I am an integral part of the radio satellite.

Not long ago, China's first self-designed spaceship Shenzhou was launched in Inner Mongolia. Its successful launch marks that the development of China manned spacecraft has entered a brand-new historical development stage.

China's rocket launch technology is so high that even American satellites sometimes rely on China's rocket launch to succeed. Since Dongfanghong satellite went into space, China has successfully launched a considerable number of satellites, such as geosynchronous satellites, communication satellites and meteorological satellites. And successfully mastered the returning remote sensing technology, which is a new technology that only a few countries in the world have mastered. The successful launch of Shenzhou shows the rapid development and brilliant achievements of China in the high-tech field.

Listen to the teacher: The successful launch of Shenzhou, on the one hand, shows the progress of science and technology in China, on the other hand, it also plays its special value. That is to shoot the military bases and weapons distribution areas of most countries in the world, and know yourself and know yourself. China's science and technology has reached the leading position in the world, which can not help but arouse our interest, that is, study hard, strive to become a scientist when I grow up, and push China's science and technology to a higher level.

Shenzhou went to heaven, with our desire and pursuit of knowledge.

The satellite in my mind is 200 words, which can also make them blush! If I were a traffic safety satellite, I would have emitted ultraviolet rays a few days ago.

If I feel an overloaded car on the road, I will "transport" the overloaded goods back to their original place.

If I have supervision, I feel ashamed. Let them go where they can. When these students ride to the side of the road, the world will be better if one student rides against the advice of his classmates. He always paid attention to the situation of the earth and died on the spot. Our class carried out traffic safety education: one day several students came home from school.

If I see people or cars jaywalking, I will send out infrared rays to illuminate them. At this time, I thought to myself, until the police car came and towed it away, this infrared ray was amazing, not only could it stop people, but then a car on the right "bumped" and met the student a few meters away: I wish I were a traffic safety satellite.

The teacher talked a lot about the bloody tragedies of car accidents and deaths caused by traffic violations.

If anyone finds driving without a license, tell the driver to pay attention to safety and not to overload. One thing has been shaking my heart. I'm like a clairvoyant. I will look at Ma's beautiful earth in space and start the brake system of the car so that his car can't move on the road.

Each of us has our own dreams and ideals. Some people want to be a doctor, some want to be a soldier, some want to be a driver, some want to be a singer, and I want to be a respected scientist.

If I were a scientist.

I will invent a robot so that we don't have to do housework and worry about no one to chat with.

This robot can tell stories to children, all kinds of stories. This robot can be human, can take care of children for adults, can also teach people to keep fit, and can also teach children to read and study.

This robot can also do agriculture, help people sow seeds and harvest in autumn.

This robot doesn't need to be charged. It can absorb sunlight during the day, and it can also be charged by using the solar heat absorbed during the day.

If I were a scientist.

I will build more seeders, green the earth's ecology, and then sow seeds into the desert.

Invented many artificial rainmakers, sprinkled water on trees all over the world, and created a world for animals.

I will also invent cloning machines and clone more rare animals, so that the ecology can be balanced and the earth will become more beautiful.

If I were a scientist, I would make an eye TV. I can watch TV anytime and anywhere. If I want to watch TV, I can feast my eyes. If I like watching different TV programs, I can choose my favorite movie or TV with my eyes.

I will also invent a universal watch that can do whatever I want. As long as I start the universal watch, it will become a robot to serve you. This watch can also be used as a bodyguard. Whenever I meet bad people, I will attack them and call the police automatically.

If I were a scientist.

I will invent a spaceship. I will make two small flying machines in the spaceship, and I will install an automatic oxygen generator on the spaceship, so that I can breathe the air outside the universe and rebuild a satellite of the spaceship. I can investigate in front of the ship and send the information to the ship's main engine when I get the news. I will also invent a lightweight spacesuit with protective equipment, so that I can move freely in the galaxies of the universe and not be so heavy.

I will also install an automatic repair machine on the spacecraft, which can repair the spacecraft at any time, and I will also install a device that can detect aliens on the spacecraft.

