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

他会说这是光，就像我说是光一样。

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，他也会看到我反射太阳光的样就像一个巨大的镜子悬在空中，他也会像我谈论光那样谈论光。
