定语从句的基本用法

（一）定语从句的基本用法在复合句中，修饰名词或代词的从句叫做定语从句被修饰的词叫先行词；定语从句由关系代词或关系副词引导。关系代词：1.先行词是人—who,whom,whose,that.2.先行词是物—which,whose,that.关系副词（从句中做状语）：1.先行词是时间—when.2.先行词是地点—where.3.先行词是原因—why.例句1：Themanwho/thatwashereyesterdayisamiddleschoolteacher.1.先行词—man（即从句修饰的名词或代词）;2.关系代词—who/that（修饰人）。例句2：ThisisthetownwhereIwasborn.1.先行词—town（即从句修饰的名词）；2.关系副词—where（修饰地点，从句中状语）。

2.Thisistheplace_____weworkedlastyear.先行词“theplace”在从句中做状语，表示地点：Weworkedintheplacelastyear.(所以用关系副词where。)比较：Thisistheplace(_________)wevisitedlastyear.先行词“theplace”在从句中做visited的宾语：Wevisitedtheplacelastyear.(所以用关系代词which/that,并且可省略。)先行词在从句中做状语，用关系副词；先行词在从句中做宾语或主语，用关系代词。wherewhich/that注意
