BBC 英语学习 新闻词汇 墨西哥的“水下王国”

Through the darkness and into an underwater kingdom.

Here, scientists hope to find clues which could unravel prehistoric mysteries.

And they did. The divers discovered a perfectly preserved cave with evidence of mining from 11000

years ago. What's really remarkable about the sites is the preservation.

This is incredibly rare in archaeology to find mind evidence for human activity that's this old and this well preserved.

They found ancient tools, evidence of fire pits and signs of excavation of Ochre, the vibrant red clay often used for rituals and artwork by the 1st people to inhabit the Americas.

The many hours spent on this underwater exhibition has shown a light on the ancient tribes, but exactly why they spent their time deep within the cave remains a mystery.
