A kind of addition approach to values of wholes may not always be correct.

一种把所有价值加起来的方法不一定一直正确。

But I want to pause for a moment and note that this assumption that the way to think about the value of the combination as just a matter of adding the goodness of life and the badness of death and just summing them that way-- that may not be right.

但我想暂停一会并指出,这个用加上生命的好处,和死亡那个的坏处然后求和的方式,去考虑这个组合的价值的假设-,可能并不是正确的。

So that means that we don't have to worry about things like wave functions when we're talking about Lewis structures, but because they're so simple to use and because they so often predict the electron configuration of molecules accurately, we end up using them all the time in chemistry, so it's very valuable to know how to draw them correctly and to know how to work with them.

因此这也就意味着我们在讨论路易斯结构的时候,不需要担心波函数之类的东西，但是由于路易斯结构不仅简单易用,而且用它来预测分子的电子排布,经常可以得到非常精确的结果，结果我们在化学中一直都在用它，因此知道如何正确地画出并运用,路易斯结构是非常有价值的。
