已经快过去一年了。

It's been almost a year.

可我们对他们还是一无所知。

yet we still know nothing about them.

我们是谁？

Who they are,

从哪里来？

where they come from.

为什么到这里来。

why they went down...

我们只知道，自从他们来之后。

all we know is, since they came.

我们每天只能有两个小时的和平时间。

two quiet hours a day is all we have.

什么声音？

What was that?

我也不确定。

I'm not sure.

是枪声吗？

A gunshot?

不可能。

No, it can't be.

不，我听见发动机的声音。

No,I heard an engine.
