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)成比較級或-est構(gòu)成最高級.如：原級比較級最高級

比較級和最高級。原級比較級最高級

nice———nicer–———nicestfine———finer————finestlarge——larger————largest3)重讀閉音節(jié)詞末尾只有一個輔音字母時,先雙寫這個輔音字母,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：

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

Theyranquitefast.它們跑得相當快。

Theweatherlooksratherbad.

天氣看上去相當糟

Iamsohappy.我是如此的快樂。原級的用法表示兩者之間沒有差別時,使用句型：

主語(第一個人物)+謂語動詞+as+形容詞/副詞原級+as+第二個人物+….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。表示第一個人比不上第二個人時,使用句型:

主語(第一個人物)+謂語動詞(否定式)+as/so+形容詞/副詞原級+asHe

講述兩者有差異,第一個人物超過第二個人物時用比較級?；揪湫停褐髡Z(‘A’)+謂語動詞+形容詞/副詞比較級+than+主語(‘B’)+….

e.g.A

現(xiàn)代的火車比轎車快多了。

這本書花費我的錢不比那本多。

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

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

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

Heismuchmoreseriousthan

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