楼主对原文理解有误，试译如下

There may be times when a child is sick and unable to attend school. Excused absences will only be noted for: illness or health conditions (with doctor’s notes), legal appointments, family emergencies, or religious observations. The administration must approve of all absences in order for it to be excused. 孩子有生病的时候，也有无法上学的时候。合理缺席仅有如下：疾病或健康原因（需医生假条），法律事务，家庭意外，或者宗教节日。学校必须核准所有的缺席，以确定哪一个是合理的。
