Each kind of knowledge is divided into four parts: main content, extended knowledge, little doctor's garden, and anecdotes, such as: Why do piglets compete to eat sow's milk? You may find that pigs seem to be fighting for milk. In fact, the pig is looking for the last place to drink milk. They drink milk in the same place every time. This is knowledge that I have never known.
And dinosaur fossils. Dinosaurs have long been extinct, but their fossils are still there. Scientists are not afraid of difficulties, digging up dinosaur fossils from the ground again and again, studying the living habits of dinosaurs in ancient times, and letting us know more about the distant past. How amazing they are! Just like our study, we should work hard, take time and persist. If we can't do it, we will only fail. As the saying goes, "failure is the mother of success". We can fail, but we must not be discouraged, or we will give up all our previous efforts. Many famous sayings teach us to be diligent. Diligence can succeed, and diligence can give us the golden key to open the door of knowledge. There is a lot of knowledge in this book that we don't know, such as why the power of seawater can generate electricity, which I still don't understand, but scientists have long known. Therefore, anything you don't understand must be curious, and only after curiosity can you understand. Of course, it is not easy to understand it.
My ideal is to be a scientist and invent instruments that can make people do things and work conveniently. So from now on, I will study hard, make progress diligently, be a good discoverer and persistent person like a scientist, discover unsolved mysteries, be a useful talent and contribute to creating a beautiful home.
2. After reading three articles about animals and writing articles about animals, you must read 50 words. After reading the essay "Kind Animals and Cruel People", I can't help but feel deeply.
The kindness of animals and the cruelty of people now fully illustrate a problem: hunting. People often kill some precious animals for money and then sell them for money.
These animals can only wait for death, silently begging and longing for their only life at the gunpoint of the upper class, which is very common in some places where there are many precious animals. Let's think about how many animals have died since ancient times.
Antelopes, snow chickens, Tibetan sheep and so on, for them, this life is not peaceful. They dodged the hunter's quick bullets and ran away.
Begging and hoping for that gun, the hunter can relent and let himself live. There was even a Tibetan-aged sheep who begged the hunter not to shoot for the sake of the baby in his belly, but the cruel hunter ignored it. He would do anything for money and meat.
Have you ever heard the whine of animals before they are killed? Have you ever heard of nocturnal animals? They've had enough, really enough.
3. Write a composition of people, write a composition of scenery imagination and describe animals. After reading it, each has a dream of Lijiang River.
"Guilin's landscape is the best in the world, and Yangshuo's landscape is picturesque." I went to the picturesque Guilin in the summer vacation.
Guilin really deserves its reputation! I sat on the boat and quietly looked at this fantastic Guilin. Look, how beautiful the water in Guilin is. You can see the sand and stones at the bottom of the water at a glance. Look, there are some lovely little fish swimming happily underwater, and conch moving slowly under the water. The mountains in Guilin are not inferior. The walls are cut, and the peaks are listed, which is full of momentum. Green mountains overlap, just like the ups and downs of the sea, surging and magnificent. It is really "above the blue waves, people travel in the picture world".
When the boat was sailing slowly, we saw the famous Elephant Trunk Mountain in Guilin. A big hole in the middle of Elephant Trunk Hill just separates the nose from the body. A living elephant appeared in front of my eyes. Its nose sticks into the water as if to drink water. The water in Lijiang River is green. Against the fragrant hills, the Lijiang River is as green as a glittering jade. The Lijiang River is quiet and can only see the microwave generated by the ship. It's amazing in every way. Without mountains, boats and trees, it seems that you can't feel the existence of Lijiang River.
We also saw nine horses drawing mountains. Under the guide, we saw nine horses. Many people are amazed at the nine horses. We also saw a camel crossing the river. Camels are so similar. A camel is preparing to cross the river by the Lijiang River. It is really cute. We also saw Fubo Mountain, Diecai Mountain and Tashan Mountain. ...
