First of all,you can improve your accent by listening to some tapes,or you can watching American or English movies.For example:<Jaws>　

<AI>,<Jurasic Park>and so on.Then you can writing new vocabulary on pieces of paper and sticking them on your bedroom wall,and next you can look at them every night before you sleep.　

　　Finally,I think you could practice your grammer focus.Write more English sentences and paragraghs.　

　　Good luck!
