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