My future is to be an astronomer.

Everyone has his own ideal. If you ask me what my ideal is? I will tell you without hesitation that I want to be an astronomer. When I was lying in bed reading an encyclopedia as a child, I was suddenly fascinated by a blue star fan, that is, the earth. I immediately devoted myself to the ocean of astronomy, which lasted for several years. With the increase and deepening of reading astronomy books, my interest has increased, and I am more fascinated by wonderful astronomical phenomena, strange astronomical wonders and some mysterious phenomena. It seems to be an unsolved mystery covered with a thick golden veil. After my parents found out that I love astronomy, they bought many books about astronomy for me to read. After reading enough books, my knowledge of astronomy has been improved. Seeing that I had some basic knowledge, my parents sent me to the Youth Palace in Liu Ying Street to study, and specially bought me an astronomical telescope from Beijing to observe the moon and near-earth asteroids. The distance between NEOs and NEOs is equal, which greatly improves my knowledge and practical ability. For this ideal, I will work hard, learn all subjects well and work hard for my ideal. I believe my ideal will come true in the near future.

My dream is to be an astronomer. Everyone has a beautiful dream. My beautiful dream is to be an astronomer.

Explore more secrets of the universe.

After I became an astronomical scientist, just like some developed countries set up space stations in space, I took more people and animals to study and do experiments on them and found something useful to human beings. After I became an astronomical scientist, I discovered some planets to see if it could combine with something to produce oxygen, and then put something that can produce oxygen on that planet, so that human beings can survive on it. Our earth is no longer crowded. After I became an astronomical scientist, I recorded the time and position of the earth in a place. After a lot of data, I calculated the time when beautiful comets and meteor showers appeared for people to observe and study. There are many planets in the universe, some of which we don't know their names, and these unknown planets are not sealed constellations. I will seal all the stars we can see into constellations, so there will be more constellations in space. I will invent an observation like Zhang Heng. As long as I study hard, I believe that my ideal is not a dream from now on.

My dream is to be an astronomer. My dream of writing 600 words is so distant and mysterious to me ... becoming a scientist is an extraordinary career.

Scientists like Einstein, Galileo and Newton have great influence on the scientific community.

I admire them very much, so I want to be an astronomical scientist, discover life on Mars, observe distant planets and explore the vacuum universe … I grow up day by day and learn more knowledge day by day.

I learned about the great men "Emperor Taizong, Liu Bei, Kangxi ...", which taught me a lot about being a man.

Success is composed of hard work, persistence and talent, so I have created such a formula: realizing ideal = hard work+persistence+talent.

If a person has an ideal, has the talent cultivated since childhood, works hard to realize it, fails and persists, then the ideal will be realized.

I know from books that a living planet must meet the following conditions: 1, with a hard shell; 2. Biologically suitable temperature; 3. Have a proper atmosphere (mainly oxygen); 4. There is enough water; This must be a planet, and the central celestial body around it must be a stable middle-aged star.

The conditions of life are very bad.

I once imagined obsessively: "Will there be life on Mars? What is a living planet like? Could it be ... "I really want to solve this mystery, so I really want to be an astronomical scientist, to discover another home of mankind and to solve the mystery of the universe.

Of course, I know it is not easy to be an astronomical scientist. You must have a high degree, a strong thirst for knowledge and imagination, and a spirit of not being afraid of difficulties and failure.

"It's naive for a child to want to be a Japanese scientist!" Yes, it sounds naive, but I firmly believe that "as long as there is perseverance, iron pillars are ground into needles."

In order to realize this ideal, I have made a lot of efforts.

I bought The Magical Earth, The Mystery of the Universe, The Mystery of the Universe ... I read every book thoroughly and absorbed all the knowledge in it.

Once, I started reading at noon, and I felt that I had been reading for a long time. My father asked me to go down for dinner.

I was very surprised. I looked outside the house. It's already dusk.

That's how I absorb all kinds of knowledge every day, so that my ideal and reality are shortened continuously.

I keep learning experience and knowledge from life.

In learning, I listen carefully and speak actively; During the performance, I actively acted as a small host; In the debate, I will express my views and theories ... When I grow up, I will use this knowledge and strive to become a scientist.

