Ww want to know what we can to help you.

题目

Ww want to know what we can to help you.
Ww want to know what we can to help you.
Ww want to know what we can do to help you.
这两句话那个对啊?
Ww want to do what we can to help you.这句话对吗?

答案

We want to know what we can do to help you
这句话是对的.因为can是情态动词,后面要加动词原形.即can+V原.
你再结合翻译：
我们想知道我们能“做”些什么来帮助你.“做”就是“do”了.what是do的宾语.如果不用do,那么what就用的没有意义了
综上可知正确答案
