1 . Journey Back in Time with Scholars

2 . When I was 17, I read a magazine article about a museum called the McNay, once the home of a watercolorist named Marian McNay. She had requested the community to turn it into a museum upon her death. On a sunny Saturday, Sally and I drove over to the museum. She asked, "Do you have the address? ""No, but I'll recognize it, there was a picture in the magazine. "

"Oh, stop. There it is!”

The museum was free. We entered, excited. A group of people sitting in the hall stopped talking and stared at us.

"May I help you?" a man asked. "No, "I said. "We're fine.” Tour guides got on my nerves. What if they talked a long time about a painting you weren't that interested in? Sally had gone upstairs. The people in the hall seemed very nosy(爱窥探的), keeping their eyes on me with curiosity. What was their problem? I saw some nice sculptures in one room. Suddenly I sensed a man standing behind me. "Where do you think you are? " he asked. I turned sharply. "The McNay Art Museum!" He smiled, shaking his head. "Sorry, the McNay is on New Braunfels Street." "What’s this place?” I asked, still confused. "Well, it's our home." My heart jolted(震颤). I raced to the staircase and called out, "Sally! Come down immediately! "

"There's some really good stuff(艺术作品) up there." She stepped down, looking confused. I pushed her toward the front door, waving at the family, saying, "Sorry, please forgive us, you have a really nice place." Outside, when I told Sally what happened, she covered her mouth, laughing. She couldn't believe how long they let us look around without saying anything.

The real McNay was splendid, but we felt nervous the whole time we were there. Van Gogh, Picasso. This time, we stayed together, in case anything else unusual happened.

Thirty years later, a woman approached me in a public place. "Excuse me, did you ever enter a residence, long ago, thinking it was the McNay Museum?"

"Yes. But how do you know? We never told anyone."

"That was my home. I was a teenager sitting in the hall. Before you came over, I never realized what a beautiful place I lived in. I never felt lucky before. You thought it was a museum. My feelings about my home changed after that. I've always wanted to thank you."

4 . Many families take their children on vacation. They will usually travel for a few days or weeks during school breaks. But Mr and Mrs Smith have planned a longer vacation with their two children. The Smith family is on a one-year trip around the world, and they planned to visit 30 countries in all. Right now, the four travelers are about halfway through their trip.

Mrs Smith says they are trying to see as much of the world as they can. Mr Smith says one of the most interesting experiences of the trip has been meeting new people. He says people have been extremely friendly, very welcoming and love their kids. Eleven-year-old Tyler says he has enjoyed learning about the people they have met. He says, “I learned in Africa that people have very different lifestyles.” His sister, Kara discovers that she likes Thai food. Mrs Smith says that the trip teaches the children a lot.

The Smiths made good preparations for the trip. They did a lot of research, choosing destinations and arranging accommodations. Mr Smith uses unpaid leave. They carry small bags filled with lightweight clothing and whatever else they need. Mrs Smith says she enjoys being able to carry everything she needs on her back. “What has become important is making unforgettable memories as a family and taking ‘those’ with us instead.” The Smiths will continue to head east for the next six months.

8 . 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-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.

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 kilometers an hour.

To prevent damage to wetlands and grasslands, 675 bridges with a total length of about 160 kilometers were built between Golmud and Lhasa. We even moved 140,000 square meters 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 meters 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-kilometer 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”.
