To keep the boy happy Robert asked the boy to do some   43   .
One morning, the boy came to Robert with a beautiful map of an island. Robert   44   that the boy had drawn a large cross in the middle of   45   . “What’s that?” he asked “That’s the    46   treasure “said the boy Robert suddenly  47   something of an adventure story in the boy’s   48   While the rain was pouring, Robert sat down by the fire to write a story. He would make the   49    a twelve-year-old boy just like Lloyd.  But who would he the pirate（海盗）?
Robert had a good friend named Henley, who walked around with the   50   of a wooden leg. Robert had always wanted to   51   such a man in a story  52   Long John Silver the pirate with a wooden leg, was   53   .
So thanks to a    54   .September in Scotland a friend with a wooden leg and the imagination of a twelve-year-old boy we have one of the greatest   55   stories in the English language.
