不要变y为i加er,另外还要看几个音节,2个以上的用more构成。
辅音字母加Y,去Y变i加er;元音字母加Y,直接加et。
因为关于y的规则就是以辅音字母加y结尾的形容词和副词,变y为i,再加er,est,形容词变副词也如此。
同级比较:
由“...as + 形容词原型 + as...”或“...as + 形容词 + 名词 + as...”构成。My grandpa is as energetic as a young man.Exercise is as useful a way as any other to lose unwanted weight.I try to find as much information as I can about what happened。
由“...not so (as) + 形容词或副词原型 + as...”或“...not so (as) + 形容词 + 名词 + as...”构成。Luckily, the weather is not so wet as it is today。
