定语从句:在复合句中充当定语的从句叫定语从句。定语从句的作用相当于形容
词,
用来修饰主句中的某一名词、代词或整个主句,所以也称形容词性从句。
先行词:被定语从句修饰的词叫先行词,定语从句一般紧跟在它所修饰的先行词之后。
关系词
:在先行词和定语从句之间起连接作用的词叫关系词,分成关系代词和关系副
词:关系代词:who,
whom, whose, which, that, as 关系副词:when, where,
why
限制性定语从句与非限制性定语从句:
定语从句对先行词具有限制作用,使该词的
含义更明确,这种定语从句称为限制
性定语从句,这类从句不能省掉,否则句子的意义就不完整。限制性
定语从句与主句
之间不能用逗号隔开,修饰的是名词或代词,限制性定语从句中的关系代词在从句中作宾语时可以省略。
定语从句有时跟先行词的关系不十分密切,只是作一些附加说明,不起限制作
用,
这种从句称为非限制性定语从句,往往用逗号与主句分开。非限制性定语从句中的关
系代词
不可省略。
