用括号里单词的正确形式填空。
1. I’m twelve years old. He is eleven. I’m older ___________ than him. (old) 2. When it is hot in the morning it is to be hotter ___________ at noon. (hot) more interesting 3. His ideas are much ___________ than Jim’s. (interesting) easier 4. Exercise One is much ___________ than Exercise Two. (easy) 5. The girl is ___________ than her sister. (good) better
3)重读闭音节如末尾只有一个辅音字母，须先双写这个
辅音字母，再加-er；
big — bigger hot — hotter happy—happier fat — fatter wet— wetter early— earlier
thin — thinner red — redder
4)以辅音字母+y结尾的双音节词，先改y为i再加er ；
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。
1.tall 2.nice 3.big
taller
nicer bigger
4.funny

6)不规则变化
