2025年高中英语选修一外研版课文改编题 （阅读理解、完形填空、正确形式填空） Unit 6-1 The sky railway 一、阅读理解（共5题） 阅读下面短文，从每题所给的A、B、C、D四个选项中，选出最佳答案。 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". I was one of the people who came from all parts of China to work on this railway. Taking years to complete, the Qinghai-Xizang 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. 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. 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. 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. 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". 1. Why does the writer feel proud? A. He traveled on the world's fastest train. B. He helped build the "impossible" Qinghai-Xizang Railway. C. He saw many rare animals on the plateau. D. He visited the highest railway station in the world. 2. What was a top concern during the railway construction? A. Building long bridges over permafrost. B. Making enough oxygen for workers. C. Protecting the delicate ecosystem. D. Reducing construction waste. 3. What is special about Qingshuihe Bridge? A. It is the longest bridge in the world. B. It is built to protect Tibetan antelopes. C. It is the highest bridge on the plateau. D. It is the world's longest bridge over permafrost. 4. How did workers protect Cuona Lake? A. They moved the lake to a new area. B. They built a wall to stop construction waste. C. They planted grasslands around the lake. D. They set up stations to clean the lake water. 5. What can we infer about the Qinghai-Xizang Railway? A. It was built easily with foreign help. B. It has no negative effect on the environment. C. It connects people and protects nature. D. It is the only railway on the Qinghai-Tibet Plateau. 二、完形填空（共15题） 阅读下面短文，从每题所给的A、B、C、D四个选项中，选出可以填入空白处的最佳答案。 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 working hours are flexible and accommodation is provided. Key duties include exploring the islands of the reef and finding out what the area has to offer. You'll need to report back via weekly blogs, photo diaries and video updates. You'll also be asked to promote the islands through newspapers, magazines and TV interviews. It was actually a very clever means to highlight the importance of the Great Barrier Reef and the need to protect it. About the size of Japan, it even can be seen from outer space. More than 25 million years old, the Great Barrier Reef is made up of living coral growing on dead coral. It is host to many species of birds and sea creatures. But this unique and delicate place is now under threat from pollution and climate change. To get this job, the candidates had to make a short video showing how much they knew about the reef. They also needed to prove why they were the best person to do the job. Out of the thousands of applicants, eleven were selected, including a young woman from China. Eventually, the job was offered to Ben Southall from the UK. In addition to blogging, taking photos and writing articles about the reef, he made a number of appearances on television to argue in favour of its defence. He also worked as a presenter for the National Geographic Channel, before going on to write a book about his experiences. Ben later joked that the job should have been advertised not as the"best", but the"busiest job in the world"! The most important thing was that people all over the world became aware of the beauty of the ocean in the area. What's more, they came to understand the delicate balance that the environment exists in and what can, and must, be done to protect the reef. That way, it will remain a safe habitat for wildlife, as well as a dream destination for the millions of tourists who visit it each year. 1. What is the main purpose of the "island job" mentioned? A. To attract more tourists to the Great Barrier Reef. B. To highlight the reef's importance and call for protection. C. To find someone to live on the island and take photos. D. To promote the National Geographic Channel. 2. What threat is the Great Barrier Reef facing? A. Overcrowding from tourists. B. Lack of living coral. C. Pollution and climate change. D. Destruction by sea creatures. 3. What was required for candidates to get the job? A. To have lived on an island before. B. To make a video about their knowledge of the reef. C. To have written books about oceans. D. To be good at scuba diving. 4. What did Ben Southall NOT do in his job? A. Write weekly blogs about the reef. B. Host TV shows for a channel. C. Advertise the job as the "best" one. D. Write a book about his experiences. 5. What is the greatest value of Ben's job? A. It made him famous worldwide. B. It helped people realize the need to protect the reef. C. It brought more tourists to the reef. D. It proved the reef is larger than Japan. 二、完形填空（共15题） 阅读下面短文，从每题所给的A、B、C、D四个选项中，选出可以填入空白处的最佳答案。 How would you like to spend six months living on an island and looking after the Great Barrier Reef?
