**高一英语定语从句简要介绍**
定语从句是用来修饰名词或代词的从句，常用关系代词或关系副词引导。常见的关系代词有 **who、whom、whose、which、that**，关系副词有 **where、when、why**。定语从句分为两类：
1. **限定性定语从句**（essential）提供必要信息，不用逗号。例如：*The book that I bought yesterday is interesting.*
2. **非限定性定语从句**（non‑essential）提供补充信息，用逗号隔开。例如：*The book, which I bought yesterday, is interesting.*
在句子中，关系代词通常放在从句的开头，指代先行词并在从句内部充当主语、宾语或其他成分。掌握这些基本规则后，学生就能在写作和口语中灵活使用定语从句，使表达更精准、生动。
