     Good evening, ladies and gentlemen and welcome to this of the Box Bill Tennis Club. It's good to see so

many of you here this evening. I'm sure you're all enjoyed the fine food, and that you are ready to hear our

guest speaker.

     Ladies and gentlemen, we're pleased to welcome our most famous club champion, Billy Rogers, to our

meeting.

     Billy needs no introduction because he is one of the most well-known tennis players in our country.

However, I must mention a few things about him. Billy has won the US Open three times,and Wimbledon

twice. He has won more tennis tournaments (锦标赛) than any player from this country. He has been ranked

number one in the world in both singles and doubles. He has played in the Davis Cup and the Hopman Cup

for his country. His Wimbledon victory two years ago has been called one of the bravest in the modern time.

Had he not been injured, he would undoubtedly have won a third Wimbledon Championship. Billy is regarded

by many as perhaps the finest player ever in international tennis.

     But of course Billy is much more than a tennis champion.

     He is like an ambassador for the sport and for his country. He has done great work to help children around

the world,and his generosity to children's charity funds is well known.

     And of course, Billy is the most successful graduate of our club. He won the club championships when

he was twelve-yes, at only twelve. And Billy has not forgotten where it all started. That's why he accepted

our invitation to speak to us tonight. We're proud to have played a small part in Billy's success.

     Won't you please give a big hand to our own Billy Rogers?
