The name of this seaplane is "Zhi Qin Si". I named it because people must be intelligent, thoughtful and diligent in order to create advanced technology and bring convenience to mankind.
"Smart Qin Si" is a multifunctional seaplane. When I find that there is drought in any area, I can immediately land the plane on the sea surface, draw water, then move the seawater into the purification box, purify the seawater into purified water, and then transport the purified water to the arid area. It can also become a submarine, dive to the bottom of the sea to clean up garbage, and reduce the harm of marine garbage to human beings and the earth. By the way, if the ship suddenly runs out of oil during the voyage, you can refuel the ship immediately.
What do you think of this seaplane after listening to my introduction?
2. Unforgettable airplane contest composition 400 words in grade four Today, we are going to hold a "paper airplane flying contest".
I took out a brand-new rectangular white paper from my schoolbag. I first folded the top half of the rectangular paper into a "double triangle", then folded the other two corners of the "double triangle" towards the center line, then folded the whole paper in half, and finally folded two wings.
I look at this paper plane. Its head is sharp, its body is big, and its wings are slightly upturned. I seem to be a pilot, flying the plane I designed in space!
The game began, and the teacher said, "Whoever lands the plane last will win!" "
"I thought, haha, my" circle number "is definitely no problem!
So, I boldly stepped onto the podium. Unexpectedly, the other plane is very big. I feel guilty. However, since I have the courage to stand on the podium, I have to have the courage to compete. I can't help thinking so. My left foot is in front and my right foot is in the back, in a lunge posture. Aim your left hand at the top front, pick up the plane with your right hand, and lean back slightly. Only the teacher shouted, "Ready, let's go." I immediately kicked my leg and waist and threw the plane out with all my strength. My plane made two big circles in the air and slowly returned to me, while my opponent's plane crashed directly into the ground.
"Ha ha, I won!
"I cheered. The students in the audience responded with warm applause.
The paper airplane flight contest is over, and I feel the joy of victory.
My favorite sentence in the fourth grade composition is related to paper airplanes. It's sunny on Wednesday, September 10th. Every year, September 6th is Teachers' Day. Teachers are the greatest people in the world. I think, because they teach us how to write and read. Most importantly, they teach us how to be a real man. They are friendly to everyone and don't want anyone to fall behind others. They always get along well with students. They are our best friends. When students are in trouble, they can help them in time. I will be a teacher when I grow up. .
I am a coca-cola bottle. Like other brothers, my stomach is full of sweet and delicious cola.
I tell you, my other two sworn brothers and I are really the so-called "coke bottle overlords". Because you bought us, you can win clothes, buffet coupons and another bottle of rewards respectively.
Many people want to buy us. As long as someone "eats" a dollar coin into the selling box, one of us will come out of the box, and once the drink in our stomach is finished, it will be discarded. One day, a little boy stuffed eight coins into the box, and seven other brothers and I all rolled out of the box and were taken home by the boy.
It turns out that he has guests at home and wants us to entertain him. Because our coke tastes good, they drank it happily. They said, "This drink is really sweet, delicious, delicious."
After they finished drinking, the boy carried us into the room. He unscrewed our bottle cap first, then put me sideways and cut me in the middle with a plastic knife. Half of my body was thrown into the trash can. He made three small holes in the rest of my body, put his wings and tail in the holes, and then painted me with gouache. I suddenly became a space shuttle, and several other brothers, polished by the boy's dexterous hands and powered, became a long rocket, and then.
The next day, we were taken to the little boy's school. The school is holding a handicraft conference. There are dozens of big tables on the stage, filled with all kinds of handmade works. We were arranged at table a. Oh! It turned out that the young master brought us to the handicraft meeting.
There, we made many friends: wind chimes made of canned food, pandas made of clay, giraffes made of ceramics, flying saucers and aliens made of paper, dolphins made of plasticine ... At this time, the selection meeting began, and finally, we won the first prize. I am very happy because some of our values have really been applied.
