Voice your opinionSuppose that you could go to University of Science and Technology of China, which is physical. Meanwhile, you could also attend Stanford through virtual university to get your degree. Which one would you choose? ( some cues are shown on the screen)Step IV: Teacher’s summaryNow class, virtual reality technology can change our life to some extent, On the one hand, we enjoy the convenience and excitement it brings to us, on the other hand, we should restrain our dependence on virtual world, young people shouldn’t be addicted to virtual computer games, as for virtual holidays we just see the scenery and can’t experience the pleasure of travelling with your families and friends. In terms of virtual university you can learn some professional knowledge in one field, but don’t forget that learning how to improve your social skills and communicate with different sorts of people is an indispensable part of college education, meanwhile, the learning atmosphere of a university is of great significance to your success. Just think if so many people can study in world famous universities through virtual university, those famous universities will become a “degree factory”. Don’t you think that the value of your degree from the university will be at a discount? So even we have virtual university in future, some specific requirements are still needed for some universities, especially, world famous university. Now class I think you have a better understanding of the advantage and disadvantage of virtual reality, so we should be optimistic about the future of virtual reality, and keep a positive attitude toward study and life.Step V: AssignmentHaze weather in Hefei is very serious now, Do you have some good suggestions? Write a short passage about what you would do to reduce it, if you were the mayor of Hefei.。

Unit4 Cyberspace Lesson3 Virtual RealityTom: 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 myproject on the history of the Internet for next Monday’s lesson, the scienceteacher will be angry. What about you? Do you have anything planned forSaturday and Sunday?Tom: It depends on the weather. If it’s good, Dad, Mum and I will probablygo camping. But we won’t go if it rains. Hey, if I stay home, I’ll help youwith your project if you like.Cathy: Thanks for the offer. Tom, can you suggest any good books for my project? If you tell me some title s, I’ll look for them in the library.Tom: 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 destination s.Tom: What do you mean?Cathy: Well, in the future, we’ll be able to use modern technology to goanywhere we like. We won’t have to go there in the flesh at all! Wouldn’tthat be great? I feel excited just thinking about it.Tom: I don’t understand. Cathy, do you mean we’ll use the computer to travel around the world, entering and exit ing countries in seconds and visiting all the historical site s?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. Tom: That could be really exciting! But I still find it hard to imagine. You would see it but you couldn’t dip your toe s 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 virtualuniversities than virtual reality holidays. I’d like to go to a world-famousuniversity, like Stanford. But I guess, a virtual university just wouldn’t be thesame, 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.参考译文：虚拟现实汤姆：你好，凯西。
