You need to speak english orally as much as you can through Skype or MSN Messenger, with your italki friends.

I would go to the top of the page and click on "Find a Language Partner" or click on "Groups" and join one of the many language groups we have. Good luck and hope this helps you.

Watch a lot of English movies.Watch every English movie two times. First with the subtitles , and second without subtitles.Try to repeat dialogs.There are lots of english audio books on the internet.Buy a simple mp3 player if you don't have , download them and listen wherever you go.Try to learn vocabulary in sentences, do not memorize the word itself.

Hi
For improving your knowledge in English try:
1. Listen more &more to English even in your sleeping (it helps you to make a familiar atmosphere with it).
2. Write many sentences in it from short to long ones (for improving your grammar & helping to thinking in English not in your language)
3. Repeat the sentences after hearing them carefully (as same as speaker).
4. Speak more &more even you have some mistakes on it (you can correct them one by one)
5. Get a partner to conversation or chatting.
6.practice ,practice &practice (it’s the GOLD KEY for learning every thing).

Try it
Don’t worry you can resolve your problems on it

GOOD LUCK
