26秋外研版九年级上册英语Unit4 单元语法 课件

这是一份26秋外研版九年级上册英语Unit4 单元语法 课件，共20页。
新外研版九上Unit4单词精讲who引导的定语从句2026一、概念用于修饰前面名词/代词的句子，就叫定语从句，简单说：从句用来修饰人或物，放在名词后面。二、基本结构先行词（人/物）+ 关系词（who/that/which）+ 从句本单元我们学习由who引导的定语从句。我们先来看两个例句:He's the boy who won the photo competition last year! 就去年赢得摄影比赛的那个男生!... thanks to everyone who entered the competition. .....感谢所有参加本次比赛的参赛者。句中红色部分为定语从句，分别用来进一步说明或限定它们前面的boy和everyone。我们称boy,everyone这些被定语从句修饰的词为先行词，who为定语从句的引导词，放在先行词及定语从句之间起连接作用，同时在定语从句中充当句子成分。从以上例句可以看出，如果先行词指人，那么定语从句的引导词就可以用who。两个例句里的who在从句中都充当主语。如果引导词在从句中充当宾语，那么引导词就要用who的宾格形式whom，口语中也可以用who代替。例如:I took some photos for the soldiers whom I met in the army. 我部队里碰到的战士们拍了一些照片。三、关系词who用法1. who：先行词是人，用who①（who 在从句中作主语，不可省略）The boy who helps me is kind.帮助我的那个男孩很善良。The young man who invented the new app

will star in a new movie.​我们非常敬佩的那位女演员将主演一部新电影。​I can’t find the friend who I made at the summer camp.我找不到在夏令营认识的那个朋友了。​一、单选题（选出最佳答案）。1.The girl ______ is standing at the door is my best friend.A. who
