eg :young--younger—the youngest
bright--brighter---the brightest 明亮 /聪明的
high--higher--the highest

eg: busy--busier--the busiest
Eg: China is bigger than US. I am shorter than you. Now ,I feel better than before.
1. 最高级用于三者以上比较，形容词的结构形式是“ 定冠词＋形容词最高级＋名词＋表示范围的短语或从 句”(如all, of all, of the tree, in the world, that has ever taken place等)
②词末为--e（不发音）+ r --+st eg:fine--finer--the finest nice--nicer--the nicest close--closer--the closest large--larger--the largest
③重读闭音节，末尾只有一个辅音字母的： 双写辅音字母+er--双写辅音字母+est eg:hot--hotter--the hottest
