Bicycle--An Important Means of Transport in China
    There are several reasons why bicycle is so popular in China. To begin with, it is so cheap that every family can afford to buy one. Some families even have two or three of it. Secondly, it is so convenient that with a bicycle, you can go to any place you like. Besides, you don＇t have to find a parking lot in a crowded street or have a garage at home. Finally, cycling has become a kind of sport that many people enjoy.
    Compared with a car, a bicycle has both advantages and disadvantages. For instance, a car uses gas as its fuel, as aresult, it may cause air pollution. A bicycle, however, is pollution free. A long travel is surely not fit for a bicycle. But a person who sits all day long in a car might get fat and become unhealthy.
    I think that since bicycle is so popular in China, it will certainly remain so for a long time.  Many things are being done to make cars popular in China, but even when that time comes, bicycle will still be welcome.
