How to write a student leave note to parents?

How do parents fill in the student leave slip as follows:

Dear teacher: I am XXX's parents, and I am writing this letter to ask for leave. Because my child is in poor health recently and needs hospitalization, I need to rest for a week. I will let the children go back to the classroom as soon as possible. Thank you for your understanding.

2. Please pay close attention to the safety of children during the leave period and urge them to finish their academic tasks seriously.

3. Teacher xx: I am XX's parents. I need to take X days off, because I want to take my children on a trip. The time is from X to X. I hope the teacher can approve it.

Of course, I will try my best to cooperate with the arrangement of the school to ensure that the children will not fall behind the progress of the course during the leave period. I hope you can reply to my email as soon as possible so that I can make full preparations for my children's holiday.

Dear parents, I need to take time off for family reasons. The school has arranged a suitable replacement, and the children's study and life will not be affected. Thank you for your understanding.

6. Dear teacher: Due to some urgent matters at home, I need to take a week off for my children, from March 6th to March 7th. I will take care of things as soon as possible and let the children go back to school as soon as possible.

7. Dear XX school leader: I am the parent of XX class students in your school, and I am writing to ask for leave. Because my child needs to visit relatives in other places recently, he needs to take four days off, from XX to XX. In the meantime, I will arrange for my children to complete the corresponding homework and self-study courses to ensure that they will not have any impact on their studies. Thank you for your understanding and support. I hope my children can go back to school as soon as possible.

Dear teacher of the academic affairs office of the school: I ask for leave on behalf of my children. Because he/she has some urgent family affairs to deal with at home, he/she can't go to Chinese and physics classes tomorrow. We hope you can approve his/her leave so that he/she can finish family affairs and concentrate on the following courses.
