English Names

     Most English people have three names: a first name, a middle name and the family name. Their family

name comes last. For example, my full name is Jim Alan Green. Green is my family name. My parents

gave me both of my other names.

     People don't use their middle names very much. So "John Henry Brown" is usually called "John

Brown". People never use Mr. Mrs. or Miss before their first names. So you can say John Brown, or

Mr. Brown, but you should never say Mr. John. They use Mr. Mrs. or Miss with the family name but

never with the first name.

     Sometimes(有时) people ask me about my name. "When were you born? Why did your parents call

you Jim? Why did they choose that name for you?" The answer is they didn't call me Jim. They called me

James. James was the name of my grandfather. In England, people usually call me Jim for short. That's

because it is shorter and easier than James.
