     Usually,when your teacher asks a question,there is only one correct answer. But there is one question

that has

millions of correct answers. That question is "What's your name?" Everyone gives a different answer, but

everyone is

correct.

     Have you ever wondered about people's names? Where do they come from? What do they mean?

     People's first names,or given names,are chosen by their parents. Sometimes the name of a grandparent or other member of the family is used. Some parents choose the name of a well-known person. A boy

could be  named George Washington Smith;a girl could be named Helen Keller Jones.

     Some people give their children names that mean good things.  Clara means "bright" ; Beatrice means

"one who

  gives happiness" ;Donald means "world ruler" ;Leonard means " as brave as a lion".

      The earliest last names,or sumames,were taken from place names.  A family with the name Brook or

Brooks probably lived near a brook (小溪) ;someone who was called Longstreet probably lived on a

long,paved road.  The Greenwood

family lived in or near a leafy forest.

      Other early sumames came from people's occupations. The most common occupational name is

Smith,which means a person who makes things with iron or other metals. In the past,smiths were very

important workers in every town andvillage.  Some other occupational names are: Carter-a person who

owned or drove a cart;Potter-a person who made

pots and pans. The ancestors of the Baker family probably baked bread for their neighbors in their native

village.  The Carpenter's great-great-great-grandfather probably built houses and furniture.

     Sometimes people were known for the color of their hair or skin,or their size,or their special abilities.  When there were two men who were named John in the same village,the John with the gray hair

probably became John Gray.  Or the John who was very tall could call himself John Tallman.  John Fish

was probably an excellent swimmer and John Light-foot was probably a fast runner or a good dancer.

     Some family names were made by adding something to the father's name. English-speaking people

added-s or -son.

     The Johnsons are descendants of John;the Roberts family's ancestor was Robert.  Irish and Scottish

people added Mac or Mc or 0.  Perhaps all of the MacDonnells and the McDonnells and the O'Donnells

are descendants of the same Donnell.
