【英语书信范文【】】Subject: Request for Extension of Deadline

Dear Mr. Johnson,

I hope this message finds you well. I am writing to kindly ask for a small extension on the deadline for the project report that is due next week.

As you may be aware, I have been working on several other tasks simultaneously, and I have encountered some unexpected challenges that have delayed my progress. While I am making every effort to complete the report as soon as possible, I believe that an additional five days would allow me to submit a more thorough and accurate version of the work.

I truly appreciate your understanding and support in this matter. Please let me know if there are any specific requirements or guidelines I should follow during this time. I will ensure that the final submission meets all the necessary standards.

Thank you very much for considering my request. I look forward to your reply.

Best regards,

Emily White
