物主代詞 第一人稱 第二人稱 第三人稱
形容詞性物主代詞 單數 my your his, her, its
復數 our your their
名詞性 物主代詞 單數 mine yours his; hers; its
復數 ours yours theirs
物主代詞
物主代詞的用法
形容詞性物主代詞
它在句中作定語， 修飾名詞。
它在句中可作主語、賓語、表語等。作主語時，謂語動詞的單復數形式由名詞性物主代詞所指代的名詞的數來決定。
名詞性物主代詞
它相當于“形容詞性物主代詞+名詞”，其后不能再加名詞。
名詞性物主代詞
形容詞性物主代詞與名詞性物主代詞
These are her keys.
= These keys are hers.
用法區別如下：
形容詞性物主代詞相當于形容詞，放在名詞前面，相當于…的；名詞性物主代詞起名詞的作用，后面不需要再加名詞。
形容詞性物主代詞+名詞=名詞性物主代詞
形容詞性物主代詞
名詞性物主代詞
a. 名詞性物主代詞起名詞的作用。
Look at the two pencils. The red one is your pencil，the blue one is mine.
b. 在使用名詞性物主代詞時，必須有特定的語言環境，也就是要省略的名詞大家已經提起過。
e.g. It's hers. 　是她的。
（單獨使用大家不知是怎么回事，不可以這樣用。）
There is a book. It's hers. 　這有本書。是她的（書）。
（這里的hers=her book）
有“名”則"形“，無“名”則“名”
c. 名詞性物主代詞=形容詞性物主代詞+名詞
為避免重復使用名詞，有時可用“名詞性物主代詞”來代替“形容詞性物主代詞+名詞”的形式。
My bag is yellow, her bag is red, his bag is blue and your bag is pink.
d. 名詞性物主代詞可以用在介詞of的后面，相當于“of+名詞所有格”——名詞的雙重屬格。
Some friends of hers will come here tomorrow.
她的幾個朋友明天將到這兒來。
Two classmates of my sister's came to see her yesterday.
我妹妹的兩位同學昨天來看過她。
照例子改寫同義句：
This is my pencil. This pencil is mine.
1.This is her schoolbag. _________________.
2. Is that your watch _________________ 3. These are his keys. ________________.
4. Are those her books _________________ 5. They are my erasers. ________________.
This schoolbag is hers
Is that watch yours
These keys are his
Are those books hers
The erasers are mine
1. This is her eraser. (改一般疑問句)
2. Is that Mary’s pen (否定回答)
3. These are my books. (改為一般疑問句）
4. Is his pen here (肯定回答)
Is this her eraser
No, it isn’t.
Yes, it is.
Practice:
Are these your books