The Lijiang River in Guilin is beautiful, and the karst caves in Guilin are also amazing. Look, this is a live butterfly. It's a group of dragons welcoming guests. There are also beautiful crystal palaces and cash cows. The caves in Guilin are really great.
Guilin, a beautiful city, shows us the best example of the beauty of caves and rocks. Guilin is really beautiful!

4. After reading the composition of small animals, 350 words of cute rooster.
There are two photos on my wardrobe. Looking at these two photos, I think of two cute little cocks I raised before.
That summer vacation, my mother and I bought two cute little cocks. They are furry and feel like a ball of wool. Because one of their mouths is red and the other is yellow, we call them Xiaohong and Huang Xiao.
When Xiaohong and Huang Xiao were young, Xiaohong was more powerful. Wherever Xiaohong went, Xiao Huang followed, and Xiao Huang followed. When they grow up a little, whenever I let them out, they will start work first, but every time Huang Xiao lowers his head and dares not resist, while Xiao Hong proudly holds his head high.
When Xiaohong and Huang Xiao eat, Xiaohong always throws his food aside and stares at Xiao Huang's food. Sometimes he can eat Xiao Huang's food in one bite. When Xiao Huang didn't eat, he wanted to eat the food that Xiao Hong threw away, but Xiao Hong wouldn't let him, so Xiao Huang was helpless.
Once, after I put them out, I forgot to bring them back. It took me half an hour to remember. However, when I went down, I only found Xiao Huang, but Xiao Hong couldn't find it. I searched for it for a long time and finally found it in the bushes. It's covered in blood. When I brought it home, I found that it seemed to be blind in one eye. Later, I learned that Xiaohong was caught by a wild cat downstairs and almost eaten by a cat.
A month later, a miracle appeared. Xiaohong's eyes are good for no reason.
In the second summer vacation, Xiaohong and Huang Xiao grew up, so they couldn't raise them at home, so they had to be raised by their uncles.
Two years later, my uncle told us a bad news, saying that Xiaohong and Huang Xiao were too courageous to provoke the German shepherd, put their necks into the dog pen and pecked at the German shepherd's head, and they were killed.
Now, when I can't see other people's chickens, I will think of my two lovely little cocks-Xiaohong and Huang Xiao.
This is absolutely original. I just wrote it. Please believe me. Can you adopt me?
After reading Chekhov's Distress, I deeply felt the misery of people living at the bottom of society.
Distress tells the story of a rickshaw driver Jonah pulling a rickshaw on a winter night. Jonah's son died in the hospital this week. His old man has lost his wife, and now he is lonely and numb with grief.
He received several groups of passengers, and tried to tell them his distress and grief several times on the way, but they scolded him because people thought he was absent-minded. Late at night, he went back to the garage, but he didn't even earn money to feed the horses oats.
Darkness, loneliness and sadness returned to him, and the cold weather made his heart even colder. He gently stroked his faithful little mare and told all this ... Jonah, the driver, was just one of the people in Qian Qian who lived at the bottom of society and had a miserable fate.
These people are poor, helpless and miserable. They can't enjoy life, and they run for it every day.
They lead a hard life and often worry about the next meal. These people work hard for a living. Who can they talk to about their troubles? How many people really understand them, care about them and help them? People living at the bottom of society think that life is unimaginable for us ordinary people, and they have more troubles than us ordinary people.
In fact, no matter which society is prosperous or backward, there are people living at the bottom of society, and their fate is equally tragic. After watching "Distress", I remembered the old people who lived by collecting garbage in the street.
These old people are in rags, hunched over and carrying heavy garbage bags. In summer, they walk in the streets in the hot sun and in winter, braving the cold wind. Sometimes they rummage through dirty trash cans to see if they have anything to sell, and sometimes they follow pedestrians to pick up cans and packaging bags they have left behind.
These old people may be childless, abandoned by their children, disabled or uneducated. They don't have much labor force, so they can only live this poor life and live at the bottom of society.
