听力原文：M：Good morning，I'm doing a survey for the Department of Health and Social Security and I'd like to ask you a few questions if I may. W: I suppose that'll be OK. M: The first question is what is your full name? W: Louisa O'Leary. M: And your age, Mrs. O'Leary? W: Well ... it's thirty-four. M: Really? You don't look it at all. Now how much does your husband earn? W: That's a personal question, but I suppose I should try and be as frank as I can with you--￡ 10,000 a year. M: That isn't much. W: Yes. M: Now what I'm really interested in is the way you spend your money. What about housiug, for example? W: Well, our house costs us about ... er, ￡ 300 a month. M: Oh, that must be difficult with ten thousand a year! W: It certainly is. I was working before we had the baby, of course. That used to make things a lot easier. Now we're much less well off. M: Mm. Apart from the house, where does your money go? W: Food is the biggest item. That's about ￡ 240 a month for food and other small bits and pieces-cleaning materials and so on. For electricity, we only use it for lighting. That's about ￡ 50 a year. (23)
