Last spring, the sky was incredibly clear, the grass was green and the flowers were in full bloom.
Our family also went to the ferry to fly kites. After a while, everyone's kite flew, but only my kite could not fly, I had to find my father to ask for help, I did not expect my father but mercilessly said: "their own things to do, do not come across things always rely on others, will develop bad habits."
After an hour, I still can't figure it out, people around me are pointing at me, and pointing at me sarcastically, "Look at her, she has been here for a long time, and she doesn't see her kite flying into the sky." When I heard that, my heart was like biting a rotten pear, always bad taste.
There was a middle-aged man beside me, with a girl, and I guessed that she didn't know how to fly a kite, and it wasn't what I expected. The middle-aged man patiently taught her, I put my ear close to listen, only to hear her say, "hands should be placed in this place."
My eyes widened and I mimicked it myself, "Oh, so that's it." Then the middle-aged man said, "Run," and the girl and I ran together, and the kite was rising slowly, and I was so happy, and finally, the middle-aged man tugged on the line and said, "This is how it should be!" My kite flew, and I tugged on the line, bouncing around, and each of those people who had just satirized me froze.
I came to my father's eyes, and he laughed heartily, and said, "If you want to do something, and you can't do it yourself, you should be modest and ask for advice from others, and learn from others, so that you can make progress!" I finally learned to fly a kite, and the birds were jumping happily in the trees, cheering for my success.
2. Why kites can fly up to the sky essay 700Spring is coming, the wind and the sun is warm, the green grass is like grass, the blue sky is often flying all kinds of kites, there are red, there are green, there are human zigzag, there are flying bird-like, colorful, very eye-catching.
When you look up at this one of the beautiful flying objects, do you think of such a question: how do they fly to the sky? To answer this question, let's do a simple little experiment! Take a strip of thin, soft paper about 20 centimeters long and 3 centimeters wide, stick one end of the paper to your lower lip, and then blow through your mouth. At this point, you will find the paper floating upwards.
When you stop blowing, it hangs down again. According to fluid dynamics, when the flow rate of a fluid like air increases, the pressure near the fluid decreases.
Similarly, when you blow with your mouth, the gas flow rate above the paper increases, so that the pressure at the top decreases, and the pressure of the air at the bottom is relatively large, so it holds the paper up. Therefore, the kite to fly to the sky first have two conditions: one is the relative flow of gas, so that the kite above and below the formation of pressure difference; the second is the kite to make the body light surface.
The kite relies on the fluid "wind" to fly into the sky. The first of these conditions is created when the spring breeze blows.
At this point, the head of the kite is facing the wind, and under the constraints of the towline, when viewed from the side of the kite, it forms an acute angle with the horizontal line that opens forward. Under the influence of this acute angle, the airflow in the lower part of the kite becomes denser, and the upper part becomes thinner, so the pressure difference is formed between the upper and lower parts of the kite.
In addition, the weather turns warm in spring, the ground heat rises, increasing the upward force of the kite, so as long as there is a little wind, the kite will easily jump up to the sky. This is the main reason why people fly kites in spring.
From the kite force analysis, downward there is the kite's own gravity and the pull of the traction line, while the upward force must be greater than the former. Therefore, kites are usually made of thin paper or thin plastic paper to reduce gravity.
Some kites are large and increase in weight, but since its force area also increases, the upward torque increases accordingly and does not affect the flight of the kite. When a kite takes off from the ground, it first needs a larger starting torque and also requires a larger wind speed.
Therefore, the site for flying a kite should be open, with no obstacles blocking the wind. Generally the wind is strong on the river surface, so there are often kites flying over the river bank.
Sometimes the wind on the ground is small, it is necessary to hold the kite against the wind to help run for a while, in order to increase the relative speed of the airflow and the kite to increase the uplift force. Once the kite takes off, the kite will be "good wind with the force, send me to the sky", rocking up, flying higher and higher.
At this point, as long as a little shake the line, the kite can spread the wings of the blue sky. China has a long history of flying kites.
As early as in the Han Dynasty, there is a good story of Liu Bang, the founder of Han Gaozu, who took a kite to the sky. Nowadays, the development of kites is more and more advanced.
The kites are as small as the palm of your hand, and as long as more than a hundred meters, and there are people who string hundreds of kites into a long dragon, which is particularly spectacular. Every year at the International Kite Festival, there are even more varieties of kites.
But no matter how the pattern changes, the kite is due to the above principles and fly up to the sky.
3. Spring Kite Flying Descriptive Scenery Writing EssayA Sunday morning, windy and sunny, spring is full of the earth. Fruit trees blossomed, willows sprouted, and from a distance it looked like a green mist, and like a big sister's beautiful hair braid. Trees, flowers and grasses are competing to be the first to offer their fragrance and beauty to Mother Earth. The view is so beautiful!
On the soccer field not far from the school, there are several children flying kites. There are so many kites in the blue sky! That is a crane, that is a centipede, that is a parrot, that is a harrier eagle ...... all kinds of, all in the sky up and down soaring, very beautiful.
In the distance, three or two children are excited, fully concentrated on their favorite kites, they pull the kite line, kite a moment high, a moment low, like in the dance. In a short time, the kite flew into the mid-air. It seemed to say proudly, "Look, I fly the highest!" Next to it, two children seemed to be tired of running, a *** sitting on the ground, watching the kite fly freely.
