名词性物主代词的用法
表示所有关系的代词叫物主代词，也可叫作代词所有格。可分为两种：名词性物主代词和形容词性物主代词。请看下面表格：
物主代词             单数
                  
                   第一人称    第二人称   第三人称
形容词性物主代词    my            your     his  her  its
名词性物主代词      mine         yours     his  hers  its
含义                我的         你的      他的  她的 它的
                    复数
                   第一人称    第二人称   第三人称
形容词性物主代词    our          your      their
名词性物主代词      ours         yours     theirs
含义                我们的       你们的     他们的
人称代词   形容词性物主代词     名词性物主代词
主格  宾客
 I     me         my               mine
you   you         your              yours
he    him         his               his
she    her         her               hers
we      us         our               ours
they    them       their             theirs
名词性物主代词起名词的作用。为了避免重复使用名词，我们经常用名词性物主代词来代替“形容词性物主代词+名词”的形式。如：
My pen is missing.Mary I borrow yours(=your pen)?
-Is this comb yours?
-No,it's hers.
Is this your book or mine?
A friend of mine came to see me yesterday.
1.用法
1.形容性物主代词用来修饰名词，起形容词的作用，不能单独使用。如：
My parents are both teachers.
我的父母都是老师。
2.名词性物主代词可以单独使用，相当于“形容词性物主代词+名词”，后面不跟名词。如：
May I use your ruler?I have lost mine.
=May I use your ruler?I have lost my ruler.
另外，名词性物主代词还可以用在"n.+of+名词性物主代词“结构中，表示”某人的....“如：
The shoes of hers are very nice.
她的鞋子很漂亮。
Ⅱ.所作成分：
1.形容词性物主代词只能作定语。如：
There is something wrong with his computer.
他的电脑出问题了。
They love their work in the shop.
他们喜欢在商店的工作。
2.名词性物主代词可以作主语、宾语和表语。如：
Your book is interesting,but mine is more interesting.(作主语）
你的书很有趣，但是我的更有趣。
These letters are his. (作表语）
这些是他的信。
I lost my pen this morning.May I borrow yours?  (作宾语 ）
我今天早晨丢了我的钢笔，我能借用一下你的吗？
名词所有格的用法
英语中的名词所有格表示一种所属关系，'s所有格多用于生命的名词。
构成：
①在单数名词的末尾加's 构成名词的所有格，表示”....的"
Tony's mother   托尼的妈妈
Tom's pen    汤姆的钢笔
②在以-s或-es 结尾的复数名词后只需加'.
the girls' bags  女孩们的书包
③在不以-s或-es 结尾的复数名词后，加's构成所有格。
Women's Day  妇女节
④表示时间、距离的名词所有格与有生命的名词所有格构成方法相同。
today's class  今天的课
five minutes' walk   五分钟的路程
注意
①可用名词所有格表示地点。
at any aunt's   在我姑姑家
at the doctor's  在医生的诊所
②如果并列名词各自所拥有某物，每个词后都加's;若表示两人共同拥有的物品，在最后一个名词后加's.
Linda's and Jim's mothers.
琳达和吉姆的妈妈
Lucy and Lily's room
露西和莉莉的房间
