什么情况下用名词性物主代词好

admin

形容词性物主代词和名词性物主代词用法上的区别

(1)形容词性物主代词相当于形容词,在句中只可作定语,修饰名词。如:their

teacher

is

miss

gao.

(2)名词性物主代词相当于一个名词短语,在句中可作主语、宾语等成分。如:

this

is

your

bike,

mine

is

under

the

tree.

(作主语)

这是你的自行车,我的在树下。

i

like

my

pen,

i

don’t

like

hers(作宾语)

我喜欢我的钢笔,我不喜欢她的。

that

bag

isn’t

mine,

it's

yours.

(作表语)

那个书包不是我的,是你的。

(3)名词性物主代词作主语时,谓语动词的单、复数形式取决于它所替代的名词的数。如:

my

trousers

are

long,

hers

are

short.

我的裤子长,她的裤子短。

your

school

is

big,

ours

is

small.

你们的学校大,我们的学校小。

(4)形容词性物主代词不可单独使用,其后必须有被修饰的名词。如:

那是他的椅子,我的在那儿。

that's

his

chair,

my

is

over

there.

正that's

his

chair,

mine

is

over

there.

正that's

his

chair,

my

chair

is

over

there.

whose用法

whose不等于who's。whose是who的所有格形式,意为“谁的”,而who's是who

is的缩略形式,意为“谁是”。但whose与who's同音,都读作[hu:z]。

whose在句中可作表语、定语等。如:

whose

is

that

computer?

那台电脑是谁的?(作表语)

whose

sweaters

are

these?

这些是谁的毛衣?(作定语)

whose用来对物主代词及名词所有格进行提问:

1.提问形容词性的物主代词。如:

these

are

my

bananas.

→whose

bananas

are

these?

2.提问名词性的物主代词。如:

that

bedroom

is

mine.

→whose

is

that

bedroom?

hers

are

in

the

classroom.

whose

are

in

the

classroom?

3.提问名词所有格(不包括of构成的所有格)。如:

those

are

the

twins’

bags.

whose

bags

are

those?

tom's

mother

is

a

good

teacher.

whose

mother

a

teacher
