前言

20世纪末，以计算机和通信技术为代表的信息科学和技术，对世界的经济、军事、科技、教育、文化、卫生等方面的发展产生了深刻的影响，由此而兴起的信息产业已经成为世界经济发展的支柱。进入21世纪，各国为了加快本国的信息产业，加大了资金投入和政策扶持。为了加快我国信息产业的进程，在我国《国民经济和社会发展第十个五年计划纲要》中，明确提出“以信息化带动工业化，发挥后发优势，实现社会生产力的跨越式发展。”信息产业的国际竞争将日趋激烈。在我国加入wTQ后，我国信息产业将面临国外竞争对手的严峻挑战。竞争成败最终将取决于信息科学和技术人才的多少与优劣。在20世纪末，我国信息产业虽然得到迅猛发展，但与国际先进国家相比，差距还很大。为了赶上并超过国际先进水平，我国必须加快信息技术人才的培养，特别要培养一大批具有国际竞争能力的高水平的信息技术人才，促进我国信息产业和国家信息化水平的全面提高。为此，教育部高等教育司根据教育部吕福源副部长的意见，在长期重视推动高等学校信息科学和技术的教学的基础上，将实施超前发展战略，采取一些重要举措，加快推动高等学校的信息科学和技术等相关专业的教学工作。在大力宣传、推荐我国专家编著的面向21世纪和“九五”重点的信息科学和技术课程教材的基础上，在有条件的高等学校的某些信息科学和技术课程中推动使用国外优秀教材的影印版进行英语或双语教学，以缩短我国在计算机教学上与国际先进水平的差距，同时也有助于强化我国大学生的英语水平。为了达到上述目的，在分析一些出版社已影印相关教材，一些学校已试用影印教材进行教学的基础上，教育部高等教育司组织并委托高等教育出版社开展国外优秀信息科学和技术优秀教材及其教学辅助材料的引进研究与影印出版的试点工作。为推动用影印版教材进行教学创造条件。

章节摘录

插图：Function keys: Function keys are labeledwith an F and a number, such as F1 andF2. They are used for issuing commands,not typing in characters. Desktop microcom-puters usually have 12 function keys, porta-bles often only 10.defined by the software you are using. For example, in one program, pressing F2 may print your document; in a different program, pressing F2 may save your work to disk. The documentation manual that comes with the software tells you how to use the function keys. Also, some companies make smalltemplates that fit around or above the function keys and list the commands that the function keys correspond to.Many keyboards also include built-in enhancements such as microphones,speakers, and volume control.As computers have become more widespread, so has the incidence of varioushand and wrist injuries. Accordingly, keyboard manufacturers have been giving alot of attention to ergonomics. Ergonomics is the study of the physical relation-ships between people and their work environment; that is, it is the science ofdesigning equipment for a safe and comfortable environment. Ergonomics dealswith designing efficient and safe chairs, desks, and lights. It also recommends safeviewing distances from monitors. Keyboard manufacturers, as a result ofergonomic studies, have developed ergonomically sound keyboards to help preventinjuries and for use by physically challenged individuals. （See Figure 3.3. ）
