     Today Newtown is a very clean place. Many years ago, however, there were millions of rats (老鼠) in

 Newtown. They attacked the cats and dogs.

     Sometimes a great number of them knocked down a man or woman walking home at night. The rats

 were very large and they harmed many people.

     The Government ( 政府) ordered everybody to kill rats. Most people were very lazy, so they did not

 kill them. Then the Government promised to pay some money for each clead rat. That made people very

 happy. A Government officer put all the dead rats in a big pile. Sometimes a man brought hundreds in a

 day.

     After two weeks there were not many rats in the city, but people still brought rats to the Government

 officer.  The Government officer thought that people were stealing dead rats from the pile. He ordered his

 pay any more money.
