Activity 3 Detailed-reading 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. Para. 3 Activity 3 Detailed-reading Challenges Solution To protect wild animals. 1 ___________ have been built under the railway to allow the animals to 2 ________________ ____________. 33 passages move safely and freely Do you think the solution works well? Why? 4 To prevent damage to wetlands and grasslands, 675 bridges with a total length of about 160 kilometres were built between Golmud and Lhasa.

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. Para. 5 Activity 3 Detailed-reading Challenges Solution To make sure the workers stayed healthy. 6 _______________________ were constructed. The workers also enjoyed 7 _______________ in lower areas. Several oxygen-making stations regular breaks Is working on construction site of the Qinghai-Tibet Railway dangerous? 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.

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”. Para. 7 Activity 3 Detailed-reading not only because the highest / the toughest railway to build but also because a railway of development a railway of life a railway of unity a railway of happiness ... Task 10. Why is the Qinghai-Tibet Railway called the Sky Railway? What changes do you think the Qinghai-Tibet Railway has brought to the people living along the railway? Think&Share It has helped to boost the local economy. The opening of the Qinghai-Tibet Railway thoroughly broke the long-term transport bottleneck restricting Tibet. More and more specialties of Tibet have been transported to the hinterland(内地) by the railway and sent to the world. The average annual growth rate of Tibet’s GDP from 2006 to 2014 exceeded 10 percent. Activity 4 Post-reading It has improved people’s living standard. The farmers and herdsmen (牧民) along the Qinghai-Tibet Railway have taken the “railway business opportunity“ to increase their income. Large numbers of quality and cheap goods have been transported to Tibet via the Qinghai-Tibet Railway, improving Tibet People’s production and living standards. It has made it more convenient for people to travel. The Qinghai-Tibet Railway passes many famous scenic areas such as the Qinghai Lake, Kunlun Mountains, Hoh Xil and Northern Tibet Grassland, forming a world-class tourist route full of mysterious flavor. Over the past nine years, Tibet’s tourism has seen “blowout-type” development and become a pillar industry. Tibet has received all together 74 million domestic and foreign tourists. ONE ON ONE programme is having an interview with the railworker ---the author of the text. Design an interview and act it out.