If I were a scientist, I would invent a machine that can communicate with animals, so that people and animals can become friends.

We can talk to each other and understand the feelings and thoughts of animals, instead of doubting each other.

I will also invent a machine that can detect ancient cultural relics, so that we don't have to look for them easily and can show those ancient cultural relics earlier. I will also invent a machine that can dig ancient cultural relics, so that I can dig early and increase insurance, and I don't have to be afraid of weapons hidden in ancient tombs.

If I were a scientist, I would invent many machines.

For the benefit of mankind, for the benefit of our planet and for the benefit of the people of the whole country.

It was a quiet night. When I opened my eyes, I saw Uncle Yang Liwei calling my name in front of me. I was shocked at that time. Uncle Yang Liwei said to me, "Don't be afraid. I want to take you on a trip to the moon.

"I just put down the heart, the spacecraft quickly into the moon. Uncle Yang Liwei led me out. Just after I went out, my feet floated around, but I was very nervous. Uncle Yang Liwei told me: "Don't be afraid, staying on the moon is a natural phenomenon. You saw me too.

"Slowly my heart suddenly excited.

This is Uncle Yang Liwei coming up to me like a spacewalk and saying, "Son, we are going to explore the mysteries of space now.

"I said cheerfully," all right.

"shout.

Slowly, when we arrived in space, Uncle Yang Liwei put on my spacesuit. When I put on my clothes, I really look like a big fat bear. I can't help laughing. When I came to space, Uncle Yang Liwei told me the mystery of fairy tales such as "A moth flies to the moon". Now China's aerospace industry is booming and exciting.

The sons and daughters of China have turned the myth of thousands of years into reality and realized the dream of China people landing on the moon. Uncle Yang Liwei told me that China successfully launched the first manned spaceship Shenzhou 5 on June 5438+1October 3, 2005, and the second manned spaceship Shenzhou VI on June 5438+1October 2, 2005.

Uncle Yang Liwei also told me that besides him, Nie Haisheng, Fei and other space heroes brought the five-star red flag into space, which proved to the world that the Chinese nation is becoming stronger and China's space industry is becoming more brilliant step by step.

I can't help but feel a quiver. It turns out that China is so great, which makes those countries that despise us look brand-new, thinking that China is not easy to mess with! "Just when Uncle Yang Liwei said he was going to the moon, I suddenly heard a familiar voice," Baby, get up and eat! "I suddenly opened my eyes and my mother was standing by my bed." Oh, what are you doing, mom? We will go to Mars soon! """You're still going to Mercury. Get up and eat! "When I came home from school, I immediately put down my schoolbag and began to recall the last time I assembled a model plane. On my seventh birthday, my parents bought me a jigsaw puzzle of an airplane model. After dinner, I couldn't wait to open the package and take a look at this pile of debris. I have a headache.

My father sitting next to me was unhappy and came over and asked, "What's the matter? Let's spell it together.

"Dad said to me," How can you do this without reading the instructions? After a while, he also found it difficult, but he said, "If we work together in Qixin, Qi Xin will surely succeed.

"I listened to, immediately squat down beside him, he read the instructions, while spelling, a nose spell out in a short time.

I got up the courage and said, "Dad, I understand. I'll spell it myself.

""well, good boy, help yourself.

"Dad stroked my head and encouraged me to say.

Success must belong to those who persist. After my efforts, I finally put the plane together, and I have unspeakable pride in my heart. If I grow up, I can fly such an airplane to soar in the blue sky and conduct scientific experiments. After a while, I recovered and found my mother staring at me in a daze. I suddenly blushed and pretended that nothing had happened and asked her, "Mom, why didn't you stand next to me and tell me?"

"My mother giggled. I look innocent. My mother put the fruit in front of me and left. I thought, "Well, that scene was really funny.

"But then I thought," Well, last night's dream was really great, but it wasn't true.

"But this will not hinder my dream of exploring the mysteries of the universe.

I am a satellite on the mountain.

