Entering the Ocean Polar World is an artificial tropical rain forest. There are all kinds of tropical rainforest trees here, including many tall banyan trees. I heard the sound of rain and the chirping of birds. We walked forward along the rugged trail. There were many fish tanks next to the tropical rain forest. There were all kinds of fish in them, including all kinds of beautiful tropical fish, catfish... and some more ferocious fish, like food Mermaid, electric eel, small shark, etc. There is also an ammeter in the electric eel's fish tank. The pointer in the ammeter will jump once every few seconds, which means that the electric eel is discharging. We walked to a wooden bridge, and I asked my mother, "What is this bridge for?" My mother said, "Didn't you see the crocodile under the bridge?" I looked under the bridge, ah! There are many ferocious crocodiles under the bridge. They are lying on the rocks, motionless, as if they are sleeping.

Ah! As soon as we entered the hall, we saw a huge white thing swimming in a huge pool, ah! It turned out to be a great white whale! I couldn't help but laugh when I saw the beluga whale. The beluga whale looks so cute. There is a big bulging bump on its white head, just like an old birthday star. When it swims in the water, it keeps raising its head to breathe. , as if greeting us.

Walking through the beluga pool, we arrived at the hall where a polar bear was kept. The polar bear was lying lazily on an iceberg. The polar bear was very big, much bigger than I imagined. Its whole body Covered in a layer of white, thick fur, with a little flash of light from time to time, it looks much more beautiful than a black bear. It lives very comfortably in the cold environment and seems not to be afraid of anyone.

After watching the beluga whale and walrus, we then entered the undersea tunnel. As soon as we entered here, swarms of fish were swimming around and above us, as if we had really entered the sea, or entered the Dragon King's Crystal Palace.

I found that there was an information card a few meters under the glass here, which contained various marine knowledge, some of which contained knowledge of fish types, and some of which contained knowledge of marine plants.

We walked forward slowly. There were some fish I knew, such as small sharks, manta rays... and some groups of fish I couldn’t name. The patterns on their bodies were They are all very beautiful, and they are swimming around in various colors. Suddenly, I saw a diver waving to us in the water. This diver was so powerful that he was not even afraid of the manta rays.

When we exited the undersea tunnel, we saw a large pool that looked like a giant screen. This pool was originally used for the "Mermaid" performance. It's almost ten o'clock now, and we're just in time, the "Mermaid" show is about to begin.

We found a seat and sat down respectively. After waiting for a while, the "Mermaid" performance began. It turns out that the "mermaids" are played by people. I thought they were real "mermaids", but they are also very powerful. They can hold their breath underwater for such a long time, and they dance gracefully in the water with their gauze. They dance like real "mermaids". Even the fish swimming around are dancing with them. It's so beautiful.

We walked and finally came to the place I wanted to see most.

Sea lion performance, the concert is the most amazing thing about the whole performance, and the concert is the funniest thing for me.

In the concert, Xiaoqi will be the drummer; Miyuki will play the gong; Xiaoxue is good at playing the piano; Xiaoai is a famous soprano. The "Song of Sea Lions" began, and with a whistle, the song "Domi Domi Haloxylon, dong dong dong, Dodo Mimi~" began to play. This is a brand new combination. Then, another set of combinations appeared in front of us: "Duomi Duomi Soso Duo, dong dong dang, Duomi Duomi oh oh oh~" The two sets were combined to form a complete sea lion song.

It’s really awesome!

I also watched the Wonderland on Earth - the place where the Queen Mother takes a shower, the big and cute beluga whale, the piranha that can eat a chicken with feathers in 5 seconds and only the skeleton is left, the huge and A scary shark. I also know that there are many types of sharks! For example: the most ferocious sharks are the great white shark, bull shark, and tiger shark; the most primitive shark is the frilled shark, which is about 400 million years old; and the most cunning shark is the cat shark. The largest shark is 25 meters long and weighs 40 tons; the smallest shark is about 15 centimeters long...

