听力原文：W: Welcome to our program.

M: Thank you.

W: Sam, how long have you been a police officer？

M: I've been a police officer for thirty years.

W: Thirty years. Sam, I think most people would say that being a police officer is a very stressful job. Would you agree？

M: Yes, it's definitely a stressful job. But it depends on your assignment.

W: So, what's probably the most stressful assignment you can have？

M: I'd say patrol is the most stressful assignment.

W: What do you mean, Sam？

M: Well, in patrol work, you don't know from moment to moment who you are talking to or what their reaction is going to be justifying your presence. Let's say, for example, a patrol officer stops someone for a traffic violation. It seems as though that would be a very low-stress situation.

W: Yes, it is a very low-stress situation.

M: But the truth is, there are more police officers injured during a routine stop.

W: Really？

M: Really! That's why all police officers are taught from the very beginning to be aware of their surroundings. So that's probably the most stressful time.

W: I see. Let's take a break and then we'll move on to our next topic.

M: All right.
