绝大多数形容词有三种形式,原级,比较级和最高级, 以表示形容词说明的性质在程度上的不同。
形容词的原级: 形容词的原级形式就是词典中出现的形容词的原形。 例如: poor tall great glad bad
形容词的比较级和最高级: 形容词的比较级和最高级形式是在形容词的原级形式的基础上变化的。分为规则变化和不规则变化。
规则变化如下:
1) 单音节形容词的比较级和最高级形式是在词尾加 -er 和 -est 构成。
great (原级) (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) (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
good------better------best
many------more------most
much------more------most
bad------worse------worst
far------farther, further------farthest, furthest
形容词前如加 less 和 least 则表示"较不"和"最不
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。
形容词最高级的用法:
形容词最高级用于两个以上的人和物进行比较, 其结构形式为:
主语+谓语(系动词)+the+形容词最高级+名词+表示范围的短语或从句
形容词、副词比较级和最高级
Comparative degree & Superlative degree:
一、比较级构成方式:
A.adj / adv + er / est
poor→poorer→poorest fast→faster→fastest
B.词尾e + r / st
large→larger→largest fine→finer→finest
C.重读闭音节中短元音 + 辅音词尾→双写辅音词尾 + er / est.
big→bigger→biggest hot→hotter→hottest
D.辅音 + y→i + er / est

(1)笔记要点:两个相比较的主语必须相对应。

... The climate of Shanghai is hotter than that of Beijing.
... My Schoolbag is larger than hers.
... The book is much more interesting than that one.
(2)笔记要点:两个形容词比较级由 and连在一起,表示“越来越……”

... She is becoming more and more beautiful
.

... The older we grow, the poorer our memory will be.
... The earlier we start, the sooner we'll get there.
(4)笔记要点:二者之比较。而Of the three girls, she is the cleverest.
... I prefer the cheaper one of the two books.
... Of the two brothers, he is the cleverer.
最高级构成方式:
三者或三者以上进行比较,“the + 形容词 / 副词est”。
(1)
