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(A)+谓语动词+as+形容词/副词原级+as+B+….如：Heisastallashisyoungersister.

Lily’shairisaslongashermother.表示第一个人比不上第二个人时,使用句型:

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’salittlefatterthanme.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.4)进行比较的人和物必须是同一类。
