◆“不要负累的”名词性物主代词
名词性物主代词是物主代词的一种，用于代替前面提到过的人或事物，相当于名词，不能用于名词前，可以直接作主语、宾语或表语等，有人称和数的不同。形容词性物主代词与名词性物主代词对应表：
形容词性
my
your
his
her
our
their
名词性
mine
yours
his
hers
ours
theirs
形容词性物主代词→
后接名词；
名词性物主代词→
后不接名词。
e.g.
This
is
my
pencil
and
that
is
hers.
这是我的铅笔，那是她的。
考点1
名词性物主代词
名词性物主代词后不能再接名词！
形容词性物主代词
名词性物主代词=
形容词性物主代词+
名词，相当于名词，常作主语、表语、宾语等。用作主语时，谓语动词的数应与所指对象保持一致。
考点2
e.g.
—Are
these
keys
mine
这些钥匙是我的吗？
—No.
Yours
are
in
the
bag.
(作主语)
不是。你的钥匙在包里。
This
is
my
book
and
that
is
yours.
(作表语)
这是我的书，那是你的书。
yours=your
book
Yours=Your
keys,
是复数，所以be
动词用are。

it
for
me.
[天津]

C.

速记小法
物主代词用法口诀：
物主代词分两家，形容词性名词性。
形容词性能力差，自己不能来当家。
句子当中作定语，身后定把名词加。
物主代词名词性，相当名词可单用。
his，its
无变化，my
和mine
要牢记。
其余变形规律化，变形后加s尾巴。
