请给史密斯夫妇写一封邀请他们到你家吃饭的邀请函，时间定于2005年1月15日（星期六）晚七时：告诉他们你非常希望他们光临，并请对方给你回信。
Dear Mr. and Mrs. Smith
It has been a while since we last met, and every laughing minite filled up my memory. Recently we have the renovation of the new bought house done, and therefore would like to have the honour inviting you couple to visit us on June 28t..
