Dolphins took the lead in writing a composition in the first grade.

1. composition, write the characteristics of dolphins (grade one) special dolphins.

I wrote this dolphin, you must think there are dolphins in my family! That's impossible, because the dolphin I'm talking about is a luminous dolphin toy, which is of great use to me.

The origin and appearance of dolphins Speaking of the origin of this dolphin, I bought it last time I went to Changsha Underwater World. I was watching all kinds of fish in Changsha Underwater World. Suddenly I saw a glowing dolphin. It emits red light first, then yellow light, and finally green light ... just like a chameleon. I thought this dolphin was beautiful, so I bought it. I looked at it carefully and found that as long as I shook the dolphin, the silver piece jumped up, like a fairy scattering flowers, and it was beautiful.

The role of dolphins One night, the power went out at home, and it was dark everywhere, and almost nothing could be seen. I walked into my room unconsciously. I seemed to see the street lamp outside and looked at me like a pair of magic eye. Even the books on the table said to me like a magic face, "I'm going to eat you." I stammered in horror: "I … am … not … afraid of … you." I suddenly touched the dolphin I bought. I quickly turned on the switch and colorful lights filled the room. At this moment, the dolphin seems to say to me, "Master, I won't make you afraid." At that time, I was so glad to have this dolphin with me.

I like you-this special dolphin, because you make me feel very happy. When I need you, you appear in front of me in time, and I will learn from you the characteristics of being helpful in the future.

2. Write a composition on the topic of dolphin skills. Describe the first article through one thing: dolphins.

Everyone has seen dolphins! Mammals, too. Mammals are viviparous!

I have seen dolphins with my own eyes. Dolphin is a smaller whale, which is distributed in all the oceans in the world. Body length 1. 2~4。 2 meters, weighing 23~225 kg. Dolphins generally have sharp mouths and narrow teeth. They are mainly eat small fish, squid, shrimp and crab. You have no idea how dolphins sleep! Dolphins never seem to sleep and swim. Even if they want to sleep and swim, dolphins breathe with their lungs. The ultrasonic waves emitted by dolphins can clear our heads, but they are also quite harsh! There are many kinds of dolphins, and dolphins are also very smart. Do you remember Dolphin Lele? It can add, subtract, multiply and divide within 20! Do you know why dolphins swim fast? On the dolphin's body, the slippery skin is not tight.

Dolphins will shrink their skin when swimming, and there will be some small things to store water, so that a protective layer of water will be formed around their bodies. When dolphins swim fast, the protective layer of water will cover their bodies, so that dolphins can swim fast, and dolphins are also our good friends, and dolphins have also saved us! We can't forget it!

I like dolphins, dolphins look so cute! Especially since I saw dolphins with my own eyes and shook hands with them last time, I like dolphins even more! I can't forget the scene! I really want to take photos with dolphins again!

The second article: lovely dolphins

On a holiday, my mother and I went to see an interesting dolphin show. A dolphin show, wow ... great. Really * * *.

Dolphin, what a lovely animal! Look, shiny as oil. What about that tail? Flexible swinging from side to side is very funny.

With the melodious music, the dolphin show began. Ah, the dolphins actually danced with the wind. You see, it stands upright and its tail is swinging rhythmically in the water. That pose is really like a talented dancer!

The wonderful performance of dolphins attracted bursts of laughter and praise.

"The second program-dolphins save lives, is really novel. I quickly stood on tiptoe, craned my neck and opened my eyes. Suddenly, "plop, a child fell into the water." I saw the child drifting in the water. It seems that he can't swim. I'm out of breath. At this time, the dolphin swam to the child quickly, and the child hugged it, and it swam back with the child. The child was saved, and a stone in his heart fell to the ground. I think: Dolphin must be a kind of animal friendly to human beings. No wonder someone likes it.

Composition describing the appearance of dolphins (5 articles)

"Look, the dolphin is heading the ball!" The shouts interrupted my thoughts. I looked back and saw five children standing on the shore, each with a ball in his hand. The first child threw the ball out and the dolphin stared at it. When the ball was about to fall into the water, it quickly used its first head. Wow, hold on! The audience cheered.

