大学英语六级口语考试分三个部分，第一部分是自我介绍和问答，第二部分是陈述和讨论，第三部分是问答。本场口语考试陈述和讨论的主题为“changing job markets & AI”。随着人工智能技术的发展，有许多人类的工作被人工智能替代。以下展示一篇以“changing job markets & AI”为题的讨论，供考生参考。
Candidate A: Do you know anything about AI?
Candidate B: Yes, of course! Examples of AI are everywhere in our life. We use GPS for locations and directions, robots to clean our houses, and Siri for communication.
Candidate A: Yeah, they are so common in our life. Actually a lot of our work has been replaced by AI.
Candidate B: Yeah, you are right. On the one hand, AI has changed our lives; on the other hand, many jobs are being stolen by AI. Could anything good come of mass unemployment?
Candidate A: In fact, I think the unemployment brought by AI is beneficial to social development. Because with AI, social productivity increases, and people's living standards eventually rise accordingly.
Candidate B: You have a point there. But I still think AI should be developed step by step, the government should not let a large number of people lose their jobs.
Candidate B: I agree with you. Mass unemployment may lead to social unrest.We need to make rational use of the development of science and technology to benefit mankind.
