英语形容词比较级
一)一般句式的构成: A + is / are+ 形容词比较级+ than + B A 是主格 B 是宾格如: She is taller than me. 主格 形容词比较级 宾格

二、英语形容词比较级的构成英语形容词比较等级有三个: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 clean cleaner cleanest 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,须先双写这个辅音字母,再加-er(比较 级),-est(最高级)【例】 big bigger biggest hot hotter hottest red redder reddest 4)少数以-y,-er,ow,-ble结尾的双音节词,末尾加-er(比较级),-est(最高级)。 以-y结尾的词,如-y前是辅音字母,则变y为-i,再加-er和-est。以-e结尾的词只加-r和-st。 【例】 clever cleverer cleverest narrow narrower narrowest able abler ablest easy easier easiest 5)其它双音节和多音节词皆在前面加单词more和most。【例】 careful more careful most careful difficult more difficult most difficult delicious more delicious most delicious

不规则变化
原级 比较级 good/well better bad worse many/much more little less far farther/further 最高级 best worst most least farthest/furthest

注:有些形容词一般没有比较等级。如: right, wrong, woolen等。形容词的比较等级的用法: 比较级用于二者的比较。【例】 Li Ping is older than Wang Hai. 李平比王海年纪大。 There are more students in Class One than in Class Two.一班比二班学生多。