The rule of the paper airplane competition is that you must fly the folded paper airplane into the designated circle, not too close or too far.
This is a great challenge for the players. The first player in our class is Li Yunqian. I saw his right foot bent, his left foot straight, posing and preparing to fly his plane to the designated place.
When the referee gave the order, Li Yunqian and his competitors flew the plane at the same time. Unfortunately, Li Yunqian's plane was stopped before it reached its destination. In the second scene, Li Yunqian's plane flew into the designated point, and our class cheered.
The second player was Qian Junyi, and the result was also successful. All five players in our class successfully piloted the plane to the designated point.
Through this activity, I think origami plane is also a science. If the plane is folded heavily, it can't fly. If you fold it gently, it will be easily blown away by the wind. Only by mastering the method of origami plane can a good paper plane be folded. I want to learn more science and master scientific knowledge in the future.
Paper airplane competition This morning, we held a fierce paper airplane competition on the playground. I was in the first group and only heard the teacher say, "Get ready!" "We are all ready for the test flight. The teacher said," Let's go! "We threw the plane out. My plane, like a disobedient bird, ran to the side and "ate". I was so angry that I stamped my foot and went to the "bird" and killed it at once.
We finished the game, and the students in the second and third groups also appeared in black and pink, not to be outdone ... Ishihara flew farthest, just waving his hand, and the plane was like an obedient bird, flying more than 12 meters. Finally, Liu Yancen and Ishihara were selected.
It's a pity that I didn't make it. Now I can only cheer for them. The paper airplane competition is really interesting.
Paper airplane competition Paper airplane is fun, but we can't play it out of control. No, I played paper airplanes with five classmates too much and was caught by the teacher. The teacher decided to let the six of us hold a plane competition. I really don't know if this game is a curse or a blessing. It's the day of the game. Before the game, the sky was overcast, and our inner tension was like a dark cloud in the sky, which accumulated more and more. Paper airplane competition composition 6 Paper airplane competition composition 6.
Usually we are noisy in the queue, but today, the team is quiet and scary, especially our opponents, who look at each other with a straight face and don't know whether they are worried or afraid. On the playground, the teacher announced the rules of the game: "A game decides the outcome, the winner is king, and the loser is kou."
We can't help but get nervous and worry about our reputation in Sun Shan. But then I remembered the philosopher Nietzsche's words: "Heroes must fight."
This sentence gave me encouragement, confidence and completely got rid of my inner fear, so I worked very hard to meet the game. The game started, and after drawing lots, I was the first to vote.
I took out my treasure-"F-22 fighter". I leaned back slightly and tried my best. The plane made a beautiful arc in the air and landed smoothly on the ground. Wow! At least 10 meter! The whole class applauded me. I closed my eyes and thought beautifully, "I am the only champion, let alone the last one!" " "Just when I want to enjoy the joy of victory, I heard more applause. When I opened my eyes, it turned out that Mao Guangpeng's "old passenger plane" flew a few centimeters more than my "F-22 fighter". At this time, I was worried about the plane behind me, afraid that their plane would overtake mine, so I really lost my name in Sunshan.
Fortunately, they didn't play very well and left me a runner-up position. The game is over, but my heart seems to be filled with lead, which is extremely heavy.
Although it feels good before the game, there are more strong ones among the strong! If you practice a few more times before the game, you may win the championship in one fell swoop. Through this competition, I understand a truth: no pains, no gains.
Chapter 4: Interesting Paper Plane Competition This afternoon, our school held a paper plane competition, in which students of Grade One, Grade Two and Grade Three participated. Many students are cheering for us on the playground. Miss Li, the PE teacher, organized our competition. Miss Li asked us to line up in every grade. Everyone flies once and stands at the back of the line, taking turns flying three times. Throw the plane out and see who flies for a long time.
