The first landmark to catch my eye 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. Thirty-three passages have been built under the railway to allow the animals to move safely and freely in their natural habitat. 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 hour.
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。

To prevent damage to wetlands and grasslands, 675 bridges with a total length of 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.
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。
Para. 4
The journey has been flying by, and before I know it, we have reached Tanggula Station. Located at over 5,000 metres above sea level, this is the highest railway station in the world. In locations such as this, the thin air, changeable weather and high levels of UV radiation 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.
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。
Para. 5
As we pass Cuona Lake, I feel a sense of pride and achievement. Using thousands and thousands of sandbags, we built a twenty-kilometre wall along the lake to protect it from construction waste. Cuona Lake is so close to the railway that I want to reach out and touch its pale blue mirror-like surface. Water birds playing in the lake, and cattle and sheep wandering the grasslands bring the scenery to life.
