TED演讲-中英对照-英语笔记-Why TED talks are better than the last speech you sat through

他们认真思考他们真正想说的话,”他对加洛说。此外,安德森说,如果你希望你的讯息像病毒般扩散,这也是一个完美的时间长度。

Recent neuroscience shows why the time limit works so well: People listening to a presentation are storing data for retrieval in the future, and too much information leads to "cognitive overload," which gives rise to elevated levels of anxiety -- meaning that, if you go on and on, your audience will start to resist you. Even worse, they won't recall a single point you were trying to make.

最近的神经科学研究说明了为什么这项时间限制产生如此好的效果:聆听陈述的人们往往会存储相关数据,以备未来检索之用,而太多的信息会导致“认知超负荷”,进而推升听众的焦虑度。它意味着,如果你说个没完没了,听众就会开始抗拒你。更糟糕的是,他们不会记得你努力希望传递的信息点,甚至可能一个都记不住。

"Albert Einstein once said, 'If you can't explain it simply, you don't understand it well enough,'" Gallo writes, adding that the physicist would have applauded astronomer David Christian who, at TED in 2011, narrated the complete history of the universe -- and Earth's place in it -- in 17 minutes and 40 seconds. “爱因斯坦曾经说过,‘要是你不能言简意赅地解释某种理论,那就说明你自己都还没有理解透彻,’”加罗写道。他还举例说,物理学家或许会大加赞赏天文学家大卫•克里斯蒂安在2011年TED大会上发表的演讲。克里斯蒂安在这个演讲中完整地讲述了宇宙史及地球在宇宙的地位,整场演讲用时只有17分40秒。

Gallo offers some tips on how to boil a complex presentation down to 18 minutes or so, including what he calls the "rule of three," or condensing a plethora of ideas into three main points, as many top TED talkers do. He also notes that, even if a speech just can't be squeezed down that far, the effort alone is bound to improve it: "Your presentation will be far more creative and impactful simply by going through the exercise."

如何把一个复杂的陈述压缩至18分钟左右?加洛就这个问题提供了一些小建议,其中包括他所称的“三的法则”。具体说就是,把大量观点高度浓缩为三大要点。TED大会上的许多演讲高手就是这样做的。他还指出,即使一篇演讲无法提炼到这样的程度,单是这番努力也一定能改善演讲的效果:“仅仅通过这番提炼,你就可以大大增强陈述的创造性和影响力。”

Then there's PowerPoint. "TED represents the end of PowerPoint as we know it," writes Gallo. He hastens to add that there's nothing wrong with PowerPoint as a tool, but that most speakers unwittingly make it work against them by cluttering up their slides with way too many words (40, on average) and numbers.

另一个建议与PPT文档有关。“TED大会象征着我们所知的PPT文档正走向终结,”加洛写道。他随后又马上补充说,作为工具的PowerPoint本身并没有什么错,但大多数演讲者
