We don't know the intended recipient of this letter, and we actually have no idea whether Milton actually sent the letter; but a couple of drafts of this letter actually exist in Milton's own hand, and the letter is clearly a document that Milton had devoted some energy and some time to. We need to look at it.

So the instinct of many cabinet officers and other senior officials is "Boy, when we take this to the president, let's see if we can reach some sort of 4 compromise, you know, you say 2, I say 4, let's just go tell the president 3 that we've agreed on 3."
所以许多内阁官员,还有其他高层的领导人的本能都是，我们把这个给总统处理之前，先看看我们能不能各自让步,比如你说2，我说，我们就告诉总统,我们都同意“

So let's see, we started with 8 bonding electrons, and we used up only 4, so the answer is yes, we have 4 bonding electrons left.
那么让我们来看看，我们一开始有八个成键电子，然后只用掉了四个，因此答案应该是还有剩余，我们还剩下了四个成键电子。

Again, to show you the difference, a different perspective, from a different point of view about the impact of this diet you can look at something like that.
我们再从另一个视角,来看看这种饮食结构的影响,你们可以看看这些对比
-
So, this means we have the general trends down, so we should be able to look at actual atoms in our periodic table and graph them and see that they match up with our trends.
那么，这表示我们已经知道了大体的规律，现在我们可以来看看周期表中的,原子的实际情况，并把它们画出来,看看是否与我们的规律相符。
