很多年前的一个秋日的下午，我独自去了一座老宅。老宅的院里长着几株挺拔的枫树，在秋风中飒爽地挥舞着艳丽的红衫。整个院子都弥漫着它淡雅的枫香。阳光从闪动的叶子间漏了下来，斑斑驳驳的，像花一样嵌在树下的石桌及地上碧绿碧绿的青苔上。青苔很完整，没有刺眼的白斑。显然，这老宅必是许久没有人居住了。再看围墙，剥落得厉害，和攀附在它身上的紫葡萄藤一样。《消失的地平线》叙述了一群有志青年的奋斗历程，以他们的求学之路为时间线索，描写了他们成长、成熟的历程。On an autumn afternoon many years ago, I went to an old house alone. In the courtyard of this old house, there are a number of tall maples whose red leaves are dancing in the wind. The whole courtyard is full of light fragrance of maple. The sun casts lights through dancing leaves, showing mixed colors or tints, like flowers embedded on stone table and green moss. Moss is complete, without dazzling white spots. It is obvious that this old house has been uninhabited for a long time. Look at the fence, it is badly peeled off, like purple vine climbed on itself. No Line on the Horizon describes the struggling course of a group of young people, takes their studying course as time clue, and tells about their growing and mature process.
