听力原文： What happened to me that day is just unbelievable. The first thing to go wrong was that all the parking spaces were taken. So I had to park on the grass, and hoped that I would not get a parking ticket. When I got to the ad- mission office, there was already a long line of students waiting. By the time it was my turn. two of the courses I needed were filled, and I had to go back to my adviser and make out a whole new timetable. Although I did sign up for all my courses, I missed the lunch. The next thing to go wrong was that the bookstore had sold out one of the textbooks required. As I was leaving, I wondered what else could possibly happen, and then there I saw a policeman standing beside my car and writing out a ticket.
