几年前,大城市中几乎家家户户阳台上都栽着几盆菊花、月季,有的还配上常春藤、爬山虎,花季一到,绿肥红瘦,颇为热闹。时隔十年,当年风行的阳台、窗台、屋顶绿化已大道冷落,原因是:养花太费时间,居民每天上下班,没工夫伺候它们。 A few years ago, almost all households in the big cities were planted with pots of chrysanthemums and roses on the balconies of their homes, and some were also covered with ivy and ivy. A decade later, when the popular balcony, bay windowsill, green roofs have been neglected Avenue, because: spend too much time on the flowers, residents work every day, no time to wait for them.
