Do you have any person in the same camp with you who also want to improve english and oral english, a few days ago, i found some website which is an organization to teach you learning english, which including testing english level for you,,,i requested the test, after that, i know my some shortage of english, they pointed out my some fault and give me some advice for how to improve my english aiming at the shortage, so i advise you can also go to do a test for yourself.

       however, in my opinion, i think the main is to learn new words by your heart and speak it out everyday, and do some speaking with others to practice your oral english, then, you will have some progress,,,do you think?