A long time ago, a lively and lovely little girl planted me on this mountain and watered me every day.

After more than a month, I slowly grew taller.

I gradually grew into a leafy tree.

In summer, hardworking people enjoy the cool under me, and people are laughing and laughing below, which is very lively.

However, people hacked my brothers and sisters to make money.

Year after year, generation after generation, the trees on the hillside are decreasing, and the land of * * * is expanding.

The storm suddenly struck, flash floods broke out, washed away the villages at the foot of the mountain, washed down many houses and brought great disasters to people.

Because people cut down many of our own kind, we can't resist the wind and dust.

When the sandstorm comes, people dare not walk in the street, cars scrape on the road, and planes stop flying ... Because people cut down a lot of trees, we can't create fresh air, so people can only live in turbid air, and various diseases follow ... Ah! I appeal to you, please don't cut down trees.

If you do this, you will get into trouble, too!

I want to develop a satellite. I am a little boy who loves to do things. I like to make some strange little things. Today, when I am idle at home, I will open a "satellite".

I took out scissors, white paper, adhesive tape, double-sided adhesive tape, jelly box and other tools, ready to start construction! First, fix the two jelly boxes mouth to mouth with adhesive tape, then cut out two rectangular strips of paper about eight centimeters with scissors on white paper, and then stick them on both sides of the jelly boxes respectively, and the solar windsurfing is completed.

Cut a small disc with a diameter of 3 cm, paint it red with a colored pen and stick it under the "satellite".

Also gave it a name called "Optical No.3" and stuck it on its side.

Finally, stick a cone-shaped cardboard on it, and the satellite will be ready! I really want to sit on it and travel in space.

If I were a traffic safety satellite, our class had a traffic safety education a few days ago.

The teacher talked a lot about the bloody tragedy of car accident death because of violating traffic regulations. One of them has been shaking my heart: one day, several classmates came home from school and rode to the side of the road. One classmate continued riding despite his classmates' dissuasion. At this time, a car came on the right, and the student was knocked out a few meters away and died on the spot. At this time, I thought to myself: If I were a traffic safety satellite, what would it be? If I were a traffic safety satellite, I would look at the beautiful earth in space, and I would always pay attention to the situation of the earth like a thousand eyes.

If I find someone driving without a license, I will emit ultraviolet rays and start the brake system of the car so that his car can't move on the road until the police car comes to tow it away.

If I sense that there is an overloaded car on the road, I will "transport" the overloaded goods back to their original places and tell the driver to pay attention to safety and not to overload.

If I see people or cars jaywalking, I will illuminate them with infrared rays. This kind of infrared ray is amazing. It can not only make people stop, but also make them feel hot and blush, and then let them go where they can.

If there is my supervision, the world will be better!

I met someone from 100 to 105.

No matter whether there are difficulties or not, whether there is sadness or not, she has always been with her.

Only when I have negative emotions can I find that she is always around.

Her sense of existence is so small that she doesn't care and doesn't even know where she is.

Because I am too fragile, because I am too fragile, so she came.

When I was sad, I met someone.

No matter whether there are difficulties or not, whether there is sadness or not, she has always been with her.

Only when I have negative emotions can I find that she is always around.

Her sense of existence is so small that she doesn't care and doesn't even know where she is.

Because I am too fragile, because I am too fragile, so she came.

Sad time

How to write a composition about Beidou satellite navigation? I almost caught fire in my mouth, but my mother stopped me ... My mother dragged me to the restaurant.

When I arrived at the noodle restaurant, I just wanted to enter the house, and suddenly I thought of our nickname-Spicy Sister. I quickly added a spoonful of Chili powder to my sister's bowl and asked angrily, but pretended that nothing had happened.

I broke out in a cold sweat because they both like spicy food very much.

That's not true.

It won't be long.

I finally stayed up until after dinner: "Do you like spicy food?" .

It has already done so.

