阅读理解 Car-free neighborhoods exist all over Europe．A quarter of households in Britain live without cars．Vauban in Germany is one of the largest car-free neighborhoods in Europe．If you live in the district, you are required to confirm once a year that you do not own a car-or, if you do own one, you must buy a space in a multi-storey car park on the edge of the district． Vehicles in most of the European car-free areas are physically stopped from entering the streets where people live．Exceptions are made for emergency vehicles and removal vans but not for normal deliveries．A few parking spaces nearby are available to buy(usually around one space for every five homes)and a few are reserved for car club vehicles．Cycling is a vital means of transport． Car-free areas of this kind exist in Amsterdam, Vienna, Hamburg and so on．There is even a small one in Edinburgh． There is another form of car-free development．Recently we have overlooked its potential．Most pedestrianzed(步行)city or neighborhood centers in Britain are almost entirely commercial．But a few farsighted councils have brought back housing and residents, without cars or parking, into city centers that would otherwise be deserted after 6 pm． Car-free UK was set up to improve European-style car-free development in this country．We are not anti-car, but pro-choice．We have recently run public meetings in London to set up a new car-free association for London, which is beginning to look at areas of the city from which traffic could be removed．We know considerable potential demand exists for traffic-free housing in London, and probably in a number of other major cities． |
