中考英语 定语从句讲解

定语从句 ‎ 请看下面的句子：‎ ‎ I want to know the boy who is the tallest.‎ ‎ ‎ 句子做定语修饰boy ‎（一）概念:‎ 定语从句：在复合句中修饰名词或代词的句子， 叫定语从句。‎ 先行词：被定语从句修饰的词叫先行词。‎ 关系词：引导定语从句的词叫关系词。‎ （二） 定语从句的分类 Ⅰ、限定性定语从句：从句不可少，没有它，先行词的意思不明确，主句也不完整。与先行词之间不用逗号。‎ e.g:This is the book that/which I want.‎ Ⅱ、非限定性定语从句：是对先行词的补充说明，没有它不会影响先行词或主句意思的完整性。 从句一般用逗号同主句分开。‎ e.g:Mr. Green， who is watching TV，is my uncle.‎ ‎（三）(限定性)定语从句的结构 Mary is a girl who has long hair.‎ 先行词 关系词 定语从句 关系代词 关系副词 ‎ ‎ which, who, whom,‎ ‎ whose, that where, when, why ‎（四）定语从句的实质：二句合一 ‎（合并条件：人物先行在句一，又占句二一席地）‎ Mary is a girl.‎ ‎ 合并为一个句子 She has long hair.‎ 思路：留（保留先行词）-----舍（舍去与先行词互指的词）----替（用关系词代替舍去部分）‎ Mary is a girl who/that has long hair.‎ 请把下列句子二句合一 ‎ 1. I saw the man.He closed the door ‎ ‎ ‎ 2.The girl is happy. She won the race ‎ ‎ ‎ 3.The man called the police . His wallet was stolen ‎ ‎ ‎（五） 定语从句关系词的确定:‎ l a.先行词的分类 l b.先行词在从句中充当的成分 ‎1.先行词做主语 人：who/that ‎ 物：which/that ‎2.先行词做宾语 人：who/whom/that ‎ 物：which/that ‎3.先行词做定语 人：whose ‎ 物：whose/of which ‎4.先行词做状语：when, where, why l who, whom, whose, that用法区别.‎ l who /that作定语从句的主语或宾语.‎ ‎ The man who/that is speaking at the meeting is a worker.‎ ‎ 做题思路：先分解——分析——再合并 分解 The man is a worker.‎ ‎ The man is speaking at the meeting.‎ ‎ 作主语 l Whom /that作定语从句的宾语 ‎ The woman（ whom/that) they wanted to visit is a teacher.‎ 分解 The woman is a teacher.‎ ‎ They wanted to visit the woman.‎ ‎ 作宾语 注意: 关系代词作动词宾语时可省略.‎ l whose 作定语从句的定语.‎ ‎ I know the girl whose mother is a teacher.‎ 分解 I know the girl.‎ ‎ The girl’s mother is a teacher.‎ ‎ 作定语 小结：‎ 关系词判断步骤 l 首先，要辨别出先行词。如果先行词是指人,关系词可能就用who, that whom, whose。如果先行词指物,关系词可能用which或that l 然后，要确定关系词在从句中的成分。请看下表 先行词 ‎ 主语 ‎ 宾语 ‎ 定语 ‎ 人 who, that who(m), that ‎ whose ‎ 物 ‎ which,‎ ‎ that which, that ‎ whose, ‎ ‎ of which 巩固练习：用适当代关系词填空 ‎1.

Here is something that I will tell you.‎ ‎2.We haven’t got much that we can offer you.‎ ‎3. Is it the one that you want ?‎ ‎4.This is the most interesting story that I have ever heard.‎ ‎5.
