语法精讲定语丛句语法精讲——定语从句 在复合句中，修饰某一名词或代词的从句叫定语从句。 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。 引导定语从句的词有关系代词 that, which, who（宾格 whom，所有格 whose）和关系副词 when, where, why. 关系代词或关系副词放在先行词和定语从句之间，起联系作用，同时又作定语从句的一个成分。一、关系代词的选择关系代词的选择，主要是指 that 和 who，that 和 which，as 和 which 这三对关系代词的选择。1．关系代词 that 的使用场合（1）一般说来，先行词是 all, anything, everything, nothing, much, little, few 等，关系代词应用 that。如： That's all(that) I know.
