小升初网整理了2018年小升初英语词汇整理，仅供参考。
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… 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
