someone who contributes to the society *I'm a little bit confused in verb tenses.... I think everyone contributes to the society in some way or other and i wanna talk about my mom. She was once a primary school teacher and she taught in Chinese. Everyone who met her first always think of she was a strict person because of her poker face. But after they knew her well, they changed their mind. She is really warmhearted and she takes students as her children. I still remember when i was young she almost sacrificed all of her spare time on students, not only solved problems about homework but also gave their advice about something out of classroom. Even though she spent more time on her students than me! She was such a nice teacher that many students became her friends after they graduated. Until now she still hangs out with her students who are 28 29 now and some of them are get married. I am so proud of that my mom is a great teacher. If i choose the way she walked, i will do my best to be a person like her.
