That is, until the great archaeological discoveries of the nineteenth and twentieth centuries, which unearthed for us the great civilizations of the Ancient Near East, of which I have drawn a remarkably life-like map ] here on the board: Mediterranean, I always start with the Mediterranean Ocean, the Nile River, the Tigris and the Euphrates.

直到十九至二十世纪,一些重大的考古发现，才让我们了解到,远古近东的文明,我已经在黑板上画了一幅,栩栩如生的地图了：,地中海，我总是从地中海讲起，尼罗河，底格里斯河，还有幼发拉底河。

It's always a good first approximation, because you need to start somewhere in terms of drawing Lewis structures, but then if you go and figure out the formal charge and you just have lots of charge separation or very high charges, like a plus 2 and a minus 2 and a minus 1 all different places in the atom, what it should tell you is maybe there's a better structure.

它总是一个好的第一近似，因为在画路易斯结构的时候,你总需要一个起点，但是如果你在算出形式电荷之后,发现有很多电荷分开了,或者说有很高的电荷，比如有一个正二，一个负二，还有一个负一1,在原子的各个地方，这应该就是在告诉你,或许还有一个更好的路易斯结构。

We don't always want to go and solve the Schrodinger equation, and in fact, once we start talking about molecules, I can imagine none of you, as much as you love math or physics, want to be trying to solve this Schrodinger equation in that case either. So, what Lewis structures allow us to do is over 90% of the time be correct in terms of figuring out what the electron configuration is.

我们并不想每次都去解薛定谔方程，而且实际上，一旦我们开始讨论分子，我可以想象,你们中没有一个人，不管你有多么热爱数学或物理，会想去解这种情况下的薛定谔方程,总之，路易斯结构能让我们,有超过，90%，的概率判断出正确的,电子排布。
