Why are there shells on the stone to write a composition?

"Hua-Hua-"A huge splash washed the shells bathed in the sun into the cracks in the rocks. Suddenly, the shell woke up. I don't know when it came here.

Looking at this dark, friendless, lonely world, it is completely desperate and even feels that it can't live any longer.

At this moment, the shell saw the sun rising from a small hole in Ran Ran by the sea, and infinite hope was waving to it. Shell thinks it can't go on like this. It decided to escape from this dark world before it died. During the day, it grinds the surface of the reef with a hard shell, supplements its strength with seawater at night, and then has a good sleep. Continue grinding the next day. Because it knows that "a drop of water can penetrate a stone and everything will come naturally." Sometimes it feels that it is the most unfortunate shell in the world, and sometimes it is optimistic that it is actually very happy.

To this day, the huge reef has been ground into a hole the size of a bottle cap by shells-you can go out. In an instant, a heat wave rolled up in the shell's heart, and it finally knew that its hard work had not been in vain. A short life, because of my faith, I survived forever. Looking at the rising sun in the east again, the shell smiled with relief. It smiles so brightly.

Yes, when you are desperate, have you ever thought about being full of hope for life? What matters to a person is not his value, but his eternal belief. I believe that with faith, your life will become more substantial and beautiful.

2. The answer to the question of shell composition

I am a shell in the sea, an ordinary shell.

Since I was born, I have lived in a dangerous ocean every day, afraid that stones will enter my mouth when I eat, but the days are not as expected by Bay. One day, a fish approached me. I opened my mouth and the fish was sucked into my stomach. At the same time, a small stone entered my stomach.

The fish was slowly digested by me, but the stone made my stomach uncomfortable.

From then on, I made up my mind to digest it, but I was wrong and the stone couldn't digest it. So, I asked my friends, and they all said in unison, "Then use your meat to grind it into powder!" " "

So, regardless of my own pain, I always wanted to grind this stone into powder, but I used my own flesh and blood to grind it for a long time, and it was still a stone, but its corners were bald and flat.

One day, the waves broke the peace of the ocean, and the fish told me that there would be a tsunami.

We were sent ashore, and a group of ants rushed up and dragged away my companion's meat. They didn't drag me away because the ants thought I was a broken shell on the beach.

The children came over and chose shells as necklaces, but I was not chosen. I promoted the glory of being Bedo. I think, I'm afraid I can only be buried in the sand in my life and will never be taken seriously.

But I was wrong. The "stone" in my body was discovered by an adult and picked up by me. The stone inside was taken out. I looked at this "stone" in surprise. It turned out to be a rare big pearl. My life has come to an end. I've already left, and I'm walking very fast, very fast.

Pearls are rare, but who would think of the hardships of shellfish when appreciating pearls?

3. Why are there pearls in the shells? Write a composition in detail, thank you ~

Not all shells are available. Only a few bivalve mussels or clams can produce pearls, which are often called pearl shells.

The mantle of mussel is invaded by foreign bodies (sand and parasites), and the epidermal cells in the affected area take foreign bodies as the core and fall into the connective tissue of the mantle. Some of the trapped epidermal cells divide themselves to form nacre, which secretes nacre and the nucleus is wrapped layer by layer to form pearl. Pearls with foreign bodies as the core are called "nucleated pearls".

After the lesion occurs, a part of the outer epidermis of the mantle is separated after cell division, and then wrapped by organic substances secreted by itself, and gradually falls into the connective tissue of the mantle, forming a pearl sac, and then forming a pearl. Because there is no foreign body as the core, it is called "seedless pearl".

At present, cultured pearls are cut from the mantle of pearl-breeding mussels by artificial methods according to the above principles, and implanted into the connective tissue of the mantle together with the artificial nucleus prepared by mussel shells. The implanted cell fragments proliferate rapidly around the artificial nucleus by the nutrition provided by connective tissue, forming pearl sacs and secreting nacre, thus producing artificial nucleated pearls. Artificial seedless pearls are pearls produced by implanting only small pieces of cells into the mantle, forming pearl sacs through cell proliferation, and secreting mother-of-pearl into the sacs.

4. Imitate the composition of "shell"

I have been a shell in the sea all my life, an ordinary shell.

Since I was born, I have lived in a dangerous ocean every day, afraid that stones will enter my mouth when I eat, but the days are not as expected by Bay. One day, a fish approached me. I opened my mouth and the fish was sucked into my stomach. At the same time, a small stone entered my stomach. The fish was slowly digested by me, but the stone made my stomach uncomfortable.

From then on, I made up my mind to digest it, but I was wrong and the stone couldn't digest it. So, I asked my friends, and they all said in unison, "Then use your meat to grind it into powder!" " "So, regardless of my own pain, I always wanted to grind this stone into powder, but I used my own flesh and blood to grind it for a long time. It was still a stone, but its horns were bald and flat.

