从句中for which就等于Why吗?

从句中for which就等于Why吗? 在定语从句中Why为什么等于why=for which 不是Why＝for what 定语从句中什么时候用for which代替why why 和for which 在定语从句中一样么 名次性从句中for which 和why的区别 why 和 for which 替换的语法问题.定语从句中,why 和 for which 可以替换,在实际例句中,不太理解,如：1 Is this the reason why / for which he refused our offer 这就是他拒绝我们帮助他的理由吗?for which 这里,whic at which,in which,on which,for which,by which,from which的用法不要例句!要准确用在定语从句中等于什么! in which定语从句我想问下在定语从句中,in which是不是等于why啊?是不是有的时候不等于啊? 定语从句中,关系副词可以互相转化.when=on+which.where=in+which .why=for+which.这是如何转化的? why等于what for吗,什么时候等于for what在宾语从句中为什么why可以转换为for what 如：Do you know why he is late?这个句子的同义句是Do you know for what he is late,而不是Do you know what for he is late？ 在定语从句中which in,which on,which for,which怎么用? 定语从句do you know the reason why he didn't come?why为什么可以用For which代替用which的话后面一定要缺成分,而用why后面则不缺成分.两者不矛盾了吗? 定语从句中,关系副词有why吗?比如the reason why 结构,应该是可以理解成同位语的,而非关系定语.查过张道真的语法书,未提及关系副词why.但有for which结构,表达和why相似的意思.别光回答有还是没 定语从句中reason 后关系词的问题!先行词是reason ,后面关系词用why 还是 that 还是for which?有什么区别? 关于英语中的 非限制性定语从句he had committed a murder ,for which he got into trouble.这句是非限制性定语从句吧?非限制性定语从句,不是用which引导吗?前边加个介词也可以?再说 for which = why但是 why 不 Nobody knows the reason why he is often late for school.把why改成that/which引导的定语从句 定语从句关系副词why where when 分别等于什么which which,in which,on which,for which ,of which 有什么区别,在定语从句中怎么用
