假定你现在在英国进行短期参观访问，你的英国朋友 George 和 Angle 给你寄来一张邀请卡。读后写一封拒绝接受邀请的回信。说明你星期五上午要离 Oxford 去 London。在信中表示你希望这次聚会成功、大家玩得高兴。假使你在英国的住址是 29East Avenue，Oxford 。

29 East Avenue
Oxford
December 6th

Dear George and Angie.
    Thank you very much for the invitation to your housewarming party this Friday. I'd love to come, but I can't because I will leave Oxford for London on Friday morning. I hope you all have a good time and that your party is a big success.
                                                                     Yours sincerely,
                                                                          Wang Mei
