Chapter 1: Survival of the fittest in natural selection

With the pursuit of wolves, antelopes can walk as fast as flies; With the pursuit of sharks, swordfish can swim like an arrow; With the pursuit of goshawk, Swift can soar.

In order to survive, antelopes, swordfish, swift and other creatures have evolved ways to deal with natural enemies, so they have survived.

Nature is cruel. In natural selection, the fittest survive. Creatures that can't adapt to the environment will only be eliminated under the cruel jungle law.

Therefore, the mother eagle mercilessly pushed the baby eagle off the cliff a few months ago, because she knew that only under the baptism of the storm, the shadow of death turned into strong wings, and the offspring of Goofy could become the living strong and the proud king of the sky-Goshawk. An eagle that has never experienced a moment of life and death can only become a big chicken. Because of the "cruelty" of the mother eagle, the eagle family can survive under the more cruel jungle law and become the overlord of the sky.

The eagle is like this, so are people? (Tongling Shida Fire Door-Shida Literature www.tl-shida.com)

Growing up in parents' arms, cradles and greenhouses, how should we step into society?

Society is not a cradle, a greenhouse or a charity for poverty alleviation. Although today's economic commodity society is not full of traps step by step, it also deduces the law of the jungle. How can we become strong if we have not experienced the test of blood and tears? Some people who have not experienced the test of wind and rain think that society is also a cradle and a greenhouse. They enter the society ambitiously, but they can't stand suffering and fatigue, and finally they can only be eliminated by society.

As a middle school student, we also have many complaints in our study and life: too much homework and too little rest; Too many books and too little play; Too nervous, too little relaxation. In the face of these difficulties, we should not give in, but face them bravely, adapt to them and even surpass them.

Our lives are in our own hands. No matter what difficulties you encounter, you must learn to survive, learn to face and learn to bear. Only in this way can we go forward bravely in the voyage of our own life and never give up!

Chapter 2: Natural selection, survival of the fittest.

"Natural selection, survival of the fittest", in a word, competition is everywhere. Competition-it is like a rose in the big garden of human society. It has both delicate and fragrant flowers and sharp and hard spikes.

Competition, it looks beautiful.

First of all, it promoted historical progress. However, throughout the history of China, all brilliant and talented times are times of fierce competition. During the Spring and Autumn Period and the Warring States Period, great powers competed for hegemony. If every country wants to survive, it must first be politically enlightened and powerful. On this basis, Gou Jian tried his best to cooperate with the people. Finally, through ten years' efforts, his national strength surpassed that of Wu, and Fuxi was destroyed. Only when Qin's five sheepskins were exchanged for Prissy, Shang Yang's political reform, and Lian Heng of Zhang Yi came to Ying Zheng to dominate the country. Second only to the glory of China. Here we can see that competition has promoted the progress of human history and the development of society. (Tongling Shida Fire Door-Shida Literature www.tl-shida.com)

Secondly, it promoted the prosperity of culture. In all the times of cultural and artistic development, there are many sects and different opinions. For example, in ancient China, Confucianism advocated benevolence, righteousness and propriety, Taoism advocated Taoism and morality, and Legalists emphasized law. They hold their own opinions and a hundred schools of thought contend. China's ideological culture has been greatly enriched and developed in politics, legal system and social life. In the modern new culture movement, culture has been pushed to a climax again through endless arguments among reformists, reformists and retro-ists. Here, we can find that the prosperity of culture needs constant competition.

Then, it also realized the improvement of people's living standards. Looking at today, the competition in all walks of life is fierce, the biggest beneficiaries are consumers, and the people's lives have been improved. In the competition, products from all walks of life are dazzling, with more and more types and better quality, but the prices are getting cheaper and cheaper. Just like Lenovo competes with other large computer companies to launch the cheapest home PC, just like Geely competes with foreign sports car manufacturers to build China's first sports car. Here, we can also understand that competition has made great contributions to the improvement of people's living standards.

Article 3: Competition is survival.

The darkness of the whole world can't be a small candle that loses its luster!

There are often many people in the world who are reasonable and unexpected. Aren't Iraq and America good textbooks? The United States is a hegemonic country. America dominates the world. After the outbreak of the US-Iraq war, many people lost their families. Only a 3-year-old child snuggled up to her mother and looked at her kind face. Tears can't help falling. The lights in the hospital are dim and dark. At the age of 3, he lit the candle in his hand, knelt on the ground and looked at his dying mother. His son understands a lot, a lot.

Obviously, people are competing with each other, society is competing with each other, and countries are competing with each other. If they fall behind, they will be beaten. There are walls between people, dreams between children and old people, and wishes between old people and young people.

Nowadays, the society is terrible, competition is everywhere, challenges are still going on, failure is temporary, success will be my future, I believe my success tomorrow can not be separated from my efforts today, my failure yesterday will be my driving force for success, I can

Maybe you are a little wronged, maybe you are a little dissatisfied, but now you are eliminated. I really appreciate this sentence. Tomorrow's flowers bloom for me, today's fruits have withered, innovation is everywhere, and challenges continue.

