江苏省上冈高级中学 2010 届高三英语语法复习系列(一) 定 语 从 句 一、定语从句的基本概念和基本用法在主从复合句中，用来修饰某一名词或代词的从句叫定语从句。被定语从句所修饰的词叫先行词。引导定语从句的词有关系代词和关系副词。关系代词有：that, which, who, whom, whose, as；关系副词有：when, where, why。二、定语从句高考考点【考点 1 】关系代词和关系副词的选用关系代词代替的先行词是表示人或物的名词或代词，在从句中充当主、宾、定语等成分。关系副词引导定语从句时，可在从句中作状语，分别表示时间、地点或原因。因此定语从句中关系代词和关系副词的选用关键是看从句的成分是否完整，如果从句里缺少主语、宾语或定语时就该选用关系代词，如果不缺少主要成分就选用关系副词。【高考链接】1. —Where did you get to know her?—It was on the farm_____ we worked.
