The Play of Power: An Introduction to American Government
James Eisenstein, Mark Kessler, Bruce A. Williams and Jacqueline Vaughn Switzer. The Play of Power: An Introduction to American Government. New York St. Martin's Press, 1996. 639 pp. Tables, appendices, glossary, references, index.
ISBN 0 - 312 - 13662 - 5
There are dozens of American Government textbooks on the market, many of them very respected and successful, some even regarded as classics in their umpteenth(无数次的) edition. Frequently there is little that distinguishes one from another, other than an idiosyncratic (特殊的) "conceptual framework," the number and kinds of graphics, boxes, and photos, or the package of ancillary(辅助的) materials available to the adopter. The Play of Power: An Introduction to American Government is typical of the standard American Government textbook on the market. It provides balanced coverage of political and constitutional history, American political institutions and processes, and political participation. This basic version does not include separate chapters on public policy, but many policy issues are addressed in the coverage of the congress, the presidency, the bureaucracy, the courts, and interest groups.
The chapters are organized in a logical sequence but they are written so that they may be used in an alternative sequence if an instructor would so desire. The writing style. is very straightforward and not unnecessarily academic and jargonistic. The tone is respectful of students and their experiences and, despite multiple authors, it remains consistent throughout the text.
There are a number of features of The Play of Power that make it attractive and that make it one of the textbooks that I have used with satisfaction for several years. As is suggested by the title, the authors describe politics as a game of power played by many players, though theirs is not an application of formal game theories to politics. Instead, they ask students to think of a number of familiar games, like basketball or Monopoly(强手棋), and the ways that the rules, strategies, and resources shape how players go about pursuing their goals and with what effect. The authors invite students, then, to look at politics as a game a "grand" game with sometimes deadly consequences that is shaped by certain rules (some found in the Constitution), that is played by many players (politicians, voters, organized interests, etc.) who bring various and unequal resources (money, status, connections, etc.) to the game, and who win various material and symbolic outcomes. The "game of politics" metaphor is sometimes difficult to sustain throughout the coverage of many topics, but it provides a useful organizational framework. It dashes some of the idealistic notions of American government and politics that students may have picked up in high school civics classes, as well as the more cynical notions that they pick up in the popular media. In the end, I think it is useful in helping students make sense of who gets what, and how, as well as who does what, and why and with what success.
Another attractive feature of The Play of Power is a serious, consistent, and ultimately successful effort to draw on students' own experience to uncover the relevance of politics and government. The authors compare and contrast political issues and dilemmas to student issues, to student relationships among themselves, with the university, with their parents, and with local government. This helps students see the rule -making and choice -making, as well as the tradeoffs(权衡) of the political process.
The authors of The Play of Power also pull off fairly effectively the challenge of describing the roles of minorities and women in American political history and contemporary politics. This has become an increasingly common undertaking for authors of American government textbooks. Some authors wea

Conventional computers function by following a chainlike sequence of detailed instructions. Although very fast, their processors can perform. only one task at a time. This approach works best in solving problems that can be broken down into simpler logical pieces. The processors in a neural-network computer, by contrast, form. a grid much like the nerve cells in the brain. Since these artificial neurons are interconnected, they can share information and perform. tasks at the same time. This two-dimensional approach works best at recognizing patterns.
Instead of programming a neural-network computer to make decisions, its maker trains it to recognize the patterns in any solution to a problem by repeatedly feeding examples to the machine. This process is like a process that prepares all possible moves in a chess game and try to find a best approach to it. If the examples are not sufficient or complete, the computer will be in for trouble, after all, it can not respond to something it can not recognize as a pattern in its memory.
Neural networks come in all shapes and size. The new networks will make things which were simply impossible completely feasible in the near future. What the users need to do is to wait and see. Developers are experimenting with new equipment and hopefully they will succeed. Until now most existed as software simulations because redesigning computer chips took a lot of time and money. By experimenting with different approaches through software rather than hardware, scientists have been able to avoid costly mistakes.
What does the word "stump" in paragraph 1, line 2, mean？
A．Catch.
B．Baffle.
C．Please.
D．Force.

Automation
The term automation was coined around 1946 by the automobile industry to describe the increased use of automatic devices and controls in mechanized production lines. Today, it is widely used in a manufacturing context but is also applied outside of manufacturing in connection with a variety of systems in which there is a significant substitution of mechanical, electrical, or computerized action for human effort and intelligence. An operation is commonly described as automated if it is Substantially more automatic than its predecessor.
In its most general usage, automation can be defined as a technology concerned with carrying out a process by means of programmed commands combined with the automatic feedback of data relating to the execution of those commands. The resulting system is capable of operating without human intervention. The development of this technology has become increasingly dependent on the use of computers and computer-related technologies. As a consequence, automated systems have become sophisticated and complex. Advanced systems of this sort now represent a level of capability and performance that surpass in many ways the abilities of humans to accomplish the same activities.
Automation technology has matured to a point where a number of other technologies have developed from it and have achieved a recognition and status of their own. Robotics is one such technology. It is a specialized branch of automation in which the automated machine possesses certain characteristics. The most typical humanlike characteristic of a modern industrial robot is its powered mechanical arm. The robot's arm can be programmed to do a sequence of motions to perform. useful tasks, such as loading and unloading parts at a production machine or making a sequence of spot-welds on the body of an automobile. The robot will repeat the motion pattern until it is reprogrammed to perform. some alternative task. As these examples of robot applications suggest, an industrial robot is typically used to replace a human worker in a factory operation.
The field of robotics has its roots in the development of automation technology. Numerical control (NC) and telecherics are two important areas of technology that constitute the foundations of robotics technology.
Over the years, the social merits of automation have been argued by labour leaders, government officials, business executives, and college professors. No doubt the biggest controversy has focused on the employment issue: What is the effect of automation on employment？ There are other important aspects of the automation issue as well, including its effect on productivity, economic competition, education, and quality of life.
The advantages commonly attributed to automation include increased production rates, more efficient use of materials, better product quality, improved safety, shorter workweeks for labour, and reduction of factory lead times.
Automated machines are usually designed to operate at higher production rates than humans are capable of achieving. This increased productivity has been one of the biggest reasons for justifying the adoption of automated systems. Notwithstanding the claims of high quality from good workmanship by humans, automated systems are generally capable of carrying out the manufacturing process with less variability that humans make, thus yielding greater control and consistency of product quality. In addition, the increased process control makes possible more efficient use of materials, resulting in less waste.
Automated manufacturing systems often, remove workers from the workplace, thus safeguarding them against hazards in the work environment. In the United States, the Occupational Safety and Health Act of 1970 (OSHA) was enacted with the objective of making work safer and protecting the physical well-being of the worker on a
