Question

物主代词有哪些？

Answer 1

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

人称代词的主格一般作主语，是动作的发出者。宾格是动作的承受者，作宾语。动词或介词的后面用宾格。
如： She often helps me.
He sent some flowers to her.

形容词性物主代词相当于是形容词，后面要跟名词；句词性的物主代词相当于名词，后面什么都不跟。
如： ---Whose is this book?
回答1： ---It's my book.
回答2： ---It's mine.
两种回答意思一样。
