I’m sorry to say that I can't go to the bookshop with you on Sunday morning as we planned last week. I am writing to apologize for breaking my promise.
Here is the reason why I can’t go to the bookstore with you. Since the final exam is just around the corner, I decide to stay at home to go over my lessons. You know, I didn’t do well in the last exam. So I want to devote all my spare time to working on my lessons in order to get good scores in the final exam.
I am wondering if we can go to the bookstore on the second Sunday in January. Sorry again for the inconvenience caused to you.

I’m terribly sorry that I’m not able to go to your birthday party this Saturday afternoon. I’m in Beijing now because my mother is seriously ill and will have an operation here. She is in bad need of my care these days, so I’m staying here to take care of her in the hospital.
I wish you a happy birthday and hope everything will go well with the party. By the way, I have sent you the latest CD of Xu Song. I hope you’ll like this birthday present.
I’m looking forward to seeing you soon.
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.
