Question

one做代词时表示什么?

Answer 1

亲爱的楼主：
一、替代词
one
的用法
1.
用作替代词时,表示泛指,既可指人,也可指物,常用来代替上文出
现过的单数名词
,
以免重复.所指的人或物属于同类事物中不同的一个,即替代
的是一个带不定冠词的可数名词的单数形式.如：
I have a dictionary.Do you have one?
(one = a dictionary)
I have lost my old watch
,
this is a new one.
(one my old watch)
2.
当
one
被定语修饰,而仍是泛指时,前面应加不定冠词
a
/
an
.如：
I have two story books,a thick one and a thin one.
Your question is a very difficult one.
3.
当
one
被定语修饰,表示特指时,前面应加定冠词
the
.如：
—
Which
sweater would
you
like
better,
the
red
one
or
the
yellow
one?
—
The red one.
4.
当
one
带有定冠词
the
时表特指.如：
The girl I saw was older than the one you were dancing with.
( the one = the girl)
注意：这里不能用
that
,因为
that
不可替代表示人的名词,而
one
却
可以.
The dictionary of yours is different from that of mine.
(that = the dictionary = the one)
5.one
的复数形式是
ones
,有时
ones
前往往带有定语,否则就用
some
.如：
He doesn
’
t like red skirts.He likes white ones.
I don
’
t like this hat
,
show me the other ones (some others).
6.one
替代的是带不定冠词的名词,并不是指它前面出现的名词一定
带有不定冠词
,
而是指它本身所在的位置上所替代的那个名词一定是带不定冠词
的名词.如：
The clean bowls are in the cupboard
—
if you need one.(one
替代的是
a clean bowl)
All
the
other
boys
have
history
books
and
they
will
catch
up
with
me if I don
’
t get one.
( one
替代的是
a history book )
7.
在某些情况下可不用替代词
one
.如：
I wont go in your car.Ill use my own.
Of all the runners my brother was the fastest.
I have only one bike but you have two.
