Snail fourth grade composition

In daily study, work and life, everyone has dealt with writing. With the help of words, people can reflect objective things, express their thoughts and feelings, and transmit knowledge and information. How to write a thoughtful and literary composition? The following are 9 compositions of snail level 4 collected by me for your reference, hoping to help friends in need.

Yesterday, I caught several snails. The biggest one was as big as two grapes, like a "big MAC". Its shell is round and has six colors: red, green, yellow, gray, black and white. It has two pairs of antennae, one long and the other short. The long one is its eyes, and the short one is its nose. It also has a thick belly foot. It is a mollusk. It will stretch and contract when it rises, leaving a wet and sticky mucus. If you put it in your hand, you will feel very cool.

Snails are generally timid and will put their heads away when touched. Not ordinary. If you leave its food outside its house (coke bottle), it will keep hitting the bottle cap. No matter how hard the bottle cap is, you should go out to eat vegetables. Once, I played a prank on it with a ruler. As a result, it was not afraid, but held its head high and its tentacles kept waving, as if unconvinced. I think it's funny, you little guy. Can you fight me? Hum, please eat my old grandson now! I picked up a pencil, imitated the Monkey King's appearance and struck it. Who knows that the snail retracts its head for a while, then sticks it out, holds its head high, and its tentacles stand upright and motionless, as if preparing for confrontation. I let out a cry, threw down my pencil and ran away in frustration.

I took it.

Snail Grade 4 Composition 2 There lived a little snail by the river in the forest. Today, the sky is clear in Wan Li, and the little snail is walking leisurely by the grass. Suddenly, a bird flew from a distance, and the little snail was trying to see the beautiful scenery! Seeing the bird flying, he asked, "Bird, do you know where the scenery is the most beautiful?" "I know, the scenery at the top of the mountain is the most beautiful!" The bird said, "The sunrise, in particular, is magnificent and magnificent, which can hardly be described in words." "Really? I really want to climb to the top of the mountain to watch the sunrise. " Said the little snail. The bird said, "You can only climb half a meter at most in a minute. How can you climb the mountain? " ? Hehe, you can't go to the top of the mountain to watch the sunrise! "The little snail was very angry and said," I must see the sunrise on the top of the mountain! " "

The next day, the little snail packed his things and set off for the top of the mountain. The mountain is really high, as if the top of the mountain is connected with the sky. Along the way, many animals asked him, "Little snail, where are you going?" The little snail said, "I'm going to the top of the mountain to watch the sunrise." Everyone said that he was daydreaming. The snail walked and walked, and finally climbed halfway up the mountain. At this time, the little snail was very tired. Ready to give up, but at the thought of the beautiful sunrise, the little snail made up his mind to climb up. Climbing and crawling, the little snail experienced many difficulties, and he saved the day. Climbing and climbing, I don't know how many days passed, but the little snail finally climbed to the top of the mountain and saw the sunrise at the top. The sunrise is really beautiful. Clouds float in the air layer by layer, just like a sea of clouds. When the sun rises from the sea of clouds, the whole world suddenly lights up. The sea of clouds turns into a rosy cloud in the sun.

The little snail can't help feeling: "Although the mountain is really high, I believe where there is a will, there is a way." If all snails can persist like me, they will definitely see this beautiful sunrise. "

That is an unusual snail with a "bread and butter" on his back. In the afterglow of sunset, its "bread and butter" will become "pineapple bag". It has a "fragile" body, but it can move something bigger than itself, which can be described as strong as an ox.

It moves every hour. It is still in a corner full of leaves in the morning and moved to the wall at noon. As night fell, the naughty little snail built a nest on the roof. It must want to say "Little Snail Moving Company at your service!" "So I built a company for it-Snail Moving Company.

This is serious. A day ago, it had to move for others (actually itself) about 5-7 times. I think it must be called "Best Employee Award". I always sweat at night, because the requirements of "guests" are super weird. Some want to live on the wall, some want to live in the corner, and some even want to live on the roof. At its snail speed, it is very strange to meet these requirements of "guests" without being exhausted, so every time it completes a task, it has to lie there for a long time before it can start the next task.

He has a strange temper. I gave him leaves and he didn't eat vegetables. I gave him water and he didn't drink water. It seems to say, "I am a local tyrant, please give me a plate of beef and a bottle of wine!" " But I don't want my snail to be the first carnivorous snail in the world.

My snail is the boss of a moving company. He is hardworking, but he is eccentric and always wants to be different.

