How do you think these events or such technology might develop in the future? 2. What challenges might they bring? 3. What opportunities might they bring? No doubt, AI will develop to the point that humans and computers will be able to interface effortlessly. With the development of AI, there may come a time when it becomes a real issue as to whether a computer or machine has in fact achieved consciousness, and whether, as a conscious being, it deserves the same rights as a human being. AI may help us solve problems that are currently too big and overwhelming for us to solve on our own. For example, complex AI models may be able to use given data to develop a workable solution to global warming. Pre-listening 03.

That’s very interesting. But aren’t you worried that …? Wow! That would make each one of us superhuman! Oh, really? What might …? That sounds very innovative. While Listening Host: On today’s episode of “Future Changes”, we talk with two experts from different fields, Dr. Han and Vincent Black, to hear their predictions about the future. First, Dr. Han, could you please tell our audience what you do? Dr. Han: Certainly. I’m a computer scientist. Host: And could you please tell us your prediction? Dr. Han: Yes, well. I forecast that computers will be cleverer than us in the future. I think that people will also be programming computers to think like humans. Host: That’s very interesting, but aren’t you worried that such computers would be dangerous? Dr. Han: Not at all. This is because we’ll be programming them to not think in ways that may harm humans. In fact, we’ll also be creating machines to help people internally. For example, I think scientists will put some small intelligent machines, called nanobots, inside our bodies to increase our abilities. Host: Wow! That would make each one of us superhuman! And Vincent, could you please tell us about your job? Vincent Black: Certainly. I’m an architect. I design buildings. Host: And what is your prediction about the buildings of the future? Vincent Black: It’s about the cities of the future, actually. I believe that cities floating on water are part of the world’s future. Host: Oh, really? What might make us want to do that? Vincent Black: Yes. With global warming causing polar ice to melt, the sea level rising by many metres is a very realistic prospect. Instead of moving people away from the sea, I think that people could move into housing in cities that float. Host: That sounds very innovative. Could you please give us more details? Vincent Black: Sure. Well, I’ve developed a plan by designing a city that borrows many ideas from the giant water lily, a flower that floats on water. Moreover… 16 04.

Thank you for agreeing to do this interview. B: I'd love to. A: First, could you please tell our audience what you do? B: Certainly. I'm a doctor. I perform transplant surgery every week. A: That sounds like a very high-tech job. How do you think the surgery will be operated in the future? Do you have any predictions about that? B: Yes, well, I believe that doctors in the future will have much better means to help people. I can imagine that nanobots will be put in patients' body to detect the illness. And in the future, there will be adequate supply of organs for patients who need transplant. A: Well, that would be really good news for all of us. Could you please explain how this will be possible? B: Well, it will be possible because of special 3D printers. In the future, doctors will be using them in hospitals regularly to create healthy copies of people's organs. Then they will replace the unhealthy organs with the healthy copies. Sample Dialogue Post Listening 05.

Assignment Writing Task: Should Students Use AI Tools for Homework? 随着DeepSeek等人工智能应用的流行，越来越多的学生频繁使用AI来完成作业。校英文报就此现象展开讨论，请你投稿发表看法。内容包括： 1. 你支持还是反对使用AI完成作业？ 2. 简要说明你的理由。 Assignment Should Students Use AI Tools for Homework?

In today's digital era, AI tools like DeepSeek have become increasingly prevalent in education. While some worry about over-reliance, I firmly believe that when used properly, these tools offer valuable academic support. First, AI provides immediate access to relevant information, helping students overcome learning challenges efficiently. For example, when struggling with complex math problems, learners can receive step-by-step AI explanations instead of remaining stuck for hours. Moreover, by combining AI assistance with traditional study methods, students can personalize their learning pace while developing critical thinking skills. However, moderation is key. Students should analyze AI-generated solutions thoroughly rather than copying them blindly. With proper discipline, AI not only makes learning more efficient but also fosters independent problem-solving abilities. When used as a supplementary tool rather than a shortcut, AI can significantly enhance educational outcomes. Assignment 47 Possible Version 2: Opposing AI Use (Cons) Should Students Use AI Tools for Homework? As high school students, we cannot deny the convenience AI tools like DeepSeek bring to our studies. However, we must recognize that excessive reliance on them may do more harm than good to our academic development. What concerns educators and students alike is how AI dependency fundamentally alters the learning process. When we command AI to generate instant answers, we sacrifice the opportunity to engage in critical thinking - the very skill that standardized tests and future careers demand. Research shows students who overuse AI for homework score 15-20% lower on exams, proving that instant access to answers doesn't translate to knowledge retention. Furthermore, in the absence of genuine effort, we fail to develop problem-solving strategies or the ability to concentrate on complex tasks. My physics teacher often warns that students who rely on AI solutions struggle with experimental design, as they haven't developed the necessary analytical skills through practice. Therefore, while AI can be a useful reference tool, we must resist making it our first choice for completing assignments. After all, genuine learning occurs only when we concentrate on the thinking process instead of seeking instant solutions.
