To improve your vocabulary, I suggest you to watch more English speaking TV channels like CNN (news readers speaks much more absolved then characters in regular English shows) and read more magazines, news papers, novels etc and whenever you come across with new words, never forget to look up into the dictionary for the definition and its beneficial to note the words in to your notepad and use these words as much as you can by making sentences for yourself or while speaking with others. Well, this is how I try to improve my lexicon fertility. ( never forget to use your dictionary!!)
