　　在*中，单独考察的题型几乎是没有的，但是语法知识点却贯穿整张试卷，下面频道为大家整理了英语六级基础语法知识，希望可以为大家带来帮助，一起来学习一下吧。 基础语法知识：定语从句
　　一、概念 定语从句的概念，在复合句中，修饰某一名词或代词的从句叫定语从句。

　　例如：
　　1) The man who lives next to us is a fool.
　　2) You must buy me the house which is near Xiangshan. 上面两句中的the man和the house是定语从句所修饰的词，叫先行词，定语从句放在先行词的后面。
　　二、关系词(连接词)
　　1.关系代词引导的定语从句 引导定语从句的关系词有关系代词：that, which, who (宾格whom, 所有格whose) 和关系副词where, when, why。关系词放在先行词和定语从句之间，起连接作用，同时还做定语从句的一个成分。
　　2.关于that, which的用法注意点
　　只能用that，不用which作为定语从句关系代词的情况 a)不定代词，如anything, nothing, the one, all, much, few, any, little等作先行词 There is nothing that I can do. I mean the one that was bought yesterday. b)先行词有the only, the very, the same, the last修饰 This is the very book that I want to find. The last place that I visited was the hospital. c)先行词为序数词、数词、形容词高级时 This is the first composition that he has written in English. d)先行词既有人，又有物时 He talked about the teachers and schools that he had visited.
