——形容词副词的比较级与最高级
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！
This ruler is as long as that one. 这把尺子和那把一样长。(变否定句)
This ruler is not as/so long as that one.
二、形容词比较级最高级变化规则
①单音节词比较级在词尾加er,最高级加est
cold —colder —coldest tall —taller —tallest
high —higher —highest long —longer —longest
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 —hotter —hottest
wet — wetter —wettest thin —thinner —thinnest red—redder —reddest fat —fatter —fattest
sad —sadder —saddest
④以辅音字母+y结尾的词把y变i再加er或est
easy — easier — easiest early — earlier — earliest
funny — funnier — funniest happy — happier — happiest
heavy— heavier — heaviest dirty — dirtier — dirtiest
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 difficult excitied tired
careful popular expensive boring fun
⑥不规则变化
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)
far —— farther —— farthest (距离远)
far —— further —— furthest (除距离外,还指程度上更进一步的)
★★口诀：合二为一共三对, “坏、病”、“两多”并“两好”； 一分为二有两个，一是“远来”、二是“老”； 还有一词含双义，只记“少”来不记“小”。

◆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
4.形容词比较级句式:
①A + be + 形容词的比较级 + than + B. (A比B…)
②Which/Who +be +形容词比较级, A or B? (哪个/谁更…, A 还是B？)
练习写出下列句子
凯特很瘦。
凯特和玛丽谁更瘦？
玛丽比凯特更瘦。
玛丽比凯特更瘦吗？是的,她是。
这个书包和这个箱子不一样沉。
这个书包和这个箱子哪个更沉？
这个箱子比书包更沉。
5.副词比较级句式:①A＋实义动词＋副词的比较级＋than B. (A…得比B…)
②Which/Who +实义动词三单, A or B? (哪个/谁…得更…, A还是B？)
练习写出下列句子
自行车和轿车哪个走得快？
轿车比自行车走得快
这只羊和这只狗跑得不一样快。
这只羊比狗跑得快吗？
吉姆比汤姆上床睡觉早。
(上句同义句) ___________________________________________
6.比较级特殊用法:
①the +比较级+of the two… —— “两者中较…的”
他是两个男孩中较高的。He’s the taller of the two boys.
②“比较级+and+比较级”或“more and more +多音节词” —— “越来越…”
他越来越高。 He’s taller and taller.
英语越来越重要 English is more and more important.
③The+比较级…, the+比较级… —— “越…, 越…”
你越快乐就越美丽。The happier you are, the more beautiful you are.
④not +比较级+than… —— “不如…, 不比…”
no +比较级+than… —— “一样都不…”
You are not taller than me. 你不比我高。
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 sister’s class.
她比她妹妹班里任何一个女孩都漂亮。
(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.
②the + 最高级 +(n.) + of +同类事物
这本书是所有书中最有趣的。The book 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 I. ( )
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. ( )
My bag is bigger than yours. ( )
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 than that of Shanghai. ( )
Notes:当主语有后置定语修饰时,为保证比较对象一致,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.
