前几年我在家里的阳台上种植了几盆花草，同时从别人那里移植来了一只仙人掌。由于经常记不得浇水，或是天寒没有将花移进屋内，后来，几盆花干的干，死的死，只剩下一盆仙人掌，依然绿得很旺。近一个月来，天气炎热，不下一丝雨，我也不曾为仙人掌浇过水。我以为阳台上那盆仙? A few years ago I planted potted plants and flowers on the balcony of my home while transplanting a cactus from somebody else. Because often can not remember the watering, or ascended the flowers did not move into the house, and later, a few dried pot of dried flowers, death, leaving only a pot of cactus, is still very green. The past month, the weather was hot, no less than a trace of rain, I have never poured water for the cactus. I think that sink pot on the balcony?
