    There are lots of experience in our life. The most unforgettable one for me is the speech competition holding last year. I'm interested in English. When my English teacher told me that I had chosen to take part in the speech competition, I devoted me to the preparation. I was determined to win the first prize. I was such nervous when I stood on the stage that I forgot everything. Not until I caught a sight of my teacher did I calm down. Finally, I do a good job. When I heard I got the first prize, my heart was filled in joy and tears rolled down. Through this speech competition, I understand that it is confidence which makes people succeeded.
