Dick Morris suggested that before I made a formal announcement, I should go on television to acknowledge the mistakes and ask for another chance.

迪克·莫里斯建议，在正式宣布参加竞选之前，我首先要在电视上承认错误，请求再给我一次机会。

I don't actually go through the formal checklist, most of the time.

大部分时间，我实际上并没有详细研究正式的检查清单。

So, these are the different ways that we can actually go ahead and use formal charge when we're choosing between different types of Lewis structures.

那么，这些就是在我们需要在,不同的路易斯结构之间做选择的时候,我们如何用形式电荷来进行判断的各种方法。

And then we can go ahead and let's quickly write out w hat the formal charges for all of these will be.

然后我们可以开始很快地,把所有的形式电荷都写出来。

It's always a good first approximation, because you need to start somewhere in terms of drawing Lewis structures, but then if you go and figure out the formal charge and you just have lots of charge separation or very high charges, like a plus 2 and a minus 2 and a minus 1 all different places in the atom, what it should tell you is maybe there's a better structure.

它总是一个好的第一近似，因为在画路易斯结构的时候,你总需要一个起点，但是如果你在算出形式电荷之后,发现有很多电荷分开了,或者说有很高的电荷，比如有一个正二，一个负二，还有一个负一1,在原子的各个地方，这应该就是在告诉你,或许还有一个更好的路易斯结构。

Plus, out of the bag, the OM-D EM-5 is small enough to go to formal events, and weatherproof enough for anything from a hurricane to boating in the Mediterranean, without my worrying about a splash or two.

FORBES: Connect

The EU still thinks Turkey has further to go before formal accession negotiations can start, but even those member states least friendly to the Turks have been making conciliatory noises: on October 10th, the foreign minister of Greece, Turkey's traditional adversary, said he saw no reason why the EU should not set a date for accession talks with Turkey at its December summit in Copenhagen.
