Write a composition of about 150 words on the following topic：
Bicycle
Bicycles have become more and more popular in China. People ride bikes to their work places， to shopping areas， to schools， and so on. During the rush hours， you can often see a boiling sea of bicycles running in all directions. With the largest number of bike riders in the world， China is often referred to as the kingdom of bicycles.
All are not friends that speak us fair.
说我们好话的未必全是朋友。
Compared with cars， bikes have many advantages. First， they are not very expensive， and almost every family can afford them. Second， they are very handy and convenient though they are not so fast as cars. With a bike， you can go anywhere you like， and you don’t have to look for a large parking place. By riding bikes， you can avoid traffic jams and thus save the time and the money for taking taxis. Third， they do not cause air or sound pollution.
Riding bikes does good to your health if you ride it regularly. In modern times， people are usually too busy to spare any time for physical exercise. Riding a bike to your work place regularly serves as a good way to keep yourself strong and healthy.
Therefore， a bicycle is really an important means of transportation in China. It has been very useful， convenient and necessary ever since it was invented. And I do believe it will still be so in the future.
