初中英语比较级和最高级总结

绝大多数形容词有三种形式,原级,比较级和最高级, 以表示形容词说明的性质在程度上的不同。

形容词的原级: 形容词的原级形式就是词典中出现的形容词的原形。例如:poor tall great glad bad

形容词的比较级和最高级: 形容词的比较级和最高级形式是在形容词的原级形式的基础上变化的。分为规则变化和不规则变化。1)单音节形容词的比较级和最高级形式是在词尾加-er 和-est 构成。great(原级)(比较级)(最高级)

2)以-e 结尾的单音节形容词的比较级和最高级是在词尾加-r 和-st 构成。wide(原级)(比较级)(最高级)

3)少数以-y,-er,-ow,-ble结尾的双音节形容词的比较级和最高级是在词尾加-er 和-est 构成。

clever(原级)(比较级)(最高级)

4)以-y 结尾,但-y 前是辅音字母的形容词的比较级和最高级是把-y 去掉,加上-ier 和-est 构成.happy(原形)(比较级)(最高级)

5)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。

big(原级)(比较级)(最高级)

6)双音节和多音节形容词的比较级和最高级需用more 和 most 加在形容词前面来构成。

beautiful(原级)?(比较级)(比较级)difficult(原级)(最高级)(最高级)

常用的不规则变化的形容词的比较级和最高级:原级------比较级------最高级good------better------bestmany------more------mostmuch------more------mostbad------worse------worst

far------farther, further------farthest, furthest形容词前如加 less 和 least 则表示“较不”和"最不

形容词比较级的用法:

形容词的比较级用于两个人或事物的比较,其结构形式如下:

主语+谓语(系动词)+ 形容词比较级+than+ 对比成分。也就是, 含有形容词比较级的主句+than+从句。注意从句常常省去意义上和主句相同的部分, 而只剩下对比的成分。

形容词最高级的用法:

形容词最高级用于两个以上的人和物进行比较, 其结构形式为:主语+谓语(系动词)+the+形容词最高级+名词+表示范围的短语或从句

形容词比较级和最高级的用法总结篇2

1)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末尾加-er,-est tall(高的) taller tallest great(巨大的) greater greatest

2)以不发音的e结尾和以- le结尾的双音节词只加-r,-st nice(好的) nicer nicest ，

able(有能力的) abler ablest

3)以一个辅音字母结尾的闭音节单音节词，双写结尾的辅音字母，再加-er，-est big(大的) bigger biggest hot热的) hotter hottest

4)“以辅音字母+y”结尾的双音节词改y为i，再加 -er，-est

easy(容易的) easier easiest ，

busy(忙的) busier busiest

5)少数以-er，-ow 结尾的双音节词末尾加-er，-est clever(聪明的) cleverer cleverest narrow(窄的) narrower narrowest

6)其他双音节词和多音节词，在前面加more，most 来构成比较级和最高级

important(重要的) more important most important easily(容易的) 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

3.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 cleverer 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 country 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。

二、用所给词的适当形式填空

通过比较级和最高级表示否定意义篇5

1.know better than+不定式。这种结构意为“不至于”：

She knows better than to go alone on such a night.

在这样的夜晚，她不至于连不宜单独外出也不知道。

know better than to do sth.的含义是be wiser,better informed,or more sensible than to do or believe sth.

以此类推，下列三句有类似意义，如：

I am wiser than to believe that.

我不至于蠢到竟然相信这件事。

You have a better command of French than to make such mistakes.

你的法语较好，不至于犯这样的错误。

He is more experienced than to do such a thing.

他比较有经验，不至于做这样的事。

2.more than…can。这种句型形式上是肯定，实际上有否定含义，如：

The boys in the street have become very insolent and it is more than flesh and blood can bear.

街上的男孩变得非常无礼,到了人所不能忍受的地步。

The beauty of the place is more than I can describe.

那地方美得无法形容。

This is more than I can tell.

这我简直不懂。

He has bitten off more than he can chew.

他承担了力所不及的事。

3.用the last，the least等最高级形式表示强烈的否定意义，如：

He would be the last man to say such things.

他决不会说这样的话。

This is the last place where I expected to meet you.

我万万没有想到会在这儿碰上你。

That was the least of his worries.

