When I was eight, my father bought me the new bike for my birthday. My brother offered to taught me how to ride. At first, he rode and let me watching. Then he explained me the skills of controlling the bike. Still puzzling, I got on the bike, but it didn’t move as expected. I lost my balance and fall off the bike. At once I burst into tear because I saw blood on the ground. While I stood up, my left leg hurt bad. Later, I learned to ride a bike. This experience told me that though some lessons were painful to learn them, yet we could benefit a lot.
