听力原文: For most people, reading a newspaper has become a habit passed down from generation to generation. I'm sure in a hundred years we will still be reading newspapers.
What basically makes news is what affects our lives -the big political stories the coverage of the wars, earthquakes and other disasters will continue much the same. I think there will be more coverage of scientific research, though. It's already happening in areas that may directly affect our lives, like genetic engineering. In the future, I think there will be more coverage of scientific explanations of why we feel as we do - as we develop a better understanding of how the brain operates and what our feelings really are.
It's quite possible that in the next century newspapers will be transmitted electronically from Fleet Street and printed out in our own home. In fact, I'm pretty sure that is how it will happen in the future. You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read.
I think people have got it wrong when they talk about the competition between the different media. They actually feed off each other. Some people once foresaw that television would kill off newspapers, but that hasn't happened. What is read on the printed page lasts longer than pictures on a screen or sound lost in the air. And as for the Internet, it's never really pleasant to read something just on a screen.
