The half moon climbed up, Ilala, climbed up, and shone on my girl s dresser

There is a mantra for the first half of the first quarter of the first half of the month and the first half of the night for the western half of the day.

The second half of the second quarter of the second half of the month is the eastern half of the day

About the change in the phases of the moon.

Since the moon itself does not emit light, the half of the sphere facing the sun is a bright area, and the other half of the sphere is a dark area. As the position of the Moon changes relative to the Earth and the Sun, the illuminated side of the Moon is sometimes facing the Earth and sometimes facing away from the Earth; Sometimes the part of the moon facing the Earth is larger, sometimes it is smaller, so that different phases of the moon appear.

Whenever the moon runs between the sun and the earth, and the hemisphere illuminated by the sun is facing away from the earth, people cannot see the moon on the earth, and this day is called "new moon", also called "new day", which is the first day of the lunar calendar.

After the new moon, the moon follows the direction of the earth's rotation, and the bright area gradually turns to the earth, and the moon can be seen on the earth showing a trace of slender silver hooks, appearing in the western sky, bowing its back towards the sunset, this moon phase is called "moth eyebrow moon", which is the beginning of the lunar calendar.

Three, four. Subsequently, the moon moves away from the sun in the sky day by day, at the beginning of the lunar calendar.

On July and August, half of the bright area facing the Earth, one can see the half moon (convex facing west), and this phase of the moon is called the "first quarter moon".

When the Moon moves in the direction of the Earth's back sun, the lunar calendar.

Ten. Fifth, sixteenth, and seventeenth, the bright areas of the moon are all facing the earth, and we can see a full moon, and this moon phase is called "full moon", also called "hope".

After the full moon, the west side of the bright area begins to deficit, and it is the lunar calendar.

Two. On the twelfth and twenty-third, you can see the half moon (convex facing east), and this phase of the moon is called the "last quarter moon". During this period, the Moon moves closer to the Sun and rises in the east in the middle of the night.

After another four or five days, the moon turns into a moth-shaped crescent clump bud, arched back towards the rising sun, and this moon phase is called the "waning moon".

When the Moon moves between the Sun and the Earth again, the Moon returns to the "New Moon".

This is how the phases of the moon change over and over again. If we use the cycle of moon phase change (that is, the whole process of a moon phase change) to calculate, from the new moon to the next new moon, or from the full moon to the next full moon, it is a "synodic month", with a time interval of about a few days, and the length of a month in the Chinese lunar calendar is determined according to the "synodic month".

B I think so.

e I was passing by to get soy sauce.

There are only two cases of a Half Moon, one is the first quarter and the other is the last quarter. The first quarter moon is visible from the western half moon, which rises at noon and sets in the middle of the night; The last quarter moon is visible from the eastern half moon, which rises at midnight and sets at noon. Personally, I don't think it's quite suitable.

What girl can be too lazy to get up until noon? So A is definitely not right. I can barely choose B.

But getting up in the middle of the night is too hardworking, right?

The first quarter of the first quarter moon comes out of the west in the middle of the night;

The second quarter of the moon comes out of the east in the middle of the night.

I don't know.

Is it according to the direction of the dresser?

Detective questions ......

In the Northern Hemisphere, the first quarter moon faces west and is shaped like ), which occurs in the first half of the night with the moon facing east. The last quarter moon, shaped like ( appears in the second half of the night, with the moon facing west. The Southern Hemisphere is the opposite of the Northern Hemisphere. Our country is located in the northern hemisphere.

The Earth can theoretically observe the time of the Upper Xuanyue from 12 o'clock to 24 o'clock, that is to say, the upper Xuanyue rises at 12 o'clock and sets at 24 o'clock, while the Earth can actually observe the time of the lunar phase from 18 o'clock to 24 o'clock (the moon can only be seen when it is dark), that is to say, the upper Xuanyue we see has risen to mid-air, and it has begun to set when we see it.

The Earth can theoretically observe the time of the lower moon from 0:00 to 12:00, that is, the lower moon rises in the middle of the night and sets the horizon at noon, while the Earth can actually observe the moon phase from 0:00 to 6:00, and it slowly rises in the time we can observe.

Last quarter moon. The Half Moon is about the eighth or twenty-third day of the first month, and the moon is on the eighth day of the first month.

By the time it gets dark, it's already at its highest, and it's a half-moon slowly setting.

However, Luo Bing Wang's song is definitely not so earthy, that person should be called Wang Luobin.
