So I thought long and hard, and I stood here two days ago, and I had my test run, and I had my cards and my clicker in my hands and my pictures were on the screen, and I had my three lessons, and I started presenting them, and I had this very odd out-of-body experience.
（鼓掌声） 我努力想了很久， 然后我两天前站在这里， 测试运行了下，确保准备好了提示卡， 手中的遥控器没问题，照片显示在屏幕上， 也准备好了三点经验教训，我开始演讲， 我有了这次神奇的超乎想象的经历。
