听力原文：W: Oh, hi, Daniel. Are you going to the in-service gaining today? M: You bet. I missed the training session last month, so I have to be sure to make this one. Aren't you excited about the program? W: Not really. Before I became a nurse I drove an ambulance and had a lot of emergency medical training. Practicing basic first aid techniques is a kind of boring for me. M: Well I can understand that. But you know, it's amazing how quickly you get out of practice. As nurses in a hospital, we have all the fancy equipment for medical emergencies-and plenty of doctors around, so we hardly ever get a chance to practice basic techniques. They're really easy to forget. And you know that practice makes perfect. W: I can see your point, and it never hurts to review what you're already supposed to know. By the way, who's teaching the class this time? M: Dr. Huston. She's the new emergency room physician. W: Well, she certainly ought to know what she's talking about. I've heard she's a really good surgeon. M: That's right. I've been taking care of some of the patients she worked on, and they all think highly of her. W: When are you going to head over to the classroom? M: Immediately. I'm just on my way there. Do you want to walk over together? W: That sounds good to me. Let's go and prepare for the training. (20)
