The Sky Railway
Sitting back in my seat [1]，I can't quite believe that I'm about to travel① along the railway that many foreign experts claimed was“impossible”．The train has been racing along steadily since it left Xining．All this time，the song“Sky Railway”has been playing inside my head．The words“railways like massive dragons are winding among the mountains”seem particularly vivid as I travel across the“roof of the world”．
[1]Sitting back in my seat是动词-ing形式短语作状语。
I was one of the people who came from all parts of China to work on this railway．Taking years to complete [2]，the Qinghai-Xizang Railway② is a record of all of our efforts to overcome the most difficult engineering challenges③.How to protect the delicate ecosystem was among the top concerns④.
[2]Taking years to complete是动词-ing形式短语作状语。
The first landmark to catch my eye⑤ is the splendid Qingshuihe Bridge，the world's longest bridge built over permafrost．Look! A group of Tibetan antelopes is moving under the bridge，with some stopping to eat grass at their leisure [3].Thirty-three passages have been built under the railway to allow the animals to move safely and freely in their natural habitat⑥.Wild animals such as these Tibetan antelopes have now been using these passages for years．They seem totally unaware that we are speeding past at over 100 kilometres an hour⑦.
[3]此处是with复合结构作状语，表示伴随。
To prevent damage to wetlands and grasslands[4]，675 bridges with a total length of⑧ about 160 kilometres were built between Golmud and Lhasa．We even moved 140，000 square metres of wetland to a new area in order to protect its distinct ecosystem．
[4]此处是不定式短语作目的状语。
The journey has been flying by，and before I know it[5]，we have reached Tanggula Station⑨.Located at over 5，000 metres above sea level [6]，this is the highest railway station in the world．In locations such as this，the thin air，changeable weather and high levels of UV radiation⑩ presented perhaps the greatest challenge for railway workers．To make sure we stayed healthy ，several oxygen-making stations were constructed．We were also able to enjoy regular breaks in lower areas．
[5]before引导时间状语从句，意为“在……之前”或“还没来得及……就……”。
[6]Located at over 5，000 metres above sea level是形容词短语作状语。

天路
靠坐在火车的座位上，我仍然不敢相信，我将要沿着许多外国专家声称“不可能建成”的铁路开始一段旅程。火车从西宁出发，向前平稳行驶。一路上，我的脑海中不断回响起《天路》这首歌曲。当火车开过“世界屋脊”时，“一条条巨龙翻山越岭”的歌词变得更加生动鲜活起来。
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高度重视的问题之一。
最先映入眼帘的地标性建筑是壮观的清水河特大桥，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，有的则停下来悠闲地吃草。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，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，氧气稀薄，天气多变，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。因此建造了多个制氧站以确保工人的身体健康，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，沿着措那湖边，我们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，措那湖离铁路这么近，我好想伸出手去摸一摸它那镜面似的浅蓝色湖面。在湖面上嬉戏的水鸟，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，由于我们的付出，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，我为此感到自豪。青藏铁路真是一条了不起的“天路”。
