There's no comparison between them,one being clearly much better than the other为啥是being?

There's no comparison between them,one being clearly much better than the other为啥是being?

这个句子是非谓语哦·
分解成俩个句子就是：
There's no comparison between them 他们俩个没有可比性
One is clearly much better than the other 一个明显优于另外一个.
俩个句子放在一起,又没有连接词,只能用非谓语了····being后边是个独立主格结构,在句中作状语,主语不是个句子

后面的one being clearly much better than the other作补充原因。前面的There's no comparison between them结构已经完整，所以后面那句没有助词is/are，只能用being
