The composition of the fourth grade in Underwater World

In normal study, work or life, everyone has the experience of writing, so you are familiar with writing. Writing is an important means to cultivate people's observation, association, imagination, thinking and memory. Then the question comes, how to write an excellent composition? The following are nine compositions of the fourth grade of Underwater World that I collected and sorted out. Welcome to share.

In the far north of the Pacific Ocean, there is a quiet and harmonious beach where 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!

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.

Today is Wednesday, and all the teachers and students in our school take the shuttle bus to the East Lake Marine Animal Museum. We talked and laughed in the car and looked forward to getting to the aquarium early. How time flies! Immediately arrived at the Aquarium, focusing on the construction of tropical rain forest, submarine tunnel, marine life museum, family aquarium ecological museum, specimen museum and popular science education museum. Among them, my favorite is the performance of marine animals. It's interesting to watch the antics of marine animals.

There are two kinds of praise for marine animals. The first one is a beautiful sea lion couple from Tasmania, Africa. They came to Wuhan, not far from Wan Li. They are slim, smart and eager to perform. Together with several seals from the northeast, they settled in Wuhan Sea World. They cooperate closely with each other. Under the careful training of the trainers, they performed wonderful programs for us, such as heading the ball in the air, catching the ball, paddling the surfboard and shaking hands with the coach.

We also watched the big turtle that everyone loved, strolled in the undersea tunnel, and enjoyed the thrilling sharks. Sharks are the representative of fierceness in the ocean. They swim fast, have sharp teeth, a keen sense of smell, developed eyesight, a wide range of eating habits, and sometimes are in danger of hitting people. In the vivid tropical rain forest, colorful freshwater fish in the world are displayed, and ornamental fish from coral reef waters have different shapes, rich body colors, various types, good at hiding, and a primitive and simple natural beauty.

Colorful sea fish get together and think of a beautiful painting.

This morning, my mother took me to buy a ticket to Xiamen Underwater World online. In the afternoon, we came to the underwater world.

There is a huge octopus at the entrance of underwater world, which is the symbol of underwater world in Xiamen. Underwater world is divided into fish house and penguin house.

When we first entered the exhibition hall on the first floor, the first thing we saw was a saw ray. As the name implies, this animal has many thorns on its nose, which looks like a saw. Then I saw a strange marine creature called a hexagonal dinosaur. I call it a dinosaur. In fact, it is not big, about 5 or 6 centimeters, but its head looks like a triceratops. I also saw beautiful jellyfish. They change color according to the light, sometimes red, sometimes green, sometimes yellow, and also blue and other colors. I also saw a seahorse that can swim upright. They seem to have only one fin on their back, but they can move freely in the water by flapping their tails. There are also marine creatures I have never seen, such as paramecium crabs and nurse sharks.

Arriving at the exhibition hall on the second floor, I saw a huge marine skeleton, which turned out to be a sperm whale skeleton specimen. It is the largest and most complete sperm whale skeleton specimen in the world. Later, we saw a sperm whale skin specimen, which was 18.6 meters long and weighed 48 tons. It is reported that the death of this sperm whale may be due to the necrosis of its ninth vertebra. Scientists have made great efforts to produce specimens of dead sperm whales.

Underwater world is really a strange and beautiful place!

The underwater world is full of wonders, and the underwater world is even more strange. Don't believe me, take your time.

1. Anemone and Clownfish

There are many animals on the wonderful seabed that can benefit each other, such as clownfish and anemones. Clownfish are mostly red and white, like a clown. Anemones are not plants, but animals. Every "petal" is covered with toxic cells, which is a devastating weapon!

And cruel, won't hurt clown fish. Clownfish has a "protective film" on its body, and its smell makes anemones mistake it for their own kind. In this way, clownfish help anemones attract other fish, anemones protect clownfish and help each other, which is good for everyone.

Second, the magical dolphin.

There are also some magical animals that can swim and sleep at the same time. This is a dolphin. Dolphins have special brains. When the left hemisphere is awake, the right hemisphere will go to rest. When the right hemisphere is awake, the left hemisphere will rest. This replacement can not only rest but also delay swimming, which really kills two birds with one stone!

Third, the strange flounder

The flounder has strange eyes. Other fish have eyes on both sides of their heads, but they are all on the same side. In fact, it was not like this when I was young. When it was young, it was no different from other fish. With the growth of age, one of its eyes slowly moved to the other side and eventually grew into the same side. Although it is small, even a shark can be scared to death. Because it can secrete a toxic substance, although it is harmless to human body, it can paralyze sharks. People use this substance to make "anti-shark spirit", which has a wide range of uses.

Fourth, the overlord of the ocean-sharks.

The marine life we know best is sharks. Shark is the overlord in the ocean, and almost all fish (except flounder) have become its dish. The fiercest shark in the ocean is the great white shark, which is the largest carnivorous shark; But not all sharks eat meat, and they are all so ferocious. For example, the basking shark, although second only to the whale shark in size, swims slowly, has a gentle personality and won't kill people at will.

