Divide students into groups of four. Ask them to discuss the three questions on page 41. Get students to exchange their opinions in their own groups. Invite several groups to report their responses back to the whole class.Sample answers1.Yes, with the development of science and technology, human beings could travel wherever they want in the future. The Moon and other planets could eventually bee tourist destinations. Travelling to the Moon or to another planet might be as easy as travelling to another city. You might just have to book a ticket, get packed and think about what present you would like to bring back to your friends on the Earth.2.In my point of view, robots could do almost everything in the future. With the development of science and technology, they may be designed almost the same as humans. They could help people do boring and dangerous work. For example, it would be possible for robots to be lowered to the ocean floor and left to explore the ocean; robots could play an important role in exploration missions to other planets; they could also be the panions of humans and assist humans physically and psychologically, that is , they could perform more useful functions than just as entertainment.3.New technology seems like magic, it can do a lot of amazing things that we could never imagine before. Id like to see that a virtual world could be created with the help of technology so that people could live in both a real world and a virtual one. We could not only play games, travel or experience excitement in the virtual world, but also we could do whatever we cannot do in reality.2. Ask students to think over the question, give them some time to discuss and practice. （PPT page 10，鼠标点击，显示问题）What will our life be like in the future? (an open question) 3.
