Essay about World Expo

The 2010 World Expo will be held in Shanghai. Its proposition "Cities make life better" indicates that Shanghai and other cities will use and transform the natural environment to create a highly artificial living environment for the benefit of all. city ??dwellers.

The 21st century is a green century. The theme of the World Expo in Aichi, Japan is "The Wisdom of Nature." From this we can see that people are paying more and more attention to nature and ecology. The dominant residence in the 21st century is green home, the dominant food in the 21st century is green food, and the dominant environment in the 21st century is green environment. Green is also an eternal theme for mankind. Greening is an important part of embodying greenness.

Greening, this word is no stranger to us. As we all know, greening can beautify the environment, release oxygen, weaken noise, lower temperatures, block wind and sand, and improve the environment. Not only that, greening can also reduce human emotions of fear and anger and promote positive psychological reactions. It can be said that greening is an indispensable part of life.

Shanghai at the 2010 World Expo made greening the highlight of urban planning. As the countdown to the World Expo bid begins, the hands on the dial that are restless every second stir up the heartstrings of all those who care about the World Expo, especially the staff of the Shanghai Greening Administration who are closely related to the World Expo project. After all, 400 hectares 60-80% of the bid site will be green space. Greening is very important to the urban construction of the Shanghai 2010 World Expo and to improving people's quality of life, and it can also drive economic growth.

First of all, greening can promote Shanghai’s urban construction. It is understood that the 2010 World Expo will have multiple green plant corridors perpendicular to the Huangpu River, extending the green belt from the riverside area to the hinterland of the city, just like the link between modern cities and nature; against the backdrop of greenery, a The 400- to 500-meter-long Flower Bridge, dedicated to tourists for sightseeing, will span both sides of the Pujiang River and become a landmark building connecting the past, present and future. After the World Expo, the Expo space will be transformed according to the urban prototype of this area and integrated into the urban area of ??Shanghai. Green corridors and canals will be retained. The flower bridge crossing the Huangpu River will also be retained. It can lead strolling tourists to the new city park. After the exhibition, it will become part of Shanghai's cityscape and become another iconic landscape of Shanghai.

Secondly, greening can improve people's quality of life. On February 2, 2004, Shanghai was officially awarded the title of "National Garden City". Shanghai also proposed the goal of building a forest city. In 1990, Shanghai was still in the stage of paying off debt; but in 2004, Shanghai built 1,800 hectares of new green space, with a green coverage rate of 36%, and the per capita public green space in the urban area reached 10 square meters. The blind area within the 500-meter service radius of greening has been basically eliminated in the inner ring line, and a large number of large public green spaces have been built; due to the 2010 World Expo, more urban green spaces will be constructed. In the construction of green spaces, we not only highlight the ecological functions, but also pay more attention to the comprehensive service functions and urban landscape functions of green spaces. With this development momentum, it will be just around the corner for Shanghai to reach its goal by 2010.

Not only that, greening can also drive economic growth. Due to the 2010 World Expo, housing prices in Shanghai will increase. In terms of real estate investment, data shows that the most direct beneficiary of green spaces is real estate developers: Parks and green spaces invested and constructed by the government are always surrounded by "green spaces"---there are almost no housing prices near the parks that are "high as the grass grows." In recent years, property prices near parks have increased by at least 1,000 yuan per square meter, and the average number of units sold in properties close to green spaces is much higher than in properties far away from green spaces.

A home that lacks green means it lacks tranquility and serenity. There is no green grass, only patches of pale road, dazzlingly pale under the strong sunlight...

Water is the source of life, and green is the color of life. Only a city full of green can be full of vitality and vitality...

Green is the eternal concept of mankind

Green is a symbol of civilization.

Green, it shows the inspiration and charm of nature.

Let us take action now to make the city more green and more vibrant.

Afterviewing the Shanghai World Expo

Colorful light beams and colorful balls passing through Flag ships, graceful fountains, changing music and splendid fireworks...

On April 30, on the banks of the Huangpu River, a party was divided into "China Welcomes You", "Gathering at the Expo" and "The World Rejoices" The grand multimedia light fountain fireworks show in three parts brought the 159-year-old comprehensive World Expo to ancient and modern China for the first time.

At the beginning of the performance, a warm Chinese red and the slogan "China welcomes you" appeared on the big screen. Red fireworks flew into the night sky, and red beams of light shot across the river. The Huangpu River seemed to be paved with a giant banner. The red carpet welcomes guests and friends from all over the world.

Holding the World Expo has been a long-standing dream of the Chinese people. Liang Qichao and others once proposed hosting the World Expo in Shanghai, hoping that their motherland would "sleep like a sleeping lion and break its dreams, and a sick country will become seriously ill."

As times change, the relationship between China and the World Expo has become increasingly close. An open China welcomes the World Expo, which embodies the splendid civilization of mankind. On the night of the 30th, every beam of light and every cluster of fireworks released the Chinese people’s World Expo dream.

Blue and green gradually become the main colors of lighting. The bright, cheerful and enthusiastic rhythm makes people feel the harmony and beauty of urban life.

With the development of industrialization and urbanization, while cities allow people to enjoy a better life, they also bring difficulties and challenges such as traffic congestion, environmental pollution, and resource shortages. The Shanghai World Expo is the first World Expo with a city theme. During the Expo, people will exchange experiences on sustainable urban development.

The LED luminous balls floating from the Lupu Bridge change into red, yellow and orange colors and stretch down the river endlessly. More than 200 flag ships, towed by three speedboats, met the LED luminous balls flowing down the river on the river. Speedboats towed fireworks, and hundreds of flag ships passed through the colorful balls. This is a unique "water entrance ceremony".