On a hot summer day, the little snail crawled forward with a heavy hard shell on his back. It's going to climb a big tree in front to cool down first. The sun scorched the earth. The little snail had to carry a heavy shell and endure the scorching sun. When it crawled, it gasped. At the moment, he regrets not listening to his mother and staying at home, but he must come out and find friends to play with.

At this moment, a big cock came by the roadside. The cock couldn't help laughing when he saw the little snail in pain. The little snail was very angry and asked rudely, "Hey, what are you laughing at?" How boring! Hearing this, the rooster flapped his wings and smiled more happily. The little snail was angry and said angrily, you big cock, it's immoral. I'm so tired from climbing that you laugh at me! The rooster said, "I laugh at you for being so stupid!" "It's ugly and slow to carry such a heavy shell on such a hot day. Aren't you stupid and funny? " Said the rooster, with a sly wink.

The little snail suddenly realized, "Yes, why didn't I think of that?" Suddenly, my mother's instructions sounded in the snail's ear: "This shell can protect us, and we have to carry heavy things." The little snail then said repeatedly, "No, no, I can't lose this shell."

The rooster frowned, but immediately put on a smiling face and said, "Alas, little snail, are there any bad people in such a hot day?" Everyone is hiding at home to cool off! Just passing by, I saw you carrying such a heavy shell and walking hard, so I wanted to remind you in good faith. Otherwise, you will never walk under that big tree tomorrow. "

The little snail thought about it, thought what the rooster said was reasonable, and slowly climbed out of the hard shell. He suddenly felt much cooler and his actions were much easier. But it didn't walk much. The hot sun soon dried the mucus on it, and it felt thirsty and dizzy. At this time, there was a sneer from the rooster. The little snail realized that his disaster was coming, but he was unable to climb back into its hard shell. The cock swallowed the snail at once.

The cock flapped its wings proudly and walked away triumphantly. There is only a small snail's shell left on the roadside, as if to tell everyone that sweet words can't be trusted, so keep a cool head at all times.

Snails crawl very slowly on their stomach feet. Test the crawling speed of snails on different materials, and prepare glass, tiles and cardboard. First, put the feeding snail on the glass, put a square next to it, and tie a small piece of apple with thin thread to lure it. The food is about 5-6 cm within the snail's range. After a while, the snail came out of its shell and found that the apple was crawling towards it, gently pulling the thin line parallel to the edge of the ruler, so that the snail could only see and smell but could not eat the apple. The hungry snail had to climb along the ruler to eat the apple. Taking the tail of the snail's abdomen as the starting point and the end point, after 60 seconds, the crawling distance from the ruler is 12 cm, and the calculated crawling speed is 0. 2 cm/sec. Do the same test on tile and cardboard, and the crawling speed is 0 respectively. 15cm/s and 0. 1 cm/s Snails crawl at different speeds on different materials, and glass climbs faster than cardboard. Analysis reason: the glass is smooth and wear-resistant. Observation conclusion: Snails do crawl slowly.

Abdominal foot movement and uniform crawling

Observing the three test experiments, although the speed is different, it is found that the speed remains the same during each crawling process. The crawling speed of snails is directly related to the movement of gastropods. Observing the gastropod of the crawling snail from the back of the glass, we can see that the gastropod muscles contract from back to front, and at the same time stick to the surface of the object to prevent it from sliding backwards. When contracted to the front, the ventral foot is released and the snail can fully extend and slide forward. Abdominal foot muscles contract in waves. After observing for a long time, it was found that the contraction frequency of the wave type was constant, and the snail crawled on the arm, and the rhythm of its movement was always the same, so as to judge that the movement of the abdomen and feet was uniform. The results of reasoning test show that snails do crawl at a constant speed.

I have a lovely little snail. I met my mother-in-law's garden in the countryside last summer and brought pea seedlings to our home. Because he comes from his mother's hometown, we like him very much and named him "Xiaoxiao".

Mix seems to belong to "youth". Its body is pink, its shell is spiral, its color is light khaki, and there are some yellow and black markings on it, like gems embedded in it, which are very beautiful. As long as you gently touch his eyes with your hand, his eyes will shrink back quickly. It's really timid and pleasing.

I found a glass bottle and made him a sunny hut with a plastic cover with a hole in the roof. Mix deserves to come from a vegetable garden. Her favorite foods are bean sprouts and cabbage leaves. Every day I will give him fresh leaves, and at the end of the day, the leaves are covered with traces he has chewed. I have always had a question: how can you eat so much a day when your mouth is as small as the tip of a needle? I decided to take a closer look.

