This year some twenty-three hundred teenagers from all over the world will spend about ten months in US homes through an exchange program. They will attend US schools ,meet US teenagers, and form impressions of the real American teenagers . American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world.

Fred, nineteen, spent last year in Germany with George's family . In turn, George's son, Mike, spent a year in Fred's home in America.

Fred, knew little German when he arrived, but after two month's study, the language began to come to him . School was completely different from what he had expected -much harder. They took fourteen subjects instead of the six that are usual in the United States.

"Back home ,you pick up some friends in a car and go out and have a good time ,In Germany ,you walk ,but you soon learn to like it."

At the same time ,in America ,Mike ,a friendly German boy ,was also forming his idea ."I suppose I should criticize American schools ,"he says ."It is far too easy by our level .But I have to say that I like it very much .In Germany we do nothing but study . Here we take part in many outside activities. I think that maybe your schools are better in training for citizens .There ought to be some middle ground between the two."
