Question 23 is based on the passage you have just heard

听力原文：

    Where do you think you’ll be in ten years? It’s difficult to know exactly where you will be, and what you will be doing, (22) but everyone dreams about the future.

    You might imagine the job you will get when you finish school. You may daydream about meeting your life partner, or living in a big house by the sea. In my dreams, I would have twins, a boy and a girl. We would live in a large two-story house with floors and a staircase made of wood.

    Now, at the age of 46, I look back on those dreams and smile. (23) Things haven’t turned out exactly as I imagined, but I wouldn’t change what I have now for that imaginary world.

    (24) In college, I studied international business, and planned to enter a law school. In my third year of university, I realized that I didn’t want to become a lawyer. Instead, I chose to become a language teacher. I did get married, but had more than two children. We had five. Do I live in the dream house with wooden floors? No, I don’t, but I love my home and I wouldn’t want to live in any other place.

    I believe that as a young person, it is important to dream and make plans. However, it’s also important to realize that not all of your plans will turn out exactly as you wish. (25) One of the biggest lessons I’ve learned in life is this: be happy with what you have.

23. What does the speaker say he would refuse to do?

解析：B。本题为细节题。问题为：说话人说他会拒绝做什么？根据原文“Things haven’t turned out exactly as I imagined, but I wouldn’t change what I have now for that imaginary world.”，可见事情并非完全与说话人的想象一样发展，但说话人不想将现在拥有的东西(what I have now)换取梦想的世界(imaginary world)。选项B) Change what he has for his past imaginary world.是对原文的同义转述，根据视听一致原则，为正确答案。
