1、Unit 1 The Evolution of Transport交通工具的演化The evolution of transport has been closely linked to the development of humankind throughout the earths historyTransports early function was to meet the basic need of hauling food supplies and building materialsBut with the formation of tribes，then peoples，an

2、d finally nations，the societal and economic functions of transport became more and more complex. At first there was mobility required for individuals，clans，households，and animals to protect them against，and to escape from，the dangers of natural disasters and tribal aggressions，and in the search for

3、the best places to settleAs tribal groups formed and gradually established their geographical identity，transport was increasingly needed to open up regions for development，to provide access to natural resources，to promote intercommunal trade，and to mobilize territorial defenseWhen the first nations

9、s efficiencyFor centuries，and particularly during the takeoff stages of local economics，society required reliable，fast，and low cost transportThe search for appropriate technologies was relatively unconstrainedThere were times in human history when the demand for reliable and fast transport was espec

During such periods of local and international conflict, human ingenuity devised new transport technologies which often proved to be the decisive element for survival, and sometimes victory. Subsequently refined and develo

11、ped, such new technologies made it possible to better meet increasing transport demand, thus improving both economic progress and human welfare.顯然符合運輸?shù)氖滓獪蕜t是效率。幾百年來，特別是在本地經(jīng)濟的起飛階段期間，社會需要快速、 可靠、 和低成本的運輸。尋找合適的技術(shù)是相對無約束。倍時，在人類歷史上尤為突出的可靠、 快速的運輸需求，并快速解決方案所需的國家自衛(wèi)。在這樣的地方和國際沖突的時期人類智慧制定新運輸技術(shù)往往證明的生存空間，有時勝利的決定性因素

This resulted in bigger and faster ships and more reliable and sturdy land vehicles. Eventually, self-propulsion was introduced, exemplified by steamboats, the rail

13、ways, and then the automobile. Research and development in the transport field finally became an organized undertaking with specific goals and objectives. As the result of the consequent concentration of talent and expertise, more and more sophisticated transport technologies evolved, such as the ai

15、which include air, surface, and water transport. Special industry needs have led to the development of transport modes that have rather limited applications, such as pipelines, cables, and belts. Within current societal needs and preferences, as well as the economic requirements of cost effectivenes

17、 needs improved continuously, it became evident that such effectiveness had its price. A number of transport technologies implied high energy consumption and required substantial capital inputs in production and operation. As a result, several transport modes became expensive to the user. This cause

Many governments chose to subsidize transport, but quickly realized that the budget implications often caused serious distortions in their natio

Most existing transport modes are cri

With unabated growth of demand for transport and a progressively limited supply of energy, the costs of providing transport have increased steadily. In particular, the disproportion of petroleum requirements and petroleum supply has

Especially hard hit are countries with a partial or total dependence on an external petroleum supply, which have experienced growing deficits in their current accounts.最后，特別是石油、 世界能源資源日益減少，所引起的問題越來越多地阻礙了交通服務和操作。大多數(shù)現(xiàn)有交通工具都依賴石油衍生品的正常運作。對

25、Energy-supply constraints, high capital and operating costs, often with excessive foreign-exchange components, and the seriousness of transport-related environmental pollution account in large part for this problem. But transport is and will continue to be an essential requirement for world developm
