Input:  Person1:     who is your favorite NBA star ?  
 Person2:  Kobe Bryant , of course .  
 Person1:      Kobe ? I know him , the key guy of the Lakers , a heck of a NBA player . He is on fire when he breaks through enemy defense .  
 Person2:  He is competent both in driving the lane and shooting jumpers , but what really makes him formidable is his ability to switch up and dribble with his left hand .  
 Person1:      Maybe he is not good ay rebounding ?  
 Person2:  indeed , no man can be perfect . He is just so-so in crashing the boards . Usually he plays shooting guard . Rebounding might not be his strong suit .  
 Person1:      Kobe came to Beijing during this summer's Olympics . Did you go to the match between China and USA ?  
 Person2:  who wouldn't ! My friend Lee went so far as to get an autograph from him .  
 Person1:      well then , what are your spoils ?  
 Person2:  well , nothing more than a jumble of photographs .
