【初中英语定语从句的讲解和例句】在初中英语学习中,定语从句是一个非常重要的语法知识点。它用来修饰名词或代词,使句子更加具体、清晰。掌握定语从句的结构和用法,有助于提高阅读理解和写作能力。
定语从句通常由关系代词(如 who, whom, whose, which, that)或关系副词(如 when, where, why)引导。在句子中,这些关系词既起到连接主句和从句的作用,又在从句中充当一定的成分。
一、定语从句的基本结构
定语从句的结构一般为:
主句 + 关系词 + 从句
其中,关系词在从句中担任一定的语法角色,比如主语、宾语、定语等。
二、常见关系代词和关系副词的用法
关系词 | 用法说明 | 在从句中的作用 | 举例 |
who | 指人,作主语 | 主语 | The boy who is standing there is my brother. |
whom | 指人,作宾语 | 宾语 | The teacher whom you met yesterday is very kind. |
whose | 表示所属关系 | 定语 | The girl whose bag was stolen is crying. |
which | 指物,作主语或宾语 | 主语/宾语 | The book which I bought yesterday is interesting. |
that | 指人或物,作主语或宾语 | 主语/宾语 | The man that is talking to the teacher is my father. |

why | 表原因,作状语 | 状语 | That’s the reason why he left early. |
三、使用定语从句的注意事项
1. 关系词不能省略:当关系词在从句中作宾语时,可以省略(如 The man (that) I saw),但在正式场合中建议保留。
2. 指人时可用 who 或 that,但指物时只能用 which 或 that。
3. 注意从句的语序:定语从句中的动词要放在主语之后,保持正常语序。
4. 避免重复:不要在主句和从句中重复使用相同的名词。
四、常见错误与纠正

The book which I lost it. | The book which I lost. | 不能同时用 which 和 it |
