透彻的研究你的纪录片主题。在开始拍摄以前，你得知道你到底要拍一个什么样的故事。就像故事片一样，纪录片中一样要有有趣的人物，冲突和故事情节。和故事片不同的是，所有这些都是自然而然的发生的，而不是在你的导演之下。

As with dramatic films, there needs to be interesting characters, conflicts and plots. Unlike dramatic films, these should occur naturally, without directing the people in your documentary.

It is to commit ourselves to what rational people (like us!) think an absurdity, an impossibility.

明显地，要知道什么时候X和Y是一样的人，我们就需要了解X在何时和Y有着同样的想法。

Clearly, to know when X is the same person as y, we would need to know when X has the "same soul" as y?

Last time we taught this class, we did a survey to find out what type of people were sitting in this room-- they are just like yourselves-- and find out why you'll be taking this class.

上一次我们教这门课时，我们做了一个调查，看看坐在这上课的都是什么类型的人-,他们就像你们一样-,看看为什么你们会上这门课。
