关系副词的作用
①连接：连接定语从句和主句
②替代：关系副词=介词+which=介词+先行词
③成分：在定语从句中作状语
关系副词 先行词 充当从句的成分
when 表时间的名词 （time, moment, day, month, year, period等） 时间状语
where 表地点的名词 （place, house, city, country, world等） 地点状语
why reason 原因状语

Rules:
关系代词和关系副词的正确运用：
要想为定语从句确定一个关系词，首先要找出被定语从句修饰的_________，然后再分析定语从句的成分。若定语从句中缺少主语、宾语、表语或定语，则选用____________。若定语从句中不缺主语、宾语、表语或定语，或不需要宾语（谓语动词为不及物动词），则选用____________。
注意：如果定语从句中不缺状语而缺乏的是主语或宾语，即使先行词是时间（如day）、地点（如school）、原因（如reason），连接定语从句也不能用关系副词。
