Background: By the time of 185 1 London World Expo, the British industrial revolution had been completed. With the emergence of large-scale machine production, human beings have entered "age of steam" and Britain has become "the factory of the world". The capitalist mode of production finally defeated the feudal mode of production in Britain. 1889 At the Paris Expo, the second industrial revolution was going on, and mankind entered the "electrical age". Materially, mankind has entered the age of steel. The development of science and technology has brought a high development of productive forces and a more progressive social civilization to the capitalist world.

Change: The first industrial revolution created a world pattern in which the West was advanced and the East was backward. Britain has become the world's largest industrial power, and its overseas colonial expansion activities have been further strengthened, making it a country that exploits many countries and nations all over the world. The second industrial revolution concentrated most of the important industrial sectors in major capitalist countries in the hands of monopoly organizations, and capitalism entered the monopoly stage, which is the mature development period of capitalism. Capitalism has unified the world and made the economic ties between the East and the West closer, but the gap has also widened.

Influence: After the completion of the first industrial revolution, the foreign powers launched two opium wars, and China began to become a semi-colonial and semi-feudal society. Advanced China people began to learn western science and technology, and the Westernization Movement gave birth to modern industry in China. During the Second Industrial Revolution, foreign powers stepped up their aggression against China, and imperialism set off a frenzy to carve up China, which deepened the national crisis in China. China people's national salvation movement is on the rise, including the Reform Movement of 1898, the Boxer Rebellion and the Revolution of 1911.

Understanding: The purpose of hosting the World Expo is to celebrate major historical events or major commemorative activities in a country or region and to show human achievements in politics, economy, culture, science and technology. Hosting the World Expo will not only bring development opportunities to participating countries, expand international exchanges and cooperation and promote economic development, but also create enormous economic and social benefits for the host country and promote social prosperity and progress.
