比较级用于比较两个主体。组成句子的方式是将形容词或副词变成比较级的形式，之后要用than引出比较的对象。
形容词比较级的构成
——?规则变化：
单音节和部分双音节词
一般在词尾加-er
tall→taller
long→longer
以不发音字母e结尾的词，在词尾加-r
fine→finer
late→later
重读闭音节词且词尾只有一个辅音字母，双写辅音字母再加-er
big→bigger
thin→thinner
?以“辅音字母?+?y”结尾的双音节词，先把“y”改为“i”再加-er
easy→easier??
friendly→
friendlier
比较级的句子结构：
原来的句子结构不变，只是将形容词变成比较级的形式，然后在后面用than引出所比较的对象。例如：
1.
Shanghai
is
busy.
Shanghai
is
busier
than
Hangzhou.
2.
Shanghai
is
an
old
city.
Shanghai
is
an
older
city
than
Shenzhen.
比较级常用句型：
1.
A+动词+形容词比较级+than
+B
意为“A比B更……”
This
tree
is
taller
than
that
one.
The
climate
in
Beijing
is
hotter
than
that
of
Ningbo.
A
B
A
B
2.
表示两者之间的选择,
可使用
Which
is
+
比较级,
…or…?
Which
is
longer,
this
one
or
that
one?
3.
……比较级+and+比较级……“越来越…”
In
spring,
the
days
are
getting
longer
and
longer.?
4.
as+形容词原形+as…
“和……一样……”
Tom
is
as
tall
as
Mike.?
This
girl
is
as
beautiful
as
that
one.
I
was
as
happy
as
John
yesterday.
否定形式：not
as…as…或
not
so…
as…
意为“和……
不一样”、
“不及／不如……”。
Tom
is
not
as
tall
as
Mike.
Tom
is
not
so
tall
as
Mike.
This
book
isn’t
as
interesting
as
that
one.
注意：
修饰比较级的副词要用much,
a
lot,
a
little,
a
bit,
far,
even,
still等。very不能和比较级连用。如：
It
was
cold
yesterday,
but
it’s
even
colder
today.
昨天天气很冷，但今天更冷。
He
is
getting
much
fatter
these
days.
他这两天变得更胖了。
