1.構(gòu)成的不規(guī)則變化:2.構(gòu)成的規(guī)則變化:形容詞和副詞的比較級(jí)1.構(gòu)成的不規(guī)則變化:e.g.good/well–better–best

bad/badly–worse–worst

many/much–more–most

little–less–least

far–farther/further–farthest/furthest2.構(gòu)成的規(guī)則變化:1)單音節(jié)詞和少數(shù)雙音節(jié)詞一般在詞尾后加-er構(gòu)成比較級(jí)或-est構(gòu)成最高級(jí).如：原級(jí)比較級(jí)最高級(jí)

cold–——colder–——coldest

bright———brighter———brightestyoung——younger——youngest2)以字母

e結(jié)尾的詞只加–r

或-st

構(gòu)成

比較級(jí)和最高級(jí)。原級(jí)比較級(jí)最高級(jí)

nice———nicer–———nicestfine———finer————finestlarge——larger————largest3)重讀閉音節(jié)詞末尾只有一個(gè)輔音字母時(shí),先雙寫(xiě)這個(gè)輔音字母,再加-er或-est。如:big–bigger–biggestthin–thinner–thinnest4)以“輔音字母+y”結(jié)尾的雙音節(jié)詞，先改y為i,再加-er或-est。如：

easy–easier–easiesthappy–happier–happiest5)多音節(jié)詞和部分雙音節(jié)詞在詞前加more

或most。如：

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

講述某人或某物自身情況時(shí)用原級(jí)?；揪湫停褐髡Z(yǔ)+謂語(yǔ)+形容詞/副詞原級(jí)+….Heisveryoldnow.他現(xiàn)在很老了。

Theyranquitefast.它們跑得相當(dāng)快。

Theweatherlooksratherbad.

天氣看上去相當(dāng)糟

Iamsohappy.我是如此的快樂(lè)。原級(jí)的用法表示兩者之間沒(méi)有差別時(shí),使用句型：

主語(yǔ)(第一個(gè)人物)+謂語(yǔ)動(dòng)詞+as+形容詞/副詞原級(jí)+as+第二個(gè)人物+….如：Heisasexcitedashisyoungersister.

他和他妹妹一樣興奮。

Lilyrodeherbikeasslowlyasanoldlady.莉莉騎車像老太太一樣慢。

Theypickedasmanyapplesasthefarmers(did).他們摘的蘋果和農(nóng)民一樣多。表示第一個(gè)人比不上第二個(gè)人時(shí),使用句型:

主語(yǔ)(第一個(gè)人物)+謂語(yǔ)動(dòng)詞(否定式)+as/so+形容詞/副詞原級(jí)+asHe

講述兩者有差異,第一個(gè)人物超過(guò)第二個(gè)人物時(shí)用比較級(jí)。基本句型：主語(yǔ)(‘A’)+謂語(yǔ)動(dòng)詞+形容詞/副詞比較級(jí)+than+主語(yǔ)(‘B’)+….

e.g.A

modern

This

這本書(shū)花費(fèi)我的錢不比那本多。

比較級(jí)的用法在形容詞比較級(jí)前還可用much,even,still,alittle來(lái)修飾,表示“……的多”,“甚至……”,“更……”,“……一些”。e.g.1)Thiscityismuchmorebeautifulthanbefore.2)She’salittlemoreoutgoingthanme.3)It’salittlecoldertoday.

3.“比較級(jí)＋and＋比較級(jí)”意為“越來(lái)越……”。多音節(jié)比較級(jí)用“moreandmore＋形容詞原級(jí)”形式。如：It’sgettingworseandworse.Thegroupbecamemoreandmore

popular.4.“Which/Whois+比較級(jí)…？”比較A、B兩事物,問(wèn)其中哪一個(gè)較……時(shí)用此句型。如：WhichT-shirtisnicer,thisoneorthatone?Whoismoreactive,MaryorKate?Whichoneismorepopularamongstudents,goingtoconcertsorgoingtomovies?5.使用形容詞比較級(jí)時(shí)需注意以下幾點(diǎn)：1)than后面接代詞時(shí),一般要用主格形式，但在口語(yǔ)中也可使用賓格形式。如：MybrotheristallerthanI/me.2)當(dāng)需要表示一方超過(guò)另一方的程度時(shí)，可以用much,alot,alittle,abit,even,still等來(lái)修飾形容詞比較級(jí)。注意:比較級(jí)不能用very,so,too,quite等修飾。如：

Heismuchmoreseriousthan

Sam.3)形容詞比較級(jí)后面往往用連詞than連接另一個(gè)比較的人或事物,但在上下文明確的情況下,形容詞比較級(jí)可單獨(dú)使用。如：Mysisteristall,butmyauntistaller.我姐姐個(gè)子高,但我姑姑個(gè)子更高。4)進(jìn)行比較的人和物必須是同一類。
