Decision-thinking is not unlike. It often matters not only what you think, but also what others think you think and what you think they think you think. The mental process（过程） is similar. Naturally, this card game has often been of considerable interest to people who are, by any standards, good thinkers.
　　The great mathematician John von Neumann was one of the founders of game theory. In particular, he showed that all games fall into two classes; there are what he called games of 'perfect information', games like chess where the players can't hide anything or play tricks; they don't win by chance, but by means of logic and skills. Then there are games of 'imperfect information', like poker, in which it is impossible to know in advance that one course of action is better than another.
　　One mistaken idea about business is that it can be treated as a game of perfect information. Quite the reverse, business and life itself are games which we must normally play with very imperfect information. Business decisions are often made with many unknown and unknowable factors（因素）, as best poker players. But few business people find it comfortable to admit that they are taking a chance, and many still prefer to believe that they are playing chess, not poker.

51．Which of the following can be used in place of "Quite the reverse"?
　　A．Quite right.                   B．True enough.

52．In the writer's opinion, when making business decisions one should ___________ .
　　A．put perfect information before imperfect information
　　B．accept the existence of unknown factors

Dog Translation Products Coming to U. S.

A Japanese toy maker declares that they have developed a gadget that translates dog barks into human language and plans to begin selling the gadget——under the name of Bowlingual——in U. S. pet stores and gift shops this summer.

Tokyo-based Takara Co. Ltd. says about 300, 000 of the dog translator gadgets have been sold since it was on sale in Japan late last year. It is forecasting far bigger sales once an English language translation for dogs comes to America in August. The United States is home to about 67 million dogs, more than six times the number in Japan.

"We know that the Americans love their dogs so much, so we don't think they will mind spending $ 120 on this product," the Takara marketing manager said during an interview at a recent pet products conference in Atlanta.

Regarded as one of the coolest inventions of 2002 by Time magazine, Bowlingual is made up of a 3 - inch long wireless microphone that is fastened to a dog collar and sends out sounds to a small console (控制台) that is connected to a database (数据库). The console divides each bark into six emotional types——happiness, sadness, disappointment, anger, threat and desire——and shows common phrases, such as "You're ticking me off," that fit the dog's emotional state.

Takara says it has spent millions of dollars developing the gadget in cooperation with famous sound experts and animal behaviorists.

One thing that does appear certain is that the markets for animal translation products will likely remain a dog's world since Takara has no plans to develop a similar gadget for cats. "They are too unpredictable (反复无常) , " the marketing manager said.

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 happens, 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 this culture, retirement can be very difficult. 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. 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 ban or other retirement plans to make ends meet. The rate of inflation is forcing prices higher each year. Social Security checks alone can not cover these growing expenses. The government offers some assistance, but many senior citizens have to change their life styles after retirement. They have to spend carefully to be sure that they can afford to buy food, fuel and other necessities.
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 Executive Association, even help old people to get started in 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.
68．Which of the following could be the title of the passage?
A．“Golden Age” groups       　     B．The American Opinion of Work
C．The Importance of Work in America     D．The Problems in Retirement in America
69．Which of the following is NOT true about the retirees?
A．Some retirees feel happy as they can have more time to enjoy themselves.
B．Some retirees have to be careful with their money because of the rising prices.
C．Some retirees like to work without being paid.
D．Some retirees find work in new businesses.
70．It can be inferred from the passage that _______.
A．the Americans show their value through their work
B．the American government pays little attention to the life of the retirees
C．the retirees’ former employers offer some assistance to the retirees
D．the Americans can not find much time to travel before their retirement
71．What does the paragraph following the passage most likely discuss?

B．The difficult situation the retirees have.
C．A different opinion of the physical and emotional needs of the retirees.
D．A description of other activities the retirees can have.

The appeal of advertising to buying motives can have both negative and positive effects. Consumers may be convinced to buy a product of poor quality or high price because of an advertisement. For example, some advertisers have appealed to people’s desire for better fuel economy for their cars by advertising automotive products that improve gasoline mileage. Some of the products work. Others are worthless and a waste of consumers’ money.
Sometimes advertising is intentionally misleading. A few years ago a brand of
bread was offered to dieters (节食者) with the message that there were fewer calories in every slice. It turned out that the bread was not dietetic (适合于节食的), but just regular bread. There were fewer calories because it was sliced very thin, but there were the same number of calories in every loaf.
　　On the positive side, emotional appeals may respond to a consumer’s real concerns. Consider fire insurance. Fire insurance may be sold by appealing to fear of loss. But fear of loss is the real reason for fire insurance. The security of knowing that property is protected by insurance makes the purchase of fire insurance a worthwhile investment for most people. If consumers consider the quality of the insurance plans as well as the message in the ads, they will benefit from the advertising.
　　Each consumer must evaluate her or his own situation. Are the benefits of the product important enough to justify buying it? Advertising is intended to appeal to consumers, but it does not force them to buy the product. Consumers still control the final buying decision.

　 A. stressing their high quality

　 B. the loaf was cut into regular slices
　 C. the bread was not genuine bread

58. The passage tells us that _______.
　 A. sometimes advertisements really sell what the consumer needs
　 B. advertisements occasionally force consumers into buying things they don’t need
　 C. the buying motives of consumers are controlled by advertisements
　 D. fire insurance is seldom a worthwhile investment
59. It can be inferred from the passage that a smart consumer should ________.
　 A. think carefully about the benefits described in the advertisements
　 B. guard against the deceiving nature of advertisements
