今天,我在家属楼下面打羽毛球,也不知道是哪家住户往楼下扔了一袋垃圾,要不是妈妈叫我往旁边站,我准得被这袋垃圾砸着。回到家,我想了想,楼上这些住户也真是的,虽然楼下有垃圾车是给大家扔垃圾准备的,可也不能从楼上往楼下扔啊!不就是上上下下多走点路吗?如果每户人家每天要丢1袋垃圾的话,那我们家属院3栋楼,每栋5层楼,3个单元,每层2户,一共就:2×3×5×3=90袋垃圾,一个月就2700袋垃 Today, I play badminton under the stairs of a family member. I do not know which household dropped a bag of rubbish downstairs, or if my mother asked me to stand next to me, I would have been smashed by this bag of rubbish. Back home, I thought, these tenants upstairs is also true, although the garbage truck downstairs is ready for everyone to throw garbage, but also can not throw downstairs from upstairs ah! Road? If every household every day to lose 1 bag of garbage, then our family hospital 3 buildings, each 5 floors, 3 units, 2 per floor, a total of: 2 × 3 × 5 × 3 = 90 Bag garbage, a month on the 2700 bags of garbage
