During my high school years, I was interested at many subjects likes biology, history, geography and English. I find math, physics and chemistry very interesting. But I could hardly remember the event in history or the facts about geography. I couldn't remembers all the English words very well, too. However, physics and chemistry were quite easy for me. After I considered my interests and skills careful, I felt that science would be best choice (选择). So I was decided to study natural science at college, but I wanted to return to school to teach after graduation.
