定语从句是在复合句中修饰某一名词或代词的从句。被修饰的名词或代词叫做选行词,
而引导定语从句的词叫引导词,有关系代词和关系副词两类。
懂得什么样的先行词后用什么样的引导词是学好定语从句的关键。
1. 关系代词有:that,which,who,whom,whose,在定语从句中作主语、宾语中表语,whose
作定语。代人的有:who,whom,whose,that;代物的有:that,which,whose.例如:
The man who helped you is Mr White.(who代人,在定语从句中作主语)
That is the person(whom/who/that) you want to see.(whom,who,that代人,在定
语从句中作宾语,可省略)
I´m not the fool(that) you thought me to be.(that代人,在定从中作表语)
A dictionary is a useful book which(=that)
tells us the meaning of words(which
或that代物,在定从中作主语)
