This year 1 twenty-three hundred teenagers from all over the world will spend about ten months in U. S. 2 . They will attend U. S, schools, meet U. S. teenagers, and form 3 of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new 4 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. 5 , 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. School was completely different from what he had expected－much 6 . Students rose respectfully when the teacher entered the room. They took fourteen subjects 7 the six that are usual in the United States：There were almost no 8 activities.

　　Family life, too, was different. The father's word was 9 , and all activities were around the family rather than the individual. Fred found the food too simple at first. 10 , he missed having a car.

　　“Back home, you 11 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 12 boy, was also forming his idea. “I suppose I should criticize American school,” he says. “It is far too easy by our 13 . But I have to say that I like it very much. In Germany we do nothing but 14 . Here we take part in many outside activities. I think that maybe your schools are better in training for 15. There ought to be some middle ground between the two.”

This is the way things go in France．

   If you were French，your family might have come from another country．A quarter of French people have grandparents who came from other countries．

   If you were French，you should almost certainly live in a town or a city because three quarters of French people live in towns or cities．But perhaps you would enjoy living in the beautiful French villages．There are many different houses in different villages．

   If you were French, you would go food shopping in the supermarket，but also in the weekly open market in your neighborhood．There you would find anything from fresh vegetables to fruits，bread，cheese and meat．They all come straight from the farm．You would eat three meals a day：breakfast when you get up in the morning，lunch at about noon and dinner at about eight o'clock in the evening．

   If you were French，in July or August，like almost all French school children，you would go on vacation with your parents．You would likely go to the seashore．In winter，you might go skiing in the Alps or Pyrenees．You would be sure to see many foreigners on vacation：millions of tourists go to France every year．
