But twenty years later this same Chaplin became the greatest, best known, and best loved comedian(喜剧演员) in the world. Nearly all visitors to cinema must have seen some of Chaplin's films. People everywhere had sat and laughed at them until the tears ran down their faces. Even people who don't understand English can enjoy Chaplin's films because they are almost silent. It isn't what he says that makes people laugh. His comedy doesn't depend on words or languages. It depends on little actions which mean the same thing to people all over the world. Acting out, without words, of common human situations plays an important part in the dances and plays of many countries. It's a kind of world language.
