我们都吃过美味的铜锣烧,一种很可口的双层点心,它也是机器猫的最爱。这种食品上下两层清清楚楚,所以称之为双层夹心饼。但是,如果我说自然界有一个湖,也是上下两层,互不干扰,你能相信吗?而且更奇怪的是,这样的一个湖,上层是淡水,下层却是咸水,咸淡各流各的,你说奇怪不奇怪!这就如同是鸡尾酒一样,同样都是液体,但完全不混,仿佛中间有一层无形的薄膜将其隔开。呵呵,这不是天方夜谭,是自然界真实存在的,那就是位于美国的努沃克湖。 We all had delicious Dorayaki, a delicious double decker, and a favorite of the cats. This food clearly two layers, so called double sandwich cake. But if I say there is a lake in nature and there are two layers above and below each other, can you believe it? And what is more weird is that such a lake has freshwater on the upper level, saltwater on the lower level, It’s not surprising that you’re strange! It’s like a cocktail, the same liquid, but totally unmixed, with a layer of invisible film separating it. Oh, this is not a fantasy, is the real existence of nature, that is located in the United States Nuruwka.
