A crescent moon peeped out from behind the clouds.

一弯新从云中出现。

The moon was a brightly shining crescent.

那晚亮是一弯闪闪发亮新。

Cradled in the sunlit lunar crescent, the night side of the Moon is faintly illuminated by earthshine -- sunlight reflected from planet Earth.

球夜晚面位于太阳光照亮面上方，其也被地球反照光（地球反射太阳光）照亮。
