Students, what is your's ideal? Maybe you want to be a people's policeman to protect people's safety; Maybe you are a considerable teacher, imparting knowledge to more children; Or maybe you want to be a doctor to heal the wounded and rescue the dying, so that more people are no longer afraid of diseases. And my ideal is to become an astronaut exploring the universe and explore more mysteries of the universe.

Since China successfully launched Shenzhou VI in 2006 and Shenzhou VII in 2007, I have been full of infinite yearning for the mysterious universe.

2006 is a memorable year for China people. Uncle Yang Liwei finally became the first astronaut in China who could go into space after screening at different levels. He took China's space technology a step forward. After the launch of Shenzhou VII in 2007, China took a big step in space technology. Astronaut? Y Zhigang, Liu Boming and Jing Haipeng successfully entered space from Shenzhou VII. Although they took a small step, they took a big step. China has produced one space hero after another, and they have made great contributions to China's space science and technology. I am full of cold respect for these space heroes, so I pay more attention to the information of the universe.

I remember one day not long ago, I was watching TV at home. Knowing that Nanning will see the whole process of partial solar eclipse. After watching the partial solar eclipse, I went to consult a lot of information about the universe. I saw the boundless universe and scientists using the soil brought back from the moon to cultivate big and strong vegetables and fruits. I think it is more convenient for astronauts to cultivate all kinds of plants on the moon, isn't it? From this, I strengthened my belief in exploring the universe.

I know such a dream is impossible. Only through hard work can we realize our ideals. Being an astronaut should also have a strong body and a hard-working spirit. At the same time, being an astronaut requires patience and firm willpower. And what I am thinking about now is not how to accomplish these goals, but what I should do most now is to study hard. Only by learning knowledge well can I realize my ideal. In the future, I will definitely work harder to build a strong body and explore new knowledge. Boarded the mysterious boundless universe with rich knowledge and strong physique.

Everyone has his own ideal, and I am no exception.

Some people want to be scientists when they grow up; Others want to be writers; Others want to be inventors ... I have a great dream to be an astronaut when I grow up.

At night, I looked up and saw the night sky: countless shining little stars set off a disk-like moon.

Looking at it, I couldn't help falling asleep: it was twenty years later.

The newly-developed "Moon 1" will be launched at 9 pm on August 18, and I am honored to be selected as an astronaut.

I receive cruel training every day and come home exhausted and weak every day.

Although training every day is very tiring, I feel a sense of relief and pride at the thought of doing it for my motherland. But I'm still looking forward to the early launch of Lunar 1.

But now, I must keep training and get fully prepared for the launch.

That day finally came "3,2, 1!" I was sent to the moon excitedly.

As long as I think that I represent the 65.438 billion people of China, I can't help crying.

After a long journey, I finally came to the moon! The book says that the lowest temperature on the moon is 100 degrees Celsius and the highest temperature is-170 degrees Celsius, but I feel similar to the temperature on the earth in the clothes carefully developed by the staff ... "Xiaoxiao, go home and sleep quickly, don't catch cold!" "Oh, I know mom.

"I was awakened by my mother and found that it was just a dream; But how I wish it were true! But I understand that if it is true, I must study hard from now on, and I must study hard when I grow up to serve my country!

Before the composition on space flight, Yang Liwei confided his heart to the soldiers of the whole army when answering a reporter's question at the press conference of Jiuquan Satellite Launch Center.

Our reporter asked: what do you want to say to your comrades in the three armed forces through the military newspaper? Yang Liwei: As an astronaut, I am a soldier of the Republic of China first. As a soldier, through so many years of training and education, I believe that in carrying out this task, I will be able to carry forward the glorious tradition and fearless revolutionary spirit of the people's army, obey orders and commands, overcome all difficulties and resolutely complete the task.

I also want to thank our comrades-in-arms of the whole army for their encouragement, care and love through the military newspaper, and please rest assured that I will live up to your expectations and add color to our military flag.

