结构
对于许多短形容词，加 -er。

如果形容词以 -e 结尾，只加 -r。
- nice → nicer
- large → larger
如果短形容词以一个元音 + 一个辅音结尾，末尾辅音通常要双写。
- big → bigger
- hot → hotter
如果形容词以辅音 + -y 结尾，把 y 变成 i 再加 -er。
- happy → happier

对于许多较长的形容词，使用 more。
主语 + be + more + 形容词 + than + 名词/代词
- more beautiful

要表示较低的程度，使用 less。
主语 + be + less + 形容词 + than + 名词/代词

一些常见形容词有不规则的比较级形式。
