【正确答案】The bicycle is the most common means of transport in our country. There are several reasons. First, most people are not rich enough to buy a car. Because a bicycle is not expensive, almost every family can afford it. Second, China has a large population and the traffic is heavy. The bicycle has the advantage of being small. A road, which can hold only two cars side by side, can allow more than ten bicycles. Finally, people like to ride on a bicycle to school, to work and to travel. It's so pleasant and it does good for people's health.
Compared with a car, a bicycle has disadvantages and advantages. For instance, a bicycle is not fit for a long trip, but a car is. A person who sits all day in a car might get fat and unhealthy, while a person on a bicycle becomes healthy.
A bicycle is so popular in China that it will remain so for a long time. So many things are to be done to make cars popular in China. Even when the time comes, bicycle will also be welcome.
