When I was about 12 years old, I really wanted a new bike! I __36__ my parents my birthday wish, but I knew there was little hope because my family could __37__ have that money. On my birthday my parents told me they had my __38__ outside in the back yard. At once I __39__ out to the yard. There was my bike, __40__ it wasn’t the bike that I thought it would be. This one was pink, old and worn with age. It was so __41__! I thought I __42__ my parents’ feelings because I could see the disappointment __43__ their faces and I was sure they could see it on mine. I __44__ the old bike and rode it, feeling __45__ that I had made my parents feel this way. So I put on a smile, rode as fast as I could and didn’t __46__... As time went by, I began to understand my parents gave me __47__ much more than just a rusty（生锈的）old bike. They gave me a life lesson about __48__.
