Let's hear more from Dr Jamie Tehrani, anthropologist at Durham University in the UK.

让我们听英国杜伦大学人类学家杰米·德黑兰尼博士做关于这方面的更多介绍。

Imagine her as a confused child, tiptoeing that dark minefield of a mid-century Tehrani household, slapped for uttering a mysterious new word.

想象一下，她还是个懵懂的孩子，踮着脚尖行走在本世纪中叶德黑兰一户人家的黑暗雷区，因说出一个神秘的新词而被扇耳光。

But Sophie – if there's no written evidence of the stories from 6,000 years ago how does Dr Tehrani, who we've just heard from, know people were telling them?

但是，索菲，如果没有6000年前没有这些故事存在的文字证据，那刚才讲话的德黑兰尼博士是如何知道这些故事当时在人们之间流传的呢？
