听力原文： Many people use the term career to mean the job, occupation, or vocation a person has. However, a career involves much more than a job, an occupation, or a vocation. A career is the pattern of work and work-related activities that develops throughout a lifetime. It includes the job or series of jobs a person has until retirement. There are as many kinds of careers as there are people. They vary greatly in the type of work involved and in the ways they influence a person's life.
Almost every adult has a career of some kind. Most people build a career to help them satisfy certain goals. Such goals might include earning a living or helping others. The best-known career pattern develops around work for pay. Most workers in such a career hold a job to support themselves and their family. However, some people build a career around activities for which they receive no money. For example, many people work to create a comfortable home life for their family. Others spend much of their time on charitable projects.
The kind of career you have can affect your life in many ways. For example, it can determine where you live and the friends you make. It can reflect how much education you have and can determine the amount of money you earn. Your career can also affect the way you feel about yourself and the way other people act toward you. By making wise decisions concerning your career, you can help yourself build the life you want.
