To whom it may concern,
It is my great honour to receive your invitation to be the judge but I would like to say sorry for I can not come.
As you know, there is an importantant academic conference at the same day, and I will address a speech during the meeting. Therefore, I am affraid that it might leave no time for me ta prepare and attend your English speech competion. To make up, I would like to recommend professor Li, who is also an english teacher, as the judge, if you permit, to stand for my position.
Your understanding will be greatly appreciated, and if there is any other thing i can help please do not hesitate to contact. Finally I sincerely wish your success.
Yours faithfully,
Li Ming |
