英语中比较两者时使用比较级，由形容词或副词的原级变化而来。
形容词和副词有三个比较等级，即：1. 原级，也就是原形。2. 比较级，表示“较……”或“更……”的意思。（用于两者之间比较）3. 最高级，表示“最……”的意思。 （用于三者或三者以上的比较）
形容词或副词比较级的构成(规则变化)：
3. 重读闭音节词词尾只有一个辅音字母时，先双写辅音字母再+er
4. 以辅音字母+y结尾的单音节词，变y 为i+er
2. 以不发音的字母e结尾的+r
1. 一般在词尾+er
5. 多音节词和部分双音节词前加mre
tall -- taller
nice -- nicer
fat -- fatter
funny -- funnier
interesting – mre interesting
heavy -- heavier
difficult – mre difficult
形容词或副词比较级的构成(不规则变化)：
比较级，要变化,一般词尾加er。(lng-lnger, tall-taller)词尾若有哑音e, 直接加r就可以。(nice-nicer)重读闭音结（尾）、单辅音字母要双写。(ht-htter, big-bigger, thin-thinner)辅音字母若加y, 记得要y变i。(happy-happier, funny-funnier) 多音节更容易，词前加mre 更好记。(utging- mre utging)
比较级（形容词/副词）的构成口诀
写出下列词的比较级形式。 large _________    8. friendly_________2. clever _________    9. many _______3.lazy ________    10. careful_________4. few __________    11. ht _______5. dirty ________    12. far _______6. wet ________    13. interesting _______7.ludly________ 14.well________
