　　托福阅读城市化话题背景知识阅读：

　　Urbanization occurs as individual, commercial, social and governmental efforts reduce time and expense in commuting and transportation and improve opportunities for jobs, education, housing, and transportation. Living in cities permits the advantages of the opportunities of proximity, diversity, and marketplace competition. However, the advantages of urbanization are weighed against alienation issues, stress, increased daily life costs, and negative social aspects that result from mass marginalization.

　　Cities are known to be places where money, services, wealth and opportunities are centralized. Many rural inhabitants come to the city for reasons of seeking fortunes and social mobility. Businesses, which provide jobs and exchange capital are more concentrated in urban areas. Whether the source is trade or tourism, it is also through the ports or banking systems that foreign money flows into a country, commonly located in cities.

　　Economic opportunities are just one reason people move into cities, though they do not go to fully explain why urbanization rates have exploded only recently in places like China and India. Rural flight is a contributing factor to urbanization. In rural areas, often on small family farms or collective farms in villages, it has traditionally been difficult to access manufactured goods, though overall quality of life is very subjective, and may certainly surpass that of the city. Farm living has always been susceptible to unpredictable environmental conditions, and in times of drought, flood or pestilence, survival may become extremely problematic.

　　Cities offer a larger variety of services, such as specialist services that aren't found in rural areas. Supporting the provision of these services requires workers, resulting in more numerous and varied job opportunities. Elderly individuals may be forced to move to cities where there are doctors and hospitals that can cater for their health needs. Varied and high quality educational opportunities are another factor in urban migration, as well as the opportunity to join, develop, and seek out social communities.

　　Urbanization can be planned urbanization or organic. Planned urbanization, i.e.: planned community or the garden city movement, is based on an advance plan, which can be prepared for military, aesthetic, economic or urban design reasons. Examples can be seen in many ancient cities; although with exploration came the collision of nations, which meant that many invaded cities took on the desired planned characteristics of their occupiers. Many ancient organic cities experienced redevelopment for military and economic purposes, new roads carved through the cities, and new parcels of land were cordoned off serving various planned purposes giving cities distinctive geometric designs. UN agencies prefer to see urban infrastructure installed before urbanization occurs. Landscape planners are responsible for landscape infrastructure (public parks, sustainable urban drainage systems, greenways etc.)which can be planned before urbanization takes place, or afterward to revitalize an area and create greater livability within a region. Concepts of control of the urban expansion are considered in the American Institute of Planners.
