Dear Mr. and Mrs. William,

     I've learned that you are interested in Beijing Opera, so I've come to give you two

ticket for tomorrow evening's Beijing Opera at Mei Lanfang Theater. But it's real a pity

that you happened to be out. So I have to leave the tickets with this note. The  opera

will be put on by some famous actors or actresses. He is well worth watching. By the

way, I've read the two books you lent me, that are very interested. This week, I am

busy review my lessons in order to pass the final exams. I'm afraid of that I can't go to

the Opera together with you.

     I  hope you will have good time.
