How do marine fish write a composition?

1. How to write the composition of marine fish? You can refer to the following information:

Most marine vertebrates breathe through gills, move with fins, have scales on their bodies, and generally have swim bladders and temperature changes in their bodies. There are more than 20,000 kinds of live fish, among which marine fish is about1.20 thousand, which is the most prosperous fish group. A brief history of research generally believes that the study of marine fish began with Aristotle, a Greek scholar in the 4th century BC. In his book Zoology, he recorded 1 15 species of Aegean fishes, and made a systematic description of their structure, reproduction and migration. The study of modern marine fish began with the Natural History of Fish published by French scholars G.B. Ju Ye Wei and A. Valencia (1828~ 1829). Since then, many countries have conducted a lot of investigations and studies on the migration, reproduction, growth, distribution and development of marine fish resources, among which Challenger and Albatross are the most important. Since 1950s, new technologies such as electron microscope have been widely used to study the occurrence, organization, physiology and ecology of marine fish. China is one of the earliest countries in the world to exploit and utilize marine fish. 1975 The ancient tomb excavated in Jiaozhou Bay, Shandong Province, confirmed that China was able to catch many kinds of marine fish as early as the Neolithic Age, namely giant salamander, barracuda and snakehead. The Chronicle of Bamboo Books (Ancient Edition) records that the Xia Dynasty was "hunting in the east and catching big fish". After the Qin and Han Dynasties, there were some protective measures for fish resources, such as "it is not advisable for fish to grow". Tu Benjun's Misunderstanding in the Sea of Fujian in the Ming Dynasty described in detail the habits and fishing dates of 129 species of fish along Fujian coast. Hao Yixing's Mistakes in the Sea and Guo Baicang's Mistakes in the Sea in the Qing Dynasty recorded the knowledge about the growth, reproduction and ecology of marine fish. After the founding of People's Republic of China (PRC), a large-scale survey of marine fish in China was carried out, and books such as Fish Survey Report in the Yellow Sea and Bohai Sea, Fish Fauna in the East China Sea, Fish Fauna in the South China Sea, and Chondrichthys Fauna in China were published successively, and studies on fish physiology, ecology and genetics were carried out.

2. I am a small fish. I am a fish living in the sea, but my hometown is in a clear and transparent river.

Life in the river is really happy. I swim in the water with my friends and sing happily every day. Round and round among the soft water plants, you chase after me; We often take the round lotus leaf as an umbrella, hide under it and play happily. Sometimes I lean out of the water and greet my friends on the river. At that time, the sky was so blue, like a big sapphire, and birds could often be heard playing happily ... every day I entered a sweet dream in the fragrance of flowers.

Who knows, one morning a few days later, a loud noise broke my dream. What's going on here? My heart is full of curiosity and fear. Swim to the surface in a hurry to find out. When I reached the surface, I was shocked. The whole forest is dusty, and the lush trees in the past crisscross. Deer, rabbits and foxes, including tigers and lions, all look flustered, as if the sky is falling. I finally stopped a rabbit, and it stammered, "here comes the man!" Saw ... saw ... the tree fell, and the home ... the home was gone. Run for your life! "

Is home really gone? Do you want to leave? I walked back in frustration. Suddenly, I smelled a bad smell. There were large pieces of dirty things floating on the water, which got on my beautiful clothes and could not be washed off. Before long, many of my peers got sick, some got sores, and some became strange gradually. Everyone sighed and had to leave this home that once brought us infinite happiness in droves.

After a few days, the water became more and more turbid, the smell became stronger and stronger, and there were more and more dirty things, so it was impossible to survive. So I left my hometown and swam to the beautiful sea. Who knows, the sea has become dirty, and black oil flowers are floating on the water from time to time. I had to dive into the water and swim to the deep sea.

Later, I learned that humans cut down trees to bring convenience to them. Sewage from human factories is discharged into the river, which makes the water turbid. Some people throw rubbish into the water at will, making the water smelly and dirty things floating on the water. There is also some oil flowing into the sea, which pollutes the sea and hurts birds that catch animals in the sea ... Humans have polluted our living environment for their own convenience, made so many animals homeless and destroyed the beautiful nature.

The environment is so bad now, didn't you humans make it yourself? Do you really want to destroy the world like this? I don't understand why such a beautiful world and such a beautiful home should be destroyed. She is our mother earth and raised us. There is only one Mother Earth. Can't you take good care of her? (Ding Bo Literature)

Stop cutting down trees. She is mom's hair. Do you want to take her head off? Don't litter. That's mom's clothes. Do you want her to wear dirty clothes? no ...

