给Nancy的一封信

Dear Nancy,

Im so glad to receive your invitation.But Im so sorry for you,Im afraid that I cant go to there,because I have something important at Satarday.

Thank you invite me,but I have to go to the art class and dance class,both them make me so busy on Satarday.And at night,I must go to my teachers home to do my homeworke.So its so pity that I cant attend this actiity.Tank you again for your invition,I hope you can tell me something about this activity by letters.

Yours,
