Nature-loving speech

The speech pays special attention to clear structure and concise level. In study, work and life, there are more and more things that need to be spoken. How to write a speech to avoid stepping on thunder? The following is my speech about loving nature, which is for reference only and I hope it will help you.

Speech on loving nature 1 Japanese scientists are inspired by ants foraging. They developed a large-scale integrated circuit to simulate the foraging ants Qixin carrying food together and sending information from the nearest "food source" to the "ant nest" in sequence. According to this new information processing method, it is possible for people to develop a new computing mode computer.

There are still many inspirations that human beings get from nature. For example, an arch bridge was built to imitate the characteristics of egg shape; Inspired by the flight of birds, people invented airplanes. I cut off my fingers from the thatch and invented the saw ... There are many animals and plants in nature, which hint at the mysteries of nature in their own unique way of life.

There are many inspirations from nature. There is a kind of snake called rattlesnake. It has an infrared eye. Through the eyes of this snake, human beings have developed a missile with eyes like rattlesnakes. Its name is rattlesnake missile, so it is named rattlesnake missile, because humans are made according to the eyes of rattlesnakes.

Rattlesnake missiles can accurately track the enemy with "hot eyes" like rattlesnakes until they are destroyed. Because the "hot eye" of the rattlesnake will judge the enemy's position according to the enemy's temperature, aircraft, warships, tanks and other things, the rattlesnake missile can accurately hit. Mobile low-altitude short-range all-weather ground-to-air missile developed by France. It is mainly used to deal with low-altitude and ultra-low-altitude fighters and armed helicopters to defend airports and ports, and can also be used to deal with cruise missiles. Missile length 2. 94 meters, bullet diameter 0. 156m, weight 84. 5 kg, transmitter length 3. 02 meters. The warhead adopts fragment focusing type, with a total weight of 13. 9 kg, killing radius of 6 ~ 8 meters. The power plant is a single-stage solid rocket engine, and the guidance mode is full-range radio command guidance, with an operational radius of 500-8500m and an operational altitude of 50-3000m. The missile has semi-off-road maneuverability.

Colorful butterflies, such as those with double moon patterns, those with brown veins, especially those with fluorescent wings, have golden wings, green wings and blue wings in the sun. Scientists have brought great benefits to military defense by studying the color of butterflies. During World War II, the Germans surrounded Leningrad in an attempt to destroy its military targets and other defense facilities with bombers. Schwarzenegger, an entomologist in the Soviet Union, put forward the principle that the color of butterflies is not easy to be found in flowers, and covered military facilities with butterfly-like camouflage. Therefore, although the Germans went all out, the military base in Leningrad remained undisturbed, which laid a solid foundation for winning the final victory. According to the same principle, people later produced camouflage uniforms, which greatly reduced the casualties in the battle.

Beehives are composed of small hexagonal beehives, and the bottom of each beehive is composed of three identical diamonds, which are exactly the same as those calculated by modern mathematicians-rhombic obtuse angle 109. 28', acute angle 70. 32' is exactly the same, it is the most material-saving structure, and it has a large capacity and is extremely strong, which makes many experts admire it. People imitate its structure and make honeycomb sandwich structural plates with various materials. This structural plate has high strength, light weight and is not easy to conduct sound and heat. They are ideal materials for making space shuttles, spaceships and artificial satellites. Polarizers sensitive to the direction of polarized light are arranged adjacent to each eye of the compound eye of bees, which can be accurately positioned by the sun. Based on this principle, scientists have successfully developed a polarized light navigator, which has been widely used in navigation.

Dragonflies can generate local unstable airflow different from the surrounding atmosphere through the vibration of their wings, while Wells uses the vortex generated by the airflow to lift himself up. Dragonflies can soar under a small thrust, not only forward, but also backward and left and right, and its forward flight speed can reach 72 km/h. In addition, the flight behavior of dragonflies is simple, with only two pairs of wings flapping constantly. Scientists have successfully developed a helicopter based on this structural foundation. When an airplane flies at high speed, it often causes violent vibration, and sometimes even breaks its wings, causing the airplane to crash. Dragonflies rely on aggravated wing moles to fly safely at high speed, so people follow the example of dragonflies and add weights to the two wings of the plane to solve the thorny problem of vibration caused by high-speed flight.

