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.
