More
structures

Introduce

+
than...”来引出比较的第二部分。

为避免重复，在than后常用that,
those等词来替代前面提到过的名词。
2.我们用“Which...+比较级,...
or...”来表示在两者中选择。
Which

bigger,
the
sun
or
the
moon?
太阳和月亮，哪个更大？
3.我们可以在比较级前加上much,

Now
the
air

our
hometown
is
much
better
than
it
was
before.
现在我们家乡的空气比从前好得多。
4.我们用“比较级+and

His
shoes
are
dirtier
and
dirtier.
他的鞋子越来越脏。
Clothes
are
more
and
more
expensive.
衣服越来越贵。
more
and
more+原级,
只用于以“more”构成比较级的形容词,根据句意也可以用“less”构成降级比较。
5.我们用“
the+比较级...
,
the+比较级...”的结构来表示一方随另一方变化而变化（越……越……）。
The
sooner,
the
better.
越早越好。
The
kinder
we

the
luckier
we
will
be.

the
third
tallest
in
her
class.米莉是她班里第三高的。
The
Yellow
Riveris
the
second
longest
river
in
China.黄河是中国第二长河。
4.我们用“one
of+the+最高级+可数名词复数形式”表示“最……的……之一”。
He
is
one
of
my
best
friends.
他是我最好的朋友之一。
注意：比较级
+
than
any
