在英语语法中,定语从句是一种非常重要的句式结构,它能够帮助我们更清晰地表达信息并增强语言的表现力。而关系副词作为定语从句中的关键成分之一,在引导这类从句时扮演着不可替代的角色。本文将通过讲解和练习的形式,帮助大家更好地理解和掌握这一知识点。
一、什么是定语从句?
定语从句是用来修饰名词或代词的从句,通常位于被修饰成分之后。例如:“The book that I bought yesterday is very interesting.” 在这个句子中,“that I bought yesterday” 就是一个定语从句,用来修饰先行词 “the book”。
二、关系副词的作用
关系副词是用于连接主句与从句,并同时充当从句中某个成分的一种特殊词汇。常见的关系副词包括 where, when 和 why。它们分别表示地点、时间以及原因。
- where:指代地点,相当于 “in which”。例如:
- This is the park where we used to play football.
- when:指代时间,相当于 “on/in which”。例如:
- He will come back the day when he finishes his work.
- why:指代原因,相当于 “for which”。例如:
- That’s the reason why he was late for school.
