One day, we were taking an exam. The teacher excused herself for a moment. The classroom was quiet and everyone was busy with his paper. I did well and smoothly at first, but some time later, I ran into a difficult question. I used every method but couldn’t work it out. Most of my classmates had finished and handed their papers in. I got so anxious that I wanted to cheat. But suddenly there was a voice in my mind saying: "Be honest, never cheat!" At last, I didn’t open my book, and I handed it in without answering that question. Although I didn’t get a high score, I won in the moral test. To be honest is the most important.
