课时四形容词的级我们在对两个或以上的人或物进行对比时，则要使用比较或最高级形式。

构成如下：一）一般在词后加er或est(如果是以e结尾则直接加r或st)。

如：greater-greatest, shorter –shortest, taller –tallest, longer –longest, nicer- nicest, larger -largest 二）以重读闭音节结尾且1个元音字母＋1个辅音字母(字母组合除外，如few-fewer fewest)结尾的双写结尾的辅音再加er /est。

如：big-bigger biggest, red-redder reddest, hot-hotter hottest三）以辅音字母＋y结尾的变y为i加er/est。

如：happy-happier happiest, sorry-sorrier sorriest, friendly-friendlier friendliest(more friendly most friendly), busy-busier busiest, easy-easier easiest 四）特殊情况：(两好多坏，一少老远)good/well - better best many/much - more most bad/ill –worse worstlittle- less least old- older/elder oldest/eldest far- farther/further farthest/furthest五）其它双音节和多音节词皆在前面加单词more和most。

【例】careful more careful most careful di fficult more difficult most difficult deliciou s more delicious most delicious二、形容词各等级的用法：1、原级（同级）比较：as…as…; not as(so)…as…We’ll give you as much help as we can.She isn’t as(so)active in sports as before.2. 比较级：表示两者之间比…… 更……可用状语much, a little, even 等修饰： He made fewer mistakes than I did.He is even richer than I.3、高级：形容词最高级前必须加the, 副词最高级前常省略the，后面多用of……，in……短语表示范围：It was the most/least interesting story I have ever listened.He is the tallest of the three.4、如果在两者之间表示“最……”时要在比较级前加the，而且还用of the two, of the pair短语：John is the clever of the two boys.Of the two boys, John is the clever.三、重点与难点：1、as…as…结构：你和汤姆是一样好的孩子。

You’re a boy as good as Tom.=You’re as good a boy as Tom.2、形容词原级表示比较级含义：约翰不象迈克那么苯。

John is not so stupid as Mike.John is less stupid than Mike.John is cleverer than Mike.3、用比较级表示最高级：约翰是班里最高的男生。
