There is a story which tells us about a good shop.A medical (医学的) student bought a very useful
book in the shop,but it was too expensive for him to buy.He couldn't get it from the library,
either.So every afternoon,he went there to read a few at a time.One day,however,he couldn't find
the book from its usual place and was leaving when he saw an assistant signing (示意) to him.To his
surprise,the assistant pointed to the book in a corner,"I put it there so as not to be sold out," said the
assistant.Then he left the student to go on his reading.