The ocean world is so amazing, no wonder it is called the largest ocean world in Asia! Ocean World Fourth Grade Composition 2

Hangzhou Polar Ocean World is one of the largest ocean worlds in China. There are "Polar Kingdom", "Whale Bay", "Penguin Square", " Gold Coast", "Underwater World", etc. The aquarium displays rare polar marine animals from all over the world, including polar bears, beluga whales, walruses, Arctic wolves from the Arctic, penguins from the Antarctic, and Pacific dolphins, American sea lions...

As soon as you enter the park entrance, you feel the slightest chill, and there is a unique cave inside. The first thing that catches the eye is a polar bear dressed in snow-white and cute. It has a pair of round and big eyes, and small ears that do not match its body.

Then I saw the Gold Coast, which is home to all kinds of fish: there are sucker fish that can suck on the glass, scary piranhas, and many fish of different shapes and colors. Fish, I have forgotten its name. After walking through the dazzling fish museum, what appeared in front of us was the whale shark museum. I saw two great white whales, all white and very huge! Although their bodies may seem a bit clumsy, they swim very fast, and their voices are very nice, crisp and bright. The breeders say they are the high-pitched princes in the water.

Because the performance time was coming soon, we went to the underwater theater on the underground floor to watch the "Human Shark *** Dance" performance. The divers rode sharks to the sound of music and spun manta rays in their hands, performing the "Northeast Two-person Spin" in tacit understanding. People and sharks danced a beautiful underwater waltz in the water.

Next, we arrived at Penguin Square. The body of the baby penguin has two colors: black and white, with a white belly and a black back. It waddles when it walks. Do you think the baby penguin walks very slowly? In fact, it swims very fast. It can swim in an instant. disappear before your eyes.

The most interesting thing is that when we passed through the undersea tunnel, many fish swam over our heads, and various fishes swam past us on all sides. The manta ray is the most attractive to me. Its body is huge and flat, its tail is thin and long, and its eyes and mouth are under the abdomen. It looks very honest and honest, and I can't help but touch it with my hands. It felt like I was really in the middle of the ocean floor.

We also went to see the Jellyfish Museum. There are many jellyfish inside, of different sizes, and some will change color. With the addition of human lighting effects, the entire jellyfish museum has become a magical world. The rocket jellyfish is like a burning flame, very beautiful and spectacular. The jellyfish opens and closes again, and it feels like it is changing into various forms at any time!

There is also the king of longevity in the aquarium - the sea turtle. Usually it lies motionless on the rocks in the pool, but when it sees food, it will quickly open its mouth and eat the food. The turtle is a long-lived animal in the ocean, so people regard it as a mascot.

This visit to the underwater world opened my eyes and gained a lot. I look forward to exploring the mysterious ocean world next time. Ocean World Fourth Grade Composition Part 3

This weekend, my mother said she would take me to the Ocean Polar World in Penglai. I was so happy that I jumped three feet high.

We came to Penglai talking and laughing, and what caught our eyes was a dolphin statue, which is said to symbolize an angel. Next, we went to Sea World.

As soon as you enter the gate, you see the four characters "tropical rainforest". I looked around, and there were schools of fish everywhere: piranhas, carp... I ran to the piranha group and said, "Ah, why is the piranha so small?" I looked carefully and found that it has sharp teeth. Even elephants can tear it apart."

We walked to the second floor. I heard that the second floor is a good place to watch performances. At this time, there was a burst of singing, and I quickly ran to the place where the mermaids were performing. I seemed to be a mermaid, performing with them.