形容词比较级和最高级变化规则1 篇6

形容词级的变化规律和级的用法:

一、形容词级的变化：

1、规律变化：

单音词的变化：（四条）

①一般情况： +er(比较级)+est(最高级)eg :quiet--quieter--the quietest

bright--brighter---the brightest 明亮/聪明的dear--dearest--the dearest clever--cleverer--the cleverest ②词末为--e（不发音）+ r--+st eg:fine--finer--the finest nice--nicer--the nicest cute--cuter--the cutest close--closer--the closest white--whiter--the whitest large--larger--the largest free--freer--freest(特殊)

③重读闭音节，末尾只有一个辅音字母的：

thin--thinner--the thinnest fit--fitter--fittest

④少数以辅音字母+y结尾的双音节原根词：

变y为i+er 变y为i+est

形容词和副词用法比较

形容词和副词形容词和副词在语法结构中主要用于比较级和最高级。形容词和副词的构成形式基本上一样，它们的形式与单音节、双音节和多

音节有关，当然还有其特殊形式。形容词和副词比较级的基本用法分为同级比较、比较级和最高级三种形式。但这三种形式都有它们特殊的表达方式以及它们的惯用法。对以下要点大家须一一掌握。

第一节形容词比较级和最高级的形式

一、形容词比较级和最高级的构成

形容词的比较级和最高级变化形式规则如下

构成法原级比较级最高级

① 一般单音节词末尾加er 和 est strong stronger strongest

② 单音节词如果以e结尾，只加r 和st strange stranger strangest

③ 闭音节单音节词如末尾只有一个辅音字母，须先双写这个辅音字母，再加er和est sad big

hot sadder bigger

hotter saddest biggest hottest

④ 少数以y,er(或ure),ow,ble结尾的双音节词，末尾加er和est(以y结尾的词，如y前是辅音字母，把y变成i，再加er和est，以e结尾的词仍

只加r和st)angry clever narrow

noble angrier cleverer narrower

nobler angrest cleverest narrowest noblest

⑤ 其他双音节和多音节词都在前面加单词more和most different more

different most different

1)The most high 〔A〕 mountain in 〔B〕 the world is Mount Everest，which is situated 〔C〕 in Nepal and is

twentynine thousand one hundred and fourty one feet high 〔D〕.2)This house is spaciouser 〔A〕 than that 〔B〕 white 〔C〕 one I bought in Rapid City，South Dakota 〔D〕 last year.3)Research in the social 〔A〕 sciences often proves difficulter 〔B〕 than similar 〔C〕 work in the physical 〔D〕 sciences.二、形容词比较级或最高级的特殊形式：

1.三个或三个以上音节的形容词只能加more和most

只能说 more beautiful而不能说beautifuller;只能说the most beautiful而不能说beautifullest。

但是，以形容前缀un结尾的三音节形容词不适合上述情况，如unhappy,untidy，我们可以说：unhappier→unhappiest, untidier→untidiest

2.由ING分词和ED分词演变过来的形容词(包括不规则动词如know→known)只能加more或most来表示它们的比较级和最高级

more(most)striking, more(most)interesting, more(most)wounded, more(most)worn等。

4)The drawings 〔A〕 of the old masters 〔B〕 are among the treasuredest 〔C〕 works in museums 〔D〕.3.英语里有些形容词由于其词义而不可能有比较级形式

absolute fatal main right universal chief final naked simulta-utter entire foremost perfect neous vital

eternalinevitablepossiblesufficientwhole excellent infinite primary supreme wooden

三、不规则形容词的比较级和最高级形式

good

well betterbest bad

illworseworst

many

much moremost little

few lessleast far fartherfarthest furtherfurthest

5)African elephants are larger，fiercer，and difficulter 〔A〕 to tame 〔B〕 than 〔C〕 Asian elephants 〔D〕.6)Sarah Hale became 〔A〕 one of the famousest 〔B〕

magazine 〔C〕 editors in the United States during 〔D〕 the 1800’s.7)Of all 〔A〕 the Native American tribes 〔B〕，the Shawnee Indians were 〔C〕 a most 〔D〕 transient.四、例题解析

1)A错。应将“most high”改为highest。这是在考形容词比较级的构成形式。

2)A错。改为more spacious。

3)B错。改为more difficult。

4)C错。treasured 在本句中是ED分词(动词treasure ＋ed)作形容词使用，是“宝贵的、珍贵的”意思，修饰名词 works(作品)，其最高级形式应用 the most treasured。

5)A错，改为more difficult。

6)B错。改为“the most famous”，因为famous(著名的)是双音节，其最高级变化应在前面加“the most”。

7)D错。应改为“the most”，因为此处表示的是最高级，“the most transient”意为“(延续时间)最短暂的”。

第二节副词比较级和最高级的形式

副词比较级和最高级的变化形式与形容词基本上一样

一般副词

hard→harder →hardest fast→faster →fastest late→later →latest

early→earlier →earliest

特殊副词

well →better →best much →more →most badly →worse →worst

little →less →least 但是，开放类副词即以后缀ly结尾的副词不能像形容词那样加er或est，如

quickly →more quickly →most quickly quietly →more quietly →most quietly 〔注〕： early中的ly不是后缀，故可以把y变i再加er和est

