When I was very small, I felt so envious to see the children riding bicycle, I thought they were so cool. So I tried so hard to learn how to ride it. I still remembered the day when I could ride bicycle and I was so proud. Today, bicycle is still my favorite transportation. On the one hand, I can exercise my body. I ride the bicycle to go to school, it is true that I do have the strong body, because I barely feel sick. On the other hand, riding the bicycle can protect our environment. Bicycle works with our legs instead of the gasoline. The gasoline burns and it lets out the air which can pollute our environment. So taking the bike is a good way to protect our environment. I think I will continue to keep bike as my favorite transportation.
