c)以辅音字母+y结尾的,先把y改为i再加上er,est：
(2)两个音节或两个以上的音节的,在原级前加more / most.



3、形容词和副词的原级、比较级和最高级的用法：
(1)讲述某人/物自身的情况时,用原级。基本句型是：

☆表示第一个人比不上第二个人时,使用句型：
主语(第一个人物) + 谓语动词(否定式) + as / so + 形容词/副词原级 + as + 第二个人物+….
如：He is not so / as excited as his younger sister.(他没他妹妹那么兴奋) / Lily did not ride her bike so / as slowly as an old lady. (莉莉骑车不像老太太那样慢) / They didn't pick so / as many apples as the farmers (did). (他们摘的苹果不如农民多)

如：A modern train is much faster than a car.(现代的火车比轿车快多了) / This book didn't cost me more than that one.(这本书花费我的钱不比那本多)
讲述两者有差异,第一个人物不及第二个人物时,用比较级。句型是：
