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.”

Some people have very good memories and can easily learn quite long poem（诗歌）by heart. Some people have  51  memories and can only  52  things that they have said again and again.

The  53  English writer Charles Dickens said that he could walk down  54   street in London and then tell you the name of every shop on  55  sides of the street. Great men in the world have wonderful memories.

A good memory is a great help in learning a language. Everybody learns  56 language by remembering what he hears  57  he is a small child. Some children live with their parents in foreign countries and they seem  58  two languages as  59  as one. In school it is not so easy to learn foreign languages  60  students have little time  61   it and they are busy with other subjects as well.

A man's mind is quite like a camera but it  62  photos of what we see and it can also take photos of what we feel, hear, smell and taste. When we take a real photo  63  a camera there is much work  64  before the photo is finished and ready to show to our friends.  65  the same way there is much work to do before we can keep a picture forever in our mind.

It's March, 2050.

  Frank and Mary Smith wake up in their comfortable house in the morning and switch on the bedroom computer to get the latest news. They used to read the Times, but changed to electronic newspapers many years ago.                                                

  There is the usual news about space: another space flight has returned from Mars and scientists have discovered a new planet. Then they turn to business news: the US dollar has risen greatly in Shanghai, one of the world's leading business centers. Mary tells the computer to buy 5,000 dollars, and there is a quick response that it has been done.

  As they watch the screen, Mary orders one of the household robots to make coffee for them. Frank disappears into the study to join a video conference with his partners around the world. He is a computer engineer, working for several companies. This is his third job: he used to be in marketing and then television.

  Mary has a quick look at the shopping channels - the usual selection of electric cars, household robots and cheap travel offers - before picking up the video phone to talk to her assistant. She also has a job and she is doing medical research. Both she and Frank used to have an office desk in London, but in 2014 they decided to move to the seaside and work from home.

  Frank and Mary have one daughter, Louise, who also has her own workstation at home. She goes to school only one day a week, mainly to play with other students. Classrooms disappeared in 2030 because there was no longer any need for them: communications systems have made it much easier to learn at home.

  Louise, now thirteen, is studying Chinese at present, which has become a world language as

important as English. Louise has many Chinese friends. They communicate by computer.

  According to the family doctor, Louise will live to at least 130. Her wish is to work for a

 few decades (十年) and then spend her time on music and painting.

64. Do Frank and Mary get the latest news on the computer in the morning?

65. Who makes coffee for Mary and Frank?

66. What does Frank do?

67. What are the two world languages in 2050?

68. What do you think of Louise's life in 2050? Why?