But also be looked down upon and despised by people. They have been depressed for a long time. To whom do they tell their troubles? Some of them are suffering from the grief of losing their children, some are suffering from the desolation of being abandoned by their children, some are suffering from the inferiority of the disabled, and some are suffering from the regret of "being young and not working hard" ... These people all hide their worries in their hearts, can't find anyone to complain about, and have no time to grieve for spring and autumn, because the next meal is not decided because of the slowness.
Jonah, the coachman in trouble, has a miserable life, but he is not alone.
6. How to write the self-report of the giant panda in the composition about animals?
I am a national treasure panda. My head is round, my tail is short, and my whole body is round. Don't think my eyes are big. In fact, there is a circle of black hair around the eyes and small eyes are hidden in the middle. I only live in the ravine of the Qinghai-Tibet Plateau in the upper reaches of the Yangtze River, where pieces of bamboo grow, especially my favorite arrow bamboo. I like to keep eating every day. Eat 12-38 kg of bamboo at the end of the day. It's amazing! My ancestor panda existed as early as 2-3 million years ago, so I am also called a "living fossil".
Originally, our family has been very happy, and you like our innocence very much. However, I gradually find that life is getting harder and harder. Because of deforestation, the territory we live in is getting smaller and smaller, disappearing at the rate of 2.5 square kilometers per year; Because I only live in China, many bad guys arrested us and smuggled us abroad for exhibitions ... Such a hard life made me haggard. When I was looking for food everywhere, I was hungry and thirsty, and I was afraid of being caught. Fortunately, the country has designated us as a national first-class protected animal, and the area where we live has been designated as a national nature reserve. Our happy life is back, and we are even cuter. Last April, our golden couple and Yuan Yuan went to Taiwan Province on behalf of the mainland, expressing the desire of the people on both sides of the Taiwan Strait for an early reunion. This is the most glorious thing in the history of our family. Looking back now, I am still very excited!
The new year is coming, and I have a new year's wish: put on a beautiful makeup and take a beautiful color photo.
Self-report of giant panda
I am a giant panda, one of the most precious animals in the world. My home is mainly in some mountainous areas in Sichuan, Gansu and Shaanxi provinces, and the number is very small. Belonging to the national first-class protected animals, it is called "national treasure". I was not only chosen as the emblem by the World Wildlife Federation, but also undertook the task of "peace ambassador" for a long time. With the friendship of the people of China, I traveled across the ocean and made friends abroad, which was well received by people all over the world.
April and May are the breeding seasons of our giant pandas every year. At this time, parents will live together, but after May, they will go their separate ways. My mother is 4-5 months pregnant and is anxious to find a tree hole or a stone hole as a "delivery room". I was only about150g when I was born, which is equivalent to one thousandth of my mother's weight. But after one month, the weight can reach 2 kilograms, and after three months, it can grow to five or six kilograms. My mother often holds me in her arms and caresses me gently. When she goes out, she often holds me in her mouth or carries me on her back, kissing me and being inseparable. When I was five or six months old, my mother began to teach me the skills of climbing trees, swimming, bathing and peeling bamboo. It was two years before I left my mother and began to live independently.
When I grow up, my body is fat and soft, and my limbs are stout. My body length is about 1.5m, my shoulder height is 60-70cm and my weight can reach 100- 180kg. In particular, that pair of figure-eight dark circles, just like wearing a pair of sunglasses, is very attractive.
My ancestors were carnivores, but now they prefer vegetarianism and mainly eat arrow bamboo for a living. As an adult, I eat about 20 kilograms of fresh bamboo every day. Sometimes I go to the bamboo forest with "quick" to catch a good meal of bamboo rats, and even swagger into residents' houses to steal food.
I am withdrawn, like to live alone, stay overnight, have no fixed address, and often move with the change of seasons. In spring, I usually stay in the alpine bamboo forest above 3000 meters above sea level, move to the shady slope with fresh bamboo branches in summer, and move to the warm sunny hillside about 2500 meters in autumn to prepare for the long winter.
