When James Watt built his big steam-engines for industry, he invented a feedback device, a system which now plays a vital part in automation.
Feedback【B1】that a machine can control its own【B2】. Watt's invention was the "governor",【B3】task was to keep the engine speed【B4】, detect an unnecessary or dangerous【B5】of engine power, and reduce it【B6】closing the steam valve.
No one would suggest that a machine with such a【B7】device can "think". Let's look at some modem electronic【B8】which is not as easily understandable【B9】that of Watt's "governor". The British scientist, Dr. Gray Walter, built two【B10】"tortoises" in the 50's. It was really difficult to believe that these animals were【B11】but assemblies of electronic components and batteries. They could "see" an electric light trod approach it; they could negotiate obstacles【B12】their path such as a book by going【B13】it; they were able to【B14】bumping into each other; and they ran back to their【B15】place when they felt "hungry", in other words, when their batteries were getting low.
They would even have "nervous break-down"; two lamps【B16】of one made them uncertain—which they should approach, and one could almost feel their agony of being unable to decide what to do,【B17】the little things move here and there【B18】their batteries needed recharging. The artificial tortoises or any other electronic devices have of course no brain with which to think. All they did is to【B19】the instructions we give them; this, however, they can do very well, under the【B20】of man.
【B1】
A．gives
B．means
C．allows
D．forbids

Work is a very important part of life in the United States. Americans spend most of their lives working. For most Americans, their work defines them. They are what they do. What happensd, then, when a person can no longer work？
Most Americans stop working at the age of sixty-five or seventy and retire. Because work is such an important part of life in American culture, retirement can be very difficult for Americans. Retirees often feel that they are useless and unproductive. Of course, some people are happy to retire, but leaving one's job, whatever it is, is a difficult change, even for those who look forward to retiring. Retirement can also bring financial problems. Many people depend 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. Sometimes these checks do not provide enough money to live on, because prices are prone to increasing, a process known as "inflation". Senior citizens, those over sixty-five, typically have to have savings in the bank or other retirement plans to make ends meet. In addition, many senior citizens have to change their lifestyles after retirement. They have to spend carefully to be sure that they can afford to buy food, fuel and other necessities(必需品).
Of course, many senior citizens are happy with their retirement. They have time to spend with their families or to enjoy their hobbies. Some continue to work part-time, others do volunteer work. Some, like those in the Retired Business Executives Association, even help young people to start new businesses. Many retired citizens also belong to "Golden Age" groups. These organizations plan trips and social events. There are many other opportunities for retirees.
Which of the following could be the best title of the passage？
A．Golden Age Groups
B．The American Opinion of Work
C．The Importance of Work in America
D．The Problems of Retirement in America
