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 dead 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
men to dig a deep hole and put the rats in it. Soon there were no more rats, and the Government did not
pay any more money.
