聚焦形容词与副词的比较概述：大多数形容词与副词有三个级：原级（即原形）、比较级与最高级。
形容词与副词按变化可以分为规则形容词词与副词与不规则形容词词与副词规则I.形容词词与副词的比较级与最高级变化规则如下：一．所有单音节与部分双音节如何变比较级与最高级1 一般在词末尾加er变比较级，加est变最高级strong —stronger -strongest small--smaller--smallest hard→harder →hardest fast→faster →fast est2 如果以e结尾，只加r 与stnice--nicer--nicest fine--finer--finest3 以重读闭音节，末尾只有一个辅音字母，须先双写这个辅音字母，再加er与estsad--sadder-- saddest big--bigger--biggest hot--hotter --hottest4 以辅音字母加y结尾的词，把y变成i，再加er与est，angry--angrier-angriest early→earlier →earl iest hungry-hungrier-hungriest但是，开放类副词即形容词加ly结尾变成的副词加more或most.如quickly →more quickly →most quickly quietly →more quietly →most quietlyslowly—more slowly—most slowly［注］：early中的ly不是后缀，故把y变i再加er与est二大部分双音节与所有多音节词都在其前面加more变比较级，加most变最高级different -more different -most differentbeautiful--more beautiful--the most beautifulexpensive--more expensive--the most expensive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三，不规则形容词与副词的比较级与最高级good / well -- better-- best badly/bad / ill -- worse -- worstmany/ much-- more--most little -- less-- least far-- farther--farthest 或further--furthestII，形容词与副词的原级、比较级与最高级的基本用法一、原级比较的基本用法：原级比较由“….as＋形容词或副词原形＋as…”构成译：前者与后者一样eg:Alice is as tall as her younger sister.爱丽丝与她妹妹一样高Liu Dehua sings as well as Joy Zhou刘德华与周杰林伦唱得一样好。

形容词副词比较级最高级变化规则及用法形容词的比较级和最高级的变化规则如下：1. 一般情况下，在形容词的原级后加-er作为比较级，加-est作为最高级。
例如：原级：tall（高）比较级：taller（更高）最高级：tallest（最高）2. 以字母“e”结尾的形容词，在原级后只加-r作为比较级，加-st作为最高级。
例如：原级：large（大的）比较级：larger（更大的）最高级：largest（最大的）3. 以元音字母加辅音字母结尾的单音节形容词，在原级后双写最后一个辅音字母，再加-er作为比较级，加-est作为最高级。
例如：原级：hot（热的）比较级：hotter（更热的）最高级：hottest（最热的）4. 以辅音字母加-y结尾的形容词，在原级中把-y改为-i，再加-er作为比较级，加-est作为最高级。
例如：原级：funny（有趣的）比较级：funnier（更有趣的）最高级：funniest（最有趣的）副词的比较级和最高级的变化规则如下：1. 大多数副词在前面加more形成比较级，在前面加most形成最高级。
例如：原级：quickly（快速地）比较级：more quickly（更快速地）最高级：most quickly（最快速地）2. 以字母“e”结尾的副词，在前面只加-r形成比较级，加-st形成最高级。
例如：原级：late（迟）比较级：later（更迟）最高级：latest（最迟）3. 以字母“y”结尾的副词，在前面把-y改为-i，再加-er形成比较级，加-est形成最高级。
例如：原级：busy（忙碌地）比较级：busier（更忙碌地）最高级：busiest（最忙碌地）需要注意的是，有些形容词和副词的比较级和最高级形式并不遵循以上的规则，而是需要记忆。
例如：good（好的）- better（更好的）- best（最好的）, well（好地）- better（更好地）- best（最好地）。
形容词和副词的比较级和最高级一. 形容词和副词的比较级和最高级的变化方法如下:(1) 规则变化表：(2)几个不规则的形容词和副词的比较级和最高级如下表：二．形容词和副词比较级的基本用法三．形容词副词比较级最高级的特殊用法（1）和冠词连用the ＋形容词原级＋v(复)，指一类人或物the ＋形容词比较级，指两者中“较…的”的那一个，eg. the younger of the twoa/ an ＋形容词比较级eg. The pen is expensive. I want a cheaper one.a＋most不是最高级相当于very，修饰其后的名词“非常…”eg. a most beautiful city the+most表示最高级the most wonderful movie（2）序数词与最高级连用，如：Flying is the fastest and the second cheapest way to travel.（3）比较级＋than any other ＋n. （单）（适用于范围一致时）(all) other ＋n.（复）any ＋n.(单) （适用于范围不一致时）any other student / all other students in his class.他是他们班最高any student in my class.他比我们班上任何一个同学都高。
（4）倍数表达法。
1. 倍数+ as + 形容词或副词的原级+ as + 其他。
这种结构又常演变成下列两类：①倍数+ as + many + 可数名词复数+ as；②倍数+ as +much + 不可数名词+ as。
如：There are seven times as many people as I expected.是我预料的人数的七倍。
There is five times as much coffee in this glass as in that one.这个杯子里的咖啡是那个杯子里的五倍。
可编辑修改精选全文完整版形容词、副词的比较级与最高级用法详解一、形容词、副词比较级、最高级构成大多数的形容词、副词都具有原级、比较级和最高级三种形式。
而形容词、副词的比较级、最高级构成方式分规则变化和不规则变化。
其规则变化的方式详见下面个表：（一）规则变化：(1) 直接在词尾加-er, -est(2) 以不发音字母e 结尾的，在词尾加-r , -st(3)以“辅音字母+y“结尾的，把y 变i，再加-er , -est(4) 以辅音字母结尾的重读闭音节词汇，双写最后一个辅音字母，再加-er , -est(5) 部分双音节和多音节词，在其前加more, most（二）、不规则变化：比较级、最高级具有不规则变化形式的形容词和副词比较少，因此，需要大家逐一认真记忆。
详见下表：【妙记顺口溜】“坏”“病”两“多”和两“好”，一是“远”来,二是“老”，little 是“少”不是“小”。
二、形容词、副词比较级和最高级用法（一）形容词、副词比较级用法形容词、副词的比较级主要对两个的人或物在某种程度、性质上进行比较。
常见的形容词副词比较级用法如下：1.同级比较① A+be/v+as+原级+as+B A和B一样This room is as large as that one .这间房子和那间一样大(形容词)Tom writes as carefully as Kate.汤姆写字跟凯特一样认真。
(副词)②A+be/V+not+as(so)+级+as +B A 不如BTigers aren't as(so) dangerous as lions.老虎不如狮子危险。
(形容词)Mary didn't finish the work as(so) well as Lucy.玛丽完成这项工作不如露西好。
(副词)2.差极比较①A+be/v+比较级+B A比B更......This pen is newer than that one.这支钢笔比那支新。
