I learn English because I think it is interesting and useful. I can read books in original. I can watch films in original. I can listen to English songs and undestand them. I can communicate with people from other countries. I can read English articles on the Internet in English. It is also useful when you go to another country and you need to ask the way. It is useful for me because I am interested in computers and almost all computer programmes and games are in English. It will be useful for me in future. Now if you want to have a good and a well-paid job you need to know English.