"For the peace and progress of mankind, China people came to space!" On the occasion of boarding the Shenzhou 5 manned spacecraft, Yang Liwei, the first astronaut in China manned space flight wearing a spacesuit, wrote this sentence enthusiastically for reporters.

The Chinese are coming, and Yang Liwei is coming! June 65438+10/October 65438+May 9, 2003, with the 38-year-old Lieutenant Colonel astronaut Yang Liwei flying into space in a manned spacecraft designed and manufactured by China, the Chinese dream of thousands of years has finally come true, and China has become the third space power to send astronauts into space after Russia and the United States.

The whole world has remembered the name of a China person-Yang Liwei.

Flying fighter for ten years1965 June 2 1 day, Yang Liwei was born into a scholarly family in Suizhong County, Liaoning Province.

Yang Liwei's father was a college student who graduated in the early 1960s.

My father became a teacher first, and then he did administrative work in an agricultural and sideline products company in Suizhong County. My mother worked as a Chinese teacher in a middle school in the county until she retired.

He also has a sister and a brother. Five people in the family live in harmony and live a comfortable and peaceful life.

"Doing things in a down-to-earth manner and being an honest man" are the requirements of Yang Liwei's parents.

As a child, Yang Liwei is smart, quick-witted and has a doll head.

When he graduated from primary school, he was admitted to the top class of the county key middle school with excellent results, and participated in the county middle school mathematics competition many times, winning many awards.

1In the summer of 983, 18-year-old Yang Liwei was admitted to the Eighth Flight Academy of the China People's Liberation Army Air Force.

During his four years of college life, his academic and training achievements have been excellent.

1987, Yang Liwei graduated from the Flight Academy and became a fighter pilot in a division of the Air Force.

With natural intelligence and hard work, he quickly became a top pilot in the division and later became an excellent fighter pilot.

10 years, he flew from north China to northwest, and from northwest to southwest. The blue sky of Wan Li motherland left his vigorous figure.

1in the summer of 992, Yang Liwei's unit came to an airport in Xinjiang to perform training tasks.

That day, he was flying eagles at an ultra-low altitude over Lake Aiding in Turpan.

Suddenly the plane made a loud noise, and the instrument showed that the cylinder temperature suddenly rose and the engine speed dropped sharply! Yang Liwei understood that he had encountered a serious "air parking" failure, and one of the aircraft engines did not work! At an emergency, Yang Liwei was unusually calm: Be sure to fly the plane back! He firmly grasped the joystick, slowly closed the throttle, and drove a fighter plane with only one engine, climbing up a little.

500 meters, 1000 meters, 1500 meters, the plane crossed Tianshan Mountain and flew to the airport.

Near the runway, the rest of the engines didn't work either.

He took decisive measures to release the landing gear urgently and successfully lowered the fighter plane that had completely lost power.

An abandoned pen (an abandoned pen) The owner bought a one-yuan pen.

Once the owner writes hard, the nib retracts and is left in the drawer of the computer room.

The pen cried in the computer room. The pen cried sadly for several days. One day, it said strongly, I will put up with others to fix me, and I will get through loneliness.

Every time the school students came to the computer room, they didn't see the pen. Only three students saw the pen and threw it on the ground.

The pen sank silently.

On one occasion, the owner took out paper from his schoolbag to write something, and when it was full, he threw it in the drawer of the computer room.

Now, the pen is not lonely.

Talk with a pen and paper.

Paper said angrily: "the things that the owner doesn't want are thrown everywhere."

"Pen speaks for the host:" The host lost us for a reason.

"Paper jilted to jilt mouth said:" cut! The last time I saw her, the toilet paper she used was thrown down and hit the classmates in the front row.

"The pen explained," The master wants to throw it into the drawer, and then he will go to the garbage corner and throw it into the trash can after class.

But there are her classmates' books in the drawer, for fear of getting dirty, forgetting to throw the trash can will be scolded by her classmates.

