大多数形容词（性质形容词）和副词有比较级和最高级的变化，即原级、比较级和最高级，用来表示事物的等级差别。原级即形容词的原形，比较级和最高级有规则变化和不规则变化两种。
1) 规则变化
单音节词和少数双音节词，加词尾-er，-est来构成比较级和最高级。
构成法原级比较级最高级
一般单音节词tall(高的) taller tallest
未尾加-er,-est great(巨大的) greater greatest
以不发音的e结尾nice(好的) nicer nicest
的单音词和少数large(大的) larger largest
以- le结尾的双able（有能力的) abler ablest
音节词只加-r,-st
以一个辅音字母big(大的) bigger biggest
结尾的闭音节单hot热的) hotter hottest
音节词，双写结
尾的辅音字母，
再加-er，-est
"以辅音字母+y" easy(容易的) easier easiest
结尾的双音节词，busy(忙的) busier busiest
改y为i，再加
-er，-est
少数以-er，-ow clever(聪明的) cleverer cleverest
结尾的双音节词narrow(窄的) narrower narrowest
未尾加-er，-est
其他双音节词和important(重要的)
多音节词，在前more important
面加more，most most important
来构成比较级和easily(容易地)
最高级。more easily
most easily
2) 不规则变化
原级比较级最高级
good(好的)/ better best
well(健康的)
bad (坏的)/ worse worst
ill(有病的)
old (老的) older/elder oldest/eldest
much/many(多的) more most
little(少的) less least
far (远的) farther/further farthest/furthest
as + 形容词或副词原级+ as
1）在否定句或疑问句中可用so… as。
He cannot run so/as fast as you.
2）当as… as 中间有名词时采用以下格式。
as +形容词+ a +单数名词
as + many/much +名词
This is as good an example as the other is.
I can carry as much paper as you can..
3）用表示倍数的词或其他程度副词做修饰语时，放在as的前面。This room is twice as big as that one.
Your room is the same size as mine.
4) 倍数+ as + adj. + as <=> 倍数+ then + of
This bridge is three times as long as that one.
This bridge is three times the length of that one.
Your room is twice as large as mine.
Your room is twice the size of mine.
比较级形容词或副词+ than
You are taller than I.
They lights in your room are as bright as those in mine.
注意：
1）要避免重复使用比较级。
(错) He is more cleverer than his brother.
(对) He is more clever than his brother.
(对) He is clever than his brother.
2）要避免将主语含在比较对象中。
(错) China is larger that any country in Asia.
(对) China is larger than any other countries in Asia.
3）要注意对应句型，遵循前后一致的原则。
The population of Shanghai is larger than that of Beijing.
It is easier to make a plan than to carry it out.
4）要注意冠词的使用，后有名词的时候，前面才有可能有名词。
比较：Which is large, Canada or Australia?
Which is the larger country, Canada or Australia?
She is taller than her two sisters.
She is the taller of the two sisters.
可修饰比较级的词
1）a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even等
2）还可以用表示倍数的词或度量名词作修饰语。
3）以上词(除by far)外，必须置于比较级形容词或副词的前面。
典型例题:
1）---- Are you feeling ____?
---- Yes，I'm fine now.
A. any well
B. any better
C. quite good
D. quite better
答案：B. any 可修饰比较级，quite修饰原级，well的比较级为better.
2）The experiment was____ easier than we had expected.
A. more
B. much more
C. much
D. more much
答案：C. much可修饰比较级，因此B，C都说得通，但easier本身已是比较级，不需more，因此C为正确答案。
3）If there were no examinations, we should have ___ at school.
A. the happiest time
B. a more happier time
C. much happiest time
D. a much happier time
答案：D。
many,old 和far
1) 如果后接名词时，much more +不可数名词
many more +可数名词复数
2) old 有两种比较级和最高级形式: older/oldest 和elder/eldest。elder，eldest 只用于兄弟姐妹的长幼关系。
My elder brother is an engineer.
Mary is the eldest of the three sisters.
3) far 有两种比较级，farther，further. 在英语中两者都可指距离。
在美语中，father 表示距离，further表示进一步。
I have nothing further to say.
the + 最高级+ 比较范围
1) The Sahara is the biggest desert in the world.
形容词最高级前通常必须用定冠词the，副词最高级前可不用。
形容词most前面没有the，不表示最高级的含义，只表示"非常"。It is a most important problem.
=It is a very important problem.
注意：使用最高级要注意将主语包括在比较范围内。
(错) Tom is the tallest of his three brothers.
(对) Tom is the tallest of the three brothers.
2) 下列词可修饰最高级，by far, far, much, mostly, almost
This hat is nearly / almost the biggest.
注意：
a. very可修饰最高级，但位置与much不同。
This is the very best.
This is much the best.
b. 序数词通常只修饰最高级。
Africa is the second largest continent.
3) 句型转换：
Mike is the most intelligent in his class.
Mike is more intelligent than any other students in his class.
4) "否定词语+比较级"，"否定词语+ so… as"结构表示最高级含义。Nothing is so easy as this.
=Nothing is easier than this.
