小升初英语解析之形容词、副词
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：as……as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…
