Part of the problem, I think, is we stand at the beach, or we see images like this of the ocean, and you look out at this great big blue expanse, and it's shimmering and it's moving and there's waves and there's surf and there's tides, but you have no idea for what lies in there.
当你站在海滩上 或是当你看到海洋里的图像， 当你看着这么一大片蓝色，它泛着光， 不断地变动着，一会儿是海浪，一会儿是波涛， 一会儿又涨潮， 你却不知道它里面到底有些什么。
