听力原文：W: Oh, hi, Daniel. (19) 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. (19)(20) 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. (21) 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.
