    Hello, my dear teachers and schoolmates!
    My name is Li Hua. I am very happy to sharing my dream with you today.
    Everyone has his own dream, nor do I. To be exactly, my dream is to study biology in the famous university in China. I wish to become a scientist but research into cloning in the future. More importantly, I wish I could do anything useful to our society. In order to realize my dream, I was working hard at my lessons right now. I’m sure that my dream will be come true. I know that I can only achieve my goal by working hard and never giving up his dream.
    Thank you for listening me.