My family is very old. There are only a few left, and we have become a precious "living fossil" for scientists to study biological evolution.
I am a puppy. I was born pink, and I am a landing dog. I was separated from my brothers and sisters before I opened my eyes. My ears vaguely heard the owner of the kennel say, "This is a landing dog, which is difficult to keep. It only eats white rice. It's a pity to throw it away. If you don't throw it away, you'll have to eat white rice again! " I looked up trembling (although I can't see it, but I have a good sense of direction), but I heard the hostess say, "You are very smart, stay! Someone will buy it when they grow up. " I survived, escaped and went back to my mother. After a few days, my eyes opened, and my eyes were full of curiosity about the world. I saw many things and my brothers and sisters. They grew very strong, and one was held under my stomach by my mother, but they were soon squeezed out by other dogs.
So I only eat a little every day after everyone finishes eating. Seeing that everyone has grown up, I am very young.
7. How to write a composition about animals First of all, if you want to write a composition about animals, you should observe it carefully. Observation is the source of writing, you should grasp the characteristics of animals to describe and describe them. For example, to write a kitten, we should carefully observe its coat color, the way it eats and the way it sleeps. What you can never write is: a pair of round eyes, a shiny hair ... because these descriptions apply to any animal. This is not good. We must find out its "personality characteristics" There are no two identical leaves and no two identical cats in the world. Watch carefully what you write about cats. Second, we should write about animals in various ways, not just the animals themselves. For example, we can reflect the characteristics of animals through their living habits. Cats like to go out at night and sleep during the day. When they go out, their job is to catch mice, thus eliminating pests for human beings. The contribution of cats to mankind is written from the side. They are friends of mankind. Third, they are clear, organized and hierarchical. Fourth, you can use various rhetorical devices in your composition, such as metaphor, exaggeration, personification, etc., which can make your animals more vivid and vivid. Getting high marks is also the highlight of the article. Fifth, the beginning and end of the article should be concise, and the article should come straight to the point and attract readers.
8. How to write "my dog" in the composition about animals?
My family has a lively puppy. It has snow-white fur, and only its forehead is light brown. It has a sharp and long mouth, sharp teeth and claws, a red and wet nose, triangular ears and bright big eyes, just like a snow white. It is very beautiful. I gave the dog a name, Huanhuan.
Huanhuan's personality is the same as the name, very cheerful and lively. Whenever I come home from school, Huanhuan will suddenly rush out, wander back and forth between my feet, and even jump on me and ask me for a hug. After that, my mother found a small table we didn't need, put Huanhuan on it, and it was almost time for school. Huanhuan sat on the table and looked up at the school gate. Those melancholy eyes seemed to say, "Little master, when will you finish your studies?" I'll wait at home for you to come back and play with me! "After school, the students lined up and walked out of the school gate. Huanhuan looked at them one by one, as if looking for my little master. When it saw me, Huanhuan could only wag its tail, and its four little feet kept stomping around, very excited, as if to say, "Little master, you have finally come back, I have been waiting for you for a long time! "It's a pity that it is on the table and can't come to play with me.
Now, Huanhuan has grown up and is more lively than before. Every time I sweep the floor with a broom or mop, I will pounce on her, hug her and throw my head around so that we can't pull it out. A broom was bitten by a puppy before. Now we hold the broom high. The puppy saw it and wanted to jump up and bite. We were all stunned when he jumped down. I didn't expect the puppy to jump so high. It's really amazing. What else! Dad hung a cotton rope on the wall. The puppy saw it, jumped lightly, took a bite and kept pulling down. The cotton rope went up and down for a while. Very interesting!
9. Compositions and articles about animals (model essay) Today, I went home happily and saw two lovely little squirrels.
Their delicate little faces are inlaid with round eyes and triangular ears. They are all black, but there are some white patterns.
