The price of public transportation in Beijing has doubled twice since 1989, but it is still a bargain. Using the subway and minibuses used to show class status; now people of all classes take them, while some wealthy prefer taxis or private cars. What a change in just a few years ! But there are downfalls to having more cars on the roads. Fortunately, the government is aware of the problem. No-lead gasoline is the only one permitted in the city, and the rest of the country follows. Thousands of trees are planted in and around the city every year. Children are taught why and how to protect the environment. At the same time, public transportation has marked real progress: buses are everywhere and run frequently. We no longer see those old buses with broken windows. Instead, there are fast buses, double- decker buses, air-conditioned or heated buses, all offering a good service.

Some cities have planned their transportation systems for ear owners. That is what Los Angeles did. Los Angeles decided to build highways for cars rather than spending money on public transportation.
This decision was suitable for Los Angeles. The city grew outward instead of upward. Los Angeles never built many tall apartment buildings. Instead, people live in houses with gardens.
In Los Angeles, most people drive cars to work. And every car has to have a parking space. So many buildings where people work also have parking tots.
Los Angeles also became a city without a Central Business District (CBD). If a city has a CBD, crowds of people rush into it every day to work. If people drive to work, they need lots of road space.
So Los Angeles developed several business districts and built homes and other buildings in between the districts. This required more roads and parking spaces.
Some people defend this growth pattern. They say Los Angeles
A. there is no public transportation system
B. more money is spent on highways for cars
C. more money is spent on public transportation systems
D. public transportation is more developed than in other cities
