○  Ted英语演讲稿：On what we think we know？我们以为自己知道的  ○

　　I'm going to try and explain why it is that perhaps we don't understand as much as we think we do. I'd like to begin with four questions. This is not some sort of cultural thing for the time of year. That's an in-joke, by the way.

　　我会试着解释为何 我们知道的东西很可能并没有我们自以为知道的多 我想从四个问题开始,不是那种今年流行的文化问题 对了，刚刚那句是个圈内笑话

　　But these four questions, actually, are ones that people who even know quite a lot about science find quite hard. And they're questions that I've asked of science television producers, of audiences of science educators -- so that's science teachers -- and also of seven-year-olds, and I find that the seven-year-olds do marginally better than the other audiences, which is somewhat surprising.

　　不过这四个问题，事实上 即使是很懂科学的人也会觉得很难应答 我拿这些问题去问科学节目制片人 问那些有科学教育背景的观众 也问教科学的老师还有七岁孩童 我发现七岁孩童答得比其他人好 这是有些令人惊讶

　　(敲椅声)

　　And your next question is, can you light a little torch-bulb with a battery, a bulb and one piece of wire? And would you be able to, kind of, draw a -- you don't have to draw the diagram, but would you be able to draw the diagram, if you had to do it? Or would you just say, that's actually not possible?

　　问题二，你能否点亮一个小灯泡 只用1个电池、1个灯泡、和1条电线? 那你能画出上述问题的图解吗?不用真的画 但如果需要的话， 你能画出来吗? 还是你会说 这个不可能?

　　The third question is, why is it hotter in summer than in winter? I think we can probably agree that it is hotter in summer than in winter, b
