翻译：我们到底缺少了什么？

What on earth we are lacking for?
How long it will take from my place to your place?
What else we haven't finished?
Note:
on earth (到底)

What do we really need?
How long does it take from my place to yours?
What else left for us to do?

我们到底缺少了什么？What are we lacking of (in) ? (short of)

还有：从我这里到你那里要走多久？How long we have to walk to reach your place from here (from my place) ?

我们还剩哪些东西没做完？How we left behind anything undone ?
