On the first day of my senior high school, I met a nice teacher. She looked at me and said, "I am happy to have an international student in my class." I was very excited.
One day I was three minutes late for school. She told me to write my name and the word "late" on a piece of paper. In that way she could know l was late for the first time. At the beginning, I was angry. But later I understood why she did that. She was strict（严格） with every student and she did it because she wanted to teach me an important lesson: time is priceless.
I learn another important lesson during my first exam. After finishing my exam paper, I did not review the answers because it was the end of the exam time. One week later, she returned my exam paper. I found that one of my answers was wrong. A, B and C were the only choices on the paper, but I chose D instead of C. I tried to explain my mistake. "I knew C was the right answer. but I chose D." However, she told me, "I do believe you. but I am not going to forgive(原谅 ) your mistake. This will remind（提醒） you to be more careful before you hand in your papers." I knew she was right.
