[情景]：你请几个好朋友吃饭，也想请John来，你去John家，碰巧她不在家，为此请你用英语给他写一张50字左右留言条，告诉他：
　　为何请他吃饭；
　　吃饭后还有什么活动；
　　提醒他何时到你家。

[参考范文]
Dear John,

　　I'm having Mike and Betty at my home for dinner on Saturday, October 5th. I hope that you can come. We are going to show the film "Walking in the Clouds" after dinner. I'm sure you will be very interested in it.

　　Dinner is at 6:30. We'll be looking forward to seeing you at that time.

　　Li ming
