    3．This year some twenty-three hundred teenagers （young people aged from 13to 19）from all over the world will spend about ten months in US homes．They will attend US schools，meet US 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．Schools were 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．
    Family life，too，was different．The father's word was law，and all activities were around the family rather than the individual（个人）．Fred found the food too simple at first．Also，he missed having a car．
    "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（批评） 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（公民）．There ought to be some middle ground between the two．

    62．The world exchange programme is mainly toD．
    A．help teenagers in other countries know the real America
    B．send students in America to travel in Germany
    C．have teenagers learn new languages
    D．let students learn something about other countries
    63．Fred and Mike agreed thatC．
    A．American food tastes better than German food
    B．Americans and Germans were both frendly
    C．German schools were harder than American schools．
    D．There were more cars on the streets in America．
    64．What is special in American schools is thatD．
    A．there is some middle ground between the two teaching buildings
    B．students go outside to enjoy themselves in a car
    C．students usually take fourteen subjects in all
    D．there are a lot of after-school activities
    65．After experiencing the American school life，Mike thoughtB．
    A．German schools trained students to be better citizens
    B．A better education should include something good from both America and Germany
    C．American schools were not as good as German schools
    D．The easy life in the American schools was more helpful to students．
