    About the year 1900,a small dark-haired boy named Charlie Chaplin was often seen waiting outside the back entrances of London theatres. He looked thin and hungry. He was hoping to get work in show business. He could sing and dance,and above all,he knew how to make people laugh.But he couldn't get work

and therefore wandered about the city streets. Sometimes he was sent away to home for children who had no parents.

    But twenty years later this same Chaplin became the greatest,best known,and best loved comedian in

the world. Any regular visitors to the cinema must have seen some of Charlie Chaplin's films. People

everywhere have laughed at them until tears have run down their faces. Even people who don't understand English can enjoy Chaplin's films because they are mostly silent. It isn't what he says that makes us laugh. It depends on little actions which mean the same thing to people all over the world. Acting out,without

words, the common human play an important part in the dances and plays of many countries. It's a kind of world language.
