How to learn English?

I'm very fond of learning languages, and I speak English (of course), a little Slovak and Spanish. But every language needs to be practiced. Reading and listening in a target language do help. So try to read books and listen to music in English as much as you can. It's the great way to learn more. Try to read a book in English every week, and use a dictionary to help you with any word you don't know. Read articles on the Internet in English about your favourute bands or film stars. Use new words soon after learning them.
