“What's the matter, mum?” When I came home yesterday, I found my mother was unhappy. It was unusual—she usually opened the door and welcomed me with a smile. “She's dying (死),” mum said sadly. I knew what she said. The tulip (郁金香), mother's favorite, was dying.
   A month ago, we moved into our new house and mum bought a very beautiful tulip. Mum liked it very much. Every time she was free, she would sit near the tulip and enjoyed its beautiful color and nice smell. She treated (对待) it like a baby and looked after it carefully. She put the tulip by window and moved it from one place to another to give the tulip enough sunshine. Every morning the first thing she did was to water the tulip. Mum also fertilized (施肥) it many times. She hoped the tulip would become more and more beautiful and stronger. But the tulip was dying because of too much sunshine, water and fertilizer.
   It's true that mother loved the tulip. But this kind of love can be harmful (伤害的). Love can sometimes kill (杀害) what you love.
