512, do you know the first and fifteenth days of junior high school?

The Earth's rotation is one day and one night, which is called the "solar day". When the earth rotates, the ground facing the sun is called "day", and the ground facing the sun is called "night". It can be seen that the earth itself is a "combination of yin and yang". The ecliptic is the great circle drawn by the sun in the sky during the year observed by the earth (the reference), and its plane is the plane of the earth's orbit around the sun, and the equator, the largest outer circle of the earth's rotation, intersects at an angle of about 23 and a half degrees, and this intersection is the difference between the vernal equinox and the autumnal equinox, which is the point where the sun passes on March 21 (solar day), and the autumnal equinox is the point where the sun passes on September 23. After the vernal equinox, that is, after March 21, the sunshine in the northern hemisphere gradually increases, so the northern hemisphere (divided by the equator) has short days and short nights, and the southern hemisphere is reversed; After the autumnal equinox, i.e. after September 23, the sunshine in the southern hemisphere increases, so the days are shorter and the nights are longer in the northern hemisphere, while the opposite is still true in the southern hemisphere.

The orbit of the moon is called the white path, and the white path and the ecliptic are the two great circles on the celestial body. With five degrees and nine minutes obliquely, the moon orbits the earth once, haunts the ecliptic twice, and the 27th day of the calendar is 7 hours, 43 minutes and 11 seconds, which is the time required for the first anniversary of the moon's revolution, which is called the "sidereal month". However, when the moon circles the earth, the position of the earth also changes due to the revolution, and the moon travels 13 degrees and 15 minutes a day, so the moon moves around the earth once a week, and it takes 29 days to 12:44:22.8, which is called the "synodic month", and the custom of the so-called January refers to the synodic month.

Because the number of days in the month cannot have odd zero, the lunar month is the 29th day of the small month or the 30th day of the big month, but there is no fixed law for the large and small months of the lunar calendar, but the leap month is generally the 29th day of the small month, and the month before the leap month is the 30th day of the big month. Each month begins with the day of the conjunction, that is, the first day of the new year. Every year, the first day of the year is close to the beginning of spring.

The earth revolves around the sun once, that is, the moon circles the earth twelve times and one-third, and the number of months in a year cannot have odd zeros, so the twelve months of a year, only three hundred and fifty-four days, compared with the reality of the year, about eleven days, the accumulation to three years, the remaining thirty-three days, so every three years must be placed a leap month, the remaining three or four days, and then two years, the remaining twenty-five days or twenty-six days, can be placed a leap month, on average, every nineteen years (11×20-11 = 209) must be placed seven leap months (about 209 days). In a month, there is usually one solar term, but the average number of days in each solar term is about 30 days and four-tenths. The lunar month is the day of the conjunction of the sun and the moon, and the second conjunction is about 29 days and a half, so the number of days of the month is either 29 or 30. The number of days in the month is actually twenty-nine and a half, so every two or three years of the calendar must meet January, and there are only those who have no air in it. That is, a leap month is a month with a festival and no air, a leap year is a leap year, a leap year has thirteen months, and a normal year has twelve months. However, it is important to note that the common and leap years of the lunar calendar are not the same as the ordinary and leap years of the solar calendar.

The moon goes around the earth, the earth to where the month also follows, the daily line of thirteen degrees is very strange, so there is a difference between profit and loss every month, the lunar calendar is a new month and a look, the beginning of the month is completely obscure, the calendar is bent on the second or third day, and then the fourth or fifth day to see its half, and then seven or eight days to see its surplus, and then gradually lack so that it is obscure, that is, the end of the lunar month.

Because the moon has no instinct to shine, the reflection of sunlight is different, when it is completely obscure, that is, the moon is between the sun and the earth, the sun and the moon are the same longitude, and the light-receiving surface of the moon cannot be reflected on the earth, which is the "new day", which is the first day of the new year. When it is more than seven days away from the sun and 90 degrees away from the sun, the sun gradually sees half of it after the moon, which is called "winding". As for the moon and the sun directly opposite each other is one hundred and eighty degrees, and the sun and moon are in the same longitude, the earth is between the sun and the moon, and the light-receiving side of the moon is completely facing the earth, so the light is round and called "looking", that is, the fifteenth day. Seven days away, 90 degrees away from the sun, the sun is in front of the moon, and only half of its face is seen, which is called "the next string". The closer it is to the sun, it is still between the sun and the earth, and the light is completely obscure, so "the intersection of the obscurity, the beginning of the obscurity is the end of the obscurity". Therefore, there are celestial phenomena such as "solar eclipse", "lunar eclipse", "total solar eclipse", "partial solar eclipse", "annular solar eclipse", and "solar eclipse" always occurs on the first day of the lunar calendar; And "lunar eclipses" always occur around the fifteenth day of the lunar calendar. If someone asks you, "Do you know the first and fifteenth days of junior high school?" You should say, "Yes!" "Who said that? You just said that I was old and single, and Shan Tianfang called it.

