定语从句
在复合句中修饰名词或代词的从句是定语从句。被定语从句修饰的词叫先行词。定语从句必须放在先行词的后面。定语从句一般由关系代词that, which, who, whom, whose和关系副词when, where, why引出。
关系代词和关系副词有两个作用：1、把主句和从句连接起来;2、在从句中作一个成分。which, that, who在从句中作主语或宾语;whom作宾语;whose作定语。when, where, why在从句中作状语。
关系代词that, which, who, whom如果在从句中作宾语，也可以省略。
另外，如果which或whom在定语从句中原为介词的宾语，则这个介词可以提到从句前，构成介词+which或whom引出的定语从句。
定语从句根据与先行词的密切程度可分为限制性定语从句和非限制性定语从句。限制性定语从句与先行词关系密切，从句是整个句子不可缺少的部分，去掉之后句子的意思就不完整，不明确，从句与主句之间不用逗号隔开。非限制性定语从句与先行词的关系比较松散，从句只是对先行词的附加说明，去掉之后句子的意思仍然很清楚，从句与主句之间常用逗号隔开。
