七年級英語語法：形容詞和副詞

　　在中考單項選擇中形容詞也占一定比例，一般考查有關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以不發音-e結尾的形容詞或副詞直接加 –r或 –st，如large —— largest —— largest

　　③重讀閉音節詞尾是一個輔音字母的，需雙寫該輔音字母，再加-er或-est.

　　④以輔音字母加 y 結尾的形容詞和副詞，把“y”變“i”，再加 –er或-est.busy——busier——busiesthappy——happier——happiest

　　但一些雙音節及多音節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

　　①as…as… 和……一樣 I’m as tall as you.

　　②not 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 為固定結構，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：

　　①形容詞/ 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.

　　②“the + 比較級， the + 比較級” 結構表示兩個變化一起發生。如， The more you learn， the more you’ll know.

　　③“more and more”結構(指兩個形容詞比較級用and 連接)表示持續不斷的變化。 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. 打籃球對于男孩子來說要有趣得多。

　　五、形容詞的一些搭配，

　　如：be glad / happy/ pleased to do 很高興做某事be sorry to do 很抱歉，很遺憾做某事be sure to do 一定/相信會做某事be ready to do 準備好做某事，樂于做某事get ready to do 為……做好準備等等。
