【正确答案】
Dear Sir,
Another exam passed. I see again cheats in the examination. Even since I entered this school, I kept seeing cheats in exams. I feel sad about this. One direct result of cheats is that less and less people are willing to spend time studying and more and more of us would rather prepare different tools for cheats. Now, few of us come to attend the class, because they know they can still pass the exam just by doing some small tricks.
I suggest strengthening the supervision against cheats. In the meantime, if the punishment is severe enough, I believe there will be less and less people cheating.
