▶定语：

简单来说就是一个形容词，用来修饰名词或代词。e.g.deliciousfoodexcellentpolicebeautifulgirl▶定语从句：在主句中充当定语成分，同样起到形容词的作用，用来修饰名词或代词的句子。(在翻译的时候会出现“......的”)e.g.Thoseareoranges(thatIboughtforkids.)这些是我买给孩子们的橙子。定语从句，修饰其前面的名词oranges牛刀小试：把下列句子当中的定语和定语从句划下划线。1.PanZhanle(潘展乐)isayoungathlete.2.PanZhanleisanathletewhoswimsveryfast.Tips:位置：定语从句一般位于所修饰的____词或___词之后，故称作后置定语。二区：定语从句核心概念先行词：被定语从句修饰的词叫先行词。（名词代词）关系词：引导定语从句的词。（引导词）关系代词在句中的作用：连接作用、代替先行词、在从句中中充当成分▶关系代词用法总结关系代词指人/物关系代词充当成分thatwhichwhowhomwhose牛刀小试：把下列句子当中的先行词和关系词圈出来ThisisthegirlwhoteachesusEnglish.HeistheboywhomImetyesterday.Theclockisaninstrumentwhichcantelltime.Thisisthegirlwhosefatherisanengineer.（5）ThisisthebookthatIlostyesterday.三区：关系代词如何选择▶策略:1.确定先行词是指人还是物；2.定语从句缺什么成分？主语、宾语或者定语；3.对号入座，选择正确的关系代词。★观察并了解关系代词的用法Thebookthat/whichisonthedeskismine.
