   When Mr. David retired(退休), he bought a small house in a village near the sea. He liked it and hoped to live

a quiet life in it. But to his surprise, many visitors came to see his house in summer holidays, for it was the most

interesting building in the village. From morning to night, there were visitors outside the house. They kept

looking into the rooms through the windows and many of them even went into the house. He decided to drive

the visitors away. So he put a notice on the window. The notice said, "If you want to satisfy your curiosity

(好奇心), come in and look around. Price: twenty dollars." Mr. David was sure that the visitors would stop

coming, but he was wrong. More and more visitors came and Mr. David had to spend every day showing them
