9 阅读理解。 For years I wanted a flower garden, but with five children I was too busy to have one. Money was limited, and so was time. Often one of the children would want something that cost too much, and I would say, "Do you see a money tree outside? Money doesn"t grow on trees, you know. "Finally, when all five had gotten through high school and college, and had started having their own families, I started thinking again about having a garden. However, I knew gardens cost money. Then, one spring morning on Mother"s Day, as I was working in my kitchen, I heard cars drive by and looked out of the window to see a new tree planted in my yard. I couldn"t believe my eyes: it was a money tree! Dollar bills were stuck all over that tree, and there was a note which read: "I owe you eight hours of digging time. Love, Marvin." Marvin, my first son, kept his promise. He dug up a nice ten-by-fifteen-foot bed (花坛,花圃) for me. My other children bought me tools, a sunflower stepping stone (踏脚石) and gardening books. We built a garden together. That was three years ago. My garden is now very pretty, and just what I"d always wanted. When I go out to weed or tend my flowers, I don"t seem to miss my children as much as I once did. It feels as if they were right there with me. When I think about what my children have done for me, I get tears in my eyes every time. I"m still not sure whether money grows on trees. But I know love does! 1.
