1、Grade9 Unit6 I like music that I can dance to.语法教学： 定语从句 一、什么叫定语从句？在复合句中，修饰某一名词或代词的从句叫定语从句，被修饰的名词或代词叫先行词。定语从句一般放在先行词的后面。引导定语从句的词叫关系词，关系词放在先行词和定语从句之间，起联系作用。例如：1、 You said you couldnt understand people who talked fast.2、 I like music that I can dance to.上面两句中的people和music是定语从句所修饰的词，是先行词，定语从句放在先行词的后面。W
2、ho和that是关系词。二、关系词关系词分为关系代词和关系副词。关系代词有：who,whom,that,which等。关系副词有：where,when,why等。1、 who指人，在从句中作主语或宾语。（如前面有介词则用whom）。例如：The girl who is standing under the tree is my friend Emma.The man who/whom he wanted to see last week is in Shanghai.She is the girl with whom I went there.(指人代替先行词在定语从句中充当介宾且介词置于关系
3、代词之前)2、whom指人，在从句中作宾语。如：The man whom you just talked with is my father.3、 which指物，在从句中作主语或宾语。例如：These are the books which sell well.This bag (which) I bought yesterday is red.4、 that 既可以指人，也可指物，在从句中作主语或宾语，指人时相当于who 或whom,指物时相当于which.。例如：That woman that/who is in red is my aunt.The boy (that/who/whom
4、) you saw just now is from America.The skirt that /which suits me fine cost me 200 yuan.I have been to the city (that/which) you just visited.5、where 关系副词，在定语从句中作地点状语。如：The factory where I worked last year has changed a lot.。三、运用用who,whom,which,that 或where 填空。1、 There are many volunteers _are helpin
5、g poor children.2、 This is the pen_ my sister gave me for my birthday.3、 The man _ you met yesterday is my uncle.4、 I am looking for the pencil case_ I bought yesterday.5、 Beijing is the place_ I was born.四、注意事项：1、关系词在定语从句中作宾语时，常可省略。2、that,who,which在定语从句中作主语时，定语从句的谓语动词应与先行词保持一致。3、在定语从句中不能出现代替先行词的人称代词。4、定语从句中whose 的确定。无论先行词是人或物，在定语从句中作定语用whose。判断：看定语从句的主语前有无限定词（my,your,Jims等），若没有，则用whose。例如：The girl whose parents work in Beijing is Kate.I know the boy whose handwriting is very good.
