Today, there are very many caree for people to choose. Many people choose jobs not only to earn living but also to do their dream. Personally, I would like to become a teacher. There are many reasons why I think the work off teachers both interesting and hopeful. First of all, as a teacher, I can learn more and more thing. Especially, if i teach history or English, for example, I have to read many book to make my teaching lesson more interesting. Prepareing my teaching lesson will give me a lot of pleasure. As I prepare them, I learn many things about world and its affairs, past and present. I also learn more about people around us as well as those who are thousands of mile away in different land across the oceans. Futher, I learn more and more new words and phrases which help me to express my own thoughts and feeling better. Besides, I have to practise speaking well so as for my pupils to understand my teaching lesson. By this way, I can improve my powerof expression and my pronunciation. Secondly, the work of teachers makes me sympathetic and considerate towards others. I am very helpful to my pupils who need advice and guidance, and not critical fofr those who commit offences for mistake out of ignorance or necessity. Thus, this job helps me to speak and conduct myself with confidence and dignity which earn me the respect and admiration of others. I think it is very great. To sum up, there are many interest and benefit of teacher. I trust that my passion and attempt will help me do my dream.
