In ordinary daily life, everyone will inevitably come into contact with composition. Writing a composition can exercise our habit of being alone, calm our mind and think about our future direction. So have you ever studied composition? The following is my 300-word 10 excellent fourth-grade composition. Everyone is welcome to learn from them, and I hope it will help you.

Last National Day, my father bought me a balloon. I blew on the balloon and threw it up, but it floated down. I asked dad, why can't balloons fly to the sky? Dad said, "Let's do an interesting experiment. You will understand after doing the experiment. "

Dad told me to clean a bottle, cut off some waste battery skins and toothpaste skins with scissors and put them in the bottle. Then he brought some hydrochloric acid for cleaning the toilet and slowly poured it into the bottle. Interestingly, the toothpaste skin and battery skin in the bottle will emit many bubbles when they encounter hydrochloric acid. Dad asked me to put the deflated "balloon" on the bottle mouth. The gas in the bottle kept going into the balloon, and the deflated balloon expanded again. Tie up the balloon, throw it up, and the balloon will fly into the sky.

I asked my father, "Why did the balloon fly into the sky this time?" Dad pointed to the bubbling bottle and said, "Hydrochloric acid contains hydrogen. When it meets zinc in battery skin and toothpaste skin, a chemical reaction will occur and hydrogen will be released. Hydrogen is lighter than air, and the balloon is full of hydrogen, so it flies to the sky. "

I jumped up happily: "I see, I see, I see why balloons can fly into the sky."

Excellent composition in grade four 300 words 2 My campus is really beautiful! In spring, everything is revived, birds are singing and flowers are fragrant; In summer, the sun is like fire and the heat wave is rolling; Autumn, sweet-scented osmanthus fragrance; In winter, the wind is biting.

Spring, spring back to the earth, adds a different kind of scenery to the campus. Spring is a vibrant season. Colorful wildflowers in the flower beds, emerald grass, and the French phoenix tree in our school, the green color is really comfortable, and the spring breeze blows slowly, which makes us warm for a long time.

Summer is also very hot, which is the students' favorite season. They can play games on the playground, and summer is still girls' favorite season! In summer, they wear beautiful flowered skirts.

Autumn is the season when fruits are plentiful and fresh fruits are fragrant. Second, I like sweet-scented osmanthus, which has a charming fragrance. It has four small petals and a small stamen, just like the color of corn. It's beautiful. Such petals are like a shy little girl wearing a beige skirt, so I like this fragrant campus by painting!

Winter is a different kind of scenery. Although the weather is very cold, we like it. I want to praise it in one sentence: flowers and plants cover the quilt. The white campus at this time is really beautiful!

I will never forget the winter, spring, autumn and summer of my alma mater!

Today is a fine day. My mother, uncle and aunt went swimming in the sea together. We went to the first bathing beach by bus. We changed our swimsuits and went to the seaside. I got into the life buoy. My uncle pushed me into the deep sea, and I was scared to call for help. I had no choice but to push me back. I must rest in a shallow place first.

After a few minutes' rest, I went to the sea again. I tried to swim by myself with the help of a lifebuoy, but somehow I couldn't swim because my hands and feet were not coordinated. My uncle came to help me again, but I was still scared. I screamed and drank a few mouthfuls. The water in the sea is really salty! It made me rinse my mouth several times.

I sat in a big swimming ring and floated in the water, while I looked up at the sky. It's very late, and the stars in the sky are flashing, as if to say to me, "Don't lose heart, you must learn to swim." You are the best. Come on! " I suddenly felt extremely warm in my heart, as if a warm current was flowing gently through my heart. Although this may be just my guess, I really appreciate the power of encouragement and trust.

It was already dark, and we reluctantly left the vast sea. In the car, I made up my mind that I must learn to swim this summer vacation!

During the summer vacation, my parents took me to travel to Hong Kong by plane, which was my first time to fly.

At the airport, we got the boarding pass, passed the security check and border check, and entered the waiting room. I'm excited and looking forward to it: what's it like to get on the plane? What's it like to fly to the sky to see the earth?

After boarding the plane, the plane began to move. It runs slowly first, then accelerates and makes a "rumbling" sound. My heart is pounding and I'm very nervous. Suddenly, the plane rushed to the end of the runway and flew into the sky. As the plane flew higher and higher, I felt a "buzzing" sound in my ears, and I couldn't hear anything clearly, and it hurt, so I chewed gum hard and the pain was better. Out of curiosity, I looked out of the window and saw that the houses and trees on the ground were getting smaller and smaller, as small as ants, the road was like a belt, and the villages and fields were like colorful puzzles. But the plane is still flying upwards. It has passed through the clouds and flew into the clouds.

Suddenly, a fragrance got into my nose. Oh, dinner! The stewardess handed me an airplane meal. Wow! It's so rich. There are noodles, bread, juice, strawberry jam and butter.

Shortly after dinner, the plane landed safely.

I have a classmate. She has short hair like me. She wears round glasses. When she smiles, her eyes are like two crescent moons. She has a small mouth. She speaks very fast. She is very thin.

My classmate's skeleton is big and hard, and hitting people really hurts. When I play with her after class, she always smiles at me. From time to time, she put her hand into her clothes and hit people with her sleeves. Although she only hit people with her sleeves, it also hurt. Her eyes smile like a crescent moon. When I see them, I always think her eyes can talk. You can't see your eyes when you laugh, just two crescent moons.

My classmate has a good temper and won't get angry. With her, there are always endless topics. Sometimes she will go to the playground with some other students and sit down in a small circle. She started talking and chatting. She can also sing a short song, which makes everyone laugh.

