Sample answer：

　　The person that really influenced me most was Ms. Xing---my college teacher who taught us English literature.

　　Her class was quite different from the other teachers. In her class we were not expected to sit there and listen. We had to get more involved in the class activities, like discussions, comments or debates sometimes. Our creativity and imagination were developed enormously through the active participation.

　　On the other hand, she let us think more about life by sharing her experiences and more importantly, she taught me how to live on my own. So that's why I was greatly influenced. Not only did she give me knowledge, but also she gave me courage and confidence as well.
