去年，班里发生了这样一件事。一天中午，由于我的粗心 ,收齐书费上缴时，却发现少了 20元 ,等了一个下午也没见拾金不昧者出现。此事发生在三好班集体中该如何处理真让我费了心思。 　　不声张，教师偷偷垫上吧，是对犯错误学生的放纵，不妥；发动学生公开揭发，又会伤害犯错 Last year, such a thing happened in the class. At noon of the day, due to my carelessness, when I paid the book fee and paid it, I found that it was 20 yuan less, and I waited until one afternoon to see that I had no money. What happened to the Sanhao class and how to deal with it really cost me a lot of thought. Unspoken, the teacher secretly puts on it, it is wrong to indulge in the mistaken students; it is inappropriate to launch the student to openly expose it, and it will hurt to make mistakes.
