形容词和副词的比较级和最高级的用法

【要点探究】

1.英语形容词，副词比较等级有三个：原级，比较级和最高级。

形容词比较等级形式变化有规则的和不规则的两种。

规则变化

(1)单音节词末尾加-er（比较级），-est（最高级）

【例】原级比较级最高级

great greater greatest small smaller smallest quiet quieter quietest

(2)单音节如以e结尾，只加-r（比较级），-st（最高级）

【例】fine finer finest nice nicer nicest wide wider widest

(3)闭音节单音节词如末尾只有一个辅音字母，（辅音﹢元音﹢辅音【w,r除外】）须先双写这个辅音字母，再加-er（比较级），-est（最高级）

【简记：大红辣椒潮湿瘦变胖】

big bigger biggest hot hotter hottest red redder reddest

fat fatter fattest thin thinner thinnest wet wetter wettest

（4）辅音字母加y结尾的词，则变y为-i，再加-er和-est。。

【例】easy easier easiest healthy healthier healthiest sunny sunnier sunniest

（5）其它双音节和多音节词皆在前面加单词more和most。

【例】delicious more delicious most delicious

carefully more carefully most carefully

注意：tired more tired most tired

（6）不规则变化原级比较级最高级

good/ well →better best，bad →worse worst，many/ much →more most

little →less least ，far → farther/further farthest/furthest

注：有些形容词一般没有比较等级。如：right, wrong, woolen等。

2.形容词的比较等级的用法：比较级用于二者的比较，并且用于同类事物之间的比较，不同事物之间不可以比较。最高级用于三者或三者以上比较。

（1）用于两者比较，表示“……比……更……”

②“A+谓语动词+副词比较级+than+B”
