A、A trainee nurse. B、A resident doctor. C、A researcher of AIDS. D、An advisor to nurses. A对话开头，男士问候苏珊在艾滋病房的第一周怎么样，苏珊说她从没有想到护士要做那么

M: Hi, Susan. How’s it going? How was your first week in the AIDS ward?
W: OK, I guess. [1] But I never realized how many different things nurses have to do. There is a lot to learn.
M: There sure is! That’s why we’re having this meeting today, Susan. As your advisor, it’s my responsibility to [1] help you learn your new job. We’ve found that sometimes our new assistant have trouble adjusting to the AIDS ward.
W: Actually, I do feel worried about being here.
M: That’s normal. I felt the same way when I started. What are you nervous about?
W: I know it sounds dumb, but I keep thinking that I might get infected with HIV. I know there isn’t a very big risk, but I’m still worried. My friends are worried, too.
M: What are your friends saying?
W: Well, some of them don’t want to be around me now. I think they’re afraid that they’ll get HIV
somehow. [2] One friend always used to give me rides in her car, but she won’t drive me to work because she’s afraid I’ll get the virus in her car!
M: That’s a difficult situation. But it’s a good opportunity to teach your friends the facts about HIV and AIDS, so they’ll know they’re wrong. And if they don’t want to learn anything, maybe they aren’t good friends. I know I lost a few friends when I started working here.
W: [3] My family’s also worried. My mother keeps saying, "You can’t be too careful!" [3] She’s afraid that I’ll get AIDS from a patient. So I try to be very careful. I always wear the protective clothing, you know — the rubber gloves, paper clothing, and plastic glasses. But then something strange happened.
M: What happened?
W: I went in to see a patient, to bring him his lunch, and he looked at me and said, "Oh, you’re new here, aren’t you?" Then he was acting very angry at me after that. I think it was because of the
clothing!
M: Why do you think he was angry?
W: I’m not sure. I was just trying to protect myself.
M: I think the important thing to remember when you’re working with AIDS patients is that you’re working with people — people who are very sick, [4] but who still need to be treated with respect. I remember what my boss told me when I first started working with AIDS patients. He said, "It’s important to isolate the AIDS virus, but not the AIDS patient."
W: So what should I do?
M: Well, you have to think carefully before you go into someone’s room. We know that it’s impossible to get AIDS from just touching someone, or breathing the air next to them, or ever sharing a glass of water. [5] AIDS, as you know, is passed through blood or bodily fluids.
