readers are much more interested in reading the stories.much more是什么意思

首先.more interested 是比较级.而much又是修饰比较级.是个程度副词.修饰比较级的还有a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even .
再一例 He is much taller that me.

much用来修饰more，本来是readers are more interested in reading the stories.意思是读者更感兴趣于阅读故事，加上much，就增强了语气

读者更感兴趣于阅读故事。
much more是更加的意思

更加，进一步 可以当作adv（副词）来用
