高中英语比较级的构成规则
高中英语比较级是重点内容之一,变化较多。小编整理了一份高中英语比较级的构成规则,供大家在学习时参考。
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,比较级在原级后加-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,把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(well)→better→best
bad(ill)→worse→worst
old→older/elder→oldest/eldest
many/much→more→most
little→less→least
far →further/farther→ furthest/farthest
