In daily study, work and life, many people write compositions, which can be divided into narrative, expository, practical and argumentative according to different genres. I believe writing a composition is a headache for many people. The following are seven compositions of the fourth grade of Underwater World compiled by me for reference only. Welcome to reading.

The underwater world is a paradise for fish.

There are clusters of flowers and plants of different lengths and postures on the seabed. They danced at the bottom of the sea, which was very beautiful. Seaweed also has various colors, including red, green and blue ... There are groups of big crabs next to seaweed, swaggering around with big pliers, feeling that the whole underwater world belongs to them.

There is a turtle on the crab. The turtle has a dark green shell. When there is danger, the tortoise can retract its head into its shell to protect itself. There is an octopus on the turtle's left. Octopus shakes its eight feet and shuttles through this vast ocean.

On the turtle's right is a bubble fish. As soon as the bubble fish inhales, it becomes a ball, covered with thorns. When it spits out another breath, it doesn't know where it is. Bubble fish also spit out many bubbles of different sizes.

What a lively underwater world!

Underwater world level 4 composition 2 look! How beautiful the underwater world is! The blue sea floor sparkles. What happened? Oh! It turned out that it was the birthday of the sea princess and invited sea animals to the party. Every day, the bottom of the sea shines.

On this day, the father of the sea princess "Fox" will help the princess choose a husband, but after several years, he still hasn't found it. On the 20th birthday of the princess, I met a prince by chance. Her name was Alex. As soon as I saw her, I fell in love with this handsome prince.

They met in secret, and the prince finally couldn't stand such a meeting. He proposed to his father, and after their efforts, he finally persuaded his parents. On a beautiful day, Princess Ocean and Prince Alex held a grand wedding and invited all kinds of underwater animals to participate.

Two years later, a mermaid was born in the ocean, which is the most beautiful mermaid under the sea. They named the little mermaid "Kewen", and their family lived a happy life from then on.

Underwater world is not the first time for me to visit underwater world, but only one trip to underwater world has brought me endless fun.

As soon as I entered the underwater world, I saw a group of people wearing big jackets swimming from there. After a while, a zebra-striped fish swam over. I put my hand on the glass cover and the fish swam to me excitedly. Maybe they think they have food, or maybe they really want to make friends with me?

I left the fish and unconsciously came to the Penguin Pavilion. Look, a penguin with a white belly and black skin. Walking around, not to mention how cute they are. Seeing this, I thought: shouldn't penguins be in the North Pole? Why are they here?

I was full of questions along the way!

In the underwater world, you can not only play but also learn knowledge. There are still many mysteries in the underwater world waiting for us to solve.

The beautiful underwater world is a mysterious world, and it is also my dream place. In Friday's club activity class, I made a picture of the underwater world with space mud.

I prepared colorful space mud, a drawing board and a tool knife in advance. Production has begun. First, the blue space mud is used as the background, then the green space mud is used to make aquatic plants, and a line is drawn on the aquatic plants with a tool knife. Then, the light blue space mud is used to make the dolphin's body, and the dark blue space mud is used to make a small hand under the dolphin's body. Finally, the picture is decorated with small fish and shrimp, and a turtle is drawn.

In this way, the animals are ready, and I feel a little empty. I also made some corals on it. Soon, a beautiful map of the underwater world was formed. Look! Small fish happily spit bubbles; Dolphins jump happily, dancing like a little girl; Octopus bared its teeth like a soldier fighting; The crab waved the pliers in his hand like a commander in chief; At this time, a turtle trying to sleep passed the upper reaches of the crab head and fell asleep on the stone. It's so stupid that people can't stop laughing. The ripples of swimming make the aquatic plants sway gently. Their color is green and beautiful.

Appreciating my own works, I have a sense of success in my heart. If there is an opportunity in the future, I will definitely go to the underwater world to have a look.

Every time I mention the underwater world, the deepest impression is the underwater world in Beijing, where there are many kinds of fish, which makes people feel immersive.

