她没在刚刚到达的那辆车上语法点拨什么是定语从句？修饰主语、宾语、表语的句子就叫做定语从句。

引导定语从句的关系词有：关系代词：who, whom, whose, which, that关系副词：when, where, why我们把下面两个句子组合成一个复合句：1. This is our school. It is beautiful.→This is our school which is beautiful.2. This is our school. We study in our school.→This is our school which we study in.→This is our school in which we study.→This is our school where we study.3. Do you know the room? It is made of amber.→Do you know the room which is made of amber?4. I have read the newspaper.

1. 全面掌握限制性和非限制性定语从句的区别。

2. 正确理解非限制性定语从句的引导词的作用及which, as的特别用法。

限制性和非限制性定语从句的区别1. The amber which was selected had a beautiful yellow—brown colour like honey.选出来的琥珀色彩艳丽，呈现蜂蜜一样的黄褐色。

2. It was also a treasure decorated with gold and jewels, which took the country’s best artists about ten years to make.它也是用金银珠宝装饰起来的珍品，一批国家最优秀的艺术家用了大约十年的时间才把它完成。

限制性定语从句是先行词在意义上不可缺少的定语，如果去掉，主句的意思就不完整或失去意义。

非限制性定语从句和主句的关系不十分密切，只是对先行词作些附加的说明，如果去掉，主句的意思仍然清楚。

（1）非限制性定语从句关系词的使用关系代词无论指人还是指物，都不能用that。

指人时，如果关系词作主语用who，作宾语用whom，指物时用which。

即使关系词作宾语也不能省略。

Mary, who is from Australia, is an old friend of mine.玛丽是我的一位老朋友，她来自澳大利亚。

非限制性定语从句关系代词和关系副词的选择方法和限制性定语从句一样，作主语和宾语时用关系代词，作状语时用关系副词。

He will put off the picnic until May 1st, when he will be free.他将把野餐推迟到5月1日，那时他将有空。

Section_ⅢGrammar—限制性定语从句和非限制性定语从句语法图解探究发现①This gift was the Amber Room,which was given this name because several tons of amber were used to make it.②The amber which was selected had a beautiful yellowbrown colour like honey.③However, the next King of Prussia, Frederick William Ⅰ，to whom the amber room belonged, decided not to keep it.④Later, Catherine Ⅱ had the Amber Room moved to a palace outside St Petersburg where she spent her summers.⑤This was a time when the two countries were at war.⑥There is no doubt that the boxes were then put on a train for Königsberg, which was at that time a German city on the Baltic Sea.[我的发现](1)例句①中含which引导的非限制性定语从句；例句②中含which引导的限制性定语从句；在形式上非限制性定语从句与限制性定语从句的区别在于：关系词前是否有逗号。

(2)以上例句中含非限制性定语从句的有①③⑥；含限制性定语从句的有②④⑤。

一、定语从句的种类根据定语从句与先行词之间关系的紧密程度，我们将定语从句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一、定语的概念：定语通常由形容词来担任，起限定和修饰名词或代词的作用。

① She is a beautiful girl.（beautiful是定语）二、定语从句的概念：由一个句子来担任定语的功能，相当于一个形容词，用来限定和修饰名词或代词。

① She is a girl who is beautiful.（who is beautiful这整个句子做定语）三、定语从句中的概念例：This is an old computer. It works much slower.（这是两个简单句，其中后一句中的it代替an old computer)→This is an old computer which/that works much slower.（这是一个复合句，which/that代替an old computer 引导定语从句）②The CD is very good. I bought the CD.→The CD that/which I bought is very good.③This is the house.We lived in the house two years ago.→This is the house where we lived two years ago.A.先行词：是被定语从句所修饰的名词或代词B.关系词：引导定语从句的词►关系词主要起三个作用：1.代替先行词2.在定语从句中作句子成分引导从句3.把从句和主句连接起来四、定语从句的分类：限制性定语从句和非限制性定语从句五、限制性定语从句与非限制性定语从句的区别：①形式不同：限制性定语从句紧跟先行词，与先行词之间一般不加逗号，仅修饰先行词。

非限制性定语从句仅作为补充或说明，用逗号与主句隔开，既可修饰先行词，又可修饰整个句子。

Eg:This is the house which we bought last month. （限制性）The house, which we bought last month, is very nice. （非限制性）②功能不同：限定性定语从句用于对先行词的意义进行修饰、限制和识别，如果去掉，就会造成句意不完整或概念不清。
