十一月中,华北平原已经冷了,几股寒流一过,温度稀里哗啦地掉下来。华北人民这些年已经接受了一个现实:每年十月下旬,雾霾就开始出现,到十一月大张旗鼓地铺陈着,天天看着苍白的太阳在朦胧中东升西落,只能等着冷空气南下才能把笼罩数日的雾霾吹开,让新鲜的空气暂时占领天地。新鲜空气的出现也往往伴生着寒冷,所谓“鱼与熊掌不可兼得”的现实版就在雾霾这个问题上得到了生动的表现。 In mid-November, the plains of North China are already cold, and after a few cold spells have passed, the temperature drops off sparsely. The people of North China have already accepted the reality these years: the haze begins to appear in late October each year, and in full swing in November, the pale sun rises and falls in the hazy Middle East every day, waiting for cold air to go south In order to blow the haze enveloped a few days, so that fresh air temporarily occupied the world. The emergence of fresh air often accompanied by cold, the so-called “can not have both fish and bear’s paw,” the reality version of the fog on the issue of haze has been vividly demonstrated.
