Writing idea: You can write a detailed description of the process of making a small plane, with a clear center and smooth and coherent sentences.

Text:

I like those homemade small planes very much, so I call them "bamboo dragonflies" in the sky. In the past, we always stood by and watched the children with planes playing happily, but it never occurred to us that we could make our own helicopter by ourselves.

This afternoon, our fifth-grade classmates came to Haishu District Youth Palace for social practice. Some classes do pottery, some classes have safety classes, and some classes do flowers ... our class actually makes small planes! I'm so surprised, I can't wait to do it at once, and then go to the test flight!

Sitting in our seats, the teacher gave each of us a wooden stick, a thin bamboo pole, a pencil, a ruler, a thread and so on. "First of all, measure three centimeters and four centimeters of sticks at the head and tail respectively, and mark them with a pencil; Then put a dot on the center of the bamboo stick-this is the first step. Remember to use the centimeter side when measuring with a ruler, not the side marked' feet'! " The teacher said loudly.

The students listened carefully, so they finished this step at once, and the classroom began to be a little restless.

"Listen carefully, this step is more difficult, just do it without listening!" When the teacher saw that we had finished, he talked about the next step "We're going to use thread, turn left three times and turn right three times, so as to fix the bamboo stick on the batten. Align the center of the bamboo stick with the mark of three centimeters, and then tie it with thread! "

Now I'm in a hurry. Pinch the box with your thumb and forefinger, and the bamboo stick is disobedient, that is, the center point is not aligned with the mark. It took a lot of effort to make it loose. Finally, the bamboo stick in my hand resigned to fate and stopped obediently. It was much easier, and soon I fixed the cross and tied a fast knot. Looking at the students scratching their heads around, I can't help feeling a little proud.

Then the teacher asked us to tie ropes at both ends of the bamboo stick, and then pull it to four centimeters for binding. I looked at the curved bamboo sticks and irregular crossbows in my hands and sighed in my heart. Because I pulled down the ropes on both sides with different strength, one side was tighter than the other, resulting in the "left-handed" consequence of loose left and tight right.

Then you have to glue a thin piece of paper to the frame. I was still immersed in the last failure and decadence, absently smeared glue all over my hands, and unconsciously stuck the paper upside down. By the time I found out, it was too late. With luck, I looked around, hoping that a classmate would make the same mistake as me, but there was no one.

I had to correct my mistake, simply install the nose and tail backwards, and then install the propeller and rubber band. My helicopter is finished. I thought: since we can't let it come, let it be beautiful! So I solemnly wrote down the three characters "Mayflower" and signed it below.

Finally, the exciting test flight. Everyone was eager to try, and the teacher jumped out like a spring without saying a word. I dawdled out with the plane and silently followed the happy crowd.

Ah, they started flying. Boys compete in groups of three and five to see who can fly high, but they are always overshadowed by "ragged scavengers" who are physically disabled and determined. W's c9 19 is also good, and it is "leading the way" in various small competitions, but for scavengers, it can only be candidly admit defeat.

The dark horse of this competition is H's "Super Invincible" plane. Like a cannon, it surpassed c9 19 to become the runner-up at the last minute. In addition, X's The Strongest King, Z's Flying and M's Space all add luster to this competition.

In contrast, girls' activities are much more elegant. Although we are not as handy as boys, we are also interesting everywhere and have breakthroughs from time to time. You see L's plane has reached a new high and received envious eyes. Y's plane is like a big crab, bullying the weak and fearing the hard, but it always refuses to fly. The plane of C is high and low, but it can draw a beautiful arc every time. ...

My heart itched, but I still tugged at the plane in my hand for fear of making a fool of myself and making people laugh. Finally, I couldn't resist the temptation. I fiddled with the wing carefully, turned the propeller dozens of times and gently pushed it up. My little Mayflower took off slowly. I was very excited, but it trembled in the wind again, suddenly fell down and dived to the ground.

I made several test flights, but may flower didn't live up to expectations at all. He didn't fly until he got underground. I was so angry that I wanted to change its name to "groundhog" several times. I am really discouraged. Did I just waste an afternoon? With a glimmer of hope, I went to the teacher to fix it.

"This can't? You see, turning clockwise and turning counterclockwise will only fly to the ground. " The teacher turned to me and said, "All right." The teacher released his hand.

It's flying, my Mayflower! It's turning, my Mayflower! Fly over six floors, my Mayflower! I am running around happily, tired of running, looking up at the Mayflower, flying so high and so far under the flawless blue sky in Ming Che! Oh, the "bamboo dragonfly" in the sky-my Mayflower …
