距离程度。副词比较级和最高级的形式。
副词和形容词一样，也有它的比较级和最高级形式。 可以参考形容词的变换形式。
单音节副词的比较级是在副词后面加上 -er 构成的，最高级是在副词后面加上 -est 构成的。
near nearer nearest
hard harder hardest
多音节副词的比较级是在副词的前面加上 -more 构成的。 最高级是在副词前面加上 -most 构成的。
warmly more warmly most warmly
successfully more successfully most successfully
副词的比较级和最高级用法同形容词的比较级用法基本一样。 最高级形式句中 the 可以省略。副词比较级和最高级的变化形式与形容词基本上一样。
一般副词。hard→harder →hardest
fast→faster →fastest
late→later →latest
early→earlier →earliest
特殊副词。well →better →best
much →more →most
badly →worse →worst
little →less →least
far-farther(further)-farthest(furthest)
但是，开放类副词即以后缀 ly结尾的副词不能像形容词那样加 er或 est，如。
quickly →more quickly →most quickly
quietly →more quietly →most quietly
注］： early中的 ly不是后缀，故可以把 y变 i再加 er和 est
