【正确答案】 Dear Jerry,
I am very delighted to receive your invitation to attend a speech, but I must express my sincere apology to you since I am not able to accept the invitation.
Yesterday, I fell and got a nasty bang on the knee that I could not move any more, let alone take part in the speech. To make up for the problem, I would like to recommend Jimmy, who is also proficient in speech. If necessary, I shall offer some relevant advice on your activity.
Once again, I feel so sorry for any inconvenience caused. Please accept my sincere apologies.
Sincerely yours,
Li Ming
