I am a blue whale writing a composition.

1. I am a blue whale. I need more than 300 words to write a composition. Hello everyone! Long time no see! I am a huge blue whale, weighing over ten tons. I belong to the baleen whale and have no teeth. Usually eat some small fish and shrimp, and you can eat more than 2000 kilograms in one meal!

I am a real mammal. Many people don't know me and think I'm a fish. I was born viviparous, and I had to eat my mother's milk to grow up when I was a child. I breathe with my lungs, and every once in a while I will surface to breathe; One more thing, my ancestors lived on land like cattle and sheep. These three points fully show that I am not a fish.

Our family is divided into two categories, one is toothed whales and the other is baleen whales. The larger baleen whales are blue whales and fin whales, while the larger toothed whales are killer whales and sperm whales. We are distributed in all sea areas of the earth. In recent years, due to human killing and marine environmental pollution, there are less than 50 blue whales left. We have lived on the earth for more than 50 million years. Are we really going extinct like this?

"ah! Help, the Japanese whaling ship is coming! " I ran away when I heard the cry for help. Only my good friend Xiaozhuang is still playing there. Before I could swim to get it back, it was fished away by the big ship. Alas! Poor friend! After a while, a dead whale was thrown back. I swam to have a look. Isn't this Xiaozhuang? How did you die? Later, I learned that the Japanese took it back and killed it, and then peeled it for experiments. We didn't provoke you. Why should we kill Xiaozhuang? In fact, as long as you take a little skin tissue from Xiaozhuang, you can do the experiment. Killing Xiaozhuang is cruel! These fucking Japanese!

As a blue whale, what I want to say is: Humans, don't kill us again. It is extremely rare that we live a life of fear every day. At this rate, we will all be extinct one day! On behalf of all whales, I ask you, we live in harmony, can we have a clean, uneducated home?

2. I am a whale, and I can't copy my composition online.

Give you a

I am a whale, and I am the largest whale in the ocean-the blue whale, also called the razor whale.

When I am happy, I will float on the sea in Shanghai and say hello to the blue sky and white clouds; When I'm upset, I dive to the bottom of the sea and ignore anyone who comes to me. When the weather is clear, I swim to the seaside, emerge from the water, look at the land and mountains from a distance and think: Where did our ancestors come from?

To talk about my ancestors, we have to start from 450 million years ago.

At that time, the ancient bearded fish evolved into amphibians, reptiles, birds and mammals. It was not until 70 million years ago that our ancestors differentiated from mammals.

At that time, our ancestors were still on land, then occupied the ocean and lived in shallow water, and finally adapted to the life of the ocean and evolved into our current whales.

We are so big, we must have a big belly. What should I eat with such a big belly? When I eat shrimp in eat small fish, I first swell up and swallow it with the sea water. Then I shut my mouth, let out the water and only swallowed the food. Why are our shrimps in eat small fish? Because we have no teeth, we can't chew food, so we can only eat shrimps from eat small fish. Although they are small, they are numerous, so we don't worry about going hungry.

Do you know that?/You know what? Do you know that?/You know what? My lung weighs about 1500 kg and can absorb 15000 liters of air. I can stay underwater 18 minutes. When I take a breath, due to excessive pressure, there will be a "fountain" on the sea, which is beautiful! Jet out more than ten meters high, and then spread around, landing on the sea, splashing, looking from a distance, like fireworks in the festival, very beautiful!

I am a whale. I used to be a carefree and happy whale, living in the boundless Pacific Ocean. There are many friends, all kinds of prey I like, and of course, the unique and spectacular scenery under the sea ... alas, it's a pity that this is a thing of the past. Every time I think of the past, I see the scene of "the seas run dry and the rocks crumble" now. That would be extremely heartbreaking. Let's talk about the most fundamental reason first. Humans often throw drink bottles, plastic bags, scraps of paper and other things that are not beneficial to the ocean, thus polluting the ocean. The terrible thing is that those plastics will emit some toxins and smells, which will make marine life infected and die one by one. What's even more frightening is that a whale like me will choke to death once the plastic bag is sucked into the lungs. Such similar accidents have happened more than once. Let's talk about people's absorption of crude oil. People are constantly exploring energy from the ocean, which will of course cause some unnecessary accidents, such as oil spill. On March 1978, the "Amojo-Cadiz" hit the Potsdam Rock Reef near the coast of Brittany, causing serious damage to the environment. 1604500 barrels of crude oil all leaked to the seabed, causing heavy losses to wildlife. There are 20,000 seabirds, 9,000 tons of oysters and millions of animals living on the bottom of the sea, such as starfish and sea urchins. People kill marine animals. People have wiped out all edible marine life: shells, oysters, turtles, sea cucumbers, pike ... those black-hearted vendors even. One of my closest relatives ran aground on the beach with his last breath. He looked at people with pity, hoping that people could save it ashore, but ... but people secretly cut whale meat with knives and prepared to go back and cook it. Dude, I can't describe your behavior. If you don't get rid of your short-sightedness and arrogance, the earth will be destroyed by your hands sooner or later.

