For grammar, I would recommend reading news sites, such as cnn.com or bbc.com. Even people that speak English everyday do not always use proper grammar, so I would not take what people say as proper necessarily. On the other hand, it is how people talk...

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.

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
