Make a note of how each discourse marker is used in the interview. While-listening What is discourse marker? Discourse markers are used to organise a text by marking sequence, contrast, opinion, purpose, and so on. Listening for discourse markers can help you understand a text more easily. For example, first, however, above all, in order to etc. Some discourse markers play the role of cue （提示）, pause or transition in a sentence, such as "oh", "well", "now", "then", "you know", and "I mean" etc. to mark the old or shared knowledge; similar to “You know” “You see” to mark contrast to play a role of “pause” or “transition” Task 4: Discourse markers for “changing the topic” When the host moves from introducing the guest to robots and AI... When the host changes the focus to the Three Laws of Robotics... 1. More expressions of changing the topic Oh, by the way, ... Oh, I remember, ... I nearly forgot! ... What I meant to tell/ask you is ... ..., but (perhaps) that's beside the point. （那不是重点） That reminds me of ... The next item on the agenda （议程） is ... I think we ought to move on to ... On the one hand ... On the other hand ... Oh, there was something I meant to tell you. Could I change the subject? What discourse markers do you often use? What are their functions? Thinking Time Function Discourse markers to start or end conversations to change topics to order or sequence to show interest / surprise / sympathy now, so, right, in general, to sum up, for a start, ... what’s more, well, but, however, anyway, ... first (of all), above all, next, ... sure, good, quite, wonderful, exactly, absolutely, certainly, definitely, I see, (all) right, That’s great / interesting / amazing / awful ... Task 4: Listen to the interview again and answer the following questions. 1. What does the expert think about the benefits and problems that robots and AI will bring? 2. In the expert’s opinion, what should we do to tackle the problems? 3. What does the expert think about the future relationship between robots and humans. While-listening Task 4: Listen to the interview again and answer the following questions. 1. What does the expert think about the benefits and problems that robots and AI will bring? The expert believes that robots and AI will bring greater labour efficiency, giving us more time for other things. But the more intelligent they become, the more powerful and dangerous they will be, too. 2. In the expert’s opinion, what should we do to tackle the problems? We need to think carefully about how to programme them to protect us humans. 3. What does the expert think about the future relationship between robots and humans. He thinks the line between humans and robots will be more blurred in the future. While-listening Post-listening 1. Discussion In the interview, the host mentions Issac Asimov’s three laws of Robotics. Are there contradictions among these laws? The laws may be contraditary. For instance, in Issac Asimov’s story “Runaround”, the robot Speedy is ordered to risk his life to do a dangerous job. However, Speedy becomes confused because according to Law 3, he has been programmed not to put his own existence in danger. But if he disobeys the order, it goes against Law 2. Thus, his programming conflicts.
