见过蠢的没见过这么蠢的英文

I have never seen a foolish person like you

I have seen some fools but no one can be more stupid then this.....

I have never seen the one more foolish

否定+more 表示 没有...更....的了
的意思
呵呵，加油哦

是指人吗？“这么蠢的”是已经见到了吗？
如果是眼前的，见到了的是：
I've seen stupid people but I had never seen such an idiot before.
如果是听说还没见到是：
I've seen stupid people but I have never seen such an idiot before.

如果指的“这么蠢的”是复数的话 idiot后面要加s， 变成 "... such idiots before".

have seen some fools but no one can be more stupid then this.....
