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

他们会说这是地球光，就像我们说是月光一样。

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，他们也会看到我们反射太阳光的地球同样就像一个巨大的镜子悬在空中，他们也会像我们谈论月光那样谈论地球光。
