2. Write a composition about my favorite scientist. My favorite junior high school text is "Remind Happy". We have been used to living in reminders since childhood. As long as the weather is a little trouble, mother says, don't forget to put on more clothes. Just met a friend, my father said, be careful that he is a liar. You achieved a little success, but you didn't laugh. All the people who care about you say together, don't be proud! When you are immersed in joy, you keep saying to yourself, "Don't be too happy, maybe suffering will come soon …" We are used to living with reminders. Visible fear and invisible fear always hover overhead like crows. On the night when the moon is clear, a reminder will come out and say to you: Watch out for the storm. So regardless of the bright moonlight, we made all the preparations before the storm warning in a hurry. When our eyes are wide open, the storm is like a flock of sheep coming home late, and I don't know where to wander. When we really can't stand waiting for disaster, we even maliciously hope that the storm will come early. The storm finally came slowly. We were disappointed to find that most of the preparations were useless. After all, the risks that can be resisted in advance are limited, but the unpredictable disasters in the world are infinite. Overcoming disasters depends more on taking a quick step, and previous nervousness can't help. When the tail of the storm finally went away, we held a messy home. Before we could breathe, a new reminder sounded intelligently, and we began to look forward to the future in fear. There are always disasters in life. In fact, most people have learned to be calm about disasters, but we have not learned to be happy between disasters. We pay too much attention to the awareness of suffering and ignore the reminder of happiness. Please pay attention to happiness from now on! Does happiness also need to be reminded? Think of falling ... think of slippery roads ... think of being cheated ... remember honor and disgrace ... The sages reminded us 100 1 times, but did not remind us of happiness. Maybe they think that happiness can't run away without reminding. Maybe they think you will cherish good things instead of exhorting them. Maybe they value blood and fire too much and think happiness is not worth mentioning. They always stand on dangerous cliffs and tell us how to escape from the suffering that has not yet come. But what is the time after avoiding pain? That is happiness! Learn to enjoy happiness and be reminded when happiness comes. People can naturally learn the pleasure of the senses, but people can't naturally master the rhythm of happiness. The pleasure of the soul and the comfort of the organs are like twin brothers, sometimes interdependent and sometimes diametrically opposed. Happiness is the vibration of the mind. It needs constant training, just like an ear that can only listen to music. In short, happiness is a moment without pain. It doesn't appear as often as we thought. People often just pick up the golden mane on the ground and say, I've seen it before, after the happy golden carriage has sailed away. People like to recall the specimens of happiness, but ignore the moment when happiness is covered with dew and emits fragrance. At that time, we were often in a hurry, looking back and thinking about what we were busy with. Some people predict typhoons, locusts, plagues and earthquakes. No one predicts happiness. In fact, happiness, like everything else in the world, has its signs. Happiness is often hazy, it will bring us moderate rain. Don't always hope for vigorous happiness, it just comes quietly. Don't try to turn up the tap, or your happiness will soon be lost. But you need to use a peaceful heart to quietly understand the true meaning of happiness. Happiness is mostly simple. It won't flash red light at high altitude like a signal flare. It is wrapped in its natural coat, warmly wrapping us. Happiness doesn't like noise and glitz, and often comes in gloom. A cake in poverty, a look in distress, a rough touch from my father, a warm note from my girlfriend … all these are happiness that thousands of dollars can't buy. Like a ruby on an old silk, it is more and more dazzling in desolation. Happiness sometimes plays jokes on us and comes in disguise. Opportunity, friendship, success, reunion ... they are all similar to happiness, but they are not the same as happiness. Happiness will borrow their dresses, wave by wave, get closer, lift the veil and realize that it has a steel core. Happiness is sometimes short-lived, and it will not cover the sky like suffering. If the suffering and happiness of life are divided at the two ends of the scale, the suffering is huge, and happiness may be just a small stone. But the pointer must be tilted to the side of happiness, because there is gold of life there. Happiness has a trapezoidal cross-section, which can be expanded or reduced, depending on whether you cherish it or not. We should be alert to happiness and enjoy every minute when it comes. According to the research of scientists, the result of intentional attention is much better than that of unintentional attention. When spring comes, we should say to ourselves, it's spring! My heart will be green. When we are happy, we should say to ourselves, please remember that happiness will accompany us for a long time at this moment. Then we will be happier! Therefore, in the harvest season, don't think about the possible disaster year, we still have a long winter to think about. We will dance and sing with our friends.
