The food she has prepared for the party is not enough,for th

两者可指“更多”.
many more后接一个名词一定是个复数可数名词.若不接名词,则more本身就被看作是一个复数名词,表示复数概念.如：
Some students are against the plan,but many more support it.一些同学反对这项计划,但是有更多人支持它.
much more后接一个名词,这个名词一定是个不可数名词.若不接名词,则more本身就被看作是一个不可数名词.如：
The farmers have produced much more rice.这些农夫收了更多的稻谷.
many more不可能修饰形容词和副词,而much more和far more,even more,still more 等一样,可以修饰形容词和副词,表示“更加”.如：
This TV set is much more expensive.这台电视机要贵得多.
