(A)

During the last ten years, our cities were full of cars, buses and trucks.Now the streets are completely crowded and it is very difficult to drive a car along them.Drivers must stop at hundreds of traffic lights.

What are our cities going to be like in ten or twenty years? Will many motorways(高速公路) be built across them? With big motorways cutting across them, full of noisy, dirty cars and trucks, our cities are going to be awful places.How can we solve the problem?

There are some good ideas to reduce the use of private cars.In 1971, for example, the authorities(官方) in Rome began an interesting experiment: passengers on the city buses did not have to pay for their tickets.

In Stockholm(斯德哥尔摩) there was another experiment: people paid very little for a season ticket to travel on any bus, trolley bus, train or tram all over the city.In many cities now some streets are closed to vehicles(机动车)and pedestrians are safe there.In London there is another experiment: part of the street is for buses only, so the buses can travel fast.There are no cars or taxis in front of them.
