【答案】Dear Mr.Jackson，
I'm really sorry about my using the mobile phone in your lecture last week.Please accept my heart-felt apology for being so rude a student.
I know any word might sound a made-up excuse.But I didn't use the mobile phone for no reason.I was trying to apply to some American universities last week and that day.I got an offer and they needed my further information immediately.Therefore，I had no other choice but to try sending them a text message in class and that was exactly what I was doing when you discovered.I promise it will never happen again.But I do need my phone back to get in touch with others.Will you be kind enough to give it back to me？
Hope you can accept my apologies and understand my situation.
Yours sincerely，
