Ok,if you are really wanna make your English well,you should recite more vocabularies and read more articles at first.Secondly,you need chat with native English speakers as much as possible.The last is the most important,you need practice English listening everyday.You can listen to CNN,VOA etc.You dont need to make sure every word,you just need to adapt to the speed and the pronuication.If you can stick to do these for a long time,you will make great progress.Gook luck!!!
