教材：九年级全一册 主题：定语从句之关系代词 自学提纲 什么是定语？ 定语是用来修饰名词或代词的形容词、短语或句子。 He is a tall boy. The book on the desk is mine. 什么是定语从句？ 定语从句必须放在所修饰词（即先行词）之后，由关连词（关系代词和关系副词）引导。 I like music that I can dance to. 定语从句的结构 I like music that I can dance to. 先行词 关系代词 修饰关系 先行词＋关系词＋从句 （名词） （连词） （句子） 解释什么是先行词，什么是关系代词 1. who/whom 二者皆可以指人，who在定语从句中做主语、宾语，whom只能做宾语。eg: (1)The boys are playing football are from Class One. (2) The man you met just now is my friend. who who/whom 2，that指，whowhom;物，相当于which。宾中主或者宾，做宾语时可省略。 注：若是介词后，指用whom， whicheg: 1] The people that/who come to visit the cityare all here. (句子中主 (2) Where is the man that/whom I saw thismorning?(在子中宾语) 2. that that 在定语从句中作关系代词时，可以指人也可以指物，可以做主语也可以做宾语。 注：若是介词后，指人用whom， 指物用which。 eg: (1)Do you know the man that/who is standing at the door?(指人在句子中做主语） (2) The lady that/whom /who he is talking to is his teacher. (指人在句子中做宾语) (3)The man to whom you just talked is Mr.Zhang.(to是介词) 3. which 指物，在定语从句中可以做主语也可以做宾语，做宾语时可以省略。 (1)Do you still remember the farm (which/that) we visited two months ago? （指物做宾语） (2) Football is a game which/that is liked by most boys.（指物做主语） 4.whose 通常指人，也可以指物，在定语从句中做定语，此时whose的意思是“......的”，后面要紧跟被修饰的名词。先行词和后面的名词之间往往是从属关系。 (1)I have a book whose cover is green. (2) He has a friend whose father is a doctor. 关系代词使用的特殊情况 1, 只用that不用which的情况 ①先行词为much， little， none， something，anything， all， the one等不定代词修饰时。〔当不定代词指人时只用who] ②先行词有序数词、数词、形容词最高级修饰。 ③先行词被the only， the very， the same，the last， just等词修饰。 ④先行词既有人，也有物。 eg: They talked about things and persons that they remembered. ⑤在以who/which 开头的特殊疑问句中. eg:Who is the person that is in red? ⑥在there,here 开头的句型中，指物只用that. 关系代词使用的注意事项 2.只用which不用that的情况 ①介词后面，先行词指物。 ②当先行词本身是that时。 eg: What’s that which is flying in the sky? B D that / B that A which / A that Homework 用刚刚所学的定语从句翻译句子 1.Tim 将要去观看在北京举办的2022冬奥会。 2.Jerry 喜欢2022东奥会的吉祥物冰墩墩（BingDwenDwen)。 3.你还能写出一些与冬奥会相关的定语从句吗？ Thanks for watching 制作：朱爽 $$