Fleas have a high jumping ability, and aviation experts have done a lot of research on it. Inspired by its vertical take-off, a British aircraft manufacturing company successfully manufactured a Harrier aircraft that can take off and land almost vertically. According to the structural characteristics of insects' single compound eyes, modern television technology has created a large-screen color TV, which can also be composed of small color TV screens. Some specific small pictures can be framed at any position on the same screen, and the same picture can be played as well as different pictures. According to the structural characteristics of insect compound eyes, scientists have successfully developed a multi-aperture optical system device that is easier to find targets, and it has been applied in some important weapon systems abroad. According to the mutual inhibition principle of some aquatic insects compound eyes, an electronic model of lateral inhibition is made, which can be used in various photographic systems. The photos taken can enhance the edge contrast of the image and highlight the outline of the image, and can also be used to improve the display sensitivity of radar, and can also be used for the preprocessing of text and picture recognition systems. Based on the processing information of insect compound eye and the principle of directional navigation, the United States has developed an engineering model of terminal guidance seeker with great practical value. Japan has developed new construction methods of construction machinery and buildings such as hexapod robots by using the morphology and characteristics of insects.

They fall like paratroopers, catkins and poplars, and they are as white as salt scattered in the air.

The snow on the ground is more than a foot deep. Walking on the snow makes a creaking sound, which is very nice. We left a long trail of crooked footprints behind us.

I walked on my way to school and let the snow fall on my body, face and neck. I don't want to speed up my pace, just want to enjoy the comfort brought by this beautiful snow.

I can't help but smell a smell. It's the smell of snow, a sweet taste, and a bitter taste mixed with sweetness. This may be Yun Yun's sister's tears. I wonder why she is crying. Someone must have bullied her! That's why it snowed. She used it to tell her grievances. The snow is so heavy. ...

It takes a lot of effort to trudge in the snow, but I am in no hurry to walk to school, because this spirit of nature deeply attracts me. I enjoy every moment with her. As long as I am with her, happiness and happiness will always accompany me, and sadness and pain will stay away from me. I really hope that this road can go on forever, without end, and accompany me forever!

Snow, the spirit of nature, gives me happiness and spends every winter with me! Although winter is very cold and accompanied by snow, I am never lonely …

Dear teachers and students:

Hello everyone!

Today, the content of my speech is "it is everyone's responsibility to protect the environment"

Students, we used to have a beautiful and rich home. At that time, lush vegetation, tree-lined, flowers in full bloom, birds contending, streams flowing slowly, singing sweet songs, the air was very fresh and gave people a refreshing aesthetic feeling. Mother Earth has also brought us happiness!

But, you know what? In a beautiful environment, disasters also come unconsciously. Now, due to the lack of human appreciation of the environment, wantonly cutting down trees and building factories, various environmental problems follow one after another: forest degradation, sandstorms, soil erosion, floods, frequent fires, harsh noise, stench, acid rain and red tide, and piles of waste residue ... According to current statistics, the ozone hole in Antarctica is gradually increasing, the ultraviolet radiation on the ground is enhanced, and the invention rate of skin cancer is increasing; 65.438+0.2 billion people live in turbid air; 65.438+0.2 billion people are short of water; 12% of mammals and 1 1% of birds are endangered; Loss of 20 billion tons of topsoil every year; The forest grows at the rate of 450 hectares per year.

These repeated disasters are not enough to warn us that it is urgent to protect the environment? So, please protect the environment for our planet and ourselves! The earth is our home. Since we live and work in peace and contentment on the earth, we should protect the environment and maintain the ecological balance. Protecting the environment is everyone's responsibility. Let's start with the little things around us!

My speech is over, thank you!

Judges, leaders, uncles and aunts, colleagues,

Good morning!

Welcome to the live broadcast of Xiao Liao's Talk about Health, which is a special program about the road to natural health. I'm Liao, the speaker.

Before the program begins, I'd like to invite all the people present to join me in celebrating the victory of the 29th Beijing Olympic Games with our warmest applause. China ranks first in the world with 565,438+0 gold medals, standing at the peak of history! Looking back at history, we can easily find that whether it is a country or a nation, or the whole mankind, social progress and civilization development are always synchronized with the improvement of human health. It can be said that all the progress of civilization is to improve the quality of human life, and the highest pursuit and core essence of quality of life is health! In ancient times, people learned to use fire to get health and warmth; At the forefront of science and technology, the human genome project is making unremitting efforts for the secret of health; In ancient Greece, philosophers issued the voice that "life lies in movement"; In China, Huangdi Neijing put forward the principle that "all diseases are prevented by merits".

