三、名词性物主代词。
mine,
hers,
yours
等是名词性物主代词，相当于一个名词，可以在句子中单独使用。它相当于“形容词物主代词
+
名词”。而形容词性物主代词只能和名词在一起使用。例如：
This
is
your
ruler.
It’s
not
my
ruler.
(=
This
ruler
is
yours.
It’s
not
mine.)
这是你的尺子，它不是我的。
Those
aren’t
his
books.
They’re
her
books.
(=
Those
books
aren’t
his.
They’re
hers.
)
那些书不是他的。它们是她的。
名词性物主代词
mine
(mine=my
+名词)
yours
(yours=your+名词）
his
(his=his+名词)
hers
(hers=her+名词)
名词性物主代词=形容词性物主代词+名词
(为了避免重复)
(后面就不再加东西了)
Is
this
your
pen?
No,
it
isn't.
It's
her
pen.
(为了避免重复)
No,
it
isn’t.
It’s
hers.
(hers=her
pen)
Is
this
her
pencil?
No,
it
isn’t.
It’s
my
pencil.
(为了避免重复)
No,
it
isn’t.
It’s
mine.
(mine=my
pencil)
注意：在使用名词性物主代词时，必须有特定的语言环境，也就是要省略的名词大家已经知道，已经提起过。
例：It‘s
hers.
是她的。
（单独使用大家不知是怎么回事，不可以这样用）
There
is
a
book.
It's
hers.
那有本书。是她的。
（先提及，大家才明白）
