I really like bamboo dragonfly. In my heart, every bamboo dragonfly seems to be a dream. When it rotates gently, it will fly in the sky. Its graceful posture and streamlined figure always make me extrapolate and make me feel happy in a dreamy world.
However, I have never bought a bamboo dragonfly, not that I don't want to buy it, but that I have never seen it. Sometimes walking on the busy street, you can't find the figure of bamboo dragonfly anyway, and then looking at the empty sky, there will be an empty loss. One day, my brother came back from other places and called my name. I ran over happily. My brother said he had something for me, and then he took out a bamboo dragonfly from his bag. It's blue and beautiful. He asked me if I liked it, and I shouted, "I like it very much. I've wanted one for a long time ~ "My brother told me that he bought me this Zhi Zhu immediately after his first week's salary.

Composition 2: "I can make bamboo dragonfly" 1500 words I can make bamboo dragonfly.
Three, two, yin and phlegm seven
Today is a special day. I heard that I will attend the "Science and Technology Activities" this morning. The students are very excited and can't wait to go to the Children's Palace at once. We got on the bus at about 8: 30 and soon arrived at the Children's Palace.
The teacher helped us to divide into groups first, and took half the boys and half the girls to two classrooms respectively. I am looking forward to it. I don't know what I am going to do today. We came to the door of the classroom and saw a bamboo dragonfly painted on the sign. We are all very excited.
A male teacher came into the classroom when the bell rang. He told us the history of bamboo dragonfly, a toy invented by the ancients, which has been passed down from 1500 years ago to the present. Finally, it's time to make bamboo dragonflies. First, the teacher introduced the materials for making bamboo dragonflies: pencil, ruler, double-sided tape, a disposable chopstick, two small bamboo pieces with thick left and thin right, and a pyramid-shaped pad. Then use PPT to tell us the making process of bamboo dragonfly. I listened carefully to the teacher's explanation. I thought, is it that simple? I picked up the materials and started to do it. First, grind a thick small bamboo into a slope with a grinding board, but I didn't expect to see the color in the first step. No matter how hard it is, it can't reach the standard required by the teacher. I was a little anxious, so the teacher came over and showed me and told me to be patient. There is something wrong with my technology. I corrected it in time, and in a short time, I ground the small bamboo pieces, then drew a center point for the small wooden block and made a hole the size of disposable chopsticks. I used double-sided tape to stick the pyramid-shaped bottom with small bamboo chips on a small board, and finally stuffed disposable chopsticks into the hole, and the bamboo dragonfly was finished. The seemingly simple bamboo dragonfly took me a whole class.
Today's scientific and technological activities are really rewarding. I learned to be a bamboo dragonfly, and I also learned to be careful and patient in everything.
I can make bamboo dragonflies.
3-2 meters
Everyone has seen the anime Doraemon. Remember Doraemon and Nobita's magic weapon-flying machine, also known as bamboo dragonfly? Today, all the students in our class came to the Youth Activity Center with great interest to learn how to make bamboo dragonflies.
The teacher first introduced us to the history and origin of bamboo dragonfly, then focused on the production process, and then gave us wings, reinforcing blocks, washers, a disposable chopsticks and other tools. I started with confidence: first, draw a diagonal line on the reinforcement block, and the intersection of the two diagonal lines is the center of the reinforcement block. Please ask the teacher to help me make a hole in the middle. Then, I carefully ground the wing with a stone mill, and soon I ground the wing to the radian required by the teacher. Then start the assembly: first stick the gasket on the reinforcing block with double-sided tape, and then stick the wing on the gasket, remember to expose the hole of the reinforcing block. Finally, the round disposable chopsticks are inserted into the central hole of the reinforcing block. So the bamboo dragonfly is ready ~
I can't wait to release the bamboo dragonfly in the yard. When my hand rubs, the rotating wings push the air downward, and the air also gives the bamboo dragonfly an upward reaction lift. At this time, as soon as my hand was released, it flew into the sky. Watching bamboo dragonflies flying in the air, I seem to see Doraemon give me a thumbs up.
This science and technology class is really interesting. It not only enriches our knowledge, but also improves our practical ability. Looking forward to the next science and technology class.
I can tie a great knot.