The second, third and fourth children threw the ball in different directions in turn and were firmly supported by dolphins. It's the last child's turn to pitch. He deliberately made it look like it was thrown far away, but the ball landed on the edge of the pool. The dolphin swam at an amazing speed, gently used the first one, returned the top of the ball to the children, and then swam away easily. It seems to say, "You want to test me, I'm not afraid. Come again! " !

From time to time, I recall the scene of dolphin performance. What a lovely dolphin! What an interesting performance! What a happy festival.

3. Letter to Dolphin I think everyone will like the name dolphin after listening to it, because dolphins are smart and sensitive, and they can perform after training! Although dolphins are smart and sensitive, they are very rare in the world. We should protect them! Dolphins are mammals. They often live in groups. Dolphins often swim out of the sea and feed on turtles, squid, shrimp and crabs. White dolphin is one of the most primitive dolphins in existence, and it is a rare animal in China. Dolphins are not only clever, but also very obedient to the orders of the group. If one dolphin swims to the shore, other dolphins will swim to the shallow water near the beach. Dolphins don't return to the sea quickly at low tide. If you don't believe me, I'll tell you! One morning, while a warship was moving, a big wave suddenly struck and sank the ship. All the navy soldiers fell into the sea and died except the captain fainted. At this time, a dolphin carried the captain on his back upstream to the shore, threw him ashore with all his strength, and then returned to the sea. When the captain woke up, he saw the dolphins jumping there and knew that they had saved him. He formed an army against dolphins. The most interesting thing is that dolphins have noses on their heads. I like such dolphins. I remember once in Hong Kong, my mother and I watched an interesting dolphin show, the composition of the sixth grade in primary school, Dolphin Composition. The dolphin show began, and the trainer released a dolphin from the water cage. At the command of the trainer, the dolphin jumped out of the water, and then the lovely dolphin leaned out and shouted at the trainer. I think dolphins feel very good. I wanted the trainer to feed it. As expected, the trainer took out a yellow croaker from his pocket and fed it to the dolphins. Then the trainer asked us to do an arithmetic problem. A sister said that four plus five equals several. The dolphin jumped out of the water and patted the water with its tail, and * * * slapped it five times. Then the animal trainer called us and explained that the dolphin asked my sister if my answer was correct. This is really an interesting performance. I want dolphins to walk and talk, which is so interesting. Dolphin composition is 600 words.

4. How to write a dolphin composition Dolphins are the floorboard of small toothed whales.

People usually call toothed whales about 3 meters long dolphins. There are many kinds of dolphins, including finless porpoise, true dolphin, bottlenose dolphin, Chinese white dolphin and striped dolphin.

Since ancient times, dolphins have played a major role in many fables. In modern times, it has become an important research object for many scientists, a right-hand man for marine workers and an important resource for aquaculture.

What animal is a dolphin? There are many stories and legends about dolphins saving lives. In modern times, such stories appear frequently.

How to explain this behavior of dolphins? Scientists speculate that this may be an instinct of it. Dolphins like to play and often promote the game of floating objects at sea.

Therefore, when a dolphin meets a drowning person, it may mistakenly think that it is a floating object, and instinctively lift it and push it ashore, thus saving the person. Dolphin is really a gentle animal, friendly to people, and likes to make friends with people even under natural conditions.

It is very docile and likes to play with swimmers. People used to say that monkeys are the cleverest animals in the animal kingdom.

But it turns out that dolphins are smarter than monkeys. Some skills, monkeys have to go through hundreds of trainings to learn, while dolphins only need 20 times to learn.

If the intelligence of animals is measured by the percentage of the brain's weight, dolphins are second only to humans and monkeys are third. After training, dolphins can not only perform various skills, such as heading the ball and drilling the ring of fire ... Moreover, after special human training, they can act as people's assistants, put on grabbers, dive and salvage things that sink on the seabed, such as rockets and missiles for experiments, or pass information and tools to people engaged in underwater operations, or even conduct military reconnaissance and even act as "death squads", carrying explosives and warheads to attack enemy ships or blow up enemy underwater missiles for launch.

