Once you're doing this on your own, -- especially, for example, on exam 2, which is a ways down the road, you won't be able to look at those steps, so you need to make sure that you can go through them without looking at them, but for now we can look at them as we are actually learning how to draw the Lewis structures, and rather just go through them step-by-step, it's more interesting to do it with an example.

每当你要画一个路易斯结构的时候，特别是，比如，在第二次考试中，在不远的将来，你将看不到这张表，因此你需要确保自己在不看这张表,的情况下也能按照上面的流程来画，但是目前我们是可以看着这张表,来学习如何画路易斯结构的，而相比于一步一步地讲，通过例子来演示一下会更有意思。

I can write it explicitly. I can write it inside of a FOR loop. And we've started to add, and we'll see a lot more of this, examples of collections of structures so that we don't just have to do something that can be easily described as walking through a set of things but can actually be a collection that you walk through.

我可以明确的写出来,我可以把它在FOR循环的内部写出来，然后我们开始学习了add这个运算符,我们会在以后学习很多的,集合的数据结构的例子,这样一来我们可以进行一些,很简单的遍历集合的操作,我想要为大家指出的最后一件事情是。
