E.g:He sent a message to me which said he was busy2.关系词: 引导定语从句的关联词称为...，关系词有关系代词和关系副词。
3.关系代词作用：①引导从句。
②代替主句中的先行词。
③在定语从句中充当一个句子成分,做宾语时可以省去。
4.关系代词: that（人/物）, which（物）, who（人）, whom(人,宾格), whose（所有格）, as等,没有what；关系代词在从句中作主语，宾语(可以省去)，表语，定语等.It is about a man who/that falls in love with a woman when he travels on a ship.The place that/which you were born in is San Francisco.The person who/that took him abroad when you?re young was his uncle.Is the piano you are playing bought at the high price?5.关系副词: where, when, why等。
