听力原文：W: Hello, Kevin. I haven't seen you for many days. What's the problem with you？

M: Actually I'm a little embarrassed about coming here. I feel fine right now. (23)But you know, every year around the holidays I would come down with something.

W: (24)So you're interested in prevention. What symptoms do you usually get？

M: You know, cough, fever, runny nose, my head and bones ache etc. I usually feel weak and it ends up ruining my holidays.

W: Sounds like a typical flu to me. (25)Influenza often strikes when people are overtired, stressed 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.

M: (25)I certainly spend a lot of time in department stores around the holidays buying gifts for my family.

W: (25)Yes. And so you increase your exposure to viruses in the air just when your body's resistance is already low.

M: So what can I do to prevent from the flu？

W: Actually it's fairly simple. Get a lot of rest and eat well. That way your body will become stronger. And you'll be more able to fight off illness.

M: All these things make sense. But one more question. Am I bound to get sick anyway if there's an outbreak in the dorm？

W: I'd also suggest you get immunized. It prevents the three main types of influenza.

M: I'll do it right away. It will be nice to feel well during the holidays for once. Thank you so much, doctor.

W: That's all right.
