how about going dancing还是how about go dancing

how about going dancing当然是这个

别让两个ing给弄迷糊了。

第一个ing是how about后接动词ing形式决定的，第二个ing是go doing sth决定的，一码是一码，不矛盾。

前面几个说的都对。

How about doing sth./go doing sth. 推出了 How about doing sth.

How about /What about diong sth 是固定结构

go doing sth 如go swimming, go shopping, go fishing 等也是固定结构。

两个结构套在一块就是how about going dancing?

所以 上面的老兄说的对。
