"We don't want to come here two years later, three years later,or four year later to again talk about the extremism,terrorism, drugs,and so on and so forth,".
VOA: standard.2009.03.27

Clearly, Milton is in some way wonderfully speaking through the Lady here. Then we get the Lady again: Shall I go on?Or have I said enough?
确实，弥尔顿在一些方面【笑】,让这位女士替他说话，让我们继续看这位女士：,我应该继续吗？还是我说的够多了？
-
So here we have a second definition, a new definition for today, and again we can use our jargon.
这里我们给出第二个定义,也是今天的一个新定义,我们再一次用到术语
-
For any one of those, we could again run an argument where we say, "Look, here is something that needs explaining.
对于以上任意一个,我们都能再次提出一个论证,看啊,这里有某个东西需要解释
-
All right? And I'm going to say-- sort of set that stage here, so that-- It turns out that that's probably about the best we can do, or again ends at the length of the list.
我要说的是，这一阶段的集合,我们用最优的方法完成,还是取决于列表的长度，好的，还是回到了我的问题上了。
-
So again, we can fill in our atomic orbitals here, there's going to be two electrons in each of our atomic orbitals.
同样的，我们可以填充原子轨道，每个原子轨道上有两个电子。
-
- So again, if you're unwinding what's going on here, this-- we sorted the left half which meant sort the left half, then the right half then the merge.
同样，如果你展开正在进行的一切-,我们已对左半部分排好了序，接着右半部分，接着合并。
-
And so, if we go and we draw this again, if this is the carbon here, hydrogen, hydrogen, hydrogen, hydrogen like this, then this is going to be a little bit plus.
如果我们继续，我们将再次画下这个，如果这儿是碳，氢，氢，氢，氢，就像这样，这里有些正电荷。
-
Okay. Let's sing it again. Here we go. Ready, go.
好了,大家一起唱,准备,开始
-
Let me try it again, here we go .
我再试试,好了
-
Here again, we'll look at some paintings.
在这里,我们会看一些画作
-
Well, what we can see here is that I'm computing the same value over and over again.
好吧，我们现在看到的是,我不断地在计算同一个值。
-
Again, easy pass here just means no mountains, we're not talking about something on the New Jersey Turnpike.
强调一下 平坦之途不用翻山越岭,我们说的不是新泽西收费公路
-
So again, what we're saying here is that it is most likely in the 3 s orbital that we would find the electron 11 and 1/2 times further away from the nucleus than we would in a around state hydrogen atom.
同样我们,这里说的是,氢原子３ｓ轨道中,最可能找到电子的地方,是基态的１１．５倍。
-
We've got Lynette, Lukucin, we've Kristin, Bargeon; there's nine of you here. Let's try it again.
利奈特,鲁克森,克里丝汀,博贞,有九个人,再举下手示意一下
-
But here we're going to add 1, so again, we have 10 valence electrons.
但是这里我们要加上一个，那么跟刚才一样，我们有十个价电子。
-
Let's go the other direction. And yes, I guess I'd better say s not 2, or we're going to get an error here. Again, in twenty-three checks.
这里我得说不能是2，否则要报错了，再一次，调用了23次,在这个例子里，它从尾部开始。
-
putting all those things together, if you looked at this question again we'd get 100% on it, 0 9 that our only option here is 0. 9, and that it's not the negative, it's the positive version, because we're talking about how much energy we have to put into the system in order to eject an electron.
把这些放在一起，你们再看一下题目,大家100%都能选对，我们唯一的选择就是这个，它不是负数，它是正的，因为我们说的，是要,把电子激发出来,需要提供的能量。
-
And again, we need to be a little bit careful here.
这会我们稍微严谨一点
-
And the thing you should notice here is that it's doing a lot of the same things over 2 1 and over again. So, for example, we'll see 2, 1 2 1 here. And 2, 1 here.
在这里你要注意的是,它不断在重复同样的工作,例如我们看这里的1,还有这里的。
-
Now the modulation--change of key from major to back to minor as the cortege will start up again and then we-- A nice clarinet sound there and here comes our cortege with the bass.
现在变调了,从大调,变回小调,送葬行列再次启动,然后我们听到了优美的单簧管,送葬行列伴随着低音来了
-
What's happening and interests me acoustically, and again we'll come back to it, is that we're getting up toward here, and notice how these pitches in terms of the ratio frequencies are getting very close together.
这段乐曲从声学的角度上让我很感兴趣,我们再看看它,音乐升高到这里,然后我们注意到这些音高,是如何根据频率比最后汇合在一起的
-
Here we might then have an entire other family of arguments, set of arguments--again, still of the form "Inference to the best explanation."
这里我们就有了全新的一类论证,一系列的论证,但仍需遵循,"最佳解释推理"
-
All we're going to do here is really just, once again, scratch the surface.
我们在这里只是，肤浅地解析一下。
-
And when we talk about size, I'm again just going to say the stipulation we're not talking about an absolute classical concept here, but in general we're going to picture it being much further away from the nucleus as we move up in terms of n.
当我们说到尺寸时，我们只是说――,经典的绝对的概念，而是它大约,离原子核有多远。
-
it's an easy calculation -- we're just taking the negative of the binding energy, again that makes sense, because it's this difference in energy here. So what we get is that the binding energy, when it's negative, the ionization energy is 5 . 4 5 times 10 to the negative 19 joules.
这个计算很简单-我们,只需要取结合能的负值,同样这很容易理解，因为这就是这的能量差,所以我们得到的就是结合能,当它取负值，电离能就是5。45乘以。
-
But actually there is a little bit of an energy cost into doubling up into a single orbital, because, of course, it takes energy when you create more electron repulsion, that's not something we want to do, but we have to do it here, and it turns out that that effect predominates over, again, the energy that we gain by increasing the atomic number by one.
但实际上，在一个轨道上放两个电子,确实会亏损一点能量，因为，当你加入更多电子，引起更大的排斥能,这显然会消耗能量，这不是我们想要做的，但是在这种情况下我们不得不做，结果这一影响，超过了增加一个,原子序数所得到的能量。
-
We'll get to discussing that, but what I want to point out here again is the fact that instead of just being dependent on n, the energy level is dependent on both n and l.
我们将要讨论它，但是我想指出的是事实上能级不只是与n有关,而是与n和l都有关系，而且n不再是。
-
And so if we wanted to do this here, it's again, the same thing we're just now pulling back this layer and calling them char *s not actually strings.
如果我们想要在这里这样做，再次，我们撤销这一层,把它们叫做char，*s，实际上不是字符串。
-
All right, so if we think about b h bond here, again, it's the sigma bond, and we're going to say it's a boron 2 s p 2 hybrid orbital interacting with a hydrogen 1 s orbital.
这可以告诉我们，为什么它倾向于周围只有6个电子，好了，考虑一下这里的BH键,同样的，它是sigma键,我们说。
