名词性物主代词与反身代词的区别

Question

名词性物主代词： mine yours his/hers/its ours yours theirs

反身代词：
myself yourself yourselves herself himself
ourselves themselves itself oneself

我感觉名词性物主代词与反身代词差不多，请各位高手说明一下。

Answer 1

名词性物主代词可作主语、宾语和表语。例如
Ours is a socialist country.
You may use my pen and I will use hers.
This dictionary is mine.
名词性物主代词还可与OF连用，构成双重所有格。该结构常用于表示一定的感情色彩。
That gentlemen is a friend of mine.（部分概念）
This is no fault of yours.（感情色彩）

反身代词一是做宾语，表示动作的承受者是动作发出者本身
Take care of yourself.
一是做同位语，对名词或动词表示强调，也可做表语
She herself is a doctor.
