1、形容词、副词比较级和最高级变化形式及用法大多数形容词和副词有比较级和最高级的变化，即原级、比较级和最高级，用来表示事物的等级差别。一、 原级即形容词的原形，比较级和最高级有规则变化和不规则变化两种。规则变化 1. 一般情况在后面直接加-er , -est原级 比较级 最高级tall taller tallestsmart smarter smartest特别提醒：以-y,-er, -ow, le 结尾的双音节形容词末尾加 er 和 est。如：healthy, funny, busy, hungry, easy, happy, early, pretty, lazy, heavy, dirty
2、, clever, narrow 等。 2. 以不发音的 e 结尾只加-r，-st原级 比较级 最高级nice nicer nicestfine finer finest3.“以辅音字母+y”结尾的词改 y 为 i，再加-er, -est原级 比较级 最高级easy easier easiestpretty prettier prettiesthappy happier happiest3. 以一个元音加一个辅音字母结尾的单音节词（即重读闭音节词），双写结尾的辅音字母，再加-er，-est原级 比较级 最高级slim slimmer slimmestthin thinner thinnesth
3、ot hotter hottestbig bigger biggest特别提醒：new, few, slow, clean 等词含有字母组合，且发的是长元音，不用双写。5.大部分双音节词和多音节的词(即音标中含有三个或三个以上元音音素的词)，要在前面加 more，most特别提醒：以形容前缀 un 构成的三音节形容词不适合上述情况，如 unhappy-unhappier-unhappiest,untidy-untidier-untidiest 6.以形容词+ly 构成的副词要在前面加 more，most原级 比较级 最高级slowly more slowly most slowlyquickl

6、esting二、形容词比较级构成方法的记忆歌诀：两者之间作比较，尾巴 er 少不了；一般词尾加 er，有 e 词尾加 r；单一辅音单音节，双写词尾加 er辅音加 y 很重要，去 y 变 i 加 er遇到双音和多音,最高级 most 放前最合适。三、形容词、副词比较级和最高级部分用法歌诀：1. 两者和三者、三者以上：两者比较用 than 连接，三者比较 the 在前；2. 同级比较歌诀：同级比较用原级 asas 永不离，若是否定加 not asas 否在前asas 加 not 只说两者有区别soas 加 not 后者总是强前者3.比较级前常可放以下表修饰和程度的词： a little 稍微, m
7、uch 得多, even 更、还要， far 得多, still 要、还要, a lot, 得多 rather 相当。四、形容词和副词比较级、最高级的用法级别 比较程度 表达方式和意义原级1. 同等比较的肯定形式2. 同等比较的否定形式as+原级+as （像一样）not+so/as+原级+as比较级1. 不同程度（用于两者比较）2. 不同比较（程度加深）比较级+than+ 比较级1） 比较级+and+ 比较级：越来越2） the+比较级，the+比较级（越 越）最高级最高级最高程度（用于三者或三者以上）the+最高级+of/in+范围强调：定冠词在形容词最高级中使用但是在副词最高级中往往省略不
