Apart from speeches，in my point of view，we can use our eyes to express ourselves.And through one's eyes，we can read sorrow，happiness，encouragement，and many other emotions.Eyes are always the most direct organs to reveal our thoughts.

Until now I still remember an experience，which happened when I took part in a singing contest at the age of nine.It was the power of my mother's eyes that encouraged me to go for it.I had shown great interest in singing before that，but I was too shy to sing in public.So one day my mother took me to sign up for the singing contest.With my mother's company and encouragement，I was determined to meet that challenge.Standing on the stage，I suddenly found I had become the focus of all attention.I got so nervous that I couldn't even keep my eyes open.When it was my turn to be introduced to the audience and sing，I became even more nervous.I felt my legs were shaking and my memory seemed to have left me-I couldn't remember anything.Searching for help，I met my mother's eyes which were sparkling with encouragement and strong power.It seemed that they were speaking to me，"Take it easy.You can do it！I'll always be with you！"I read the message in her eyes and at that moment I got my confidence back and began to sing my song.When I came down from the stage，she came up to me，saying，"Great！I'm proud of you！" and gave me a big hug.At that moment，I saw her eyes filled with tears of joy.Sometimes，you see，just a look of encouragement from a loved one can make a shy person brave.
