题型：填空题

Most Americans enjoy moving from one place to another. They are always in constant motion. For example, they often drive their cars 120 to 160 kilometres away just to have dinner with a friend or even fly to Europe just for watching a football match. In some states only one house in five has people living in it for more than five years. One may be born in one city, and go to school in another. He may finish his middle school education in two or three cities, and then attend a college far across the country. When he has entered business, he may possibly move from job to job. Moving from job to job, which is called “job-hopping”,is a very common practice in the United States.

Job-hopping does good to workers, because every chance to change a job gives them a chance to move up to a higher position and to get better pay. And job-hopping also gives employers, bosses, managers the chance to benefit from the new ideas and skills that different people bring to their factories.
