1、形容词表示某一事物或人的特征，副词表示某一动作的特征。
形容词和副词有三种形式：原形、比较级、最高级。比较级：+er 最高级：the +est
两个重要特征：asas中间一定用原形，than的前面一定要+er。
2、形容词、副词比较级的规则变化如下：
(1)一般直接+er。如：tall - taller, fast - faster 单音节词如果以-e结尾，只加-r。如：late - later
(2)重读闭音节词如末尾只有一个辅音字母，须双写这个字母，再加-er。如：big - bigger, fat - fatter
(3)以辅音字母加-y结尾的词，变y为i，再加-er。如：heavy - heavier, early - earlier
(4)双音节和多音节词的比较级应在原级前加more构成。如：beautiful - more beautiful, careful - more careful, quietly - more quietly, interesting - more interesting
(5)有些不规则变化的，须逐一加以记忆。如：good/well better, bad/ill worse, many/much more, far farther/further, old older/elder
练一练：
1、写出下列形容词、副词的比较级。
big good long tall old
short thin heavy young fat
light strong high far low
early late well fast slow
2、用括号内所给单词的适当形式填空。
1) I can swim as _______ (fast) as the fish, I think.
