听力原文： It arrived on a Friday afternoon. The idea probably originated somewhere over the Atlantic, off the coast of Africa. It came across the world, until it finally found me, stuck in traffic, and flew through my ear into my head. And I knew exactly what I wanted to do with my life. History had always been my academic passion. I've read so many history textbooks, I've sat down and read countless encyclopedia articles, books and websites, and I've watched more hours of the History Channel than anyone I've ever met. 1 know that I want to have a hand in guiding the progress of my nation and world. My passion for history has only been matched by my love of mental competition. I live for arguments, debates and discussions. The points and counterpoints come out hard and fast. I make my statement and discredit that of my opponent, I respond, I parry, I dodge. I feel content, happy and fulfilled. These two ideas found their way to me on that Friday afternoon, a profession that would combine my two passions: Campaign Management. My love for mental combat would Be used to its fullest in matching wits with the opposing campaign staff, and my passion for history would be more than sated by my involvement in what I consider to be its most interesting aspect: its creation. Through campaign management, I would be indirect ly shaping history. Many of my friends don't know where they want to go to school, they don't talk about where they stand in the class, how good, or bad their scores are. People ask me the same questions, and I face them with confidence, because I know the answer to a larger question: I know where I want to be when I'm done with college.
