Tucked away in our subconscious is an idyllic vision. We see ourselves on a long trip that spans the continent. We are traveling by train. Out the windows, we drink in the passing scene of cars on nearby highways, of children waving at a crossing, of cattle grazing on a distant hillside, of smoke pouring from a power plant, of row upon row of corn and wheat, of flatlands and valleys, of mountains and rolling hillsides, of city skylines and village halls. 我们的潜意识里藏着一派田园诗般的风光! 我们仿佛身处一次横贯大陆的漫漫旅程之中! 乘着火车, 我们领略着窗外流动的景色:附近高速公路上奔驰的汽车、十字路口处招手的孩童、远山上吃草的牛群、源源不断地从电厂排放出的烟尘、一片片的玉米和小麦、平原与山谷、群山与绵延的丘陵、天空映衬下城市的轮廓, 以及乡间的庄园宅第!
