(sit) back in my seat, I can't believe that I'm about to travel along the railway that many foreign experts claimed was "impossible". The train has been racing along (steady) since it left Xining.
I was one of the people came from all parts of China to work on this railway. Taking years to complete, the Qinghai Tibet Railway is a record of all of our efforts to overcome most difficult challenges. How (protect) the ecosystem was among the top concerns. The first landmark (catch) my eye is the Qingshuihe Bridge, the world's longest bridge built over permafrost. To prevent damage to wetlands and grasslands, 675 bridges (build) between Golmud and Lhasa.
Tanggula Station, (locate) at over 5,000 metres above sea level, is the highest railway station in the world. To make sure we stayed healthy, several oxygenmaking stations were constructed. Passing Cuona Lake, I feel a sense of pride and (achieve). Along the lake we built a twentykilometre wall to protect the lake construction waste.
I'm proud that we built our "impossible"railway. It truly is an extraordinary "Sky Railway".
