[3]How to protect the delicate⑧ ecosystem[4]was among the top concerns⑨. [3]本句为简单句。Taking years to complete为动词-ing形式短语作状语，take与其逻辑主语the Qinghai-Xizang Railway之间为主谓关系，故用动词-ing形式。动词不定式短语to overcome...challenges在句中作后置定语，修饰名词efforts。 [4]画线部分为“特殊疑问词＋不定式”结构，在句中作主语。 3 The first landmark⑩ to catch my eye⑪ is the splendid⑫Qingshuihe Bridge，the world's longest bridge built over permafrost⑬．[5]Look！A group of 学生用书第143页 Tibetan⑭ antelopes is moving under the bridge，with some stopping to eat grass at their leisure⑮．[6]Thirty-three passages⑯ 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 speeding⑰ past at over 100 kilometres an hour. [5]本句为简单句。因landmark前有序数词The first 修饰，故此处用动词不定式短语作后置定语。the world's...permafrost为Qingshuihe Bridge的同位语，其中built over permafrost为动词-ed形式短语作后置定语，修饰名词bridge，bridge与build之间为逻辑上的动宾关系。 [6]画线部分为with复合结构，some在此作宾语；动词-ing形式短语stopping to eat grass at their leisure在此作宾语补足语，stop与其逻辑主语some之间为主谓关系。 4 To prevent damage⑱ to wetlands and grasslands，675 bridges with a total length⑲ 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 to⑳ protect its distinct ecosystem. 5 The journey has been flying by，and before I know it，we have reached Tanggula Station.Located㉑ 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，changeable㉒ weather and high levels of UV radiation㉓ presented perhaps the greatest challenge for railway workers.To make sure㉔ we stayed healthy，several oxygen-making stations were constructed㉕.We were also able to enjoy regular breaks in lower areas. 6 As we pass Cuona Lake，[7]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 out㉖ and touch its pale blue㉗ mirror-like㉘ surface.[8]Water birds playing in the lake，and cattle and sheep wandering the grasslands bring the scenery㉙ to life㉚.[9] 学生用书第144页 [7]As引导时间状语从句。 [8]本句中包含“so...that...”结构，引导结果状语从句。 [9]本句为简单句。动词-ing形式短语playing in the lake和wandering the grasslands在句中作后置定语，分别修饰名词短语Water birds和cattle and sheep。 7 The Qinghai-Tibet Plateau㉛ has been attracting people's admiration for centuries.Now，thanks to our efforts，passengers from all over the country have been enjoying these magical landscapes.I am proud that we built our “impossible” railway，and did so with the care that the environment deserves.It truly is an extraordinary “Sky Railway”． [文化采风] 清水河特大桥(Qingshuihe Bridge)位于可可西里自然保护区，全长约11.7千米，是青藏铁路线上最长的“以桥代路”特大桥，也是世界上最长的建在永久冻土层上的桥。 清水河特大桥如同一条美丽的“彩虹”，飞架于昆仑雪山下。为了解决高原冻土区施工难题并保护好自然保护区，青藏铁路勘察设计的专家采取了“以桥代路”的措施。“以桥代路”解决了高原冻土地带路基不稳定的问题，同时，大桥各桥墩间建的桥孔还为藏羚羊等野生动物提供了自由迁徙的通道。 ………………………………………………………………………………………◎ 天路 坐在座位上，我不太敢相信自己将要沿着被许多外籍专家称为“不可能”的铁路旅行。火车离开西宁以后，全程都在平稳快速地前进。《天路》这首歌一直在我脑海里萦绕。穿越“世界屋脊”时，“一条条巨龙翻山越岭”这句歌词显得尤为生动。 我是来自中国各地、参与这条铁路建设的人员之一。青藏铁路历时多年建成，记录了我们为克服最为艰巨的工程方面的挑战付出的所有努力。如何保护(这里)脆弱的生态系统是最重要的事情之一。 第一个吸引我注意的地标是壮丽的清水河特大桥，世界上建在永久冻土层上的最长的桥梁。快看！一群藏羚羊正在桥下移动，有些在空闲时停下来吃草。铁路下面建造了33条通道，让这些动物在它们的自然栖息地可以安全、自由地移动。像藏羚羊这样的野生动物使用这些通道已经有很多年了。它们似乎完全没有意识到，我们正以每小时100多千米的速度飞驰而过。 为了防止对湿地和草原造成破坏，人们在格尔木和拉萨之间修建了675座桥梁，总长约160千米。为了保护此处独特的生态系统，我们还将14万平方米的湿地转移至新的区域。 (乘车的)时间过得飞快，不知不觉中，我们已经到达唐古拉站。这是世界上最高的火车站，位于海拔超过5 000米的地方。在这样的地方，稀薄的空气、多变的天气和高强度的紫外线辐射可能是铁路工人面临的最大挑战。为了确保我们的健康，人们建造了几个制氧站。我们也可以定期去海拔低一点的地区休息。 我们经过措那湖时，我有一种自豪感和成就感。利用千千万万个沙袋，我们沿湖建了一堵长20千米的墙，以保护湖泊免受建筑垃圾的侵害。措那湖距离铁路真近，我都想伸手触摸它那如明镜般的淡蓝色湖面。水禽在湖里嬉戏，牛羊在草原上漫步，这让此处的风景充满生机。 几百年来，青藏高原一直广受人们的赞叹。现在，多亏了我们的努力，全国各地的乘客都能欣赏到这些神奇的景致。我为我们建造了世界上“不可能的”铁路而自豪，过程中我们也对环境给予了应有的关注。这的确是一条非同寻常的“天路”。 学生用书第145页 学科网（北京）股份有限公司 $
