I 主格人称代词 :主格一般用在句子开头做主语.通常用在动词前. e.g. I am a teacher.my 形容词性物主代词 :形代后面一般要带上名词. e.g. my watch my wife .......me 宾格人称代词 :宾代是用来接受动作的对象,一般用在动词和介词的后面. e.g. follow me .mine 名词性物主代理: 名物本身就是名词,后面不能跟名词,可单独使用. e.g. Is this your car? No,mine is red. (mine = My car)
这要看在句中作什么成分,如果是作主语,应该是 and I,如:my father ,my mother and I like oranges.如果是作宾语,应该是是 and me,如:There are three people in my family——my father ,my mother and me.
