1 . Standing at the top of the world, I cleared the ice from my oxygen mask（氧气面罩）， bent a shoulder forward against the wind, and stared absently down at the land of Tibet. Finally I had made it-the top of Mount Qomolangma.
I understood on some dim level（隐约地）that the earth down there was a grand sight. I’d been longing for this moment, and the excitement that would come with it. But now that I was finally here, actually standing on the top of Mount Qomolangma, I just couldn’t collect the energy to care.
It was early on the afternoon of May 10, 1996. I hadn’t slept for fifty-seven hours. My stomach was upset because the only food I’d been able to force down over the past three days was a bowl of soup. To make things worse, weeks of violent coughing had made ordinary breathing a bitter process. At 29,028 feet above the sea level, there was so little oxygen reaching my brain that I couldn’t think better than a slow child. Right now I could not feel much of anything except cold and tired. After taking four quick photos, I turned and headed down. I’d spent less than five minutes on the roof of the world.
Looking down the route we had climbed, I noticed something that until that moment had escaped my attention. To the south, where the sky had been perfectly clear just an hour earlier, a blanket of clouds now hid the lesser mountains surrounding. Nothing I saw early that day suggested that a violent storm was approaching. To my oxygen-exhausted mind, the clouds coming up the grand valley of ice appeared no different from the harmless clouds that rose from the valley almost every afternoon.
As I was climbing down, I began to get extremely anxious. However, my concern at that moment had little to do with the weather; I had almost run out of oxygen. I ought to have checked earlier. I needed to get down, fast.
