Dear Tom,Many thanks for your invitation to ask me to attend the coming English speech contest.It is such a great honor.Much to my regret,I shall not be able to honor this invitation beacause I have already sign up a exchange-student projectwhich needs a lot of time to prepare for it.I feel very apologetic to this.It is such a big pity to lose this chance to me.And I wish you a good contest.Faithfully yours
Lily
