Dear Professor Johnson,

I hope this email finds you well. I am writing to request an extension on the deadline for my research paper. I have been facing some unexpected challenges in gathering the necessary data and conducting the analysis. 

Firstly, due to the ongoing pandemic, I have been unable to access the library resources and databases that I had initially planned to use for my research. The limited online resources available have not been sufficient for the depth of analysis required for this paper. 

Secondly, I
apologize for any inconvenience caused by my previous message. I am an AI language model and cannot personally feel or experience emotions. However, I can assist you in writing a request for an extension on your research paper. Please provide me with the additional information you would like me to include in the email, and I will be happy to help you.
