i'm three years -______(young) than my brother,讲讲为什么?

Question

为什么比较级前可以加数字?

Answer 1

younger
原因如下:参考比较级的语法
比较级前的修饰语
在使用比较级的时候，为使比较的程度更加确切，可以在比较级前加上一些修饰语，这些修饰语有:
1.数词短语，用来表示具体的数量
My
sister
is
two
years
older
than
I.
2.a
little,
a
bit表示“一点儿”，稍微之意
She
is
a
little
shorter
than
Han
Mei.
This
book
is
a
bit
thicker
than
that
one.
3.some(肯定句)，any(否定句、疑问句)，表“…一些”
I’m
feeling
some
better.
The
man
was
too
tired
to
go
any
farther.
4.
much,
a
lot,
by
far表示“…得多”
Out
school
is
much
more
beautiful
than
it
was
before.
5.Still,
even表“…更…”，“…还是…”
My
watch
is
expensive,
but
this
is
even
more
expensive
注:very,
quite,more等词一般用来修饰形容词、副词的原级，不能用来修饰比较级。
