Question

定语从句修饰物用which that,它们两有什么区别,如I've given you everything I hav？

Answer 1

1.在非限制性定语从句中只可用which,不可用that.
2.which 只能指代人；that可以指代人,也可指代物
3.如果出现what,要看它在从句中作什么成分,并且还要看主句缺少什么成分.eg:I don't know what he has done.这个句子what he has done就是个宾语从句,应为主句I don't know 缺少宾语.,10,前面有介词的就只能用that 不能用which,1,which是修饰人的，有特指的意思。而that既可修饰人，也可修饰物，在有些句中可省略。,0,你主要看先行词在句中起什么成分，然后再选用恰当的连接词,0,what既在从句中作成分，又在主句中作成分。而that和which只能在从句中作成分。而which前可用介词，如to which ,for which 等。
例：
i don't understand what you said.（此处what兼作主句和从句的成分）
i don't understand the words that you said.（此处words作主句...,0,定语从句修饰物用which that,它们两有什么区别,如I've given you everything I have.that ；which
还有 有时候 选择题中回出现WHAT 引导的从句 ,然后就会觉得既是定语从句又是其他的从句,怎么办呢?
