Dear Dr.XX,

I am a first year graduate student from the department of XX at XX University, and I am investigating XXX now. I found that your article titled XXX is closely related to my research; however, I cannot get it through the databases my university purchased. Could you send me the full text of that paper? Thanks in advance.

Good luck with you research.

I send an email to you asked for the full text of your paper titled XXX XX days ago but have not received your reply, I guess maybe you are too busy or you have not received the email.
