定语从句解题步骤： 第一,找出先行词； 第二,看先行词在从句中的成分 (做主语、宾语、定语还是状语 ?） 第三,选择合适的关系词 ;一、定语从句的定义： 用来修饰名词或代词的从句叫定语从句。被定语从句所修饰的名词或代词叫先行词。定语从句一般是由关系代词或关系副词来引导的。相当于名词和形容词的作用。 eg: 1. Do you know the man who came to see Xiao Yang this morning? 2.The day is not far off when we will make a trip to Britain.;二、关系代词和关系副词的作用： 1、引导作用 2、替代作用 3、在定语从句中担当某个成分的作用 eg: 1.Those who want to go please sign your names here. 2.This is the house where he was born. 3. Bill, who was here yesterday, asked me a lot of questions.;三、关系代词（who, whom, which, that, whose）的指代关系;Eg:1.He is such a man who never tells a lie. 2. He is the model worker whom/who we should learn from. 3. A dictionary is a book which often helps us to know the meanings of the words. 4. This is the film which I like best. 5. The boy whose father is a professor is one of my best friends. 6. The house whose roof was blown away by the storm will be rebuilt soon.;四、关系代词which和that的区别： A.关系代词必须用that的情形： 1、当先行词被形容词的最高级所修饰 This is the best film that I have ever seen. 2、当先行词被序数词修饰 The first car that arrived at the destination was driven by John. 3、当先行词被the only, the very等修饰 This is the only ticket that I got yesterday. This is the very book that I’m looking for.;;五、关系副词when, where, why的用法;六、as引导定语从句，多与such和the same连用，在从句中作主语或宾语。;;2、关系代词放在介词后面，只能用which或whom a.This is the boy with whom he worked. b.This is the boy whom he worked with. c. This is the boy who he worked with. d. This is the boy he worked with. e. The house where we live is not large. f. The house in which we live is not large. g. The house which we live in is not large. h. The house we live in is not large. ;限制性定语从句和非限制性定语从句; 八、限制性定语从句和非限制性定语从句 ;2．非限制性定语从句和主句关系不十分密切，只是对先行词作些???加的说明, 如果去掉, 主句的意思仍然清楚。这种从句和主句之间往往用逗号分开，一般不用that引导。非限制性定语从句中，关系词不可省略。如： a) Yesterday I met Professor King, who came from the University of London. 昨天我遇见金教授，他从伦敦大学来的。 b) He lent me a dictionary, which was just what I needed. 他借给我一本词典，这正是我所需要的。 ;3.大多数
