    I often dream of being a teacher. I dream of standing in the platform in the classroom and give lessons to

lovely boys and girls. I teach them, play with them, watch them growing up. I am always young when I was

staying with them. I know there is not easy to be a teacher. Without enough knowledges, you can never teach

good. Besides, you have to make friends with your pupils and take good care of him. Though I am a student

now, but I will work very hard to make my dream comes true.
