比较级和最高级:形容词和副词有三个等级——原级、比较级和最高级。比较级用于两者之间的比较,最高级用于三者或三者以上的比较。
比较级:表示'更...',用于两者比较
最高级:表示'最...',用于三者或三者以上比较
形容词/副词比较级变化规则:
1. 单音节词:加-er/-est(tall-taller-tallest)
2. 以e结尾:加-r/-st(nice-nicer-nicest)
3. 辅音+y结尾:变y为i加-er/-est(easy-easier-easiest)
4. 重读闭音节:双写+er/-est(big-bigger-biggest)
5. 多音节词:前面加more/most(beautiful-more beautiful-most beautiful)
不规则变化:good/well-better-best, bad/badly-worse-worst, many/much-more-most, little-less-least
比较级用法:A + be动词 + 比较级 + than + B
最高级用法:A + be动词 + the + 最高级 + (in/of...)
as...as:表示'和...一样...'(原级)
not as/so...as:表示'不如...'(原级)

最高级前通常要加the(副词最高级前可省略the)