One of them is Qiqi and the other is Jingjing. Squirrels are interesting when they eat. They always sit on the upper body, holding food in their hands and putting it by their mouths.
When eating corn, they take the corn kernels off with their hands and feet, and eat them slowly one by one, eating only meat and not skin. And they eat a little here and a little there, which is really a portrayal of monkeys moving corn.
Little squirrels are more interesting when they sleep. One of them lay like a puppy, and the other curled up like a hedgehog. All you have to do is walk over and make a noise, and they will wake up immediately.
"They are so vigilant!" I always tell my mother that. Mother always replied, "Because nature is the place where the fittest survive."
Squirrels will be eaten if they are not careful. ""Isn't that little squirrel sleeping badly? What a pity! " Mother always smiles faintly.
Soon after, Jingjing slipped away because of my mistake. Only Qiqi is left.
He squatted there every day, eating very little, just waiting there. "If only Jingjing could come back!" "Do you know why Jingjing runs?" Mom asked me with a smile.
"Because of my carelessness." "Wrong, because Jingjing needs freedom and wants freedom."
A few days later, I gently opened the door of the cage. Qiqi stayed for a while and then ran away.
My mother came over and looked at me. I smiled and said, "Qiqi needs freedom, too." [b] Great love [/b] Spider spinning has a great significance in his life besides hunting, and that is the continuation of life.
There is a red spider in Africa, which is tightly wrapped in egg bags with sticky spider silk. The female spider guards the egg bag all day, waiting for the birth of the baby spider.
About a month later, the egg bag cracked a small hole and the little spiders climbed out one by one. These little spiders are born to eat.
The mother spider laid a dozen food balls, enough for the little spider to eat for three days. Three days later, the little spider grew up a lot and began to shed its skin for the first time.
At this time, the mother spider gathered the little spiders together with her spider thread and then lay on them. The hungry little spider scrambled to climb on the female spider and began to hesitate. But I don't know which little spider took a bite first, and my mother's skin was bitten. Other brothers and sisters smelled blood, a bit like their mother.
After a while, the mother's body was covered with children, and each child had a sharp straw. Hundreds of straws pierced the mother's epidermis and stabbed her body. The mother did not move, so that more than 100 children sucked the liquid in her body and fed it again and again.
The female spider's body is enough for the young spider to eat for four days. Four days later, the little spider grew bigger and bigger, and the mother spider had been eaten up.
The female spider not only feeds her children, but also awakens their hunting nature with her own juice. The female spider willingly served as her child's first prey.
The child learned to hunt by eating his mother. Only in this way can the little spider survive in a harsh environment. People know that female spiders eat male spiders and call her' black widow'.
But people don't know that female spiders eat male spiders not only to supplement their own nutrition, but also for the baby spiders to be born soon. I think both male and female spiders know this. They gave their lives for their children, and it was so painful for the female spider to eat the male spider.
Spiders have a rare love among animals. Rooster: I like a croaking rooster.
It has a crown like a torch on its head. The feathers on his back are like wearing a crimson shiny coat.
The belly feathers look like a golden shirt. A pair of bright and flexible eyes and a sharp mouth, together with the most striking colored tail, look beautiful and powerful.
The rooster stood on the platform in the morning and barked loudly, urging people to get up quickly. Usually, roosters are experts at catching bugs! Although some bugs are alert, they can't escape the rooster's eyes as long as they move.
Once, I saw a bug just crawling out of the grass under the tree for a walk, and the rooster found it. I saw the little cock running under the tree quickly, and with its sharp and slender mouth, it caught the bugs at once, so all the bugs became a good meal for the little cock.
Once when I came home from school, I saw the rooster scratching under the big tree in the yard. I quickly put down my schoolbag and grabbed a handful of rice for it to eat. The rooster had a good time. I don't know whose rooster is coming to compete with the rooster for food.
This angered the little cock, and he rushed up to fight with the big cock. The rooster pounced on him, and the little rooster calmly fought and shrank from the rooster's tricks.
