定语从句  什么是定语从句？ 用来充当定语的句子称为定语从句。 什么是定语？ Underline the attribute: a beautiful girl a fallen leaf a washing machine seven boys nothing difficult a boy behind me application form stone table （引导学生总结：用形容词、名词、过去分词、现在分词、介词短语、数词等修饰名词或者代词叫定语） 定语是用来修饰名词或代词的。形容词、代词、数词、名词、介词短语、不等式或相当于形容词的词或短 语等。 单个词作定语时，通常放在它所修饰的名词之前。 如：The black bike is mine. （形容词） What’s your name? （代词） They make paper flowers. （名词） 说明 1：当定语修饰不定代词 ：nothing, anything, everything, something 等时，定语在不定代词后面。 如：I tell him something interesting. （形容词 interesting 作不定代词 something 的后置定语） He has something to do. （to do 为不定式作后置定语） 说明 2 ：短语或从句作定语时，也放在被修饰的名词之后。 如：The boys in the room are in Class Four. （in the room 是介词短语作 the boys 的后置定语。） 定义 ：在复合句中充当定语的从句叫定语从句。 功能 ：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或代词或整个主句，所以，也称作形容 词性从句。 位置 ：定语从句结构：先行词+ 引导词+ 定语从句 概念 ： 先行词： 被定语从句修饰的词 定语从句：一般紧跟在它所修饰的先行词之后 引导词; ： 在先行词和定语从句之间起连接作用的词，有关系副词或关系代词 1.先行词（被定语从句所修饰，总是出现在定语从句的前面） This is the boy who/that won the first prize in the English Speech Competition. 简单句 This is a boy.
