Don’t Lose Your Courage
Never shall I forget the first English lesson given by Miss Liu. On that day， when she entered the classroom， we found that she was a young and beautiful lady with a big smile on her face. Then she introduced herself saying that we should call her Miss Liu instead of Teacher Liu， a moment later， she let all of us go to the blackboard and say something about ourselves in English in turn. When it was my turn， I felt so shy and fearful that I didn’t dare to say a word before the class. She came up to me and said kindly， “Don’t be afraid. I believe you can do it. Come and have a try.” My face turned red when I heard that. At last， I went to the blackboard and was able to do it quite well. She praised for what I had done. Up to now， I can still remember her words in the first English lesson： “Practice makes perfect. Don’t lose your courage when you meet with difficulties. Try on and on until you succeed.”
