I've been in a few disused mines as a tourist, not as a Paul Kudinaris-level spelunker, but you hear all sorts of noises.

作为一名游客， 我曾探访过几处废弃的矿，达到保罗·库迪纳里斯那样的洞穴探险水平，但各种声响不绝于耳。

For this group of seasoned spelunkers, it should be a fun day out, an opportunity to do what they love, unencumbered by the demands of scientific fieldwork.

对于这群经丰富的洞穴探险者来说，这将是一个轻松愉快的日子， 一个做他们热爱之事的，需受科学实地考察任务的束缚。

He was a spelunker, somebody who goes and explores caves on the side, just this wild animal of a human being that I wish I could have met.

他是一名洞穴探险家， 一个业余探索洞穴的人，就像一头充满野性的动物， 真希望我能见到他。
