【答案】Dear Mr.Jenkins，
    I would like to express my apology for not being able to teach you to make Chinese knots this Saturday.
    The reason is that I have got a cold，and the doctor suggests that I should lie in bed for one week or so.But don't worry.I've asked a friend of mine，Han Meimei，to go there instead.She is good at making Chinese knots.She will go to your apartment at 9：00 this Saturday morning.
    Please allow me to say sorry again.I have the confidence that you can learn how to make Chinese knots.
 Yours，
 Li Hua