This summer vacation, my parents took me on a trip to Beijing. We have just been to the Great Wall, and now we are going to the underwater world. Wait for the tour guide's uncle to buy the ticket first, and then we will queue up and enter in turn.

My parents and I walked in happily. "ah!" I said excitedly, "How beautiful!" This is my first time to the underwater world. I saw sharks, but they were not terrible. They are all small sharks, not as tall as me, so cute! I also took photos with the little sharks. I also saw orange starfish, simple and heavy tortoise, lobster with long beard, small and lovely clown fish, silver arowana, colorful butterfly fish, broad and sturdy rice fish, gentle and beautiful mermaid … However, mermaid is not true. It was decorated by several aunts. They played with all kinds of fish in the transparent glass pool, and we watched along the cross-harbour tunnel with other tourists. The cross-harbour tunnel is very special. The long conveyor belt makes us feel that when we walk into the Crystal Palace, all kinds of fish in the sea are nearby, and we can reach out and catch them.

Out of the underwater world, I am still full of interest. My mother and I went to buy a lot of things in the underwater world. There are crocodiles made of plastic, butterfly fish made of magnets and dolphins made of crystal ... I chose a lot of things, kept some as souvenirs for myself, and made toys for my sister and brother, and my father paid for them. Then we went out. Some people haven't come out yet I waited for a long time, but I couldn't get out. Underwater world is really interesting!

In the far north of the Pacific Ocean, there is a quiet and harmonious beach, and all the creatures on the seabed live in peace. One day, the underwater world was broken by a quarrel. ...

I saw the crab owner of krusty krab restaurant holding a handful of money and proudly saying, "Haha! I am a monopoly, I am better than you! My hand is like a pair of pliers, and only brother crayfish can make friends with me. "

Squidward Tentacles, the cashier at krusty krab, was not satisfied after hearing this. He said unconvinced: "Cut! What's the big deal about money? You are a miser! If you want to compete, I have eight. How about it? "

Spongebob, the chef of Crab King, never quarrels about anything. His face is always full of smiles, but this time, he shouted angrily, "you are not as good as me." I am flexible, I can be calm! "

Patrick, who is eating hamburgers in krusty krab, spoke. He said, "Stop it! Can you compare with me? My five broken hands can still grow. What about you? Don't argue, this is my strongest. "

Elder Eel, another customer of Krusty krab, said indifferently: "Young people are young people, and my technology is no match at all! If you make me angry, I'll turn him into dust! "

"My crab boss is strong, I am the strongest!" "I can do many things at the same time in Squidward Tentacles, I am stronger!" "How do you want to squeeze me will do. My Spongebob can't even blink! " "Even if you cut off my big star's hands, I don't care, because they will grow back!" "You don't even recognize my eel predecessors, or I'll electrocute you! "

……

While they were arguing fiercely, Brother Shark walked into krusty krab restaurant with Donawhale in his arms. Knowing the cause of the quarrel, they sighed and said, "You all have your own advantages, just like: the crab boss and the eel elder can defend their country and are admirable heroes;" Spongebob and Patrick can be acrobats, making people smile; Squidward Tentacles has so many hands that he can be a dancer and a national idol! In fact, we all have our own advantages, but why should we quarrel here instead of giving full play to our respective advantages? "

Everyone suddenly realized!

I find that my diary is always much later than my life because of my laziness. I went to the aquarium on Thursday. This is really an interesting place.

I am surprised that there are so many colors of fish in the water, and each one is so pure. Looking at their gorgeous appearance, they swim so happily in the water, just like a princess. There are lovely starfish. Someone can touch them personally in the touch pool. I actually looked for it for a long time before I found it. They are actually similar to rocks on the seabed, but they are like a five-pointed star. There is a sign next to it that says: Please don't bite starfish. Haha, these poor little guys.

What excites me most is the dolphin show. These dolphins are really smart. They can sing, clap their hands and dance. In the clear water, they churned and jumped carefree, competing to show themselves. The life of dolphins is so happy.

In fact, writing these things is no longer in the mood at that time, but I know it was a happy time. Let's go and have a look when you are free.
