Describe the most efficient transportation in your country. （06. 4.8; 06. 12.15考题）

Sample answer：

The most effective means of transport, I'd say, is bicycle, an indispensable companion of most Chinese even though the private cars are on the rise. Each Chinese family possesses at least one bicycle and it is especially popular among college students. Compared with cars, bicycle still has some advantages. First, it is very convenient due to its small size. It does not need special parking space and can be parked almost everywhere. Second, driven by man power, it doesn't need fuel, so it has nothing to do with air pollution and energy crisis. Third, most people can afford a bicycle, but not a more advanced car. With so many advantages, bicycle will remain to be the most effective means of transport in China in the following years.