第三节形容词与副词比较级和最高级的基本用法

一、原级比较的基本用法

1.原级比较由“as＋形容词或副词(或再加名词或短语)＋as ”构成“原级相同”比较句，表示两者比较；其否定式，即“程度不及”比较句型为“not so(as)＋形容词或副词＋as”，而且as…as结构前可用just, almost, nearly, quite等表示程度的词修饰

1)Walking briskly for thirty minutes will burn as many calories as.〔A〕 to run for fifteen minutes 〔B〕 running for fifteen minutes 〔C〕 you run for fifteen minutes 〔D〕 fifteenminute walking 2)The gorilla(大猩猩)，while 〔A〕 not quite as curious than 〔B〕 the chimpanzee(黑猩猩)，shows more persistence 〔C〕 and memory retention(记忆力)in solving 〔D〕 a problem.3)Alaska is twice 〔A〕 as larger 〔B〕 as 〔C〕 the next largest 〔D〕 state，Texas.2.“as(so)＋名词＋as＋名词”进行名词比较，这时一般情况下有一个表示原级的比较词，但如果第一名词前出现了形容词修饰该词或出现副词修饰谓语，应当用so而不用as

4)Thomas Jefferson’s achievements as an architect rival his contributions a politician.〔A〕 such 〔B〕 more 〔C〕 as 〔D〕 than

5)I should say Henry is not much a writer as a reporter.(88

年考题)〔A〕 that 〔B〕 so 〔C〕 this 〔D〕 as

二、比较级

1.比较级由“形容词(副词)比较级＋than＋…，”构成表示在两者中间一方比另一方“更加…”。连词than后可接句子，也可接名词、代词、名词短语、介词短语、动词、动词不定式、ING结构和ED结构，有时也可省去than。

6)Natural mica(云母)of 〔A〕 a superior 〔B〕 quality is cheapest 〔C〕 to obtain than synthetic 〔D〕 mica.7)She is older than.〔A〕 any other girl in the group 〔B〕 any girl in the group 〔C〕 all girls in the group

〔D〕 you and me as well as the group

8)Josephine McCrackin joined 〔A〕 the “Santa Cruz Sentinel” in 1905 and，until her death fifteen years late 〔B〕，remained 〔C〕 active in journalistic 〔D〕 work.2.注意than前后两项相比较的人或事物要一致

9)The purpose of the research had a more important meaning for them than.〔A〕 ours 〔B〕 with us

〔C〕 for ours it had 〔D〕 it did for us 10)Sound travels air.〔A〕 faster through water than through 〔B〕 faster than through water and

〔C〕 through water faster and〔D〕 where it is faster through water than through

11)Gerbrand von den Feckhout，one of Rembrand’s pupils，followed 〔A〕 the style of his teacher so implicitly that 〔B〕 his paintings 〔C〕 are sometimes confused with his master 〔D〕.三、最高级

1.最高级用于三者以上比较，形容词的结构形式是“定冠词＋形容词最

高级＋名词＋表示范围的短语或从句”(如all, of all, of the tree, in the world, that has ever taken place等)

12)The more 〔A〕 fearsome of all the 〔B〕 animals in 〔C〕 the Western 〔D〕 Hemisphere is the grizzly bear.13)Of all economic 〔A〕 problems，inflation continues to be 〔B〕 a 〔C〕 most significant in its daily impact on 〔D〕 people and business.14)，the most familiar to general public is the criminal jurisdiction.〔A〕 All the activities 〔B〕 The activities

〔C〕 Of all the activities 〔D〕 It is the activities

2.副词的最高级与形容词最高级的区别在于最高级前没有定冠词the

四、例题解析

1)B为正确答案。

2)B错。改为 as，和前面的as和形容词原形curious 一起构成同程度比较。

3)B错。改为as large。

4)C对。动词rival(胜过、匹敌)前后是两个相比较的成分achievements(成果)和 contributions(贡献)，由于前面的名词后出现了短语 as an architect，故空白处也应用as，使前后对比成分一致。

5)B为正确答案。

6)C错。应改为比较级cheaper。比较级后并不一定跟接连词than，有时在其间有名词或名词短语(被形容词所修饰)，介词短语，不定式或其他成分隔开。

7)A为正确答案。“She”作为单个不能跟全组比(C和D不对)，也不能跟全组所有相比，因为“她”也是其中一员，自然“她”不能跟自己相比。这里“She”比较的是“这组中的任何一个”，所以A对。

