我 你 他 她 它 我们 你们 他们
主格：I you he she it we you they
宾格：me you him her it us you them
形容词性
物主代词：my your his her its our your their
名词性
物主代词：mine yours his hers its ours yours theirs
反身代词：myself yourself himself herself itself ourselves yourselves themselves
注：主格做主语,动词前 (She ) likes studying.
宾格做宾语,动词介词后 Listen to (him)
所以形容词性物主代词通常被叫做所有格,修饰名词,不能单独使用 （Her）bag is blue.
名词性物主代词,单独使用 = 所有格+名词 This is (my bag)=This is mine
