Period 4 Using language
1. Do you know dinosaurs? Where have you seen them? Can you see them in our real life? Why?
2. Do you think it is possible to clone dinosaurs? If yes, do you think that’s good for human beings? Why?
S1: No, indeed. I know it’s a bird like the Great Auk but neither of them could fly. So if you kept either, it wouldn’t escape from a park, a family or its home in the wild. You could also farm a dodo, unlike all the others and produce many of them as exotic pets. S2: And what about its large nutritious egg? Just one would feed a large family. So there’s more than one reason for producing it in commercial numbers. S1: Did you know that its meat is very tasty too? Perhaps it could be farmed like ostriches and provide a good source of protein.
