听力原文：M: Hi, Janet, you're so lucky to be done with your final exams. I still have 2 more finals to take.
W: Oh, really？
M: Yeah. So do you have any plan for the summer？
W: Actually, I do. My parents have always liked taking me to different places of historical significance.
M: I guess they want to reinforce the stuff you've learned in school about history. So where are you going this summer？
W: Well, this summer it's finally going to be Gettysburg.
M: Finally？ You mean you've never been there？ Gettysburg is probably the most famous civil war site in the country; and it's only a couple of hours away.
W: We had planned to go there about ten years ago, but we ended up not going anywhere that year.
M: What happened？
W: Don't ask me what it was. You know, I was too young to remember... Anyway, I hope that doesn't happen again this year.
