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 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” .
Para. 1
Main idea: I'm about to travel along Qinghai-Tibet Railway.
How does the author describe Qinghai-Tibet railway
Para. 2
I was one of the people who 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 the most difficult engineering challenges. How to protect the delicate ecosystem was among the top concerns.
Main idea: How to protect the delicate ecosystem was the top concerns of various difficult engineering challenges.

What was the biggest challenge
What do you think author will talk about next
What are the challenges
How to overcome the challenges
Para. 3
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.
Main idea: Thirty-three passages were built under Qingshuihe Bridge to allow animals move safely and freely.

Para. 4
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.
Main idea: 675 bridges were built to prevent damage to wetlands and grasslands.

solutions
Para. 5
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.
Main idea: Several oxygen-making stations were constructed for railway workers.
challenge
solutions
Para. 6
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.
Main idea: A twenty-kilometre wall along the lake were built to protect Cuona Lake from construction waste.
