98. Speaking from the Grave Two students， Beth and Carl， are talking about the red-haired mummies. B： Can you imagine what it was like 4，000 years ago？ C： That s hard to imagine. But if the mummies could speak， they could certainly tell us a great deal. B： Well， that， of course， is impossible. But scientists can tell a lot from the things the explorers found. C： I know. For example， they think the 4000-year-old mummies were Celts. B： Who were the Celts？ C： They were ancient European people who settled in Britain even before the Romans existed. B： Wow！ That s amazing！ C： So you see， although mummies don t really speak， they are "speaking" from their graves. B： Stop it！ you re giving me the creeps！
