I'm much more careful than you.(为什么要用much more careful )

问题描述:

I'm much more careful than you.(为什么要用much more careful )

careful多音节,比较级用more+形容词,much修饰比较级,表示认真很多

我比你仔细的多。
形容词前用much,就是“...的多”的意思,但是careful不是单音节词,所以careful前面用more
举例:高的多much longer(单音节词)
仔细的多 much more careful(不是单音节词)

much修饰more careful,表程度 更仔细