In class, she doesn't talk to others, but sits in her own position. Her study is also good. She is also very kind to others. She doesn't swear or fight. She works very hard, too. When she was in the laboratory, she saw that she was doing the experiment seriously. When other students don't bring books, she will lend them to him. There are always extra books in her desk. If someone doesn't bring them, she will borrow them. She is kind and not stingy at all, which makes people like her very much.

I am very happy to have such a classmate.

I felt cold after getting up this morning. When I opened the window, I saw it was raining, but it was the rain we had been waiting for for for a long time! It is precisely because of its delay that many students have sore throats. The wheat planted by the farmer's uncle is too thirsty to stand. My sister is also very happy to hear the rain, because she can play her little umbrella.

After breakfast, my mother sent me to the door to take a bus. When I got on the bus, I saw a layer of water on the window, so I touched it curiously. I am surprised that I can draw on the window glass in rainy days! I wrote and drew on it with my fingers, and I arrived at the station unconsciously.

After I got off the bus, I didn't wear my hat properly, and big drops of rain ran down my cheeks, feeling cold and cold. When crossing the road, I saw colorful umbrellas walking on the road like beautiful flowers. I looked up at the sky, the sky was covered with dark clouds, and the intermittent rain was like dark clouds crying. By the way, rain is their child, and they are reluctant to leave their arms. Although I am wet, I still want to say to the dark clouds, "Your children have come to earth to do good deeds. You should bless them! " "

Then I remembered that it was time for art class. I reluctantly bid farewell to this lovely rain and ran to the classroom.

My extracurricular life is rich and interesting. I play games, play in the East, read books and visit parks in my spare time ... These things bring me a lot of happiness, but I like playing games best-the eagle catches chickens.

One sunny afternoon, my friends and I played with eagles and chickens in the open space downstairs of my house.

The game begins. A child becomes an eagle first, a child becomes a hen, and other children become baby chicks. The eagle stared at the chicken fiercely. The eagle swooped to the left and right; The hen opened her arms and blocked them for a while. Suddenly, the eagle turned in a big circle, bypassed the hen and pounced on the last chicken. When the hen saw it, she felt that something was wrong and hesitated. The eagle seized the opportunity and rushed over. Scared the chicken to scream "Mom". In this way, the last chicken was caught.

The game was over and we had a good time. This is my rich and interesting after-school life.

There are many kinds of love that accompany us all the time. Severe criticism is a kind of love; Warm words are a kind of love; Caring greetings are a kind of love; Kind eyes are also a kind of love.

Around us, there is such a group of people who silently pay love for us every day. They are-police uncles. They can be seen at the traffic police guard post at the gate of our school at any time. In spring, they wake up earlier than everything else; In summer, they work in the scorching sun; In autumn, when the weather turns cold, I also see them standing in the street; In winter, the cold wind seems to have withered everything, but it still can't blow away their busy figure.

I remember once on my way to school, the weather suddenly changed, and the strong wind came at me with bean-sized raindrops. A classmate and I are going to cross the road with an umbrella against the wind and rain. We just looked down at the road and didn't see a car galloping towards us.

"Look out!" Suddenly a big hand stretched out from behind and pulled us back to safety. "Look! How dangerous that is! Be careful next time! " It turned out that the police uncle helped us. Then he stopped the car and escorted us across the street. Looking at my uncle's back, I can't help but feel a warm current in my heart.

Love is everywhere around us, and it is with these people who pay silently that our life will be so beautiful and full!

Yesterday, it was Xiaoming 10' s birthday. Grandma gave him two cloth toys, a big lion and a small rabbit. Xiao Ming was so happy that he fell asleep holding them. He dreamed that he came to a big forest-the big lion and the little rabbit also came to celebrate his birthday.

The big lion goes to the cow to get milk, and the little rabbit goes to the wild fruit to make jam. The big lion and the little rabbit prepared the materials and began to make cakes together. When the cake was almost finished, a sly fox stole it while they were not looking.

The big lion and the little rabbit have to do it for Xiaoming again. This time, they were very careful and did it more seriously and carefully. Finally, the little rabbit made a box for the cake, and the big lion wrapped the cake beautifully with a ribbon. Xiaoming's birthday present is ready. Xiaoming was very happy when he saw the birthday cake. He gave the cake to his friends, including the big lion and the little rabbit. While eating the cake, my friends kept praising the big lion and the little rabbit, some even hugged each other, and some … Suddenly, Xiao Ming woke up with a smile. It was a dream. He put the big lion and the little rabbit in the most conspicuous place in the room, because they are the best birthday gifts that Xiao Ming received.

There are many excellent people around me, and my favorite is my brother Li Jiayi.

Li Jiayi is a student in Class 3, Grade 5, Lotus Primary School, and a "celebrity" in our school!

He is tall and thin with a handsome face. Eyes are very small, especially divine, always shining with wisdom. His nose is very sensitive and he can always smell all kinds of smells. We often laugh at him as a "dog" nose. He also has a lovely mouth, always witty and very cute.

Although Li Jiayi is thin, he has a big appetite. He likes food and is willing to study it. Scrambled eggs with spicy tendons, pig's trotters with sour soup and Zhajiang Noodles ... are all his favorites. He is also a small chef and always likes to show off on holidays.

Li Jiayi is lively and confident, and plays basketball very well. He can make 10 three-pointers every time he plays basketball. When a goal is scored, it always causes the audience to scream and cheer. Li Jiayi can calm down and be good at writing as well as sports. Li Jiayi's compositions are always displayed by teachers as model essays. Every time I read brother Li Jiayi's article, I always think of a word-duplicity. I hope I can write a beautiful work like Li Jiayi one day.

This is the Li Jiayi I know. I hope he can always maintain the excellent quality of self-confidence.