I would like to be the boy you admire in fairy tales, and embrace success, the future and my own tomorrow with open hands.

Competition is survival, competition is motivation, competition is the direction of progress, and it is your own tomorrow. I can.

Where there is failure, there is success, where there is success, there is failure, and competition is survival!

Article 4: Desire to survive.

Spring is coming. My mother and I planted five kinds of seeds on the balcony: henna, boiled soup flower, morning glory, mung bean and pod. Under the careful care of my grandmother and I, they soon poked their little heads out one by one. However, before long, some of these lovely little Xin Wei died slowly.

I want to know why these little Xin Wei died. What happened to them? Later, my mother told me that our house is a closed balcony, and sunshine and ventilation can't meet their needs. From then on, I gave up hope for the remaining three pepper seedlings, two watercress and four boiled soup flowers. Only the diligent grandmother watered them several times from time to time.

Summer has come, and I am delighted to find that two beans have grown long seedlings, and only one boiled soup flower has spread its branches. Under its branches, there is a thin pepper seedling and three dying boiled soup flowers! Look how lush these two pots of aloe and chlorophytum are! Although the boiled soup flowers downstairs have already bloomed, although the hungry bean sprouts downstairs have already covered the wall. But I just hope they can add a touch of green to my balcony. One morning in autumn, I accidentally found a pepper with a crooked neck with a small pepper on it to survive. I am very excited. What surprised me even more was that the boiled soup bloomed one after another. Pods also produce clusters of white flowers. Yes! In order to survive, a small plant does not yield or bow in the face of difficulties, but what about us humans? I was lost in thought. ...

Chapter 5: Learn to survive.

Birds can only fly high if they master the skills of flying; Flowers can only compete with each other if they can stand loneliness; Trees can only thrive if they are tenacious. However, only by learning to survive can people open the door to success.

I remember one summer, I went to the supermarket with my parents. After shopping, my father paid the money, so I followed him, but when I reached the corner, my father was gone! After dinner, fear and panic came at me together. This familiar place suddenly became strange, and I was so scared that I almost cried! I ran around aimlessly, and my blood was boiling all over. In desperation, I used my quick wits to find a waiter and told my aunt about my "unlucky trip". My aunt held my cold little hand with a warm hand and gently smoothed my hair. My heart is like a frightened deer in shock. Aunt took me to the broadcast room and told me all the way to comfort me. When I arrived at the studio, my aunt asked me about my situation and shouted at the radio to let my parents lead me. My parents were so worried about me that they almost cried. When I heard this, they came to me like crazy. Seeing my parents, my depressed mood suddenly relaxed. What a thrilling experience for a 5-year-old child!

Life is full of ups and downs, but we can't lose the way of life, don't exhaust ourselves in survival, we must overcome fragility and learn to survive! In a word, we should learn to survive in life. In the face of danger, we should fight death with wisdom, courage, strength and belief, and care for the delicate flower of life!

Article 6: Survival of the fittest

Nature is like an arena, where all kinds of species fight to the death, and nature often gives these gladiators unbearable blows and pressures. Therefore, old species are constantly withdrawing from the historical stage, and new species are entering this life-and-death arena. What can survive in the end is to adapt to the harsh environment of nature and the rules of survival of the fittest.

In ancient times, dinosaurs once ruled the earth for more than 200 million years, which was inseparable from their living environment. They constantly temper themselves in the environment of the jungle to adapt themselves to this harsh environment and survive. The crisis of death surrounds them all the time, urging them to fight for their lives. So dinosaurs became more and more powerful and became the leading overlord on the earth. However, they did not adapt to the harsh natural environment and thus disappeared into the torrent of history.

Recently, it is the evolutionary history of human ancestor forest apes. In the rapid changes of nature, there are fewer and fewer areas suitable for apes to live, so most apes are forced to follow the historical trend, change their living habits, start walking upright in the fields, work with their hands, create tools, develop civilization, and finally evolve into today's human beings. Those "die-hards" who are unwilling to change their habits and adapt to the environment have only evolved into a group of apes, using only natural tools.

In the almost cruel screening of nature, all species that can successfully survive the test have amazing magical skills. Birds fly and fish swim, lions are fierce, tigers are fierce and wolves are fierce.

Today, although the wisdom of human beings can make them more capable in the face of various challenges from nature, such as diseases, famines and natural disasters, human beings have begun to face many severe tests, such as rapid population growth and declining population quality. Human beings have started a new round of "survival of the fittest" in these challenges that do not belong to nature.

Human beings began to pursue high quality and high grade life. Because no matter how many mediocre people are just mediocre people, no matter how few elite people are, we started a competition with the skills that distinguish human beings from others-wisdom and civilization. This kind of struggle is far from being comparable to wild animals, and it is a competition that can change the future of human beings and even nature. The significance of victory is far from the victory of primitive struggle in nature.

We advance wave after wave and run on this long and arduous runway, but we don't give up, shrink back or regret, because we have found the goal and meaning of survival. In this fun-filled competition, we understand a truth: this world has always been the survival of the fittest.

