Question

one ,ones ,the one ,the ones用法区别

Answer 1

one
1)代替上文中出现过的单数可数名词，表泛指(同类但不是同一)前面可以有冠词或形容词，也可以有this或that或another，但前不能有物主代词:
e.g.:
I
have
lost
my
pen.I’m
going
to
buy
one.
This
pen
doesn’t
work.
I
must
buy
another
one.
I
prefer
this
one
to
that
one.
比较:
I’m
looking
for
a
flat.
I’d
like
a
small
one
with
a
garden.
I’m
looking
for
a
flat.
I’d
like
one
with
a
garden.
(不能说:...
a
one
with
a
garden.)
2)
作为不定人称代词,
可泛指“任何一个人”，有one's
和oneself形式。多用于正式文体，口语中也可用he/his代替第二个one/one's.
e.g.:
One
has
to
take
care
of
oneself
and
one's
family
if
he
can.
One
shouldn't
hesitate
to
correct
his/one's
mistakes.
If
one
wants
to
see
the
ruins,
he
must
find
his
own
guide.
(如果一个人想看那废墟,
他必须找自己的向导。)
ones
ones是one的复数形式，常用来代替复数可数名词，表泛指，前面不用物主代词修饰，也不用these或those来直接修饰，除非ones前面有形容词:
e.g.:
I
have
a
new
coat
and
several
old
ones.
These
yellow
waistcoats
are
so
small.
I
want
those
green
ones.
the
one
替代表特指的单数名词:
Here
are
six
rings.
Pick
out
the
one
you
like
best.
Hand
me
my
coat.
It's
the
one
hanging
on
the
wall.
Your
dictionary
is
more
useful
than
the
one
my
uncle
gave
me.
the
ones
替代表特指的复数名词:
Don’t
buy
the
expensive
apples;
get
the
cheaper
ones.
I’d
like
to
try
on
those
shoes，the
ones
at
the
front
of
the
window.
Are
they
the
ones
who
moved
here
recently?
总之:
1.one/ones用来代替前面提到过的可数名词，one指代单数,
ones指代复数，所代替的是同名异物，表示泛指，可有前置定语或后置定语，也可单独使用，特指时必须加
the，用the
one/ones
。
