单元主题回顾
Some best-selling authors and their partners use outer space as their topic.The creative sci-fi stories or videos are full of predictions about life in the future.Some imagine a world where technology makes our transport system really efficient,with today's public traffic disappearing.It's impossible for everyone to be a pilot now,but it could be in the future.
However,not all predictions are positive. There are fears(害怕)of disasters or emergencies that could make the world a worse place.Some stories even talk about evil forces(邪恶势力)everywhere trying to take over the earth.
Technology influences our quality of life.Medical technology is developing quickly.It makes us the winners to cure cancer and extends( 延 长 )our length of life.Futurists,who are the experts in predicting the future, mention that AI might change our lives,from education to industry.
Creativity and emotional intelligence will be valuable in facing these challenges like welcoming our guests.We can't depend on old ways.For example,new kinds of services might replace old ones.Even simple things like a refrigerator might change.
Think about a concert. You don't need a paper ticket to pass the door;everything is digital( 数 字 式的),and you can use digital cash from your digital wallet. The future shall be full of both exciting changes and challenging tasks, but if we accept and develop new ideas,we can create a better world.
