When I was eight, my father bought me the new bike for my
birthday. My brother offered to teach me how to ride. At first, they rode and
let me watching. Then he explained me the skills of controlling the bike. Still
puzzling, I got on the bike, but it doesn'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. But this experience told me that though some lessons were painful to
learn them, yet we could benefit a lot.
