单选题 I was very disappointed not to be able to go to the jazz (爵士乐) concert last Friday. The advertisement (广告) in the paper said that you could buy tickets at the theatre box in Richland Hills any day be- tween 10:00 and 4:00. Since I work from 9:00 to 5:00, the only time I could go to the theatre was during my 45 minutes lunch break. Unfortunately, the theatre is on the other side of the town, and the bus service between my office and Richland Hills is not very good. But if you are lucky (幸运的) , you can make the round trip in 45 minutes. Last Monday, I stood at the bus stop for fifteen minutes wait- ing the bus. By the time I saw one come around the corner, there was not enough time left to make the trip. So I gave up and went back to the office. The same thing happened on Tuesday, and again the next day. On Thursday, my luck changed. I got on a bus right away and arrived at the theatre in exactly twenty minutes. When I got there, however, I found a long line of people at the box office. I heard one man say he had been waiting in line for over an hour. Realizing I would not have enough time to wait in line, I caught the next bus and headed back across the town. By Friday I realized my only hope was to make the trip by taxi, it was expensive, but I felt it would be worth it to hear the concert. The trip by taxi only took 10 minutes, but it felt like an hour to me. When I got to the theatre, I was relieved to see that nobody was waiting in line. The reason, however, I quickly dis- covered, was that they had already sold all the tickets.