Article 7: Survival of the fittest

Candle is an insignificant little thing, and now it may never be seen at home again. Before the invention of electric light, candles were the brightest, so they were reused. But after the invention of electric light, even the poor can gradually use it, so it was naturally eliminated.

Dinosaurs existed before humans. They were one of the overlords at that time. All the larger land animals can't escape their killing. Only ants and cockroaches can survive. But with the passage of time and the change of environment, dinosaurs gradually became extinct, but in contrast, small creatures, such as fish, frogs and insects, and large animals, such as deer and horses, survived because they could adapt to various environments.

Dinosaurs could not adapt to various environments, so they were eliminated; Animals such as fish, frogs and insects can adapt to various environments, so they can survive. If they can continue to adapt to the future environment, then they will never be eliminated until they die of old age. Candles were eliminated because they couldn't keep up with the trend of the times, and lamps became the lights that people need now because they kept up with the pace of the times. People are the same. Only by adapting to the environment and keeping up with the trend of the times will we not be eliminated. Survival of the fittest is the truth.

Article 9: Survival of the fittest

Throughout the ages, the fittest survive and the unfit are eliminated. Everything in the world can stand on the world only if it adapts to the environment. In order to prevent the rubber bucket from being blown down by the wind, the little boy in the material specially filled the bucket with clear water, so that the bucket could still stand on the ground in the strong wind.

Adapting to the living environment is equally important for the development of our senior high school students. One of my senior sisters once told me about her experience: she was a top student in junior high school, but after entering high school, she could never adapt to high school life. She thought that her learning methods in junior high school would be equally effective in senior high school. Unexpectedly, after two exams, her academic performance plummeted. She readjusted her mentality, changed her learning methods reasonably according to her actual situation, and finally improved her grades. It is precisely because she mastered the law of learning competition and adjusted herself in all directions that she adapted to high school life and improved her strength. The rubber bucket in the material changed its situation before adapting to the strong wind, and it was invincible under the attack of the strong wind.

So are we. Isn't it the same for the survival and development of enterprises and even countries? Only by adapting to the needs of society, adjusting its industrial structure, changing its business plan, finding a new way out and adapting to the competition of enterprises can enterprises not be eliminated.

Cactus is not an innate ability to survive in the desert. The ancestors of cactus did not have thorns, but in order to adapt to the arid environment of desert and reduce water loss, its leaves gradually turned into thorns, which improved its viability, kept itself from being eliminated by the desert environment and added vitality to the desert. Cactus, like a rubber bucket in the material, adapts to the environment by changing its shape, so it has not been eliminated in the competition for survival.

There is competition everywhere in human society. If you don't want to be eliminated, you must wait and see, sum up the laws of social competition, and then adjust your situation according to your actual situation, not sticking to traditional methods, so as to adapt to the social environment.

Survival of the fittest, elimination of the unfit. Adapting to the environment is very important for everything in the world. Change yourself, adapt to the environment, learn to grow in the competition, enrich yourself and enhance your strength. Just like a rubber bucket in matter, we should strive to change our conditions to adapt to the environment so as not to be eliminated by society.

Article 10: Survival of the fittest

Darwin's phrase "natural selection, survival of the fittest" was originally an introduction to the survival law of natural creatures. Isn't it the same for humans? -inscription

Only the strong will be remembered forever; Maybe you will think my statement is too extreme, but that's the truth. At the 20 12 London Olympic Games, Ye, who was only 16 years old, broke the world twice and won two gold medals, which can be said to be an athlete's lifelong honor and suddenly became a hot topic in people's mouths. But who is the runner-up in the 400-meter medley? Who remembers? Maybe it's just 0. 1 second gap will change the fate of a lifetime, and the strong and the weak are this 0. 1 sec difference.

For high school students like us, the college entrance examination is our playground. After the college entrance examination every year, people always talk about "the top liberal arts students in the college entrance examination", "the top science students in the college entrance examination" and the ranking of some scores. However, people only remember the strong, these winners, and who will care about the students who failed in Sun Shan among the tens of millions of candidates in the country? The class that is about to take the college entrance examination always hangs "If you don't take the college entrance examination, can you compete for the rich second generation?" Such a slogan. In the national college entrance examination, senior three students feel that wasting a second for an exam is a waste of life. What is their purpose? For the college entrance examination? Rather, it is to become a strong man.

People always say that God is fair. Yes, it is fair, but the society we live in is not fair. None of us are ordinary people. Don't rush to deny my statement. When you look at other people's achievements, don't you envy them at all? It is out of the question. People who are willing to be ordinary are either hermits or fools. We don't want to change the innocence of childhood, but we are forced to grow up by this society. Life has its survival law, that is, "survival of the fittest". We can't change this environment, we can only change ourselves, let ourselves grow up and become a strong person. Maybe we need to work ten times and a hundred times harder than others on this road. Maybe we didn't succeed in the end, but we can't live like this. Everyone has ideals. We can't watch others laugh at the end every day, we can only applaud at the beginning. Maybe you have taken a step, but when your world blooms with victory, you will be grateful for this step. Don't give up the world ahead of time unless you try to be strong. When you are desperate, tell yourself "I'll try again" and maybe you can really stick to the finish line.
