原级
比较级

以不发音的e结尾 nice(好的)
nicer nicest的单音词和少数
large(大的) larger largest 2.以- le结尾的双 able（有能力的) abler ablest音节词只加-r,-st

most important来构成比较级和 easily(容易地) 最高级。
more easily
most easily
比较级的句子结构通常是：
什么 + 动词be (am , is , are ) + 形容词比较级 + than（比）+ 什么 ,如：
I’m taller and heavier than you.（我比你更高和更重。）
An elephant is bigger than a tiger.（一只大象比一只老虎更大。）
☆注意
比较的两者应该是互相对应的可比较的东西。
典型错误：My hair is longer than you.（我的头发比你更长。）
比较的两者是我的头发、你（整个人），那么比较的对象就没有可比性。
应该改为：My hair is longer than yours.或My hair is longer than your hair.
