So what I'm going to try to do in the next 17 and a half minutes is I'm going to talk first about the flames -- where we are in the economy -- and then I'm going to take three trends that have taken place at TED over the last 25 years and that will take place in this conference and I will try and bring them together.
所以在接下来的17.5分钟里，我着意要做的是 首先要谈一谈这火焰 目前我们所处的经济状况 接着我要提出三个趋势 这三个趋势已经在过去25年的TED大会上提到过 也会在这次的会议上涉及 并且我会尝试把它们联系到一起。
