[H]ow to email professor asking to pass

The Google search how to email professor asking to pass just brought someone to my post How to e-mail a professor.

So how do you e-mail a professor asking to pass? The short answer may be found on Charles Bukowski's gravestone: "DON'T TRY." You should have been talking to your professor, face to face, much earlier in the semester. It might not be too late to do so now. But no professor with a shred of integrity will respond favorably to a pleading e-mail from a student who can't be bothered to come in during office hours. So try talking to your professor. Or use PayPal.

[Yes, I like a hyphen in e-mail. Keeping it old school.]
