Dear Mr Brown,                                         
    How is your stay in Beijing?                           
    I am writing to tell you a piece of excited news: I    
won the first place in Spoken English Competition of   
our city. The progress that I made it is due to your   
kind help. You spent much time helping me with my      
spoken English that I make great progress during the   
competition. I remembered your advice: "Speaking       
slowly but clearly with a smile on your face." Thank   
you very much for your time and advice.                
     I heard you and your wife would visit your school       
before long. I'm very glad and look forward to see     
you. I sent you a camera for a small gift. Please check
the mail and I hope you will like it.                  
Yours