Hearing this, the newspaper said, "What's going on between us?" The pen said, "Let's talk about you first.

"explained:" the master draws something on you and throws it anywhere. I hope other students will be surprised to see it and say, who painted it? That's great. I want to pick it up for collection.

"Paper smiled and said," I see, the host is an interesting person.

The pen itself explained, "My pen tip has shrunk into a pen tip, and my master really wants to repair it, but he is afraid that I will damage it.

The master will buy a new pen to solve her problem. "When they finished, they all sighed and said," We have to wait for others to throw us away.

"They continue to chat, waiting for others to throw them away.

Write an imaginary composition of 500 words. My understanding of space flight is superficial. I think flying planes and rockets into the sky is space flight. The research in the space field is very extensive and in-depth. No matter how deep or shallow my understanding of space flight is, I like space flight very much.

I remember that my favorite toy as a child was an airplane, and now I have two well-preserved remote-controlled airplane models at home. I still remember when I was in the middle class of kindergarten, my grandfather and I made a rocket model and watched the exhibition in the whole kindergarten. In primary school, I joined the model airplane interest group, in which I made six model airplanes.

When the model plane I made flew in the sky, I thought of Uncle Yang Liwei, who traveled in space in a manned spaceship built by our country. This pioneering work has won us honor in China before the whole world.

With the continuous growth of age and knowledge, my understanding of space flight has gradually deepened, and at the same time, questions in my mind have followed, such as: How did a rocket fly without wings? Will the satellite fall into the sky? Another example: Why can manned spacecraft travel in space? ..... With these questions, I bought some encyclopedias about "Universe, Space and Natural Science".

Through the study, I initially learned that the rocket is an aircraft that uses the engine to inject high-temperature and high-pressure gas backward to generate force and get forward thrust, so as to move forward. Generally, it consists of three parts: power system, control system and structural system.

Satellites and space probes are unmanned spacecraft with highly complex automatic control devices. So far, they have visited the moon, Venus, Mars and Halley at close range or on the spot, and achieved fruitful results, so people call them "scouts of cosmic information".

In addition to launching satellites and detectors into space, humans also want to fly into space. Manned spacecraft is one of the tools for human beings to travel in space. It generally consists of cockpit, track module, service module, docking module and emergency rescue device.

The cockpit is the core of the spacecraft, the orbital module is equipped with various experimental instruments, and the service module is the place to provide life support for astronauts.

Manned spacecraft can carry out space activities independently, and can also serve as a "ferryman" between the ground and the space station, and can dock with the space station or other spacecraft for joint flight.

Tiangong-1 and Shenzhou-8, independently developed by China, successfully docked in space for the first time at 1 1 36 am on October 3. This is the third country in the world to master the automatic space rendezvous and docking technology after the first rendezvous and docking test between the United States and Russia in more than 40 years. This shows that our country's space technology has reached the top level in the world, and I am proud of it. At the same time, I love space more.

I am a child and the future of my motherland. I know that there are still many mysteries waiting for us to explore and discover in the universe, and there are still many difficult problems waiting for us to understand and overcome the key problems in the space field. Therefore, in order to realize my beautiful ideal of exploring the universe in space and make contributions to my beloved space career when I grow up, I will study hard scientific and cultural knowledge, firmly master excellent skills and strive to be an excellent young pioneer from now on.

...

This composition tells the adventures of astronauts in less than 500 words. "Blue sky, white clouds, flying a beautiful vulture.

"This is a wonderful description of astronauts that I read in books.

Let me yearn for the blue sky and white clouds.

Each of us has our own ideals.

Some people want to be generals in the future, leading thousands of troops and horses; Some people's ideal is to be a teacher and cultivate thousands of peaches and plums in Qian Qian; Some people dream of being a doctor and can save lives; My ideal is to be an astronaut, who can travel in space and fly his dreams.

