                                                      Bicycles in China

     Bicycles are very popular in China. In our country you can see bicycles almost everywhere. When you

walk on the road, you will find a lot of people riding bicycles to school, shops and anywhere else. Therefore

(因此), China is known as "the kingdom of bicycles". In China, many families have one or two bicycles.

     Compared (与……比) with cars, bicycles have many advantages. First, they are much cheaper than cars.

Most Chinese can't afford cars, but they can afford bicycles. Second, bicycles are small enough to park

anywhere, while cars need a larger piece of land to park. What's more, with lower speed, bicycles are safer

than cars.

     However, bicycles also bring some problems. Some riders don't obey the traffic rules and some riders

don't think about others' safety. So they ride too fast. During rush hours, too many bicycles may cause traffic

jams. We still have a long way to go to solve the problem.
