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 lea rn 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 evenwe 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.。
