雅思阅读真题+题目+答案：An Insanely Dangerous Activity

雅思阅读真题原文如下：

Agnes Milowka was one of the foremost cave divers in the world. Female, photogenic, and experienced, she had gained international recognition for her exploratory work in many underground caverns around the world. In early 2011, she entered Tank Cave, near Mount Gambier, a seven-kilometre maze of narrow tunnels – yet ones she had explored many times before. Deep inside, she parted company from her dive buddy to explore a tight passageway through which only one person could pass. What happened next will never be exactly known, but the nature of the cave suggests that she became disoriented during a ‘silt-out’. Unable to manoeuvre quickly, with visibility almost zero, she could not find her way back, and her air ran out.

Thinking of these last moments is disturbing, but illustrates the obvious dangers of cave diving. When anything goes wrong, divers cannot swim vertically to the surface, but must instead navigate the entire way back. The dive is immediately abandoned, but even with the full team at hand, the return is complicated by narrow tunnels, often lined with sand, mud, or clay, all of which can be easily disturbed – the dreaded ‘silt-out’ – where, in a few seconds, the diver is in a panic-inducing soup of sediment, virtually blind. Artificial light is swallowed in the pitch blackness, and there always needs to be sufficient breathing gas. In short, cave diving seems an insanely dangerous activity.

Yet the cave-diving community disputes this, arguing that their sport is actually safer than normal open-sea recreational diving. This is due to the much greater degrees of experience and training, and the special equipment used. Most fatalities that have occurred are a result of breaking accepted protocols, where improperly trained and inadequately equipped divers take on caves well beyond their capabilities. Cave divers maintain that, if the rules and guidelines are followed, their sport becomes acceptably safe. In the rare cases where deaths have happened while following these, there have typically been unusual circumstances, such as unexpected currents or rock falls.
