T or F
Read the para.1 and answer the questions:
impossible

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”.
“一條條巨龍翻山越嶺”
黃昏我站在高高的山崗 盼望鐵路修到我家鄉
一條條巨龍翻山越嶺 為雪域高原送來安康
3．According to the text，what is the writer
A．A traveller.
B．A worker on the train.
C．A wildlife protector.
D．A construction worker.
4. When building the railway, engineers take ecosystem into consideration.
(True or False)
T
Read the para.2 and answer the questions:
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.
“記錄了我們克服最困難工程所做的一切努力”
5. What measure was taken to protect wild animals
A. Building the world's longest bridge.
B. Building passages under the railway.
C. Forbidding hunting the wild animals.
D. Moving the wild animals to the fixed areas.
Read the para.3 and answer the question:
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.
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.

8. What is NOT the challenge for the workers in Tanggula Station
A．Thin air. B．Changeable weather.
C．UV radiation. D．Breaks.
7. Tanggula Station was the (high)railway in the world.
highest
Read the para.5 and answer the question:
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.
9. What was done to protect Cuona Lake
A. Building a wall along the lake.
B. Building a passage along the lake.
C. Building a bridge across the lake.
D. Forbidding building any building along the lake.
Read the para.6 and answer the question:
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.
10. What makes the author feel proud
A. We built the"impossible"railway.
B. We protected the ecosystem.
C. We built the“impossible"railway,not destroy the ecosystem.
D. Passengers call it "Sky Railway".
Read the para.7 and answer the question:
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”.
