English (American version) is my native language. I would be happy to help you practice it through conversation. I use Skype for language learning. Send me a message with your Skype name and we'll be good to go.
The best and most effective way of learning a language is nature's way. Think back to your childhood. How did you learn your native language? by LISTENING to the sounds that your parents and grandparents, your older brothers and sisters and other family members made, then by IMITATING those sounds and eventually by RECOGNIZING THE MEANING of those sounds. Only later did you learn to read and to write. That is exactly how I approach language learning and use Skype audio+video.
