Please give me some suggestions about that how can i speak fluently like native speakers.
I have 4 pieces of advice:
1) STUDY! You need to study the basics - grammar etc to get a good basic understanding of the language.
2) LISTEN! Watch English-language TV, films and listen to the radio (preferably stations that don't have too much music). These will all help with pronunciation and rhythm.
3) READ - You will pick up a lot of good grammar, phrases etc from books and newspapers.
4) SPEAK - Find a native conversation partner, either locally or online.