3. fishing for sea fish composition finally saw the real sea. I picked up a lot of shells on the beach, bought two starfish nearby and went to find crabs.

Sea crabs are the same color as sand, so they are hard to find. I dug and searched on the beach, but I still couldn't find it. Dad got nothing. "Found a crab!" Where is it? Wow! What a lovely little sea crab Still alive, others don't seem to find crabs, hee hee!

I came to the seaside, and the waves came one after another. It's so comfortable The tide is rising now! Found a marine fish, although it was dead. Sea fish are very long and have a sharp mouth.

To go, I reluctantly left the beach.

"When I was a child, my mother told me that the sea was my hometown ..."

4. Fishing for Marine Fish Interesting Summer Vacation Wei Wenbin, Class Two, Grade Four, Pingliang Railway Middle School, Gansu Province, took a vacation this year. I spent it at my grandparents' house.

One day, it was sunny and sunny, and I went to play in the vegetable field with some friends. As soon as I entered the vegetable field, I saw tall poplars growing on both sides of the road, and green vegetables were planted in the field, including potatoes, cabbage, carrots and so on.

We play games under a tall poplar tree. Suddenly, a "black thing" flew into the little friend's neck. He felt itchy, touched his neck, took out a black bug and shouted, "I caught a longicorn!" " Oh! So this black thing is longicorn.

It has a pair of long tentacles, two thorns on its neck and yellow dots on its back. I remember my grandfather told me that longicorn beetle, longicorn beetle, is a pest. It lives on poplar trees and lives by sucking the sap of trees.

So I said to my little friend, "longicorn beetles are pests." Let's catch them and play. " I got a bamboo pole and found a longicorn, so I pulled it out with a bamboo pole and fell from the tree.

After a while, each of us caught one. I suggested: Who are we faster than the longicorn? Let's name the longicorn and start the game. My longicorn is called "General Blackhead".

At first, "General Blackhead" was far ahead. After a while, the obvious "Big Marshal" slowly caught up from behind and gradually approached my "Blackhead General". I tried my best to cheer for it. It seems to have understood my words, gradually accelerated its speed, left another longicorn behind and won the championship. I am very happy. The longicorn competition is really interesting! Last summer vacation, my parents and I made an appointment to hold a "family quiz".

The summer vacation is coming. On the day of the competition, I first learned the appearance of the host on TV, walked onto the stage, cleared my throat and said, "Now, I declare that the family intelligence competition has officially begun. First of all, we ask red mother to answer the question: what is classical Chinese? Please give an example. "

After hearing this, my mother thought for a while and said, "Classical Chinese refers to a poem with characters, feelings and sense. For example, the ancient narrative poem "Learning Games" tells us that we should concentrate on studying or doing anything, otherwise we will accomplish nothing. " I can't help clapping my hands and saying, "That's right, the red edge adds ten points."

After that, he turned and wrote "Jia 10" on the blackboard. "We asked Dad Lan to ask a question: Two geese were put in the refrigerator at the same time. An hour later, one was killed, but still alive. Why? " "Well, well ..." Seeing that my father couldn't answer, I revealed the answer: "Because that goose is not an ordinary goose, it is the owner of the Antarctic-penguin, so I gave Blue ten points less! The following is a joke contest. No matter what jokes you tell, as long as you make your mother-in-law happy, you can get extra points! " As soon as the voice fell, my mother raised her hand and said, "Once upon a time, there was a king of jokes. Once, he broke into a house by mistake and was caught. When the man heard him say that he was a famous joke king, he asked him to say a word to make him laugh. The joke king said a fart word without thinking, but the man didn't understand what it meant. The king of jokes said,' It's up to you to let it go or not. "I couldn't help laughing, even my mother's rival dad laughed ... and finally my mother won 20 points. This "intelligence contest" is really interesting. It not only enriches our Chinese knowledge, but also tests our intelligence and adds endless fun to our family.

Interesting summer vacation: Baby Xu from Class 5, Fengshun Primary School, Fengshun County, Meizhou City, Guangdong Province, is extremely happy during the long summer vacation. Now, let me tell you an interesting story about summer vacation.

One day, I stayed at home and felt very puzzled. Suddenly, I had a brainwave and thought of a good idea.

Is to play nose-to-nose with my sister. I told my sister what I thought, and she readily agreed.

I first drew a clown doll with no nose on the blackboard. My sister found a magnet instead of a nose.

