Given the advantages of electronic money, you might think that we would move quickly to the cashless society in which all payments are made electronically. 1 a true cashless society is probably not around the corner. Indeed, predictions have been 2 for two decades but have not yet come to fruition. For example, Business Week predicted in 1975 that electronic means of payment would soon "revolutionize the very 3 of money itself," only to 4 itself several years later. Why has the movement to a cashless society been so 5 in coming?

Although electronic means of payment may be more efficient than a payments system based on paper, several factors work 6 the disappearance of the paper system. First, it is very 7 to set up the computer, card reader, and telecornmunications networks necessary to make electronic money the 8 form. of payment Second, paper checks have the advantage that they 9 receipts, something thai many consumers are unwilling to 10 . Third, the use of paper checks gives consumers several days of "float" - it takes several days 11 a check is cashed and funds are 12 from the issuer&39;s account, which means that the writer of the check can cam interest on the funds in the meantime. 13 electronic payments arc immediate, they eliminate the float for the consumer.

Fourth, electronic means of payment may 14 security and privacy concerns. We often hear media reports that an unauthorized hacker has been able to access a computer database and to alter information 15 there. The fact that this is not an 16 occurrence means that dishonest persons might be able to access bank accounts in electronic payments systems and 17 from someone else&39;s accounts. The 18 of this type of fraud is no easy task, and a new field of computer science is developing to 19 security issues. A further concern is that the use of e lectronic means of payment leaves an electronic 20 that contains a large amount of personal data. There are concerns that government, employers, and marketers might be able to access these data, thereby violating our privacy.

第5题

The relationship between formal education and economic growth in poor countries is widely misunderstood by economists and politicians alike. Progress in both areas is undoubtedly necessary for the social, political and intellectual development of these and all other societies; however, the conventional view that education should be one of the very highest priorities for promoting rapid economic development in poor countries is wrong. We are fortunate that it is, because building new educational systems there and putting enough people through them to improve economic performance would require two or three generations. The findings of a research institution have consistently shown that workers in all countries can be trained on the job to achieve radically higher productivity and, as a result, radically higher standards of living.

Ironically, the first evidence for this ides appeared in the United States. Not long ago, with the country entering a recession and Japan at its pre-bubble peak, the U.S. workforce was derided as poorly educated and one of the primary causes of the poor U.S. economic performance. Japan was, and remains, the global leader in automotive-assembly productivity. Yet the research revealed that the U.S. factories of Honda, Nissan, and Toyota achieved about 95 percent of the productivity of their Japanese counterparts—a result of the training that U.S. workers received on the job.

More recently, while examining housing construction, the researchers discovered that illiterate, non-English-speaking Mexican workers in Houston, Texas, consistently met best-practice labor productivity standards despite the complexity of the building industry's work.

What is the real relationship between education and economic development? We have to suspect that continuing economic growth promotes the development of education even when governments don't force it. Alter all, that's how education got started. When our ancestors were hunters and gatherers 10,000 years ago, they didn't have time to wonder much about anything besides finding food. Only when humanity began to get its food in a more productive way was there time for other things.

As education improved, humanity's productivity potential increased as well. When the competitive environment pushed our ancestors to achieve that potential, they could in turn afford more education. This increasingly high level of education is probably a necessary, but not a sufficient, condition for the complex political systems required by advanced economic performance. Thus poor countries might not be able to escape their poverty traps without political changes that may be possible only with broader formal education. A lack of formal education, however, doesn't constrain the ability of the developing world's workforce to substantially improve productivity for the foreseeable future. On the contrary, constraints on improving productivity explain why education isn't developing more quickly there than it is.

The author holds in Paragraph 1 that the importance of education in poor countries ______.

A．is subject to groundless doubts

B．has fallen victim of bias

C．is conventionally downgraded

D．has been overestimated

Hippies were members of a youth movement of the 1960's and 1970's that started in the United States and spread to Canada, Great Britain, and many other countries. The hippies rejected the customs, traditions, and life styles of society and tried to develop those of their own. Most hippies came from white middle-class families and ranged in age from 15 to 25 years old. They thought too many adults cared about making money and little else. The term hippie may come from the word hip, which means "turned-in" or aware.

