无尽的夏天(Endless summer)

别把太阳镜弄丢了！至少在挪威斯瓦尔巴特岛每年的这个时候，太阳升到地平线上，并且在五个多月内再也不会下降到地平线以下。从大约4月19日到8月23日，在挪威大陆以北500多英里的北极圈上空的这个岛屿上，除了阳光什么都没有。海滩上的天气不太好，夏季的平均高温为39到45华氏度（相比之下，冬季的平均温度为5到9华氏度）。谁知道离最近的太阳镜店有多远？

Don’t lose your sunglasses! At least not during this time of year in Svalbard, Norway, when the sun crests the horizon and never dips below it again for more than five months. From about April 19 to August 23, it’s nothing but sunshine on this island above the Arctic Circle, more than 500 miles north of mainland Norway. It’s not quite a day at the beach, with average summertime high temps of 39 to 45 degrees Fahrenheit (toasty compared to average wintertime temps of 5 to 9 degrees). And who knows how far it is to the nearest sunglasses store?
