The little ant moved me
This morning, I went to conquer Mathematical Olympiad with great interest.
All of a sudden, a question I have never seen is like a mountain blocking my way. I think about it, but I still haven't done it. It's like walking into a dead end. My head is a little sleepy. I had the idea of giving up this Mathematical Olympiad problem, but I was not willing to.
"Forward or backward?" I'm in a dilemma, helpless. "Adjust first." I said to myself. Then, I took a book out of the bookshelf, read it and turned to the story of a general.
A general, a small ant, a high wall, this group of living patterns, reflected in my eyes, deeply attracted my eyes, I can't wait to read the story in one breath. Close the book, I am very moved, a little ant moved the general, the general's action moved me. The story goes like this:
Due to the rainstorm, a general was defeated in the battlefield. Hiding in a manger, he found an ant carrying a corn on his back and climbing over a wall. Once, twice, three times Sixty nine times, ants always fall off the wall. The seventieth time, a miracle appeared, the little ant actually crossed the tall wall. When the general saw this scene, he was shocked and inspired. He reorganized the army, fought hard, and finally turned defeat into victory, achieving great achievements.
After reading this story, the tall image of a little ant is deeply imprinted in my mind. Facing a tall wall and carrying heavy bags, the little ant still perseveres in climbing over it. It won't succeed until the 70th time. The first 69 failures have established its confidence and determination to overcome difficulties, that is, "don't stop until it reaches its goal", the kind of indomitable and courageous spirit The spirit moved me and inspired me.
I closed the book and looked at the Mathematical Olympiad book on my desk. "This is a wall, this is a mountain, I am the little ant, I must cross this wall." I made up my mind. Open the book of Mathematical Olympiad again, clarify the thinking, analyze step by step, and find the right entry point. Ten minutes later, I felt a long sigh of relief, and finally I overcame this Mathematical Olympiad problem.
Close the Olympiad Mathematics book, my mood like the waves of the sea for a long time can not be calm. Today, I understand a truth: difficulties are not terrible, the magic weapon to overcome difficulties is not to give up, not to abandon, perseverance.
2. The self narration of ants
I am an ant. I've lived in the ant family for a long time, but those people didn't pay much attention to our huge ant family, because we are too small.
Let me tell you what we look like first. We ants are very small. Our bodies are long, black or brown. Our head is big, with a pair of compound eyes and long antennae. Our abdomen is oval. In spring, the queen and the male will grow wings!
It's hard to say about our age. Let me tell you about our family history.
Let me ask you a few questions first. How many species of ants have been found? How many of them are there? Ha! I can't answer it. Let me tell you, there are 11000 species of ants that have been found, about 1, followed by 15 and 0.
We have very few ant fossils, because we are too small to form fossils easily. But we ants are the most successful animals ever evolved. The best fossils that have been found are in amber, which is transparent. Ants are enclosed in amber, which is often very complete and three-dimensional. You can see the whole picture of ants. To be honest, the ant enclosed in amber described below is the first one to be found, which was formed in the Cretaceous period of 138-5 million years. To be honest, I was very excited when scientists found the amber, because it was my grandfather's grandfather's grandfather's Grandfather. But I showed off to other ants for a long time because of this discovery.
Let me give you another piece of news. When we ants came to this world, it was a time when dinosaurs flourished. In other words, our ancestors were witnesses of the extinction of dinosaurs. They knew how dinosaurs disappeared from the earth. Unfortunately, my ancestors have been sealed in amber. I think you can imagine that the giant dinosaurs fell down one after another, but the little ants got into the hole safely.
Well, that's all. I believe you have learned something about the history of ants. But there are still many things I didn't say, but it's up to you to explore!
The secret of ants
Today is Sunday. I'm watching TV in the living room. All of a sudden, I saw a little ant crawling around the dining table, and soon found a small piece of bread. Although this piece of bread is only the size of a grain of rice, it is a huge thing in the eyes of the little ant. It happily revolves around the small piece of bread for three times and then leaves. I followed it curiously and found that the little ant went under the crack of the door. I think: that may be its nest. After a while, a large number of ants emerged from the nest and came to the small piece of bread. They worked together to move the small piece of bread back to the nest. I think: this large number of ants must be that little ant. When it found the food, it called a large number of ants to carry the bread back to the nest. I wonder how far away it is for ants to go from the nest to the dining table! How can the little ants not get lost?
Around this problem, I consulted a lot of materials, and finally I knew the secret.
