I had already decided to enjoy the moon tonight, and before it was dark, my sister and I couldn't wait to urge my uncle and aunt to eat quickly, so that we could move to the roof as soon as possible. Tonight is the fifteenth day of the eighth month of the lunar calendar, which is the Mid-Autumn Festival, also known as the Reunion Festival.

Before the uncle and aunt had eaten enough, the elder sister took the lead and ran up to the roof with a straw mat in her arms. Not far behind, I also ran after with a mooncake in my left hand and a fruit in my right hand. I blamed my uncle and aunt in my heart: How did you two do it, slowly dragging it out, slower than a snail.

We are a teacher's dormitory building in a vocational and technical school. There were already three or four families of children on the roof of the building, all of whom had set up to admire the moon, but there was not a single adult in sight. I looked around, and saw that more than a dozen people had gathered around my brothers and sisters on the spacious sports field on the ground in front of the building. In the distance, on the banks of the Xixi River, the usually deserted and overgrown open land has been crowded with people from the city. In the basic college on the far right side of the building, several lights are brilliant, judging from the noise and sound of the stereo, the enthusiasm of these college students' brothers and sisters for moon viewing is no less than that of our children. On the roof of the teacher's dormitory building near the right and the residential building behind, you can see people in groups of three or five, occupying the highest point. Only the warehouse of the agricultural material company on the left seems a little quiet. Everywhere in the crowd, there are their favorite mooncakes, as well as all kinds of fruits, peanuts, candies, biscuits, sugar cane, drinks, and some with cameras and binoculars.

My sister and I found an open place, laid out a straw mat, and placed mooncakes and fruits in the center of the straw mat. It was getting dark, but there was not a moon yet, and there was not even a star in the team. Tropical Storm Vicente has just passed tonight, and although the rain has stopped, the wind is still blowing. There are only thick black clouds in the sky, and it seems that there will be no moon tonight.

I don't know how many quarters of an hour passed, and the uncle and aunt slowly walked up with a knife and tea. Seeing that our mooncakes and fruits had already lost our soldiers, Uncle said humorously: "The children under the moon goddess are awesome, they go to the battlefield to kill the enemy, and they don't need to use knives and guns." The people around laughed. My sister rushed to say: "Apollo 11, the brother of the sun god, is a great one, carrying people to help mankind realize the dream of Chang'e to the moon." ”

"When is the bright moon, ask the wine to the sky......" On the left side of the sports field in front, I don't know that the brother who studied secondary school sang a tenor. I don't know if I came up with everyone's thoughts, and gradually a few people sang with him.

"The fifteenth moon, shining on the side and taking care of the hometown, you miss me on the quiet night, I miss ,......" The song on the left just fell, the bright moon in the sky came out through the clouds, and a group of people on the right sang in chorus, as if to overwhelm the song on the left.

"Ah! they're going to fight. Uncle said.

Sure enough, the chorus on the right was just halfway through the song, and the group on the left sang 'Moonlight Shining' again. 'Moonlight Shines' was not even halfway through the song, and the black clouds obscured the moon again, and the group on the right immediately sang 'Hear the Moonlight'. While watching the moon that is like a distant appearance, we are tasting moon cakes, and we are enjoying the singing of our brothers and sisters in vocational and technical schools. It's so beautiful, as if the moon exists for me, the moon cakes are made for me, and the song is sung for me.

Suddenly, the college students' brothers and sisters in the basic education college on the right sang loudly, which seemed to be a response to the technical secondary school brothers and sisters in the vocational and technical schools here. What 'the moon is hazy and the bird is hazy', what 'the moon represents my heart', what 'the moon walks and I go'....... One after the other, some are accompanied by drum instruments. My sister, who loves music, lost no time in introducing me to the piano music 'Moonlight Song' that Beethoven improvised for the Rhine River, and the guitar accompaniment was 'Moonlight' sung by Zhou Huajian. In the sound of singing and music, there is also the sound of poetry and lyrics: for a while, it is 'the bright moonlight in front of the bed', for a while, it is 'the night chant should feel the moonlight cold', for a while, it is 'raise a glass to invite the bright moon', for a while, there is 'the moon is cloudy and sunny', and for a while, there is 'the old country is unbearable to look back at the moonlight'. It is really a song to praise the moon, and a poem to sing the bright moon. It's a pity that I can't sing the song of the moon, and I can only recite the poem of the bright moon', or I really want to have a poem with them, and the north and south compete for songs.

