Conversation Two
W: Good morning, Dr. Smith. I'm not sure whether you can help me or not, but I'm getting desperate!
M: Oh, what's wrong? What is making you so desperate?
W: [24]Well, everybody laughs at me because I'm so fat. I've always been overweight. I'm trying to eat less but I don't seem to be able to lose any weight. I don't know what I can do. Maybe you can give me some medication?
M: [25]Well, it is not a good idea to eat less. You should eat more healthy food like fruits and vegetables, and avoid fast foods like the hamburgers and hot dogs.
W: But hamburgers and hot dogs are my favorite.
M: That's the problem. They contain high calorie that causes fatness. In addition to avoiding these high calorie foods, you should do some exercises. Physical exercise does a lot of good to health and will be an effective way to reduce weight. Medicine is not always the best solution to your problem.
W: I know, but I don't have time to do exercise. You know, I'm busy at my work from morning to night. Besides, I am not rich enough to go to the gym.
M: You needn't spend much time on exercise and you don't have to go to the gym. I suggest that you walk more regularly. You could get off the bus one stop early and walk the last bit. When you walk, try to walk a little more quickly. You could also use the stairs instead of the elevator.
W: That's really a good idea.
M: You will succeed, if you act in accordance with my suggestions.

Questions 23 to 25 are based on the conversation you have just heard.
23. What are they talking about?
正確答案：C
解析：主旨題。對話開始女士便提到她很胖，食物和運動等相關信息都是針對女士的肥胖問題提出的解決方法。說話人談論的焦點始終是怎樣才能瘦下來，因此C項正確。A項和B項是醫生的建議，D項是女士最初想采用的方法。
24. Why does the woman feel desperate?
正確答案：A
解析：細節題。醫生問“什么使你如此絕望”，女士立刻做出正面回答：“因為我非常胖，所以每個人都嘲笑我。我總是超重。我在試著少吃些，但體重似乎一點都沒減輕。”選項A是其同義表達，故正確。C項和D項的內容對話中提到了，但并非女士感到絕望的原因；B項與女士的態度相反。
25. What is not the man's suggestion?
正確答案：A
解析：細節題。男士不贊成靠節食減肥，也不打算給女士開藥，他提議少吃快餐，多吃蔬菜水果，多做運動。因此答案為A。
