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 June28th2006and have dinner together. I suggest the time for dinner would be best at7:00pm. I recalled that both of you are seafood lovers, so I will prepare lobsters and fishes as the main course, I also reserved bottles of best Italian white wine for us to enjoy at that moment. Of course if you are interested to spend a walk nearby then I am glad to accompany you.
Mary my daughter is now eight years old and she have made a lot of friends of like age since we migrated to the estate here. I am sure she will want to tell a lot of her stories when she see you both. And right now she just want me to remind you that there are swimming pool and SPA facilities associated with the estate, therefore it would be good if you like, please bring along the swimming suits, it only take five minutes walk from my house to the facilities so it is very convenient.
I am sure the above invitation would have interested you, and just to make sure things will happen as expected please kindly reply to this letter and upon then I will arrange things accordingly. Look forward to see you by then. 
My best wishes to you and your family
Yours, Raymond
