There are now over 700 million motor vehicles in the world and the number is rising by more than 40 million each year. The average distance driven by car users is growing too--from 8 km a day per person in Western Europe in 1965 to 26 km a day in 1995. This dependence on motor vehicles has given rise to major problems, including environmental pollution, depletion of oil resources, traffic congestion and safety.
While emissions from new ears are far less harmful than they used to be, city streets and motorways are becoming more crowed than ever, often with older trucks, buses and taxis, which emit excessive levels of smoke and fumes. This concentration of vehicles makes air quality in urban areas unpleasant and sometimes dangerous to breathe.
In Europe most cities are still designed for the old modes of transport. Adaptation to the motor car has involved adding ring roads, one-way systems and parking lots. In the United Sates. more land is assigned to car use than to housing. Urban sprawl means that life without a car is next to impossible. Mass use of motor vehicles has also killed or injured millions of people. Other social effects have been blamed on the car such as alienation and aggressive human behavior.
A 1993 study by the European Federation for Transport and Environment found that car transport is seven times as costly as rail travel in terms of the external social costs it entails such as congestion, accidents, pollution, loss of cropland and natural habitats, depletion of oil resources and so on. Yet cars easily surpass trains or buses as a flexible and convenient mode of personal transport. It is unrealistic to expect people to give up private cars in favor of mass transition
Technical solutions can reduce the pollution problem and increase the fuel efficiency of engines. But fuel consumption and exhaust emissions depend on which cars are preferred by customers and how they are driven. Many people buy larger cars than they need for daily purposes or waste fuel by driving aggressively. Besides, global car use is increasing at a faster rate than the improvement in emission and fuel efficiency which technology is now making possible.
One solution that has been put forward is the long-term solution of designing cities and neighborhoods so that car journeys are not necessary all essential services being located within walking distance or easily accessible by public transport. Not only would this save energy and cut carbon dioxide emissions, it would also enhance the quality of community life, putting the emphasis on people instead of cars. Good local government is already bringing this about in some places. But few democratic communities are blessed with the vision--and the capital--to make such profound changes in modern lifestyles. A more likely scenario seems to be a combination of mass transit systems for travel into and around cities, with small low emission cars for urban use and larger hybrid or lean burn cars for use elsewhere. [br] According to the writer, a more ______ solution to the car problems is to combine mass transportation system with cars of low emission and low fuel consumption.
选项
答案
likely/practical
解析
由文章最后一句“A more likely scenario seems to be a combination of mass transit systems for travel into and around cities,with small low emission cars for urban use and larger hybrid or lean burn cars for use elsewhere.”可见,这样的方法和前面提到的“通过技术解决问题”和“重新规划城市的长远方法”相比是更为适当、更为可能、更为实际的。因此,我们可以回答为“likely”、“practical”或者其他含义相近的词。
