I often dream of become a teacher. I dream of standing on the platform in the classroom and give lessons to lovely boy 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 teach well. What’s more, you have to be friends with your students and take good care of him. Only in this way can you be a good teacher and win respect from them. Though I am student now, I still work hard to make my dream to come true.
