NOT A TEACHER
Well, Yosra Ashraf, you may think that your writing is acceptable, but judging from the couple of sentences that you have written and the incorrect usage of punctuation, I have to conclude that your writing isn't acceptable.
We can only help you, if you ask a more specific question. What kind of problems are you experiencing? Are you having problems with the pronunciation in general? Forming sentences? In general, I would say that speaking is a byproduct of listening. If you listen a lot to proper English, you will eventually speak proper English.
