A new era is upon us. Call it what you will: the service economy, the information age, the knowledge society. It all translates to a fundamental change in the way we work. Already we are partly there. The percentage of people who earn their living by making things has fallen dramatically in the western world. Today the majority of jobs in America, Europe and Japan (two thirds or more in many of these countries) are in the service industry, and the number is on the rise. More women are in the work force, than ever before. There are more part-time jobs. More people are self-employed. But the breadth of the economic transformation can't be measured by numbers alone, because it also is giving rise to a radical new way of thinking about the nature of work itself. Long-held notions about jobs and careers, the skills needed to succeed, even the relation between individuals and employers —all these are being challenged.We have only to look behind us to get some sense of what may lie ahead. No one looking ahead 20 years possibly could have foreseen the ways in which a single invention, the chip, would transform our world thanks to its applications in personal computers, digital communications and factory robots. Tomorrow's achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic changes. But one thing is certain: information and knowledge will become even more vital, and the people who possess it, whether they work in manufacturing or services, will have the advantage and produce the wealth. Computer knowledge will become as basic a requirement as the ability to read and write. The ability to solve problems by applying information instead of performing routine tasks will be valued above all else. If you cast your mind ahead 10 years, information services will be predominant. It will be the way you do your job.1.A characteristic of the information age is that （ ）.2.One of the great changes brought about by the knowledge society is that （ ）.3.By referring to computer and other inventions, the author means to say that （ ）.4.The future will probably belong to those who （ ）.5.Which of the following would be the best title for the passage?
Traditionally, the study of history has had fixed boundaries and focal points ——periods, countries, dramatic events, and great leaders. It also has had clear and firm notions of scholarly procedure: how one inquires into a historical problem, how one presents and documents one's findings, what constitutes admissible and adequate proof.Anyone who has followed recent historical literature can testify to the revolution that is taking place in historical studies. The currently fashionable subjects come directly from the sociology catalog: childhood, work, leisure. The new subjects are accompanied by new methods. Where history once was primarily narrative, it is now entirely analytic. The old questions “What happened?" and "How did it happen?" have given way to the question “Why did it happen?" Prominent among the methods used to answer the question "Why" is psychoanalysis, and its use has given rise to psychohistory.Psychohistory does not merely u
