Now，it seems that artificial intelligence（人工智能） is becoming more and more popular in life， and it has greatly influenced the ways we live， work and play． Can you imagine that you can play table tennis with a robot one day？

Recently，a scientist has invented a special robot that can be a table tennis coach． That means people can practice table tennis not only with humans but also with a robot．

Named Forpheus，the smart table tennis robot is quite special． It can study the movements of human players and the speeds of the ball． In this way， it can exactly judge（判断）the players skill levels（KF）． Then it uses the information to change the ways to play． If the players are just beginners， Forpheus will play in a slow and easy way， but if the players are better ones， the robot will play in a faster and more difficult way． What's more， while playing， it encourages players to try their best with words like "Good job!"， "Come on!" and so on． At the same time， it gives some good chance

improve their skills． So it is both a good partner and a clever coach．

Science and technology is developing quickly these days and it's hard to imagine what will happen in the future． " In the next 20years， it will be possible that one robot teaches another to play table tennis or even Invents another one!" Takuoya， the inventor of the robot， said．
