英语语法,定语,同位语
同学们,定语从句中的非限制性定语从句里的解释先行词的 用法
和同位语从句 如何区别
英语语法,定语,同位语
你的问题是问that吗?非限中不用that的
限制性定语从句对先行词起修饰限制作用,而非限制性定语从句是对先行词起补充说明作用.非限制性定语从句中,先行词与定语从句往往有逗号隔开,非限制性定语从句相当于并列句、状语从句.
1)非限制性定语从句中的关系代词和用法:
指人 指物
主格 who which
宾格 whom which
属格 whose/of whom whose/of which
(that只用于限制性定从)
eg.He has two sons,who work in the same company.他有两个儿子,两个儿子在同一间公司上班.(意思是他只有两个儿子)
He has two sons who work in the same company.他有两个在同一个公司上班的儿子.(他可能还有别的儿子)
2)关系副词和用法:
当先行词在从句中作状语时,用关系副词:
when=表时间的介词(in,at,during etc.)+which
where=表地点的介词(in,at,on,under etc.)+which
why=表原因的介词(for)+which
how=表方式的介词(in,by)+which
3)从句中缺主语,宾语或表语时必须用关系代词(which,who,whom,whose,as),不缺成分用关系副词(where,when,why,how)
同位语从句是名词性从句的一种.
同位语从句用that(一般不省略),whether,特殊疑问词引导
that引导同位语从句在某些抽象名词之后,如fact,hope,desire,thought,suggestion,idea,news,problem,possibility,feeling etc.起补充说明作用,在从句中不作任何成分,不能省略
eg.There's a feeling in me that we'll never know what a UFO is.
我有一种预感,我们将永远不会知道UFO是什么.(用了that引导)
My question how I shall get in touch with him has not been answered.我如何能和他联系的问题没有得到答复.(用了特殊疑问词how引导)
The news that our football team won the match was encouraging.(用了that引导)
反正,非限中不用that(用which),同位语从句会用到that.
that引导定语从句时,在从句中作成分(主,宾,表),也就是说从句是不完整的.
that引导同位语从句时,在从句中不作成分,从句是完整的一个句子.
总之,看从句完整性就可区分.
eg.Shanghai is no longer the city that it used to be.(定语从句,that作表语)
This is the very person that i'm waiting for.(定语从句,that作宾语)
The news that our football team won the match was encouraging.(同位语从句,不作任何成分,our football team won the match 是完整的句子)
