形容词比较级和副词比较级的变化规则
1. 单音节以及少数双音节形容词或副词大致按以下规律变化:
(1) 一般在形容词或副词后面直接加–er 变为比较级,加–est 变为最高级。如: old—older—oldest high—higher—highest ( short; tall; cheap; hihg; smar; young; thick, etc.)
(2) 以重读闭音节结尾,且末尾只有一个辅音字母的,则双写最后一个辅音字母,再加-er变为比较级,加 –est 变为最高级。如:
big—bigger—biggest thin—thinner—thinnest fat---fatter---fattest hot--- hotter---hottest
(3) 以“辅音字母+y”结尾的单词,则将改y为 i 再加-er变为比较级,加 –est 变为最高级。如:
busy—busier—busiest heavy—heavier—heaviest ( early, dirty; lazy; happy; ugly, etc.)
(4) 以字母 e 结尾的单词,直接加 –r 变为比较级,加 –st 变为最高级。如: large—larger—largest free—freer—freest (fine; cute; late; wise; safe; wide; large, etc.)
2. 多音节以及某些双音节形容词或副词
变比较级或最高级时,通常在其前加more变为比较级,加 most变为最高级。 如:
important—more important—most important difficult—more difficult—most difficult useful—more useful—most useful
( interesting;exciting; important; difficult; famous; delicious; serious; beautiful; careful, etc.)
3. 有些单词的比较级或最高级有两种形式,如: clever—cleverer / more clever—cleverest / most clever able—abler / more able—ablest / most able
narrow—narrower / more narrow—narrowest / most narrow
4. 有些词是不规则变化
many/much----more----most; ill/bad/badly---worse----worst; good/well---better---beat far—farther/further---farthest/furthest little -----less----least