After watching the performance, I couldn’t help but admire: “Penglai is so beautiful!” Sea World Fourth Grade Composition 4

Sea World is undoubtedly one of the great buildings. People nowadays want to see it. It’s not easy to get there (except for those who live by the sea). Except on the dining table, it is difficult to see fish living in the sea, but our Ningbo Ocean World is not perfect. I think the ocean world in my mind should be like this:

The theme part of the ocean world is an aquarium The aquarium is full of corals and aquatic plants, just like in the ocean, and the water is naturally authentic sea water. The entire aquarium is divided into two parts, one is an area for eating herbivores or plankton, and the other is an area where carnivorous fish and their food live, where you can actually watch the scene of carnivorous fish hunting. In the middle is a corridor of 20 to 30 meters, with several tables and chairs on both sides of the corridor, where you can rest and watch the fish, eat and watch the fish. There are also signs on the corridors to protect the ocean or introduce fish. Next to the aquarium is a food store where you can buy food. Next to the food store is a prop shop with several wetsuits that allow you to dive in a safe area and observe fish up close. There is also a 3D telescope there, through which you can see the ocean, the formation of fish, and the changes in fish growth. There is also a marine encyclopedia, which records most of the fish. Not far from the aquarium, there is a performance area with wonderful performances by seals and dolphins. Jump through hoops, do arithmetic... Then there is a marine park, which has marine-related game facilities, such as water slides, diving platforms... Of course, you have to change into a swimming suit. It allows children to learn more ocean knowledge while playing, and also allows children to increase their awareness of better protection of oceans and fish.

This is the Ningbo Ocean World I imagined. In order to realize my dream, I must study hard now so that I can build it better and improve it better in the future. Sea World Fourth Grade Composition Part 5

Bang! Bang! The raindrops hit the car window glass, splashing small water splashes. This is a sun rain. It is said that after the sun rain, a rainbow will appear in the sky. The thought of seeing a beautiful rainbow makes me feel very good! Having said that, it was one o'clock in the afternoon on Saturday, August 4th, and our family of three was on the way to the Polar Ocean Park. Along the way, we were full of joy and drove to today's destination-Chengdu Haichang Polar Ocean World.

Because I got lost for a while, it was already four o’clock in the afternoon when I arrived at the aquarium. I heard that it would close at six o’clock. My mother and I ran as soon as we got off the car and went straight to the park. When we bought the tickets, we listened to There were two performances left, so I thought we were pretty lucky. After entering the park, we couldn't wait to go to the Happy Theater to watch the performances. There was a clown performing a funny show, and the audience burst into laughter. After discussing it with my mother, I think we have seen this kind of performance several times before, and considering the time, we decided to go directly to see various animals.

First of all, we came to the Penguin Pavilion. The cool breeze was blowing. The penguins stood on the artificial ice and walked happily. Looking at it, I found a penguin standing alone on the ice cliff, as if there was no one else around. She is combing her feathers, looking very cute. Suddenly, its buttocks tilted up, and a thin stream of water flowed out of its body. It turned out that it was peeing, and the tourists all laughed.

Penguins are my favorite little animals, but polar bears also make me yearn for them. Our second stop was to the polar bear pavilion. There are about three or four polar bears in the museum. They are huge and have different postures: some play with each other; some lazily run to the cave to rest after a while; some seem to be connected with the tourists, showing their big smiles. Bear paws, posing in various poses for photos with us.

Next, we visited the Sea Lion Pavilion, Marine Beast Bay, Walrus Pavilion, and Seal Bay one by one according to the icons. Time passed so fast, and it was soon time to watch the dolphin show. I took my mother with me When I ran to the dolphinarium, I saw people swimming with dolphins in the water, as if they were dancing in the water, which was very beautiful. But I didn’t have time to take a closer look, because there was a more exciting show waiting for me. When we arrived at the large performance hall, after a while, the hall which was empty just now was filled with people, which shows that everyone likes to watch the dolphin show.

The dolphin show was really exciting. The dolphins learned to walk like a penguin, dive, surf, sing a small chorus, and spin a hula hoop. It was so interesting!

