I often dream of a teacher. I dream of standing on the platform in the classroom and give lessons to lovely boys and girls. I teach them, play with them, but watch them growing up. I am always
young when I was staying with them. I know there is not easy to be a teacher. You have to learn in
order to teach. Without enough knowledges, you can never learn well. What is more, you have to
be friends with your pupils and take good care of him. Only by this way can you be a good teacher
and win respect from them. Though I am a student now, I will work as very hard to make my
dream come true.
