Dear ,
I am deeply sorry to inform you that I did not manage to complete the task you designated last week, due to a sudden illness falling upon me these days. For the last week, I have been in a hospital with a continuous fever, which has prevented me from any activity.
To make up my fault, could you please extend my deadline to next Friday? If so, I promise I will finish the task and send my report to you via email.
I do apologize again for any inconvenience it might bring to you, and hope you could accept my apology.
Sincerely yours,
LiMing

道歉信书英文篇三：Dear David,
I am truly sorry that I cannot attend the project meeting to be held on next Tuesday afternoon.
The reason is that I am going to take a business to Shanghai by plane that day, so I will be unavailable for the meeting. However, considering the importance of the meeting, I will be grateful if you could send me a brief record of the project progress by E-mail. I will check the record and send my feedback to you.
Once again, I am sorry for any inconvenience caused. Hope you can accept my apologies and understand my situation.
Yours sincerely,
Li Ming
