Have you ever heard this song
What is the song sing about
If possible, which means of transportation would you choose to travel to Tibet
How much do you know about Qinghai-Tibet Railway
Work in pairs and complete the quiz.
Try to guess if you are not sure of the answers.
1 Which is the highest railway in the world
a The Trans-Siberian Railway.
b The Qinghai-Tibet Railway.
c The Chengdu-Kunming Railway.
2 In which year was the completed Qinghai-Tibet Railway put into operation
a 1984.
b 2001.
c 2006.
3 Which of these stations is not on the Qinghai-Tibet Railway
a Lhasa.
b Golmud.
c Lanzhou.
4 Which of these natural World Heritage Sites does the Qinghai-Tibet Railway pass by
a Xinjiang Tianshan.
b Qinghai Hoh Xil.
c South China Karst.
The Qinghai-Tibet Railway, 1,956-kilometer-long, which began service in July 2006, is the world’s highest and longest plateau(高原) railroad and also the first railway connecting the Tibet autonomous region with other parts of China.
The Qinghai-Tibet Railway is a symbolic project in China's West Development Strategy and will play a significant role in accelerating the social and economic development of Qinghai Province and Tibet Autonomous Region.
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".
P1： The author felt excited to start his journey on the “Sky Railway”.
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.
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 animal 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.
P2:People completed the Qinghai-Tibet Railway by overcoming the most difficult engineering challenges.
P3: Passages have been built under the railway to allow animals to move safely and freely in their natural habitat.
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.
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.
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.
P4:Effective measures were taken to prevent damage to wetlands and grasslands.
P5:To make sure the railway workers stayed healthy, several oxygen-making stations were constructed.
P6:A twenty-kilometre sandbag wall along the Cuona Lake was built to protect it from construction waste.
7 The Qinghai-Tibet Plateau 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".
P7:We built our “impossible” railway with the care the environment deserves.
Read the passage and find out why the railway is particularly special to the author.
