物主代词在英语中表示所有关系的代词叫做物主代词。物主代词分形容词性物主代词和名词性物主代词二种。形容词性物主代词(my/your/his/her/its/our/their)后面必须跟名词。而名词性物主代词则相当于形容词性物主代词 名词,因此后不必加名词。
Is this your pen? 这是你的钢笔吗?(your为形容词性物主代词,后面跟名词)
No,,it isn't, it's hers(her book)。不,是她的。(hers为名词性物主代词,后面不能跟名词/her为形容词性物主代词,后面必须跟名词)
This book is mine.这本书是我的。(mine为名词性物主代词,后面不能跟名词)
