主格宾格物主代词反身代词怎么用啊,很容易就搞混啦

主格----I you he she it wu you they (主格放在句首做主语)

物主代词分为形容词性物主代词和名词性物主代词
形容词性物主代词-------my your his her its our your their (用来修饰名词)
如:My pen is red.(我的钢笔是红色的)
名词性物主代词--------mine yours his hers its ours yours theirs (省略名词时用名词性物主代词 )
如:--May I borrow your pen(我能借一下你的钢笔吗?)

反身代词---myself yourself himself herself itself ourselves yourselves themselves(用来指某人自己)