One day, the waves broke the peace of the ocean, and the fish told me that there would be a tsunami. We were sent ashore, and a group of ants rushed up and dragged away my companion's meat. They didn't drag me away because the ants thought I was a broken shell on the beach.

The children came over and chose shells as necklaces, but I was not chosen. I promoted the glory of being Bedo. I think, I'm afraid I can only be buried in the sand in my life and will never be taken seriously.

But I was wrong. The "stone" in my body was discovered by an adult and picked up by me. The stone inside was taken out. I looked at this "stone" in surprise. It turned out to be a rare big pearl. My life has come to an end. I've already left, and I'm walking very fast, very fast.

Pearls are rare, but who would think of the hardships of shellfish when appreciating pearls? .

5. Write a composition with sand, sunshine, rivers and shells.

On the beautiful beach, there are a pair of good friends, namely shells and sand. But an unpleasant thing happened between them.

One day, several children went to the seaside to play, and one child found a beautiful shell. Shells are sparkling, colorful and beautiful. The children said, "What beautiful shells!" Hearing this, the shell was elated. Soon, the children ran away. The shell said to the sand, "look, people praise me for being beautiful;" And you are so ugly, it's a failure to be friends with you! Sand smiled and said, "You are really beautiful, but your beauty and brilliance didn't appear until we touched you." . ""what? I need you. What a joke! "The sand stopped talking." Talk to me! Tell you, from this moment on, I want to make a clean break with you, and I don't want to mix with such ugly things as you anymore! "Sand can't help it. Not to be outdone, it said, "Even if we are separated, we don't have to quarrel with me." The shell said, "I don't want to see you again for a moment." "

When the sea heard the conversation between the shell and the sand, it surged and swept the shell into the sea. The shell just landed on a rock at the bottom of the sea, feeling very comfortable, thinking: I finally got rid of the disturbance of sand. Shells are in the vast sea, and there is nothing but blue water and rocks. A few days later, he felt lonely and couldn't help thinking of his good friend Sandy. It said to itself, "I really regret it!" " If I hadn't complained and left the sand, I wouldn't have lived such a lonely and painful life. "Shell remorse. This time is no longer so beautiful, because without the friction of sand grains, it becomes rough. When the sea heard the sound of shells, it sent them back to the beach. The shell returned to the beach. It blushed and said to the sand, "I'm sorry, sand, I was wrong about you." Please forgive me. " The sand said, "It doesn't matter. Let's be good friends again. " Hearing this, moving tears welled up in the shell's eyes from time to time. Since then, shells and sand have been reconciled.

Yes, no matter how beautiful a person looks, if he has a proud heart, he will lose many friends around him; Although a person's appearance is a bit ugly, if his soul is beautiful, it shows that he is a kind and upright person, and inner beauty is the most important thing.

6. Composition of Shell Company

Shell life

Pearl is the glory of life brewed by a shell after suffering. Life is like a shell, and shells live. Yes, just like your mother.

-inscription

My father who came back from a business trip brought a pearl necklace to my mother who came back from a business trip. Looking at the big ivory pearls on it, my thoughts suddenly returned to the time I spent in Beihai that summer vacation.

"pearls are round particles produced in the shells of some mollusks (such as mussels), which are milky white or yellowish and shiny. It is formed by the pathological changes in this kind of animals or the entry of sand grains and microorganisms from outside into their shells. Used as an ornament ... "Looking at the motionless shells in the water, listening to the staff's detailed explanation of pearls and shells. They are neither biology teachers nor biologists, but they know a lot. I listened to his explanation with great interest, imagining in my mind that these shells were struggling in pain. After a period of time, beautiful pearls will be bred in their bodies, and I suddenly feel a little sad and sad. Maybe it's pity for these little creatures. So I stopped listening, turned and walked outside the pearl factory, staring at the sea. The pain of the shell is stuck in my heart like a small stone. However, with the passage of time, that memory was gradually forgotten. Looking at this necklace now, my memory is gradually coming back.

Look at the happy mother's face wearing a necklace. Although it is still so gentle and beautiful, it is no longer so radiant. The passage of time, the torture of disease, in front of this strong woman who has been running around for many years, mercilessly carved a mark. A mother can't see her children all day, can't enjoy the warmth of her family, and runs around the land of her motherland alone. I don't know how much pain she has experienced and endured in recent years. To be sure, my mother must be a successful woman, although she doesn't earn as much money as Bill Gates. Mom is very successful and great. There are two children at home, which is doomed from the beginning. In today's society, if you want your brother's family to live a happy life, your mother's responsibility is much heavier. My mother is a strong person. From Shaanxi TV Station to Phoenix TV Station, and then to Shanghai Wenguang, my mother went to Shanghai from xi 'an to work hard. With her own strength and love for her family, she kept moving forward. Those feet have gone through most corners of the motherland and many parts of the world, and my mother has never stopped trying. Loneliness can't make her shrink back, and illness can't stop her. How many times, watching my mother leave alone with luggage, that figure is taller and stronger than Valkyria. As time goes by, every effort of my mother is like a pearl, shining with undiminished brilliance in my memory.

