听力原文：W: Good morning, Housing Office. How can I help you？
M: Hi, I' m calling about the new subsidized, low-cost housing for graduate students.
W: Are you aware that it' s only available to married graduate students and their families？
M: Yes, I think my wife and I may qualify, since she' s still in graduate school. But I was wondering whether there were any other requirements.
W: Well, unless you have more than one child, you have to have a combined annual income that' s less than fifteen thousand dollars.
M: I' m working as a part-time research assistant, so that' s no problem! But right now we' re living with my wife' s parents. Does that mean we' d have to include their income, too？
W: Not necessarily. Why don' t you stop by our office, so I can give you some forms to fill out and explain everything in more detail？
M: That sounds like a good idea. Would tomorrow morning be all right？
W: The afternoon might be better. It can be pretty crazy around here on a Friday morning.
M: All right then. I'll try to make it in the afternoon. Is there anyone special I should ask for？
W: You can ask for me, Susan Davidson, or my assistant, Bill Brown.