8)B错。应改为比较级later，因此处实为与1905年相比晚15年，故应使用比较级。

9)D为正确答案。

10)A为正确答案。

11)D错。改为his master’s。

12)A错。改为most。

13)C错。改为the，significant是多音节形容词，在此处应用最高级形式(在前面加 the most)，注意句中的“of all… ”。

14)C为正确答案。本句空白处缺状语，A和B全为名词短语，不符合

条件；D为句子，和空白后面的句子没有任何联系，故亦应排除。只有C正确，和后面的最高级the most familiar前后呼应。

第四节形容词和副词的特殊表达法

一、形容词与副词的同级比较：由“as(so)…as”引出，其否定式为“not so…”或“not as…as”,考生还应注意下列含有“as”结构或短语的句子

1.as such：表示上文所指明的事或人

He is a child,and must be treated as such.他是个孩子，必须被当作孩子对待。

2.as much：表示“与…同量”

Take as much as you like.拿多少都行。

I would gladly have paid twice as much for it.就是价格再贵一倍，我也会愿意把它买下的。

He as much as admitted the whole story.他几乎全部承认了。

3.as many：表示“与…一样多”

I found six mistakes in as many lines.我在六行中发现了六个错。

二、表示“几倍于”的比较级：用twice(两倍)，four times(四倍)，ten times(十倍)加上as … as 结构

This one is four times as big as that one.这个是那个的四倍大。(这个比那个大三倍。)/ Our campus is three times as large as yours.我们的校园比你们的大两倍。/ He has books twice as many as she does.他的书比她多一倍。

1)The fiveyear deal obligates 〔A〕 the country to buy nine million tons 〔B〕 of grain a year 〔C〕，three million more as 〔D〕 the old pact’s minimum.三、“the same ＋名词＋as”表示同等比较

2)The lens of a camera performs the lens of the eye.〔A〕 in the same function 〔B〕 the same function as 〔C〕 the function is the same as 〔D〕 and has the same function

3)The elimination of inflation would ensure that the amount of money used in repaying a loan would have as the amount of money borrowed.〔A〕 as the same value 〔B〕 the same value

〔C〕 value as the same 〔D〕 the value is the same

四、比较级前可用a little, a bit, slightly, a great deal, a lot,many, much等词语表示不定量，far, completely,still表示程度或更进一步

4)There are now methods for studying color vision in infants than there once were.〔A〕 more sophisticated than 〔B〕 much more sophisticated 〔C〕 much sophisticated 〔D〕 sophisticated

5)The photographs of Mars taken by satellite are than those taken from the Earth.〔A〕 clearest 〔B〕 the clearest 〔C〕 much clearer 〔D〕 more clearer

6)Common porpoises(海豚)are usually not considered 〔A〕 migratory，although 〔B〕 some do move 〔C〕 to more warmer 〔D〕 waters in winter.兼有两种形式的副词

1)close与closely

close意思是“近”； closely 意思是“仔细地” He is sitting close to me.Watch him closely.2)late 与lately

late意思是“晚”； lately 意思是“最近” You have come too late.What have you been doing lately? 3)deep与deeply

deep意思是“深”，表示空间深度；deeply时常表示感情上的深度，“深深地”

He pushed the stick deep into the mud.Even father was deeply moved by the film.4)high与highly

high表示空间高度；highly表示程度，相当于much The plane was flying high.I think highly of your opinion.5)wide与widely

wide表示空间宽度；widely意思是“广泛地”，“在许多地方” He opened the door wide.English is widely used in the world.6)free与freely

free的意思是“免费”；freely 的意思是“无限制地”

You can eat free in my restaurant whenever you like.You may speak freely;say what you like.形容词使用顺序巧记忆

当两个以上形容词修饰一个名词，形容词该如何排列? 为什么不能说a black new pen，而要说成a new black pen? 这里面有无规则可循?

如果你记住Opshacom这个为帮助记忆而杜撰的词，就能掌握英语中形容词排列的顺序。

Opshacom中op代表opinion，指表示人们观点的形容词，如beautiful，horrible，lovely，nice等；

sh代表shape，指表示形状的形容词，如long，short，round, narrow等；

a代表age，指表示年龄、时代的形容词，如old，new，young等；

c代表colour，指表示颜色的形容词，如red,black, orange等；

o代表origin，指表示国籍、地区的形容词，如British，Canadian，German等；

m代表material，指表示材料的形容词，如plastic，metal，aluminium等。
