In the end of the last term, I got a C in the English examination. When I knew the result, I wouldn't hold back my tear. My mood was terrible and I thought the world was coming to end. So after a while, I found I was wrong for I came to realize “Failure is the mother of success”. What I should do it was to find the reason that I got so bad a result. And I think this was a lesson to me and it helped me to find my shortcomings. Maybe it could help me to improving my English. So my bad mood turned into a better one.