"You can't learn all the knowledge without receiving the spring water", but as long as you are willing to learn, you can learn more knowledge.

I am like a fish, swimming freely in the future Wang Yang sea. I choose which future to choose.

But in this future ocean, there can be no storm, but I am full of confidence. I have the confidence to break through all difficulties, pursue my ideals, realize my ideals and win glory for my motherland!

My ideal composition requires about 400 words. Everyone who is an astronomer should have his own colorful ideals. Workers, teachers, police, doctors ... Every ideal is so beautiful, and everyone is so persistent.

For the sake of ideals, everyone is making unremitting efforts to realize and turn grand ideals into reality.

How naive and naive I was when I was a child.

And I never thought about what my ideal was.

I, daily growing, became mature day by day and began to think about my ideal.

I really want to be an astronomical scientist.

But most of those great scientists live in famous big cities, and I live in this little-known town. Even if I have ambitions, it is difficult to achieve them.

The ideal is so far away and mysterious to me ... becoming a scientist is an extraordinary career.

Scientists like Einstein, Galileo and Newton have great influence on the scientific community.

I admire them very much, so I want to be an astronomical scientist, discover life on Mars, observe distant planets and explore the vacuum universe … I grow up day by day and learn more knowledge day by day.

But in this future ocean, there can be no storm, but I am full of confidence. I have the confidence to break through all difficulties, pursue my ideals, realize my ideals and win glory for my motherland! (Very tired, take it)

The ideal of writing astronomer Zhang Heng's composition 100 is the spiritual pillar of life, the guide and motivation of life, the navigation mark of life and the belief in tomorrow.

A lofty ideal is the sun in one's heart, which can illuminate every step of life.

Since ideals play such an important role in life, how can they be lacking? When I was a child, I often listened to my mother tell stories about musicians such as Beethoven and Mozart. Oh, great! They devoted their whole lives to music, and their love for music deeply touched me.

This also made me make up my mind from an early age: I want to be an excellent musician when I grow up! I often sit alone in my spare time, and it seems that I can see many beautiful fragments: I walk along the beach, looking at the endless sea and looking for inspiration for music.

Suddenly, a cheerful smile appeared on my face, and I thought of it! So, I hurried home again and recorded the music quickly.

I played a wonderful song gently, great! I am very satisfied with my work.

A few days later, my solo concert opened.

On the stage, I selflessly played songs for the audience, which was so sweet. Thunderous applause rang out from time to time, and everyone was intoxicated ... If my dream came true, I must write more songs and play more songs, infect others with my own music, and create a more colorful life with music! But I understand that this is just my daydream.

A sail without a mast is a useless cloth; Ideals, if not put into action, are illusory fog.

If I really want to achieve it, I must work hard to have this brilliant day.

Without spring ploughing, how can there be autumn fruits? I will practice hard for my ideal, persevere and go forward bravely, and I will try my best to realize this ideal as a musician! I believe that the road belongs to people with ideals.

As long as I firmly pursue my ideals and let them shine, the road will extend under my feet!

More than 200 years ago, the German philosopher Kant said, "There are two things. The more you think about them regularly and persistently, the more you enrich your mind with their growing charm and reverence: the starry sky above my head and the moral law in my heart.

100 years later, in China, there was a man who pursued his life for the starry sky overhead.

He named an asteroid he discovered "Zhonghua" Star, which was the first time that China people named an asteroid. He organized and photographed the first total solar eclipse in China. He first proposed to study the return of Halley's Comet, in order to solve the historical unsolved problem of which year the "cutting week" occurred ... He is Yuzhe Zhang, the founder and famous astronomer of modern astronomy in China.

The doll in Furong Lane "meets" a comet, walks into Fuzhou Bamboo Workshop and passes by Garden Lane. A low and shabby old house is hidden at the end of a dark alley, which is Yuzhe Zhang's former residence at No.7 Furong Lane.

/kloc-One summer more than 0/00 years ago, in the open space of an old house in Minhou County, Fujian Province, every night, there was always a thin child looking up at the starry sky, recognizing the Big Dipper and the constellation with mysterious light, tirelessly and cheerfully.

