start by doin sumthing simple and sumthing dat u like
4 exmple listen 2 english songs, get the lyrics and understand d whole story by refering at ur dictionary....this way, not only u can improve ur language, but it can widen ur vocab also....=)
but the caution is, careful in choosing d songs... try 2 look for evergreen song...their english is better if u compared 2 d "hiphop" songs nowadays......
gud luck!!
