在中考英语中,定语从句是一个非常重要的语法知识点。它能够帮助我们更清晰地表达句子中的修饰关系,使语言更加精确和生动。本文将围绕定语从句的基本概念、结构特点以及常见考点进行详细解析。
一、什么是定语从句?
定语从句是用来修饰名词或代词的从句。它通常位于被修饰词之后,并对这个名词或代词起补充说明的作用。例如:
- 原句:The book that I bought yesterday is very interesting.
- 分析:在这个句子中,“that I bought yesterday” 是一个定语从句,用来修饰先行词“book”。
二、定语从句的构成
定语从句由两部分组成:
1. 先行词:即被修饰的名词或代词。
2. 关系词:连接主句与从句的关系代词或关系副词。
关系代词
常见的关系代词有:
- who(指人):The man who is talking to the teacher is my father.
- whom(指人,在宾格位置使用):The woman whom you met just now is my aunt.
- which(指物):The car which he drives every day is black.
- that(既可指人也可指物):The book that I borrowed from the library is very useful.
关系副词
常见的关系副词有:
- where(指地点):This is the place where we first met.
- when(指时间):That was the time when I decided to study abroad.
- why(指原因):This is the reason why he didn’t come to the party.
三、定语从句的常见考点
在中考英语中,定语从句的考查主要集中在以下几个方面:
1. 选择合适的关系词
- 根据先行词的不同,选择适当的关系代词或关系副词。例如:
- 先行词是人时,优先考虑使用“who”或“whom”;
- 先行词是物时,优先考虑使用“which”或“that”;
- 先行词表示地点、时间或原因时,则分别使用“where”、“when”或“why”。
2. 判断是否省略关系词
- 当关系词在从句中作宾语时,可以省略。例如:
- 原句:The boy (whom) I saw yesterday is my classmate.
- 省略后:The boy I saw yesterday is my classmate.
3. 区分关系代词和关系副词
- 需要根据句子的具体含义来确定使用哪种关系词。例如:
- 正确:This is the factory where they produce cars.
- 错误:This is the factory which they produce cars.
