【初中英语定语从句的讲解和例句】在初中英语学习中,定语从句是一个重要的语法知识点,它用于修饰名词或代词,使句子更具体、清晰。掌握定语从句的结构和用法,有助于提高阅读理解能力和写作水平。
一、定语从句的基本概念
定语从句是指一个句子用来修饰另一个名词或代词,这个被修饰的词称为“先行词”。定语从句通常由关系代词或关系副词引导,如 who, whom, whose, that, which, when, where, why 等。
- 关系代词:who(指人)、whom(指人)、whose(指人或物)、that(指人或物)、which(指物)
- 关系副词:when(时间)、where(地点)、why(原因)
二、定语从句的结构
定语从句一般位于先行词之后,结构为:
先行词 + 关系词 + 从句
例如:
- The book that I bought yesterday is very interesting.
(我昨天买的那本书很有趣。)
三、定语从句的分类与用法
| 类别 | 关系词 | 用法说明 | 例句 |
| 1. 指人 | who | 在从句中作主语 | The boy who is standing there is my brother. |
| 2. 指人 | whom | 在从句中作宾语 | The girl whom you met yesterday is my classmate. |
| 3. 指人或物 | that | 可指人或物,常用于限制性定语从句 | The man that came to the door is my teacher. |
