America is a mobile society. Friendship between Americans can be close and real, yet disappears soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while, then no more, If the same two people meet again by chance, even years later, they pick up the friendship.

    This can be quite difficult for us Chinese to understand, because friendship between us flows more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

    Americans are ready to receive us foreigners at their homes, share their holidays and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

    Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don't show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. Americans, however, express their welcome at home. But they truly cannot manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves to be treated hospitably.

    For Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

Life in the future will be different from life today. Many changes will happen. But what will the changes be?

The population (人口) is growing fast. There will be more people in the world and most of them will live longer than people live now. 

Computers will be much smaller and more useful, and there will be at least one in every home. And computer studies will be one of the important subjects in school then. People will work fewer hours than they do now and they will have more free time for sports, watching TV and travelling. Travelling will be much cheaper and easier. 

There will be changes in our food, too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe no one will eat it every day. Instead (相反), they will eat more fruit and vegetables. Maybe people will be healthier. Work in the future will be different, too. Robots will do dangerous and hard work. Because of this, many people will not have enough (足够的) work to do. This will be a problem.
