【初中定语从句讲解练习及答案_百度文库(12页)】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。它不仅在考试中频繁出现，也是提升语言表达能力的关键内容之一。掌握好定语从句的用法，能够帮助学生更准确地理解和运用复杂的句子结构。
定语从句的作用是修饰名词或代词，用来提供更多的信息。在句子中，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。这些关系词在从句中充当一定的成分，比如主语、宾语、定语等。
例如：
- The book that is on the table is mine.（那本在桌子上的书是我的。）
在这个句子中，“that is on the table”是一个定语从句，修饰“the book”。
再如：
- The man who is standing there is my teacher.（站在那里的那个人是我的老师。）
这里，“who is standing there”是定语从句，修饰“the man”。