4. Composition "I am a blue whale" Hello everyone, I am a blue whale, and I am the largest animal in the world! Although we cetaceans have the word "fish" in their names, we are real mammals.

Our blue whale is the largest of all known animals since ancient times. It is about 30 meters long and weighs between 150 and 200 tons, which is equivalent to the total weight of more than 25 Asian elephants or more than 300 people. Our blue whale's body surface is light blue or mouse gray, with light fine patterns on the back and white spots on the chest, which is very beautiful. Our big tail is wide and flat, and the whole body is streamlined. It looks like a razor, so it is also called "razor whale".

Although we live in the sea, we breathe with our lungs like other mammals. Our lung weighs 1000 kilograms and can hold 1000 liters of air. It is precisely because of such a large lung capacity that we can greatly reduce the number of breaths, and only breathe once every 10~ 15 minutes. When breathing, carbon dioxide and other waste gases in the lungs are discharged from the body through the nostrils, and then fresh air is inhaled.

Because my body is too big, I eat a lot of things every day. My favorite food is shrimp. We can eat more than 2 million krill at a time, and we can eat 4000~8000 kilograms every day! If the food in our stomachs is less than 2000 kilograms, we will feel hungry. Because krill is widely distributed in the North and South Poles, in order to get enough food, we have lived in the polar regions for generations and rarely in tropical waters.

We are all treasures and have high economic value. Our bodies are rich in oil, and our beards, skins, bones, meat and internal organs can all be used as raw materials for industry, light industry and food processing industry. It is precisely because of this that humans have killed us in large numbers, making our family on the verge of extinction, and many of our companions have lost their lives.

Here, I hope that human friends can live in harmony with us and make our earth home full of vitality.

I am a whale, a whale full of longing for life. I love the sea, my family and beautiful scenery. However, my fate has been destroyed again and again.

I was born on a sunny day. I slowly opened my eyes. At first glance, I saw the warm sunshine shining in the water, sparkling, touching and beautiful. I immediately glanced around. "Wow!" I shouted in surprise. What a beautiful sea and what a beautiful world. "Small fish in colorful clothes swim freely in the water and perform touching dances; White mussels, with their mouths open, singing beautiful songs; Colorful flowers are the audience, intoxicated by this large concert. I fell in love with this place and the world at once.

Because I am very enthusiastic about people, my friends are very friendly to me. With the care of my family and the company of my friends, I grew up happily. But it didn't last long. A sudden disaster changed my life.

One day, my friends and I went to play in the water. Suddenly, I saw a ship full of rubbish coming. This is, I smell a bad smell coming on my face. Everyone on the boat was laughing, which was creepy. I vaguely heard them say, "Ha ha! If you get rich, get rid of this ship's garbage. Just go back and get the money! " One hour, two hours, three hours ... the ship is still taking out the garbage. From morning till night, the boat slowly sailed away. This is, I feel dizzy and gradually lose consciousness.

When I woke up, I found myself lying on the boat with my mother beside me. My mother saw me awake and said anxiously, "Hurry up! Come on! Pack your things! We must act immediately. " I was puzzled and asked, "Why did you move? Aren't we doing well? " "Because ... because." Mother said with wet eyes, "because everyone has lung cancer, it is the disaster caused by the disaster ship!" " "

No sooner had we walked out of the gate than we smelled a pungent smell. The beautiful place of the sea suddenly became lifeless. The warm sunshine fled to another place, and I never want to go to this disgusting place again. Dead fish bodies float in the water, giving off an unpleasant smell. Xiaohua gradually shrank and took off her colorful coat. The clam shell can no longer sing his wonderful songs. ...

My mother and I went to an unreachable place. Start over, start over. But we still can't escape human killing and pollution. Less than a year later, my mother died and I got lung disease. I lay quietly at the bottom of the sea, waiting for death.

Humans! I want to say to you: "don't destroy nature for short-term benefits." If you go your own way, you will naturally get back at you. "
