    I was taking a train to London's Victoria Station. I had noticed that the carriage was noise and filled with people.

    Before long, a train inspector comes to check out tickets. A passenger realized he couldn't find his ticket but became quite upset. Then everyone in the carriage began searching the ticket, which was eventually found under a seat several rows from his owner. The person who found a ticket smiled with pleasure at his success.

    No one in the carriage had previous spoken to or even noticed the ticket-owner before. Yet, they had so quickly offered the strangers their help. If we could show concern to others on need, the world would be a better place to live in.

    Robert is nine years old and Joanna is seven. They live at Mount Ebenezer. Their father has a big property. In Australia they call a farm a property.

    Robert and Joana like school very much. At school they can talk to their friends, but Robert and Joanna can not see their friends. They live 100,perhaps 300,miles away and like Robert and Joanna, they all go to school by radio.

    Mount Ebenezer is in the centre of Australia. Not many people in “The Centre”, there are no schools with desks and blackboards and no teachers in “The Centre”.  School is a room at home with a two-way radio. When all students answer, lessons begin.

    Think of your teacher 300 miles away!

    "If there is one thing I'm sure about, it is that m 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（基因的） 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 how it will happen m 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.