Five, the beautiful killer-jellyfish

If sharks are ferocious killers, then jellyfish are beautiful killers. A translucent jellyfish, like a small parachute. The tentacles below are like fluttering ribbons. Don't be fooled by its beautiful appearance, it is a powerful killer! Each tentacle is covered with toxic cells, paralyzing the opponent first, and then killing the opponent with venom. Then feed it into your mouth bit by bit. If you see jellyfish, don't mess with it!

6. Deep sea? ? ? ? fish

In the depths of the sea, there is a glimmer of light. Oh, and this is? ? ? ? Fish. She is a woman. What do we see? ? ? ? Most fish are females. So how do they reproduce? Look at her carefully, there are many small pimples. That's her little husband. The food she eats should also be nutritious for the "little husband" These "little husbands" will die slowly after the breeding period. ? ? ? ? There is a small meat ball on the fish head. When she hides to hunt, she will show small meat balls to attract small fish to "take the bait".

Seven, seahorse father who can "give birth to a baby"

A little seahorse hooked the mouth of another little seahorse, and it was born! Ha ha! It turned out that father seahorse gave birth to a baby seahorse! That's weird. How can a male hippocampus have children? In fact, it was the mother hippocampus that gave birth to the baby hippocampus. She put the eggs in her father's pouch and let him hatch. The posture of the little hippocampus is very interesting. When a baby seahorse is born, it will hook the mouth of the second baby seahorse with its tail, and the second baby seahorse will hook the mouth of the third baby seahorse with its tail … until the last baby seahorse is born!

The wonder of the underwater world can't be seen for a while. Everyone must enrich their knowledge and learn more about those things on the seabed!

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 exhaled another breath, it didn't know where it was sprayed. Bubble fish also spit out many bubbles of different sizes.

What a lively underwater world!

The underwater world has beautiful scenery and many interesting things. This is a paradise for children.

In the exhibition hall, there are many beautiful fish, very beautiful. Some fish are colorful, just like peacocks; Some fish are proud of their fins like the hair of a lion; Some fish have high camouflage skills and lie motionless on the rocks, just like a stone at the bottom of the sea … really like a colorful painting.

The wonderful sea lion and seal show began. The clever sea lion swam to the ball. Suddenly, the heavy body of the sea lion jumped out of the height of nearly three meters and bounced the ball into the sky. There was warm applause from the audience. There are also seals playing drums, and the seals follow the movements of the animal trainer and play a beautiful music, which is very beautiful. I don't think seals lose to sea lions at all. I hope they can have more wonderful performances in the future.

Outside the exhibition hall, there are many beautiful flowers, red, yellow and blue ... just like a colorful ocean. The staff also weaved some grass into the shape of a dragon. These lively dragons seem to say, "welcome to yours, son. I wish you a happy day!" "

Underwater world is really a good place for children to play.

What is the underwater world like? I only read it in books before, but today I finally read it, because we are going to visit the sea world, which is located in the beautiful coastal city of Dalian.

When I came to the aquarium, I was attracted by many marine life, including sharks and turtles. It shocked my eyes. Among these marine life, the most beautiful are jellyfish and fish. "Wow!" I opened my eyes wide. Jellyfish swim here in a showcase full of seawater. They are "running" here, and behind the "running" are colorful "mushroom corals". Their shapes are wonderful. The shape of mushrooms really opened my eyes. In the "fish therapy" area, lovely and beautiful fish swim freely. I put my hand in the fish tank, and the fish rushed up to grab the fish food in my hand. "How comfortable!" I was deeply intoxicated. I also watched a dolphin show and went to the Sea Lion Hall. The dolphin performance was wonderful. The staff threw the ball to the little dolphin. Dolphins are hovering in the water, with balls in their hands. Little dolphin is a master of arithmetic. This is very interesting. Sea lions are more interesting. I put my hand on the glass, and a sea lion rolled playfully in front of me, as if welcoming me.

Through this visit, I not only learned about the beautiful world under the sea, but also saw many fish that I have never seen before, and I also gained a lot of knowledge. What a wonderful underwater world! I was a little nostalgic and forgot to come back!

During the summer vacation, my mother took me to Hangzhou Underwater World. As soon as I came in, I saw many beautiful fish swimming freely in the fish tank. Walking in the cross-harbour tunnel, I saw a big shark upstream of my head. My heart trembled a little, and I felt that the shark was going to eat us.

After crossing the cross-harbour tunnel, we went to the Dolphin Pavilion and watched the wonderful performance of dolphins. Uncle first asked two rabbits to jump in circles, and they jumped flexibly, and then asked the dolphins to kiss the hands of the audience. I put my hand into the railing, and bunny hop got up and kissed me, which made me feel funny and happy.

Then, we also saw stupid clown fish, red butterfly fish, crystal clear fish, lively and lovely tropical fish, which were really varied and colorful! The most striking thing is coral, some like branches, some like willow wicker, with different shapes, big and small, strange and colorful.

Seeing these colorful aquatic animals, I know there are countless mysteries in the world.
