听力原文：M: Hi, Janet, you're so lucky to be done with our final exams and term papers. I have two more finals to take.
W: Really？
M: Yeah, so what are you doing this summer, anything special？
W: Well, actually yeah. My parents have always liked taking my sister and me to different places in the United States. You know, places, with historical significance. I guess they wanted to reinforce the stuff we learned in school about history. And so even though we are older now, they still do once in a while. Oh, so where are you going this summer？
M: Well, this summer it's finally going to be Gettysburg.
W: Finally？ You mean they never took you yet？ I mean Gettysburg, it's probably the most famous civil war site in the country, and it's only a couple of hours away. I think that would be one of the first places that they've taken you. I have been there a couple of times.
M: We were gonna to go about ten, well, no, it was exactly ten years ago, but I don't know, something happened, I cannot remember what.
W: Something changed your plans？
M: Yeah, don't ask me what it was, but we ended, up not going anywhere that year. I hope that doesn't happen again this year. I wrote a paper about Gettysburg last semester for a history class I was taking. Well about the political situation in the United States right after the battle at Gettysburg, So I'm eager to see the place.