The game has begun. Our students in Class 20 1 Grade 2 flew first. The first classmate's plane flew out in a spin, and the second classmate's plane was very small. Unexpectedly, his plane flew out at once, and then flew in the air for a while before slowly falling to the ground. Everyone applauded and cheered for him ... It was our turn to Class 203, and Betty Wong and I were very nervous. Betty Wong said, "OK, come on!" I threw the plane out with great force. The plane made three turns in the air and finally landed on the ground. Students cheer for me! Betty Wong's plane has a folded triangle on its wing. Her plane flies well. The cheers of her classmates made us less nervous. Then we flew the second and third times, and each time we flew better. My brother and sister in grade one compete with my brother and sister in grade three. We made all kinds of planes, and President Li took photos of us.
This paper airplane competition is really interesting. I will make a better paper plane to participate in the competition in the future! Chapter 5: Paper Plane Competition winter vacation life is a colorful and easy life: you can sleep until you wake up naturally every day; After finishing my homework, I can exercise with my neighbors and friends, and I can also travel with my parents ... I had a good time, and the day when I stacked a plane with my brother was the most impressive. It was a sunny noon, and the warm sunshine shone on us, which suddenly threw the cold for many days outside the cloud nine.
After lunch, my brother suggested a plane race. The competition is to fold several paper planes first, and then have a distance competition to see who folds the plane and flies smoothly and far. I readily agreed, thinking: How difficult can it be to fold a paper plane? This is a piece of cake. So we folded planes to compete, and my folded planes were defeated by my brother one after another, never winning once.
I am extremely depressed. It is really not easy for a seemingly simple paper plane to fly fast and steadily. I went back to my room and was looking for it.
6. Paper Plane Wars Composition [Paper Plane Wars Composition]
On the morning of June 65438+1October 65438+September, 2006, I went to my good friend Xiao Peng's house to play. I wrote a paper airplane war composition, which was written in the fourth grade of primary school. As soon as I walked into Xiao Peng's home, I saw him playing a paper airplane war with another child, Yang Yang. Seeing that they were having a good time, I said, "Can I join in?" "Of course!" The two children said. So, I quickly folded a paper plane and named it "Rocket". The battle began, and the rocket was the first to set off, knocking the shark off the table in Xiao Peng with no effort. Then, Yang Yang's God of War appeared and dived into the rocket at high speed. Seeing that the situation was not good, the rocket quickly flew from the table to the chair 1 meter away. The rocket can't get on the table, and the god of war can't get on the chair. After a stalemate, Ares changed his tactics and tried to rush to the chair. Ares increased his horsepower and rushed over quickly. I didn't expect the God of War to be too inertial and rushed out of the chair. "I won" I shouted happily. In the second set, I didn't expect sharks in Xiao Peng to turn into snails. Although walking slowly, but the defense is very strong, the rocket rushed past first. Unexpectedly, the rocket flew over the snail and fell to the ground. It's the god of war's turn to fight. The god of war played a trick and pretended to be defeated and fled back. The snail followed slowly and reluctantly. God of war made a fool of himself. When there is no way to escape, it goes up to see if it can be transferred to the snail's back and let it turn Gankun around. Unexpectedly, the direction can't be controlled. When it hit the snail's back, the snail saw that the defeat was decided, and both sides were hurt. The horsepower increased and it all fell to the ground. ..... Today, I played very tired, but I had a good time. Pupils' Paper Plane Wars Composition 500-word Composition (/)
7. Small composition exercises in the fifth lesson of the fourth grade of primary school (continued) It is late at night, and the wind is still blowing outside. Looking at the backs of the three German officers, Mrs. Bernold's uneasy heart calmed down a little. She stood up wearily and walked upstairs. "Jacqueline, my good boy, are you asleep?"
Hearing her mother's cry, her daughter Jacqueline got out of bed, walked gently to the stairs and looked down. She answered her mother's question in a gentle voice, "Mom, is that you?" I'm here. The candlestick is well preserved. How's it going? Have the German soldiers left? "
"Let's go, let's go." Mrs. Benod said in a tired voice.