Neither the frogs in the pond nor the sounds of friends playing hide-and-seek can distract him. He is Yuzhe Zhang, who likes to observe astronomical phenomena since he was a child and is fascinated by astronomy.

1February, 90216th, Yuzhe Zhang was born in Minhou county, Fujian province, and was the youngest of the five brothers.

When my father died at the age of two, I lived with my mother.

19 10 in may, Yuzhe Zhang was eight years old. When the world-famous Halley's Comet appeared in the sky, the scene of it dragging its long tail in the dark was deeply imprinted in Yuzhe Zhang's heart.

I couldn't bear the death of China's ancient studies, so I transferred to the Northwest Observation Team of Astronomy Department for 194 1 total solar eclipse.

Data Map "Astronomy is an ancient science in China, which was first developed in China. Its research scale has been brilliantly prepared thousands of years ago, but it has declined since then ... After nearly a hundred years, influenced by corrupt politics in the late Qing Dynasty and destroyed by warlords, astronomy, an ancient science, died out even more and was almost silent.

You care about national quintessence, support wing civilization and think deeply.

"Reading here, Yuzhe Zhang's heart trembled slightly. Is China really going to sink? Will astronomy and ancient learning die out in China from now on?

I have an incredible dream-I hope to have a pair of snow-white wings that can fly to the blue sky, the sea and every corner of the world, explore the mysteries of nature and create more advanced instruments.

First of all, I will fly to Europe, visit Germany, Britain and France, see the ancient and time-honored culture, and bring advanced science, culture and technology back to China.

Then, I will fly to Paris to see if the "Paris Tower" is so strong and impressive.

Then take photos, bring them back to China, and then have a whim to build the second "Paris Tower".

Then, I will fly to the United States and bring their superb medical skills back to China, so that the "war without smoke"-atypical pneumonia will never "go to war" in China.

Finally, I will fly to Iraq to watch the scene of bullets and send condolences to those who have lost their loved ones and family warmth, so that they can understand that the "flower of peace" is easy to destroy and must be cherished. ...

Astronomical knowledge composition Astronomical knowledge universe is mysterious, but human beings are also exploring and excavating, so let's get to know his preliminary knowledge! 1. The mass of some celestial bodies in a black hole is so huge that nothing can escape from it, even light.

Without light returning, the eyes can't see the object, so it is called a "black hole".

Two. People on the ecliptic earth look at the apparent path of the sun in the stars in one year, that is, the great circle of the ecliptic, where the earth's orbital plane intersects the celestial sphere, forms an angle of 23 degrees and 26 minutes with the celestial equator, and intersects with vernal equinox and vernal equinox.

Three. The angle between the two points on the celestial sphere of the yellow pole and the ecliptic is 90 degrees, and the one near the north celestial pole is called "North Yellow Pole".

The angular distance between the ecliptic pole and the celestial pole is equal to the ecliptic angle.

The North Yellow Pole is located at the center of the connecting line between Tianlong and the two stars.

Ⅳ. Zodiac: A long strip with 8 degrees (* * * width 16 degrees) on each side of the ecliptic on the celestial sphere.

The orbits of the sun, the moon and the main planets are all on the ecliptic.

To show the position of the sun on the ecliptic.

Divide the zodiac into twelve segments, which is called "Zodiac".

From the vernal equinox, they are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.

In the past, the zodiac and the zodiac were the same.

With the vernal equinox moving westward, the vernal equinox in Aries has moved to Pisces two thousand years ago, and its name is no longer consistent with the constellation.

ⅴ. Sanyuan includes Ziwei Garden, Taiwei Garden and Tianshi Garden.

Purple element includes the sky area near the north celestial pole, which is roughly equivalent to the area of arch star; Taiwei Courtyard contains some constellations such as Maiden, Houfa and Lion. Tianshi source includes snake man, five immortals, giant snake, skyhawk and other constellations.

ⅵ. Twenty-eight nights: seven nights in the east, seven nights in the west, seven nights in the south and seven nights in the north.

Twenty-eight hotels are also called twenty-eight stars or twenty-eight houses.

At first, the ancients chose 28 stars to compare the movements of the sun, the moon, gold, wood, water, fire and earth as observation marks.