Nearby, a child is happily flying a "dragonfly". You see, his right hand holding the line, left hand holding the spool, smiling at his kite. "The big dragonfly flapped its wings and blinked its big red eyes, jumping upwards. Before long, the kite caught up with the Butterfly, surpassed the Harrier Hawk, and ducked into the clouds. When Little DouDou, who didn't go to school, saw it, she was so happy that she jumped up three feet high, and kept shouting: "Oh, it's flying! Fly up, 'dragonfly' disappeared, 'dragonfly' disappeared, brother is great, brother is great!" At this time, an airplane flew, "dragonfly" than the plane to fly higher.
I saw, the heart is also itchy, to find their "butterfly", ran out of the door, and the guys put up.
It's easy to see the flowers, but it's hard to embroider them. "The butterfly was swaying like a drunkard. I shook the line, but the kite was spinning around like an ant on a hot pan. I was so anxious that I ran as fast as I could, but it was no use. What to do? I thought, "I'll ask someone else to help me!" So I ran to the owner of the Dragonfly and asked him, "How can I fly the kite as high as the Dragonfly?" He looked at me and then at me. He looked at me and then at the kite, and said, "It has to do with the style of the kite and the air current in the air, and the kite should be flown into the wind, so as long as you know the direction of the air current, you can fly it high." I listened and nodded. By this time, it was very windy on the soccer field, so I shook the line a few times, and the kite flew up with its head swinging. "Let go of the line, let go of the line ......," he said. So I let go of the line, but I couldn't pull it out for a moment. My friend got impatient and took the spool in my hand, he held the spool in his left hand, one end toward the kite, the spool "yi yi yi yi" screamed. After flying the kite, I thought: "I didn't realize that flying a kite also requires skills.
4. good essay on the shape of kites.cnThe weather has finally cleared up. Today the sun is shining and it is a good day for kite flying. We and Mr. Chen came to Riverside Plaza with smiles on our faces and happily prepared to fly kites.
The Riverside Plaza was bustling with activity! There are many brightly colored kites, there are black bat kites, there are beautiful mermaid kites, there are colorful airplane kites ...... I brought a lovely joyful kite. I started to fly the kite with my grandma, but the kite was so disobedient that it only flew in the middle of the air and then slowly drifted down. Grandma and I were sweating profusely. Then my dad came and I was so happy that he could help me fly the kite. I took the kite and kept running forward, the wind came, I sent it upward with force, Dad was responsible for pulling the line while running backward, so that the kite flew up to the blue sky, balanced and soaring, it didn't take long to fly, the kite fell down to the ground, we didn't get discouraged, but continued to fly. Dad was getting happier and happier. I said happily to my dad, "Haha! Our kite finally flew into the blue sky! The kite was so beautiful in the sky! But the sun was shining so brightly that I couldn't open my eyes and couldn't tell which kite I was flying. Suddenly, our kite was in danger, because dad was flying too high, the line almost hit the line of another kite, "Dad, be careful, be careful! Don't hit it!" I shouted eagerly. Luckily, I didn't hit it. "Hey," I sighed with relief. After about five or six minutes of flying, our kite fell from the sky. I ran to catch it. The kite was so hard to fly, but my dad was so good at it!
Time flies so fast! Two hours passed without realizing it, and finally, we took a few pictures with Mr. Chen, and then reluctantly returned to the composition hall.
5. Write kite flying essayToday, the sun shines brightly, the breeze spreads the fragrance of flowers to every corner of the school, continuous rainy, hard to look forward to a sunny day, the students are talking again: last week, the teacher told each of us to bring a kite to school, today so good weather, can go to fly a kite how good it is. Sure enough, in the first class, the teacher announced, "We're going to fly kites this afternoon." "Oh!" The students cheered.
It was hard to get through to the afternoon, the students all brought their kites to the classroom, what a kite party! There are lively and lovely little goldfish, there is a light little parachute, there is a brilliant rainbow, there is a fair and law-abiding Bao Gong ...... is really a variety of forms, each show their style.
We came to the playground, three or two to form a group began to fly kites. A boy and I chose an Ultraman kite ready to fly. He first used the red scarf to try the wind direction, and then raised the kite to stand against the wind, I slowly let go of the line while backing up, almost left him five or six meters when I stood still. "Let go", he sent the kite into the sky with force, I hurriedly pulled the line and ran, letting go of the line as I ran, "Come on, let go of the line!" He yelled. I saw the kite slowly rise up, but suddenly, a horizontal wind blew, and the kite fell down from the air. Alas, it came out badly, but never mind, keep trying. This time, we had the experience and started to fly when the wind was a little bit lower. This time, the kite flew smoothly, I slowly let go of the line while pulling and pulling the line, the kite flew higher and higher, and the line on the ball of string was almost finished, I stopped letting go of the line and held the ball of string with one hand, while pulling and pulling the line with the other hand, so as to keep the kite in the air. When I looked around, my classmates also put their kites into the sky very soon, and all kinds of kites showed their heroic appearance in the sky: "butterflies" and "goldfish" danced beautifully; "airplanes" swooped down at one time, and then relaxed at another. Butterflies and goldfish danced beautifully; airplanes swooped and glided smoothly; and our "Ultraman" was staring at a "big-eyed monster" as if it was about to have a duel....... laughter The whole playground was filled with laughter. "Back to the classroom!" We reluctantly left the playground, the students are not yet finished, and agreed to have time to go back to flying kites
6. to kite as the topic of the essay: why the kite can fly to the skyFirst, the relative flow of gas, so that the kite up and down the formation of the pressure difference; the second is that the kite should be made to be a light body surface.