Jacqueline picked up the candlestick from the table and ran down the stairs. When she saw her mother, she threw herself into her arms. "Mom, is our disaster over?" I'm really scared. "Mrs. Benoit hugged her daughter tightly. At this time, her mood fluctuated like a flood, and she was thinking about the future.
Mrs. Benoord sighed deeply, looked at her daughter, and then looked back at her son Jack-he had fallen asleep at his desk.
Mrs. Benod: "What you are doing, children, is wonderful!" " Thank god for getting rid of this disaster. ""Mom, did I do really well? "I was really scared just now, you don't know, my heart is about to jump out," Jacqueline said. "Sister, it doesn't matter, it's all over, isn't it? Don't worry, those damn German officers haven't found out yet! " When he spoke, Jack seemed to remember something. "Mom, I think it's too dangerous to put information in that half candle." "Hmm ~ ~ ~ ~ ~" Mrs. Benod was lost in thought, and she met a thorny problem again.
Finally, the candle went out. At that critical moment, my sister quickly climbed the stairs and hid the metal tube under the bed. The German officer went upstairs as if he had found something, and just found the metal pipe under the bed. My mother followed, exhausted her strength. Finally, she and her sister knocked the German officer to the ground and ran away with the metal pipe.

Lun Ji's voice came from Babiki: "Laura, come to the playground." Luo Ling looked at her watch and muttered, "It's only after four o'clock. I practiced so late yesterday that I was not allowed to sleep more. "
Luo Ling rubbed her eyes and went to the playground. , Dadong, Zuo and Luo Ling waved. Laura Bell ran past, but when she was about one meter away from them, she was blocked by the enchantment set by people.
Then Lun Ji and others rushed over, and Luo Ling said, "Who set this enchantment?" Lun Ji said, "I don't know. I'll call Jiang to unlock the enchantment! " Say and go to the middle of the war. After waiting for ten minutes, Lun Ji took Ginger to Laura Bell.
Luo Ling asked, "What happened over there?" Jiang untied the enchantment and said, "There is no time to explain to you. Come in. " During the war, the girl from hell shouted, "Ginger, come and help me break the spell."
Cingil rushed into the war. Luo Ling also went.
The enchanted boy is a demon. Ginger tried many times, but she couldn't solve it. Ginger said to Laura, "You try, I'm in your way."
Luo Ling nodded, then knelt on the ground, closed her eyes to gather magic, and whispered, "Remove the magic." The hell boy's screams faded away, and Ginger whispered, "You are really something."
Luo Ling smiled shyly. "Babiki" rang, and Winter hurriedly said, "Luo Ling, come here quickly, there is a good show here!" Luo Ling said, "Oh." Winter is ahead, Luo Ling's soul said, and Luo Ling ran to the front.

9. The composition in the second volume of the fourth grade continues to write lesson 17. I especially like dusk. When I set foot on the tree-lined path, I began to imagine traveling through time and space. I stopped at the place full of flowers, lay on the green grass and looked up at the sky, and suddenly felt how beautiful everything was.
I am a quiet person. I want to close my eyes and feel the scenery of the earth. I was thinking, trying to think, when I opened my eyes again, suddenly a bird came into my sight ... At this time, I used a little poem to express my association:
I lay on the green grass,
A bird flew into my window.
I fantasize ...
Oh! You are the legendary flying pigeon,
Please send me a message to a distant place.
Please take away my loneliness.
Please accept my blessing.
Please tell me,
Whether she is happy and healthy.
I pray.
I know that these beautiful scenes are impossible to realize, but I still wait as always. Let me wait here for a while, let me sleep in my fantasy, imagine the taste of reunion, and comfort my soul.
Night, slowly getting stronger and stronger. I really want to wait but I can't, but my heart is still waiting there, waiting for the bird to return. Slowly, my figure disappeared into the darkness.
I'm happy. I've captured happiness. Even in an instant! Even if there is some nothingness!
