So we haven't come across Tunguska yet.

所以我们还没有看到通古斯卡。

So I see the Tunguska River and air bursts the size of Tunguska.

所以我看到了通古斯卡河还有空气爆炸的尺寸跟通古斯卡一样。

So we have Chelyabinsk and Tunguska meteor strikes to scan for.

所以我们要寻找车里雅宾斯克和通古斯卡陨石撞击。

Now we're going to be scanning for Tunguska.

现在我们要搜索通古斯卡的信息。

For the last hundred years, the Tunguska explosion has been shrouded in controversy.

在过去一百年里，通古斯加爆炸一直笼罩在争论之中。

And so I'm just going to scan until I see Tunguska.

所以我要浏览直到我看到通古斯卡。

So by scanning for Chelyabinsk and also Tunguska, really led us in the right direction.

因此通过浏览寻找车里雅宾斯克和通古斯卡将我们引上了正确的方向。

Alright, let's move to the right hand side, the Tunguska meteor strike.

好的，我们移到右边，通古斯卡陨石撞击。

Okay, so this obviously is not a very plausible explanation for the Tunguska event.

安妮：好的，这显然不是通古斯事件的一个非常合理的解释。

So there are two different columns for this table: The Chelyabinsk meteor strike and the Tunguska meteor strike.

车里雅宾斯克陨石撞击和通古斯卡陨石撞击。

Tunguska Event Speaking of Stalin, let’s go back to Russia in 1908 when a 12-megaton explosion  occurred near the Podkamennaya Tunguska River.

通古斯事件说起斯大林，让我们回到 1908 年的俄罗斯，当时在 Podkamennaya Tunguska 河附近发生了 12 兆吨级的爆炸。

The largest meteor known to have actually hit the earth during our recorded history was probably the Tunguska event which happened back in 1908.

历史有记录以来，已知的撞击地球最大的流星，很可能是 1908 年发生的通古斯大爆炸事件。

Tunguska just gives you kind of like a case study for, like, okay, well is it possible that it could have been?

通古斯卡只是给你提供了一个案例研究，好吧，有可能是这样吗？

And then for Tunguska, we had to move all the way down to the end of the passage, which again is rare for table completion.

然后对于通古斯卡，我们得向下移动到文章结尾，这对于表格填空题型来说很罕见。

Alright, so the fact that we are under Tunguska in this column here is an excellent clue that the diameter under Tunguska in the passage is 36.5 and that is our answer for number four.

好的，因为我们在通古斯卡这一栏下面，所以这是一个很好的线索，文章中通古斯卡下面的直径是36.5，而这就是我们第四题的答案。

But, you know, it's pretty plausibly an atmospheric explosion, and I think, you know, most scientists have sort of dusted their hands off and moved on to the next question with regards to Tunguska.

但是，你知道，这很可能是一次大气爆炸，而且我认为，你知道，大多数科学家已经放下手上的灰尘，转向下一个有关通古斯的问题。
