初中英语中,定语从句是一个非常重要的语法项目。定语从句通常用来修饰一个名词或代词,用于进一步说明或限定这个名词或代词的内容。定语从句的引导词有关系代词和关系副词两种。
关系代词有三个:who, whom, whose, which, that。关系代词在定语从句中充当主语、宾语或所有格。
关系代词who在定语从句中作主语,指人。例如:The boy who is sitting next to me is my best friend.(坐在我旁边的那个男孩是我的好朋友。)
关系代词whom在定语从句中作宾语,指人。例如:The girl whom I met yesterday is a famous singer.(我昨天遇到的那个女孩是一位著名的歌手。)
关系代词whose在定语从句中作所有格,指人或物。例如:The book whose cover is red is mine.(封面是红色的那本书是我的。)
关系代词which在定语从句中作主语、宾语或所有格,指物。例如:The cat which is sleeping on the sofa is very cute.(睡在沙发上的那只猫非常可爱。)
关系代词that在定语从句中作主语、宾语或所有格,指人或物。例如:The car that is parked outside is mine.(停在外面的那辆车是我的。)
关系副词有三个:when, where, why。关系副词在定语从句中充当状语。
关系副词when在定语从句中表示时间。例如:I still remember the day when we first met.(我仍然记得我们第一次见面的那一天。)
关系副词where在定语从句中表示地点。例如:This is the school where I study.(这是我上学的学校。)
关系副词why在定语从句中表示原因。例如:I don't know the reason why he left.(我不知道他离开的原因。)
在定语从句中,关系代词或关系副词引导的从句与先行词的关系紧密,不能随意改变。同时,当先行词是物时,可以用that来引导定语从句;当先行词是人时,可以用that或who来引导定语从句,但who更常用。
定语从句在句子中起到修饰作用,可以更加详细地描述名词或代词的特点或属性。掌握定语从句的语法规则和用法,能够帮助我们更准确地表达自己的意思,提高语言表达能力。初中英语定语从句是一个需要反复练习和巩固的语法项目,希望同学们能够多加练习,熟练掌握定语从句的用法。
