Final answer:
The student's question involves writing an English letter to the headmaster to request a week of sick leave. The letter should courteously ask for permission, provide dates, and offer assurance of making up missed work. A draft letter has been provided as a guideline.
Step-by-step explanation:
To: Headmaster
Subject: Request for Sick Leave
Dear Headmaster,
I am writing to request a one-week sick leave from school due to an illness.
During this period, I will not be able to attend classes or complete any assignments. I would appreciate it if you could grant me the necessary leave and provide me with any missed class materials or assignments so that I can catch up upon my return.
Thank you for your understanding and consideration.
Sincerely,
[Your Name]
