[00:-1.00]The Future of Cyberspace
[00:-2.00]Peter Taylor finds out how computers
[00:-3.00]and the internet are going to affect our affect our lives.
[00:-4.00]In the last thirty years,the Internet has grown dramatically.
[00:-5.00]In 1983, there were only 200 computers connected to the Internet;
[00:-6.00]now there are around 50 million and this growth is clearly going to continue.
[00:-7.00]Some experts are pessimistic about the future.
[00:-8.00]One worry is the activities of cybercriminals.
[00:-9.00]Even now,young hackers can get into the computers of banks and governments
[00:10.00]In the future,cyberte-rrorists may 'attack the world's computers cause chaos,
[00:11.00]and make planes and trains crash.
[00:12.00]However,many people are optimistic about the future of the Internet.
[00:13.00]Already, users can buy books, find out about holiday offers,
[00:14.00]book tickets,and get all sorts of information from the Internet.
[00:15.00]'In the next few years,' says Angela Rossetto of Cyberia magazine,'
[00:16.00]it is clear that we are going to see an explosion of shopping on the Internet.'
[00:17.00]She also believes that, in the future,
[00:18.00]we will get entertainment from the Netand
[00:19.00]that television will probably disappear.
[00:20.00]The postal service may also disappear with the increasing use of e-mail.
[00:21.00]Some specialists see our future in virtual reality
[00:22.00]the use of computers with sounds and images
[00:23.00]that make you feel as if you are in a real situation.
[00:24.00]'Personally, I think virtual reality will become a part of modern life,'
[00:25.00]says Australian expert Peter Anderson'I see people living
[00:26.00]and working in a virtual world.
[00:27.00]We will work in virtual offices, shop in virtual supermarkets,
[00:28.00]and we will even study in virtual schools.'

[00:30.00]Virtual Reality Tom: Hi, Cathy.
[00:31.00]What are you up to this weekend? Cathy:Don't ask, Tom.
[00:32.00]I have lots of work to do.
[00:33.00]If I don't finish my project on the history of the Internet
[00:34.00]for next Monday's lesson, the science teacher will be angry.
[00:35.00]What about you? Do you have anything planned for Saturday and Sunday?
[00:36.00]Tom: It depends on the weather.If it's good.
[00:37.00]Dad, Mum and I will probably go camping.
[00:38.00]But we won't go if it rains.
[00:39.00]Hey, if I stay home,I'll help you with your project if you like.
[00:40.00]Cathy: Thanks for the offer.
[00:41.00]Tom, can you suggest any good books for my project?
[00:42.00]If you tell me some titles, I'll look for them in the library.
[00:43.00]Tom: Use the library computer.
[00:44.00]If you go to the Science Museum website,you'll find lots of good information.
[00:45.00]I'll send you the website address when I get home.
[00:46.00]Cathy:Thanks,Just think,if we had virtual reality holidays,
[00:47.00]we wouldn't have any problems with the weather.
[00:48.00]What's more,we wouldn't have to spend a long time travelling
[00:49.00]on planesto get to our holiday destinations.
[00:50.00]Tom:What do you mean?
[00:51.00]Cathy: Well, in the future,we'll be able to use modern technology
[00:52.00]to go anywhere we like.Wouldn't that be great?
[00:53.00]I feel excited just thinking about it.
[00:54.00]Tom: I don't understand.
[00:55.00]Cathy, do you mean we'll use the computerto travel around the world
[00:56.00]and visit all the historical sites?
[00:57.00]Cathy: That s right! Just imagine it.
[00:58.00]We would not only be able to travel around the world,
[00:59.00]but also go to study in any world famous universities we wanted to.
[-1:00.00]Tom: That could be really exciting! But I still find it hard to imagine.
[-1:-1.00]Cathy: If they invented virtual reality holidays,
[-1:-2.00]I'd on an around-the-world tour.
[-1:-3.00]Tom, what would you like to do if someone gave you the chance?
[-1:-4.00]Tom: I don't really know.
[-1:-5.00]Personally,I'm more interested in virtual reality universities
