W: Hi, David! Mr. Harper has just asked me if you'd finished your project yet. It was supposed to be handed in yesterday. M: I know. I'm just finishing it now. W: He wanted to know if we'd done them together. I said no. What's yours on? It took me ages to do mine. M: Well, I was really lucky. I found this book all about the population in New Zealand cities. W: Is it good? M: Yes, it's a great book! I photocopied three chapters. There are some brilliant charts and... W: What are you going to do with all that? M: Well, now I'm going to copy these pages and these charts and then I'll finish my project! W: You're not supposed to just copy the book. M: Oh! I think Mr. Harper won't know. W: He will know! He asked us to write a list of all the books we'd used. Remember? That's not the point anyway. M: What is the point then? W: Well, the point is that you're supposed to write your own project--you can't copy someone else's writing. M: Er... er... Well, you're right.
