听力原文： Dangerous occupations tend to be exciting and well paid. They often involve foreign travel or meeting famous and interesting people. Here is a look at someone who likes his dangerous occupation in spite of the danger, and at why he does it. Gilbert Michael Pitts is a freelance cameraman. He does a lot of his work underwater. Michael has been diving since he was about nine years old. He says that he was on holiday with his parents and a friend had a snorkel. He tried it and 'that was it—ever since I first put my head under water I've been fascinated by divining'. Later on he went on a four month commercial diving course. His commercial diving career included underwater photography—still and video (to inspect oil rigs), underwater burning, planting explosives and connecting pipelines. 'I'm not frightened or apprehensive,' he says, 'because it's a medium I've been working in for such a long time. It's something that I love. I am frightened of certain things, but they certainly don't include diving in water. I think it's a matter of experience and just being at ease in that environment. ' (33)
