Dear Anne,
Thank you for your invitation to dinner at your home tomorrow evening. Unfortunately, it is much to my regret that I cannot join you and your family, because I will be fully occupied then for an important exam coming the day after tomorrow. I feel terribly sorry for missing the chance of such a happy get-together, and I hope that all of you enjoy a good time. Is it possible for you and me to have a private meeting afterward? If so, please don't hesitate to drop me a line about your preferable date. I do long for a pleasant chat with you.
Please allow me to say sorry again.
Regards,
Li Ming

親愛的安：
感謝你邀請我於明日晚上與你和你的家人共進午餐。可是，我非常遺憾地告訴你我無法赴約，因為我將忙於準備後天的一門重要考試。錯過了這麼一個歡樂的聚會我深感遺憾，我希望你們能度過一個愉快的時光。對了，在我考試後我們可以見一面麼?如果可以的話請隨時給我打電話，我非常期待能和你愉快地聊天。
請允許我再一次致歉。
您真誠的，
李明
