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(gè)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。

名詞性物主代詞1.Hispenisgreen.Mineisblue.(作主語)

他的鋼筆是綠色的，我的(鋼筆)是藍(lán)色的。2.Myeraserisinthepencilbox.Whatabout

yours？(作賓語)我的橡皮在鉛筆盒里，你的呢？（=Hispenisgreen,mypenisblue.)(=Myeraserisinthepencilbox,whataboutyoureraser?)3.Thisismyruler,thatoneishers.(作表語)這是我的直尺，那把是她的。(=Thisismyruler,thatoneisherruler.)[口訣]物主代詞分形、名，形式、用法各不同；形容詞性先出場(chǎng)，我的my你的your；男的his女的her，它的its不加撇；我們的our他們的their，別忘記！物主代詞形變名，多數(shù)詞尾加“s”；my變mine須分明，his和its是本身；形跟名詞，名不跟，用法牢記不會(huì)錯(cuò)！

口訣

有“名”則“形“，無“名”則“名”

意思是：后面是名詞的話，前面就要用形容詞性物主代詞。后面沒有名詞的話，就用名詞性物主代詞。物主代詞的注意事項(xiàng)練一練，填一填Thisismybook.