On Sunday, I got up early and found Mix curled up in a shell, hiding under the roof. He always likes to stay there, maybe it is opaque and makes him feel safe. I washed water on its shell to wake it up. Slowly stick your head out of the shell and let the warm sunshine shine on you. I brought some clean leaves, and he opened his mouth and soon ate several serrated holes. It took Baidu a while to know that the snail has a serrated tongue with more than 26,000 teeth in its small mouth! Seeing this information, I can't help but be surprised. Little snail is actually the mollusk with the most teeth in the world, which makes me admire him a little!

Blink of an eye, it's summer again. Xiaoxiao often moves on glass bottles recently. I made an agreement with him that when I went to my mother-in-law's house during the summer vacation, I would take him back to the vegetable garden and let him live freely.

Tortoise and snail are good friends. One day, the snail found the words "snail is an idiot" written on his desk. The snail wondered and thought, "Who is so annoying and scolds me? Yes, it must be a turtle. Is the only person who has been to my house recently. Hum, I want to break up with it! "

The snail climbed to the turtle's house in one breath and shouted at the house, "You ungrateful turtle, come out!" " The tortoise quickly opened the door and said, "Brother Snail, what are you?" ... "Before the tortoise finished, the snail rushed up and beat the tortoise black and blue. The snail said angrily, "We are no longer friends! ""The tortoise asked puzzled, "Why?" The snail said, "How do you know!" Say that finish and left. "

The next day, the snail went to a friend's house to play and met a turtle on the way. The tortoise seemed to forget what happened yesterday and still greeted the snail, but the snail ignored it and just went on his way, so the tortoise followed the snail. Unconsciously, they came to the saltworks, and the snails also went to the saltworks. The tortoise saw it and shouted, "Snail! Don't go there, you will become a pool of water! " But the snail didn't listen to the advice, thinking that the tortoise must be up to no good and went straight to the salt bar. It said, "Nothing!" "When it finds that it wants to go but can't walk, it's too late. The snail's body has begun to melt into water!

The snail watched his body turn into water gradually, and said regretfully to the tortoise, "It's all my fault, I didn't listen to your advice ..." After saying this, the snail turned into a pool of water on the ground.

Snail fourth grade composition article 8 "Snail snail doesn't worry about rain, people have umbrellas and I have big shells." Who is talking about me? It turned out that children were making up children's songs for me!

No one carries a big shell like me every day except Brother Turtle, who has the same personality as me. This big shell is like a big mansion for people, warm, comfortable, warm and beautiful. It is spiral, like a mini wormhole. I took it all over the country and made good friends in various places. I don't want to be like those "neets" who ask for money with their mouths open and eat with their mouths open. I am an ace snail with noble blood and self-reliance.

My antenna also has many uses. It can stretch freely. If I see food, I won't gobble it like a lazy sheep. I will use my 360-degree "food tester" to test it many times, and then chew it slowly for six or seven minutes after making sure it is non-toxic and harmless. I remember grandpa said, "Look before you leap, and be careful to sail for thousands of years."

My stomach is the most useful organ in my body. Once it's gone, I can't walk anymore, like the legendary "vegetable". It is as soft as a paper tiger, but even so, even if there are small thorns in front, I will not go around it, but rush forward without hesitation. It can also secrete a kind of mucus, which can make me fly over the eaves and walk on the wall, just like learning lightness skill. When I walk, I will leave obvious marks, so that I won't get lost and I can go back the same way.

Stop it! Stop it! It is raining! I'm going home to pack my clothes.

I have five small snails. Because they walk very slowly, I call them "lazy people".

I like watching snails very much, watching the way they walk and looking for food. I fell in love with the little snail over time. So I caught five snails and raised them.

One day, I went to see the little snail and found the snail's head in its shell, motionless. The hard shell seems to be covered with a layer of white latex. I thought they were dead, but I'm still sad.

Maybe I don't want to lose these five "lazy people" like this. I didn't know that the snail was not dead until I checked some information. They just need to live in a humid environment. So I gave them some water and food.

Snails often eat vegetable leaves, among which cabbage leaves are the most eaten. Look, after a few minutes, the little snail began to eat happily. At this time, they don't have a "lazy", their heads stick out of their shells and crawl forward like soldiers. It can also attract objects to metal like a magnet, and it will leave long mucus and occasionally "poop". After eating, it quickly climbed under the leaves. It turns out that it has slept in.

I like these snails. They not only enriched my after-school life, but also taught me the knowledge of raising snails.