Today's mother, who has just experienced the torture of lumbar hyperosteogeny, went home during a short sick leave, in order to give her children the maternal love they didn't get, and also to let her tired heart rest at home for a while. In fact, my mother's running is the embodiment of maternal love, so I don't know. A string of pearl necklaces strings up our memories, just like mother's love and her dedication. Think about it this way, how appropriate this necklace is for mom! Mother is like that shell, hiding her home in it and guarding it with love. Once there is any difficulty, she wants to come in, and the love that wraps everything will turn the difficulty into a pearl. Mother used her own pain to make life and love create ordinary and extraordinary miracles.

My mother used her own experience to tell me the meaning of real strength and suffering to life. I will never forget my mother's back, like a pearl brewed with a shell and shining life.

Life is like a shell, and shells live. Yes, just like your mother.

7. The composition materials of stone books and why they are called stone books.

I am a stone book. Although I am a bare stone, I am actually a book. You see, I am layer by layer, isn't it like a thick book? I still have words on me You come to see me, this is the footprint left by a light rain, called raindrop mark; This is the footprint left by the waves, called wave mark; And those small, yellow, black, red, shiny and transparent ... are called minerals. These are all words on my body.

I have not only words, but also pictures! This is a leaf, which can tell me that it used to be a dense forest, with flowers and grass on the ground and many insects. This is a shell, where there is a small fish. It can be proved that after a long time, this is the sea. When they die, fossils will be printed on it.

Careful people will find that my book can tell you which mountain is buried with coal and which one is buried with ore. I really have a lot of knowledge

8. composition about stones

In a dense forest, there lived a small stone family. Xiaoshi is very obedient and often helps her mother do many things. His mother loves him very much.

One day, the forest where Xiaoshi lived sank, and Xiaoshi and his family also sank. Xiaoshi gradually fell asleep in the sea. Ten thousand years later, the bottom of the sea rose and Xiaoshi woke up. He opened his eyes and looked around and found himself sitting on the top of a high mountain. Xiaoshi also found a complete fishbone in his stomach. Xiaoshi was surprised and said in surprise, "Why is there a fishbone on my stomach?" This sentence woke up the sleeping stone mother, and Xiaoshi quickly said, "Mom, look, I have changed!" " "Mom said," little thing, you have the wrong mother. Go back to your house. "

Xiaoshitou can only go to school by himself. When I arrived at school, many students in Xiaoshi also had such pictures on their stomachs, including shells, small fish, kelp and conch! Xiaoshi was sad to hear another voice laughing at his ugliness. Xiaoshi picked up a bag and ran away with it on his back.

One day, he came to the seaside and began to cry. A dolphin surfaced and asked Xiaoshi, "Little fossil, why are you crying?" Small stone said, "My name is not small fossil, I am small stone." Dolphins saw the small stone, didn't know it was a fossil, and didn't want to disturb it, so they swam away.

Suddenly, a scientist came, looked at the little fossil and took it home. Later, small fossils were sent to the museum and became fossils for everyone to watch.

Although the little fossil can only lie there quietly, he thinks: it is a happy thing to contribute to science! Since then, small fossils have become the most familiar fossils for children.

9. Write my composition about picking up shells at the seaside.

During the summer vacation, my father took me to swim in Ganjiang River. What impressed me most was picking up shells by the river.

The low tide in the morning is a good time to pick up shells. We drove to the river to prepare for a big fight. I took off my shoes and stepped on the soft sand. Very comfortable! Several islands in the distance, like shining pearls, are bathed in their mother's arms. Although the soaring scenery is beautiful, I can't appreciate it because I find the shells on the beach are beautiful. Looking down, these shells come in various shapes. Round, pointed at both ends, flat and prickly. It's hard to describe it in words.

I picked it up and summed up my experience: I can get a few by touching it in the water; The most selective place is on the boutique beach; Dig the sand by hand, maybe there are many shells waiting for you.

At this moment, my father came over. He won many victories and caught seven small shells. My mother is good, too. Two plastic bags are full and tightly sealed, and it seems that they can't be packed quickly. The beautiful shell alone accounts for most of it.

"Wow!" Snow-white spray rides on Mother Hai's arm and gently slaps her brother on the beach. The tide began to rise and we had to leave the lovely beach! Goodbye! Beautiful beach!
