This is how it is --

是这样的——

	One turns away

    and walks out into the evening.

    一个人转身离开

    There is a white horse on the prairie, or a river.

    走出去进入黄昏。

    that slips away among dark rocks.

    有一匹白马在大草原上，或一条河

    在黑暗的岩石间悄然流逝。

    One speaks, or is about to speak,

    not that it matters.

    一个人说话，或者正要说，

    这并不重要。

    What matters is this --

    重要的是——

It is evening.

I have been away a long time.

现在是晚上。

Something is singing in the grass.

我离开已经有段长长的时间。

某件事物正在草地上歌唱。
