定从句则是其中的一种形式，它用来限定或修饰先行词，进一步描述或解释其特定的信息。
首先，定语从句的引导词包括关系代词和关系副词。
常见的关系代词有：that, which, who, whom, whose，以及关系副词有：when, where, why。
关系代词在从句中除了作为主语或宾语使用外，还有时充当介词宾语，即用来修饰一个介词。
例如：The book that/which I borrowed from the library is very interesting.这个从句修饰先行词"book"，关系词"that/which"充当从句中的主语。
其次，定语从句有两种类型：限定性定语从句和非限定性定语从句。
限定性定语从句是先行词的必要信息，去掉它句子结构就不完整，从句不可省略。
而非限定性定语从句则是先行词的附加信息，对句子的主要内容并没有太大的影响，从句可省略。
例如：The girl who is sitting over there is my sister.（限定性定语从句）这个从句修饰先行词"girl"，限定了是"who is sitting over there"这个特定的女孩。
例如：Tom, whose mother is a doctor, is my best friend.（非限定性定语从句）这个从句修饰先行词"Tom"，是对Tom的附加说明，可省略。
此外，需要注意定语从句中的一些特殊情况和用法。
比如，当先行词是表示时间的名词时，定语从句中的关系副词可以使用"when"或"that"引导；当先行词是表示地点的名词时，定语从句中的关系副词可以使用"where"或"that"引导；当先行词是表示原因的名词时，定语从句中的关系副词可以使用"why"或"that"引导。

限制性定语从句通常使用关系代词和关系副词引导，关系代词在从句中作主语或宾语。
非限制性定语从句非限制性定语从句是对先行词进行补充说明，它对整个句子的意思并不具有限制作用，就算去掉也不会影响主句的表达。
非限制性定语从句通常使用逗号将其和主句隔开，关系代词在从句中作主语或宾语。
定语从句的位置定语从句可以放在先行词之后，也可以放在先行词之前。

此文档下载后即可编辑定语从句一、三个概念1.定语从句：2.先行词：3.关系词：先行词关系词定语从句先行词关系词二、关系词的用法关系代词: who/whom/that/which/whosewhose：表所有格，先行词既可以是人，也可以是物The worker whose arm was broken was sent to hospital.The river whose banks are covered with trees is very long.关系副词：when/where/why1. when: 指时间，其先行词表示时间，在句中作时间状语。
例：This was the time when he arrived.I will never forget the day when I met my favorite star.2. where指地点，其先行词表示地点，在句中作地点状语。
例：This is the factory where he works.Nanjing is the place where I was born.3. why 指原因，其先行词是原因，起原因状语作用。
例：Nobody knows the reason why he is often late for school.Is this the reason why he refused our offer?注意：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：I will never forget the day on which I met my favorite star.【when】Nanjing is the place in which I was born.【where】Is this the reason for whic h he refused our offer?【why】四、关系代词that的特殊用法只用that 的情况1.先行词被序数词或形容词最高级所修饰，或本身是序数词、基数词、形容词最高级时，只能用that，而不用which.例如：He was the first person that passed the exam.2.被修饰的先行词为all, any, much, many, everything, anything， none， the one等不定代词时，只能用that，而不用which.例如：Is there anything that you want to buy in the shop？3.先行词被the only， the very， the same， the last， little， few 等词修饰时，只能用that，而不用which.例如：This is the same bike that I lost.4.先行词里同时含有人或物时，只能用that，而不用which.例如：I can remember well the persons and some pictures that I saw in the room.5..以who或which引导的特殊疑问句，为避免重复，只能用that.例如：Who is the girl that is crying？6.主句是there be 结构，修饰主语的定语从句用that，而不用which.例如：There is a book on the desk that belongs to Tom.7.先行词在主句和从句中都作表语时，只能用that.例如：He is not the man that he once was.8.先行词是the way时，只用that不用that 的情况1.先行词为that, those时，用which，而不用that.例如：What’s that which is under the desk？2.关系代词前有介词时，一般用which，而不用that.例如：This is the room in which he lives. 这是他居住的房间。
3.引导非限制性定语从句，用which，而不用that.例如：Tom came back, which made us happy.五、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/关系副词。
例1. Is this museum ___ you visited a few days ago?A. whereB. thatC. on whichD. the one例2. Is this the museum ____ the exhibition was held.A. whereB. thatC. on whichD. the one答案：例1 D，例2 A。
例1变为肯定句： This museum is ___ you visited a few days ago.例2变为肯定句： This is the museum ___ the exhibition was held.在句1中，所缺部分为宾语，而where, that, on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D。
而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因in the museum词组，可用介词in + which 引导地点状语。
而此题中，介词on 用的不对，所以选A。
关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词（who, whom, that, which, whose）；先行词在从句中做状语时，应选择关系副词（ where 地点状语，when 时间状语，why 原因状语）。
非限制性定语从句非限定性定语从句的作用是对所修饰的成分作进一步说明，通常是引导词和先行词之间用逗号隔开，将从句拿掉后其他部分仍可成立。
但是限制性定语从句不能被省略，否则句意就不完整。
1.which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分2.当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：Charles Smith, who was my former teacher, retired last year.My house, which I bought last year, has got a lovely garden.This novel, which I have read three times, is very touching.3.非限制性定语从句还能将整个主句作为先行词，对其进行修饰，这时从句谓语动词要用第三人称单数，例如：He seems not to have grasped what I meant, which greatly upsets me.Liquid water changes to vapor, which is called evaporation.4.有时as也可用作关系代词5.在非限定性定语从句中，不能用关系副词why和关系代词that，而用who, whom代表人，用which, whose代表事物。
as, which引导的非限制性定语从句1.由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this 或and that。
As一般放在句首，which在句中。
As we know, smoking is harmful to one's health.The sun heats the earth, which is very important to us.2.as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。
但不同之处主要有两点：(1）as 引导的定语从句可置于句首，而which不可。
(2）as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which.。
(3) 当主句和从句存在逻辑上的因果关系时，常用which。
Tom was always late for school, which made his teacher angry.(4) as 的用法例the same… as；such…as 中的as 是一种固定结构, 和……一样……。
I have got into the same trouble as he (has).例2. as可引导非限制性从句，常带有'正如'。
As we know, smoking is harmful to one's health.As is known, smoking is harmful to one's health.As是关系代词。
例1中的as作know的宾语；例2中，它充当从句的主语，谓语动词know要用被动式。
定语从句的难点1.限制性定语从句只能用that的几种情况2.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，有相同之处也有不同之处。
