     If there is one thing I'm sure about,it is that a hundred years later 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 Saturdays or Sundays. But for most people,reading a newspaper has

become a habit passed down from generation to generation.

     The nature(特征) of what is news may change. What basically makes news is what affects our

lives-the big political stories,the coverage(报道) of the wars,earthquakes and other disasters,will

continue much the same. I think there will be more coverage of scientific research,though,the research

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 (传输)electronically from

the Fleet Street and printed out in our own home. In fact,I'm pretty sure how it will happen in the future.

You will probably be able to choose from a menu and make up your own newspaper by picking out the

things you want to read-say,sports,international news,ect.

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

actually feed-off(依靠) each other. Some people once foresaw(预见) that television would kill off

newspapers,but that hasn't happened. What is read on the printed page lasts longer than pictures flashed

up on a screen or sounds lost in the air. And as for the Internet,it's never really pleasant to read something

just on a screen.

Increasing Noise Annoys

People want action on noise, a recent public meeting in Brisbane showed. Some want technical improvements such as quieter air conditioners or better sound barriers around major roads. Others want tougher laws to restrict noise from building sites or to require owners to take responsibility for barking dogs. But the highest priority (优先) was a noise complaints system that works.

Brisbane City Council receives more complaints about noise than all other problems put together. So it conducted survey and found that about half its citizens are upset by noise in one form or another—traffic, mowers, pool pumps, air conditioners or loud parties. This inspired the Council to bring together more than 100 citizens one evening to talk through solutions to the problem.

The meeting found the present noise complaints system bizarre. Depending on the problem, responsibility for noise can lie with the Council, the Environment Protection Authority, one of three government departments or even the police. So complaints often feel they are getting the run-round. When the people at the meeting were asked to vote for changes, the strongest response was for a 24-hour noise hotline to be the first port of call for all complaints.

The meeting also favored regulatory measures, such as tougher minimum standards for noise in appliances like air conditioners. This even makes economic sense, as noise is a waste of energy—and money. Other measures the meeting supported were wider buffer zones around noisy activities and controls to keep heavy traffic away from residential areas(居民区).
