听力原文： There is a strange area in the Atlantic Ocean called the Bermuda Triangle. People have been fascinated by the Bermuda Triangle for years, because of the mysterious disappearance of many ships and planes in the area. There is hardly any agreement about the cause of these disappearance, in fact, it is difficult to find any agreement about the boundaries of the area. Whereas most people argue that the triangle's northern most point is Bermuda, its western most point is Florida, and its eastern point is the coast of Africa, a few researchers prefer the northern point to be in the Boston area.