Then, it immediately turned to the back of the rooster, suddenly jumped up, jumped on the back of the rooster, pecked its head, and made it bleed. The cock ran away in pain.
The cockerel won, holding his head high and sticking out his chest. Look, you look very proud. I'm flattered.
I especially like this beautiful and lovely little cock. Little white pigs There are two little white pigs in my family.
They are all white, and their big ears are like two powerful fans, flapping up and down; Long nose, a pair of round nostrils, like two small caves; There is a big mouth hidden under the nose. If you don't look carefully, you won't find a mouth under your nose. There are a pair of unpredictable little eyes and wrinkles on the nose, which really doesn't look good. When the farm is busy, my mother works in the field and asks me to feed at home.
I opened the door of the pigsty and put the prepared food in front of the pigsty. Greedy pigs have sharp noses and the smell has been smelled by them. Before I could pour the pig food into the bowl, they swarmed and spilled a pot full of pig food. Pig food splashed on my face, trouser legs and coat, and I was so angry that I picked up a stick and wanted to hit them.
But as soon as they raised the stick, they cried "wow", as if begging for mercy from me. Looking at their poor appearance, I can't bear to let the stick fall again.
The little white pig grew up and showed his true nature-gluttony and lethargy. Whenever their mother feeds them, they gobble them up.
10. How to write an essay about small animals When he was a child, the monkey chased pheasants and rabbits with his father, so he learned a good skill of climbing mountains. Once a group of wild goats appeared in the mountains, and my father and I set off with guns and dogs. But the day is almost over, and our father and son still have nothing. Suddenly, Monkey King, Monkey King and Wang Dasheng cried. My father walked over and said confidently, "After the flowers, smell the footprints of this wild sheep. I believe you can catch it. Go ahead. " After listening, the dog disappeared into the Woods. After about ten minutes, the dog barked again. We chased into the Woods and ran for a while before we saw an adult wild goat fighting with a dog. That wild goat is really "old bones". It always rushes towards us, and my father and I are forced to step back. You know, dogs are generally loyal. As long as people leave the forest, it always leaves the forest with others. But Flower Dog is also smart! He knew that his father was testing him, because he didn't shoot, so the dog kept biting him with the sheep. When the wild goat turned his head to the dog, the dog jumped up and bit the wild goat's throat with sharp teeth. I saw the wild sheep waved and fell to the ground with a bang. But it still struggled desperately. When the dog bit it, it wouldn't open its mouth until the wild sheep couldn't move any more. Our father and son happily picked up the wild goat and walked home. The dog barked proudly. Measuring lung plating at the beginning of Dan made the monk super lucky.
Another time, my father took me hunting in the mountains, and suddenly a badger hole appeared in front of me. Father asked me to stay at the mouth of the cave with the dog. Then my father picked up some straw, went to a hole, stuffed it into the badger's hole and lit a fire. The badger couldn't stand the strong fireworks and ran away from me. In order to get my father's praise, I picked up a branch and pounced on the badger. But badgers are tough. He looked at me and probably thought I had no problem, so he yelled at me. My heart was pounding, and just when I was at my wit's end, the dog pounced on me, biting the badger's tail and biting it tightly. The badger jumped up and screamed in pain, and suddenly the dog was thrown away. The dog got up without fear, jumped on it and bit the badger in the stomach. At this moment, I saw that brave dog immediately threw the badger down, bit the badger's stomach with Kouga and pulled out his intestines. The badger was in great pain and fought back with his sharp claws. The dog's nose was scratched. When the two animals were fighting again, the father came and shot the badger hard in the head. The badger stopped moving. Flower dog also fell down, licked his nose with his tongue, stood up as usual and posed as a winner.
Later, dogs were not allowed in the local area. Dad thought about it for several days and finally sent the dog to the forest protection team. Let it contribute to the forestry of the motherland.
Although I have lost such a "good friend" now, I still miss it.
Summary of Personal Training for Physical Education Teachers
