At that time, we had a big yard in which a beautiful maple tree stood. But my mother often looked with 38 at this work of natural art. Those golden leaves seemed like tons of rubbish to her, “something else to 39 !”Seeing the neighbors busy with gardening, my father even thought it a waste of time. At that age, I always did something 40 to whatever my parents did!If gardening were something they found 41 , I would plant a garden! I planted some lily(百合花)seeds in the yard.

And now I could say it is my affection for 55 that makes me a real gardener.
