参考解析
解析：题意想要表达的意思是只限于理论方面的研究，正确答案为D。Theoretical：理论的。附（参考翻译）：计算机将会变得越来越高级而且更易于使用。识别速度的提升将使计算机的操作更加容易。虚拟现实是使用人的感觉不计算机迚行交互的一种技术，它也会使得人机界面更好。另外，各种新奇的计算模型正在不断发展，如生物计算使用人的器官、分子计算使用具有特定属性的分子、DNA计算采用遗传的基本单元来存储数据和执行操作。到目前为止，这些都还属于未来计算平台，能力非常有限，并且只限于理论方面的研究。科学家们之所以研究这些计算模型，原因在于嵌入硅片中的微型芯片的体积的局限性，以及即使是非常小的晶体管所产生的热量方面的局限性。

Most companies expect IT (Information Technology) managers to head an IT staff of computer technicians. But IT managers can also specialize in other areas. Some managers may also be responsible for keeping their company’s Internet safety. They protect both their company and their online customers from thieves.Other managers focus more on the business rather than the technical part of computing. They become project managers, helping companies reach as many online customers as possible.Some companies also look for IT managers who can act as trainers. These trainers help a company’s computer technicians keep up-to-date on computer skills.Most companies require their IT managers to have both a bachelor’s degree and some experience in the computer field. Often, companies hire IT managers out of their existing staff of computer technicians.Since IT managers are extremely important to companies’ success, it’s no surprise that they receive such high salaries – around US $56,000 a year to start with. And, in such a fast-changing field,managers’ salaries usually increase after only a couple of years.The world will be watching to see just how quickly e-commerce replaces the old ways of doing business. And as computers change the way the world does business, IT managers will be in the middle of it all. Few companies can survive without them.Besides being the leader of computer technicians, IT managers are also expected to be ________.(A) experienced product designers(B) skilled online technicians(C) doctorate holders(D) online safety specialists

问答题Passage 2 ● Read this text about information-oriented society. ● Choose the best sentence from the opposite page to fill each of the gaps. ● For each gap (9-14), mark one letter (A-H) on your Answer Sheet. ● Do not use any letter more than once. ● There is an example at the beginning (0).New Developments for an Information—Oriented Society The astounding technological progress that is being achieved recently with electronics as the center—piece is providing our society with sophisticated means for information processing and distribution. Information channeling technology is undergoing rapid progress and has, in reality, become a decisive factor determining the very future of our society and economy. Backed by civilian factors such as diversification of philosophies of value and sophistication of needs and preferences in concert with the nation’s rising living standard, Japanese society is presently undergoing changes in the extension of economic services and in the industrial structure. Meanwhile, newly coined words such as “information channeling,” ,“software-based operations” and “de-industrialization” have come into use to make these changes tangible, and what can be said commonly in connection with these words in that.(9)______ The trend toward and information-oriented society is becoming apparent even in industry, with personnel engaged in information channeling professions increasing at a fast pace recently in all sectors of industry. These trends in both society and industry have been made possible primarily through poplar acceptance of the computer, communications equipment and data processing equipment, but further reliance on sophisticated computerized systems can be seen not only in the sector of industry but also in our daily lives.(10)______ Information channeling is undergoing remarkable progress in various sectors of society—in industrial activities, public services and, more recently, in daily living. In the sector of industrial activities, automations is continuing with the aim of increasing productivity—introduction of computers for process control by the manufacturing industry, and introduction of no machine tools, industrial robots, CAD／CAM systems and, more recently, FMS by the processing and assembling industries. Meanwhile, in offices, rapid office automation is presently in progress, stimulated by the popular acceptance of computerized systems, expansion of communications networks and the remarkable technological progress achieved in related equipment such as Japanese word processors. (11)______ Information channeling is being utilized actively in the field of public services. For example, large-capacity computers were introduced from an early stage for the control of railway trains and for extending seat reservation services, and more recently diagnostic systems utilizing computers have become commonplace in medical care to cope with the steady an aging society, research is in progress to develop technologies related to medical information systems with the aim of improving efficiency in medical services. (12)______ In the sector of administration, efficiency of clerical work is being improved through the introduction of computers, and huge volumes of administrative data are more recently being stored in data base systems. In the wake of these, computers have become indispensable for advancing large-scale RD projects as in connection with space development and atomic power development, and also in the field of basic research in life sciences.(13)______ To cope with civilian needs for more convenience in home living and in order to meet the needs raised by growing diversification of lifestyles, active research is presently in progress to develop and commercialize new media incorporating sophisticated data processing functions for use in addition to existing media involving the television, radio and telephone. In concert, research is being directed at developing technologies related to automation in the home. Progress of Science and Technology Supporting Information Channeling Electronic element technology, the foundation for progress of the computer as well as communications equipment, has undergone a steady transition form the vacuum tube, followed with the transistor and IC, to the current LSl. Progress has been so dramatic in integration rotes that, today, super LSIs integrating more than l00, 00 elements on a single circuit are being developed one after another elements on a single circuit are being developed one after another. (14)______ A. The Current State of Information Channeling in Japan. B. In our society, “information” is gaining relatively greater significance compared with material resources. C. Rapid automation and efficiency improvement are also being achieved in the sector of commodity distribution through the introduction of advanced POS systems. D. Daily living is also a sector in which information channeling is taking firm root E. This progress has led to remarkable improvements in system economy and reliability, leading to the successive development of microcomputers and elements designed for the widest range of applications. F. Introduction of Information Systems in Various Sectors of Society. G. This has resulted in computers today that feature performances that were unimaginable in the early days of the computer. H. Regarding education, computerized systems including the CAI system and CMI system are presently being put to trial operation.
