在英语语法中,定语从句是一种常见的句子结构,用于修饰名词或代词。它通常由关系代词(如who, whom, whose, which, that)或关系副词(如where, when, why)引导,并且紧接在被修饰的名词之后。掌握定语从句的用法对于提高语言表达能力至关重要。本文将对定语从句的常见类型及其使用方法进行详细归纳。

- The book that/which I bought yesterday is very interesting.
2. which
- 用于指代事物,在从句中作主语或宾语。例如:
- This is the car which/that I rented last month.
- 注意:当先行词前有介词时,只能使用which。例如:

3. who 和 whom
- who用于指代人,在从句中作主语。例如:

关系词一般用that。例如:
