当我们到达一个陌生的国度,该如何分辨它是否发达?或许最好的方法就是等待一场倾盆大雨,足足下几个小时。这时如果你撑着伞在街道上走一阵,发觉衣衫湿了却不肮脏,街道湿滑却不积水,交通缓慢却不拥堵,这大概就是对发达国家的印象。如果积水盈足,交通停滞,汽车的零件都漂到了街心,这大概就是个发展中国家。2012年7月21日,北京遭遇罕见暴雨,是自1951年有完整气象记录以来的最大降水量。造成数十人死亡,数万人受灾,一时间偌大的北京城陷入了暴雨之殇,也再次验证了京城排水设施的脆弱。 When we arrive in a strange country, how can we tell if it is developed? Perhaps the best way is to wait for a heavy rain, for a full few hours. At this time, if you walk on the streets with your umbrella, you will find that the clothes are wet but not dirty, the streets are slippery but there is no water, and the traffic is slow but not congested. This is probably the impression of the developed countries. If the water is full, the traffic is stagnant, and the parts of the car drift to the heart of the street. This is probably a developing country. On July 21, 2012, Beijing experienced rare rainstorms, which is the largest precipitation since a complete meteorological record in 1951. Dozens of people were killed and tens of thousands of people were affected. Beijing City, which was once very large, was caught in a rainstorm, and once again verified the fragility of the drainage facilities in the capital.
