Lead-inT:From the text , we know that RealCine uses new technology to improve an existing type of entertainment. Could this technology be used in some other ways? Now, work in pairs and discuss with your partners. Five minutes later, I will collect your answer.S1:I think it should be used to meet people all over the world. We have friends in many other places. Since we are busy studying at school, we don‟t have much time to communicate with our friends. If we can use this technology, we can communicate with our friends more often.S2: I think it should be used to train drivers. As we know, private cars are becoming more and more popular among common people. To have access to driving cars, we should first get the driving license. For example, my dad has to go to the driving school once a week . But he is so busy that sometimes he couldn‟t take the classes. If the virtual reality can be used in our home, we needn‟t spend the valuable time going to the driving school. We just learn the skill at home.T: Good idea! Thank you! You are really imaginative.
