Dear Mr.Smith,

I am writing to tell yoan important change about my summer vocation schedule which I have been longing for for a long time.I am really so sorry but I have to abandon this opportunity due to some unexpected arrangement from my college.

The reason why I have to change my summer schedule is that my college has arranged for a group of students to help some poor students in a remote village.Unfortunately,I am one of them.I hope my summer schedule change won't bring yomuch disturbance.Will this winter vocation be appropriate for me to carry on my American culture tour?So excited I am when I imagine that I can experience a different Spring Festival from my home town!

Again,sorry for the schedule change and inconvenience.I am looking forward to your reply soon.

Your sincerely,
