     "If there is one thing I'm sure about it is that in a hundred years from now we will still be reading

newspapers. It is not that newspapers are a necessity. Even now some people get most of their news

from television or radio. Many buy a paper only on Saturday or Sunday. But for most people reading

a newspaper has become a habit passed down from generation to generation.

     The nature of what is news may change. 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 (基因) 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 (传送) electronically from

Fleet Street and printed out in our own home. In fact, I'm pretty sure that 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- sports and international news, etc.

     I think people have got it wrong when they talk about competition between the different media (媒体).

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.
