W: Hello, Dan. I was sorry to hear that you had an accident last week. How did it happen and how are you feeling now?
M: Well, I was riding on my bicycle along the street when a taxi driver suddenly made a sharp turn in front of me. I could not stop my bicycle in time and I was knocked down. Fortunately, I only got a broken arm and a broken leg. The doctor said that I would have to stay in hospital for at least a week.
W: Do your arm and leg hurt now?
M: Yes, my leg hurts badly, but I can bear the pain. The only thing that I'm worried about is my classes. You know, next week we're going to have our mid-term exams.
W: Well, don't worry about the exams. I can help you.
M: Thank you, but I don't really want to stay here that long. Anyway, thank you for coming to see me.