=This is the easiest thing.
和more有关的词组
1) the more… the more… 越……就越……
The harder you work，the greater progress you'll make.
2) more B than A 与其说A不如说B
less A than B
He is more lazy than slow at his work.
= He is less slow than lazy at his work.
3) no more… than… 与……一样……，不比……多
The officials could see no more than the Emperor.
no less… than… 与……一样……
He is no less diligent than you.
4) more than 不只是，非常
She is more than kind to us all.
典型例题
1）The weather in China is different from____.
A. in America
B. one in America
C. America
D. that in America
答案：D. 本题意为"中国的天气比美国热。"比较的是天气而不是国家，C不能选。A没有名词，后句成分不全，排除。B和D中，B中的one常用来代替可数名词，而that可车以代替不可数或抽象名词，所以选D。
2）After the new technique was introduced，the factory produced ___ tractors in 1988 as the year before.
A. as twice many
B. as many twice
C. twice as many
D. twice many as
答案C. 此句意为"这个厂1988能生产的拖拉机是往年的两倍"。表示倍数用"倍数+ as + 形容词原形+ as +比较对象"的句型。所以此句答案为C。
This ruler is three times as long as that one.

比较级与最高级语法专讲 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/so…as (不)像/如…一样, 同级比较= less + adj ./adv .原形+than e.g. 我们多么高兴啊！How happy we are ! 这把尺子和那把一样长。 This ruler is as long as that one . (变否定句) 这把尺子不如那把长 This ruler isn’t as/so long as that one . This ruler is less long than 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 excited 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) ◆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 +谓语动词+ 形容词的比较级+ than + B. (A比B…) 玛丽比凯特更瘦。Mary is thinner than Kate. ②Which/Who +谓语动词+形容词比较级, A or B? (哪个/谁更…, A 还是B？) Who runs faster , Mary or Kate ? 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 one 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 . ④the +序数词+形容词最高级+n 意为第几最……的 The Yellow river is the second longest river in China. 黄河是中国第二长的河流。 ⑤比较级+than any other +n单.+in+同一范围 她比班里其他任何一个女孩都漂亮。She’s more beautiful than any other girl in our class. = 她是班上最漂亮的女孩。She’s the most beautiful girl in our class. ◆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.比较级前必须加the , 副词前的the可以省略。 3.最高级标志:in of or(三者及三者以上) in后跟比较范围, of后跟进行比较的同类事物。 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 smartest 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。This book is the most interesting of all the books. ③Which/Who +v.(单数) +最高级, A, B or C? Jay, Will和Jack谁最收欢迎？Who is the most popular, Jay, Will or Jack? 五、例题解析与难点攻克 ◆主语为物时的比较对象的一致性问题 1. My bag is bigger than you. 误 My bag is bigger than your. 误 My bag is bigger than your bag. 正 My bag is bigger than yours. 正 比较对象应与主语对等,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 in Beijing is colder than that in Shanghai. 当主语有后置定语修饰时,为保证比较对象一致,常用that/those指代比较对象。

小学六年级英语比较级和最高级的知识讲解 学习重难点： 1.熟练掌握形容词和副词比较级和最高级的构成。 学习过程及内容： 比较级：两者间的比较。最高级：三者及其以上比较，选出一个“最”。 一.了解什么是单音节，双音节和多音节。 二.掌握单音节词和部分双音节词比较级和最高级的构成、用法。 1.构成。 知识点（1）.一般情况在原级词尾加-er构成比较级，加-est构成最高级。 如：Small→smaller→smallest clever→cleverer→cleverest。 例题：Short tall Cheap narrow 知识点（2）.以e结尾的词，直接加-r 或-st。 如：large→larger→largest nice→nicer→nicest 注意：late→later（较晚的）→latest（最新近的）(时间的先后） late→latter（稍后的）→last（最后的）(顺序上的先后）例题：nice able safe 知识点（3）.以一个辅音字母结尾,其前面的元音字母发短元音的形容词的比较级和最高级,是双写该辅音字母然后再加-er和-est。（注意：这里是字母，不是音标。辅音字母是除a,e,i,o,u五个元音字母以外的都是辅音字母。） 如：big→bigger→biggest。 例题：hot fat thin 知识点（4）.以“辅音字母+ y”结尾的词，先变“y”为“i”，再加-er 或-est。 如：happy→happier→happiest easy→easier→easi est 例题：heavy
