大学英语作文:骑单车的好处
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.
