　　Dear Petty,

　　I hope you didn’t make any plane for this weekend. You know I am moving into the new house, and I sincerely invite you to come to my new house. I will hold a celebration party on Saturday night. The scenery here is fantastic that I am sure you will like it. On Saturday, you can walk around my house after you get here. The party will begin at 7:00. You can live in my house that night. On Sunday, we can go fishing or play table tennis. So please do some preparation for them. You can drive here and you will see a board “Kelly’s Home” near the road. It only takes you one hour to get here. I hope there will be nothing stopping you to come.

　　Yours affectionately,

　　Kelly

　　亲爱的贝蒂：

　　希望你这个周末没有什么安排!你知道我就要搬到新房了，我真诚的邀请你来我的新房。星期六晚上我会举行一个庆祝晚会。那里的景色漂亮迷人，我相信你一定会喜欢的。星期六到这里后你可以在我家到处看看。晚会将在7点开始，到时候你可以住在我家。你可以开车过来，然后你会看见路边的一块板上写着“凯丽家”。你到这里只需一个小时，我希望你不会有什么事情而不能来。
