1 形容词的比较级和最高级

2 请你思考：什么是形容词？ 形容词用于修饰名词，表示人或事物的 属性或特征等。

3 形容词的级别 大多数形容词有三个等级： 原级 比较级 最高级

请你观察：形容词比较等级的变化规律 long longer longest nice nicer nicest big bigger biggest early earlier earliest interesting more interesting most interesting carefully more carefully most carefully friendly more friendly most friendly friendlier friendliest good better best many/much more most 原级 比较级 最高级

5 请你总结：形容词比较等级构成的规律 一. 规则变化： 1.单音节和部分双音节词,在词尾直接加-er,-est 2.以字母e结尾的,加-r,-st 3.以重读闭音节结尾且末尾只有一个辅音字母， 双写此字母,再加-er,est 4.以“辅音字母+y”结尾的，把y变成i，再加- er,est 5.多音节词和大部分双音节词,在词的前面加more 或most 6.有些双音节词既可用more,most形式，又可用- er,-est形式 二. 不规则变化

6 请给出下列形容词的比较级和最高级 tall near large able thin hot funny happy beautiful
quickly quiet little taller tallest nearer nearest larger largest abler ablest thinner thinnest hotter hottest funnier funniest happier happiest more beautiful most beautiful more quickly most quickly quieter quietest more quiet most quiet less least

7 一，要双写再加-er,-est的词有哪些？
请你牢记： 一，要双写再加-er,-est的词有哪些？ hot big fat thin red wet sad glad … 二. 不规则变化的词有哪些？ 原级 比较级 最高级 good/well better best bad/ill/badly worse worst many/much more most little less least old older oldest elder eldest far farther farthest further furthest

8 温馨提示： 类似 slowly, quickly 这样的双音节词，虽然也是辅 音字母加y结尾，但这里的 -ly 是表示后缀，因
此比较级和最高级的构成是在单词前加more和most。 2. 强调程度时，形容词前可加上too,very,so, quite等。比较级前则要加上much, even, a little, a lot, still, a bit 等词(组)，表示程度。 3. farther 常指时间、距离上的远。further可以代替 farther，还常用于引伸和抽象的意义，表示“进一步， 更深刻，更深入等”。 4. older表示年龄大小或年代的久远，elder表示兄弟姐 妹之间的长幼关系。

9 形容词原级的用法： 用来直接描述人物或动作。 John is a tall boy. Rabbits run fast.
Our country is beautiful and strong. 2. … as + 原级 + as … “……和……一样” You are as tall as me. = You are as tall as I (am). He has as many books as I (have). This computer runs as fast as that one. 3.… not as(so) + 原级 + as … “……不如/没有……” This jacket is not as(so) cheap as that one. She has not as(so) many books as I have. Henry doesn’t study as(so) hard as his elder brother. 注：as在这里既可作介词又可作连词。作介词时，后接人称代词的宾格。作连词时，后接一个省略的比较状语从句。

10 形容词比较级的用法： 1. … 比较级 + than … “……比……更……”
You are taller than me. = You are taller than I (am).
