Mary is a girl who has long hair.
先行词 关系代词
关系词
定语从句 关系副词 Where, when
which, who, whom, whose, that
关系词作用
1.代替先行词; 2.它还在定语从句中担任一定的成分; 3. 同时连接先行词与它引导的定语从句。 （把主句和从句连起来） 关系代词在定语从句中代替主句中的先行 词，所以它在一般情况下都跟在先行词之 后，而且它的 人称、数必须和先行词一致。
whose hair is white is his grandfather. 5. The man ______ whose 6. Is there a student _________ father is a business man? which 7. This is the house in ________ we have lived for 10 years. 8.I’ve never heard of the people and things ________ that you talked about just now.
