he his his him 呢類嘢點用

He, I (Subject Pronoun/主格代名詞)
e.g. He goes to school everyday.
I go to school everyday.

him, me (Object Pronoun/受格代名詞/被動者)
e.g. I met him yesterday.
Please give me that book.

his, my (Possessive Adjective / 擁有形容詞)---跟著一定有個(noun)名詞
e.g. His house is very big.
My dog is very small.

his, mine(Possessive Pronoun / 擁有代名詞)---後面不用跟有(noun)名詞
e.g. His house is very big but mine is very small. (mine = my house)
My dog is very small and his is very big, too.(his = his dog)

I and he 是人称代词，用作动词的主体。
my,his 就是我的、他的这样咯！
mine, him 人称代词，用作动词或介词的宾语，亦可单独使用或用于be之后.
