We see three bonding pairs so this is a triple bond, indeed a multiple bond.

我们看到3对成键电子所以这是一个三重键，它确实是多重键。

Place the non-bonding pairs on peripheral atoms first, which the higher average valence electron energy.

首先将孤对电子放在外围的原子，那儿具有较高的平均价电子能。

Now if you read in the book, you read about where this figure is shown in the book, you can understand more about why these structures line up in the right way so that the right molecular elements are together to form hydrogen bonding pairs between them.

如果你预习过课本,课本中有关于这些详细的描述,你可以更深刻的理解,为什么这些结构是采用这种连接方式,以使对应的分子部分靠近,并形成氢键连接

So since we have two lone pairs, we're going to be pushing down even further on the bonding electrons, so we're going to smoosh those bonds even closer together.

因为我们有了两个孤对，我们会把成键电子,更加向下压，所以我们把这些键更加紧得推到一起。
