听力原文:M: Hello, Ann. I haven't seen you in a while. What seems to be the problem?
W: Actually I'm a little embarrassed about coming here. I feel free right now, but you know how much stuff is going around. Anyway every year around the holidays like clockwork I come down with something.
M: So you're interested in prevention. What symptoms do you usually get?
W: You know, cough, fever, runny nose, my head and bones ache, chills even. I'm usually miserable for a week and it ends up ruining my holidays.
M: Sounds like typical to me. As you said, lots of people get it when they're overtired, stressed out and not eating nutritious food. And also you increase your exposure to a virus when you're in big crowds where lots of people are coughing and sneezing.
W: I certainly spend a lot time in department stems around the holidays buying gifts for people.
M: Yes. And so you increase your exposure to airborne viruses.
W: So what can I do to ward off the flu?
M: Actually it's fairly simple. Get a lot of rest and eat well. That way your immune system will be boosted. And you'll be more able to ward off illnesses.
W: All these things make sense. But one more question. Aren't I bound to get sick anyway ff there's an outbreak in the dorm?
M: Oh, you didn't mention you lived in the dormitory. In that case I'd also suggest you get immunized. The vaccine available prevents the three main symptoms of influenza. Why don't you go to the university health center? The shots are free them.
W: Really! Thank you. I'll do it right away.
