学生上课睡觉保证书200字篇一

您好!

我在课堂上睡觉不仅影响老师对同学们传授知识，影响了老师的教学情绪，影响了同学们的听课效果，辜负了老师对我的期望，辜负了父母的辛勤劳动，也浪费了自己的宝贵时间。耽误了学习知识的大好年华。

父母辛辛苦苦工作把我送到学校让我学习知识，老师在课堂上一站就是45分钟给我传授知识，不仅劳累还要吃粉笔灰，这么辛苦只是为了让我能够学到知识，今后做一个对社会有用的人，可我却在课堂上睡觉，这是很严重的错误。

发生这种事主要是我在思想上没有重视课堂的神圣和严肃性，思想深处没有端正学习是为自己学的这一基本观点，没有深刻认识到老师教学的辛苦和父母的辛劳。没有为自将来考虑。

今后我会端正思想，培养兴趣，彻底改掉这种坏毛病，认真学习，努力上进，为将来成为一个有用的人加油!

希望老师和同学们原谅我，看我今后的行动，监督我，帮助我改掉毛病，和同学们一起进步!
