In principle, we could play this with the whole class, but let's single out a particular row of the class so I'm going to come down here and I guess eventually, well I'll grab it in a minute.

理论上,我们可以全班一起做这个博弈,但我要选出特定的一行,我先走下来,我觉得,我很快就能挑到人

So, a part of you wants to become the greatest whatever it is that you want to become and you wouldn't be here if you weren't very competitive and very eager to come out first, devoted to arete and your own version of that kind of thing.

所以 你的一部分意识想变成最伟大的人,不论你想要在哪个领域变得伟大,而且如果你没有竞争力,或不是一直争取第一,那你也不会坐在这里,力图更上一层楼,以穷千里目

All right, we're-- well actually, I should say that better, we first check to see, is x 0 greater than or equal to zero, if it's not, then we come down here and we print something out, otherwise we run through a little loop to get the answer, and then we check it and we spit something out.

然后我们运行一个小循环,好了，我们现在来看看,如果x≥0或者x＜,我们看这儿,我们会输出一些内容,或者我们运行一个小循环来获取答案,然后我们检验一下，然后得到结果。

But notice what this does. The first thing it does is, it says, let's check and make sure x is greater than or equal to 0. If it isn't, notice what's going to happen. None of that block is going to get executed, and it's going to come down here and print out a useful piece of information, which says, hey, you gave me a negative number. I don't know how to do this.

做的是和以前一样的事情,但是注释它做了什么，第一件做的事情就是,程序说，要去检查并且确信x是大于等于0的，如果不是的话，请注意会发生什么,下面的代码都不会被执行,程序会到这里来然后显示一些有用的信息,信息会说，嘿，你给了我一个负数,我不知道该怎么弄这个了。