"There is a little white boat in the sky, floating to the west, what is it?"

"It's the moon. ”

"Sometimes like a disc, sometimes like a sickle, sometimes hanging from the treetops, sometimes falling halfway up the mountain. Hit a planet. What is it?"

"It's the moon. "The adults and children of the neighbor on the left are showering under the moon, admiring the moon and tasting mooncakes while guessing riddles.

"Moon Gong, Moon Mother, your knife is blunt, my knife is sharp, I don't know how to cut your ears. "There was also the sound of adults teaching children to recite nursery rhymes from the warehouse of the agricultural materials company.

“...... Chang'e didn't wait for Hou Yi to arrive, so she ate all the elixir given by the Queen Mother, and she floated up and floated towards the sun. It was almost the sun, she was afraid that Emperor Yao would punish her, and she was afraid that the immortals would accuse her, so she didn't dare to go to the sun. She looked at the Moon Palace, and saw that there was an osmanthus tree, under which Wu Gang was cutting down the tree, and Xiaobai was not colliding with medicine, a peaceful and happy scene. She thought about it for a while, then turned around and floated towards the Moon Palace...... "In the residential building behind, there was a voice telling the story of 'Chang'e running to the moon'.

At this time, the black cloud broke several holes, and the bright moon was in the sky in one hole, as if we were looking at the bright moon in the well. Venus should be down, Jupiter may not have come out yet, the light of the Big Dipper, the North Star, and the red glow of Antares have been drowned out by the black clouds, and there are only a few faint stars in the sky that appear from the holes in the black clouds, I can't name them, only Vega can make out them.

What a wonderful and harmonious social scene composed of the bright moon, the stars, the songs, the poems, the riddles, the children's songs, the stories, etc.! I enjoyed it and reveled in the moonlight. I think that if Chang'e floats by at this time, she will definitely be more nostalgic than the Moon Palace.

My sister suddenly asked my uncle, "Why is the moon cloudy and sunny?"

Uncle replied: "First of all, we must understand what is called cloudy and sunny, the so-called yin refers to the meaning of the moon is dark and vague, the so-called sunny means that the moon is clear and clear, the so-called circle refers to the meaning that the moon is round and complete (such as the moon we see around the fifteenth), and the so-called lack means that the moon is defective and incomplete (such as the moon we see at the beginning of the month and the end of the month). Cloudy and sunny is caused by the cloudiness of the atmosphere, the cloud thickness is cloudy, and the absence of clouds is clear; the lack of circle is caused by the different surfaces of the moon reflecting the sun's rays, and the frontal (referring to the surface we see) is round, and the side reflection is missing. ”

"What about the back reflection?" asked my sister again.

"The reflection from the back side is something that we don't normally see, but if the moon happens to be connected to the sun and the earth, it becomes an interesting astronomical phenomenon......

"It's a solar eclipse. Before the uncle finished speaking, the sister rushed to answer.

"Yes. ”

I thought that the earth has a rotation and an revolution, so I asked my uncle, "Does the moon also have a rotation and revolution like the earth?"

"Yes. ”

"Why do we always have the same face when we see the moon, except for the changes in the clouds and sunshines?"

That's a good question. The uncle replied, giving his sister a thumb on his wings, and continued, "This is not a contradiction, but a wonderful coincidence." ”

"What kind of wonderful coincidence?" I asked.

"This is because the period of the Moon's rotation is exactly equal to the period of the Moon's revolution around the Earth. ”

"Can a man live permanently on the moon?" I asked again.

