范文：
The bicycle is the most common means of transport in our country. There are several reasons for that. First， most people are not rich enough to buy a car. Since the bicycle is not expensive， it is affordable by the average Chinese families. Second， China has a large population and the traffic is heavy. The bicycle has the advantage of being small in size. A road which can only allow two cars to pass may allow more than ten bicycles to run side by side. Finally， people enjoy riding a bicycle to school， to work and on outing. It is so pleasant and the exercise is good for people's health.
Compared with a car， a bicycle has its disadvantages and advantages. For instance， a bicycle is not fit for a long distance trip. A person who sits all day long in a car might get fat and unhealthy， while a person on a bicycle may gain good health and pleasure.
The bicycle is popular in China and it will remain so for a long time to come. Many things must change before cars became common in China. Therefore， in the foreseeable future， the bicycle will still be welcome.
