大多数形容词具有三个等级:原级、比较级和最高级。
一、构成方式
形容词比较级一般是在原级上加er,最高级一般是在原级上加est。具体说来:
多音节和部分双音节形容词在词前加上more和most构成比较级和最高级。如:
careful—more careful—most careful
important—more important—most important
不规则变化:
good/well-better-best many/much-more-most
bad/ill-worse-worst little-less-least
far-farther-farthest far-further-furthest
old-older-oldest old-elder-eldest
二、基本用法
1. 两者比较,我们用比较级,常有“A+be+形容词比较级+than+B”或“Who/Which is+形容词比较级,A or B?”等结构。
eg:Tom is stronger than Jack.
汤姆比杰克强壮。
Which is more important, health or wealth?
健康和财富,哪一个更重要?
2. 三者或三者以上的比较,我们用最高级,常有“A+be+the+形容词最高级”这样的结构。
其中形容词最高级前通常加the。后面可用of(in)短语等来说明比较的范围。
eg:He is the tallest of the four boys.
在这四个男孩中,他的个子最高。
另外,“one of the+形容词最高级+名词的复数形式”也是最高级的常用结构,意思是“最……之一”。
eg:Beijing is one of the most beautiful cities in the world. 北京是世界上最美的城市之一。
