有没有many more?

有没有many more 有的话告诉我用法

有的。

many more和much more 都可指“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。
We have many more left. 我们还剩下很多。
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。
She has much more to do. 她还有很多事要去做。

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。
He worked much more carefully on the new design. 在这项新的设计上，他工作努力得多了。

有啊，many more修饰可数名词的单数

There are many more blind people.

有many more这种形式,初中英语书上册在第九模块Does the tiger eat meat?一课中出现过.里面有句话大概是这样的:There are 5,000 animals in the zoo.Zebra,polar bear, tiger and many more. many more 与much more的意思是一样的,只是,many more是就可数名词而言的,而much more是就不可数名词而言的.

没有many more，只有much more

没有，much才能修饰比较级，many不行，所以有much more ，没有many more
