The children who/that live on the nearly farms ride to school. 2、作宾语用 whom, who, which, that, 如： The man(whom/who/that/)we have just seen is a famous writer. The letter(which/that) I received from him yesterday is very important. 3、作定语用 whose, 如： They came to a house whose back wall (= the back wall of which)had broken down. I know the man whose company (=the company of whom)produces computers. 4、作表语只用 that，它既可以指人，也可以指物，但时常省略。例如： This is no longer the dirty place (that) it used to be. 5、as 引导限制性定语从句，指代被 the same, such, as, so 修饰的名词。 (a) Don’t talk about such things as you don’t understand. (b) Here is so big a stone as no one can lift. (c) The city isn’t the same as it used to be 6、the way 表示方式时，其后的定语从句有以下几种情况
Can you tell me the way that/ in which/～you solve the problem. 要点二： 下列情况下, 一般用 that 而不用 which 1、先行词为 all, everything, nothing, something, anything, little, much 等不定代 词以及先行词被这些词修饰时。 I am sure she has something (that) you can borrow. 2、 先行词被 all, every, no, some, any, little, much, the only, the very, the same, the last 等修饰时。 I’ve read all the books that are not mine. 3、先行词被序数词或最高级修饰时。 This is the first book (that) he has read. 4、先行词是 who 或 who 引导的主句。 Who that broke the window will be punished. 5、当先行词在定语从句中作 be 表语時，关系代词用 that。 She isn’t the girl that she was 10 years ago. 6、当先行词是 which 时，关系代词用 that. Which is the book that you bought last week? 【课内探究】 I. 难点思考 1.关系代词三大作用：__________，_____________，______________。 2.区分：①. whose sweaters are these? (whose 在这里是____代词，意思是_________，充当_______ 语) ②.
