天路
靠坐在火车的座位上，我简直不敢相信，我将要沿着许多外国专家声称“不可能建成”的铁路旅行。火车从西宁出发，向前平稳行驶。一路上，《天路》这首歌一直在我的脑海中回响。当火车开过“世界屋脊”时，“一条条巨龙翻山越岭”的歌词显得格外生动鲜活。
修建青藏铁路的工人来自全国各地，而我就是其中之一。它历时数年建成，凝聚着我们攻克种种工程难题的全部心血。其中，如何保护脆弱的生态系统是需要我们首要问题之一。
最先映入眼帘的地标性建筑是壮观的清水河大桥，它是世界上最长的高原冻土铁路桥。看！一群藏羚羊正从桥下走过，有的停下来悠闲地吃草。铁路桥下修建了三十三条野生动物通道，让动物得以在自然栖息地中安全自由地通行。就像现在的这群藏羚羊一样，野生动物们使用这些通道已有数年，它们似乎完全没有意识到我们正以每小时100多千米的速度呼啸而过。
为了避免破坏湿地和草原，我们在格尔木和拉萨之间建造了675座大桥，总长度约160千米。我们甚至将一块14万平方米的湿地迁往一个新的区域，以保护其独特的生态系统。
火车一路疾驰，还没等我反应过来，我们就已经到达了唐古拉车站。它位于海拔5,000多米的地方，是世界上海拔最高的火车站。在这样的高海拔环境中，稀薄的氧气，多变的天气，还有强烈的紫外线辐射，这些恐怕是我们铁路工人面临的最大挑战。为了确保工人的身体健康，我们建造了多个制氧站。我们还会定期到低海拔地区休整。
火车经过措那湖时，一股自豪感和成就感在我心中油然而生。当年，我们沿着措那湖边用成千上万个沙袋筑起了一道二十千米的保护墙，使它免受建筑废料的污染。现在，措那湖离火车这么近，我好想伸手去触摸它那镜面似的浅蓝色湖面。湖中嬉戏的水鸟，在草原上游荡的牛羊，让这片风景充满勃勃生机。
几个世纪以来，青藏高原是无数人向往的地方。如今，由于我们的努力，来自全国各地的旅客都能亲眼观赏到这片神奇的土地。我们建成了一条“不可能建成”的铁路，并且给予当地环境充分的保护，我为此感到骄傲和自豪。青藏铁路真是一条了不起的“天路”。
