The mountain was high and it was cold. Everything (cover) by snow and ice and it was dangerous. I shook in my tent as the storm tried (knock) me back to the bottom. ""You will never make it to the top, "everyone said, "no woman has climbed this mountain and only a few people have done it by themselves. "I was so confident I would be the first woman to climb up to the top of Whitmore. I had prepared for several (month).
The wind had gotten much (quiet) when I woke up the next morning. I climbed out of my tent and looked out at the mountain. Everything was white and still. "I will make it to the top today, "I thought to (I).
I started up the slope. My feet crunched the snow with every step I took. It was a beautiful day. I was climbing quickly. Soon I was going to reach the top. All of sudden, I slipped (滑倒). I moved down the mountain. I was going slowly at but then I started to slide very fast. I started to turn around and around quickly. After what felt forever, I came to a stop. I had slid all the way to the bottom. I was alive. I couldn't believe it.
Three days later, I made it to the top. It was a beautiful day and I had a perfect view of everything around me.

2022年北京冬奥会,中国交出了办赛和防疫双重完美答卷,受到了国际社会的盛赞。下面是一位冬奥志愿者的自述历程(摘录):
当北京2022年冬奥会志愿者招募消息传来,我第一时间报了名。经过层层筛选、多次面试,2021年11月底,我正式收到北京冬奥组委志愿者岗位录用通知,并进行了系统的学习和培训。在冬奥志愿者誓师大会上,我发出了自愿参加北京2022年冬奥会和冬残奥会志愿服务的誓言。在冬奥会召开的日子里,时常凌晨4点半披星而去,深夜12点戴月而归。这样的日子尽管又苦又累,但每次出任务时我们都彼此加油,完成任务后分享快乐。签名墙上运动员留下的签名与赞美、国际官员留下的“Bestteam!”等等,都是对我们志愿者工作的认可与鼓励,更是对中国的赞扬与尊重。
