我有一种想法，就是对我们来说，世界是一个我们所站立的平坦的东西，而对鸟来说是一个它们所依靠的峭壁。

I have this theory that, to us the world is a flat thing we stand on, but to birds it is a cliff they cling to.

现在我对演讲更加自信了，下面是我从自己的经历中总结出来的一些想法。

I now feel a lot more confident about speaking, so here are some ideas that I have taken from my own experience.

So I think I can safely say that most people had the right idea and were counting quickly, 3 though I have a feeling that some people who wrote 13 might have forgotten about those 4 f, the 4 f electrons.

我认为我可以放心地说,大部分人的想法都是对的,数得也很快，只是我感觉不少选，13，的人都是因为3,忘了，4，f，4，f，电子。
