躺下,闭上眼,我开始想象那一片蓝天,不知不觉进入梦乡…… 我梦见在一片蓝天下,我在蓝色的地球上行走。地球表面围绕着经纬线,12条经线连贯南北极,而纬线只有一条,环绕赤道。我行走在这条纬线上,不断经历着酷暑;尽管经度在不断变化,我却只见到一种风景。 Lying down, closing my eyes, I started to imagine that a piece of blue sky, unconsciously into my dreams ... I dreamed of walking on a blue globe under a blue sky. The Earth’s surface is surrounded by longitude and latitude lines, 12 longitude lines connecting the North and South poles, and only one latitude, around the equator. Walking on this latitude line, I am constantly experiencing extreme heat; I see only a landscape, despite the ever-changing longitudes.
