Vocabulary:

Lunar Revolution(月球公转)- The moon's movement around the Earth.

Luna revolution length(月球公转长度)- The moon around the Earth take 27days

Phases of the moon(月的渐变)- The moon shapes change  during the revolution

Total Lunar Eclipse(全月蚀)- When the sun, earth and moon become exactly line, the moon complete dark.

Summary:

Lunar revolution is the moon around Earth. It take 27days this is called Lunar revolution length. The phase of the moon is we saw the bright parts of the moon, it can be 2 part. The waxing and waning, waxing is the moon take sunlight increase. The waning is started the moon take sunlight decrease. Their are the opposite way. The moon take this process every month.