I started sticking to my nose. My sister first covered my eyes with a piece of cloth. I walked slowly to the blackboard, touched it left and right, and found a place to put my nose.

At this moment, my sister smiled. I pulled off the cloth and saw that the clown doll not only had no nose, but also had a mole on its mouth.

My sister proudly said, "Look at me." I saw my sister hurried to the blackboard and found a place to set her nose.

I couldn't help laughing when I saw it. Sister quickly took off her cloth and smiled. It turned out that Eva the clown not only didn't have a nose, but turned into a cyclops.

The clown baby seems to be particularly angry. At this time, my father heard the laughter and came over and asked, "What's so funny? Tell me about it. "

My sister and I winked, walked up to my father, blindfolded him and stuffed my nose into his hand. Dad understood what we meant, slowly approached the blackboard, found the right position and lowered his nose.

"The clown baby has a nose!" We cheered. Interesting summer vacation During the summer vacation, my mother took me to catch fish in the pond. A fence was built around the pond, and many green trees were planted outside the fence. There is an aisle where people can walk, and there are several birds singing in the sky, which makes me want to see what the pond looks like as soon as possible. When I entered the fence, we immediately began to catch fish. I caught two or three fish as soon as I caught them, and soon I caught a small bucket of fish and jumped around happily. After a while, I grabbed it with a jerk. Wow! A shrimp, this shrimp is silvery white, and its two beards stand high, as if to say, "Look at me!" " Suddenly, a white bird flew by. I asked my mother, "What kind of bird is this? "My mother said." This is an egret, and' a line of egrets goes to the sky' is a description of egrets. "I asked again," Is it going to heaven? " Mom smiled and replied, "This is the arrangement of heaven. How is it possible? "I think, I'm so funny, I can't even tell flying in the blue sky, really! Later, we caught a lot of fish. Although the weather is very hot, we are still very happy. I thought: Next time I will ask my mother to take me fishing here. This year, the sun was shining on the moon and the heat was unbearable. I want to sell watermelons.

At noon, bring it.

5. How to write a composition with strong winds, streams, leaves, sea and fish? Autumn has come, the big leaves beside the stream have turned yellow, and a leaf has staggered into the stream. The stream said to the leaves, "Welcome, Miss Leaves, let me take you to a distant place." The leaves were sunburned all summer, and the stream was cool and comfortable, so I happily agreed, "OK, OK, where shall we go?" The stream said, "I'll take you to see the sea!" " Leaves don't know what the sea is, so they ask, "What is the sea like?" Is it far? "The brook said longingly," The sea is very big and blue. There are many fish and shrimps in it. There are boats on the sea. There are many seagulls flying on the sea. " .。 . . 。" Yezi thought the sea was beautiful, so she accompanied the brook towards the distant.

Suddenly, the leaves saw a small fish and said to the stream, "Look, there is a fish in the stream. Have we reached the seaside? " The stream said, "No, it's just a small fish in the stream." Seeing the leaves, the fish asked doubtfully, "Leaves, leaves, why did you come to the stream?" The leaves said, "Autumn has come, and I can no longer live on the nutrients of big trees, so I fell down.". I want to see the sea with the stream! " Fish said happily, "I'll go with you." I also want to see the sea. "The stream and the leaves said with one voice," good! "

The stream swam to the sea with leaves and small fish. . . . . . How happy they are to finally see the sea!

6. How to write a composition People use words to express their thoughts and feelings, but what readers see is far beyond plain words. They rely on imagination to turn words into three-dimensional pictures. Therefore, the sound, color, taste, change and contrast in composition are particularly important.

A good cook should not only cook well, but also know how to arouse the appetite of diners, so that people who see it will want to eat and those who eat it will be satisfied. Therefore, the chef pays great attention to the arrangement of food and makes the food look delicious.

1, sound

Can you imagine watching a silent movie? Without sound and color, the effect will be greatly reduced.

In a composition, the voice is definitely not the protagonist, but it is necessary and appropriate to add sound effects to make the article more vivid and friendly.

In the writing of scenery, sounds reconcile too many defects in the picture, so that the sounds of nature, such as raindrops falling, wind blowing through leaves, insects singing and birds singing, waves lapping on the shore, and different sounds of the city, can explain what you want to convey.

You can also add sounds to other topics, such as crying, heartbeat, clearing your throat, footsteps and so on. As long as you listen attentively, you will feel the sounds of words, and with a little thought, these sounds can embellish your composition.

