1, moon means "moon", and "moon" goes around the earth. Because the moon is the only known natural satellite on the earth, it is often used with the definite article The, and its initial letter is lowercase. In scientific articles, the first letter of the moon is often capitalized in order to stand out. The moon can sometimes be used as a metaphor, which means "the moon".
2.moon can be used with indefinite articles when it indicates a certain state, such as the moon appearing at a certain time. At this time, adjectives often come first, and the solution is often singular.
When moon is extended to "moonlight", it should be used with the definite article the or little.
The characteristics of the moon:
There are a large number of huge impact craters on the front of the moon, which are filled with basalt lava flows from dark volcanoes, forming a vast plain called "Moon Sea". In fact, there is not a drop of water in the Moon Sea. There are bright and ancient plagioclase highlands and obvious impact craters between the periphery of the Moon Sea and the Moon Sea. It is the brightest object in the sky except the sun, although it is very bright.
But its surface is actually very black, and its reflectivity is only slightly higher than that of old asphalt. Because the moon is very conspicuous in the sky, coupled with the regular changes in the phases of the moon, it has had a great influence on human culture such as myths and legends, religious beliefs, philosophical thoughts, calendar compilation, literature and art, customs and traditions.
