形容词和副词比较级的变化规则

1.一般单音节词和少数以-er-ow结尾的双音节词,比较级在后面加-er,最高级在后面加-est

1)单音节词

如:small→smaller→smallest short→shorter→shortest tall→taller→tallest great→greater→greatest 2)双音节词

如:clever→cleverer→cleverest narrow→narrower→narrowest 2.以不发音e结尾的单音节词,比较在原级后加-r,最高级在原级后加-st

如:large→larger→largest nice→nicer→nicest able→abler→ablest

3.在重读闭音节(即:辅音+元音+辅音)中,先双写末尾的辅音字母,比较级加-er,最高级加-est

如:big→bigger→biggest hot→hotter→hottest fat→fatter→fattest

4.以“辅音字母+y”结尾的双音节词, y改为i,比较级加-er,最高级加-est

如:easy→easier→easiest heavy→heavier→heaviest busy→busier→busiest happy→happier→happiest 5.其他双音节词和多音节词,比较级在前面加more,最高级在前面加most

如:beautiful→more beautiful→most beautiful different→more different→most different easily→more easily→most easily

注意:(1)形容词最高级前通常必须用定冠词 the,副词最高级前可不用。 例句: The Sahara is the biggest desert in the world.


2 形容词most前面没有the,不表示最高级的含义,只表示"非常" It is a most important problem. =It is a very important problem. 6.有少数形容词、副词的比较级和最高级是不规则的,必须熟记。 如:good→better→best well→better→best bad→worse→worst ill→worse→worst

old→older/elder→oldest/eldest many/much→more→most

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