Section 1　Starting out&Understanding ideas—Prereading 原|文|诵|读 The Sky Railway 1．Sitting back in my seat, I can't quite believe that I'm about to travel along the railway that many foreign experts claimed was “impossible”. The train has been racing along ① since it left Xining. All this time, the song “Sky Railway” has been playing inside my head. The words “railways like ② dragons are ③ among the mountains” seem particularly vivid as I travel across the “roof of the world”． 2．I was one of the people who came from all parts of China to work on this railway. Taking years to complete, the Qinghai­Tibet Railway is a record of all of our efforts to overcome the most difficult engineering challenges. How to protect the ④ ecosystem was among the top ⑤. 3．The first ⑥ to catch my eye is the ⑦ Qingshuihe Bridge, the world's longest bridge built over permafrost. Look! A group of ⑧ ⑨ is moving under the bridge, with some stopping to eat grass ⑩. Thirty­three 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. 4．To prevent damage to wetlands and grasslands,675 bridges with ⑪ of about 160 kilometres were built between Golmud and Lhasa. We even moved 140,000 square metres of ⑫ to a new area in order to protect its ⑬. 5．The journey has been flying by, and before I know it, we have reached Tanggula Station. ⑭ 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 ⑮ presented perhaps the greatest challenge for railway workers. To make sure we stayed healthy, several oxygen­making stations were constructed. We were also able to enjoy regular breaks in lower areas. 微|点|清|障 ①steadily /ˈstedɪli/ adv.平稳地 ②massive /ˈmæsɪv/ adj.巨大的 ③wind /wa
