1、题目: 定语从句【学习目标】掌握定语从句的用法。【学习重点】that与which的区别；whose的用法；【学习难点】when, where, why与which, that的区别；介词+which, whom的用法；【知识链接】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
2、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。【学法指导】自主学习，理解并学会运用。【学习过程】一、关系代词：1. who指人，在定语从句中作主语。What was the
