【回答】
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?
I sincerely hope you can accept my apology and understand my situation.
Yours,
Li Hua