An astronomical phenomenon in which a "solar eclipse" occurs. It is called the New Moon. The time when the sun and the moon are in the same direction of the earth, that is, the conjunction of the sun and the moon is called the new moon, and the moon phase at this time is called the new moon. The moon's proportional New Moon. On the day of the New Moon, the Moon appears almost at the same time as the Sun. The dark hemisphere of the moon faces the daytime hemisphere of the earth, and it is difficult to see the moon because of the strong daylight. The moon is not visible at all in the Earth's night hemisphere. The day on which the new day is the first day of the lunar month (lunar calendar), if the sun, moon, and earth happen to be in a straight line or close to a straight line, and the moon obscures all or part of the sun's disc, there will be a total solar eclipse, an annular solar eclipse, or a partial solar eclipse. The so-called "solar eclipse" is a phenomenon in which the moon's light is blocked by the moon and cannot reach the celestial bodies on the earth when the moon orbits between the earth and the sun. When the sun is completely blocked by the moon, it is called a total solar eclipse, when it is partially blocked, it is called a partial solar eclipse, and when the central part is blocked, it is called an annular solar eclipse. It can be seen that the phenomenon of "solar eclipses" always occurs on the first day of the lunar calendar. Actually, this phenomenon is easy to say, but it is not too easy to happen and understand! It should be said that "it is difficult to say, and it is easy to say", it depends on everyone's "three-dimensional space" imagination and comprehension ability!

According to the above, the "three cats" saw in a dream: "Am I dreaming? No! By no means! ...... "Dreamers often say this and think so; Sober people often say that others dream of good things until they dream of marrying a daughter-in-law. However, the "three cats" are harmless but insist that he is not dreaming. But who knows, he is indeed dreaming! And it's drunk and unconscious in Miss Chen's room! Is he obsessed? Or is he masked in the drum? Or did he never wake up from a long dream? Perhaps, only he knows best in his heart that in order to pursue the truth, he has drunk and dreamed of death several times. Even in this life, in order to pursue the persistence of truth, he will face all retribution and give all his sincerity and love. May this dream, no, hope this love, reach the edge of the cape!

In this way, he and Shi Xiaomei are still immersed in the silent "telling" like falling flowers. I don't know how long it took, Shi Xiaomei seemed to feel a little tired lips, so she wanted to remove her hot and hot lips. However, he still didn't feel enjoyable, hugged her tightly, the heat spurted wildly, and his willingness rose suddenly! One after another, he rose again, sucking and rubbing fiercely at Shi Xiaomei, until she was almost breathless. However, instead of being depressed, her emotions were stimulated by his sudden sucking and squeezing! She could no longer control the rise of lust and the burning of lust, and raised her hot and intoxicated lips high. Her strength, constantly emerging, is the most charming, overcoming rigidity with softness. What is the situation in the world? Straight Christians promise life and death. Look at how many stories there are in the world, and the most ecstatic is in the lips.

The feeling of happiness is so refreshing. "Three cats" Ye Wuwu still besieged Shi Xiaomei's tongue with his lips, teeth and the tip of his tongue, and he was not willing to leave this sweet lips, teeth and tongue at all. It was as if he had forgotten everything, all his troubles and sorrows, and all his pessimism, disappointment, frustration and melancholy. In front of him, there was a face like a flower. It is "hibiscus like a willow like an eyebrow, and a face like a peach blossom is so charming." "Why don't you be sultry? However, yes, who had restrained this fire of lust for a long time, was still unbearable in the end, and finally got her wish and gnawed at each other's lips like lacquer. He had turned the silent kiss into an emotional "telling", a moment he had longed for; However, he was in control for a long, long time. Until today, he finally emerged with one wave of enthusiasm and strength, which made him uncontrollable, made him bold, and let him convey the love from the bottom of his heart to her.

The feeling of a dream is like reality. He and she were still hugging and kissing. Gradually, Shi Xiaomei's clothes flew off one by one, gradually revealing her white jade, plump and warm skin and charming jade legs...... Suddenly, the "Golden Fan Boy" Chen Jiannan came in a gust of wind, and took Shi Xiaomei away from his arms, and disappeared in an instant. At this moment, he seemed to feel that he had just woken up from a big dream, and he was sad several times, as if he had been gouged out of his heart. When he looked behind him, he saw Chen Jiannan hugging the naked Shi Xiaomei and laughing at him! Then, Chen Jiannan stopped laughing wildly and began to bite Shi Xiaomei's jade body with his greedy lips. He saw this in his eyes, and the pain in his heart was like a heartbreak! He couldn't hold back his anger and ran desperately towards Chen Jiannan. However, he chased for a long, long time, but he never caught up with the lover thief who was not far ahead. In the midst of this chase, he had already seen with his own eyes that Chen Jiannan had obscenely sucked Shi Xiaomei's jade incense all over his body and the leaves of his limbs. His eyes gradually dimmed, and he felt his mouth dry and tired. It was the feeling and situation of "Kuafu chasing the sun", he drank water after puff and puff, and finally died of thirst.

The feeling in the dream is so ruthless and helpless. In the boundless sky, a poignant warning word finally sounded——

In the past, sound was better than silence, and now silence is better than sound.
