One possible version：
In the picture we see a group of children playing hopscotch happily while a boy is sitting in front of his computer，fully absorbed in a game．
This picture intends to show how children today and in the past spend their free time．In the old days, there was no modem equipment such as TV sets or computers，so children killed time，playing games outdoors．With the development of science and technology，children are so attracted by computer games that they become addicted and stay in front of the screen all day long．Unlike the kids playing hopscotch，a team game，the boy who tends to spend more time alone easily develops psychological problems such as a 1ack of a sense of cooperation and communication skills．
So in my opinion，modern science may not benefit people．
