小学英语形容词和副词比较级和高级构成规则

来源:趣趣ABC少儿英语 时间:2019-05-29 17:58:51

   小编对小学英语形容词和副词比较级和高级构成规则进行了总结,希望能够帮助大家。

   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,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,高级在原级后加-st;

  如:large→larger→largest nice→nicer→nice stable→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,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,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,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)形容词高级前通常必须用定冠词the,副词高级前可不用。

  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