Because of my happiness, I felt that time passed too fast. After watching the performance, I hurried to the underwater world. It was beautiful, but we had no time to linger! Because the radio is already informing tourists to leave as soon as possible and the museum will be closed. There is no other way, we can only leave with a little regret! However, lovely polar marine animals, I will come to see you again! Wait for me! Sea World Fourth Grade Composition Part 6

Usually, I often hear my classmates say that Sea World is very fun. I really want to go, but I don’t have time. At noon, I was doing homework at home. My mother called and said that she would take me to visit Sea World. My coke was broken.

Although the weather was very hot, we drove to Sea World with great interest.

As soon as I arrived at the Civic Square, I saw a tall and large blue glass house. It was very beautiful. With the sign of Sea World, it became even more spectacular.

We lined up neatly from the entrance and took the elevator to the fourth floor. As soon as I entered, there were all large and small glass fish tanks. There were many fish in the fish tanks, which made me dazzled. The first thing that caught my eye was the big pencil fish. It looked like a pencil turned sideways, with a pointed head, a thin body, and a gray body, floating in the fish tank. The pearl fish came over and was very eye-catching. It was covered in red and purple and stood up like lollipops in the water. Then the pufferfish came into my sight. It was round, like a ball, and covered with spines to protect itself. Finally, what we saw was the archer fish, which stood upright like a beautiful umbrella, so beautiful.

After going down the stairs, we saw the famous national protected animal-Chinese sturgeon. Its home is so beautiful! There is a waterfall above and a bathhouse below. I really envy its leisurely life.

We are going to the undersea tunnel. As soon as I entered, my feet felt very cool. I saw that there was an air conditioner under my feet. When I looked up, the ceiling and walls were all transparent, and I could see a large group of fish and corals...

When I walked out of the tunnel, I saw a mermaid performance. I was stunned. A diver actually lured out a manta ray and started singing and dancing with it. Although the manta ray has a flat belly, it has a big appetite. The diver gave it a small yellow croaker and it swallowed it in one bite.

We were going downstairs again, and we heard a burst of cheers before we entered the door. I went in and saw that it was a seal performing. The trainer blew a whistle, and the baby seals rolled up obediently and stood at attention. The whole audience was stunned by Little Seal's talent. The baby seals are about to jump high, and they will pass if they jump to the trainer's hand. The little seal jumped hard, as if to say: "Wow, it's so high. Why can't I jump up 10 times?" Finally, the little seal jumped up with all his strength. The whole place burst into laughter. The little seal got the prize from the trainer and got into the water with a "swish" and went swimming.

I walked out of the ocean world reluctantly. At the door, I also got an underwater pearl.

Today, I had so much fun visiting Ocean World! I will definitely come again if I have the chance. Sea World Fourth Grade Composition Chapter 7

Today, my father and I went to Ningbo Sea World.

As soon as we walked in the door, we were attracted by this dreamlike scenery: lifelike artificial flowers, red, white, yellow, all kinds of colorful! This is the "man-made Wu Ge Grotto".

Going up the winding stairs, we came to "Ancient Egypt" and began our journey to the ocean.

There are countless fish here. I looked left and right, and suddenly, my eyes were attracted by a kind of fish called "Fox Fish". It has a pointed mouth, a yellow body, a white head, and black eyes, like wearing sunglasses. The head really looks like a fox’s head!

As we continued walking forward, we saw many rare fish. Such as cute giant salamanders, interesting blades and dangerous agouti... there are all kinds of them. It’s an eye-opener and a feast for the eyes!

At this time, the performance at the Ocean Theater was about to begin, so we immediately rushed to the Ocean Theater to watch the show.

The performance began, and the first one to appear was the little brown walrus. As soon as it came on the stage, it blew the trumpet "beep".

It can do weight loss exercises and roll around on the floor. The most exciting thing is to do sit-ups. I saw it holding its head with both "hands" at right angles to the body to be considered one. It actually did ten in one breath, and the audience immediately applauded like thunder! Finally, it blew a kiss to us. What a cute little walrus!

The next one is the dolphin, it can head the ball, play tennis and lift weights... it is a good athlete!

The last one to come on stage is the beluga whale. Its beautiful "song" is truly a "bird in the water"!
