When you walk along a street in a big city in the United States， you may see clocks in most stores. Radio announcers give the correct time during the day. People there think that it is important to know the time. Most Americans have watches. They want to do certain things at certain times. They do not want to be late. Not all people all over the world value time. Suppose you visit a certain country in South America. You would find that people living there do not like to rush. If you had an appointment（约会）with someone， he would probably be late. He would not care for arriving on time. In some countries in South America， even the radio programs may not begin right on time， nor do the radio announcers think it important to announce the right time. Many people regard a clock as a machine. It seems to them that a person who does everything on time is controlled（控制）by a machine. They do not want a clock or any machine to have that much power over their lives.