3. How to write my favorite scientist's 500-word composition?
When I was very young, I was lying alone under the night sky. The black night sky is decorated with lights and looks very beautiful. Looking at the night sky, I had a dream when I was a child. I wanted to see what the sky was like.
When I was in primary school, I met an astronomer-Zhang Heng.
Zhang Heng (78- 139) was born in Xi, Nanyang (now stonebridge, Nanyang County, Henan Province). He was a great astronomer in the Eastern Han Dynasty and made an indelible contribution to the development of astronomy in China. In mathematics, geography, painting and literature, Zhang Heng also showed extraordinary talent and extensive knowledge.
Zhang Heng is one of the representatives of Huntian theory in the middle of Eastern Han Dynasty. He pointed out that the moon itself does not shine, and moonlight is actually a reflection of the sun's light; He also correctly explained the cause of the solar eclipse and realized the infinity of the universe and the relationship between the speed of planetary motion and the distance from the earth.
Zhang Heng observed and recorded 2,500 stars, created the world's first leaky ball that can accurately perform astronomical phenomena, the first instrument to test earthquakes-the waiting wind seismograph, and also made a South Locomotive, an automatic drum car, a wooden bird flying to Wan Li and so on.
In order to commemorate Zhang Heng's achievements, people named the crater on the back of the moon as "Zhang Heng Crater" and the asteroid 1802 as "Zhang Heng Asteroid".
Guo Moruo, a famous writer and historian in China in the 20th century, commented on Zhang Heng: "Such an all-round development figure is rare in world history, and it has been admirable for thousands of years."
Although I don't quite understand why, I am also curious about Zhang Heng. I like watching the stars, the night sky and Zhang Heng.
Since I learned that article, I count the stars every night and sleep late into the night every day.
I was naive at the beginning, but now I think it is not so naive.
I like the composition of scientists. In the long river of history, there are many outstanding figures, such as Zhang Heng, Dante, Copernicus, Napoleon, Edison, Einstein ... Among them, I like Edison best, because Edison invented and created many things for people and brought a lot of convenience to people's lives.
When Edison was young, his mother got an acute illness and needed an operation at once. Going too far to the hospital will delay the illness, so the doctor decided to have the operation at their home.
But there was no electric light at that time, and the indoor light was too dim for surgery. Little Edison used his quick wits, made several big mirrors, adjusted the angle to the light, reflected the light to the temporary operating table, and the operating table suddenly lit up.
The doctor successfully completed the operation and Edison's mother was saved. It can be seen from this little incident that Edison was very clever at a young age.
Edison loved chemistry and physics when he was young, so his mother helped him build a small laboratory at home. From then on, he fell in love with experiments, did many dangerous experiments that would help him in the future, and finally won more than 1000 invention patents. The electric light he invented brought light to all mankind, and was praised as a "public hero" by Americans and recognized as the "king of invention" by the whole world.
I want to learn from Edison and become a pillar of the country when I grow up.
5. How to write a 500-word composition of your favorite scientist? There are many outstanding scientists in the long history.
Some people died in the experiment; Some are immersed in science; Some people persist in their research even after the experiment fails. But my favorite scientist is Edison.
Edison liked inventing since he was a child and was curious about many things. He kept researching and experimenting until he understood the truth. On a snowy night, Edison's mother was ill, and his father called a doctor at once. After examining his mother, the doctor said that she had acute appendicitis and had to be operated on immediately. But there was only one oil lamp at that time, and the light of the oil lamp was very dark. If she is not careful, she will open the wrong knife.
Edison's father was as anxious as a cat on hot bricks. Edison suddenly thought of something. He took out all the oil lamps in the house, put a mirror behind the oil lamps, and turned on the lights, so that the doctor could finish the operation smoothly. It can be seen that Edison was very clever from an early age! One day when he grew up, Edison was working in the laboratory. He handed his assistant a glass bulb without a lampholder and said, "Measure its volume."
The assistant finished the light bulb and began to calculate. After a while, Edison asked, "What is the volume?" But the assistant did not answer him. Edison turned around and found his assistant leaning on the table, holding a soft ruler and calculating carefully.
Edison went to the assistant, took the light bulb in his hand, filled it with water, and poured it into a container. He said to his assistant, "This is the volume of water." Genius is one percent inspiration and ninety-nine percent perspiration.
Now Edison has won more than 2000 invention awards. Edison was so clever because he worked hard and pursued tirelessly. We should learn this spirit.
