1、先行词 关系代词 定语从句定语从句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：定语从句主要置于被修饰词之后Those who are willing to attend the party, sign here please.You told me to take anything that I wanted.The building which they are visiting was built last year.3、先行词：被定语从句修饰的词称为先行词antecedent1) The man who lives next to us is a policeman.

2、-先行词 关系代词 定语从句2) You must do everything that I do. - -先行词 关系代词 定语从句（1）先行词一般是名词和不定代词，如:some-, any-, every-和no与-body, -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。The old man whose son is in the army is my uncle.Pay attention to everything (that )I do.There are two who signed up

3、for(报名参加) it in my class.He ,who led theUnited States through these years ,was shot on April 14,1965.（2）先行词与关系词是等量关系。必须注意两点：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.These are the places which are worth visiting.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。There are many places

4、 that we can visit（them）in China.4、关系词：引导定语从句的词被称为关系词5、确定关系词的步骤（1）先找先行词，看先行词指的是什么。（2）看关系词在从句中所充当的成分。6、定语从句的种类（1）限定性定语从句：先行词和从句之间没有逗号隔开的This is the place which is worth visiting.（2）非限定性定语从句：先行词和从句之间有逗号隔开的He , who led the United States through these years ,was shot on April 14,1965.（3）限制性定语从句与非限制性定语从句
