What will life be in 2050? Mr. Black is one of (great) scientists in Green City. He says everything will be free in 2050. And there lots of robots in our life. They will work in (factory). People will only do simple jobs. They will help people do some housework. And people will have longer (vacation). People will have more time to take their pets like snakes or dogs a walk. And some of them will go to moon for vacation. Mr. Black says it will take us only a day (fly) there by rocket. I think Mr. Black's (predict) are great. I hope they can come .
