I want to become a computer programmer. I am interested
in computers. It is a whole new world.
My favourite subjects in school are mathematics, history,
and, of course, computer science
My hobby is computer games and computer programming.
I have a computer at home and can spend hours working at
it. It is much easier to do things on computer
I think that the profession of programmer can give many
opportunities. Computers are the most rapidly changing sphere
of modern technology. We are living in the age of information.
And I think that the future is just filled with computers
