he shi my she's he's yours hers his I my 有什么区别 比如make my min

he she it they I we you 是主格,在句子中只能做主语.he's=he is she's= she is和you are they are I am we are 一样是主语加系动词be.
your his her its my our their 是形容词性物主代词,相当于形容词,在句子中不能单独使用,其后必须加一个名词才完整.而加上名词后,就相当于名词性物主代词.
yours mine his hers its ours theirs 是名词性物主代词,等于名词的用法.因它等于形容词性物主代词加上名词.本身含有名词,所以make my mind 不能说成make mine mind.
