Nowadays more and more Chinese go to work with bicycle, leaving their cars at home. Why are so many people riding bicycles to work? They have different reason for it.
First, bicycles do not use up any fuel. Therefore, they cost less than other means of transport. Besides, bicycles do not need many space on the road, and it is easily to find a place for it. And everybody knows that riding a bicycle is healthy sport.
When people drive their cars to work or shop, they lost the chance to exercise, but the waste gas from the cars will pollute the air. And moreover, people feel annoying when looking for a parking lot in the busy city center. So I prefer riding a bicycle to drive a car.
We are looking forward to a cleaner and better environment by changing our life style.
