[originaltext]M: I fell off my bike last week, and my back is still hurting now

M: I fell off my bike last week, and my back is still hurting now. I wonder if I should go to see a doctor. What would you say?
W: Well, it might be an internal injury. I think you want to go make sure that there is nothing wrong with your back.
Q: What does the woman mean?

W: I couldn’t get hold of Tom to tell him about the ticket I got for him. His cell phone is always unreachable. Has he changed his phone number?
M: I don’t think so. But I will see him at the history class tonight, and probably I can pass it to him if you don’t mind.
Q: What do we learn from this conversation?
