(例外：shy(害羞的)—shyer—shyest)(3) 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加词尾-er和-est构成比较级和最高级：big—bigger—biggest。

多音节和部分双音节词通过在其前加more和most构成比较级和最高级：原级比较级最高级difficult(困难的) more difficult most difficultdangerous(危险的) more dangerous most dangerousbravely(勇敢地) more bravely most bravely注：(1) 有的双音节词(如clever, common, gentle, handsome, happy, narrow, polite, quiet, shallow, simple, stupid，often, seldom)可以有两种方式构成比较级和最高级级：clever—cleverer / more clever —cleverest / most cleveroften—more often / oftener—most often / oftenest。