6. My ideal scientist (composition) 400 words means how I like science, not my ideal, which is the first flower in spring; Ideal is the first burning sun in summer; Ideal is the first fruit of autumn; Ideal is the first snowflake in winter; Ideal is an oasis in the desert; Ideal is the clarion call of life. The ideal of mountain stream is the sea, the ideal of prisoner is the blue sky, and the ideal of tree is the earth. Things are still like this, let alone people. Throughout ancient and modern times, Chinese and foreign countries, whoever becomes a big enterprise will have no lofty ideals! Yes! Without ideals, a person's life is like losing his compass and direction in the desert. Without ideals, a person is like a bird without wings, which can never fly. Without ideals, a person can never shine like the sun! I've learned that only those who are enriched by their ideals will be full of love for life, will find fruitful autumn, will raise the sails of life, will exert their intelligence and make contributions to mankind. But where is my ideal? I have stretched out my hands to ask heaven, and I have meditated. Until today, I have the answer-my ideal is to be a doctor, wear a white coat, lend a helping hand to patients when they need it most, give them hope and confidence to overcome diseases, complete the sacred mission of "angels in white" and compete with diseases. In my opinion, their cause is great and noble. They are selfless and fearless. It's a long story, there are other reasons why I want to be a doctor ... In April and May of 2003, the SARS epidemic swept through Beijing, and the atmosphere of terror enveloped Beijing. Suspected medical records kept appearing, which made people panic. At this moment, the soldiers in white are fighting day and night in this battlefield without smoke. There used to be such a hospital-Xiaotangshan Hospital, the front line of anti-SARS, and such a touching scene happened. The battle began in isolation at the front, and everyone let him rest. He always said, "I've been on the first line for so long." With certain experience, you can perform your duties better, change people and increase the source of infection. Do I have to work for a while? " The good doctor hasn't contacted his family for months, so he buried his thoughts about his family deeply in his heart and devoted himself to his work. Finally, he was infected with SARS, because it was discovered too late, and the family reached a critical juncture. But when the doctor interviewed the reporter in the quarantine area, he firmly said, "Please take me." Solve the SARS vaccine as soon as possible, so that more patients can leave the hospital and go home for reunion as soon as possible. "The doctor's selfless dedication deeply touched me and everyone, and we suffered for his death. He was only 36 when he died, and life was so short for him. I can't help but whisper in my heart, "Good doctor, please go! "I will try my best to realize my wish.
I am eager to be a scientist. Everyone's desires are different. Some people are eager to be a glorious people's teacher when they grow up; Some people are eager to be a doctor when they grow up. Some people are eager to be the police to protect their country when they grow up ... and I am eager to be a scientist when I grow up, to invent many things that are beneficial to mankind, to benefit mankind and to promote social development.
Whenever I see my mother busy doing housework at home, I want to invent a multifunctional robot. This robot will be designed with several buttons of different colors. If you press the blue button, it can help you cook and wash dishes. If your floor is dirty, just press the red button and the robot will become an automatic vacuum cleaner to clean your floor. All you have to do is press the red button again, and the automatic vacuum cleaner will look like a robot again. If you want to watch TV, just press the black button, and the robot's stomach will immediately become a small TV, so wherever you go, as long as there is a robot, there is a TV to watch! And the special light from this TV can protect your eyes, no matter how long you watch TV, it won't hurt your eyes. If you are going to be late for school or work, press the pink button and the robot will become a pair of magic shoes. If you wear it, you can get to school or work as quickly as an arrow, and you can set the time. For example, if you want to reach your destination within 10 minutes, the robot will measure the distance between your current position and your destination through the satellite positioning system, and then automatically adjust the speed to ensure that you reach your destination accurately. From now on, you don't have to worry about being late anymore! Do you really want to have the multifunctional robot I invented right away?
Whenever I see floods and earthquakes, countless houses are washed away and collapsed, and countless people are homeless and displaced. I just want to invent a house: when the flood comes, press the water storage button and the water can be stored. You don't have to worry that water can't be stored. The storage container has super compression capacity. If it can't be stored, the storage tank is equipped with an automatic amplification device, which will automatically start, no matter how much water, it can be filled. Moreover, water can be reused, and it can be used to generate electricity and irrigate crops in summer! When the earthquake comes, the take-off device will start automatically, and the house will fly high into the air to avoid the earthquake disaster.
Although this is only a wish in my heart, maybe this wish is still far away from me, but I will never give up and never stop for the wish in my heart, and never back down will pursue it to create a bright future of his own-to become a scientist!