The concept of "Romantic Water" comes from the classic Chinese love story "Butterfly Lovers". A group of permanent fountains along the Huangpu River reproduce this touching story. As the music changes, the dance of water turns into a screen of water, and a large projector projects colorful flowers and thousands of butterflies, reflecting the harmony between man and nature.

It has always been the ideal of the Expo family to advocate the establishment of a harmonious world in which peace is paramount, people-oriented, people respect and love each other, and people and nature are close to each other.

Golden fireworks were first lit from Lupu Bridge. Colorful fireworks shot up from barges on both sides of the strait and on the river, chasing each other and competing for beauty.

Silver and purple fireworks were the first to appear, and then all kinds of colorful and dazzling fireworks bloomed one after another. "Smiling face" and other shaped fireworks depict the picture of an open China. Golden fireworks were set off from both sides of the strait and met each other in the sky above the Pujiang River, forming a special "hand in hand" shape.

As the music of "Ode to Joy" played, fireworks bloomed. All searchlights, lasers, and fountains joined in the colorful display of light and fire, filling the sky with brilliance and illuminating the night sky.

Scientific development and sustainable development are the concepts pursued by the Shanghai World Expo. Liu Wenguo, assistant director of the World Expo Bureau and deputy director of the Shanghai Municipal Bureau of Culture and Radio, said that the fireworks used in the opening ceremony were very "low-carbon" - smoke There are few, the sound is light, and the colors are very bright.

In addition, the 2,000 guest seats for the opening ceremony were made of discarded milk cartons, program notes and handbags were made of recycled paper, and low-energy speakers and large LED screens were also used extensively. . More than 200 flag ships used at the opening ceremony will also be donated to disabled athletes for training.

"Chinese elements" are present throughout the performance. "The shapes of firecrackers, gongs and drums, Chinese red, Butterfly Butterfly, and the 'fish' symbolizing abundance every year make the whole performance achieve the integration of nationalization and internationalization." Liu Wenguo said.

David Atkins, chief director of the opening ceremony’s outdoor lighting and fireworks fountain installation performance, said: “Such a performance would have taken at least a year and a half to be held in any other country in the world. In China, it only takes half a year or even less. This reflects China’s strong resource allocation capabilities.

”

In the early 19th century, people began to use gas lamps (gas lamps), but gas was supplied by pipelines. Once the gas leaked or was blocked, it was very easy to cause trouble. People were very eager to reform lighting. In fact, Edison set an impossible task for himself: in addition to improving lighting, he also needed to create a power supply system.

So he and his partners in Mengluoyuan worked tirelessly for 1,600 years. After many experiments with heat-resistant materials and more than 600 kinds of plant fibers, he created the first carbon filament light bulb, which can burn for 45 hours at a time. Later, he continued to improve the manufacturing method on this basis, and finally introduced that it can burn for 1,200 hours. The bamboo filament light bulb.

In the mid-1880s, Edison's electric light business achieved success. This success brought him greater fame than any previous achievements. Before the mid-1880s, he was very successful. He rarely made mistakes. After the mid-term, although he also made great achievements, failures were also common. One of Edison's most unlaudable behaviors was his criticism of alternating current, saying that it had side effects and could cause death and injury, but he did not. Add specific explanations. So someone said, "It is very contradictory for a person like him who has made many inventions to attack other people's new inventions. "He opposed the use of alternating current in favor of direct current, and thus lost a fierce and stubborn debate. In this regard, it reflects the shortcomings of stubbornness and conservatism that gradually developed after Edison became a celebrity.

At the 1876 World Expo in Philadelphia, Bell, the inventor of the telephone, was experimenting with the world's first telephone.

In 1888, that year. When Eastman named his film product, he wanted to use the letter "K". Eastman believed that the word "K" could give people a strong and powerful feeling. It happened that the sound of a camera shutter "clicking" next to him gave Eastman inspiration. . So the name "KODAK" with the letter "K" at the beginning and end was born. Eastman chose yellow as the color of product packaging. He believed that yellow reflected strength and brightness.

In 1889, Eastman will. Sensitive film coated with photosensitive emulsion on long strips of celluloid not only facilitates the shooting of long-term moving images, but also makes it possible to project these images.

In 1889, Edison saw French photographers while visiting the Paris World's Fair. A device for continuously displaying photos invented by Marley, and a new type of photosensitive film invented by Eastman at that time. He used the phenomenon of persistence of human vision to invent the movie camera at the 1893 World's Fair in Chicago. , Miss Kodak wearing yellow advertising clothing has become the most beautiful scenery of the World Expo. Kodak products have become synonymous with photographic supplies. The Kodak advertising slogan designed by Eastman is "You press the shutter 'Kada' and everything will be left." Kodak'" is even more well-known and widely circulated. Kodak became the world's film giant in one fell swoop. Edison once said: "At the World's Fair in Chicago in 1893 (these films released by the kinetoscope), they attracted a large number of audiences. We didn't notice it at first, but later we found out that two British people who were interested in this exhibition learned that I had neglected to apply for patents overseas, so they took the opportunity to build an independent factory and mass-produce it. ”

In 1914, the American Eastman Kodak Company invented the color photographic plate-making method. In 1923, Kodak color film was born.

“You press the shutter ‘Kada’, and everything will remain.” "To 'Kodak'". Kodak's advertising slogans and products at the World Expo for more than 100 years are still in the world today: brilliant and brilliant.
