| When I was about 12 years old, I really wanted a new bike! I 1 my parents my birthday wish, but I knew there was little hope because my family could 2 have that money. On my birthday my parents told me they had my 3 outside in the back yard. At once I 4 out to the yard. There was my bike, 5 it wasn't the bike that I thought it would be. This one was pink, old and worn with age. It was so 6 ! I thought I 7 my parents' feelings because I could see the disappointment 8 their faces and I was sure they could see it on mine. I 9 the old bike and rode it, feeling 10 that I had made my parents feel this way. So I put on a smile, rode as fast as I could and didn't 11 ... As time went by, I began to understand my parents gave me 12 much more than just a rusty (生锈的) old bike. They gave me a life lesson about 13 . When you give something out of love, it doesn't matter what it is in fact. What matters is the love that is in it. I like to remember this 14 because giving a gift is not about money. It's about how much love you can feel from it. Do remember, a gift that 15 two dollars isn't any less valuable (有价值的) than one that costs one hundred dollars, or even more. | ||||
