     In Europe, people make friends across the borders through town twinning.  Two towns in different

countries decide to become twin towns.

    Their citizens find pen-friends in the twin town.  They exchange newspapers and stamps.  The school

discuss teaching methods with the teachers in the twin town.  Officials visit the twin town for celebrations.  Ordinary citizens travel to the twin town, too, but not very often if it is far away.

     Sometimes schools even exchange school classes for two or three weeks! For example, Cerman

middle school students study for a while at the school in Britain, staying with British families.  A few

months later,their British friends come to study in Germany.

     Some towns even arrange exchange visits for theatre groups,chorus (合唱队 ) and  orchestras (管

弦乐队) .  Others send lectures to the twin town who tell the people there all about their own town, and

show photos and slides.

    Some towns organize exhibitions to show works of art, for example paintings by artists from their own

town.

    Many British towns are so pleased with the result of the twinning that they set out to find more than one

twin town!

    Tonbridge, a medium-sized town in Kent, for example,has twin towns in Germany and in France.  

Richmond near London has links with Cermany,France and a town in former Yugoslavia.
