Somebody's up there going and it's actually the bass so we'll be wanting to zero in on the bass in a big way in music because that's oftentimes giving us much more information than the melody.

有些人在那唱,事实上那是低音,所以我们在音乐中,主要将注意力集中到低音上,因为大多数情况下,相比旋律而言,低音给我们的信息更多

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。

So what we are doing: we cultivate the positive; we are strengthening our,metaphorically speaking, " psychological "engine"; and we are better able to deal with the negative to zero, not to mention the fact that we are also able to become happier.

所以我们在做的是，培养积极性;,按那个比喻来说，我们正在增强，心理“引擎;,我们能够更好将负值转化为零，更别说还能变得更快乐。