Hippies wanted a world based on love of humanity and peace. Many believed that wonderful, magical changes were about to take place. They thought these changes would happen as soon as people learned to express their feelings honestly and to behave naturally at all times. Hippies strongly opposed U.S. involvement in the Vietnam War.

Many hippies lived together in small groups, working with one another and sharing possessions. Others refused to be tied down to a fixed job or home. They wandered from place to place seeking part-time work and temporary shelter. Some begged for spare change and lived in the streets or camped in parks or other public lands.

Hippies were sometimes called "flower children" because they gave people flowers to communicate gentleness and love. They let their hair grow long and walked barefoot or in sandals. Hippies attracted public attention by wearing clothing that featured unusual combinations of colors and textures. A large number of hippies used marijuana, LSD, and other drugs. Drug experiences shaped many of their symbols and ideas.

The Beatles, a popular English rock group, helped spread the hippie movement with their song. Hippie favorites included such other rock groups as the Grateful Dead and the Jefferson Airplane, singers Joan Baez and Bob Dylan, poet Allen Ginsberg, and novelist Ken Kesey. Many hippies admired Timothy Leary, a psychologist who preached salvation through the use of drugs.

In time, most hippies realized it was not easy to reform. society by "dropping'out" of it. Some joined more organized political movements to work for specific social causes. Others turned to spirituality or religion. The majority simply left the hippie stage of their lives behind while trying to hold on to at least a few of the ideals that once inspired them.

It can be inferred from the passage that hippies called themselves "hippies" because______.

A．they wanted to be different and independent

B．they wanted people to be aware of the necessity for radical changes

C．they considered traditional values worthless

D．they begged people to notice the changes around themselves

It never rains but it pours. Just as bosses and boards have finally sorted out their worst accounting and compliance troubles, and improved their feeble corporation governance, a new problem threatens to earn them—especially in American—the sort of nasty headlines that inevitably lead to heads rolling in the executive suite: data insecurity. Left, until now, to odd, low-level IT staff to put right, and seen as a concern only of data-rich industries such as banking, telecoms and air travel, information protection is now high on the boss's agenda in businesses of every variety.

Several massive leakages of customer and employee data this year—from organizations as diverse as Time Warner, the American defense contractor Science Applications International Corp and even the University of California, Berkeley—have left managers hurriedly peering into their intricate IT systems and business processes in search of potential vulnerabilities.

"Data is becoming an asset which needs to be guarded as much as ally other asset", says Haim Mendelson of Stanford University's business school. "The ability to guard customer data is the key to market value, which the board is responsible for on behalf of shareholders". Indeed, just as there is the concept of Generally Accepted Accounting Principles (GAAP), perhaps it is time for GASP. Generally Accepted Security Practices, suggested Eli Norm of New York's Columbia Business School. "Setting the proper investment level for security, redundancy, and recovery is a management issue, not a technical one". He says.

The mystery is that this should come as a surprise to any boss. Surely it should be obvious to the dimmest executive that trust, that most valuable of economic assets, is easily destroyed and hugely expensive to restore—and that few things are more likely to destroy trust than a company letting sensitive personal data get into the wrong hands.

The current state of affairs may have been encouraged—though not justified—by the lack of legal penalty (in America, but not Europe) for data leakage. Until California recently passed a law, American firms did not have to tell anyone, even the victim, when data went astray. That may change fast: lots of proposed data-security legislation is now doing the rounds in Washington, D.C. Meanwhile, the theft of information about some 40 million credit-card accounts in America, disclosed on June 17th, overshadowed a hugely important decision a day earlier by America's Federal Trade Commission (FTC) that puts corporate America on notice that regulators will act if firms fall to provide adequate data security.

The statement "It never rains but it pours" is used to introduce ______.

A．the fierce business competition

B．the feeble boss-board relations

C．the threat from news reports

D．the severity of data leakage