"Not now, maybe later. ”

"Why?"

"Because there are no environmental conditions for human existence there. ”

"What are the environmental conditions for human survival?"

"First of all, there must be water, secondly, the right temperature, thirdly, the right amount of oxygen, fourth, food, and none of these moons can satisfy. ”

"Will you be satisfied later?"

"In the future, we can build a space station there, just like the current space station, to create environmental conditions for human survival. ”

"The moon must be beautiful there, right?" asked my sister again.

"Yes, but compared to the earth, which has blue skies and white clouds, beautiful mountains and rivers, and thriving creatures, it is much worse. ”

"Isn't that heaven?"

"No, heaven is just a good wish. Astronauts who have been to the moon say that there is brown dust everywhere and the sky is pitch black. There was no air there, the two of them could not hear each other talking close together, and the temperature reached more than 80 degrees during the day and minus 150 degrees at night. There are only mountains, no water, no rivers and no seas, no flowers and trees, and no insects, snakes, birds and animals. It was a desolate, lifeless, dead world. Compared to the beautiful earth, it is not a paradise, but a real hell on earth. ”

"Why do people want to go to the moon and enjoy it?"

"Because whoever owns space owns the future, and the moon is the first base station for human beings to go to the vast space. Moreover, experts believe that despite such harsh environmental conditions, the Moon is still the most ideal place for human habitation on the planet outside of Earth that people perceive. In this sense, the moon is beautiful. ”

"Ah, how nice it would be if we could take the moon!" said my sister and I with sighs.

"Study hard, maybe the moon belongs to us. Uncle said.

At night, the bright moon ran out of a big hole again, shining above my head, shining brightly on the earth, and even the buildings two or three kilometers away were clearly visible. I'm sweating profusely and I'm feeling a little cold now, but my heart is very hot. Because of the bright moon and uncle, they accompany me. When I was tired, I slept on the straw mat under the quilt and continued to admire the big round and bright moon.

Suddenly, I got on the Chang'e-108 lunar spacecraft and flew to the moon. I stood on the surface of the moon and saw the dark sky. The sun shines brightly in the dark sky, illuminating the moon very brightly. On the surface of the moon, covered with brown dust, there are round, elliptical and prismatic buildings everywhere, and on each building there is a five-star red flag. In the round buildings, there are many animals: cute giant pandas are eating green bamboo leaves freely, peacocks are spreading their wings and opening the screen, Xiaobai is jumping, black bears are wrestling, red-crowned cranes are wading in the water, dinosaurs are chirping, and birds are flying ....... The oval-shaped buildings were filled with turnips, loofahs, corn, and many other plants that I didn't recognize. I saw that the radish was as tall and big as the children in kindergarten, and the loofah was as thick as the mouth of the bowl and more than three meters long. In the prismatic building, there are various factories, research rooms, and observation stations. Workers, researchers, observers are all scientists. They all took their places, and when they saw us coming, they all welcomed us in standard Mandarin and greeted us. In each building, there are computers connected to the space network for video calls to family on Earth, the space station, Mars, and Jupiter. It's full of life and beautiful surroundings, and it's unforgettable. I scoffed at my uncle, "You're wrong. You don't know how to pretend to understand. You don't know the true face of the moon, only because you are on Earth. I saw that my uncle was not annoyed when he heard this, but just smiled slightly, walked towards me, raised his hand and pushed me hard. I lost my balance all at once and fell off the ground......

Ah——! I screamed and woke up, it turned out to be a dream. I saw my uncle laughing and pushing me and saying, "It's midnight, go back to the house and sleep, I have to go to school tomorrow." ”

I told Uncle about my dream.

Still laughing, Uncle said, "Remember Robert's famous saying: Yesterday's dreams can become today's hopes, and tomorrow's realities." Now that Chang'e to the moon has become a reality, and my country's Chang'e moon plan has also been launched, I think your dream will not always be a dream in the future, nor will it always be a myth. May your dreams come true!"
