1、单词末尾加“er”
2、以e结尾的单词末尾加“r”
3、双写闭音节词的末尾字母,再加“er” 双写闭音节词也称为重音节词
4、以辅音字母“y”结尾的词,变“y”为“i”,再加“er”
5、在多音节词的前面加“more”,这种后面不用加“er”。
6、不规则的形容词变化,如: 原形,比较级 good/well,better bad,worse many/uch,more little,less far,farther/further 没有比较级的形容词有:right, wrong, woolen等。 至于说判断一个形容词究竟是哪类的,这就得靠你将来的累积经验了,一般小学主要学规则的! 注:‘/’表示“或者” 三者或三者以上相比,表示最高程度时,用“ the十最高级”的结构表示.这种句式一般常有表示比较范围的介词短语.例如: Zhang Hua is the tallest of the three. He works (the) hardest in his class.
②最高级可被序数词以及 much,by far,nearly,almost,by no means,not quite,not really,nothing like等词语所修饰. 例如: This hat is by far/much/nearly/almost/not nearly/by no means/not quite/nothing like the biggest. How much did the second most expensive hat coat?
③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.
④形容词最高级修饰作表语或介词宾语的名词、代词时,被修饰的词往往省略. He is the tallest(boy) in his class.
⑤作状语的副词最高级前可以不加定冠词.例如 0f all the boys he came(the) earliest.