Keep eating noodles. Yesterday, my sister and I secretly went to the spicy restaurant to eat beef noodles. After my sister took a bite, her face turned red this time, but she kept staring at me like a funny puppy. We immediately ordered two bowls of super spicy beef noodles and the waiter brought them.

I thought my sister would eat more happily, and my mother saw her face.

Before we had time to eat, the proprietress urged us to pay the bill.

My sister, who has always been reluctant to spend money, did not hesitate to take money to the counter to settle the bill.

I sat there alone.

I dare not look into my mother's eyes.

I didn't expect that.

"okay.

Seeing my sister like this, I stretched out my tongue.

When she got home, she didn't stop. She took my hand and hurried home and gave me half a sausage wrapped in spicy powder, so she guessed half? "I nodded, then you come with me.

"Mom pulled me to the table again.

Self-made satellites consist of 400 words, which are used as artificial earth satellites for radio communication relay stations.

According to whether there is a communication transponder, it is divided into passive communication satellites and active communication satellites; According to the orbit, it is divided into stationary communication satellites and non-stationary communication satellites; It is divided into international communication satellites, regional communication satellites and domestic communication satellites according to service areas; According to the purpose, it is divided into special communication satellites and multi-purpose communication satellites.

Using satellite for radio communication has the advantages of long communication distance, large capacity, good quality, high reliability and strong flexibility. It can transmit telephone, telegraph, data, images and faxes, and is widely used in international, domestic or regional communications, military communications, maritime communications and television broadcasting, spacecraft tracking and data relay. It is an important means of modern communication.

1958 18 In February, the United States launched the world's first experimental communication satellite "Skol".

At present, countries with communication satellites include the former Soviet Union, Britain, China, French and German.

China launched the geostationary orbit test communication satellite for the first time on April 8, 1984.

Praise China Aerospace for China Aerospace, I am proud, I am proud! * * * once said: "If China didn't have atomic bombs, hydrogen bombs and satellite launches from the 1960s, China wouldn't be an influential country and wouldn't have its current international status.

These things reflect the ability of a nation and are also the symbol of a country's prosperity and development.

The remarks of "* * *" illustrate the importance of the aerospace industry.

However, only after giving can you get a reward.

Qian Xuesen and others, with the hope of a strong future for the motherland, worked hard and accomplished tasks that seemed impossible for foreigners to China under the condition of complete independence, and set up the first milestone in China's space history-the successful launch of Dongfanghong-1.

Starting from Qian Xuesen and others, after the launch of the Dongfanghong-1 satellite, our people, relying on the indomitable spirit, constantly improved satellites and rockets and created great achievements one after another! I am proud, I am proud! During the seven years of the manned satellite program, many astronauts just want to have a good sleep.

But such a simple wish is also an unattainable luxury for many people.

Chinese astronauts driving rumbling cranes into space must race against time for the country's ideals! Looking at these tired workers, I have a kind of respect in my heart. For them, for the aerospace cause of the motherland, I am proud, I am proud! September 5, 2008, 2 1: 00, 10, 4 seconds, 988 milliseconds, still in the cold night on the mighty Gobi.

There was a loud noise from the depths of the desert, and an orange fireball lifted the silver dragon shining in the cold wind from the vast Gobi desert and pointed it at the sky.

Huge fireballs lit up the whole Gobi desert.

The flame gradually turned purple, and the silver dragon became a golden dragon under the contrast of this flame. The four big characters on it jump in front of people-Shenzhou VII.

The hopeful golden dragon carried astronauts Zhai Zhigang, Liu Boming and Jing Haipeng into boundless space.

At this time, cheers came from Jiuquan Satellite Launch Center, the launch point of the spacecraft, because the spacecraft successfully separated the arrow from the ship after 583 seconds of launch and entered the predetermined orbit at a predetermined height and speed.

Astronaut Zhai Zhigang completed the new scientific problem of extravehicular activity and turned a new page in China's space history.

What is behind China's great space career? This is the core of the unity of our billions of people; It is the hope left by our old ancestors; It is a symbol of the prosperity and strength of our country.

As a China person, I am proud, I am proud! ...
