So again, we should be able to check all of our formal charges and make sure they add up to 0, which they do, and that makes sense, because we have a neutral atom in terms of thionyl chloride.

因此同样地，我们可以检验一下,我们所有的形式电荷是否正确,确保它们加起来等于零，而它们确实是这样，这是合理的，因为亚硫酰氯是一个中性原子。

All right? And if you want to do other things, whoops, sorry-- and add them together, we will get out, again, a concatenation of that string. And these will, we'll let you work through the variations, but these are the simple expressions we can use.

对不对？如果你想要进行一些别的操作，哦，对不起-是加到一块，然后结果值也是，两个字符串的链接，这些会，我们会让大家慢慢学习变量，但是这些是我们能用的最简单的表达式。

那个程序很有趣,它有一个用Scratch做出来的清单,还有一个貌似容器的列表,你可以不断往里面加东西。
