全文：This year some twenty-three hundred teenagers（young people aged from 13—19）from all over the world will spend about ten months in U. S. homes. They will attend U.S. schools, meet U.S. teenagers, and form impressions of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world.
Here is a two-way student exchange in action. 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, a lively young man, knew little German when he arrived, but after two months’ study, the language began to come to him. The school was completely different from what he had expected-much harder. Students rose respectfully when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.