Today, the teacher took us to the Youth Activity Center to participate in scientific and technological activities-learning to tie wonderful knots.
In the morning, we were all very excited, looking forward to the teacher's early announcement of going to the youth activity center. After a long time, ah ~ the teacher finally came, only to hear the teacher say, "Put your schoolbag back, come out in line, and don't forget to take something ~" At this time, everyone rushed out of the classroom. When we arrived at the Youth Activity Center, the teacher took us to the classroom, where we learned to tie wonderful knots. First, the teacher introduced us to the origin of the wonderful knot, and then the teacher explained the knotting steps of the wonderful knot. After the initial introduction, each teacher gave a colorful braided rope, so let's follow the teacher step by step. I began to hold the rope carefully and follow the teacher. The first few knots were still very unskilled, and I was afraid that the rope would be loose. But when the rope was woven halfway, I seemed to find the trick of knitting, and my skills became more and more skilled. Just then a teacher passed by and looked at my work.
Colored ropes are as beautiful as rainbows when woven. Looking at the wonderful rope I knitted, I can't help feeling happy. I know that only through my hardworking hands can I create a better life. This scientific and technological activity is so meaningful.
Composition 3: How to Make Bamboo Dragonfly The 500-word bamboo dragonfly is an ancient toy in China. Its shape is T-shaped, and its stripes are like propellers.

The first article: bamboo dragonfly, 100, Xin
I made a bamboo dragonfly this evening.
The stick of bamboo dragonfly is made of two toothpicks stuck together. The spiral corners are cut with paper and then fixed together with clay. Finally insert the stick. I didn't play well at first, but I finally succeeded after several turns ~ playing with my own bamboo dragonfly was so beautiful that I didn't want to mention it ~
I hope the bamboo dragonfly will take me to Xinjiang to pick grapes, Mongolia to drink milk tea, Qingdao to pick shells, Hainan to pick coconuts, and finally take me for a walk on the high moon ~
Playing with your own bamboo dragonfly is much more fun than playing with other bamboo dragonflies ~

So I went to the balcony to see if I could fly. The first flight was not good, the second flight was only a little, and the third bamboo dragonfly finally flew.
I was particularly excited, but it didn't fly very high and fell down. However, it also flew.
Chapter III: Bamboo Dragonfly, 100, Xu Yuxiang.
After dinner in the evening, my mother and I began to do the manual homework assigned by the math teacher.
I first found a piece of hard paper, some straws and a stapler. My mother first drew the dragonfly wings on hard paper, then carefully cut them out and inserted them into the straw. But the paper was a little thick, so my mother processed it again and fixed it with a stapler. But the paper was so hard that the wings were broken several times or even broken. I found a piece of soft paper for my mother, but the paper was too soft for the plane to fly and failed. For the third time, my mother still made dragonfly wings out of cardboard and wrapped the two sides of the dragonfly wings with tape. It finally succeeded, and the bamboo dragonfly can finally fly.
This handicraft is really fun. I hope the teacher can arrange more manual homework.
Chapter IV: Bamboo Dragonfly, 100, Song Jiayang.
Today, my father and I made two bamboo dragonflies together. To make a bamboo dragonfly, you should first prepare a plastic straw, then fold a rectangular piece of blue paper in half, draw wings, cut them off with scissors, insert the bottom of the wings into the straw after opening, then fix them with staples to ensure that the wings will not fall off the straw, and finally flatten them, and the bamboo dragonfly is ready.
After the bamboo dragonfly was finished, I put the straw of the bamboo dragonfly on two fingertips and rubbed it hard, and the bamboo dragonfly magically flew. I think this bamboo dragonfly is really fun.

