more 最 高级则是在词前面加 most 举例来说 old smart strong weak high low 等等都是单音节的 形容词 它们的变化如下 原级 比较级 最高级 old older oldest smart smarter smartest strong stronger strongest weak weaker weakest high higher highest low lower lowest 以上的形容词 都是单音节的 以下的例子都是双音节的形容词 原级 比较级 最高级 difficult more difficult most difficult delicious more delicious most delicious beautiful more beautiful most beautiful correct more correct most

nicer nicest wise wiser wisest 2 形容词的词尾是 y 而前一个字母是一个子音 则去掉 y 加上 ier 或 iest 原级 比较级 最高级 lucky luckier luckiest happy happier happiest pretty prettier prettiest dry drier driest easy easier easiest 3
