一、物主代詞物主代詞是表示某物屬于“誰的”的代詞，分為形容詞性物主代詞和名詞性物主代詞兩種。形容詞性物主代詞相當(dāng)于形容詞，置于名詞之前做定語。如：hername,yourbirthday,theirfriends。名詞性物主代詞相當(dāng)于名詞，不能用于名詞前。見下表：類別形容詞性物主代詞名詞性物主代詞漢語意思單數(shù)形式mymine我的youryours你的hishis他的herhers她的itsits它的復(fù)數(shù)形式ourours我們的youryours你們的theirtheirs他們的形容詞性物主代詞起形容詞作用，在句中只能作定語,也就是說它后面必須跟一個名詞。即：形容詞性物主代詞＋名詞。形容詞性物主代詞前面不能加冠詞a/an/the。Thisismybike.這是我的自行車。Hername’sMary.她的名字是瑪麗。形容詞性物主代詞mine,yours,hers,his等是名詞性物主代詞，相當(dāng)于“形容詞性物主代詞my/your/her/his＋名詞”。名詞性物主代詞的用法：(1)名詞性物主代詞＝形容詞性物主代詞＋名詞(2)名詞性物主代詞在句中作主語、賓語或表語。