10. Do you need to write a continuation story for the fourth grade composition? I have lived in a beautiful coastal city-Xiamen since I was a child.
My family lives by the sea. People say that the sea is unpredictable, but in my heart, the sea is like a great man, magnificent. He has a broad mind and a kind side. How was Wu Shen? .
The sea is the most beautiful in the morning. The blue sea is boundless and connected with the blue sky.
When the sun rose, the sun father-in-law just showed his kind face and dyed the sea light red. It's very quiet around, only the sea water gently washes the rocks, just like an old man stroking his baby gently.
The opposite Gulangyu Island is a vivid picture, not to mention how attractive it is to people who used to do morning exercises! At noon, the sun hung all over the sky, and the dazzling light broke the peace of the sea. The sunny sea is sparkling like a layer of gold.
Small waves, small waves chasing small waves, like happy children chasing carefree, let alone how happy they are. Grandpa Hai took out beautiful shells and sent them to the seaside to tease lovely children.
Shanghai seagulls at sea also come to join in the fun. Are they like white flowers? Touch the sea. Hovering on the sea, singing softly.
Occasionally, seagulls dive toward the sea, and just touch the sea and fly again, with a silver fish in their mouth! In the evening, people go home, birds go back to their nests, the sun goes home and the stars come out. After a hard day, Grandpa Sun sank to the bottom of the sea and slept quietly.
The microwave on the sea is very slow, and sometimes there are waves of cool sea breeze, so comfortable and comfortable! Everything fell asleep and the sea was calm again. Only neon lights and advertising lights on the shore are embedded in the sea. Sea level at night. Ah! This is just the sea in my hometown.

I also feel very happy! Today, in the teacher's words, is the harvest season.
When the teacher showed the certificate in the afternoon, he thought that the certificate had nothing to do with me, and it certainly had nothing to do with me. But then came the teacher's sweet voice: Xiao Fuming won the third prize of "Listening and Written Test".

Let me write it again! I have written two compositions this week! I cry, cry ... I cry loudly.
Write after crying ~ Brazilian tortoise My family has a Brazilian tortoise named "Wang Cai", which was given by my grandmother. When I heard this name, I only knew that my grandmother was a money addict. I kept it in a fish tank and put a big stone in it to let it climb up in the sun.
Everyone knows that Brazilian tortoise is also an amphibian. Only the size of an adult's palm.
There is a hexagonal gray-green pattern on the back. There are very hard turtle shells up and down, even if they fall from a height, they will not die.
The turtle has a short neck with wavy lines on it. Two eyes are round, as big as small mung beans, and sparkling eyes are embedded in the middle.
It won't turn. When it flashes, it will make a slight "click" sound. You can't hear it without paying attention. The little turtle likes to eat raw meat, but it only eats lean meat. Every time I throw food into the fish tank, it always sticks out its neck and looks around, and opens its mouth to eat.
The tortoise eats like a snake, swallowing it bit by bit. The book says that the tortoise's eyesight is amazing. To prove whether it is as described in the book, I hung the meat on the water with a thread. The water is only 10 cm deep, but it is invisible.
Although its eyesight is not good, its feeling and hearing are very sensitive. I put the turtle on the ground and clap my hand at the distance of 10 meter, and it will retract its head like lightning, but I have looked everywhere, but I can't see its ears.
When the tortoise crawls, as long as I touch its tail with my hand, it will suddenly shrink all its organs and limbs into a hard shell, which is enough to show how sensitive it feels. When the Brazilian tortoise is energetic, it will crawl back and forth, sometimes it will climb to the stone prepared for it, and then it will climb to the bottom of the tank.
When I was bored, I Doby it and put it on the ground, but it plunged its head into the ground and paddled its feet in one direction. Suddenly, it plunged into the ground, supported by its claws, and it turned over! That's interesting. Brazilian tortoise is so silly and cute! It brings a lot of fun to my life.
When you are in a bad mood, look at it and the unhappy things will disappear.
