earthlight

They would speak of earthlight just as we speak of moon light.

说这是光，就像我说是月光一样。

If there were any inhabitants of the moon, they would see our earth reflecting the light of the sun, again like a huge mirror hung in the sky. They would speak of earthlight just as we speak of moonlight.

假如月亮上有居民，也看到我反射阳光的同样就像一个巨大的镜子悬在空中，也像我谈月光那样谈光。
