形容词与副词比较等级的构成方法
 
1. 单音节和部分双音节形容词或副词通常加后缀–er和–est构成比较级和最高级。此时,还需注意:若原级以字母e结尾,则只加-r和-st;若原级以“辅音字母+y”结尾,则应将y改为i,再加-er和-est构成比较级和最高级;若原级为重读闭音节结尾,且末尾只有一个辅音字母,则双写这个辅音字母后再加词尾-er和-est构成比较级和最高级。如:
long→longer→longest large→larger→largest
busy→busier→busiest big→bigger→biggest
2. 多音节和部分双音节形容词在其前加more和most构成比较级和最高级。如:
useful→more useful→most useful
difficult→more difficult→most difficult
常见的不规则形容词与副词的比较等级变化:good→better→best;well→better→best;bad→worse→worst;badly→worse→worst;ill→worse→worst;much→more→most;many→more→most;little→less→least;far→farther / further→farthest / furthest;等。
注:less和least也用来构成比较级或最高级,表示“较不…”和“最不…”:careful→less careful→least careful。
