人人都知道粗心是我们生活中最危险的敌人，但有时我们并没有意识到自己的粗心。所以三思而后行是有必要的。一个月前，我就深受粗心之苦。一天我去姑姑家，妈妈嘱咐我带把伞以防下雨。我含糊地答应着，没拿伞就走了。在我回家的路上，果真下起了雨。我淋了雨，结果病倒了，害得我在床上躺了半个多月。
Everybody knows that carelessness is the most dangerous enemy in our life. But we sometimes can't realize it. So it is necessary to think twice when starting to do something. I suffered from my carelessness a month ago. One day I was going to my auntie's home, mom told me to bring an umbrella in case it mined. I answered casually and went out without taking the umbrella. But on my way back, I was caught in the rain and fell iii. I could do nothing but stayed in bed for half a month.
