定义: 在复合句中起定语作用，修饰名词、代词、整个主句或主句中的一部分的从句。
类型: 限制性定语从句（描述主句所涉及的人或物的具体情况，是主句不可缺少的一部分；如省去，主句意义不完整或失去意义）。 关系代词：that, which, wh, whm, whse等。引导定语从句的关系代词有三个作用：1) 连接作用：引导从句，把从句和它所修饰 的内容连接起来；2) 替代作用：在从句中替代被从句所修饰的 先行词；3) 在从句中充当成分：作主语、宾语、表 语、定语。
关系代词的用法与辨析1) 关系代词that与which 定语从句中, 关系代词that既可指人也可指物，which一般用于指物。指物时二者一般可以互换。只用that引导定语从句的情况：① 当先行词为all, everything, anything, nthing, much, little, nne等不定代词或先行词被the nly, few, little, n, all, every, the very等词修 饰时。
② 当先行词同时包括人和物时。如： They talked abut the teachers and schls that they had visited.③ 当先行词前有序数词first, last, next等或形容 词的最高级修饰时。如： This is the first article that I’ve written in Japanese.④ 当主句是由wh或which开头的疑问句时。 如： Wh is the man that is standing by Jack?
2) 关系代词wh与whm wh指人，主格，在定语从句中作主语，一般可用that替换。 whm指人，宾格，在定语从句中作宾语。在口语和非正式文体中可用wh或that替换，也可以省略。3) 关系代词whse whse是wh的所有格，在定语从句中作定语，起限定作用。whse引导定语从句时，先行词可以指人也可以指物。