The beautiful space gave me a lot of reverie.

How do white clouds change? Why do stars shine? What's on the moon? Can we go up ... In 2005, with the successful launch of China Shenzhou VI manned spacecraft, it traveled in space and returned to Earth smoothly.

How proud Nie Haisheng and Uncle Fei Longjun are! They travel in space and win glory for their country! This incident has greatly enhanced the ambition of the people of China and strengthened my confidence: I must become an astronaut, travel in space and fly my beautiful dream.

If I were an astronaut, I would fly to space and stay there, and set up a space camp belonging to us in China, so that more people in China can see the wonders of space.

I am a pupil now, but I firmly believe that as long as I study hard, I will be able to realize my ideal in the future.

Plug in the wings of science and travel in space.

I hope to be a pilot. I want to be a space pilot. It feels good to fly the space shuttle in the universe! It feels good to finish the task! One day, I fell asleep ... suddenly, I heard "Comrade Yu Dexuan please fly at once, Comrade Yu Dexuan please fly at once!" I got on the plane and only listened to "five, four, three, two, one, take off.

""Tiangong-1 and Shenzhou-8 are ready to assemble! "At the command, Tiangong-1 and Shenzhou-8 began to combine" five meters, four meters, three meters, two meters and one meter ",and the combination was successful! "After two days, I suddenly found a short message from the earth: separation; Shenzhou VIII returned to Earth.

After the separation, I reluctantly returned to the earth.

"Zhuang Zhuang, get up" and "Ding Ding Ding-"Dad and the alarm clock woke me up from my dream, and I got up at once.

How I want to be a space pilot!

Science makes life better. About 400 to 500 words are scientific and make life better. From ancient times to the present, there are many peerless celebrities, all of whom are going towards science: Copernicus risked his life to put forward Heliocentrism, Edison discovered tungsten wire and invented electric light through thousands of experiments; From "three people, there must be my teacher" to "scientific development depends on everyone."

"These are all around science.

In ancient times, people were always influenced by theism, did not believe in science, burned incense and worshipped Buddha every day, but in the end they achieved nothing.

Many people worship Buddha, believe in Buddha, and finally eat their own fruit.

But many people believe in science. Although many people were guillotined, they would not give in to death. This spirit is the crystallization of science.

Now, people live a happy life, have all kinds of electrical appliances, make full use of all kinds of resources and apply all kinds of knowledge, which is also the crystallization of science.

Once, I heard such a question: "Are people living well in ancient times or people living well now?" I don't know how the questioner answered. Everyone looks at the question from different angles, but I think science is happiness.

A thousand years ago, people lived a simple life and were riddled with bad karma. Their connection needed to be spread by flying pigeons. It is also a difficult journey from Shanghai to Beijing.

There is no cure for pneumonia, so the whole family can only pray. Over the years, the war has been going on, just for the land, which is pitiful and pathetic.

People nowadays are full and happy.

The medical technology developed at present can cure almost all common diseases in life, and the extended people have more time to expand and enjoy life.

The rapid development of natural science and technology such as biology and chemistry has brought rich and colorful spiritual food to people who were originally curious.

While exploring and inventing, human beings affirmed their self-worth, and while enjoying the benefits brought by science and technology, they also gained happiness.

With such great wisdom, mankind has discovered and created so many "miracles".

The double helix decryption of DNA molecules has benefited the internet of thousands of families, the space shuttle was sent into the universe at cosmic speed for the first time, and the development of cloning technology to help patients with diseases regain their lives was unprecedented in ancient times, and this is the symbol of human science.

Science can make life better because there are a group of good people who make rational use of science and technology.

They apply beautiful science and technology to the construction of social harmony, the enrichment and shaping of human material and spirit, the endless pursuit of truth and the worship of moral quality.

When someone asks you which era you think people are happier, please don't hesitate to tell him now.

Because we live in the cradle of science and enjoy the happiness brought by science and technology.

