为什么用with不能用has

it's a green monster with six ears and three eyes为什么用with不能用has
has 是动词,这句话是个简单句,简单句只能有一个谓语,也就是只能有一个动词,就是这里的is,所以has不能用

如果用has的话,这一句话就有两个谓语啦,一个是is 还有个就是has了.
除非用定语从句
It's green monster which has six ears and three eyes.

用with或that having

it's a green monster with six ears and three eyes.
要用has 就要改成
it's a green monster who has six ears and three eyes.
