形容词、副词的比较级变化:

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-ertall—tallersmart—smartershort—shorterhigh—higherfast—fasterwide—wider形容词、副词的比较级构成GRAMMAR2)以不发音的字母e结尾的，加-r

nice—nicerlarge—larger

fine—finerlate—later

wide—wider3)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—biggerfat—fatterthin—thinnerhot—hotterwet—wetter4)以辅音字母+y结尾的双音节词，先改y为i，再加-er。

happy—happierearly—earlierfunny—funniereasy—easier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)形容词、副词比较级的不规则变化：
