The Advantage of Bicycle Riding
「骑单车的好处」

　　Bicycle riding has many advantages. It is the least expensive way of traveling apart from walking. If you travel by bicycle, you don't have to buy gas as you must when you drive cars. Besides, it develops much less mechanical troubles than a car.

　　bicycle riding is especially good for health. It is good exercise. If you go to work by riding a bicycle instead of driving or taking a bus, you can have a better chance of getting enough exercise you need everyday. Bicycling is also good for our environment. It is less noisy and does not pollute the air. I am glad to have ridden a bicycle to school when I studied in the high school.