busy lucky 知识点(5)不规则变化,常见的有这六个。 good / well→better→best bad / ill→worse→worst many / much→more→most little→less→least far→farther→farthest(表示距离) / far→further→furthest (表示程度) old→older / elder→oldest (表示新旧或年龄) / eldest (表示兄弟姐妹之间的长 幼关系） 2.用法。 比较级：A +be(is/am/are) + 形容/副词比较级+ than + B 如：Yao Ming is tall than me. I’m short than Yao Ming. 例题：(1)The red box is (heavy)than the blue box. (2)I’m three yeas (older/elder)than him. (3)This man is than that man. 最高级：A+the+形容/副词最高级+表示的范围（in比较对象不是同一类，of比较对象时同类） 如：Tom is the tallest student in his class. The Yellow River is the scend longest river in Chian. 例子：(1)Apple A is the （big) of the three/ in the box. (2)用heavy,bad的比较级和最高级造句。 (3)Which subject do you like ,maths or english? A.good B.better C.well D.best 三.大部分双音节词和多音节词的构成。 大部分的双音节词和多音节词，比较级在前面加more，最高级在前面加most。 注意：（1）形容词最高级前通常必须用定冠词the，副词最高级前可不用。 （2）形容词most前面没有the，就没有最高级的意思，不表示最高级的含义，只表示"非常"，用来加强语气之意。 如：beautiful→more beautiful→most beautiful different→more different→most different easily →more easily →most easily
形容词比较级和最高级的用法 形容词原级的用法 1.说明人或事物自身的特征、性质或状态时，用形容词原级。 Eg.The flowers in the garden are beautiful. 2.有表示绝对概念的副词very,so,too,enough,quite等修饰时，用形容词原级。 3.表示A与B在某方面程度相同或不同时用形容词原级。 肯定句中的结构：A +as+形容词原级+as+B 否定句中的结构：A+as/so+形容词原级+as+B 表示“A是B的……倍”时，用“A+倍数+as+形容词原级+as+B”结构（一倍once，两倍twice，三倍及以上：数字+times） half as +形容词原级+as表示“……是……的一半” 形容词比较级的用： 1．比较级：常用于“比较级+than”结构。如：Cats aremore lovely than other animals 2．形容词的比较级可用much，a little，a lot，even。a bit，still，far，rather，any等修饰，使原来的比较级在语意上更加明确。如：Chickens are much smaller than cows. 3．表示两者之间进行选择“哪一个更……”时，用句型“which/who is +形容词比较级，A or B？”表示。 4．表示“几倍于……”时，用“倍数+比较级+than”表示。如:I’m three years younger than you 比较结构中还须注意以下问题： 1．比较级与最高级的结构还可以转换，意思不变。如：The Changjiang River is longer than any other river in China=The Changjiang River is the longest river in China. 2．当某一事物与其他事物做比较时，被比较事物中不能包括本身。如：He is taller than any other student in his class. 3．如果比较对象相同，可用that/those代替第二个比较对象。如：The weather in Shanghai is better than that in Wuhan. 4．两个比较级用and 连在一起可表达全面增加或减少，意为“越来越……”。

形容词、副词的比较级和最高级用法 大多数形容词和副词有三个等级：原级、比较级和最高级。 1、原级即原型。 2、比较级，表示“较……”或“更……一些”。 3、最高级表“最……”。 一、形容词、副词比较级和最高级的构成。 比较级和最高级有规则变化和不规则变化两种。（一）规则变化 ★★1.单音节以及少数双音节的词后面直接加-er , -est tall taller tallest ★★2.以不发音的e结尾只加-r，-st nice nicer nicest ★★3.以一个元音加一个辅音字母结尾的单音的辅音字母，再加-er，-est thin thinner thinnest 特别提醒： (1)以形容词+ly构成的副词要在前面加 more，most new, few, slow, clean等词含有字母组合,末尾的辅音字母不 用双写。 ★★5.大部分双音节词和多音节的词(即音标中含有三个或三个以上元音音素的词)，要在前面加more，most 1 / 5
特别提醒：由ing分词和ed分词演变过来的形容词(talent—talented)只能加more或most来表示它们的比较级和最高级。 特别提醒：★比较级前最常见的修饰词是：much，a little, even 等。★very, quite, too修饰原级。 （二）不规则变化 ★little-less-least用来修饰不可数名称，若修饰可数名称复数则用few-fewer- fewest; ★elder仅用于同辈之间的排行。“年长的”。如: elder brother(哥哥/ 兄长)；elder sister（姐姐）；elder boy（长子）；elder sister（长女）。 在有than的句子中，只能用older。 【归纳大荟萃】 形容词副词的比较级和最高级用法口诀 一者比较用原级，两者相比比较级，三者或以上最高级； 比较级，还是最高级？往往由他们来决定：有than就用比较级； i n或of最高级；若是没有这三词，那就看句意来定。 比较级和最高级变化口诀 原级变成比较级,er结尾要牢记；规则变化要牢记，特殊规则有三条：1．若是以e来结尾，只加r就可以；2.两辅（辅音字母）夹一元（元音字母）结尾的，双写末尾的辅音，最后再加er； 3. 辅音字母若加y，要先把y变成i，最后再加er。（还有一条要 注意：形容词+ l y结尾的，根本不合这一条。）若不符合这三条，直接就加er。其余双音、多音节,词前加more就可以；不规则词没几个,它们需要特殊记。总共就有这五组：好坏多少加上远。 变最高级,也容易, 原级后加est, 规则类同比较级, 提醒一点便可以；其余双音、多音节,词前加most就可以。还有一点要留意, 最高级前要用the；若是副词最高级, 用不用the皆可以。 二、句子构成： 1.当两者比较时，用句型： 2 / 5
