探寻背景A：尤卡坦半岛位于墨西哥湾和加勒比海之间,为中美洲北部的半岛,它的北部,就像是一块低平的石灰岩平台,在200万年前从浅海区升高而形成。B：大约在一万年前的冰河世纪,地球的整个海平面都要比现在低100米,所以很多洞穴曾经都是干燥的,很多动物都会选择居住在这里,而之后水面上升将这些洞穴永远淹没。 Discovering the Background A: The Yucatan Peninsula, located between the Gulf of Mexico and the Caribbean Sea, is a peninsula in the northern part of Central America. Its northern part resembles a low-lying limestone platform that rose from the shallow sea two million years ago . B: About the ice age of 10,000 years ago, the entire sea level of the earth is 100 meters lower than it is now, so many caves were once dry and many animals would choose to live here, and then the rising water will leave these caves forever Submerged.