Step 2 color

We live in a colorful world. It is impossible to write articles in black and white, but there are many compositions in black and white.

Color composition depends on observation, and what color should be highlighted under what circumstances; What color sets off what mood, there are certain rules in the world of words. It is necessary to read more books and think more, so as to grasp it accurately.

For example, the wind has no color, but we can bring out different colors through the wind. The wind blows through the green trees and grass, the blue sky, the red roof and the blue sea. The wind even blows your black hair and melancholy heart.

Of course, you don't have to. If it's not the right color, it will look out of place.

Step 3 smell

In real life, the smell is invisible, but it definitely exists. Just like the smell of a delicious food, it can't fill the stomach, but it makes people's appetite increase greatly. Smell replaces sight, hearing and touch at critical moments. For example, if the food goes bad, we may not see it, but we can definitely smell it.

The smell of composition makes the expression more diverse and vivid.

For example, the wind, the taste of the wind depends entirely on which direction it comes from. The wind blows across the coast, bringing a strong smell of salted fish;

The wind blows through the garbage chute, and you smell rancid; The wind blows through the happy people, and you can even smell the beautiful breath in their laughter.

Whether it is a beautiful smell or a disgusting stench, there is a beauty that makes the finishing point.

4, change and contrast

Changes can be identified with the naked eye, such as the shift of sunlight, people's emotions and expressions. Change can also be indirect, such as a person's change, or a process of growth and aging, which we may not notice in a short time.

But it has been going on all the time, and the application of changes can make the article hierarchical and deeper.

Contrast is often inseparable from change, but the use of contrast is stronger. Whether it is color, sound, darkness, emotion or behavior, the function of contrast is to create conflicts and make readers feel shocked. In contrast, the meaning we want to express will be clearer and the effect will be remarkable.

Using variation and contrast in composition can show the author's careful observation.

5. Summary

When a chef cooks a dish, he will not only pay attention to color and seasoning, but also reverse the light and heavy, destroy the characteristics of raw materials and make the food lose its original flavor. Similarly, when writing an article, we should not pay too much attention to the use of skills and cover up the thoughts and feelings we wanted to express.

A good composition should be balanced, important, sequential and primary.

7. My hometown is located around a bustling city. When I came to the village entrance, it was a crowded vegetable market.

There are five big characters standing next to the vegetable market-"the seven surnames of Kangshan Village".

The pond in the morning is a happy pond. At that time, large and small fish, men, women and children, will get together to play. Some fish even jump out of the water, wag their tails a few times and then fall into the water quickly.

The pond at noon is a silent pond. At that time, it may be that the fish was taking a nap, or it may be that the fish was afraid of the heat and hid under the pond to enjoy the cool! The pond is so quiet that you can hear a needle drop to the ground.

In the afternoon, the pond is cheerful and lively. That's because I like no fish looking for food. Some fish use their mouths to move water, and the water immediately ripples. Some fish even ran to their companions, knocked them to the ground and took their food! They compete for food to make the water shine.

Ah! I like the pond in my hometown. Until now, my memory is still flowing in the pond. This is the pond in my hometown. (article

8. Write 400 words about iodine On Friday, Teacher Chen showed us a video about iodine deficiency. Iodine is an indispensable rare element for human body. In iodine-deficient areas, many people get big neck disease, which is the result of iodine deficiency. Lack of iodine in pregnant women is likely to lead to miscarriage. Even if children are born, they are not healthy, and most of them may even be mentally retarded.

Looking at the faces with some dementia, I looked at the front with empty eyes numb, and there was no mood fluctuation in my eyes. I can't help feeling a little sad. God gave them bodies in life, but not souls. Without self-care, they are like cold machines, walking dead. Living means nothing to them. Have ears but can't understand anything; Have eyes but can't understand anything; A mouth can't explain anything; Have brains but don't know what to think; Have a life but don't know what to pursue. Without dreams, they always seem to be inseparable from their parents who raised them from childhood.

Finally, iodized salt was produced. These iodized salts were not distributed to areas with high iodine content, saving the lives of countless children. We are lucky, we have pursuit and running in life, and we will learn everything as soon as we learn. Every pair of eyes is bright, intelligent, emotional and dreamy. The limbs are also healthy, with clear consciousness and clear thinking. Maybe some people will only sympathize with those who are not sound, in fact, we are more worthy of sympathy, because the brain is not used all the year round, which leads to rust.

If you want not to lose yourself on the road of life, you must first learn to chase and run in life, and your thoughts will never stop.
