It does not mean we should not make them, it does not mean that there are not younger and more reformist elements or pragmatic elements in most of these regimes that we can engage."

Now I think in order to make this viewpoint seem plausible, we probably should study it for a moment a little bit more philosophically.

现在为了让这个观点听起来更合理一些，我们可能,应该更哲学地学习一下。

And it should make sense where we got this from, because we know that the binding energy, if we're talking about a hydrogen atom, what is the binding energy equal to?

很容易理解，我们怎么得到这个的，因为我们知道，结合能，如果，对氢原子来说，结合能等于什么？

But why? What is it about the facts about life and death that seem to make it misguided to think ? we should just put them aside and pay no attention to them?

但是为什么？，关于生和死的什么事实,似乎让我们误以为,我们应该把它们撇到一边，置之不理？

if you don't want to use that, you can also derive it as we did every time, it should intuitively make sense how we got there. But the exams are pretty short, so we don't want you doing that every time, so we'll save the 2 minutes and give you the equations directly, but it's still important to know how to use them.

吸收的和发射的，如果你不想用公式,你也可以每次都向我们这样推导它,很直观的就能得到结果，但考试时间很短，我们不希望你们每次都推导,所以我们会直告诉你，让你节省2分钟，但知道如何应用它十分重要。

This should make a lot of sense, because we know that a hydrogen has 1 s as it's outer-most or valence orbital, so it can be filled up just with two 1 s electrons.

这也是很合理的，因为我们,知道氢只有，1，s，轨道,这就是它最外层的轨道或者说价轨道，因此只要两个，1，s，电子就可以将它填满。

So it already should make sense why we have that p orbital there, in order to form a pi bond, we're going to need a p orbital.

这里有p轨道是很合理的,为什么我们在这里有P轨道，为了形成一个π键，我们需要一个p轨道。
