(2)以字母c结尾的单音节形容词或副词直接加-st; large-largest: nice- nicest. (3)以“辅音字母+y结尾的双音节形容词或副词,先改“y”为”,再加-est:busy- busiest; early-earliest. (4)形容词或副词是重读闭音节,且词尾只有一个辅音字母时,先双写该辅音字母,再加-est:hot- hottest;:big- biggest. (5)多音节形容词或副词前面直接加most： delicious--most delicious, beautiful-most beautiful. 2.不规则变化: good (well)-best; bad (badly)-worst 三、形容词、副词的最高级形式的句子公式 1.主语+am/is/are+the+形容词最高级+比较范围(of+人/物,n+地方) (1)I am the tallest in the class.

(2) He studies best of us. 四、注意事项: 1.最高级可被序数词或much, by far,, nearly,, almost,,by no means,. not quite,, not really,, nothing like(rather不能修饰最高级)等词语所修饰。 (1)This hat is by far/much/nearly/almost/not really/by no means/not quite/nothing like the biggest. (2)How much did the second most expensive hat cost? 2.表示“最高程度”的形容词,如 excellent,. extreme,, perfect等,没有最高级,也不能用比较级。 3形容词最高级修饰作表语或宾语的名词、代词时,被修饰的词往往省略。 He is the tallest(boy)in his class. 4.作状语的副词最高级前可以省略定冠词。 Of all the boys he came(the)earliest. 5.形容词最高级前通常要加定冠词the,而以下几种情况一般不需要加定冠词he (1)形容词最高级前有序数词、物主代词、指示代词或名词所有格等限定词修饰时,最高级前不用加the.
