(比较级)

(最高级)2)以-e结尾的单音节形容词的比较级和最高级是在词尾加-r和-st构成。wide(原级)

(比较级)

(最高级)3)少数以-y,-er,-ow,-ble结尾的双音节形容词的比较级和最高级是在词尾加-er和-est构成。clever(原级)

(比较级)

(最高级)4)以-y结尾,但-y前是辅音字母的形容词的比较级和最高级是把-y去掉,加上-ier和-est构成.happy(原形)

(比较级)

(最高级)5)以一个辅音字母结尾其前面的元音字母发短元音的形容词的比较级和最高级是双写该辅音字母然后再加-er和-est。big(原级)

(比较级)

(最高级)6)双音节和多音节形容词的比较级和最高级需用more和most加在形容词前面来构成。beautiful(原级)?

(比较级)

(比较级)difficult(原级)

(最高级)常用的不规则变化的形容词的比较级和最高级:原级比较级最高级goodbetterbest

manymoremostmuchmoremostbadworseworstfarfarther,furtherfarthest,furthest形容词前如加less和least则表示"较不"和"最不"important重要lessimportant较不重要leastimportant最不重要形容词比较级的用法:形容词的比较级用于两个人或事物的比较,其结构形式如下:主语+谓语(系动词)+形容词比较级+than+对比成分。也就是,含有形容词比较级的主句+than+从句。注意从句常常省去意义上和主句相同的部分,而只剩下对比的成分。Ourteacheris
