一、形容词的比较级

　　1、形容词比较级在句子中的运用：两个事物或人的比较用比较级，比较级后面一般带有单词than。比较级前面可以用more, a little 来修饰表示程度。than后的人称代词用主格（口语中可用宾格）。

　　2．形容词加er的规则：

　　⑴一般在词尾加er ；

　　⑵以字母e 结尾，加r ；

　　⑶以一个元音字母和一个辅音字母结尾，应双写末尾的辅音字母，再加er ；

　　⑷以“辅音字母+y”结尾，先把y变i，再加er 。

　　3．不规则形容词比较级：

　　good-better, beautiful-more beautiful

　　二、副词的比较级

　　1．形容词与副词的区别 (有be用形，有形用be；有动用副，有副用动)

　　⑴在句子中形容词一般处于名词之前或be动词之后

　　⑵副词在句子中最常见的是处于实义动词之后

　　2．副词比较级的变化规则基本与形容词比较级相同 (不规则变化：well-better, far-farther)
