Who can give me the reason for which he hasnt turned up yet?Who can give me the reason why he hasnt turned up yet?关系副词都等于一个适当的介词which,在从句中作状语1. when 在定语从句中作时间状语,相当于“介词+ 关系代词(which) ”。Ill never forget the day when I joined the league.= Ill never forget the day on which I joined the league.2. where 在定语从句中作地点状语,相当于“介词+ 关系代词(which) ”。This is the house where I lived two years ago.= This is the house in which I lived two years ago.3. why 在定语从句中作原因状语,相当于“介词 for+ 关系代词(which) ”。Do you know the reason why she was late?= Do you know the reason for which she was late.when=in/at/on/+which;where=in/at/on/+which;why=for /+which注:区分关系副词与关系代词的区别。只要在定语从句中担任状语的,就是关系副词注:区分关系副词与关系代词的区别。只要在定语从句中担任状语的,就是关系副词。你还记得我们一起去参观博物馆的那一天吗?Do you still remember the day when (on which) we went to visit the museum together?这是我父亲曾经工作过的工厂。This is the factory where (in which) my father once worked.这就是他愤怒的理由。This is the reason why (for which) he was angry.关系副词引导的定语从句作用:1、在定语从句中替代先行词。2、在从句中担任状语成分,起副词和介词短语的作用。3、起连接作用,把两个句子连接成为一个带有定语从句的主从复合句。关系词关系词Who人主/宾Whom人宾Which物主/宾关系代词That人或物主/宾/表Whose人或物定语Where地点When时间关系副词 Why原因状语【典型例题典型例题】1、The continent _ I visited last year was not the one _ I once worked.A. which; where B. which; which C. where; which D. where; where答案:答案:A 这里有两个定语从句,第一个是_ I visited last year,先行词为continent,这里缺少关系词,关系词在从句中做宾语,所以用 which;第二个定语从句是_ I once worked,这里的关系词在从句中做状语而不是宾语,因为我们不能说 I worked the one(the continent),所以用 where。所以选 A。【模拟试题模拟试题】 (答题时间
