1.构成的不规则变化:2.构成的规则变化:形容词和副词的比较级1.构成的不规则变化:e.g.good/well–better–best

bad/badly–worse–worst

many/much–more–most

little–less–least

far–farther/further–farthest/furthest2.构成的规则变化:1)单音节词和少数双音节词一般在词尾后加-er构成比较级或-est构成最高级.如：原级比较级最高级

cold–——colder–——coldestbright———brighter———brightestyoung——younger——youngest2)以字母

e结尾的词只加–r

或-st

构成

比较级和最高级。原级比较级最高级

nice———nicer–———nicestfine———finer————finestlarge——larger————largest3)重读闭音节词末尾只有一个辅音字母时,先双写这个辅音字母,再加-er或-est。如:big–bigger–biggestthin–thinner–thinnest4)以“辅音字母+y”结尾的双音节词，先改y为i,再加-er或-est。如：

easy–easier–easiesthappy–happier–happiest5)多音节词和部分双音节词在词前加more

或most。如：

delicious–moredelicious–mostdeliciousinteresting–moreinteresting–mostinterestingimportant—moreimportant—mostimportant

讲述某人或某物自身情况时用原级。基本句型：主语+谓语+形容词/副词原级+….Heisveryoldnow.他现在很老了。

Theyranquitefast.它们跑得相当快。

Theweatherlooksratherbad.

天气看上去相当糟

Iamsohappy.我是如此的快乐。原级的用法表示两者之间没有差别时,使用句型：

主语(第一个人物)+谓语动词+as+形容词/副词原级+as+第二个人物+….如：Heisasexcitedashisyoungersister.

他和他妹妹一样兴奋。

Lilyrodeherbikeasslowlyasanoldlady.莉莉骑车像老太太一样慢。

Theypickedasmanyapplesasthefarmers(did).他们摘的苹果和农民一样多。表示第一个人比不上第二个人时,使用句型:

讲述两者有差异,第一个人物超过第二个人物时用比较级。基本句型：主语(‘A’)+谓语动词+形容词/副词比较级+than+主语(‘B’)+….

e.g.A

比较级的用法在形容词比较级前还可用much,even,still,alittle来修饰,表示“……的多”,“甚至……”,“更……”,“……一些”。e.g.1)Thiscityismuchmorebeautifulthanbefore.2)She’salittlemoreoutgoingthanme.3)It’salittlecoldertoday.

3.“比较级＋and＋比较级”意为“越来越……”。多音节比较级用“moreandmore＋形容词原级”形式。如：It’sgettingworseandworse.Thegroupbecamemoreandmore

popular.4.“Which/Whois+比较级…？”比较A、B两事物,问其中哪一个较……时用此句型。如：WhichT-shirtisnicer,thisoneorthatone?Whoismoreactive,MaryorKate?Whichoneismorepopularamongstudents,goingtoconcertsorgoingtomovies?5.使用形容词比较级时需注意以下几点：1)than后面接代词时,一般要用主格形式，但在口语中也可使用宾格形式。如：MybrotheristallerthanI/me.2)当需要表示一方超过另一方的程度时，可以用much,alot,alittle,abit,even,still等来修饰形容词比较级。注意:比较级不能用very,so,too,quite等修饰。如：

Heismuchmoreseriousthan

Sam.3)形容词比较级后面往往用连词than连接另一个比较的人或事物,但在上下文明确的情况下,形容词比较级可单独使用。如：Mysisteristall,butmyauntistaller.我姐姐个子高,但我姑姑个子更高。4)进行比较的人和物必须是同一类。