We also have reason to believe that the rapid development of science and technology will be 100% used to benefit mankind, nature and the world, so that science will bloom with the most beautiful and pure brilliance! Give you a model essay for reference. I hope you can write your composition well. I wish you a step-by-step promotion in your study!

How do astronauts live in space? Astronauts roaming in space get up and wash their faces in the morning. They wipe their faces with a wet towel soaked in lotion, and then comb their hair with a sanitary towel on the brush. After combing, the hair is very clean and the head has been * * *.

As for brushing teeth, American astronauts used chewing special rubber candy instead, and astronauts in the former Soviet Union used wet towels to brush their teeth, and the effect was very good.

Shaving the beard on the ground is easy, but in the case of weightlessness, a special razor must be used. This special electric shaver has a special box for sucking the beard, so that the beard will not float in the cabin.

Bathing is a big problem for astronauts who stay in space for a long time. To this end, scientists designed a special space bathroom and supporting facilities.

The bathroom is a folded closed plastic cloth cover, which is folded and placed on the ceiling of the living room bathroom. There is a bucket-shaped water tank, an electric heater for controlling the water temperature, a nozzle and a pipeline communicating with the water storage tank.

When astronauts take a bath, they should first put on a respirator leading to the outside of the bathroom, and then put down the closed plastic sleeve to prevent water droplets from splashing outward.

Start the electric heater to heat the water in the water tank, turn on the nozzle, and then scrub it with a towel soaked in cleaning solution.

The water vapor in the bathroom flows into the waste water tank below from many micropores on the floor. When the waste water tank is full, it will automatically alarm and send the waste water into the water treatment system.

How do astronauts defecate during space flight? It turns out that there is a bathroom with zipper rubber curtain in the space capsule, the urinal is vacuum, the toilet is connected with a plastic sleeve, the rubber valve is closed quickly after defecation, and urine falls into an airtight rubber bag and enters a plastic container.

Garbage and waste in the cabin are put into containers. When the container is full, they bounce back into space and burn automatically after entering the atmosphere.

Huh? Why is the forest so busy? It turns out that a fruit beauty contest is being held now! Come on! Come on! Come on! Let's go and have a look before it's too late! Player number one appeared.

Ah, if it isn't my good friend Jojo! I saw Jojo dancing on the stage in a red skirt.

Oh, it's a fire dance "Ode to Joy". No wonder she is wearing a skirt that looks cheerful.

Jojo jumped up and down, picked up the microphone on the ground and turned around to end.

"Hello, everyone, I was born in a noble pitaya family named Jojo.

I am not only the most beautiful one in the pitaya family at present, but also brilliant.

Because I contain protein, dietary fiber, vitamin C, vitamin b2 and so on. , refreshing taste, known as the "fairy honey fruit."

"Say that finish, a fire fan shouted:" Come on! Come on! ..... "ah! After the fruit.-Aunt Mangosteen is here.

Noble and elegant, she performed the guzheng solo "Moonlit Night on the Spring River".

After the performance, I gently picked up the receiver and said, "I think everyone knows that I am the mangosteen after the fruit."

I contain citric acid, vitamin b 1, b2, c4, minerals and so on. There are sweet and sour.

Please support me! "Then, grape elder sister came along in a purple skirt. Wow, look, Sister Grape is performing a color-changing show.

She turned it yellow-green; It turned green again; It turned bright red again; It turned purple and black again; And then it turned purple again.

"hello! I was born in a grape family. My name is Grape.

I am rich in glucose, calcium, potassium, phosphorus, iron and so on. , sour with sweet.

Remember, my name is Cao Longzhu! "Say that finish, agate fans sang" We Will Win ".

Other players have also appeared on the stage.

At the end of the competition, Jojo won the most energetic award, Aunt Mangosteen won the best temperament award, and Sister Grape won the best image award.

Hey, friends who didn't go to the beauty pageant don't worry, come and watch the video!
