Jim Allan Green

  Most(大多数)English people have three names:a first name,a middle name

and the family name. Their family name comes last. For example(例如), my full

name(全名)is Jim Allan Green. Green is my family name. My parents gave(给)

me both(两者都)of my other names.

John Henry Brown

  People don't use(用)their middle names very much. So John Henry Brown

is usually(通常)called(叫做)John Brown. People never(从不)use Mr, Mrs or

Miss before(在……以前)their first names. So you can say John Brown, or Mr

Brown, but you should(应该)never say Mr John. They use Mr, Mrs or Miss with

the family name but never with their first name or middle name.

( )1. Jim Allan Green is Jim's full name.

(     )2. Most English people have two names.

(     )3. Allan is Jim Allan Green's family name.
