定语从句的关系词引导定语的关系代词有：that, who (whom, whose), which; 关系副词（在定语从句中只能作状语，且不能省略）有：when, where, why等。关系词的选择主要取决于两个因素：(1)先行词是什么(2)先行词在定语从句中作什么成分。

①that/ who在从句中作主语，先行词为人。
Eg：The girl that/ who is reading is my sister.
②that/ which在从句中作主语或宾语，先行词为物。
Eg：The book that/ which is on the desk belongs to Tom.(主)
He came back for the book that/ which he had forgotten.（宾）
③whose在从句中作定语，先行词为人或物。
Eg：This is the pencil whose point is broken.
That is the girl whose mother died two years ago.
④whom/ that在从句中作宾语，先行词为人。
Eg：The girl whom/ that I spoke to is my cousin.
●关系副词（when/ where/ why）引导的定语从句。
①When在从句中作时间状语，其先行词是表示时间的词（day/ year/ season等）。
例如：我永远不会忘记我入团的那一天。I shall never forget the day______I joined the League.
解放军战士在人们最需要的时刻来到。
The PLA men come at the time ________ the people need them most.
②Where在定语从句中作地点状语，其先行词是表示地点的词（place/ town/ home/ house）
例如：你还记得我们初次见面的地方吗？Do you still remember the place ____we first met?
