求翻译：现在大学校园里，迟到，早退，旷课是常见现象。保证学生的出勤对大学教育有很大的重要性。保证学生按时上课，能有效提高学生的学习成绩。作为一个大学身我会以身作则不迟到，不早退，不旷课，上课认真学习老师讲的知识，下课认真复习。是什么意思？

Now the campus of the University, being late, leave early, absenteeism is a common phenomenon. Ensure the attendance of students on university education has great importance. Ensure that students in class on time, can effectively improve the academic achievement of students. As a University I would set an example not to be late, do not leave early, not truancy, seriously studying in class the teacher knowledge, conscientiously review class.
