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more
tall -- taller
nice -- nicer
fat -- fatter

(long-longer, 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。
(hot-hotter, 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more 更好记。
