M'y english is very bad but i need practice
Park pen, I'd like to correct your mistakes you have made.

My English is very bad, so I need practice.

In the subject box , you've written "English conversation". I guess you mean "I can't speak English well.". Don't worry because every non-native speaker has the same problem. I advise you to broaden your vocabulary by reading storys, newspapers, listening to English conversations, and watching movies. Then, try to use the words you'll learn, in sentences, or when you speak. If you want to improve your fluency, try to talk to yourself in English if there's no one to speak with. When you speak in English in front of native or non-native speakers, don't be shy, and don't be afraid of making mistakes because everyone makes mistakes, and try to be confident. My last advice is: This site is so useful. If you have any questions in mind, please post them in the right forums, and you'll get the answers to them.

PS. I'm a non-native speaker, too.

Best wishes,
