My best friend

My best friend is Xiao Gang. He is medium height. He is imaginative. He is kind and friendly. He is helpful and often helps the people in trouble. Once he put up a good fight with the robber and provides the police with the useful clues. Two years ago he made a robot. It looks like a real person. It can make the bed and air the rooms.

But he has some shortcomings. He often stays up late and is late for class. He can’t hand in his homework on time. He likes watching horror films.

His dream is that the earth will become a big garden in 50 years with fresh air. There’s no pollution. The public transport system is specially designed in order to be comfortable. People ride special bikes instead of cars. There is no school on the earth. Every student has a computer connected to the interplanetary network. They can study, do their homework and take exams. We can have more spare time for our hobbies.
