Read the text and questions below. Choose the correct answer Not only does Linda Greenlaw do one of the most dangerous jobs in the world, but she also does it extremely well. She has been described as "one of the best captains on the entire East coast" and that, in one of the leading countries in fishing industry, is praise indeed. Linda was born and brought up on Isle au Haut, a tiny island ten kilometers off the coast of Maine, USA. She fell in love with fishing as a child, and she worked on fishing boats during her summer breaks from college. Her first opportunity to go on a deep-sea fishing trip came when she was nineteen. Alden Leeman, a man she'd never met before hired her for thirty days on his sword fishing boat. The trip was a success and eventually Alden offered Linda her first boat to captain in 1986, which probably made her the only woman ever to captain a sword fishing boat. So, why did she take up sword fishing in the first place? Linda says that not only does she like the way she feels on a boat, but she also gets passionate about catching a fish. More than anything she's proud of being a fisherman, even more so than she is of being a best-selling author. Linda has published four books to date, the first of which, The Hungry Ocean, was top of the New York bestseller list for three months. In it, Linda tells the story of one fishing trip and narrates the adventures she experienced on board with her five-man crew, including bad weather, sickness, mechanical problems and, of course, the fish. But the world of fish and fishing is a man's world and it's not easy to find a word to describe Linda Greenlaw. In her own words, she says: "I am a woman. I am a fisherman not "a fisherwoman", "fisherlady" or "fishergirl". 1. Linda is ______. A. American B. British C. Canadian D. Hungarian 2. Her first-deep fishing trip was ______. A. when she was a child. B. before she was twenty C. in 1986 D. before she was nineteen. 3. Linda took up sword fishing because ______ . A. she needed to earn some money. B. all her family are fishermen. C. she loves boats and catching fish. D. she fell in love with a fisherman. 4. On the boat described in The Hungry Ocean ______. A. there were six men B. there four people C. there were five people D. There were six people 5. Linda prefers to be described as a ______. A. a fishwoman B. a fisherlady C. a fisherman D. a fishergirl
