I 是主格,作主语。Me 是宾格,作句子(或介词)的宾语。My 是形容词性物主代词,作定语。Mine 是名词性物主代词,作主语、宾语或表语。例如:
I am a student. He and I are freinds. My mother looks after me. They know me. This is my book. That is mine. Mine is blue,yours is yellow.
注意 my 和 mine 的区别, 要表达“我的一个朋友”可以说:one of my freinds/a freind of mine/one freind of mine.
I后面只能跟am,me一般放在句子的中间,mine一般用于表示前一句所提到的事物,my是形容词性物主代词,后面只能跟名词.
