nice- nicer, large- larger以辅音加y结尾,改y为i, -er
happy-happier辅音字母结尾的重读闭音节词，
双写末尾的辅音字母，-er
thin- thinner多音节词， 和部分双音节词，
在词的前面加more

tall — taller smart—smarter
short — shorter high — higher
Summary2) 以不发音的字母e 结尾的，加-r; nice — nicer large — larger fine — finer late — laterSummary3)重读闭音节以一个辅音字母结尾的，先双写辅音字母，再加-er； big — bigger fat — fatter
thin — thinner red — redder
hot — hotter wet— wetter
4以辅音字母+y结尾的双音节词，先改y为i，再加er ；
happy—happier early— earlier
funny—funnier easy — easier 5)多音节词和部分双音节词要在前面加more；
important—more important
delicious —more delicious
expensive —more expensive
athletic —more athletic
outgoing —more outgoing
tired — more tired
serious —more serious比较级有规律,词尾加上-er两兄弟;
要是以e来结尾,只有小二(r)跟上去;
重读闭音节词要牢记,双写千万别忘记;
要是“辅音+y”来结尾,小艾(i)要把y来替,
再加-er两兄弟;
多音节词加上m-o-r-e,你看这样多容易. Chant(口诀)tall
