在中考單項選擇中形容詞也占一定比例，一般考查有關(guān)形容詞或副詞的一些搭配，但絕大部分考查形容詞與副詞的比較級和最高級。

　　一、形容詞和副詞的比較級和最高級

　　①一般的比較級和最高級在形容詞或副詞后加-er或-est，如：small —— smaller —— smallest

　　②以不發(fā)音-e結(jié)尾的形容詞或副詞直接加 –r或 –st，如large —— largest —— largest

　?、壑刈x閉音節(jié)詞尾是一個輔音字母的，需雙寫該輔音字母，再加-er或-est.

　?、芤暂o音字母加 y 結(jié)尾的形容詞和副詞，把“y”變“i”，再加 –er或-est.busy——busier——busiesthappy——happier——happiest

　　但一些雙音節(jié)及多音節(jié)形容詞或副詞前要加more和most，如：slowly —— more slowly —— most slowlydifficult——more difficult——most difficultbeautiful——more beautiful——most beautiful; 但還有一些不規(guī)則的變化：good / well——better——bestmany——more——mostbad / ill / badly ——worse——worstlittle——less——leastfar —— farther / further —— farther / furthest

　　二、形容詞和副詞的等比句型

　?、賏s…as… 和……一樣 I’m as tall as you.

　?、趎ot as(so)…as 不和…… 一樣(在否定句中常用so 來代替as)

　　如，I can’t run so fast as you.

　　另外as…as possible 為固定結(jié)構(gòu)，如，as soon as possible， as quickly as possible 等。

　　在以上兩個句型中形容詞或副詞一定要用原級。

　　三、形容詞和副詞的其它句型還有：

　?、傩稳菰~/ 副詞 比較級 + than 句型 ，在than 后面的人稱代詞 用主語和賓語均可。He is older than I / me. 但是如果人稱代詞后有動詞時，則只能用主格形式。如， Tom found more red leaves than I did.

　?、凇皌he + 比較級， the + 比較級” 結(jié)構(gòu)表示兩個變化一起發(fā)生。如， The more you learn， the more you’ll know.

　?、邸癿ore and more”結(jié)構(gòu)(指兩個形容詞比較級用and 連接)表示持續(xù)不斷的變化。 如： I’m getting thinner and thinner.

　　四、修飾形容詞和副詞的比較級的副詞要用much， a lot， a little， a bit， far等，very不能和比較級連用。如： The blouse I bought yesterday is a little less expensive. 昨天我買的襯衣比較便宜。To play basketball is far more enjoyable to the boy. 打籃球?qū)τ谀泻⒆觼碚f要有趣得多。
