One day I had happened to find a chatting room in my QQ, there people were chatting in
English . I tried to chat with any of them . To my surprise , I found the oral English of some
junior students were better than me. I asked them for advice but they told me practise
more on QQ. So every day after that I would spend one hour practise my oral English on QQ.
Day by day I learned many useful words and expressions. With time went by, I found that I
could even communicate with some college students free.
