听力原文：M: Cindy, what is happiness in your mind? W: Why ask? It's a difficult question. Different people may have different understandings of happiness. M: You said it. But that is the assignment from my psychology professor. W: Well, in my mind, happiness is supposed to be just a state of mind, not so closely related to material life. M: OK. A state of mind. Anything else? W: People ought to value what they already have got. They shouldn't always feel sorry for what they can't have. M: Yes, I agree. But many people often get used to what they have and don't cherish them any more. W: You are right. Maybe people can't be very happy by only staying at one place or staying still at one condition. I mean, if people get what they dream about, or they do better than they expected, they feel happy. And... M: Hold it a second. I need to write what you have said down. Get what they dream about..., better than expected. All right. That's very helpful. Now, let's talk about what kind of specific things or condition that can make people feel happy. Take you for example. W: Well, I said that I didn't mind material things a lot. But if I get some gifts very carefully chosen or made by my beloved relatives or friends, even though they may not be expensive, I would still be very happy. M: So do I. Do you feel this kind of happiness lasts long? W: Of course, whenever I take out the things and look at them, I know there are people who care about me and love me. My heart will be full of happiness. Questions 23 to 25 are based on the conversation you have just heard. 23. What is Cindy's opinion on happiness? 24.
