比较级与最高级语法专
这把尺子和那把一样长。(变否定句)
讲
This ruler is not as/so long as
形容词分为三种等级:原级,比较级与最
高级。
一、形容词的原级及用法
◆形容词的原级(形容词本来面目不作变
化)
1.表示没有进行比较或进行同级比较
2.可以修饰原级的词: very quite enough(“足够”,用在形容词后)
so pretty too how rather(相当) (not) as…as (“(不)
像…一样”,同级比较) not so…as (“不像…一样”,同级比较)
e.g. How happy we are! 我们多么高兴啊！
that one.
二、形容词比较级最高级
变化规则

加est
cold —colder —coldest tall

②以字母e结尾的词只加r或st
nice —nicer —nicest late —later —latest fine —finer —finest
③重读闭音节双写辅音字母再加er或est
big —bigger —biggest hot

⑤多音节词、部分双音节词(特别是ful结尾及v.+ed/ing构成的形容词)及个别单音节词(fun)在前面加more或most
interesting important

little — less — least good / well — better — best
bad / ill / badly —— worse —— worst
many / much —— more —— most
old —— older —— oldest (年龄
大的,与than连用)
old — elder — eldest(“年长的”,只作定语不与than连用) 4.形容词比较级句式:
far —— farther —— farthest ①A + be + 形容词的比较级 + than + B. (距离远)
far —— further —— furthest (除距离外,还指程度上更进一步的) ◆副词比较级和最高级的变化规则大致与此相同
三、比较级用法
1.表示两者之间进行比较,“更…”
2.可以修饰比较级的词: much = a lot
(…得多)
a little = a bit (…一点点) even (甚至) far (远远…) any (丝毫,稍微, 用于否定和疑问句中) 3.比较级标志: than or
(A比B…)
②Which/Who +be +形容词比较级, A or B? (哪个/谁更…, A 还是B？)

6.比较级特殊用法:
①the +比较级+of the two… —— “两者中较…的”
more +多音节词” —— “越来越…”
他越来越高。 He’s taller and
taller.

more important.

她比她妹妹班里任何一个女孩都漂亮。 You are no taller than me. 你和我
一样都不高。
⑤比较级+than any other +sig.+in+同
一范围
—— “比同一范围中其他任何一个更…”
比较级+than any +sig.+in+非同一范围——“比非同一范围中任何一个更…”
She’s nicer than any other girl in her class.她比班里其他任何一个女孩
都漂亮。
(主语本身就在比较范围之中,因此是在
同一范围就主语与其他任何一个比较)
She’s nicer than any girl in her
(主语不在该较范围之中,因此主语可
以与该范围内任何一个作比较)
◆该用法虽然出现了in所引导的比较范
围但是仍要用比较级,此成为用比较级
表示最高级,实质是最高级。
四、最高级
用法 1.表示三者或三者以上的比较,“最…” 2.形容词最高级前必须加the,副词前的
the可以省略。
3.最高级标志:in of or
4.句式:①the + 最高级 +(n.) + in +
比较范围
我是我们班最聪明的。I’m the
cleverest in our class.
She looks nicer than I. ②the + 最高级 +(n.) + of +同类事物

is the most interesting of all the books.
③Which/Who +v.(单数) +最高级, A, B
or C?
Jay, Will和JJ谁最收欢迎？ Who is
the most popular, Jay, Will or JJ? 五、例题解析与
难点攻克
◆主语为人时than后面的比较对象若用
代词用主格还是宾格？ 请判断正误:
1. She looks nicer than I do. ( )
( )
She looks nicer than me.
( )
Notes:than可以作连词其后跟省略句,该省略句构成为(主格+助动词/be/情态
动词),而谓语部分可省略; than还可以
作介词在口语中跟人称代词宾格
◆主语为物时的比较对象的一致性问题
2.Her hair is longer than her mother.
( )
Her hair is longer than her
mother’s. ( )
3.My bag is bigger than you.
( )
My bag is bigger than your.
( )
My bag is bigger than your bag. than that of Shanghai. ( )
( )
My bag is bigger than yours. Notes:当主语有后置定语修饰时,为保证( )
Notes:比较对象应与主语对等,当主语为限定词+n.时,than后的其比较对象可为:
①限定词+n.
②名词所有格(一般省略其后相同的名词)
③名词性物主代词(=形容词性物主代词+n.) mine yours his hers its ours theirs
4.The weather of Beijing is colder than Shanghai.
( )
The weather of Beijing is colder
比较对象一致,常用that/thoes 指代比较对象。
◆比较范围
5.The Changjing River is the longest
____ China.
The Changjing River is the longest ____all the rivers in China.
Notes:在最高级中,in后跟比较范围,of后跟进行比较的同类事物。 6.China is larger than any country in
Asia. ( ) China is larger than any other
country in Asia( )
◆同义句转换问题 7.He is taller than anyone else in the class.
= He is taller ____ ____ _____ student in the class.
= He is taller _____ _____ ______ students in the class.
= He is the ____ ____ student in the class.
Notes:同一范围内比较
比较级+than any other +sig.+in =比较级+than anyone else +in…
=比较级+than the other +pl.+in… (只有同一范围比较才能出现other/else)
非同一范围内比较 比较级+than any+sig.+in…
8. This coat is more expensiver than
that one.
= That coat is ________ than this
one.
= That coat isn’t _____ big _____
this one.
Notes: A+v.+比较级+than+B (A
比B更…)
= B+v.+比较级反义词+than+A
(B 比A更…)
= B+v.+not as(so)… as… (B与A不一样…)
◆“less+多音节词原级+than…” “不如…” — 降级比较
= That coat is less expensive
than this one.
