Hi Herna, you could start by reading a lot (the newspaper) , watching English news channels where the words spoken are very slow and easy to understand. If you don't mind stepping down to an even more basic level- try children's books I'm pretty sure your already a little better than you know ,go ahead !

Internet is a good way. You could develop your vocabulary by using a dictionary.

well herna u should read more english novels or books about any thing u imagine but the most important is that you are love that thing like sport , policy , cooking and so on . u can also listen to any song with it lyrics thats better and if u found any one can make a convesation with u in english do never miss the chance and go ahead !
