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

他这地球光，就像我光一样。

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.

假如亮上有居民，他看到我反射太阳光的地球同样就像一个巨大的镜子悬在空中，他像我谈论光那样谈论地球光。
