Subject:Re:15th Sales and Marketing Conference
Dear Miss Hui,
Many thanks for your email inviting me to be the keynote speaker at your conference on Friday April 30,2010.
Much to my regret, I shall not be able to honour the invitation because I will be in Seattle, USA then.
I wish you and your conference every success and I am sure that it will greatly exceed your expectations.
Sincerely,
John Yeung
親愛的許小姐:
謝謝你給我發(fā)電郵,邀請我在你們于2010年4月30日星期五召開的會議上做主題發(fā)言。
但是非常遺憾,我無法接受你的邀請,因為屆時我將正在美國的西雅圖。我祝愿你和你們的大會取得圓滿成功,而且我敢肯定大會的成果一定會令你喜出望外。
約翰·楊謹啟
