Part Four: Monologue
The public transportation systems in most big cities in America are very good. New York, especially, has one of the largest and most useful subway and bus systems in the world. Public transportation helps to cut down on pollution and traffic. In big cities, with so many people, this is a very important problem. However, Americans do love their cars. The average family has two.  So much more money goes into building roads, than new subway or train lines.  In some cities, like Atlanta, this has meant a quick increase in pollution and traffic congestion as its population has grown.
在美国的大城市里，大多数都有很齐全的公共交通系统。尤其是纽约拥有的市内地铁和公交车系统就是全世界最大、利用率最高的地区之一。公共交通系统可以减少污染和缓解交通负担。对于人口众多的大城市，这是个非常重要的问题。然而，美国人是爱车的。平均每个家庭的小汽车拥有量为两辆。因此用于修建公路的资金往往比用于修建新的地铁线和火车线路的资金多得多。在象亚特兰大这样的一些城市，随着人口的增加，也同时意味着污染和交通阻塞的日益严重。