It turns out that the visual organs of ants are very sensitive. The scenery on the land, the position of the sun and the sunlight reflected from the blue sky can be used to identify the direction of returning to the nest. In addition to relying on the eyes, ants can also recognize the way according to the smell. Some ants will leave a special smell in the place they climb. On the way home, as long as they follow this smell, they will not lose their way. Some ants, although they don't leave a special smell in the place they climb, are very sensitive to the natural smell on the way back and forth, so they won't get lost.
Since ants identify their direction by smell or scenery, there is neither blue sky nor sunshine in my home. Ants may identify their direction by smell when they look for food in my home. So I did an experiment.
I deliberately put a small piece of bread on the table. In a short time, an ant came to the table. When it found the bread, it was ready to go back to its nest and ask its partner to carry the food. I took a pencil and drew a line on the way the little ant was going to pass. When the little ant got there, it was in a mess. I saw it bumping around, lost its way, and finally crossed the line, found its original smell, and returned to the nest. Through this experiment, I finally understand that ants can identify the direction by smell.
It's interesting to explore the mystery of ants!
The spirit of ants
Through the transparent container, I observed two ants: they may have just arrived at this place, unfamiliar with the surrounding environment, scurrying around in the container, still crawling on the bottle wall, as if they wanted to leave this place. Look! How interesting! Two ants bumped their heads together because they were walking too fast. After a while, they seem to get used to the environment, no longer move, but quietly lie in a corner to rest, but still curious to swing tentacles, like a naughty child.
These ants will also dig beautiful 3D tunnels in the nutrition glue. Every day I look forward to the ants digging a beautiful tunnel as soon as possible. Every day after school, I go straight to my room to see the "digging progress" of the two ants, but I am disappointed every time. The nutritive glue has not changed at all, it is still the same, and the ants are still lying in that place, lazily motionless. Two days later, there was no movement. I was so angry that I almost threw the ant away. Mom told me, "haven't you heard of it? "If you want to be quick, you can't reach it." if you observe for a while, it will always dig. " So I waited another two days, but it was the same. I'm in a bit of a hurry. I'm looking everywhere for a "panacea" for ants to dig tunnels quickly. Some students said to poke two small holes about 2.5 meters deep on both sides of the nutrient glue to let the ants climb in along the hole. Some students also said to drop some honey in the hole to let the ants smell the fragrance and climb in, but there was no significant effect. I decided to let the ants dig the tunnel by themselves.
Finally, my efforts were rewarded. In the morning of the fourth day, the ant finally dug the tunnel. At that time, my happy mood could not be described with any words. Two ants are drilling in the tunnel, working hard. The big ant bit a piece of nutritive glue in the tunnel, climbed out of the tunnel, and put the nutritive glue in a corner to continue to work. It's really interesting. A week later, the tunnel has been dug a lot, crisscross, full of artistic sense, really beautiful!
Ants, what a wonderful little animal. If you think about it, don't we lack the spirit of ants? Diligence, unity and loyalty are the nature of ants, and we humans should learn from them. Ants have taught me a lot about life in these days
5 ants
I have a hobby since I was a child. I like to observe the life of ants. So far, my interest has not decreased. There are many kinds of ants: black, brown, light gray I like the little brown ants best.
They work hard all day and none of them is lazy. Once, I accidentally dropped a grain of rice on the ground and just wanted to pick it up. All of a sudden, a little ant came over, bit it with its mouth, rowed six tiny feet, and crawled forward step by step, very slowly. At this moment. To a group of and it is very similar to the ants, we unite, work together, and finally the rice slowly into the hole.
Once, I saw a "miracle". It was at noon last Sunday. I squatted under the eaves and used some steamed bread residue to attract an ant. It happened that it was small and brown, with six tiny feet. I saw it go to the front, with the forehead of two small almost invisible tentacles touched a few times, and then with his mouth biting steamed bread residue, head high, walking very fast. Who knows, disaster came, suddenly a giant, straight from, snatch the small ant prey. This big thing is a big black ant. It dances its thighs, opens its mouth and fiercely grabs the steamed bread residue. The little ants are not afraid of each other. After a few bumps, they twisted together and started to fight. I'm really worried that the little ant can't beat it. Because the body of a big ant is two or three times bigger than that of a small one. The big ants open their teeth and wave their claws, while the small ants fight tenaciously. This fight for a while, the ant suddenly ran away, the action is extremely fast, thin feet row very fast. "Are you afraid?" I said contemptuously to myself. Who knows, the situation is just the opposite. Soon after the ant runs, there are three same brown ants. It turns out that this ant called its companion just now. Three as like as two peas, one after two. Line up to fight with the big ants. The battle is hard to break up. As a result, a small ant climbed up on the big ant and took a vicious bite. The pain made the ant turn over and feel embarrassed
