阅读下面短文,并根据短文后的要求答题(请注意问题后的字数要求)。

Work is a very important part of life in the United States. When the early Protestant immigrants(新教徒移民) came to this country, they brought the idea that work was the way to God and heaven. This attitude, the Protestant Work Ethic(道德规范), still influences America today. Work is not only important for economic benefits, the salary, but also for social and psychological need, the feeling of doing something for the good of the society. Americans spend most of their lives working, being productive. For most Americans, their work defines them: they are what they do. What happens then, when a person can no longer work? Almost all Americans stop working at age sixty-five or seventy and retire. Because work is such an important part of life in this culture, retirement can be very difficult. Retirees often feel that they are useless and unproductive. Of course, _______________; but leaving one’s job, whatever it is, is a difficult change, even for those who look forward to retiring. Many retirees do not know how to use their time or they feel lost without their jobs.

Retirements can also bring financial problems. Many people rely on Social Security checks every month. During their working years, employees contribute a certain percentage of their salaries to the government. Each employer also gives a certain percentage to the government. When people retire, they receive this money as income. These checks do not provide enough money to live on, however, because prices are increasing very rapidly. Senior citizens, those over sixty-five, have to have savings in the bank or other retirement plans to make ends meet. The rate of inflation(通货膨胀) is forcing prices higher each year. Social Security checks alone cannot cover these growing expenses. The government offers some assistance, Medicare and welfare, but many senior citizens have to change their life styles after retirement. They have top spend carefully to be sure that they can afford to buy food, fuel and other necessities.

American society is only beginning to be concerned about the special physical and emotional needs of its senior citizens. The government is taking steps to ease the problem of limited income. They are building new housing, offering discounts in stores and museums and on buses, and providing other services such as free courses, food service, and help with housework.
