     The private automobile (私家车) has long played an important role in the United States. In fact, it has

become a necessary and important part of the American way of life. In 1986, sixty-nine percent of American

families owned at least one car, and thirty-eight percent had more than one. By giving workers rapid

transportation, the automobile has freed them from having to live near their place of work. This has encouraged

the growth of the cities, but it has also led to traffic problems.

     For farm families the automobile is very helpful. It has made it possible for them to travel to town very

often for business and for pleasure, and also to transport their children to distant schools.

     Family life has been affected (影响) in various ways, The car helps to keep families together when it is

used for picnics, outings, and other shared experiences. However, when teenage children have the use of the

car, their parents can't keep an eye on them. There is a great danger if the driver has been drinking alcohol or

taking drugs, or showing off by speeding or breaking down traffic laws. Mothers of victims (受害者) of such

accidents have formed an organization called MADD (Mothers Against Drunk Driving). These women want to

prevent further tragedies (悲剧). They have worked to encourage the government to limit the youngest drinking

age, Students have formed a similar organization, SADD (Students Against Drunk Driving) and are spreading

the same message among their friends.

     For many Americans the automobile is a necessity. But for some, it is also a mark of social position and for

young people, a sign of becoming an adult. Altogether, cars mean very much to Americans.
