总结反思
一．定语从句先行词的特征：
1. 从句所修饰的词叫先行词。
2. 先行词可以放在从句缺少的成分里组成完整句子，或者从句完整时，先行词放在从句首作状语组成完整句子。
3. 从句一般紧挨着先行词，但是有时候先行词和定语从句会被单词或短语分割开，这时要找准先行词,从句修饰的名词就是先行词。
4. 先行词一般是个名词，但有时候也可以是个句子。
二．定语从句主从句的特征及划分：
1. 主句必须是完整的句子。
2. 关系词后边的第一个句子是从句。剩下的是主句。
3. 主句大部分情况在前面，有时候在后面，有时候被从句分割开。
4. 从句可以完整，也可以不完整。
三. 定语从句关系代词和关系副词的分类及选择。
■关系代词:that /who /whom /which/ as /whose 连接主从句并代替从句所缺成分。
■关系副词:where /why/ when 连接主从句不代替从句主干成分。
■从句完整时用关系副词，从句不完整时用关系代词。
