When asked if what I want to be in the future, I often answer with pride, “I wanted to be a teacher like my father.” Though my father is in forties, he is friendly to everyone and is easy to make the friends with. He has good ways to make it easily for his students to understand his lessons. Beside, he is not only strict with his students but also very hardworking. That’s because all his students look up to him. As is generally believed that he is one of the best teacher in his school. I now study hard, and I hope my dream of be a teacher will come true one day.