The meaning of "lodge" is similar to the "palace" of the zodiac, indicating the position of the sun, moon and five stars.

In the Tang Dynasty, Twenty-eight Hostels became the main body of the twenty-eight celestial bodies, and these celestial bodies were still named after Twenty-eight Hostels. Different from Sanyuan, as a celestial body, Twenty-eight Hostels are mainly used to divide the ownership of star officials.

The 28 huts start from Kakuk and are arranged from west to east, in the same direction as the sun and the moon.

ⅶ, Dongfang Qisujiao, Kang, Bian, Fang, Xin, Wei and Qi; North Seven Nights: Dou, Niu (Petunia), Female (bearded female), Deficiency, Danger, House (Barracks), Wall (East Wall) Eight, West Seven Nights, Building, Stomach, Chang, Bi, Qian, Shen Jiu, South Seven Nights Well (East

Ten, seven nights in the north, cows, women, virtual, dangerous, houses, walls 1 1, auxiliary officials or auxiliary seats. In addition, there are some star officials who are close to these star officials and are closely related to them, such as tombs, detached palaces, ears, cutting, smashing, corpse accumulation, right jurisdiction, left jurisdiction and Changsha.

In the Tang Dynasty, there were 183 stars in 28 places, including auxiliary officials or auxiliary stars.

12. The cosmic velocity refers to the initial velocity necessary for launching artificial celestial bodies from the ground to the universe.

13, the first cosmic speed People call the speed of 7.9 km/s the "first cosmic speed" and also the "hovering speed". Below this speed, the object will return to earth under the action of gravity.

14, the second cosmic speed If we increase the speed to 1 1.2 km/s, this artificial satellite can travel to the interplanetary space of the solar system without being affected by the gravity of the earth.

People call the speed of 1 1.2km/s "the second cosmic speed" 15. If third cosmic velocity wants satellites to fly out of the solar system and go to other planets, it must speed up to 16.7km/s, which is the so-called "third cosmic velocity".

16, flat year and leap year Because the number of days in a tropical year is not an integer, the number of days in each year is different, some are 365 days and some are 366 days.

A year with 366 days is called leap year, and a year with 365 days is called average year.

February in leap year is longer than average 1 day, and so are other months.

Generally speaking, a year divisible by 4 is a leap year. If the year is an integer of 100, the year divisible by 400 is a leap year.

17, the number of days in a leap month is different between the lunar calendar and the solar calendar. There are about 365 days in the solar calendar and 354 days in the lunar calendar.

In order to make the number of days in a year the same, one month is added in some years of the lunar calendar, and the added month is called "leap month".

Because the Gregorian calendar year is only about 1 1 day older than the lunar calendar, it is impossible to add leap months every year. About 19 has seven leap months.

18, the tropic of cancer, the time for the earth to go around the sun is called tropic of cancer.

The tropical year is 365 days, 5 hours, 48 minutes and 46 seconds (365 days +09 days). This is only some superficial knowledge, and deeper knowledge-knowledge of the universe and the nature of the universe-needs our constant exploration, research and excavation! You can use subheadings.

Many people have their own dreams when they are young. They dream of becoming astronomers, soldiers, musicians, teachers, doctors and so on when they grow up.

Perhaps different from your dream, my dream is to be an excellent scientist when I grow up.

Every time I get sick and go to the hospital, I can see many patients waiting in line for the doctor's treatment, sometimes for hours or even a day.

Because it's not just doctors who auscultate, it's very troublesome.

So every time I see a doctor, I wonder if it is great to invent an instrument that can prevent bacteria from entering the body! Or invent a vaccine and inject it into people's bodies, so that bacteria can be prevented from entering people's bodies, people will not get sick and doctors can rest.

That's why I dream of becoming a scientist when I grow up.

When I told my mother my dream, my mother told me: "If you want to be a scientist, you must have extensive knowledge, be good at observation and be diligent in thinking;" Have the spirit of not being afraid of failure and being brave in climbing.

As the saying goes, where there is a will, there is a way.

"So in order to realize my dream as soon as possible, I must study hard and make progress every day.

Try to realize my dream as soon as possible.

Please indicate the source? My future is to be an astronomer.