5. Watching Dolphin Performance Composition Watching Dolphin Performance Composition Today Saturday, my parents took me to Changsha Zoo to watch dolphin performance and dolphin performance composition. After breakfast, I was the first to get in my father's car, hoping that the car would get to the zoo earlier. About half an hour later, we finally arrived at the place where the dolphins performed. After a while, the performance began. I saw the dolphin trainer make a gesture. Two lovely dolphins were led out, and only the audience applauded warmly. Dolphins performed one program after another after hearing applause. The composition "Watching Dolphins Perform" was written in the sixth grade of primary school. First, the dolphins salute the audience with their forelimbs. When the dolphin trainer sees that the dolphins are doing well, he gives each dolphin a fish to eat. Then the dolphin trainer threw two balls into the water. Seeing these two balls, the dolphin freely entered the water and propped on it. Gestured to the audience, he proudly threw the ball out of his mouth, jumped up and caught it, and won applause from the audience again. Finally, two dolphins jumped out of the water and put their forelimbs on the stage as if to say goodbye to the audience. After watching the dolphin show, I reluctantly left the zoo. On the way back, I was still thinking, I don't know how much effort the dolphin trainer has put into training dolphins so well, which is really remarkable. Watch dolphins perform 350-word compositions.

6. Composition about Dolphins 50 words Dolphin, the name is no stranger to us. Because most of us have seen the wonderful performances of dolphins on TV or in movies. Watching dolphins sometimes head the ball, sometimes swim, and sometimes jump out of the water and somersault in the air. How interesting! But I wonder if you have ever wondered why dolphins are so obedient?

To understand the characteristics of dolphins, we must first understand its genus and habits. Dolphins are deep-sea mammals. It's big, but its eyes and mouth are small. Its skin has no scales and is as smooth as oil. It likes eat small fish shrimp. Because it plays an important role in the study of biological evolution, people in the scientific community are very interested in it. Many countries have experts who study dolphins, so dolphins have survived and become one of the protected animals.

One of the biggest characteristics of dolphins is that they know "a language similar to human beings". Mr Herman, director of the Marine Mammal Research Institute in Honolulu, USA, once conducted an experiment: two female dolphins "Phoenix" and "Aki Ke Mei" received a 7-month advanced behavioral pre-training course, and the animal trainer rewarded the dolphin's sounds, gestures, objects and behaviors, and then turned to the language learning stage. According to the data published by Herman, "Phoenix" is familiar with 368 sentences, of which 85% can answer correctly. Aki Ke Mei knows 308 sentences and can answer 83% of them correctly. This shows that it is not a lie for dolphins to know "human language".

So why do dolphins understand "human language"? Scientists believe that although dolphins use vision in the wild, they use hearing to identify directions. They can exchange information with special whistles or "clicks". Therefore, as long as the simple human language is input into the computer, and the computer controls the waveform generator to send out underwater flute signals which are convenient for dolphins to identify, dolphins can be commanded to swim.

Of course, dolphin language also has a grammatical rule, that is, physical words (objects) must be placed in front of behavioral words (predicates), and modifiers must also be placed in front of physical words. For example, if you want dolphins to walk to any window under the swimming pool and touch the window with their tails, then the password must be: "window, tail-contact." In this way, dolphins will do it. This shows that dolphins also speak language art!

In addition, dolphins have a special place. It has two brains. For this, no other animal in nature can catch up with it. The two brains of dolphins can work alternately. Therefore, we see that dolphins always jump around from morning till night and refuse to sleep. How can two brains be sleepy?

Dolphins are very kind. Since ancient times, dolphins have made many "heroic achievements" in piloting, saving lives and delivering letters. With the development of science today, the relationship between dolphins and human beings is closer. I believe that dolphins will become one of the friendliest and closest friends of mankind in the near future.

7. Cute little dolphin composition I have a cute toy-a little dolphin.

It has dark blue skin, a white belly, a pair of lovely eyes, and is radiant. It has pectoral fins like small fans on both sides of its body. On the blue sheets, it seems to have returned to the embrace of the sea, and there is a fan-shaped tail that keeps swinging and swimming happily.

When I picked up my beloved dolphin and played with it, I stood it up, nested its fan-shaped tail tip into a pair of calves, and put its pectoral fin next to my stomach. It's like a puppy standing up and asking for food. Sometimes I throw it into the air, just like a real dolphin flying from the sea, chasing its prey. I rub it with my hand. He circled in the air and on its pectoral fin. Its graceful dancing brought me into their free group.

Some people head the ball, some people sail on the water ... and live a happy life. Little dolphin is my best toy. It brought me many happy times.

Make my life more colorful. My little dolphin is so cute.
