要是以e来结尾,只有小二(r)跟上去;
重读闭音节词要牢记,双写千万别忘记;
要是“辅音+y”来结尾,小艾(i)要把y来替,再加-er两兄弟;
多音节词加上m-o-r-e,你看这样多容易。Chant(口诀)最高级规则变化口诀最高级,很容易,一般词尾加est。
(cheap-the cheapest)
词尾若有哑音e, 直接就加st。
(close-the closest)
重读闭音节, 单辅音字母要双写。
(big-the biggest)
辅音字母若加y, 记得把y变为i。
(friendly-the friendliest)
多音节,考考你,the most到底加哪里?
(popular-the most popular)3) 形容词、副词等级的用法
