Virtual Reality

Tom: Hi, Cathy. What are you up to this weekend?

Cathy: Don’t ask, Tom. I have lots of work to do. If I don’t finish my project on the history of the Internet for next Monday’s lesson, the science teacher will be angry. What about you? Do you have anything planned for Saturday and Sunday?

Tome: It depends on the weather. If it’s good, Dad, Mum and I will probably go camping. But we won’t go if it rains. Hey, if I stay home, I’ll help you with your project if you like.

Cathy: Thanks for the offer. Tom, can you suggest any good books for my projects? If you tell me some titles, I’ll look for them in the library.

Tome: Use the library computer. If you go to the Science Museum website, you’ll find lots of good information. I’ll send you the website address when I get home.

Cathy: Thanks. Just think, if we had virtual reality holidays, we wouldn’t have any problems with the weather. What’s more, we wouldn’t have to spend a long time travelling on planes to get to our holiday destinations.

Tome: What do you mean?

Cathy: Well, in the future, we’ll be able to use modern technology to go anywhere we like. We won’t have to go there in the flesh at all! Wouldn’t that be great? I feel excited just thinking about it.

Tome: I don’t understand. Cathy, do you mean we’ll use the computer to travel around the world, entering and exiting countries in seconds and visiting all the historical sites!

Cathy: That’s right! Just imagine never having to pack a suitcase! We would not only be able to travel around the world, but also go to study in any world famous universities we wanted to .

Tome: That could be really exciting! But I still find it hard to imagine. You would see it but you couldn’t dip your toes in the sea or eat the foods you saw. You would not experience it.

Cathy: Well, if they invented virtual reality holidays, I’d go on an around-the-world tour. Tom, what would you like to do if someone gave you the chance?

Tom: I don’t really know. Personally, I’m more interested in virtual universities than virtual reality holidays. I’d like to go to a world-famous university like Stanford. But I guess, a virtual university just wouldn’t be the same, would it?

Cathy: True, but just think—you would be able to study in such a world-famous university without going out of your room!