One of them didn't fly very well, and he still couldn't do it once, so he made the second one. The second one flies more stably. The second thing was done by my father.
Dad pointed out the first question, and I listened carefully. The first problem is the wings.
Unbalanced, smaller wings. Turn slowly at the same time, turn slowly.
I can't fly well too fast.
If I have to make another one, I will do it well.

Composition 7: "Bamboo Dragonfly" 500 words Author: Wang Xiaoming
Producer: home video
Duration: 3 minutes
Type: feature film
Confessions of the author:
With the popularity of DV, movies are gradually pulled down from the altar. In recent years, a large number of "DV movies" have emerged in both film-related colleges and non-governmental organizations.
The mysterious art of film suddenly appeared in front of me in an approachable manner. Like many children, I have loved watching movies since I was a child.
Shooting the truth:
This DV movie, planned and filmed by senior high school students, lasts for 35 minutes. It tells the story of an ordinary girl, Xiaoxi, who was admitted to her favorite major for her dream after graduating from high school, but had to face her boyfriend's study in a different place. In the lonely and busy life, girls' feelings and beliefs depend on bamboo dragonflies. I happened to meet the ocean with the same ideal as myself, wandering between reality and ideal, and finally breaking through the shackles, facing everything calmly and realizing my own story.
As a high school student, my partners and I have broken through all the pressures and overcome many unexpected and unexpected difficulties. After ten weekends of shooting and three weeks of post-production, the film was finally completed, the picture was clear and beautiful, and the actors performed naturally and sincerely. Teamwork is very enjoyable.
If you have ever had a sincere relationship in high school and a unique loss in college, I believe this short film will touch you!
My language:
Many people always talk about what they want to do, their expectations and ideals ... but the cruel reality makes them impossible to achieve.
Actually, just do it if you want!

Me and my bamboo dragonfly
Last time I went to the park, I bought a bamboo dragonfly and liked it very much. Every time I come home from school, I always fly with it for a while, and it feels really good. However, once my sister Jia Jia came to my house to play and took a fancy to bamboo dragonflies. She also wants to play. Because of the strong wind at that time, she accidentally flew the bamboo dragonfly to the billboard on the roof. We can't take it off. I am so disappointed. Sister Hua Mu promised to buy me another bamboo dragonfly, but she never bought it. I've been sorry for this for two weeks ~
On Sunday afternoon, my father said that he would take me to visit Sijing Park again. Mom listened and said, "Yo, just go over there and see if there are any bamboo dragonflies. I'll buy you one." After listening to this, I was very happy and set off happily with my parents.
Today is May Day, and the park is crowded with people, which is very lively. I went to various toy stalls to find the bamboo dragonfly I wanted, but I never bought it. Later, my father bought me a kind of "bamboo dragonfly" similar to a flying saucer. This kind of bamboo dragonfly is easier to play and flies higher and farther than the original one. I'm glad to let it fly. It flies to the crowd for a while and then behind the rockery. I am having a swell time. Suddenly, my bamboo dragonfly was out of my control and flew to that big tree. I couldn't get down. I'm worried that it's hanging on the branch all the time. Dad used many methods, such as throwing it with a mineral water bottle and poking it with a long branch, to no avail. I'm almost desperate. What can I do? A gust of wind blew, and my bamboo dragonfly actually got out of the leaves and fell down. Alas ~ a false alarm.
When I get home, I want more. I continued to take out my recovery bamboo dragonfly and play with it. Just as I was having fun, the tragedy happened again. My bamboo dragonfly flew to the billboard again. This time, it is hopeless. Because the billboard is too high, none of us can get up or down. I thought to myself: Maybe this bamboo dragonfly is looking for the last bamboo dragonfly as a companion. Otherwise, it will lie there alone, without company. I don't regret thinking so. However, I still hope for a miracle, and I hope that one day those two bamboo dragonflies will fly to me again.
