Section One The city is an accumulation of human civilization. Just as the American social philosopher Lewis Mumford put it, it is a special system which, fine and compact, has been designed to preserve the fruits of human civilization. Many Western languages have developed their versions of the term “civilization” from the same Latin word “civitas”(meaning “city” ), and it is by no means a coincidence. The city has played a significant role in the perfection of order in human society. Section Two The emblem(会徽), showing the image of three people ― you, me, him/her holding hands together, symbolizes the big family of mankind. Inspired by the shape of the Chinese character “世” (meaning the world), the design conveys the organizers' wish to host an Expo which is of global scale and which shows the various urban cultures of the world. Section Three Created from the inspiration of Chinese character “人”, the design roots deeply in Chinese culture. It tells the world the eternal core (永恒的核心) and theme of Shanghai World Expo will be always human. The mascot “Haibao” will become the messenger for the theme of World Expo 2010 Shanghai China “Better City, Better Life”. The basic structure of the Chinese character “人” in which each stroke supports each other also shows the concept that the beautiful life should depends on mutual-help(互相帮助). If the human are willing to support one another, the harmony among human, nature, and society will be available. Such an urban life will be nice. Haibao’s confident smile is expressing his sincere greeting from China ― “World Expo 2010 Shanghai China welcomes you!” 小题1:The underlined word “it” in Section One refers to ______.