Health is always the most important part of all human dreams. Health may not be everything, but without health, everything in life, wealth, honor, status, family and money, is meaningless; Even without healthy people, there is no capital to pursue these things. There used to be a psychological survey that made people choose to give up in all the pursuits of life, and all people did not choose to give up health. I want to ask everyone here, do you want to be healthy?

For those who want to get healthy, I send you four poems: youth cannot last forever, honor and disgrace are like smoke, money is outside, and health is precious wealth! Many people tell me that I know the importance of health, but what can I do to be healthy? Actually, I have given you the answer. Health is by no means a complicated matter. There are many secrets to help our health, but the most mysterious truth is only one, and that is the way of nature.

The human body is the most precise and perfect creation in the world, and it is an extremely harmonious and balanced existence. We only need to conform to the universe and our own natural laws and use the body correctly according to the human body instructions written in heaven and earth, which is in line with the true meaning of health. We can live a healthy life for 100 years according to the service life set by nature for our bodies. Here, I would like to invite everyone here who wants to live a long and healthy life to join me in shouting our declaration of health and longevity: I want to live to 120!

I like all kinds of sounds of nature, but in the noisy city, I can only hear the sound of cars whizzing by and the noise of construction machinery. It is such a brake ear that people can't think of words like "beautiful and elegant".

My favorite bird song is almost unheard of, but fortunately, there are only a few sparrows that can bring me a little spiritual comfort. Cheerful cries with a little melancholy, lovely figure dancing on the branches, spreading its wings in the air, like a movie, attracted me to savor. However, all this came to an abrupt end. With the roar of joy brought by injury and plunder, several gray feathers fell lightly and it struggled. It struggled in the boy's hand. The cry of sadness stung me. I can't stand such a blow. Why even the last life given by nature was ruthlessly taken away?

I yearn for the sound of leaves colliding, just like the moonlight music played by the pianist, but it seems to be slowly swallowed up by the noise of the city. It is naive and unfair in the world, leaving us only accompaniment, which can only be heard sporadically on campus. I accidentally heard that an old man was looking after a large camphor tree forest and wanted to see it. However, within a few days, the news channel broadcast the unfortunate news that the forest was destroyed. Looking at the sawed-off trees on TV, I felt a pain in my heart and ruined a group of lives.

Every time I appreciate the sound, the beautiful sound comes to an abrupt end in the destruction of people. Where should I find the sound of nature that I hope?

God is really unfair. The song of the bird I love is so sad. The rustling of my favorite leaves was swallowed up by the roar of the chainsaw.

I like the sound of nature. I hope that ignorant people will wake up early and listen to the sounds of nature!

Speech on Love for Nature 6 In the strange and unpredictable nature, all kinds of sounds are intertwined to form a wonderful natural symphony. In this magnificent symphony, there is a sound that I like best. Sometimes it's like a melodious flute, sometimes it's like a stormy sea. This is rain.

When I was a child, I didn't like rain because it brought me tears. Rain seems to have affected people's mood. Whenever it rains, dreary weather, cloudy sky and muddy land make people particularly annoyed. Whenever it rains, I sleep at home to avoid the nasty weather. Now that I think about it, it's really interesting.

When I grew up, I fell in love with the rain. The sound of rain is always a kind of aesthetic feeling in hearing, whether it is neglecting to hit the phoenix tree or the lotus leaf in the shower, the rhythm is crisp and audible. But what I like best is the rain in summer.

At first, it didn't rain much, tinkling, like countless pearls falling on the tracts. In particular, the ancient music of knocking on roof tiles seems to be soft and sonorous, as far as near. Heavy and light, thick and thin, dribs and drabs, just like the ponder in Yu Boya's "Mountain Flowing Water". Gentle as rain, it seems to be telling a gentle voice.

The rain grew louder and louder, hitting the plane leaves. The water flowing from the eaves is noisy and crisp, which is really "like pouring large and small pearls into a plate of jade", which makes people feel relaxed and happy. Occasionally, there is a gust of wind, the branches twist, the leaves whir, and thousands of water drops are squeezed out, flying down and dripping under the eaves, creating a symphony of nature.

It's raining, the rain is getting smaller and smaller, and it's gradually restored to its original appearance. The hero's agitation seems to be gone forever, and it's raining again.

Looking at this unpredictable rain, I can't help thinking a lot.
