一、名詞性物主代詞
物主代詞是表示所有關(guān)系的代詞，分為形容詞性物主代詞和名詞性物主代詞。名詞性物主代詞的形式如下：
Grammar Focus
單數(shù) 復數(shù) 第一 人稱 第二 人稱 第三人稱 第一 人稱 第二 人稱 第三
人稱
mine 我的 yours 你的 his 他的 hers 她的 its 它的 ours 我們的 yours 你們的 theirs
他/她/ 它們的
1.名詞性物主代詞在句子中獨立使用，相當于“形容詞性物主代詞+名詞”，其后不能接名詞。
There is something wrong with my computer. Could I use yours
我的電腦出問題了。我可以用你的嗎？
Grammar Focus
2.名詞性物主代詞在句中可作主語、賓語、表語等。作主語時，謂語動詞的單復數(shù)形式由名詞性物主代詞所指代的名詞的數(shù)來決定。
My tennis shoes are right here. His are over there.
我的網(wǎng)球鞋就在這里，他的在那邊。
