Practice! If you can afford it, consider an English conversation class or private Skype lessons. If you cannot afford that, then you can consider forming your own English conversation meet-up groups or a Skype language exchange with anyone who wants to learn Arabic. Do you have children, younger siblings, or young family members? I practice speaking my second language with my young children. They can't correct errors, but they can help listen to you so that you can practice language flow.
