一、物主代词物主代词是表示某物属于“谁的”的代词，分为形容词性物主代词和名词性物主代词两种。形容词性物主代词相当于形容词，置于名词之前做定语。如：hername,yourbirthday,theirfriends。名词性物主代词相当于名词，不能用于名词前。见下表：类别形容词性物主代词名词性物主代词汉语意思单数形式mymine我的youryours你的hishis他的herhers她的itsits它的复数形式ourours我们的youryours你们的theirtheirs他们的形容词性物主代词起形容词作用，在句中只能作定语,也就是说它后面必须跟一个名词。即：形容词性物主代词＋名词。形容词性物主代词前面不能加冠词a/an/the。Thisismybike.这是我的自行车。Hername’sMary.她的名字是玛丽。形容词性物主代词mine,yours,hers,his等是名词性物主代词，相当于“形容词性物主代词my/your/her/his＋名词”。名词性物主代词的用法：(1)名词性物主代词＝形容词性物主代词＋名词(2)名词性物主代词在句中作主语、宾语或表语。
