Building this railway was extremely difficult. The frozen ground in summer would melt and become too soft for construction. 2.______________ In some places, tunnels had to be created instead of building over the ground. Engineers came up with creative solutions. 3.______________ These pipes helped keep the ground hard. In other areas, bridges were built so that the railway could stay above the soft ground. 4.______________ Since its completion, the railway has greatly increased tourism and economic development in the region. 5.______________ It has also gained valuable experience for future projects in similar environments. A. The lessons learned from this project are very valuable. B. It was completed in 2006 after years of hard work. C. Pipes were used to keep the ground from melting. D. These bridges were built high enough to allow animals to pass under. E. The railway was built across the frozen ground of the Qinghai-Tibet Plateau. F. So they had to find other ways to solve the problem. 七、阅读理解 Creative Ideas Solve Difficult Problems The Qinghai–Xizang Railway is a great example of how creative ideas can solve difficult problems. It was completed in 2006 and is the highest railway in the world, reaching over 5,000 metres above sea level. One of the biggest challenges was the frozen ground. In summer, the top layer of frozen ground would melt and become soft. This made it impossible to build the railway directly on the ground. To solve this problem, engineers used pipes to keep the ground hard. The pipes were placed under the ground and helped maintain a low temperature. In some areas, the frozen ground was too soft even with the pipes. So engineers decided to build tunnels through the mountains instead of building on the ground. In other places, they built bridges over the soft ground. These bridges were designed to be animal-friendly so that wild animals could pass under them safely. Today, the railway is not only a transportation route but also a symbol of human creativity and determination. It has brought economic development and tourism to the region, and it continues to inspire people around the world. 1. When was the Qinghai–Xizang Railway completed? A. In 1901. B. In 1920. C.

It was completed in 2006 after years of hard work. The railway crosses frozen ground, mountains, and high-altitude areas where the air is thin and temperatures are extremely low. To build the railway, engineers used many creative methods. Pipes were placed under the ground to keep it frozen and hard. In some areas, tunnels were built through mountains. In others, bridges were constructed over the soft ground. The bridges were designed to be animal-friendly so that wild animals could pass freely. Today, the railway has brought many benefits. It has made travel easier and faster. It has also increased tourism and helped the local economy grow. The experience gained from this project is now being used to help build railways in other parts of the world. 1. When was the Qinghai–Xizang Railway completed?   2.
