Task 1: Talk the advantage and disadvantage of the wide use of robots. Explain your answer in details.

　　Sample

　　I think robots are important for our future for the following reasons. First, robots have been a major part of human culture for a long time already. We rely heavily on machineries. They produce cars, computers, cloths and all sort of things. Very few of what we need is made by hand nowadays. They do such a great job at these tasks, with better speed and precision than human. Second, as artificial intelligent gets better and better, they will help us to make things running more smoothly. Who knows, maybe the day machines surpass human will come sooner than we imagined.
