根据短文内容回答问题。

     In the United States, many have been told that anyone can become rich and successful if he works hard

  and has some good luck.

     Yes,  when one becomes rich,  he wants people to think he is.  That's what "Keeping up with the

 Joneses" is about, because "Jones" is a very important name in the United States. The expression was first

  used in 1913 by a young American named Arthur Momand.  Momand looked around him and noticed

 that many people do things to keep up with their neighbors: They try to look as rich and successful as their

  neighbors.  He saw the funny side of it and started to write a series ( 连载) of short stories.  He called it

 "Keeping up with the Jonese".  "Keeping up with the Joneses" came to mean keeping up with the people

 around you.  Momand's series appeared in different newspapers across the country for over 28 years.

     People never seem to get tired of keeping up with the Joneses.  That is one reason why they read the

 "right" books, go to the "right" universities and cat ini the "right" restaurants.

     Every city has an area where people want to live because others will think better of them if they do.  

 And there are "Joneses" in every city of the world.  But one must get tired of trying to keep up with the

 Joneses, because no matter what one does, Mr Jones always seems to be ahead.
