形容词、副词的比较级的构成：
规则变化: 单音节和少数双音节形容词、副词比较级的构成。 1) 在词尾加-er
tall — taller smart—smarter
short — shorter fast —faster
2) 以不发音的字母e 结尾的，加-r
nice — nicer large — larger fine — finer late — later
3) 重读闭音节结尾且末尾只有一个辅音字母的，先双写该辅音字母，再加-er。
big — bigger fat — fatter
thin — thinner hot — hotter
wet— wetter
4) 以辅音字母+y结尾的词，先变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
beautiful — more beautiful
comfortably — more comfortably
quickly — more quickly
不规则变化：
good / well– better
bad / badly– worse
many / much - more
little - less
far - farther / further
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。
