Yesterday and Today

Life in the twenty-first century will be different from life today. Between then and now many changes will take place, but what will the changes be?

The population is growing fast. There will be many 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 schools then.

People will work fewer hours than they do now and they will have more free time for sports, watching TV and travel. Traveling will be much cheaper and easier. And many more people will go to other countries for holidays.

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 they will eat more fruit and vegetables. Maybe people will be healthier.

Work in the future will be different, too. Dangerous and hard work will be done by robots. Because of this, many people will not have enough work to do. This will be a problem.

American cities are similar to other cities around the world: In every country, cities reflect（反映）the values of the culture. American cities are changing, just as American society is changing.
After World War Ⅱ, the population of most large American cities became smaller; however, the population shifts（转移）to and from the city reflect the changing values of American society. In the late 1940s and early 1950s, city residents（居民）became richer. They had more children so they needed more space. They moved out of their flats in the city to buy their own homes. They bought houses in the suburbs（郊区）.
Now things are changing. The children of the people who left the cities in the 1950s are now adults. Many, unlike their parents, want to live in the cities. They continue to move to Sun Belt cities and older ones of the Northeast and Midwest. Many young people are moving back into the city. They prefer the city to the suburbs because their jobs are there; or they just enjoy the excitement and what the city offers.
This population shift is bringing problems as well as some advantages. Countless poor people must leave their flats in the city because the owners want to sell the buildings or make flats for sale instead of for rent（租金）. In the 1950s, many poor people did not have enough money to move to the suburbs; now many of these same people do not have enough money to stay in the cities.
Only a few years ago, people thought that the older American cities were dying. Some city residents now see a bright, new future. Others see only problems. One thing is sure: many dying cities are alive again.
