4.引导非限制性定语从句时as与which的区别
关系词

还可插入主句中
mention，report等
which 通常放在主句之后
意为“这一点”或“这件事”等

2.位置：定语从句置于被修饰词之后。
Those who are for the plan raise your hands，please.3.先行词：被定语从句修饰的词称为先行词。

高考高中英语核心语法详解 定语从句
高考高中英语核心语法详解定语从句关系从句//定语从句一、基础知识1. 由来：两个句子之间要有一个重复元素产生关联。
重复点上改写为关系词，由此产生关系从句。
这个重复点在主要从句中称为先行词（antecedent）。
在关系从句中称为关系词，分为关系代词和关系副词。
结构一般比较固定：先行词+关系词+从句例：The boss lives opposite my house. 那位老板住在我家对面。
He is very rich. 他很富有。
说明：the boss 和he 为重复点；下面保留boss，把he改写为who，组成一句话：The boss who lives opposite my house is very rich. 住在我家对面的那位老板很富有。
boss称为为先行词；who为关系引导词；who引导的句子称为关系从句或定语从句。
2.内涵:忌重复原则决定，目的让句子更紧凑；尾重原则，决定重点信息后置。
3.先行词：被关系从句所修饰的词The tall man who is standing over there is my uncle. 正站在那儿的高个子男士是我叔叔。
man为先行词。
4. 关系词：让两个句子产生关联；具有双重角色；（1）角色一：代替前面的先行词；（2）角色二：起到连接作用，并在其引导的句子中承担相应语法成分；例：This is the book that I bought yesterday. 这是我昨天买的那本书。
that代替前面的先行词book; that同时是其引导句子中bought的宾语。
5. 限制性定语从句与非限制性定语从句区分口诀: 有无逗号；限定不限定；展开不展开；a. 限制性: 从句紧跟先行词，两者之间无逗号，并且句意特别指定先行词，并不展开。
b.非限制性：先行词与从句中间用逗号隔开;句意非特指不限定，从句继续展开。
例：限制性There is a tribe of busy little people who live in the Frozen Zone.一个忙碌的小人部落住在冰冻区。
高考英语语法复习之限制性定语从句和非限制性定语讲义
高中英语语法复习之限制性定语从句和非限制性定语定义和用法在英语语法中，定语从句是用来修饰名词或代词的句子成分，通常分为限制性定语从句和非限制性定语从句两种。
限制性定语从句和非限制性定语从句是英语语法中两个重要的概念。
限制性定语从句是指用来修饰一个名词或代词的从句，这个从句在句子中充当定语的作用，对名词或代词起限定、说明的作用。
与之相反，非限制性定语从句通常用来进一步说明被修饰的名词或代词，起到补充说明的作用，它不能充当主语、宾语等成分，并且通常可以被省略。
限制性定语从句通常由that、which、who、whom、whose等引导词引导，也可以由as、when、where、why等引导词引导。
限制性定语从句通常与主句之间需要用逗号隔开，而且通常放在主句之后。
例如:The book, which I read last week, is really interesting.(限制性定语从句)The man, who is a doctor, can help you.(限制性定语从句)非限制性定语从句则没有这些限制，它可以充当主语、宾语、表语、定语等成分，并且通常可以被省略。
非限制性定语从句通常由that、which、who、whom、whose等引导词引导，也可以用as、when、where、why等引导词引导。
例如:The book, that I read last week, is really interesting.(非限制性定语从句)The man, who is a doctor, can help you.(非限制性定语从句)需要注意的是，非限制性定语从句和限制性定语从句在句子中的作用不同，因此需要根据具体情况来选择合适的定语从句类型。
限制性定语从句是先行词在定语从句中充当主语或宾语，对先行词起修饰和限制作用，二者缺一不可。
限制性定语从句和非限制性定语从句是英语语法中的两个重要概念。

高考英语语法之从句讲义：定语从句精讲
充当定语的句子叫定语从句。
定语从句修饰的名词叫先行词(the antecedent).
定语从句由关系代词: who, whom, which, 关系形容词whose 和关系副词when, where, why引导，关系词除了起连接从句和名词的作用外，还作从句的句子成分。
1.限制性定语从句
Who的先行词是人，作定语从句的主语：
This is the man who will give us a talk tomorrow.
Whom的先行词是人，作定语从句的宾语：
This is the man whom I talked about the other day.
Which 的先行词是物，作从句的主语和宾语
Here is a book which may be helpful in you English study.
This is the book which I like best.
上述例句都可改用that.
Whose是个关系形容词，在从句中作定语。

When, where, why 分别作从句的时间状语、地点状语和原因状语。
He will never forget the day when the accident took place.
This was the room where we studied.
Do you know the reason why he was late?
2.非限定性定语从句：
非限定性定语从句所修饰的先行词可以是名词（许多是专有名词），也可以是整个主句，它对先行词不加限定，只起附加说明作用，如果没有，也不影响句意和语法结构。
非限定性定语从句和先行词书写时有逗号断开。
Yesterday I happened to see John, who was eager to have a talk with you.
She was late again, which was annoying.
区分限定性定语从句和非限定性定语从句很重要。
He has a sister, who is an artist.
他有个妹妹，是个艺术家。
（只有一个）
He has a sister who is an artist.
他有个当艺术家的妹妹。
（还有别的）
在such…as…, the same…as…的固定搭配中，such作定语，修饰后面的名词，as是个关系代词，代前面的名词，引出定语从句，并担任从句中的句子成分。
We will give you such data as will help you in your work.
I would like to use the same instrument as was used yesterday.
as也可以用作关系副词，代替前面的状语，并作从句的状语。
He answered with the same simplicity as she asked.
在as many …as的固定搭配中，第一个as是副词，修饰many，第二个as是关系代词，引导定语从句，并作从句的主语或宾语。
There are as many books as are needed.
所需要的书都有了.
He has as many books as I have.
他的书和我的一样多。
As everyone knows, all that glisters is not gold.
上句中as everyone knows 在意义上是个状语，但在句子结构上却是个非限定性定语从句。
As是关系代词，指代整个主句，引导定语从句，并作knows的宾语。
As is often the case, we have over fulfilled the production plan.
和往常一样，我们又超额完成了生产计划。
（as作从句的主语）
非限制性定语从句不能用that引导，引导非限制性定语从句的关系词不能省略。
用that的场合
1) 当先行词既包括人又包括物时
He talked about the men and the books that attracted him.
2) 先行词被any, every, only, very, all, no 修饰

(3) 先行词被序数词或形容词最高级修饰

(4) 先行词是指物的不定代词all, little, few, much,及everything, anything, nothing There is still much that can be done about it

2）介词放在关系代词之前
This is the man from whom I learnt the news.
3）句中出现了that，或先行词是that
I have found that which I was looking for.
“介词＋关系代词”用法
(1) 介词的确定应依据定语从句中短语的习惯性搭配：
Who is the girl with whom you just shook hands (shake hands with…是习惯性搭配(2) 介词和先行词的搭配
He built a telescope through which he could study the skies. (through which 即through the telescope)
(3) 当关系代词作“动词＋介词”固定短语的宾语时，此时固定短语中的介词不能拆开移到关系代词前。
This is the watch which you're looking for
特殊情况
(1) Situation后常用where, in which引导定语
从句
Can you imagine a situation where/in which you can use the word?
(2) way(方式，方法)后常用in which或that或how引导定语从句，也可省略Do you know the way (in which /that /how) he worked out the problem?
