With the development of global science and technology, our life is getting richer and richer. Subway, high-speed rail, plane, telephone, mobile phone, escalator, etc. The development of these technologies has changed our lives. The maglev train does not run close to the rail, but runs on the rail surface in the form of suspension. It turns out that it uses the attraction and repulsion principle of electromagnetic induction to float the train body, and then uses solar energy, wind power or hydraulic power to push the train forward. This kind of train will not be noisy, safe and stable, and will not pollute the ecological environment. The maglev train in Japan levitates the car body by using the magnetic field generated by electromagnets and coils. The maglev train in Birmingham, England levitates the train by using the magnetic field between electromagnetism and track.

Cement mixers transport mud, and loose mud blocks are used in the construction site. In order to prevent the mud from forming lumps, I rolled while walking. There is a large sports transport vehicle which is also a round box. It is used to transport liquids. The circular design of liquid tanker has some truth. First of all, the volume surrounded by a circle is made of the same material; Then it is round, without edges and corners, and it is not easy to be damaged. The pressure of the circular tank is also relatively uniform.

Satellites are high-tech communication buildings. Every few years, a satellite must be launched to the whole world. Satellite consists of stars, transponders, receiving and transmitting antennas, solar power generation system, attitude control and orbit control system. We see that TV programs thousands of miles away are receiving wars from satellite antennas to various regions, and some assistance will be provided separately. In this way, we can watch TV programs thousands of miles away.

High-rise buildings are very common in cities, so they have to be used because of the high land price. There are many forms of high-rise buildings, such as square column, circle and prism. Common zigzag buildings, like rectangular building blocks, have poor wind resistance. Cylindrical buildings have good wind resistance. Peach Tree Central Plaza Hotel in Atlanta, USA, is a conical hotel in the world, with a cylindrical building. Conical buildings have strong wind and earthquake resistance.

Technology is changing our lives, and it is leading us into a brand-new society. As long as we love science, study science and observe science, we can create a perfect realm!

The bell is about to ring at the end of the 20th century, and mankind is about to enter the ever-changing and unpredictable corridor of 2 1 century. How to face this complicated and fast-developing new century? How should we humans control our future destiny? I believe this should attract the attention of our Expo Organizing Committee and highlight this content at the Expo. Therefore, my theme for the 20 10 Shanghai World Expo is "Science, technology and humanities are better than Qi Fei".

Since the birth of mankind, it has possessed two weapons: science and technology and humanities. From the earliest drilling fire and carving stone to the present computer technology and the increasingly developed humanities and human culture, mankind has benefited from it continuously. With the powerful help of these two weapons, it has come to the information age from eating animals and drinking blood. The function of the two is self-evident, and the relationship between them is like two ends of a balance, which cannot be neglected or neglected. Especially for today's situation, the comparison between science and technology and humanities is more important than that in Qi Fei.

This is the inevitable need of accelerating development in today's era. Nowadays, science has developed to a considerable height. Computer network and information technology, human genome engineering, protection and utilization of resources, conquest of various terminal diseases, etc. All these developments are the embodiment of the rapid development of science and technology today and give hope and motivation for human survival. At the same time, the development of science and technology has brought great impact on values and ethics. Whether cloning technology can be applied to human beings and whether gene technology will be abused to bring disaster have brought a lot of anxiety and fear to human beings. At this time, human beings urgently need the independence of humanities, solve all kinds of puzzles on the road of human development, and clear away ideological and moral obstacles, just as Marxism has brought new hope to China. The two are equally important, and their complementary relationship can be seen.

This is an inevitable need to improve the quality of all mankind. The universe is a combination of individuals and people. For the peace and development of the world, the role of the individual can not be ignored, and the quality of the individual needs to be improved urgently, thus promoting the improvement of the quality of all mankind. This task is especially severe for those developing countries. Therefore, it is necessary to strengthen the construction of "two civilizations" for individuals, arm people with modern science and technology, humanities, scientific and cultural knowledge and correct world outlook, and make them perfect. As long as people are perfect, the world is perfect. This wishful thinking and beautiful ideal should also be our goal.

In order to cooperate with the establishment and embodiment of the above-mentioned theme, Expo 2014 can focus on the construction of the theme pavilion "Science and technology and humanities-wings of human beings", and use high-tech sound, light and electricity technologies to review the history of human development and look forward to the future of the earth with the clue of the development and relationship between science and technology and humanities, so as to attract and educate visitors. Countries can also set up their own exhibition areas to introduce their own science and technology and humanities, so as to open a window for countries to understand each other. I believe that through such efforts, the concept of "science and technology are better than Qi Fei" will be deeply rooted in people's hearts.

The development of human society is undoubtedly the history of scientific and technological development, and the development of modern civilized society is closely related to the rapid development of science and technology. The development of science and technology has brought convenience and quickness to our daily necessities, communication and consultation! There used to be such a picture, which was divided into three small pictures, and the background of each picture was summer evening. The first picture depicts an old woman lying in bed, squinting wearily, holding a bamboo leaf fan in her hand, driving away mosquitoes and shedding huge tears; The second picture shows an older gentleman sitting in a wooden chair with a worn-out book in his hand, but the most difference from the first picture is that his summer tool is not a fan, but an electric fan with a metal shell on his desk, and the wind blows his slightly wet hair. However, he doesn't seem to be bothered by mosquitoes, but enjoys reading; As for the third picture, it is completely different from the first two pictures. The figure in the picture is a child, playing with building blocks, without any worries, with a happy smile on his mouth. Of course, this is the convenience brought by air conditioning!

From "bamboo leaf fan" to "metal shell electric fan" and now every household has "air conditioning" This is the credit of science and technology! Of course, technology has brought us more than that, and there are two most important things, namely communication and consultation.

In ancient times, people transmitted information through post stations, flying pigeons, beacon alarms, symbols, language, eyes and touch. Today, with the rapid development of science, communication is basically done by wire or radio, and various communication methods such as fixed telephone, wireless telephone, mobile phone, Internet and even videophone have appeared one after another. We have to say that communication technology has narrowed the distance between people, improved the efficiency of communication and profoundly changed the way of human communication. With communication technology, life is even more "sesame blossoms are on the rise". People call when they have something to do, and call when they have nothing to do. But the most powerful example is people who need urgent help. If there is a fire at home, you can call119 immediately; If there is an accident on the road, you can call110; If you want to know some local fixed telephones, you can consult114; I think this is the convenience brought by technology! The convenience of consultation makes people shout "magic"! "awesome"! "convenient"! ! Take information consultation as an example. Information consultation is a business activity based on the collection, processing, transmission, effective utilization and feedback of all kinds of information. Information consulting industry is a knowledge-based industry that uses various information processing technologies to collect, process, sort out, analyze and transmit all kinds of information and provide customers with information products such as solutions, strategies, suggestions, plans or measures to solve problems. With consultation, people can know what is happening in the world at home. Is it inconvenient?

People can't live without technology, just as technology changes life!
